Common Problem

  • Q：What do you need to pay attention to when installing screw air compressor? +
    ① The air compressor should be installed in a clean, dry, well-ventilated room, without dust and harmful gases.
    ② Working environment temperature is not higher than 45℃. The relative humidity of the surrounding atmosphere should be less than 80%.
    ③ The installation ground must be solid, flat and level.
    ④ If you plan the site is an air compressor station, the appropriate compressed air handling equipment, valves and pipeline pressure vessels should be configured according to the relevant regulations.
  • Q：How to do when the air compressor can not start ? +
    There are a variety of reasons:
    ① No voltage input or abnormal voltage: Check the power supply circuit
    (2) Lack of phase (the motor emits a "buzz" sound) : check the power cord terminal and the electric controller and the wire terminal
    (3) Power phase connection error or master controller failure: replace the phase sequence and repair or replace the master
    ④ Fuse blown: confirm the check circuit is correct, replace the fuse
    ⑤ AC contactor contacts burned out or malfunction: repair or replace
    ⑥ Pressure switch (pressure sensor) failure: repair or replace
    ⑦ Motor burned out, bearing damage: repair or replacement
    ⑧ Head moving disc stuck or bearing damage caused by gridlock: repair or replacement
    ⑨ Temperature sensor action protection: find out the cause, troubleshoot
    ⑩ Current protector action protection: identify the cause, troubleshoot
