Abstract

The invention relates to the technical field of piston compressor assembling parts, in particular to a spiral fixed pattern fastening connecting device for a piston compressor. The spiral fixed pattern fastening connecting device comprises a crosshead body, a crosshead nut positioned at the upper end of the crosshead body, and a longitudinal piston rod fixed to the upper end of the crosshead nut.Based on the original fastening of the spiral fixed pattern fastening connecting device for the piston compressor, a fastening steel plate with a limiting groove is additionally arranged to cooperatewith fixation, and an external thread connecting sleeve and the fastening steel plate are fixedly connected by utilizing threaded connection, so that the problem that the piston rod of a small and medium size compressor is likely to loosen on the condition that the reciprocating inertial force is excessively large, the working time is long and the working strength is high is avoided and the safetyand reliability of continuous operation of the compressor are effectively improved.

Description

Technical field [0001] The invention relates to the technical field of assembling parts of a piston compressor, in particular to a screw fixing type fastening connection device for a piston compressor. Background technique [0002] In the connection between the connecting rod and the piston rod in a reciprocating compressor, a crosshead is often used to over-connect. The piston rod is connected to the connecting rod through the crosshead so that the piston rod will not be subjected to the side pressure caused by the connecting rod. In this way, the friction between the piston and the cylinder is minimal. In addition, the crosshead and piston rod can only move axially, which can make full use of the volume of the cylinder, and the method of controlling the lubricating oil is relatively simple, which increases the efficiency of the compressor. [0003] Although there are many ways to connect the piston rod and the crosshead in reciprocating compressors, most of the connection method...
