Products to meet all the performance requirements of gas compressors, high-performance vector control technology industry-leading, can provide man-machine interface, PLC, inverter complete sets of solutions. Gas compressor main motor power is usually 55KW to 500KW, the drive optional power amplifier 1 to 2 files.
At present, there are 2 kinds of application modes of mainstream inverters in the industry:
1, Used in start-up phase, which is equivalent to soft start-up function. After start-up, it is switched to normal-frequency operation or the frequency converter is always running at 50HZ without FM. This is mainly used when compressor needs frequent start- No impact, start smooth;
2, need frequency modulation, as a result of the application of inverter, the motor is usually standard inverter motor, FM range of 30HZ to 80HZ, motor current and pressure by detecting the appropriate frequency, that is above 50HZ run to improve work efficiency and compression efficiency, It is estimated that such applications usually improve efficiency by more than 20%.
