Abstract
The utility model discloses an oil applying mechanism applied to a compressor, the compressor comprises a shell and a crankcase which is internally arranged in the shell, a crankshaft of the crankcase is provided with an oil applying passage and an exhaust passage, the lower end surface of the crankshaft is lower than the oil level, the upper passage and the exhaust passage are communicated with the crankcase, and the outlet of the oil applying passage is positioned above the outlet of the exhaust passage; the oil applying stability is facilitated, each kinematic pair of the compressor is fully lubricated, and the purposes of improving the efficiency and the reliability of the compressor are achieved.
Description
Technical field
The utility model relates to compressor field, in particular to a kind of oil-adding mechanism applied to compressor.
Background technique
Small enclosed reciprocating compressor be it is a kind of in refrigerator, refrigerator system for being set to what refrigerant was compressed
It is standby.Oil circuit design is an important link in compressor design, not only directly related with the performance of compressor, or even can be determined
The reliability of compressor.Good lubrication forms boundary friction in the form of oil film, to improve the performance and reliability of compressor.
Current common small-sized totally-enclosed formula reciprocating compressor, wherein fuel sucking pipe is mounted on crankshaft lower end, and fuel sucking pipe oils
Mouth is located at oil level hereinafter, when compressor is run, and refrigeration oil is compressor oil-supplying by fuel sucking pipe: fuel sucking pipe upper hydraulic fluid port easily exists
Disturbance is generated under oil level, is unfavorable for the stability to oil.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of oil-adding mechanisms applied to compressor, eliminate biography
Fuel sucking pipe in structure of uniting, to solve the above-mentioned many defects caused by the prior art.
A kind of to achieve the above objectives, the present invention provides the following technical solutions: oiling machine applied to compressor
Structure, the compressor include shell and are built in the intracorporal crankcase of shell, and the crankshaft of the crankcase is equipped with oil channel and exhaust
The lower end surface in channel, crankshaft is lower than oil level, above has channel and exhaust passage to communicate with crankcase, the outlet in the channel that oils is located at
The top of Vent passageway.
Preferably, the lower end surface inner hole processing of the crankshaft is conical.
Preferably, the import in the exhaust passage and the channel that oils is lower than the top end face of bellmouth.
Preferably, with crankshaft center axis at angle, exhaust passage is parallel with crankshaft center axis in the channel that oils.
Preferably, the outlet of the exhaust passage is connected by return gas channel with the channel that oils.
Preferably, the top of the crankshaft is equipped with upper exhaust passage, is connected to outside crankcase by exhaust pipe.
It is using the beneficial effect of above technical scheme: is designed by the utility model, on the one hand reduce zero, compressor
On the other hand part reduces the disturbance at the access opening that oils to oil liquid, is conducive to the stability to oil, obtains each kinematic pair of compressor
To sufficient lubrication, achieve the purpose that promote compressor efficiency and reliability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of crankshaft.
Wherein, oil channel, 53- return-air of 1- shell, 2- crankcase, 3- exhaust pipe, 5- crankshaft, 51- bellmouth, 52- is logical
Road, 54- exhaust passage, 6- oil level.
Specific embodiment
The preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 and Fig. 2 show specific embodiment of the present utility model: a kind of oil-adding mechanism applied to compressor, the pressure
Contracting machine includes shell 1 and the crankcase 2 that is built in shell 1, and the crankshaft 5 of the crankcase 2 is equipped with oil channel 52 and exhaust
The lower end surface in channel 54, crankshaft 5 is lower than oil level 6, above has channel 52 and exhaust passage 54 to communicate with crankcase 2, oil channel
52 outlet is located at the top that exhaust passage 54 exports.
It is processed into bellmouth 51 in the lower end surface of crankshaft 5；The import in exhaust passage 54 and the channel 52 that oils is lower than bellmouth 51
Top end face；Channel 52 and 5 central axis of crankshaft oil into angle, exhaust passage 54 is parallel with 5 central axis of crankshaft；Exhaust passage 54
Outlet be connected with the channel 52 that oils by return gas channel 53；The top of crankshaft 5 is equipped with upper exhaust passage 3, passes through exhaust pipe 3
It is connected to outside crankcase 2.
It is designed by the utility model, on the one hand reduces Parts of Compressor, on the other hand reduced at the access opening that oils pair
The disturbance of oil liquid is conducive to the stability to oil, so that each kinematic pair of compressor is obtained sufficient lubrication, reaches promotion compressor efficiency
And the purpose of reliability.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
