First, when the air compressor can be rotated:
1. Wrong turning direction - wrong motor wiring change wiring.
2 compressor parts overheating: ① the use of high pressure - reduce the use of pressure; ② The intake pipe is too small and too long - replace the larger and shorter pipe; ③ Air filter or valve carbon blockage - remove clean; ④ The valve group is damaged or not located - sent to a special factory for repair; ⑤ Gasket leakage - replacement of new products; ⑥ Load release system damage failure - replace new products; ⑦ Piston ring or cylinder wear - sent to a special factory repair; ⑧ Speed too fast - reduce the speed; ⑨ Improper lubricating oil - refer to the instructions for proper lubrication; ⑩ The surrounding humidity is too high or poor ventilation - move to a well-ventilated place.
3. Slow return: ① voltage reduction - please check the power company; ② The wire used is too thin and too long - use thicker and shorter wires; ③ the belt is too loose - adjust the belt; ④ Motor failure - send the motor factory for repair.
4.Intense vibration: ① the exhaust pressure is too high - reduce the exhaust pressure; ② Speed is too high - reduce the speed; ③ The V-belt is not correct or the flywheel is loose - readjust; ④ Crankshaft deformation - sent to a special factory for repair.
5. The pressure can not rise or reach the specified pressure: ① the valve plate is not working properly, the valve plate is leaking - grinding or replacing the valve plate; ② Valve seat spring failure - new replacement; ③ Foreign bodies attached to the valve plate or paint - remove and clean; ④ Leakage of safety valve or automatic load release valve - disassemble, clean and repair or replace new products; ⑤ Air valve, drain valve, pipe joint and screw leakage - repair bolt or replace new; ⑥ Piston ring wear - Replace the piston ring.
6. When rotating, there is a "cough" noise: ① the valve seat is loose - lock the valve seat; ② piston impact cylinder head - thickened liner; ③ connecting rod bearing alloy wear - bearing alloy repair and replacement; ④ Pulley or key loose - bolted.
7. Pressure gauge indicator is not accurate - pressure gauge fault - Replace a new pressure gauge.
8. Belt slip: ① belt elongation is too loose - adjust the belt; ② The use pressure is too high - reduce the use pressure; ③ Old belt - Replace new belt.
9. Too much lubricating oil consumption: ① too much oil - adjust the belt; ② Piston ring wear, piston cylinder wear - new updates.
10. Motor overheating: ① pressure adjustment is too high to overload - reduce the use of pressure; ② The voltage is too low or the wire is too long - please check or replace the thicker wire with the power company; ③ Exhaust valve failure, bearing burned - new products; ④ piston burn - replace repair; ⑤ The belt is too tight and the center line is not aligned - readjust.
11. The output air volume is reduced: ① the air volume is greater than the amount of quantification - replace the air compressor with a larger force; ② The output pressure is higher than the rated pressure - reduce the use pressure; ③ The intake pipe is too small and too long - replace the larger and shorter pipe; ④ The air filter is blocked - remove and clean; ⑤ The valve group is damaged or not close - sent to a special factory for repair; ⑥ Damaged liner - new replacement; ⑦ Triangle belt loosening - readjust; ⑧ the release of load is not completely removed from the plug - adjust it; ⑨ Exhaust pipe leakage - New replacement.
12. Load release action failure: ① load release valve pressure rod head wear or other parts damage - repair; ② Load release pipeline is blocked or leaking - disassemble and clean or replace; ③ Release piston stuck dead - disassemble and repair or replace.
13. The pressure of the gas storage barrel is too high or the safety valve rings: ① the output pressure is higher than the rated pressure - lower the use pressure; ② Load release system damage, failure - repair; ③ the release pressure is set too high - reduce the set pressure; ④ Pressure gauge damaged - new; ⑤ Air leakage in the load release air pipeline - repair and replace; ⑥ The set pressure of the safety valve is too low or damaged - increase the pressure of the safety valve or replace it.
14. Valve group wear or rupture: ① Valve group dirt - remove and clean; ② High pressure - reduce the use of pressure; ③ Valve seat overheating - check whether the exhaust pipe is smooth and remove it; ④ Valve seat loose - re-lock; ⑤ Dirt, impurities into the night work seat - remove the lock; ⑥ Broken valve disc - replace.
Second, the air compressor can not be rotated:
1. No sound: ① power outage - contact the power company for maintenance; ② Wiring or fuse break - new repair; ③ Motor failure - send the motor factory to repair.
2. Motor buzzing but not starting: ① voltage reduction - power company maintenance; ② exhaust valve leakage - remove and repair the exhaust valve; ③ Wiring error - replace wiring; ④ Motor failure - send the motor factory to repair; ⑤ Crankshaft is too tight - disassembly and repair; ⑥ three-phase motor out of phase - repair circuit and switch.
