Abstract

The invention discloses a novel diaphragm compressor. The novel diaphragm compressor comprises a cylinder body, a first-stage cylinder, a second-stage cylinder and a third-stage cylinder. The first-stage cylinder, the second-stage cylinder and the third-stage cylinder are all fixedly installed on one side of a base, a cylinder head is arranged on one side of the cylinder body, an oil overflow valve is arranged on one side of the cylinder head, and an oil supplementing valve is arranged on the other side of the cylinder body. One side of the cylinder body is provided with a cylinder cover, andone side of the cylinder cover is provided with an air inlet valve. According to the novel diaphragm compressor, when liquid is brought into the air cylinder of the compressor in the compression process, the liquid is discharged by arranging a liquid discharging valve, and the situation that the liquid is forced by a piston in the air cylinder to generate strong impact and the machine body vibrates violently and thus is damaged is prevented. By adding the cylinder parts, the total compression ratio of the diaphragm compressor can be effectively improved to meet the requirement of high-pressureoutput. The cylinder cover is made of L-shaped stainless steel and is good in hydrogen embrittlement resistance. The upper portion of the cylinder cover is provided with a flange for connection, thestructure of the cylinder body is more stable and firmer, and the effect on the high-pressure or ultrahigh-pressure diaphragm compressor is particularly outstanding.

Description

technical field

[0001] The invention relates to the technical field of compressors, in particular to a novel diaphragm compressor. Background technique

[0002] Diaphragm compressors are determined by their structural characteristics. It is widely used in compressing and conveying various high-purity gases, precious and rare gases, poisonous and harmful gases and corrosive gases. As an irreplaceable volumetric compressor, it will be Continuous improvement will have a wider range of applications.

[0003] As a special type of compressor, the diaphragm compressor has advantages that other types of compressors do not have, but it also has two basic disadvantages: the size and specification of the diaphragm head are limited; the process gas must be clean, free from solid particles or dust pollution , otherwise the diaphragm is very easy to break, and the single-stage compression ratio is controlled to avoid liquefaction of components in the compression cavity. During the oper...
