Diaphragm compressor oil side cylinder

Abstract

The invention discloses a diaphragm compressor oil side cylinder. The diaphragm compressor oil side cylinder comprises a cylinder body and thin film, the bottom face of the axis of the cylinder body is inward provided with a cylinder sleeve hole, the upper end face of the cylinder body is inward provided with an inner sunken hook face, the upper end face of the cylinder body is inward provided with a plurality of radiation milling grooves in an annular array, the inner end of each radiation milling groove is communicated with the cylinder sleeve hole, the upper end face of the cylinder body isinward provided with a plurality annular grooves, the side face of the cylinder body is inward provided with a pressure regulating valve mounting hole, a pressure tapping point and the like respectively, the pressure regulating valve mounting hole and the pressure tapping point are both communicated with the outer ring of the annular groove, the thin film is arranged on the upper end face of thecylinder body, and the movable range of the thin film is in the inner sunken hook face. The diaphragm compressor oil side cylinder has the advantages that the oil use amount is reduced, the oil flow velocity is improved, and therefore, the efficiency of a diaphragm compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of diaphragm compressors, in particular, the invention relates to an oil side cylinder body of a diaphragm compressor. Background technique [0002] At present, diaphragm compressors at home and abroad mostly adopt the method of radiating oil holes on the cylinder body to achieve uniform distribution and delivery of oil, and even some backward oil distribution plate structures are still used (the structure of the oil distribution plate has shortcomings) There are many, and have been basically deprecated). However, the structure currently in use has some shortcomings that still need to be improved. The detailed description is as follows: the radial oil hole needs to be installed with a process screw plug, and a lot of oil holes must be drilled on each cylinder to distribute the oil evenly to the curve of the cylinder. Every part, and the useless parts need to be plugged with installation technology, which in...

Problems solved by technology

[0002] At present, diaphragm compressors at home and abroad mostly adopt the method of radiating oil holes on the cylinder body to achieve uniform distribution and delivery of oil, and even some backward oil distribution plate structures are still used (the structure of the oil distribution plate has shortcomings) Many, have been basically abandoned)

However, the structure currently in use has some shortcomings that still need to be improved. The detailed description is as follows: the radial oil hole needs to be installed with a process screw plug, and a lot of oil holes must be drilled on each cylinder to distribute the oil evenly to the curve of the cylinder. Every part, and the useless parts need to be plugged with installation technology, which increases the risk of oil leakage; the oil consumption is large, and the current structure uses large oil holes and a large number, so the oil consumption is large and the oil is large It is not easy to improve the efficiency; the processing volume is large, and different numbers of oil holes need to be drilled according to different cylinder diameters; the number of ring grooves is large, the processing procedures are many, and the groove width is the same inside and outside, not necessarily suitable for various pressures; for extreme pressure or medium Situations prone to various problems or instability
