Air compressor overheat fault phenomenon ： The air compressor exhaust temperature is too high . The pressure relief valve or unloading valve does not work, causing the air compressor to overheat . Serious leakage of the air braking system leads to overheating of the air compressor . Insufficient oil supply at the running part and cylinder pulling .

Air compressor overheat fault diagnosis and troubleshooting ： Check the pressure relief valve assembly during air inlet unloading , Clean and remove stuck parts or replace defective parts . During exhaust unloading, check the unloading valve for blockage or stagnation, and clean, repair or replace the invalid parts , Effectively eliminate the overheat fault of air compressor ; Check the brake system components and pipelines ; Poor lubrication between piston and cylinder liner 、 Too small clearance or cylinder pulling can cause overheating , In this case, check 、 Repair or replace the failed parts .

In the process of daily use of the air compressor , The air compressor often makes abnormal noise , for example ： Metal impact , Uniform knocking sound , Abnormal noise fault of the air compressor due to friction whistle .

 

Cause of abnormal noise of air compressor ： The connecting rod bush is severely worn , The connecting rod bolts are loose , The connecting rod bushing is severely worn , The main shaft is seriously worn or damaged to produce impact sound ; The belt is too loose , Lord 、 The non-conforming groove of the passive belt causes slipping and abnormal noise of the air compressor ; There is no oil supply immediately after the air compressor is running , The air compressor makes abnormal noise due to metal dry friction ; The fixing bolts are loose ; The fastening gear nut is loose , Cause excessive backlash to produce abnormal noise and knocking sound of air compressor ; There is foreign matter on the piston crown .

Air compressor abnormal noise fault diagnosis and troubleshooting ： When the air compressor rings , Check the connecting rod bush 、 Connecting rod bushing 、 Whether the main bearing bush is worn 、 Strain or burn , Check whether the connecting rod bolts are loose , Check whether the main oil passage of the air compressor is unblocked ; It is recommended to replace the severely worn or strained bearing bush 、 bushing 、 Main bearing bush , Tighten the connecting rod bolts , Align the compressed air oil hole with the oil inlet hole of the air compressor ; Air dredges the main oil passage . When reassembling , Pay attention to the main shaft bearing .

 

When the air compressor rings , Check the master 、 Whether the groove type of the driven pulley is consistent , If not, please replace , And adjust the belt tightness .

Check the lubricating oil inlet pressure 、 Whether the oil pipeline is damaged 、 jam , If the pressure is insufficient, it should be adjusted immediately 、 clear 、 Replace the failed pipeline ; Check the oil quality and impurity content of the lubricating oil , Compare with the standard used , Replace immediately ; Check whether the air compressor supplies oil , If there is no oil supply, check immediately .
