1, daily maintenance of screw air compressor
Due to the influence of ambient temperature, humidity, dust and vibration, the internal components of the inverter may be deteriorated, resulting in potential failure of the inverter or reducing the service life of the inverter. Therefore, it is necessary to carry out daily and regular maintenance and maintenance of the frequency converter.
Warning: After the power is turned off, there is still a high voltage on the filter capacitor. Therefore, the inverter cannot be maintained or maintained immediately. It must be waited until the display panel of the inverter is used to measure the bus voltage with a multimeter to not exceed 36V.
2, daily inspection items
1) Whether the sound changes abnormally during the running of the motor;
2) Whether vibration is generated during motor operation;
3) Whether the installation environment of the inverter has changed;
4) Whether the inverter cooling fan works normally;
5) Is the inverter overheated?
