SU1756638A1 - Radial seal of rotary-vane compressor - Google Patents

Abstract

The invention - separation plates (2) are placed in the radial slots of the rotor (3) with the possibility of reciprocating movement and contact with the inner surface of the housing (1). The sealing inserts (4) are located along the perimeter of the plates (2). On the end surface of the plates (2) made longitudinal grooves. The insert (4) is made of an elastic material and in the cross section has the shape of a split ring, the ends of which are rigidly fixed in the grooves. The liner surfaces (4) are coated with an anti-friction material. 2 hp f-ly, 2 ill.

Description

The invention relates to the field of power engineering, in particular to compressor engineering.

It is known to seal a working plate of a stepper air motor, which contains a cylinder with upper and lower covers, forming an engine casing R, an output shaft and a fixed partition are installed in the working chamber R. A propellant (working plate) is attached to the shaft. Seals are mounted on the partition and propellant to reduce leaks, and the liner is made of non-metallic material.

A disadvantage of the known construction is the reduced tightness of the seal with the liners, due to the lack of sufficient elasticity of the liner material.

The aim of the invention is to increase the efficiency of compaction by reducing leakage.

Expected technical and economic effect of the proposed technical solution

lies in the possibility of increasing the technical characteristics of the compressor.

This goal is achieved by the fact that in a radial seal of a rotary-blade compressor containing separation plates placed in the radial grooves of the rotor with the possibility of reciprocating movement and constant contact with the inner surface of the housing, and sealing liners on the end surface of the plate are longitudinal grooves, the liner is made of an elastic material and in the cross section has the shape of a cut ring, the ends of which are rigidly fixed in the grooves, while the liner is ying of st§li and the liner surface is provided with a coating of antifriction material.

FIG. 1 shows a general view of the radial compaction of a rotary-plate compressor; in fig. 2 shows section A-A in FIG. one.

Radial-sealing rotary-flattened compressor having a housing 1 containing separation plates 2, placed in the radial grooves of the rotor 3 with the possibility of return and forward movement and constant contact with the inner surface of the housing 1 and sealing liners 4, and the liner 4 is made of elastic steel and in cross section has the form of a split ring, the ends of which are rigidly fixed in the grooves. The surface of the liner 4 is provided with a coating of antifriction material.

The sealing operation consists in the possibility of elastic deformation of the insert -4 in the contacting surface with the surfaces of the housing 1.
