I. Air compressor operators must be trained for safe operation in accordance with relevant national regulations and obtain a special operation qualification certificate before they can start work.

2. Check, lubricate and maintain the equipment according to the equipment operating procedures before starting up.
3. No repair work shall be carried out when the machine is running or the equipment is under pressure.
4. Air compressors are special equipment. To be carefully maintained, the compressor oil must be replaced every two months, and the compressor oil must always be kept below the oil level.
Fifth, if abnormal sounds, vibrations or other failures occur during operation, they should be stopped and repaired immediately before being allowed to use.
26. Every 16 hours of work, the drain valve under the air tank of the air compressor must be opened. After draining the waste water, close the drain valve tightly.
VII. After every 8 hours of work, the valve under the oil-water separator and the air bag valve on the dust collector must be opened. After draining the waste water, close the drain valve tightly.
8. When inspecting and repairing, care should be taken to avoid wood chips, iron chips, wiping cloth, etc. from falling into the cylinder, gas storage tank and duct.
Nine, the pressure gauge is calibrated once a year, the external inspection of the gas storage tank and the pipe joint is performed once a year, the internal inspection and the hydraulic strength test are performed once every three years, and detailed records must be made, and the working pressure and next time shall be indicated on the gas storage tank. Test date.
X. Do not adjust the relief pressure of the safety valve by yourself. Whenever pressure is released through the safety valve, you must immediately find out the cause of the excessive pressure release and deal with it in a timely manner. The filter of the air compressor must be cleaned once a month and the wearing parts must be replaced in time.
11. It is strictly forbidden to remove the safety protection device. If the safety protection device fails, it shall be shut down for maintenance immediately.
12. Keep the work place tidy, clean and meet the requirements of cleaner production.
规程 Air compressor maintenance procedures
First, when the air compressor is running, you should always pay attention to whether there is any abnormal noise. Check whether the pressure gauges and exhaust temperatures at all levels are normal.
2. There should be no air leakage, water leakage, oil leakage, etc. at all parts of the air compressor and at each connection.
3. The oil and water deposits in the intercooler and the gas storage tank should be discharged once or twice a day.
Fourth, always pay attention to whether the temperature of the lubricating oil is normal (≤70 ℃), and whether the oil level is at the prescribed height. When the amount of oil is insufficient, refuel in time.
Five more lubricating oil every two months. The new air compressor should be replaced once every 2-3 days, and repeated 2-3 times according to the degree of oil pollution.
26. For mobile air compressors, the inner cavity of the hub of the wheel and axle components is added with GB491-654 calcium-based lubricant, which is replaced once a year. The spring suspension and steering pin are filled with calcium-based lubricant No. 4. Fill in at any time according to the work situation.
7. Check the inlet and exhaust valves every 1-2 times. If there is any operation or damage to the valve discs, springs, and joint bolts, they should be replaced and eliminated in time.
8. Every half month, the filter inside the filter element relief valve should be cleaned and coated with clean lubricant.
Check the wear of connecting rod bush and connecting rod small-end bushing every three months. The gap between the connecting rod shoe and the crankshaft turning diameter is too large. When the allowable gap is exceeded, one or two thin tile mouth pads should be removed to adjust the gap properly. When the radial clearance between the small head bushing and the piston pin exceeds the allowable value, the bushing should be replaced in time.
X. Check the condition of the piston every six months, and replace the piston rings and oil scraper rings that exceed the specified values.
Eleven, check the cylinder mirror wear every six months. When there are slight scratches, you can use a semi-circular whetstone to remove it.
12. Check the crankshaft diameter and bearing every six months to make sure that there is something wrong. If there is no abnormal phenomenon, this inspection may remove the crankshaft from the crankcase.
XIII. Check and verify the pressure gauge and safety valve every six months.
14. Check and clean the intercooler every six months.
15. Check the exhaust channel, air storage tank and exhaust pipe system in the air compressor every six months, and remove the internal carbon deposits and oil pollution.
