CZ-0.41/200A Horizontal Navy Marine High Pressure Water Cooled Air Compressor

Start the prime mover and the compressor crank begins to run, driving the step piston to move up and down. Each working volume begins to shorten in proper order and recycle with variation. The air is admitted in the compressor from the atmosphere via filter cap and compressed in three cylinders successively as to achieve desired final pressure. Air after each-stage compression shall be cooled and then proceed into next-stage cylinder working volume for further compression. Finally, the compressed air is charged in the cylinder after oil-water separation via the separator.

Steel casting crankcase is used to support the crank and fix first-stage and second-stage cylinders. There is a bearing hole both in the front and back of the crankcase as to fix the end caps. Inside the end caps, it is mounted with tapered roller bearings as to support the crank. It is set with a spacer to adjust the axial clearance of the crank between the end cap and crankcase hole. In addition, there is a sealing ring mounted in the front end cap (at the side of shaft coupling) as to prevent the lubricating oil from effusion along the shaft.
