Pump body structure of rotating cylinder piston compressor and rotating cylinder piston compressor

Abstract

The invention provides a pump body structure of a rotating cylinder piston compressor and the rotating cylinder piston compressor. The pump body structure of the rotating cylinder piston compressor comprises a cylinder sleeve, a cylinder and two matching structures, wherein the cylinder sleeve is provided with a cylinder installing cavity and an exhausting port communicating with the cylinder installing cavity; the cylinder is rotationally installed in the cylinder installing cavity; the end face of the cylinder is provided with a first matching portion; the two matching structures are correspondingly arranged at the two ends of the cylinder, and are connected to the cylinder sleeve; the first matching portion has the tendency of moving towards the corresponding matching structure under the pressure effect of the exhausting port position; the position, corresponding to the first matching portion, on one side face, facing the cylinder, of each matching structure is provided with a second matching portion; and the second matching portion of at least one matching structure is provided with at least one pressure groove, and the pressure groove is suitable for introducing pressure oil and / or pressure gas so that the tendency that the first matching portion moves towards the corresponding matching structure can be reduced or eliminated. Due to the pump body structure of the rotatingcylinder piston compressor and the rotating cylinder piston compressor, the inclination degree of the cylinder can be reduced or it is avoided that the cylinder inclines.

Description

technical field [0001] The invention relates to the technical field of compression equipment, in particular to a pump body structure of a rotary cylinder piston compressor and the rotary cylinder piston compressor. Background technique [0002] The rotary cylinder piston compressor is a compressor with a new structure. In essence, it adopts a cross slider structure principle and combines the main structure of the piston compressor with the main structure of the rotary compressor to obtain a compressor. . In the existing rotary cylinder piston compressor, it includes a rotating shaft, a piston sleeved outside the rotating shaft, a cylinder sleeved outside the piston, and two matching structures respectively located at both ends of the cylinder; refer to figure 1 , O1 is the center of the rotating shaft, O2 is the center of the cylinder, e is the distance between the centers of the circles, and the square is the center of mass of the piston. When the rotating shaft rotates, ...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned rotary cylinder piston compressor, the cylinder liner is usually provided with a suction port and an exhaust port. Due to the low-pressure intake and high-pressure air output, the pressure at the exhaust port is usually higher than the pressure at other positions, so that As a result, a horizontal force will be applied to the cylinder at the exhaust port. When the horizontal force received by the cylinder constitutes a moment, the cylinder will tilt, thereby increasing the friction loss between the cylinder and the matching structure, affecting the structure of the pump body and the compressor.
