Description

A kind of detachable Rotary Compressor

Technical field

This utility model is related to Compressor Technology field, more particularly to a kind of detachable compressor.

Background technology

Compressor is a kind of machinery by gas compression lift gas pressure, can be applicable to (cold) warm air conditioner, freezing and (follows Ring) according to the difference of its compress mode, reciprocating, swinging, scroll-type, spiral, centrifugal, axial-flow type etc. can be divided into.

At present detachable Rotary Compressor is the portable compressor that a kind of use screw locking replaces welding, will can be pushed up Lid, bottom, shell, filtering flask are sealed using screw locking, by pumping and motor using screwed lock in enclosure interior.This kind of compression Machine can be removed and installed repeatedly, when compressor exploitation Qualify Phase needs to change pumping and motor repeatedly, when can save a large amount of Between and workload.

As shown in figure 1, the housing of existing detachable Rotary Compressor can be divided into successively from top to bottom roof section 1, motor Section 2, pumping section 3 and bottom section 4, are wherein provided with three bearings 5 in pumping section 3, a screw hole is respectively provided with each bearing 5 6.Compressor is placed on pumping on pumping section bearing 5 when assembling, and the bottom surface of pumping cylinder 31 contacts with bearing 5, pumping positioning Hole overlaps with the screw hole 6 on bearing 5, and pumping is fixed on bearing 5 by screw.After pumping locking, in cylinder 31 The air entry in portion overlaps with the suction hole 7 in pumping section 3, now between pumping section bearing 5 and pumping section suction hole 7 it is vertical away from It is corresponding with the 1/2 of the height H of pumping cylinder 31 from D.

Same Frame machines, different according to pumping capacity, cylinder has various height.Therefore assembling difference cylinder is high During the detachable Rotary Compressor of degree, because difference cylinder height will be needed using not corresponding to the height of different pumping section bearings Same pumping section, it is therefore desirable to which the model of pumping section is more.Since so, different not only can increase produces into the model of pumping section This, also makes operation sequence become complicated.If in addition, in proof procedure certain height cylinder authentication failed, its corresponding pump Pu section is also ineffective, causes to waste.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of detachable swinging compression Machine.

For achieving the above object, this utility model adopts following technical proposals：

A kind of detachable Rotary Compressor, including housing, the motor in housing, pumping and the gas in pumping Cylinder and gasket ring；The housing is included successively from top to bottom for roof section, motor segment, pumping section and bottom section；The pumping section On be provided with several bearings, a screw hole is respectively provided with described each bearing；The correspondence pump is provided with the gasket ring The installing hole of the screw hole on the section bearing of Pu；The pumping is located on pumping section bearing, and the gasket ring is arranged in the pumping Cylinder bottom surface and bearing between；The screw hole three on installing hole and bearing on location hole, gasket ring in the pumping Overlap, the pumping, gasket ring are fixed by screw and bearing；Suction hole weight on the air entry and pumping section of the cylinder middle section Close；The gasket ring thickness deducts the 1/2 of cylinder height for the vertical dimension between pumping section bearing and pumping section suction hole.

Preferably, the breakthrough mouth that the leaf position of the correspondence pumping disconnects is provided with the gasket ring.

Preferably, internal diameter of the external diameter of the gasket ring less than pumping section.

Preferably, the internal diameter of the gasket ring becomes because of the inwall of gasket ring between bearing edge to bearing screw hole Change and change.

Preferably, the gasket ring is stainless steel.

The beneficial effects of the utility model are by increasing gasket ring on pumping section bearing, and to make gasket ring thickness d be pumping Vertical dimension D between section bearing and pumping section suction hole deducts the 1/2 of cylinder height H, when in assembling difference cylinder height During detachable Rotary Compressor, the pad of respective thickness is increased on pumping section bearing according to difference cylinder requirement for height correspondence Ring, so cause certain pumping section can with general, so since production cost reduce naturally, operation sequence also becomes simple；Separately Outward, if in proof procedure certain height cylinder authentication failed, its corresponding pumping section can also reapply other certain it is high In the cylinder of degree, it is to avoid cause to waste.
