Closed cycle degreasing cleaning system of helium diaphragm compressor pipeline

Abstract

The invention discloses a closed cycle degreasing cleaning system of a helium diaphragm compressor pipeline. The closed cycle degreasing cleaning system comprises a first-stage exhaust pipe, a first-stage cooler, a second-stage intake pipe, a first-stage intake pipe, a corrosion resistant centrifugal pump, a liquid inlet ball valve, a liquid containing groove, a liquid outlet ball valve and a second-stage cooler, wherein the first-stage exhaust pipe, the first-stage cooler and the second-stage intake pipe are connected to the position of a first-stage exhaust valve on a first-stage cylinder cover cavity of a compressor, and the second-stage intake pipe passes through the position of a second-stage exhaust valve of the compressor and then is connected to a second-stage cylinder cover cavity in a compressor body; the first-stage intake pipe, the corrosion resistant centrifugal pump, the liquid inlet ball valve, the liquid containing groove, the liquid outlet ball valve and the second-stage cooler are connected to the position of a first-stage intake valve on the first-stage cylinder cover cavity in the compressor body in sequence, and the second-stage cooler passes through the position of the second-stage exhaust valve of the compressor and then is connected to the second-stage cylinder cover cavity in the compressor body; a degreasing agent is added to cleaning liquid in the liquid containing groove. According to the closed cycle degreasing cleaning system, in the condition that an original pipeline of the compressor is connected, the pipeline does not need to be removed, and the inner wall of the pipeline can be quickly cleaned in a degreasing mode without dead angles.

Description

technical field [0001] The invention relates to the technical field of helium diaphragm compressor cleaning, in particular to a closed cycle degreasing and cleaning system for a helium diaphragm compressor pipeline. Background technique [0002] Diaphragm compressor is a volumetric compressor with a special structure, which has the characteristics of large compression ratio, good sealing performance, and the compressed gas is not polluted by lubricating oil and other solid impurities. In view of the characteristics of small molecular weight, easy leakage, high value, and easy pollution of helium, it is the best choice to choose a diaphragm compressor with better airtightness for helium compressors. Since the parts of the diaphragm compressor in contact with the compressed medium are the membrane cavity of the cylinder head and the inner surface of the gas pipeline, it will inevitably be contaminated with a certain amount of oil during manufacturing and test runs. In this way...

Problems solved by technology

This cleaning method not only has low cleaning efficiency, wastes degreasing solvent, and is uneconomical, but also has a large size and complex shape of a single pipeline part of a large diaphragm compressor, which cannot be cleaned thoroughly by the above two methods, which also causes helium gas after installation. contaminate, reduce its purity
