Description
Technical field
The utility model relates to Compressor Technology fields, more particularly to a kind of oil return line of compressor.
Background technique
Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to high pressure gas, is the heart of refrigeration system
Dirty, it operates band piston by motor and compresses to it, to exhaust from the refrigerant gas of air intake duct sucking low-temp low-pressure
The refrigerant gas of high temperature and pressure is discharged in pipe, provides power for refrigeration cycle.Wherein screw compressor has that structure is simple, volume
The features such as small, light weight, noise are low, mechanical efficiency is high and smooth running, is widely applied to every field.
When scroll compressor works at present, some mechanical parts inside scroll compressor are easy to take away its internal lubrication
Oil, if make-up oil not in time, will result in each component starved lubrication deficiency in shell causes parts depreciation to aggravate, however general
The cover assembly and high-low pressure chamber demarcation plate of logical low-pressure bubble compressor are formed by high pressure gas chamber and are usually not provided with oil return dress
It sets, leading to remain in the lubricating oil in discharge chamber cannot be recycled, and cause the waste of lubricating oil.
Utility model content
In order to overcome the shortcomings of the prior art, the utility model, which provides one kind, can recycle lubricating oil to portion
The oil return apparatus that part is lubricated.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of oil return apparatus of compressor, including
Shell, described intracorporal one end of shell are equipped with suction chamber, and the intracorporal other end of shell is equipped with discharge chamber, the suction chamber and exhaust
It is equipped with the crankshaft cavity for placing crankshaft between chamber, further includes oil return apparatus, the oil return apparatus includes oil storage tank and oil return line, institute
It states oil storage tank the lower section of discharge chamber is arranged in and is connected to discharge chamber, the lower end of the oil storage tank and one end of oil return line connect
Logical, the other end of the oil return line is connected to crankshaft cavity.
Through the above scheme, out of the air entry of shell sucking ambient atmos to suction chamber, by crank rotation to low pressure
Gas carries out compression and becomes the cold gas processed of high temperature and pressure staying in discharge chamber, then the exhaust outlet being connected to through shell with discharge chamber is arranged
Out, since the cold gas processed in discharge chamber is high pressure, the lubricating oil in oil storage tank is under the action of high pressure cold gas processed, lubricating oil
It is flowed into crankshaft cavity through oil return line and crankshaft is lubricated, the lubricating oil after lubrication drops under discharge chamber through crankshaft rotation
It in the oil storage tank of side, so repeats, to achieve the effect that lubricating oil reuses, avoids the waste of lubricating oil, effectively
Crankshaft component is lubricated, the abrasion of each component in shell is prevented.
Preferably, the bottom surface of the oil storage tank is equipped with recessed portion, the arrival end of the recessed portion and oil return line
Connection.
Through the above scheme, the bottom surface setting recessed portion of oil storage tank can be assembled when dropping onto oil storage tank for lubricating oil
Into recessed portion, return line is more readily flowed into convenient for the lubricating oil in oil storage tank.
Preferably, the oil return line is to be obliquely installed close to the part of oil storage tank, and inclined angle is 45 °
~60 °.
Through the above scheme, it is to accelerate lubricating oil in return line that return line front section, which is arranged to inclination,
Flowing velocity facilitates lubricating oil to flow into lubricating component in crankshaft cavity.
Preferably, the arrival end of the oil return line is gradually expanded to outlet end.
Through the above scheme, it is to allow lubricating oil to act in high pressure that the arrival end of oil return line is gradually expanded to outlet end
Under flowed in crankshaft cavity more quickly each component be lubricated, improve the efficiency of lubrication.
It preferably, further include filter, the filter is arranged on return line.
It through the above scheme, is the profit flowed back into oil storage tank in order to prevent in the arrival end setting filter of oil return line
Lubricating oil can have impurity, flow into the blocking that will cause pipeline in oil return line.
Compared with prior art, the utility model has the beneficial effects that: oil return is arranged between discharge chamber and crankshaft cavity
Pipeline, by the pressure in discharge chamber by lubricating oil be pressed into oil return line in, then through return line flow into crankshaft cavity to component into
Row lubricates, and the oil liquid after lubrication flow back into recycling in oil storage tank, reduces the waste of lubricating oil, can be in time in shell
Component be lubricated, effectively avoid the abrasion between component, improve the service life of compressor.
