Air compressor daily maintenance matters needing attention

1. Before daily or each operation of air compressor:

(1) Oil and gas barrel drainage;

(2) Check the oil level;

(3) Preparation of peripheral equipment, such as water and electricity supply, opening the compressor outlet valve, etc.

2. The air compressor runs for 500 hours:

(1) Remove and clean the air filter element, and blow it out with low pressure compressed air below 0.2MPa;

(2) The first oil filter change after the new machine is used;

(3) Replace the coolant;

(4) Clean the filter element of the air filter cup;

(5) Clean the filter element of the drain valve.

3. The air compressor runs for 1000 hours:

(1) Check the action and moving parts of the intake valve, and add grease;

(2) Clean the air filter;

(3) Inspection pipe joint fastening bolts and fastening wire terminal screws.

4, air compressor operation 2000 hours or 6 months:

(1) Check the pipelines of each part;

(2) Replace the air filter element;

(3) Replace the oil filter;

(4) Replace the filter element of the air filter cup;

5. The air compressor runs for 3000 hours or one year:

(1) Check the action of the intake valve and whether the valve plate is tightly closed;

(2) Check all solenoid valves;

(3) Check whether the protection differential pressure switches operate normally;

(4) Replace the fine oil separator;

(5) Check the pressure maintenance valve;

(6) Clean the cooler and replace the ○ ring;

7, air compressor every 20000 hours or 4 years:

(1) Replace the engine block bearings and oil seals, and adjust the clearance;

(2) measuring motor insulation, should be more than 1MΩ.
