Description

Tool for disassembling and assembling connecting rod in vertical compressor

Technical Field

The utility model discloses a connecting rod dismounting tool, belongs to the technical field of vertical compressors, and particularly relates to a connecting rod dismounting tool in a vertical compressor.

Background

The main function of the vertical compressor cross head is to connect the piston and the connecting rod and to play a guiding role. The cross head transmits the rotary motion of the crankshaft to the piston through the connecting rod, so that the rotary motion is converted into reciprocating linear motion in the slideway, and the piston is pushed to do work.

In a vertical compressor, the functions of the crosshead include:

the connecting function is that the cross head connects the piston and the connecting rod, and the rotary motion of the crankshaft is transmitted to the piston through the connecting rod, so that the reciprocating motion of the piston is realized.
