Abstract
Disclosed is an oil effluence decreasing device for a compressor. The compressor comprises a sealing casing, a motor component, a pump component, an oil tank and an exhaust pipe, wherein the motor component and the pump component are sealed in the sealing casing, the oil tank is arranged on the inner lower portion of the sealing casing, and the exhaust pipe is arranged on the sealing casing. The oil effluence decreasing device is an exhaust baffle plate arranged on the inner side of the exhaust pipe. When the compressor is operated, exhaust with a large quantity of refrigerating machine oil particles flows in the radial direction along the exhaust baffle plate. When the flow direction is changed, heavy fluids (oil drops) flow to an annular oil groove along the baffle plate due to the effect of inertia force, and light fluids bypass the baffle plate and flow to the exhaust pipe of the compressor so that the two-phase fluids are separated and further the number of the oil drops carried by the exhaust of the compressor is greatly decreased. The edge of the exhaust baffle plate is downwardly turned to form the annular oil groove, and the refrigerating machine oil particles in the exhaust are separated by the aid of the inertia force effect generated in change of exhaust flow directions. The oil effluence decreasing device is simple and reasonable in structure, capable of greatly decreasing circulatory oil effluence and high in running reliability.
Description
Technical field
The utility model relates to a kind of rotary compressor, and particularly a kind of compressor is told the oil mass absorber.
Background technique
The high pressure gas of compressor is discharged from the pump housing, flows through vent and stator rotor gap on the rotor then, wherein can carry a large amount of refrigerator oil particles in the exhaust.The exhaust of band oil droplet can directly rush at upper shell of compressor after by rotor in the present compressor arrangement, flows out from outlet pipe at last.Refrigerator oil is run out of compressor with refrigerant like this, accumulates in heat exchanger surface, influences heat exchange efficiency; Same, therefore the situation of oil starvation also can appear in compressor, influences the reliability of compressor operating.
The model utility content
The purpose of this utility model aim to provide a kind of simple and reasonable, can reduce compressor effectively and tell oil mass, improve the compressor of the reliability of compressor operating and tell the oil mass absorber, to overcome deficiency of the prior art.
A kind of compressor by this purpose design is told the oil mass absorber, described compressor comprises seal casinghousing, be encapsulated in electric machine assembly and pump assembly in the seal casinghousing, be arranged on bottom in the seal casinghousing oil sump, be arranged on the outlet pipe on the seal casinghousing, its structure characteristic is that the described oil mass absorber of telling is the exhaust screen that is arranged on the inboard place of outlet pipe.
Described electric machine assembly, pump assembly and oil sump are arranged in the seal casinghousing from top to bottom successively, and outlet pipe is arranged on the seal casinghousing top; Exhaust screen is arranged in the cavity between electric machine assembly and the outlet pipe.
The downward flange in the edge of described exhaust screen, flange forms an annular oil groove; The curved hook solid of flange, straight tabular or quarter bend is hook-shaped.When the curved hook solid of flange and quarter bend were hook-shaped, the refrigerator oil particle of separating in the exhaust can be assembled in oil groove; When flange is straight when tabular, the refrigerator oil particle of separating in the exhaust forms larger oil droplet and drips, and drips to stator line bag place.
The core of described exhaust screen convexes to form conical surface, remains with certain interval with the balancing rotor interblock, forms a structure that plays guide functions between exhaust screen and electric machine rotor, flows to oil groove in order to guiding gas, improves Oil-gas Separation efficient.
Described electric machine assembly comprises motor lines bag, stator component, rotor part and is arranged on the balancing rotor piece at rotor part top; Rotor part is connected with the pump housing by bent axle, and the bent axle lower end extends in the oil sump.Axial vent is arranged in its rotor, have the gap between rotor part and the rotor.High pressure gas is discharged from the pump housing, flows through vent and stator and rotor gap on the rotor then.
The flange of described exhaust screen is provided with more than one oil dripping aperture, makes the refrigerator oil of separating from exhaust form larger oil droplet and drips, and drips to stator line bag place.
The annular oil groove of described exhaust screen is communicated with the oil sump of compressor bottom by the following oil-piping of vertically placing, and the refrigerator oil of separating from exhaust can be back in the oil sump of compressor bottom.
Described exhaust screen is fixedlyed connected with enclosing housing by barrier support or fixing bolt.
The exhaust meeting of carrying a large amount of refrigerator oil particles during compressor operating of the present utility model is along exhaust screen toward the radial direction diffluence, when changing the flow direction, because The Effect of Inertia Force, heavy fluid (oil droplet) flows in the annular oil groove along baffle plate, lighter fluid is then walked around baffle plate and is flowed to compressor exhaust pipe, thereby two-phase fluid is separated, significantly reduce the entrained oil droplet quantity of compressor air-discharging.The downward flange in exhaust screen edge forms an annular oil groove, the inertial force effect that utilizes exhaust air flow to turn to, the refrigerator oil particle in the separation off gas.It is simple and reasonable, can reduce the characteristics that oil mass is told in circulation significantly, and the element that is increased is nonrotational part, the operational reliability height.
