Abstract
A fully-enclosed oil-dropping casing for refrigerating compressor is provided, which is an improvement over prior compressor casing, in particular a concave groove is designed at bottom of the lower casing. The improvement allows the installation of the whole compressor pump body to be downward moved, so as to reduce oil level depth while ensuring that the crankshaft is immersed in oil level, hence oil charge can be reduced, and the concave groove can promote turbulent flow, reduce vortex, improve oil-pumping efficiency, is applicable for improving casings of various refrigerating compressors.
Description
(1) technical field: the utility model relates to the improvement technology of refrigeration compressor, is a kind of Totally Closed Refrigerating Compressor Oil-reducing Housing.
(2) background technique: hermetically sealed compressor is in the abundant cooling of running for heating component such as the sufficient lubrication that guarantees each kinematic pair and motors, required refrigerator oil is absolutely necessary, and refrigeration compressor refrigerator oil injection amount is mainly determined by following several respects: (1) satisfies the sufficient lubrication of each kinematic pair of compressor and frictional heating and the required oil mass of abundant cooling that the motor feels hot; (2) satisfy the circulation oil mass of bringing refrigeration system pipeline and associated components into by refrigeration agent.So will reduce oil filling amount can only retain the oil mass consideration from reducing, and can only reduce the distance of bent axle lower end surface to lower shell body internal support pin attachment face and will reduce the retention oil mass.But in order to guarantee compressor unlikely bump lower shell body in bent axle lower end in the running start-up course, the bent axle lower end surface will guarantee certain distance to the lower shell body foot, and actual design is 13-14mm.Like this, both are conflicting again.
(3) summary of the invention: the purpose of this utility model is to solve above-mentioned contradiction, reduces and retains oil mass, and a kind of Totally Closed Refrigerating Compressor Oil-reducing Housing is provided.
Concrete scheme of the present utility model is: offer a groove in the bottom of compressor lower shell body.
Described groove is φ 10-90mm, and the circular pit groove of dark 3-8mm also can be the groove of different shape such as oval, square, polygonal.
The disalignment 0-40mm of the center line of described groove and housing bottom.
The utility model fuel-economizing principle analysis is as follows:
Totally-enclosed reciprocating-piston type refrigerating compressor is that the compressor pump body portion is fused by spring cupport structure and housing parts, forms by the housing welded seal at last.The lower casing inside of compressor is filled with a certain amount of refrigerator oil, during compressor operating, refrigerator oil is up by the oil-sucking hole suction of bent axle lower end, a part of oilhole ejection by the eccentric shaft end face forms the ring-type mist of oil and sprays the whole motor and the pump housing, the motor and the pump housing are cooled off, simultaneously each kinematic pair is lubricated, is back to lower casing then; A part is brought each pipeline of refrigeration system into for cooled dose, flows back to compressor by sucking pipe then; Another part resides in housing.
Compressor is in the cooling cycle system working procedure, guarantee normal pump oil, the bent axle lower end pasta certain depth that must submerge will guarantee that simultaneously compressor does not clash into lower shell body in the bent axle lower end surface in transportation and start-up course, and bent axle lower end to lower housing portion will guarantee certain distance.
Under the prerequisite that guarantees the oil mass that refrigeration system is required, under the situation of injecting identical oil mass, existing housing bent axle the submerge depth as shallow 3-8mm of pasta of depth ratio the utility model housing of pasta that submerges, that is to say, the oil mass that the oil mass that existing housing body is retained is retained than the utility model housing is howed 3-8mm nearly, and being converted to refrigerator oil is 30-80ml.Therefore, adopt the utility model housing can save refrigerator oil 30-80ml, reach about the 10-25% of the total injection of S series oil mass.
The utility model is simple in structure, reduces oil filling amount, reduces the complete machine cost, and groove can promote turbulent flow, reduces vortex, improves pump oil efficient.
(4) description of drawings:
Accompanying drawing is application mounting structure figure of the present utility model.
Among the figure: 1-upper shell, 2-compressor pump assembly, 3-lower shell body, 4-bent axle, 5-groove.
(5) embodiment:
Referring to accompanying drawing, the utility model tool upper shell 1 and following 3, particularly be suppressed with a groove 5 in the bottom of lower shell body 3, this groove is φ 40, the circular pit groove of dark 8mm (also can be according to different big or small compressors at φ 10-90mm, value between the dark 3-8mm), the groove center line in the utility model and the center of housing bottom can be offset setting between 0-40mm.After housing in the utility model improved, wherein compressor pump assembly 2 and bent axle 4 can move down 8mm, thereby it is dark to make oil filling amount reduce 8mm.
Claims (3)
1. a Totally Closed Refrigerating Compressor Oil-reducing Housing includes upper shell and lower shell body, it is characterized in that: in the lower shell body bottom design groove is arranged.
2. a kind of Totally Closed Refrigerating Compressor Oil-reducing Housing according to claim 1 is characterized in that: described groove is φ 10-90mm, and the circular pit groove of dark 3-8mm also can be oval, square, polygonal groove.
3. a kind of Totally Closed Refrigerating Compressor Oil-reducing Housing according to claim 1 is characterized in that: the disalignment 0-40mm of the center line of described groove and housing bottom.
