ChineseIf the car air compressor cannot supply air, it can be detected from the following aspects. The user's pipeline pressure or air storage tank pressure is higher than the lower pressure difference of the machine, the outlet valve of the air compressor is not opened, the intake valve is stuck, and the cylinder Broken diaphragm, failure of relief valve, failure of solenoid valve of empty truck, failure of capacity regulating valve, failure of PLC or controller, leakage of control pipeline, leakage of pressure maintenance valve.
The influence of poor ventilation and heat dissipation in the air compressor station on the machine, the temperature of the rotor outlet rises and the high temperature tripping occurs. cause the motor to be overloaded. Overloading the fan motor. The rise in air outlet temperature causes the load on the dryer to increase. It is recommended that customers add air ducts and exhaust systems. The reason for the abnormal noise of the air compressor is that the connecting rod bush is seriously worn, the connecting rod bolt is loose, the connecting rod bushing is seriously worn, the main shaft is seriously worn or damaged, resulting in impact sound; the belt is too loose, and the grooves of the active and passive belts do not match, resulting in slipping and emptying. Abnormal noise of the compressor; the air compressor does not supply oil immediately after running, and the metal dry friction produces abnormal noise of the air compressor; the fixing bolts are loose; the tightening gear nut is loose, resulting in excessive backlash and abnormal sound of the air compressor; There is a foreign body on the piston crown.
Air compressor abnormal noise fault judgment and elimination method: When the air compressor abnormal noise, check whether the connecting rod bush, connecting rod bushing, main bush is worn, strained or burned, whether the connecting rod bolt is loose, check the main shaft of the air compressor. Check whether the oil passage is unobstructed; it is recommended to replace the severely worn or strained bearing bush, bushing, and main bush, tighten the connecting rod bolt, and use the compressed air oil hole to align the air compressor oil inlet hole; air dredging the main oil passage. When reassembling, pay attention to the spindle bearings.
When the air compressor makes abnormal noises, check whether the grooves of the active and passive pulleys are consistent. If they are inconsistent, replace them and adjust the belt tightness. Check the oil inlet pressure of the lubricating oil and whether the oil pipeline is damaged or blocked. If the pressure is insufficient, immediately adjust, clean and replace the failed pipeline; Whether the air compressor is supplied with oil, if there is no oil supply, a comprehensive inspection should be carried out immediately.
Check whether the fixing bolts of the air compressor are loose and tighten them, which will help alleviate the abnormal noise of the air compressor. Gear-driven air compressors should also check whether the gears are loose or the gears are installed and fitted. If the nut is loose, tighten the nut. If the fit is problematic, it should be replaced.
