Diaphragm compressor gas side leakage guide hole device

Abstract

The invention discloses a diaphragm compressor gas side leakage guide hole device. The device comprises a gas disc and an oil disc of a diaphragm compressor, a diaphragm and a diaphragm head leakage gathering groove are arranged between the gas disc and the oil disc, a gas disc sealing ring is arranged on the contact face between the gas disc and the diaphragm, a gas disc leakage gathering groove is formed in one side of the gas disc, and the gas disc leakage gathering groove communicates with a gas disc leakage connector through guide holes. By arranging the gas disc leakage gathering groove and the guide holes, when the gas disc sealing ring generates leakage, pressure is directly released to the gas disc leakage connector through the gas disc leakage gathering groove and the guide holes, the position can be directly discharged to a safety position or returned to a gas inlet pipeline of the compressor, leaked gas is prevented from going to a diaphragm head detection connector, and therefore the influence of false alarm and shutdown generated by accidental leakage of the gas disc sealing ring on production is avoided, and the maintenance period of a diaphragm head of the diaphragm compressor is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of diaphragm compressor equipment, and in particular relates to a gas side leakage guide hole device of a diaphragm compressor. Background technique [0002] Diaphragm compressors on the existing market generally adopt the method of 3 rings and 1 groove for diaphragm head seal, that is, 1 gas pan seal ring, 1 oil pan seal ring, 1 outer seal ring and 1 leakage converging groove. When any one of the gas disc sealing ring, oil pan sealing ring or oil-gas side diaphragm is damaged, the pressurized gas or pressurized hydraulic oil will leak, which will be collected at the detection port of the membrane head through the leakage converging groove, and the pressure will The instrument detects leakage faults, alarms or emergency shutdowns in time. [0003] The defect of the existing technology is that when the compressor runs for a long time or the operating condition is unstable, the high-temperature and high-press...

AI Technical Summary

Problems solved by technology

[0003] The defect of the existing technology is that when the compressor runs for a long time or the operating condition is unstable, the high-temperature and high-pressure gas (especially small molecule gas, such as hydrogen) in the membrane head can easily penetrate the gas disc sealing ring , Occasional gas leakage occurs, causing the pressure instrument for leakage detection to alarm and shut down

When the membrane head of the compressor was disassembled and inspected, it was found that the diaphragm and the sealing ring were not obviously damaged, but the downtime for maintenance caused a lot of production shutdown losses, and the disassembly of the membrane head caused a lot of labor hours.
