Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a compressor oil circuit automatic circulation device for a hydrogen refueling station, which solves the problem in the above-mentioned background technology that when the piston expands and contracts in the existing compressor, the oil circulates along with it to inflate the diaphragm. , but the circulating flow of oil is easy to carry residues. When the oil containing residues flows and bulges the diaphragm, it is easy to cut the diaphragm due to the residues, resulting in leakage.

Abstract

The invention discloses a compressor oil way automatic circulating device for a hydrogen refueling station, and relates to the technical field of hydrogen refueling stations, in particular to a compressor shell and an oil filtering assembly, air inlet valves are arranged on the two sides of the top of the compressor shell, a transmission belt is connected to the outer portion of an initial wheel in a sleeving mode, and the oil filtering assembly is connected to the bottom of an oil inlet pipe. A liquid passing column is fixed to the bottom of the liquid pressing supporting rod, a stable silk screen is fixed to the lower surface of the molecular film, and a threaded pipe is arranged at the bottom of the oil filtering pipe body. According to the compressor oil way automatic circulating device for the hydrogen refueling station, when the telescopic piston works, the molecular film ascends and descends along with the telescopic piston, oil liquid to enter the compressor shell is filtered through the molecular film, residues are separated out, and the situation that the residues enter the compressor shell to cut a diaphragm is prevented; meanwhile, the lower surface of the molecular film can be washed when the molecular film ascends and descends, pores in the surface of the molecular film can be kept unobstructed and prevented from being blocked by residues, and long-time filtrate operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of hydrogenation stations, in particular to an automatic circulation device of a compressor oil circuit for a hydrogenation station. Background technique [0002] The hydrogen storage of the hydrogen refueling station requires the use of a compressor. The compressor compresses the hydrogen so that the hydrogen storage tank can store more hydrogen. The working principle of the compressor is: the hydrogen enters the compressor through the intake valve and passes through the piston. The expansion and contraction absorb or discharge the oil, so that the diaphragm swells up and down, so that the hydrogen is discharged from the exhaust valve and pressed into the hydrogen storage tank. [0003] In the existing compressor, when the piston expands and contracts, the oil circulates with it to inflate the diaphragm, but the circulating oil easily carries residues. When the oil containing the residue flows and inflates ...
