Butiran Kes

Answer: (1) Fault phenomenon. The main engine of the air compressor vibrates and makes loud noises. Sometimes it will make metal impact sounds, uniform knocking sounds, friction whistling sounds, etc. during operation.

(2) Cause analysis.

1) The belt is too loose, and the main and passive belt grooves do not match, causing slippage and whistling;

2) The air compressor is not immediately oiled after operation, and metal dry friction causes whistling;

3) The fixing bolts of the anchor or inlet filter are loose;

4) The nuts of the fastening gear are loose, causing excessive tooth clearance and knocking sounds;

5) The intake valve is not closed tightly, resulting in large air leakage, and the intake check valve vibrates.

(3) Elimination methods

1) Replace the belt;

2) Check the oil level and replace the oil filter;

3) Check and tighten the bolts and realign the air compressor;

4) Check the vibration and confirm that the fastening gear nut is loose and repair it;

5) Adjust the intake valve position.
