Many users will often encounter abnormal noise and humming noise from the main engine of the screw air compressor. How to deal with it? Next, we will introduce in detail the solution for abnormal noise and humming noise from the main engine of the air compressor.
Fault phenomenon: The main engine of the air compressor vibrates and makes loud noises. Sometimes metal collisions, impacts, even knocking sounds, friction whistling sounds, etc. are emitted during operation.
Cause analysis of abnormal noise from the main engine of the air compressor:
① The belt is too loose, and the matching of the main and passive belt grooves is too large, causing slippage and whistling sounds; (belt drive type)
② The oil supply of the screw air compressor is not timely during operation, so that the yin and yang screws are directly engaged without lubricating oil, and the metal dry friction produces whistling;
③ The fixing bolts of the anchor or the inlet filter are loose;
④ The fastening gear nut is loose, causing the tooth gap to be too large and produce a knocking sound;
⑤ The intake valve is not closed tightly and the leakage is large, and the intake valve is vibrating when it is not reversed.
⑥ Something falls into the main engine, causing the Yin and Yang screws to collide and produce a whistling sound;
⑦ The gap between the Yin and Yang screws and the bearing end faces is too large;
⑧ The main engine bearing is damaged.
Air compressor main engine abnormal noise treatment plan:
① Replace the belt and adjust the belt tightness;
② Check the oil level, replace the Atlas oil filter, and add oil to the main engine of the air compressor. Do not let the oil bubble to 3/4 of the rotor.
③ Check and tighten the bolts, and re-align the air compressor;
④ Check the vibration condition, confirm that the fastening gear nut is loose and stop repairing;
⑤ Adjust the position of the air intake butterfly;
⑥, ⑦, ⑧ treatment methods: stop the main engine overhaul.
