What are the preparations before screw compressor maintenance
Good maintenance is the key to ensuring the normal operation of the unit, and it is the top priority to extend the service life of the unit. Therefore, the maintenance procedures of the screw compressor unit must be carefully implemented. Before proceeding with maintenance, at least make the following preparations:
1. Cut off the power of the host and hang a sign at the power switch;
2. Close the shut-off valve to the air supply system to prevent the compressed air from flowing back to the repaired part. Never rely on one-way valves to isolate the gas supply system;
3. Open the manual vent valve to vent the pressure in the system and keep the vent valve open;
4. For water-cooled machines, the water supply system must be turned off to release the pressure of the water pipeline;
5. Make sure the compressor unit has cooled to prevent burns and burns;
6. Wipe off the oil and water marks on the ground to prevent slipping.
caveat:
1. Don't think that the machine is shut down, it is considered that it can be repaired and maintained. The automatic control system of the machine will start the compressor at any time
2. Poor maintenance not only affects the normal operation of the unit, but also may affect the safety of the operator;
3. When the compressor is running or under pressure, do not remove the nuts, oil filler plugs and other parts;
4. Do not use probable solvents, such as gasoline or kerosene, to clean the air filter or other parts.
