Description

Air compressor

Technical Field

The application relates to the technical field of air compressors, in particular to an air compressor.

Background

The novel piston ring structure of the air compressor in the prior art is widely applied to the piston type reciprocating air compressor of the non-induction motor, the forming is simple, the material is made of polytetrafluoroethylene plastic, the forming is similar to a bowl, the simple structure enables air to be unnecessary released in the compression process, compressed air is unbalanced, the service life of the machine is greatly reduced, the maintenance cost of the machine is improved, and the service life of the machine is influenced.

SUMMERY OF THE UTILITY MODEL

Therefore, there is a need for an air compressor, which can release the redundant air in the cylinder by providing a circular hole on the piston ring, so that the air in the cylinder is balanced and the operation process of the machine is smooth.

The application provides an air compressor, including the piston ring, be provided with a round hole along the circumferencial direction at least on the piston ring main part.

In the above scheme, through set up the round hole on the piston ring for the rational in infrastructure optimization of appearance of piston ring can release the unnecessary gas in the cylinder, makes the gas in the cylinder reach the balance, and it is smooth and easy to make the machine operation process, improves the life factor of machine, reduces the maintenance cost of machine.

In some embodiments, the angle between the inner side wall of the circular hole and the horizontal end surface of the piston ring is 45 degrees.

In some embodiments, the circular hole has a diameter of 1mm to 2 mm.

In some embodiments, the piston ring is of one-piece construction.

In some embodiments, the piston ring further comprises a pressing plate and a fixing screw, wherein the pressing plate is pressed on the surface of the piston ring, and the fixing screw penetrates through a connecting hole in the pressing plate to be connected with a connecting rod, so that the piston ring is connected with the connecting rod.

In the scheme, the piston ring is arranged at the installation position of the connecting rod, and is pressed by a pressing plate; and the piston ring is locked by the fixing screws, and then the shaping effect is further achieved by the friction with the inner wall of the cylinder, so that the piston ring can smoothly move in the cylinder.
