TroubleshootingMethod for adjusting the speed of asynchronous motor
How to adjust motor speed? How many methods are there to adjust motor speed? Up to now, people have researched many problems of adjusting the speed of asynchronous motors, but in general, the methods of adjusting the speed of asynchronous electric motors have their advantages and disadvantages and have not fully resolved issues such as adjustment range, energy consumption, flatness when adjusting and equipment used.
TroubleshootingSpecial conditions of 3-phase asynchronous motors
The condition of the engine working with load is the normal condition of the engine. Below we consider special cases. The condition of the engine working without load. The motor works without load (rotates but does not pull the load) or under load, the current in the motor winding is small, does not cause any harm to the motor, but is a waste of investment capital, and at the same time the power factor and output efficiency are low, causing waste of electricity. Therefore, the engine should not be operated under load or no load.
TroubleshootingHow to troubleshoot Sullair TS-32 air compressor
Currently, most air compressors use 3-phase asynchronous electric motors (large capacity air compressors) and Air compressors use 1-phase electric motors (small capacity air compressors). During the use and operation of the air compressor, there have been many incidents caused by electric motor errors such as: short circuit, electric motor fire, electric motor jam, the load current is not too high, The machine does not run at enough speed, the motor vibrates strongly and heats up quickly, Switching on the motor, the protective devices act immediately (fuse is broken, CB is activated...), The machine runs at full speed but the 3-phase current is unbalanced.... To help customers detect the phenomena early Errors, causes and remedies for motor errors in air compressors (steam machines) and 3-phase asynchronous motors as soon as possible, so that timely measures can be taken to reduce losses caused by motor errors. We would like to offer some common engine errors as follows:
TroubleshootingHow to properly move and install Compkorea air compressor
KyungWon air compressor is one of the important equipment in industries, helping to provide stable compressed air for many applications. However, during use, technical problems cannot be avoided, and one of the common problems is that the air compressor does not produce air. So what is the cause and how to fix it? Join Minh Phu to find out details in the article below.
TroubleshootingMicos 110 air compressor
Periodically checking the technical specifications for AC motors of Air Compressors (in particular) and AC Electric Motors (in general) is extremely important and necessary. It helps users minimize risks such as: short circuit, motor fire... From those checked technical parameters, users can early detect potential risks and have appropriate maintenance plans, increasing the life of the Motor and safety for the operator. In addition, after the assembly of the low-voltage 3-phase AC motor, when testing, it is also necessary to check technical parameters such as: insulation resistance, no-load and load current, working speed, etc.
Troubleshooting9 Notes when replacing electronic components for air compressor screens
During the use of the air compressor, errors occur at the control screen that are only caused by damage or burning of some electronic components. Replacing the air compressor control screen is very expensive. Therefore, replacing damaged components and reusing the screen is feasible. However, when using electronic components, you need to pay attention to the following issues
TroubleshootingNotice on Kyungwon compressor screen part 1
Due to friction and compression pressure, the compressed air temperature of a screw air compressor always remains at a temperature level of 65ºC - 90ºC. However, after a period of use, the compressed air temperature can be as high as 95ºC - 110ºC and can be even higher, leading to the machine stopping working. Operators and users should pay attention to this to take early corrective measures. The cause may be due to one or more of the following factors:

TroubleshootingSafe when working with compressed air tanks
Safe use of compressed air tanks is a very important issue. Before being put into use, compressed air tanks must be inspected and registered for use according to regulations. Equipment users must assign responsibility for managing compressed air cylinders to equipment managers in writing. Operation of cylinders is only assigned to people aged 18 years or older, in good health, who have been trained and tested to meet the requirements of professional knowledge and KTAT procedures for operating pressure equipment and must be assigned responsibility in writing by the employer.
