Maintenance of variable frequency screw air compressor

The maintenance of variable frequency screw air compressor involves many aspects. The following are some key maintenance steps and precautions:

1. Clean and replace the filter

air filter element: It is recommended to maintain the air filter element once a week to ensure its filtering effect and prevent dust and dirt from entering the air compressor.

Oil and gas separator: clean regularly to ensure effective separation of oil and gas and avoid pollution of lubricating oil.

2. Maintenance and replacement of lubricating oil

replacement cycle: The new machine should be replaced with lubricating oil after 500 hours of operation, and then every 2000 hours. When used in harsh environments, the replacement cycle should be shortened.

Oil selection: use pure special screw oil to ensure that it has good oxidation stability, fast separation, good foam cleaning effect, high viscosity and strong corrosion resistance.

Oil level inspection: check the oil level frequently, and add new oil when the oil level is too low.

3. Maintenance and cleaning of the cooler

inspection and cleaning: Check and clean the cooler regularly to ensure its heat dissipation effect and prevent the heat dissipation performance from being reduced due to dust, oil and other impurities.

4. Maintenance of other parts

oil filter: Replace it at the same time as the lubricating oil to ensure the cleanliness of the oil.

Solenoid valve: regular inspection, such as failure should be removed in time to check and replace if necessary.

Control pipeline between oil-gas separator and unloading valve: check the pipeline and connection, and repair if there is leakage.

5. Safety and Emissions

discharge of condensed water: Condensate water should be discharged frequently during the use of lubricating oil. Generally, it should be discharged once a week, and it should be discharged once 2-3 days in high temperature climate.

Safe operation: When draining oil or replacing the oil filter, open the oil drain valve slowly to avoid the pressure belt temperature lubricating oil splashing and hurting people.

By following the above maintenance steps and precautions, the normal operation of the variable frequency screw air compressor can be ensured and its service life can be extended. At the same time, regular professional maintenance and inspection are also essential to ensure the safety and efficiency of the equipment.
