Background technology
Currently, a connecting tube can be arranged in most of compressor between press exhaust outlet and press bottom oil sump, this
Guan being exactly press oil exit pipe, main function is to prevent compressor oil sump oil mass excessively high.The use principle of this press oil exit pipe
Siphonage is mainly utilized, so-called siphonage is exactly the pressure near high-velocity fluid can be lower than normal pressure.Press
Oil exit pipe position is lower than oil level highest warning line, to realize oil level always in Safe Levels section.
When the compressor is operating, the high-speed gas flow velocity of exhaust outlet of compressor is higher, at this time the pressure near exhaust pipe compared with
Low, the pressure of oil sump is compared to higher, and connecting tube is under oil sump and exhaust outlet differential pressure action, higher than compressor oil drainage pipe position
Oil is discharged to exhaust outlet of compressor.
However, when compressor operating frequency is high, the oil drain quantity of exhaust outlet of compressor is huge, compresses motor spindle oil level meeting
Rapid decrease, if can not ensure effective fuel feeding at this time, compressor can be because can not enough lubricate to burn, this is for complete machine system
System is blast phase destruction.

Description of the drawings
The attached drawing constituted part of this application is used to provide further understanding of the present invention, schematic reality of the invention
Example and its explanation are applied for explaining the present invention, is not constituted improper limitations of the present invention.In the accompanying drawings：
Fig. 1 is the overall structure diagram of the embodiment of compressor according to the present invention.
Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer, right with reference to embodiment and attached drawing
The present invention is described in further details.Here, the exemplary embodiment and its explanation of the present invention be for explaining the present invention, but simultaneously
It is not as a limitation of the invention.
Fig. 1 shows the embodiment of the compressor of the present invention, which includes main casing 10, oil sump 20, exhaust outlet, row
Oil pipe 30 and flow regulator 40.Wherein, oil sump 20 is formed in main casing 10, and exhaust outlet is arranged on main casing 10, oil extraction
Pipe 30 is connected to oil sump 20 and exhaust outlet, and flow regulator 40 is arranged on oil exit pipe 30.
It applies the technical scheme of the present invention, the flow of oil exit pipe 30 is adjusted by flow regulator 40.When the fortune of compressor
When line frequency is low, the flow of oil exit pipe 30 is tuned up by flow regulator 40, accordingly even when the air pressure of exhaust outlet of compressor and oil
The pressure difference in pond 20 is smaller, and oil exit pipe 30 can also obtain enough oil supply exhaust outlets from oil sump 20；When the operation frequency of compressor
When rate is high, the flow of oil exit pipe 30 is turned down by flow regulator 40, accordingly even when the air pressure of exhaust outlet of compressor and oil sump 20
Pressure difference it is larger, excessive oil will not be allowed to supply exhaust outlet by oil exit pipe 30, avoid the oil level in oil sump 20 from declining too fast
Caused fuel feeding not in time, ensure that the performance of compressor, prevent compressor from being burnt because of oil starvation.
Optionally, as shown in Figure 1, oil sump 20 is formed in the bottom of main casing 10.
As shown in Figure 1, in the technical solution of the present embodiment, compressor further includes operation component 50 and controller, operation
Component 50 is arranged in main casing 10, and controller is electrically connected with flow regulator 40.When in use, it is obtained and is run by controller
The running frequency of component 50, later controller controlled in inverse ratio according to running frequency flow regulator 40 adjusting flow, i.e.,
The flow that oil exit pipe 30 is tuned up when running frequency is low turns the flow of oil exit pipe 30 down when running frequency is high.
As a preferred embodiment, as shown in Figure 1, compressor further includes liquid level viewer 60, liquid level viewer
60 be arranged on main casing 10 at oil sump 20 correspondingly position.When in use, oil sump 20 is observed by liquid level viewer 60
The liquid level of inner fluid, fluid is replenished in time when the liquid level of 20 inner fluid of oil sump is too low.More preferably, in liquid level viewer
Scale is identified on 60, scale is corresponding with the liquid level in oil sump 20.By scale, user more can easily learn oil
Liquid level in pond 20, with it is contemplated that suitable time addition fluid.As shown in Figure 1, liquid level includes highest warning liquid level 70, oil extraction
The interface that pipe 30 is connected with oil sump 20 is less than highest warning liquid level 70, to realize oil level always in Safe Levels section.
In the above-described embodiment, flow regulator 40 is adjustable opening size device, i.e., the present invention is by adjusting oil extraction
The mode of the aperture of pipe 30 adjusts the flow of oil exit pipe 30.

Adjust device, can to avoid air conditioner in high-frequency in compressor fuel feeding not in time caused by machine system damage the problem of.
The present invention also provides a kind of control method of compressor, the control method of the compressor includes：
Obtain the running frequency of compressor；
The flow of the oil exit pipe 30 between the oil sump 20 and its exhaust outlet of compressor, flow and fortune are controlled according to running frequency
Line frequency is inversely proportional.That is, the raising of the running frequency with compressor, and turn the flow of oil exit pipe 30 down；With compressor
The reduction of running frequency, and tune up the flow of oil exit pipe 30.
Control method using the present invention tunes up the flow of oil exit pipe 30 when the running frequency of compressor is low, so i.e.
Keep air pressure and the pressure difference of oil sump 20 of exhaust outlet of compressor smaller, oil exit pipe 30 can also obtain enough oil supplies from oil sump 20
Exhaust outlet；When the running frequency of compressor is high, turn the flow of oil exit pipe 30 down, accordingly even when the air pressure of exhaust outlet of compressor with
The pressure difference of oil sump 20 is larger, and excessive oil will not be allowed to supply exhaust outlet by oil exit pipe 30, avoided under the oil level in oil sump 20
The too fast caused fuel feeding of drop not in time, ensure that the performance of compressor, prevent compressor from being burnt because of oil starvation.
In above-mentioned control method, the aperture mode by controlling oil exit pipe 30 controls the flow of oil exit pipe 30, convenient fast
It is prompt.
