I believe that many users will often encounter the abnormal noise of the screw air compressor host, so how to deal with it? Next, we will introduce in detail the solution to the abnormal noise and whining sound of the air compressor main unit.
Fault phenomenon: The main engine of the air compressor vibrates and makes a lot of noise. During operation, it sometimes emits metal collisions, impacts, uniform knocking sounds, friction and whistling sounds, etc.
Analysis of the causes of abnormal noise from the air compressor host:
① The belt is too loose, and the grooves of the active and passive belts are too large, causing slipping and whistling sounds; (belt drive type)
② When the screw air compressor is running, the oil supply is not timely, causing the yin and yang screws to directly engage without lubricating oil, causing metal dry friction to cause whistling;
③The foundation or inlet filter fixing bolts are loose;
④ If the fastening gear nut is loose, the tooth gap will be too large to produce a knocking sound;
⑤ The intake valve is not closed tightly, the air leakage is large, and the intake valve backstop vibrates.
⑥ If something falls into the main unit, the yin and yang screws will get stuck and collide, causing a whistling sound;
⑦The gap between the male and female screws and the end faces of the bearings is too large;
⑧The main engine bearing is damaged.
Solution to abnormal noise from the air compressor host:
①Replace the belt and adjust the belt tightness;
② Check the oil level, replace the Atlas oil filter, and add oil to the air compressor main engine. Make sure that the oil does not reach 3/4 of the rotor.
③ Check and tighten the bolts, and re-align the air compressor;
④ Check the vibration condition and confirm that the fastening gear nut is loose and stop repairing;
⑤Adjust the position of the air intake butterfly piece;
⑥, ⑦, ⑧ Solutions: Carry out main engine overhaul.
The above is the editor’s personal opinion on the abnormal noise of the screw air compressor host. I hope it will be helpful to you when choosing an oil-free air compressor.
