Installation method of large reciprocating compressor

The invention discloses a large reciprocating compressor installation method, in the reciprocating compressor installation process, the levelness of a reciprocating compressor is measured through a plurality of measuring devices, and any measuring device comprises a bottom plate which is horizontally clamped at the top of a to-be-measured part of the reciprocating compressor through an elastic clamping belt; the two leveling columns are fixedly arranged at the top of the bottom plate, and the interior of each leveling column is filled with mineral oil refined liquid; the base is fixedly connected with the two leveling columns, a cavity is formed by the base and the cover body, and the cavity is filled with mineral oil refined liquid and bubbles capable of freely moving in the mineral oil refined liquid. The reciprocating compressor is leveled through mutual cooperation of the leveling column and the bubbles in the cavity, the problems that the reading time is long and the construction efficiency is affected d
