Screw compressor body is divided into two types, one is belt drive type and the other is direct drive type. Among them, the belt drive type is more suitable for the compressor with a power of about 22KW, which is driven by two pulleys made according to the speed ratio. The direct drive type is 1 coupling, which combines the power supply with the main engine. The worm compressor can directly drive the worm to rotate, while the twin-screw compressor needs to add another speed-increasing gear to increase the rotation speed of the main rotor.
