The application relates to the technical field of diaphragm compressors, in particular to a
diaphragm compressor oil cavity structure and a
diaphragm compressor. The
diaphragm compressor oil cavity structure comprises the following: an oil side membrane head is provided with an
oil distribution disc and an oil cylinder sleeve; a
piston is arranged in the oil cylinder sleeve; a diaphragm is arranged between the
oil distribution disc and the gas distribution disc; a space between the diaphragm and the
piston constitutes an oil cavity; a flow
inducer is arranged in the oil cavity between the
oil distribution disc and the oil cylinder sleeve, and the flow
inducer is suitable for guiding hydraulic oil to flow from the periphery of the flow
inducer so as to block the hydraulic oil from directly impacting the central area of the diaphragm. According to the application, the flow inducer is arranged in the oil cavity, the hydraulic oil driven by the
piston first passes through the flow inducer to change the flow field characteristics, the flow of the hydraulic oil after the flow induction is more uniform, and then the diaphragm is driven to deform through the oil distribution disc; the hydraulic oil after the flow induction no longer impacts the central area of the diaphragm, the deformation environment of the diaphragm is improved; the
impact force of the hydraulic oil on the central area of the diaphragm is eliminated, the service life of the diaphragm is prolonged, and the efficiency of the diaphragm compressor is improved.
