How to maintain screw air compressor

The use of any machine is to the correct maintenance, in order to make the machine life long. Permanent magnet variable frequency screw air compressor is no exception, the correct maintenance of permanent magnet variable frequency screw air compressor service life and maintenance costs have a great impact, this point from the actual interests of the enterprise is very necessary.

1. Maintenance and maintenance of filter element of permanent magnet frequency conversion screw air compressor:

every 100h or the drilling rig works within a week: the primary filter screen of the air compressor oil filter and the coarse filter screen on the oil tank must be cleaned. During cleaning, the filter element must be removed and the wire brush is used to remove dirt on the screen. As the air compressor works in a dusty environment, it is very important to clean the air filter and the oil filter frequently, ignoring this point will cause a series of failures;

2. Clean the filter of permanent magnet frequency conversion screw air compressor:

every 300h: clean the air compressor filter core, blow dry after cleaning, and then soak the same oil in the oil tank. If the dust is very serious, determine the cleaning cycle according to the actual situation. When the red line of the air pollution indicator on the relief valve can be seen, it means that the air filter is seriously polluted and the air filter should be cleaned. Clean or check the relief valve, minimum pressure valve and automatic vent valve and other components. Thoroughly clean the oil filter to clean the dirt deposited on the bottom of the oil filter.

3. Maintenance and replacement of permanent magnet frequency conversion screw type air compressor oil filter paper filter element:

every 1000h: Air compressor oil filter paper filter must be replaced. Check whether the safety valve, temperature control valve, pressure regulator and pressure regulating valve work normally;

4. Check the permanent magnet frequency conversion screw air compressor oil pump to replace the sealing ring:

every 3000h: check the oil pump, check or replace the sealing ring. The emulsification degree of the base oil, the amount of impurities, and the change of viscosity should be replaced with new oil. Oil separator filter components, generally can be used for 2000~4000h. No special maintenance is performed during this time.

If the compressor oil consumption is found to be significantly increased, check or replace the core. When used in a dusty environment, the dust is easy to gather on the oil cooler, and the cooling effect deteriorates. It should be cleaned according to the specific situation. Generally, it is required to be cleaned once every 4 months to ensure the heat dissipation effect;

5. Overhaul the main machine of permanent magnet variable frequency screw air compressor:

overhaul the main engine every 10000h, and replace the radial bearing and thrust bearing if necessary.
