What Should Be Paid Attention to When Using and Installing the Frequency Converter
What Should Be Paid Attention to When Using and Installing the Frequency Converter
Now the frequency converter technology is more and more mature, and the quality of most frequency converters in the market can be recognized by customers. The scope of application is wider and wider. But as users, what should we pay attention to? Improper selection and use of frequency converter will often lead to the abnormal use of frequency converter. Even lead to equipment failure. The following points need attention;1. During model selection, it shall be noted that the voltage level is consistent with the control motor. 2. The rated current of the motor shall not exceed the rated output current of the selected frequency converter, which is generally 1.1-1.5 times the motor current. 3. Select the type of frequency converter according to the load characteristics. Generally, there are general type, fan pump type, and special type. The universal type is used for constant torque load. When the load is heavy or there is overload during operation, it is considered to enlarge one grade.The fan water pump type belongs to variable torque load, and the load is light at low speed. It is generally selected according to the requirements of actual process parameters. For example, material pumps and feed pumps in the production workshop. The special type is selected according to the load characteristics and mechanical characteristics of each automation equipment. For example, ABB frequency converter is used for the wire cutter in our factory, and Siemens S120 slope separator is used for the separator.2. Due to the high integration, compact structure and large heat dissipation of the current frequency converter. Therefore, the requirements for installation ambient temperature, humidity and dust content are high. A good operating environment must be provided. The rest is parameter setting. Due to many parameters of frequency converter, the names of various manufacturers are different. Therefore, when setting parameters, be sure to read the manual of this type of frequency converter and set it according to the manual. It cannot be set by experience.3. Operation and maintenance. During each maintenance period, the frequency converter needs to be soot blown and cleaned to keep the normal heat dissipation during the operation of the frequency converter. After each inspection and maintenance of the frequency converter, carefully check the cable plug and whether there are missing small screws and other items.

Torque Converter Replacement 1996 Plymouth Grand Caravan?
Yes it has to be put,back on,a certain way or it could mess somethings up1. what is a torque converter and what does it mean when is is out?It works as a fluid activated coupling between your engine and your transmission.The fluid being" transmission fluid".Anyway , as your engine increases rpm's from an idle ,usually around 700 rpm's , the torque converter activates. O. K. ,it looks like two round cake pans fused together.Inside it has spiraling fan blades in each half .As the fluid is churned by the engine rpms the opposing blades connected directly to the engine causes the fan blades in the half of the converter connecting to the transmission to turn , hence converting torque. What generally happens is that these blades wear down over time and/or break off.Your car may jerk at red lights or simply not move unless you really give it the gas.my advice stop driving immediately those broken blade parts will migrate through the fluid into the tranny and ruin it as well. this is the major cause of tranny failure2. How to install torque converter solenoid.?it's under the side cover, not too hard to replace.if you need to drive the car, just unplug the solenoid. trans will work ok, just wont lock up3. Integra vibrate...Torque converter?Hi That sounds like engine trouble. If it were the transmission the RPMs would be high.4. How Does a Torque Converter Work?Ever wonder what a torque converter does? The torque converter transfers power from the engine to the transmission. Without a torque converter, your automatic transmission wo not work. Cars with automatic transmissions do not have clutches, so they need a way to let the engine keep running while the wheels and gears in the transmission come to a stop. Manual transmission cars use a clutch that disconnects the engine from the transmission. Automatic transmissions use a torque converter. A torque converter is a coupling that relies on a fluid hydrodynamic to allow the engine to spin independently of the transmission. When the engine is idling, such as at a stop light, the amount of torque going through the torque converter is small, but still enough to require some pressure on the brake pedal to stop the car from creeping. When you release the brake and step on the gas, the engine speeds up and pumps more fluid into the torque converter, causing more power (torque) to be transmitted to the wheels. There are three main parts in a torque converter. The first part of the torque converter assembly is called the impeller, also known as the pump. It is filled with fluid and it spins with the engine crankshaft. The faster it spins, the more force is created as the fluid flows through it faster and harder. The impeller forces the fluid into an assembly of blades called the turbine. The turbine sits opposite the impeller and rotates as the fluid from the impeller hits its blades. As the fluid flows through the turbine, it is repeatedly transferred from the outer section to the inner section of the turbine, then returned to the impeller. This constant circulation of fluid from impeller into turbine, then back to impeller, creates a fluid "coupling." The stator reverses the fluid and sends it back to the impeller, thereby slowing the fluid. As the transmission fluid returns to the impeller to keep the cycle going is where the torque is created. At this point the fluid is flowing in a different direction than it was originally as it came out of the impeller. This is where the stator comes in. The stator is another series of fins located between the two turbines on the transmission shaft. Its blades are angled so that when the transmission fluid flows into them, it reverses direction and gets channeled back to the impeller. When the vehicle stops, the stator's one-way "clutch" causes it to stop spinning, which breaks the hydrodynamic circuit. Along with the impeller, turbine, and stator are three stages of operation. The engine provides power to the impeller, but the impeller does not rotate because the driver keeps pressure on the brake, such as when at a stop light. The vehicle does not move, but it does not stall. Acceleration occurs when the driver takes his foot off the brake and steps on the gas pedal. The impeller starts rotating faster, and there is a large difference between the impeller and turbine speed. This creates torque, and the converter produces torque multiplication, which is necessary for acceleration. As the vehicle reaches cruising speed, the turbine rotates at about the same rate as the impeller, and torque buildup stops. At this stage the torque converter is just a fluid coupling. The automatic transmission uses what is called a lockup clutch to "lock" the turbine to the impeller. This eliminates power loss and keeps the car moving smoothly. Because the impeller is mounted to the torque converter housing, and the converter is connected to the engine, the impeller gets its power from the engine. The turbine is connected to the output shaft, which sends power to the transmission. This why you might experience shaking or shuddering when something goes wrong with the torque converter. Transmission troubles could actually be the torque converter. Torque converter problems can be misinterpreted as symptoms of a failing transmission. Do not be misled into thinking you need expensive repairs, or even a full transmission replacement. An accurate Vehicle Courtesy Check by a trained, honest transmission technician will tell you what the problem is and what repairs you need. Sure, replacing the torque converter is not cheap, but it's definitely less costly than a new transmission. Diagnosing the cause of a transmission issue is not easy. AAMCO Colorado's local technicians can help. It might just be a fluid leak, or something else altogether - our transmission inspection and Vehicle Courtesy Check help us find the problems and recommend the right services. Signs of a failing torque converter are much like that of a failing transmission. Here are some things to be aware of. If your car shakes and shudders, it might mean the lockup clutch is failing or needs adjustment. You will experience the car shaking at speeds around 35-45 miles per hour. It's a problem you cannot miss. It feels like you are driving on a grated dirt road with a lot of small ridges. A worn out lockup clutch can make the transition from acceleration to cruising speed uncomfortable, to say the least - and it's a sign you need to have your transmission checked. If your car overheats regularly, it might be a sign the transmission fluid is low. Low fluid results in low pressure, which means the torque converter can not do its job. Additionally, low fluid can cause the torque converter to malfunction. If the converter is overheating, it wo not be able to transfer power from the engine to the transmission. This results in poor acceleration and excessive wear and tear on the transmission. A damaged fin in the torque converter can cause faltering in the transmission as it shifts, or the transmission to totally slip out of gear. This is due to the engine torque not being converted into the hydraulic pressure the transmission needs to shift gears. Slipping can also be caused by too little or too much fluid in the transmission. A malfunctioning or failing torque converter will cause the transmission take longer to engage with the engine. This results in high stall speeds. There is a way to test for this, but you must know your engine's and torque converter's speed specifications. It's easier to just bring your car to AAMCO and let the experts diagnose it. Strange sounds are always a sign of something troublesome... Any weird sounds such as clicking, revving, clunking, or whining indicate possible problems with the torque converter - or the transmission. Whichever the case may be, you wo not know until you pay attention to those noises, take heed, and take your car to a qualified expert transmission technician. Even a poorly built transmission will suffer from poor maintenance. Things such as wrong fluid types or incorrect amounts of fluid can cause a lot of damage to a transmission. Incorrect fluid levels usually result from a poor or nonexistent maintenance schedule, as well as ignorance of what is required to effectively maintain a car. If you do check the transmission fluid regularly, and have it changed or flushed according to the manufacturer's recommended maintenance schedule, then you should not have much to worry about. If you check the fluid yourself, be aware of not only the levels, but the colors. Here's a handy chart: Neglecting to be aware of the simple things that can help or hinder your transmission will speed its demise. Visit an AAMCO Colorado transmission repair and total car care center near you. When larger issues arise and you need transmission repair, rebuild, or replacement schedule an appointment before it's too late. If you have questions about your car's road readiness, or about car repair and maintenance topics, AAMCO Colorado can help. You can also go online and use the AAMCO Colorado Ask a Mechanic feature to submit your auto repair questions. They will be answered by a real AAMCO Colorado mechanic as soon as possible.

The output current needs to be supplied by the input power supply, in bursts. It's only the average input current that's supposed to be 1.66A, the actual current will cycle between none, and about 4A. If the input power supply has overcurrent protection, it may shut down on these peaks, messing with your converter. You need an input capacitor across the power supply, which can source these short term current peaks1.

The specs for that chipset tell us it has "Two integrated dual-link DVI display outputs", which means you can plug two monitors into it.The important thing to recognize here is that a DVI plug supports two signals--one digital, and one analog. But they (in this case) pass the same signal. A DVI-to-VGA adaptor simply ignores the digital signal, and passes the analog signal on to your monitor.If your card has three plugs, one of which is VGA, it basically just means it has a built-in DVI-to-VGA adaptor, so one of the two display outputs is connected to the VGA and (probably) the HDMI port (HDMI is basically DVI minus the analog signal optional sound info--which is irrelevant to a video card).So think of it as a video card with a DVI port, and a HDMI or VGA port.If you want three monitors, you will need another video card. Your PCI card ought to do the trick, but there can be icky driver issues to deal with. It's always easier to do that with two identical cards (as I do--I have two identical nVidia cards, each with 2 outputs, to drive my 3 monitors).You also might have better luck with another PCI card that uses different drivers

Experienced veterans know that the frequency converter not only supports the panel operation mode, but also provides an external terminal (auxiliary terminal) control mode suitable for remote and centralized control. Press in the wire of the auxiliary control terminal of the frequency converter to realize the above control circuit. Its functions are diverse and comprehensive, which is the only choice for frequency converter control today.Although the auxiliary control method of frequency converter has many advantages, the improper control circuit wiring can often affect the operation of frequency converter and sometimes cause unnecessary faults. Today, based on the work experience of some people, Xiaobian summarized the eight forbidden areas of inverter control circuit wiring. Let's have a look.1. The conductor of frequency converter control circuit shall be strictly distinguished from the main circuit cable (power line) and placed separately. This can effectively prevent the control circuit of the frequency converter from being disturbed by harmonics in the main circuit of the frequency converter.2. The wiring of the frequency converter shall be separated from the terminals or contacts of other control circuits in order to avoid high-voltage breakdown fault. Because of the fault signal of the frequency converter and the output signal of the multi-functional contact, it is very likely to drive the high-voltage AC contactor / relay.3. In order to avoid wrong operation caused by interference signal, shielded wire and twisted pair with high-quality anti-interference ability shall be selected when wiring the low-power control circuit of the frequency converter (such as the wire used by the sensor under PID control function). And it shall be wired separately from the main circuit and strong current circuit (including 200V relay program circuit).4. Take the wire length of the frequency converter control circuit 50m as the reference point (in some cases, the length is 100m, which is related to the decisive factors such as the wire section, material and signal strength). Once the wiring distance is higher than this length, the relay circuit or relay shall be used to amplify the signal.5. When crimping the control circuit wire of the frequency converter, pay attention to the polarity of the analog signal to avoid the destruction of the auxiliary control electronic circuit of the frequency converter due to the opposite polarity.6. When the frequency converter is powered on, disable the digital multimeter with buzzer function gear (the output voltage of this gear is higher than other gears) to measure the on / off of the control circuit. The reason for this is to prevent the power in the digital multimeter from being transmitted to the frequency converter control terminal through the probe, resulting in misoperation and failure!7. Because the frequency input signal of the control circuit is a small current, in order to avoid the fault caused by poor contact, two parallel nodes or twin nodes shall be used for the small signal contact.8. Cables of 0.3 0.75 square meters are generally selected for the wiring of control circuit.
Yingweiteng, Liu Jidong: Frequency Converter Technology Leads the High-end Market
Yingweiteng, Liu Jidong: Frequency Converter Technology Leads the High-end Market
In recent years, there have been changes in the field of domestic frequency converters. On the one hand, due to the expanding demand of market segments and the breaking of the monopoly ice of multinational enterprises in this field, domestic frequency converter manufacturers have sprung up in the market. On the other hand, new enterprises have various uncertainties in theory.Objectively, some domestic enterprises lack in-depth consideration of their own long-term development, resulting in uneven product quality and mixed market brands, which makes users confused. However, when the waves wash away the sand, gold always shines. Yingweiteng, the leading enterprise of domestic frequency converter, has made a strong voice of local enterprises in the industry and set an example in the industry. Previous industrial fairs have been the stage for many well-known enterprises at home and abroad to show their strengths. At this year's industrial fair, our reporter also took this exhibition platform to communicate with Mr. Liu Jidong, director and deputy general manager of yingweiteng.Technology leading force high-end marketGoodrive300 frequency converter launched by NVIDIA this year shows a series of key technologies of NVIDIA, including speed sensorless vector control technology of permanent magnet synchronous motor, static self-learning technology of permanent magnet synchronous motor, static self-learning technology of asynchronous motor, V / F low-frequency oscillation suppression technology, V / f dynamic torque promotion technology and PROFIBUS and Ethernet communication technology.In this regard, Mr. Liu Jidong's interpretation appears modest and cautious. He pointed out: "Although domestic inverter enterprises are developing at a high speed, they are still in the initial stage compared with international brands. Enterprises such as NVIDIA have to gradually come out through bit by bit accumulation. As for a series of technological breakthroughs, it is the characteristic application of NVIDIA in different industries that summarizes the technical gap between domestic inverter and foreign advanced brands, makes long-term exploration and organizes resources Finally, it broke the technological monopoly of foreign enterprises and filled the technological gap of domestic enterprises. " "At present, the products launched by NVIDIA are basically at the same level as the corresponding products of foreign well-known brands. For example, the static self-learning function of NVIDIA frequency converter is a technology that brings great convenience to customers' application in equipment commissioning. Few domestic enterprises can do it, and even the product effect of previous versions of NVIDIA is still not perfect. In this link, NVIDIA Weiteng's newly released goodrive300 product has overcome various technical difficulties and achieved breakthroughs, and these achievements are gradually accumulated, "Mr. Liu Jidong said to the point.Firm faith to build the NVIDIA modelReferring to several acquisition cases in the domestic frequency converter industry, Mr. Liu Jidong said: "It may not be good to be acquired, and it may not be bad to refuse M & A. There are obvious differences in the development path between NVIDIA and other well-known domestic frequency converter manufacturers. For example, some domestic frequency converter brands that entered this market earlier have experienced a relatively brilliant period. However, the path chosen by everyone is different. NVIDIA was officially established in 2002, and it is not too early to start At present, it has been listed in China, and the company's business is in a period of rapid development. For the key to the success of yingweiteng, I summarize it into three points: the first is the sharing mechanism, the second is to pay attention to R & D investment, and the third is the establishment of an appropriate sales model. "At the beginning of its establishment, yingweiteng was also a small-scale operation of the original ecology, but its founder's courage, respect for talents and strong desire and pursuit to attract talents have attracted countless excellent talents to join yingweiteng continuously, which is the biggest reason for yingweiteng's rapid rise. Mr. Liu Jidong said that its so-called successful enterprise mechanism is sharing and making people eager to be in the inverter industry Those who have made some achievements can join the stage of NVIDIA and realize themselves.It is this sharing culture that permeates into the enterprise construction of NVIDIA and creates the strong cohesion and creativity of NVIDIA today. Will a good company be acquired? Liu Jidong does not avoid this problem. He revealed to reporters that opportunities have indeed appeared, especially in 2006 and 2007. Moreover, some quotations were attractive enough at that time. But in the end Yingweiteng has walked out of its own way, and faith has played a role.The founders of inveterate hope to realize themselves and achieve a career. Cash out is obviously not the first choice under this concept. It is also because of this belief that inveterate has maintained independent operation and rapid development today.Unity of knowledge and practice to promote enterprise developmentMr. Liu Jidong said that inveterate is now in a stage of climbing to a higher level. While taking a long and far view and entering the high-end market, it should also pay more attention to consolidating its advantages in the middle and low-end market. Inveterate emphasizes active service, and its growing technical support service team also provides a practical basis for this concept. Emphasizing service will involve customer satisfaction The demand for manufactured products, especially in areas with high technical requirements, is often difficult or unwilling to respond by many other brands.Yingweiteng resolutely seized this opportunity. With its strong strength in technology and R & D, yingweiteng can decisively innovate in cooperation projects with Hong Kong Machinery, metallurgy and other industries, provide products that meet customers' real needs, and establish its own competitive advantage. It is this rapid response to customers' needs that provides yingweiteng with a competitive advantage in metallurgy, ports, elevators and machine tools, Energy and other fields have won many major business opportunities.Inveterate's vision is to become the world's leading and respected supplier of products and services in the fields of electrical transmission, industrial control and new energy. This vision is obviously much broader than that of frequency converters. Therefore, inveterate's layout is in full swing, and relevant new product lines or commercial mergers and acquisitions are still continuing.Liu Jidong said: "there is a saying that 'when a train gets on the track, it can run by itself'. It should be said that yingweiteng has entered a benign and basically a track of rapid development. Then, it is difficult for yingweiteng to stop if it maintains a high growth rate." However, Liu Jidong also objectively said that there must be many problems in the rapid development of enterprises, such as human resources and management system construction, which may produce many new problems. However, "under the guidance of the company's medium and long-term planning, we will practice while playing, or improve while playing." Mr. Liu Jidong told reporters optimistically.Obviously, in the field of frequency converter, inverton has always been practicing true knowledge and integrating knowledge with practice. As long as it adheres to the company's philosophy and spirit, all problems encountered will be solved.
In Order to Ensure the Safe and Stable Operation of the Frequency Converter, These Components Need t
In Order to Ensure the Safe and Stable Operation of the Frequency Converter, These Components Need t
In today's electrical control field, frequency converter is definitely the most popular star. However, as a frequency converter integrating electrical, electronic and other technologies, it is by no means a King Kong! In order to ensure the safe and stable operation of the frequency converter, its internal components need to be replaced regularly in addition to regular inspection and cleaning. Which parts need to be replaced regularly?1. Cooling fanThe power module of the frequency converter is a device with serious heating, and the heat generated by its continuous operation must be discharged in time. However, the service life of the cooling fan is limited by the bearing. After about 10000 35000 H (i.e. converted into 2 3 years according to the continuous operation of the frequency converter), the bearing, ball, motor, etc. of the fan are seriously worn, and the fan should be replaced once. It should be noted that the replacement period of the cooling fan is greatly affected by the ambient temperature. If abnormal sound and vibration are found during inspection, the cooling fan must be replaced.2. Electrolytic capacitorLarge capacity electrolytic capacitors are used in the intermediate DC circuit. Due to the influence of pulse current and other factors, their performance will deteriorate, and the degree of deterioration is greatly affected by ambient temperature and service conditions. Generally, the service life is about 5 years. The deterioration of capacitors develops rapidly after a period of time, so the longest inspection cycle is one year, and it is better to be within half a year near the end of life.3. TimerAfter using the timer for several years, the action time will change greatly, so it is best to replace it after checking the action time.4. FuseIn the DC bus circuit of large brands of frequency converters, fuses are often used to play the role of short-circuit protection. With the extension of service time, under the influence of high current impact and temperature factors, the melt material performance will deteriorate, resulting in unnecessary faults of the frequency converter. For this reason, the fuse shall be replaced every 7 years.5. Contactor / relayAfter the relay and contactor reach a certain cumulative switching times, poor contact occurs, so it needs to be checked and replaced.6. PCB circuit boardIn fact, the PCB circuit boards used inside the frequency converter, especially the switching power supply, voltage detection and other circuits, always need to bear high voltage, so the electrical insulation performance of this part of the circuit PCB board will be inversely proportional with the use time, which is very unfavorable for the use of multi-layer PCB circuit boards and some frequency converters with poor work quality. Therefore, for this part of the circuit, 7 years shall be taken as a replacement cycle.After knowing the components that may need to be replaced, we also need to pay attention to the basic requirements for replacing components:1. Determine the basic parameters and appearance of the device to be replaced. The basic parameters include external size, capacitance of capacitor, resistance value of resistor, value of GTR Darlington (current amplification factor), switching characteristics and saturation voltage of IGBT (including IPM) devices, etc. The appearance requirements include external dimensions, terminal position and installation form, and then replace the required devices according to the same requirements.2. All connectors shall be recorded or marked during disassembly to avoid dislocation during replacement or recovery.3. The contact surface between the power device and the radiator shall be evenly coated with thermal conductive silicone grease and fastened with screws.Affected by the external environment or its own structure, the frequency converter will deteriorate after being used for a period of time, which will reduce the characteristics of the equipment and even cause faults. Even if there are no obvious problems with the above six parts when they are used, it is still necessary to judge whether they can be replaced according to the service time after they are used for a long time, so as to prevent the use problems caused by the aging of their parts.The source of the article: WeChat official account: frequency converter.
