Description

A kind of Rotary Compressor

Technical field

The utility model belongs to Compressor Technology field, and in particular to a kind of Rotary Compressor.

Background technology

Compressor is a kind of machinery by gas compression lift gas pressure, by the generator of such as motor, turbine etc To its supply electric power, and the working fluid of such as air, cold-producing medium etc is compressed makees work, to improve working fluid pressure Mechanism, this compressor extensively makes in the various applications of the household electrical appliance from such as air-conditioner, refrigerator or the like to factory With according to the difference of its compress mode, reciprocating, swinging, scroll-type, spiral, centrifugal, axial-flow type etc. can be divided into.

Fig. 1 is the structure sectional view of existing Rotary Compressor；Fig. 2 is air-conditioning system refrigerant circulation direction schematic diagram.Such as Shown in Fig. 1-2, existing Rotary Compressor, including housing 2, be arranged on the top cover 1 at the top of housing 2, be arranged on the bottom of housing 2 Bottom 8 and be supported in the foot rest 6 of the bottom of bottom 8；Wherein revolution is collectively formed by top cover 1, housing 2 and bottom 8 and foot rest 6 The shell and bracing frame of formula compressor；Shell is internally provided with motor stator 3, motor rotor 4 and pumping 5；Wherein motor turns Son 4 is located in motor stator 3, and on power transmission shaft of the hot jacket of motor rotor 4 in pumping 5.

The basic functional principle of Rotary Compressor is：During Rotary Compressor energization work, motor stator 3 produces magnetic , motor rotor 4 is rotated, and then drive the drive axis in pumping 5, cam during drive axis on its end Axle can also be rotated and then cause the ring in pumping 5 in the cylinder to do eccentric motion in the cylinder, so as to by the gas of low-temp low-pressure Body coolant media is compressed into the gas of HTHP and is drained in housing by cylinder-bore Jing silencer cover, and the gas of HTHP is via horse Up to after the gap between the trimming in the outside of stator 3 and motor rotor 4, refrigerant circulation system is entered by the blast pipe 7 being arranged in top cover 1 In system 10.

A certain amount of refrigerator oil 9 can be marked with bottom 8 in above-mentioned Rotary Compressor operation process, if but note The refrigerator oil 9 for entering is very few, then can increase the abrasion probability of pumping 5, reduces the service life of Rotary Compressor；If injection Refrigerator oil 9 is excessive, then can cause the waste of resource and affect monomer efficiency.When Rotary Compressor is carried out at a high speed in air-conditioning During operating, the refrigerator oil inside Rotary Compressor can raise refrigerant machine oil liquid level with running up for pumping 5, and When refrigerant is circulated in systems, refrigerator oil can be attached in liquid refrigerants, and then can be attached to Rotary Compressor housing 2 On inwall, when refrigerator oil flows downward along the inwall of housing 2, the upper bracket bevel edge 511 in pumping 5 can store part Refrigerator oil, the herein setting of upper bracket bevel edge 511 is mainly conducive to the peace of pumping 5 when Rotary Compressor is assembled Dress, but this process can then cause the refrigerator oil at Rotary Compressor bottom pumping 5 to reduce, and then increase the mill of pumping 5 Damage situation, reduces its service life.
