Description
Technical field
Compression set technical field is the utility model is related to, in particular to a kind of fueller and screw compressor.
Background technology
Screw compressor because its efficiency high, small volume, light weight, operate steadily the features such as be widely used in refrigeration air-conditioner
With the field such as heat pump.In general, screw compressor is by closed shell, fixed scroll, orbiter, support, bent axle, anti-rotation
Mechanism fueller and motor are formed, and the molded line of dynamic and static scroll plate is spiral shape, and orbiter is with respect to fixed scroll bias simultaneously
180 ° of installations of difference, then form multiple crescent-shaped spaces between dynamic and static scroll plate.In orbiter with fixed scroll
The heart is pivot and when making the revolution translation without rotation with certain radius of turn, and outer ring crescent-shaped space will be constantly in
The heart is moved, and now, refrigerant is gradually pushed to central space, and its volume constantly reduces and pressure constantly raises, until and central row
Stomata communicates, and high pressure refrigerant is discharged the pump housing, completes compression process.
The patent of patent document 201110173522.8 discloses a kind of fueller structure of screw compressor, using this
Structure can solve the problems, such as compressor oil-supplying, and making is simple, cost is low.In the prior art scheme, complete machine is filled by fuel feeding
Put to each friction pair, rolling pair feed lubrication, after lubricating oil dispersed, form oil gas with the high-temperature high-pressure refrigerant gas of flowing and mix
Compound, and be discharged outside compressor so that oil mass is reduced inside compressor, and compressor may be in oil starvation state.
As shown in figure 1, air-conditioning compressor is switched to cooling condition operation in heating, such as defrost is heated in winter
When, it can be connected by the compression exhaust of four-way reversing valve 1 ' high-pressure side 4 ' with the low-pressure side of evaporator 2 ', such compressor 3 ' is internal to be moistened
Lubricating oil is largely carried in the presence of pressure difference, while oil return needs certain time, and under the situation of oil starvation, oil pump occurs short
The situation of time fuel feeding deficiency, compressor 3 ' obtain insufficient lubrication, reduce reliability.
In addition, after horizontal compressor is shut down, the lubricating oil in fueller can return to compressor oil storage under gravity
In pond, start next time needs first to empty the refrigerant ability continuous oil supply in fueller, and compressor has during refrigerant is emptied
Being likely to occur oil starvation causes inordinate wear.If compressor frequently move by stop and start, the probability that the phenomenon occurs is bigger, and then influences pressure
Contracting machine reliability.
