Description

A kind of compressor balance piston

Technical field

The utility model relates to a kind of Refrigeration & Air-Conditioning class technical field, especially a kind of compressor balance piston.

Background technique

Compressor in refrigeration equipment is that refrigerant circulation provides the pressure of flowing, and gaseous coolant is adopted after induction chamber sucking It is exported after gaseous coolant is pressurized with circumference of impeller rotary motion, the initial pressure set of gaseous coolant is generally tolerance interval Minimal pressure force value also reduce the operating power consumption of compressor convenient for reducing energy consumption and cost and extend the service life of compression, or The pressurized other refrigerants of impeller are changed by the gaseous coolant initial pressure of original state and have dynamic variation, as impeller is pressurized For a MP, the initial pressure of gaseous coolant is n MP, then pressurized gaseous coolant pressure is n+a MP, then just leading Cause output gaseous coolant pressure be not it is constant, have unstable hidden danger to the refrigeration effect of refrigeration equipment.

Utility model content

The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of compressor balance piston, packet The balance flange left end of main body containing dummy piston, elastic seal ring, dummy piston main body sets circumferential surface as the arc of arc surface Main body sets arcuate socket in dummy piston main body, sets positioning step on the right side of the big end of arcuate socket, balance flange right end set it is outer only Mouthful, male half coupling is arranged elastic seal ring, and the utility model is made of steel spring plate, can effectively be balanced pressurized through impeller Impact force of the gaseous coolant when runner turns upward is balanced by the balance inside elastic micro-motion of flange, and the elasticity of right end is close Auxiliary rest and reset function are played in seal.

A kind of to achieve the above purpose, the technical solution of the present invention is: compressor balance piston includes dummy piston Main body, elastic seal ring, the balance flange left end of the dummy piston main body set circumferential surface as the curved body of arc surface, put down Arcuate socket is set in weighing apparatus piston main body, sets positioning step on the right side of the big end of the arcuate socket, the right end for balancing flange sets male half coupling, institute It states male half coupling and is arranged elastic seal ring.

Further setting, the curved body left end are smaller diameter end.

The smaller diameter end of further setting, the arc surface left end of the curved body and curved body connects, the other end to Right simultaneously upwardly extend simultaneously connect with the excircle of balance flange.

Further setting, it is described balance flange with a thickness of 2mm.

The beneficial effects of the utility model are: the utility model is made of steel spring plate, can effectively balance through impeller Impact force of the pressurized gaseous coolant when runner turns upward is balanced, right end by the balance inside elastic micro-motion of flange Elastic seal ring play auxiliary rest and reset function.

Detailed description of the invention

Fig. 1 is the schematic diagram of the utility model；

Fig. 2 is the scheme of installation of the utility model within the compressor.

In figure: dummy piston main body 1, balance flange 101, curved body 102, arc surface 103, arcuate socket 104, positioning table Rank 105, male half coupling 106, body 2, induction chamber 3, impeller 4, vaneless diffuser 5, elastic seal ring 6, exhaust volute 7.

Specific embodiment

Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.

As shown in Figure 1, a kind of compressor balance piston, includes dummy piston main body 1, elastic seal ring 6, spring steel material 101 left end of balance flange of dummy piston main body 1 set circumferential surface as the curved body 102 of arc surface 103, dummy piston master Arcuate socket 104 is set in body 1, positioning step 105 is set on the right side of the big end of the arcuate socket 104, and the right end of balance flange 101 sets outer stop Mouth 106, the male half coupling 106 is arranged elastic seal ring 6, and the utility model is made of steel spring plate, can effectively balance warp Impact force of the pressurized gaseous coolant of impeller when runner turns upward is balanced by the balance inside elastic micro-motion of flange, The elastic seal ring of right end plays auxiliary rest and reset function.

102 left end of curved body is smaller diameter end.

103 left end of arc surface of the curved body 102 is connect with the smaller diameter end of curved body 102, and the other end is to the right And it upwardly extends connect with the excircle of balance flange 101 simultaneously.

The balance flange 101 with a thickness of 2mm, be conducive to automatic elastic and be displaced, balance gaseous coolant in flow-guiding channel Pressure value.

As shown in Figure 2: after body 2 and the installation of exhaust volute 7, the rotary shaft for the enclosed motor connecting with body 2 extends Outside the interstitial hole of exhaust spiral case 7, the balance flange 101 of dummy piston main body 1 and the elastic seal ring for being sleeved on male half coupling 106 6 seam allowances relative to position being arranged with the inside of exhaust volute 7 embedded simultaneously are connect, and successively load onto vaneless diffuser 5, leaf The rotary shaft fastening of wheel 4 and induction chamber 3, impeller 4 and closed grade is enough, the inner face of impeller 4 and dummy piston main body 1 it is outer The connection of end face collision type, by the pressurized gaseous coolant of impeller 4 when the pressure of flow-guiding channel is greater than the set value, dummy piston master Body 1 can inside elastic displacement, the pressure of gaseous coolant, makes the gaseous coolant pressure of output keep permanent in autobalance flow-guiding channel Deng, elimination have unstable hidden danger to the refrigeration effect of refrigeration equipment.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should all cover within the rights protection scope of the utility model.
