Reciprocating type oil-free piston machine cylinder

Technical Field

The utility model belongs to the technical field of mechanical die design, specifically say, relate to a reciprocating type does not have oily piston engine cylinder.

Background

The reciprocating piston machine is a piston machine with the largest use amount at present due to high efficiency, easy maintenance and long service life. However, the common reciprocating air compressor oil-free piston engine cylinder and the common reciprocating air compressor oil-containing piston engine cylinder are respectively opened, and the universality and the economy are poor, so that the problems of cost increase and delay of delivery are caused. In order to solve these problems, people transform oil-lubricated reciprocating air compressors into oil-free reciprocating air compressors. However, the oil-free lubrication reciprocating air compressor used at present is constructed by opening the die again, so that the manufacturing cost is increased. Therefore, how to solve the problems existing in the prior art is a problem which needs to be solved urgently by the technical personnel in the field.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a reciprocating type does not have oily piston machine cylinder, the problem that the follow oil lubrication reciprocating air compressor machine that exists among the main prior art of solving reforms transform into the production of oil-free reciprocating air compressor machine.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the cylinder of the reciprocating oil-free piston engine comprises a piston cavity and a packing cavity, wherein the piston cavity and the packing cavity are provided with an inner wall, a middle wall and an outer wall, the piston cavity and the packing cavity further comprise a water cavity formed by wrapping the inner wall and the middle wall, and an air cavity formed by wrapping the middle wall and the outer wall, wherein cooling water flowing in the water cavity rapidly cools air in the air cavity and generates friction work required by the work of the cylinder during compression.

Further, the water cavity comprises a water inlet and a water outlet which are arranged on the surface of the middle wall, and a water chamber which is communicated with the water inlet and the water outlet and is used for accumulating cooling water.

Further, the water cavity also comprises a water outlet standby port arranged on the surface of the middle wall.

Further, the air cavity comprises an air inlet and an air outlet which are formed in the outer wall, wherein the air inlet and the air outlet are oppositely arranged on two sides of the piston cavity.

Specifically, the air inlet of the piston cavity is opposite to the air inlet and is also communicated with a standby oil injection port.

Compared with the prior art, the utility model discloses following beneficial effect has:

(1) the utility model discloses a to original cylinder improve, through setting up water cavity and air cavity, the friction work that the gas that utilizes flowing cooling water in the water cavity to get into from the air inlet produced when cooling gas compresses uses of cylinder to can make the cylinder normally work. Adopt oilless formula cylinder to have avoided using lubricating oil polluted environment and the emergence that produces the circumstances such as internal combustion, explosion, and the utility model discloses only improve cylinder inner structure, consequently can not influence the corollary equipment of cylinder. And the utility model discloses still reserve and have reserve oiling mouth to satisfy the cylinder work demand under the different operating mode conditions.
