Come and learn about the three transmission modes of screw air compressors


1. Transmission belt

Engineers should always check the wear and tightness of the transmission belt. If the tightness is not adjusted properly, it will aggravate wear or breakage. When checking the tightness of the belt, you can press the middle part of the two pulleys with a force of 40N with your thumb. Generally, it is better to sink 10-15mm.

When checking belt wear, in addition to checking the wear and aging of its working surface, it is also necessary to check that the outer plane of the V-belt should be more than 1-2mm higher than the edge of the pulley. Otherwise, the belt has reached the wear limit and must be replaced.

When replacing, be sure to select good quality belts of the same model and replace them in groups. Otherwise, the belt will be damaged due to uneven force when transmitting power.

2. Gear transmission

The transmission mode is that the cylinder block of the air compressor is docked with the engine block or gear box, and is directly driven by the gear of the engine.

If it is found that the air compressor is malfunctioning and needs to be disassembled and repaired, be sure to check the gear wear and meshing clearance, and check the tightening state of the gear, and fasten, adjust or replace it in time .

3. Coupling drive

Some of the air compressors with coupling transmission output power at the rear of the fuel injection pump, and some are connected with the engine timing gear box.

During inspection, you can check whether the connecting plate is reliably connected in a static state, and whether there is obvious looseness when moving it by hand. When running at low, medium and high speeds, there should be no abnormal noise in the coupling and bearings.
