Problems solved by technology

However, the piston and the slide plate are integrated, which is difficult to process; the reciprocating space of the slide plate needs to be reserved inside the cylinder, which makes the cylinder bulky and easy to deform; due to structural limitations, the compression heat and friction heat generated by the machine cannot be quickly Discharge, poor heat dissipation performance

Abstract

The invention relates to the air compression, fluid conveying and the evacuation fields, in particular to a rotary compression machine with a translational piston; the integral translational rotary compression device comprises a cylinder body, a crankshaft, a crankcase, an electromotor component, a sliding plate, a translational piston; one end of the crankshaft is provided with an eccentric rotor; the rotary center of the eccentric rotor is concentric with the cylinder body and movably arranged on the eccentric rotor; the lateral surface of the eccentric rotor is tangent with the inner lateral surface of the cylinder body, so as to form a crescent-shaped operation cavity; one end of the sliding plate is hinged on the inner wall of the cylinder body; a sliding plate groove is arranged on the translational piston in the radial direction; the other end of the sliding plate is extended to the sliding plate groove through the operation cavity; the operation cavity is divided into an expansion cavity and a compression cavity by the sliding plate; a suction port and a discharge port are respectively on the expansion cavity and the compression cavity; the electromotor component is arranged on the right end of the cylinder body; the electromotor component includes a rotor and a stator; the other end of the crankshaft is threaded through the crankcase; the crankshaft is extended rightwards to be fixedly connected with the rotor. The rotary compression machine with a translational piston has the advantages of simple structure and high operation efficiency.

Description

technical field [0001] The invention relates to the fields of gas compression, fluid delivery and vacuum pumping, in particular to a rotary compression machine with a translational piston. Background technique [0002] Gas compressors, fluid pumps and vacuum pumps are important general purpose compression machinery. At present, rolling piston compression machinery and rotor compression machinery, as representatives of the second generation of compression machinery, both have a crescent-shaped working chamber; the crescent-shaped working chamber is separated into an expansion chamber and a compression chamber by a slide plate; The moving piston) changes the volume of the expansion chamber and the compression chamber to realize the suction (liquid) and exhaust (liquid) of the compression machine. However, there is a problem in these two compression machines, that is, the sliding plate extends into the working chamber to isolate the expansion chamber and the compression chambe...
