Compressor Main Spare Part Structure Instruction
The basic part mainly includes: crank case, crankshaft, connecting rod, cross head, its role is to connect the foundation and the cylinder part and transmit power.

Connecting Rod

The connecting rod is divided into two parts: connecting rod body and connecting rod big end bush cover, which are connected into a whole by two tensile bolts. The connecting rod big end bush is split type. The material of bush back is carbon steel. The bush surface is bearing alloy. The two ends are flanged for axial positioning. The inner surface of big end hole is inlaid with cylindrical pin, which is used for radial positioning of big end bush to prevent the Bush from rotating. The connecting rod small end and small end bush are integral type, and the bush material is tin bronze. The screw hole at the big-end tile cover of the connecting rod is used for lifting when disassembling, and the eye bolt should be removed after assembly.

Crosshead hydraulic connection fastening device

The hydraulic connecting and fastening device is used for connecting the piston rod and crosshead body, which is mainly composed of the connecting device and the fastening device.

Principle: after connecting the piston rod and crosshead by connecting the fastening device, inject 150MPa pressure oil into the pressure body of the fastening device with the random tool of manual high pressure oil pump. By using the incompressible property of liquid, push the piston, force the end of piston rod to produce elastic tensile deformation, and then lock the lock nut, release the oil pressure, so as to achieve the pre tightening force required for connection.
