Description
Technical field
The utility model relates to a kind of lower equilibrium block for rotor-type compressor.
Background technique
Rotor-type compressor is applicable in refrigeration (heat) circulatory systems such as refrigerator, air conditioner, refrigerating machine, heat pump water heater, for guaranteeing the steadily reliable rotation of compressor drum, as shown in Figure 1, conventionally at the upper and lower part of rotor 1 end face, be respectively equipped with equilibrium block 2 and lower equilibrium block 3, as shown in Figures 2 and 3, the lower equilibrium block 3 of tradition is designed to half nahlock, the border shape right-angle plane 31 in 90 ° of the projecting height of half nahlock and rotor 1 lower end surface 11.In compressor operating, there is certain technological deficiency in this lower equilibrium block 3, as shown in Figure 1, when rotor 1 high speed rotating, the air-flow of 31 pairs, the outstanding plane of this lower equilibrium block 3 after baffler on compressor 4 is discharged produces great disturbance, form windage, cause the power consumption of compressor to increase, and rotating speed is higher, power consumption is larger.The refrigerator oil of taking out of with upper baffler 4 relief openings is broken up by the outstanding plane 31 of lower equilibrium block 3 simultaneously, form the very little mist of oil of diameter, under the effect of gas force, enter compressor housing epicoele, part mist of oil is discharged by relief opening, after entering system, affect heat exchange efficiency, another part mist of oil forms hydrops at compressor housing epicoele, and the oil return of compressor inside is reduced, thereby affects the reliability of compressor operating.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lower equilibrium block for rotor-type compressor, this lower equilibrium block has overcome conventional balanced block structured defect, reduce the windage effect that lower equilibrium block rotation produces, reduce compressor power consumption and oil recycle ratio, improved the heat exchange efficiency of reliability and the air-conditioning system of compressor operating.
For solving the problems of the technologies described above, the utility model comprises for the lower equilibrium block of rotor-type compressor the equilibrium block body of being located at rotor lower end surface, and described equilibrium block body is half nahlock, and two end faces of described half nahlock are inclined-plane or arc shaped surface.
Further, the angle of inclination on two of above-mentioned half nahlock inclined-planes is 25～65 °.
The lower equilibrium block that is used for rotor-type compressor due to the utility model has adopted technique scheme, be that this equilibrium block comprises the equilibrium block body of being located at rotor lower end surface, described equilibrium block body is half nahlock, and two end faces of described half nahlock are inclined-plane or arc shaped surface.This equilibrium block has overcome conventional balanced block structured defect, reduces the windage effect that lower equilibrium block rotation produces, and reduces compressor power consumption and oil recycle ratio, has improved the heat exchange efficiency of reliability and the air-conditioning system of compressor operating.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the schematic diagram that under traditional compressor, equilibrium block is connected with rotor;
Fig. 2 is the structural representation of equilibrium block under traditional compressor;
Fig. 3 is the side view of Fig. 2;
Fig. 4 is that the utility model is for the structural representation of the lower equilibrium block of rotor-type compressor;
Fig. 5 is the side view of Fig. 2.
Embodiment
As shown in Figure 4 and Figure 5, the utility model comprises for the lower equilibrium block of rotor-type compressor the equilibrium block body 3 of being located at rotor lower end surface, and described equilibrium block body 3 is half nahlock, and two end faces 31 of described half nahlock are inclined-plane or arc shaped surface.The material of this equilibrium block body 3 can be the high density materials such as iron, copper or high manganese steel.
Further, the angle of inclination on two of above-mentioned half nahlock inclined-planes 31 is 25～65 °.
This lower equilibrium block becomes inclined-plane or arc shaped surface to form streamlined end face the boundary design of outstanding rotor end face height, take rotor lower end surface as benchmark, equilibrium block body is more than half nahlock or smaller part nahlock, its streamlined end face can reduce the rotor disturbance of equilibrium block protrusion surface to air-flow at present that run up, the cold media air collision that reduces and discharge from the pump housing and the probability that produces tiny oil droplet, reduce compressor power consumption effectively.The refrigerator oil of simultaneously taking out of along with relief opening is also difficult for being clapped broken formation mist of oil, make refrigerator oil under the effect of gravity, get back to the bottom oil sump in compressor with the form of large particle oil droplet, avoid under the effect of air-flow refrigerator oil along with relief opening is discharged, reduce compressor oil circulation rate, be beneficial to the oil return of compressor inside, improve the reliability of compressor operating.
To certain, adopt the compressor of this lower equilibrium block to carry out performance and pasta viewing test, confirm that this lower equilibrium block is for the impact of compressor performance and reliability.
(1) the cold power test of monomer:
Under declared working condition, this lower equilibrium block is compared conventional construction equilibrium block scheme, and cold power difference is little, and enter power, has obvious reduction.During rotor speed 4020rpm, enter when power fall is 1.7%, 5400rpm, to enter power fall and reach 5.1%.Concrete test data is as shown in the table:
(2) air conditioner for matching test:
Under maximum cooling condition 93Hz, compressor power consumption is compared conventional balanced block structure and is reduced 50W left and right, and amplitude reaches 2.2%.
(3) compressor bottom oil sump pasta viewing test, under compressor high speed high load operating mode 7200rpm, by visor under compressor, observe oil sump pasta position, compressor bottom, adopt the above 21mm of pasta positional distance dust collection ring of this lower equilibrium block, and conventional balanced block structure only has 14mm.
