Abstract

The invention discloses a compressor connecting rod parallelism measuring instrument, which comprises a main rod adjusting part, an auxiliary rod, an indicating part and a fixing part; the main rod part includes a main rod, one end of the main rod is sleeved on It is connected with the positioning rod; one end of the auxiliary rod is inserted into the main rod, and the other end is extended outside the adjusting part of the main rod and connected with the indicating part; the fixing part is arranged on the outside of the main rod to fix the connection between the main rod and the auxiliary rod relatively mobile. The main rod adjustment part also includes a positioning rod; the positioning rod is provided with a measuring fixed point projection. The measuring instrument has the advantages of simple structure, low manufacturing cost, high measuring precision, reduced labor intensity and improved working efficiency.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a parallelism measuring instrument for connecting rods of a compressor. Background technique [0002] The reciprocating compressor has a history of more than 150 years since its inception, especially in modern petrochemical enterprises, large-scale power enterprises, and super-large coal mine industries. Tens of thousands of KW, the outlet pressure of the compressor can be designed to reach several thousand Mpa. As one of the important parts of the compressor, the connecting rod of the compressor plays the role of converting the powerful power transmitted by the motor from rotary motion to linear reciprocating motion through the coupling, crankshaft, and connecting rod, so that the cross of the compressor The head, piston rod, piston, support ring, expansion ring, and inlet and outlet valves move back and forth hundreds of times per minute in the cylinder, and finally reach the entire p...
