[0002] Hydrogen compressor is an important equipment, which plays an important role in the fields of hydrogen refueling stations and fuel cell vehicles. Hydrogen is usually compressed to high pressure, so a piston compressor with hydrogen as the main transmission medium is needed. Liquid-driven hydrogen compressor uses hydraulic pressure as the driving power source and is widely used in the hydrogen compression industry.

Gas enters the outer cylinder, and the gas enters the air inlet pipe through the filter cylinder. The filter cylinder filters dust and impurities in the gas, and the dust and other impurities filtered out by the filter cylinder fall into the inner side of the bottom cover through the movable hole and the fixed hole in turn. When it is necessary to clean the dust and impurities accumulated in the bottom cover, the strut is rotated to drive the movable disk to rotate, and the movable hole of the movable disk is rotated to be staggered with the fixed hole to close the connection between the fixed hole and the movable hole, and then the bottom cover is rotated to remove and separate it from the bottom end of the outer cylinder, and the dust and impurities accumulated in the filter cylinder and the bottom cover are cleaned, so that the staff can easily disassemble the filter cylinder for cleaning, thereby improving the use effect of the compressor.
