Reciprocating compressor

Abstract

The reciprocating compressor of the present invention is composed of a closed container for storing lubricating oil on the bottom surface, a frame assembly for elastically supporting a reciprocating motor and a compression unit in the airtight container, a reciprocating motor mounted on the frame assembly, and a frame assembly connected to the motor. It consists of a compression assembly that compresses the liquid, and a lubricating oil supply assembly that vibrates simultaneously with the frame assembly and pumps the lubricating oil to the compression unit. The lubricating oil supply assembly includes a hydraulic cylinder fixed on the frame and a lubricating oil piston that is dynamically matched with the hydraulic cylinder and whose two ends have different areas from each other. The lubricating oil assembly removes the lubricating oil suction valve and oil discharge valve, so not only the number of parts for the lubricating oil supply assembly is reduced, the cost is reduced, but also the compression caused by the misoperation of the lubricating oil valve during the opening and closing process is prevented. Lack of oil in the unit.

Description

technical field [0001] The invention relates to a reciprocating compressor, belonging to a fluid pressure actuator. Background technique [0002] Generally, the working operation of reciprocating compressors is divided into two methods: driving the motor to make rotary motion to drive the living body to make linear motion to inhale and compress gas, and driving the motor and piston to make linear motion to inhale and compress gas at the same time. [0003] In the prior art, the sectional view of the reciprocating compressor in which the mover and the piston of the driving motor perform linear motion at the same time is as follows: figure 1 shown. This existing reciprocating compressor basically consists of the following parts: the bottom stores lubricating oil, a closed container 10 connecting the suction pipe (SP) and the discharge pipe (DP), a reciprocating motor 20 fixed in the closed container, and a Compression unit 30 for sucking air and compressing gas in the airtig...

AI Technical Summary

Problems solved by technology

[0012] However, the above-mentioned conventional reciprocating compressor must be equipped with the lubricating oil suction valve 61c, the lubricating oil discharge valve 61d, and the lubricating oil spring 61e elastically supporting the lubricating oil piston 61b. The installation fee is increased, which eventually leads to an increase in cost

[0013] In addition, due to the small diameter of the lubricating oil suction valve 61c, it is not only inconvenient to process, but also difficult to install. At the same time, it may be stuck on the lubricating oil spring after installation, hindering the smooth lubricating effect.
