In the field of industrial metallurgy, compressors are used to perform some of the necessary processes in the metallurgical field. The compressor for metallurgy is generally a large-scale compressor, the size of the compressor is large, and the compressor needs to be driven by a high-power supply. If a compressor using a crank mechanism, the crank mechanism generates a side friction force during a reciprocating motion, increasing power consumption of the compressor and increasing wear. If the compressor of the piston mechanism is used, the swing in the process of the back movement can cause the deterioration of the sealing performance, reduce the compression efficiency and influence the production efficiency.

For a small displacement scene, the compression amount is too large or too small due to the compression of the uncertain displacement, and the compression efficiency is reduced.
