Specific embodiment
Below in conjunction with specific embodiment, the present invention is further elaborated.
Injection drainage type oil filling device as shown in Figs. 1-3, the lubricating oil being connected including upper port with fuel tank 8
Channel 3, pressure sensor 6 and control valve 7 are disposed on the tube body of grease channel 3, and control valve 7 is solenoid valve；
In another embodiment of the present invention, pressure sensor 6 is external in suction chamber 4.The lower port of grease channel 3 is communicated with suction
It enters the room 4, the Working medium gas channel 1 of nozzle 2 of the one end with contraction-like port is provided in suction chamber 4, wherein nozzle 2 is shunk
The converging angles of shape port are 13 °, and in the present embodiment, Working medium gas flow is situation minimum in actual condition, in engineering
In practice, the Working medium gas flow in working medium pipeline is bigger, and the converging angles of required nozzle ports are bigger, of the invention
In another embodiment, Working medium gas flow is situation maximum in actual condition, and the converging angles of the contraction-like port of nozzle 2 are
70°.The exit of nozzle 2 is correspondingly arranged on connect with suction chamber 4 and outlet and mixes with by the oil gas that is connected of lubricating utensil 9
Channel 5 is closed, the cross-sectional shape of suction chamber 4 is circle, and in other embodiments of the invention, which is rectangular or six
Side shape.
The method for carrying out injection drainage type oil filling using above-mentioned apparatus is as follows:
One, gas enters Working medium gas channel 1 from system pipeline, and the air in suction chamber 4 is inhaled in Working medium gas channel 1
Enter, forms certain vacuum degree；
Two, when working medium flow changes, refrigerant flow rate changes therewith, and the pressure in 2 exit of nozzle changes, i.e.,
Change in suction chamber 4 and grease channel 3 with the pressure difference in 2 exit of nozzle；
Three, pressure sensor 6 collects the signal of pressure difference；
Four, the signal collected according to pressure sensor 6 adjusts oiling by PLC come the opening size of adjusting control valve 7
Amount: when working medium flow increases, increase the aperture of control valve 7, increase the adding amount of lubricating oil；When working medium flow reduces, subtract
The aperture of small control valve 7, reduces the adding amount of lubricating oil；
Five, lubricating oil flows through suction chamber 4, obtains in air-fuel mixture channel 5 sufficiently with the gas in Working medium gas channel 1
Mixing completes lubrication subsequently by lubricating utensil 9.
Working principle of the present invention is as follows:
Firstly, Working medium gas enters Working medium gas channel 1 from system pipeline, it is in relatively high pressure lower-speed state；Work as work
Matter is flowed out from Working medium gas channel 1, and when into nozzle 2, since caliber strongly reduces, refrigerant flow rate is sharply increased.
Because the diameter in the Working medium gas channel 1 of the device, grease channel 3 and air-fuel mixture channel 5 is all smaller, respectively
The gravitional force of inner fluid passage can be ignored, and therefore, inner fluid passage can be considered contour flowing.According to Bernoulli Jacob side
Journey,P is the pressure of certain point in fluid in formula, and v is fluid in the flow velocity of the point, and ρ is fluid density, and g is
Acceleration of gravity, h are height where the point, and C is a constant, it may be assumed that kinetic energy+gravitional force+pressure potential=constant.Due to logical
Fluid visibility is contour flowing in road, i.e. h=0, in 2 exit of nozzle, the flow velocity v of fluid be increased dramatically, the pressure p of the position
It strongly reduces, Working medium gas is in low-voltage high speed state, i.e. the pressure in 2 exit of nozzle changes, suction chamber 4 and nozzle 2
Exit produces very big pressure difference, and the air in suction chamber 4 is sucked, certain vacuum degree is formed, thus by being connected with
Lubricating oil is drawn onto the sluice way that 4 shell of suction chamber surrounds by the grease channel 3 of fuel tank 8, and lubricating oil and Working medium gas are together
Into in air-fuel mixture channel 5, and it is sufficiently mixed.
At the same time, when working medium flow changes, refrigerant flow rate can change therewith, the lubricants capacity for needing to fill
It can change therewith, suction chamber 4 caused by the variation of flow velocity and grease channel 3 and the pressure difference in 2 exit of nozzle change, and pressure passes
Sensor 6 is connected with PLC control system, is collected into pressure signal transmission to PLC by pressure sensor 6, is adjusted and controlled using PLC
The aperture of valve 7 carrys out injection flow of the regulating oil tank 8 into the device, to adjust the adding amount of lubricating oil.When working medium flow increases
When, 2 exit Working medium gas flow velocity of nozzle also increases with it, and 2 outlet pressure of nozzle is caused to become lower than before, and pressure passes
Sensor will receive signal, by PLC control unit, increase the aperture of control valve 7, increase the adding amount of lubricating oil, with
Flow with increase；When working medium flow reduces, the lubricants capacity of required filling should also be reduced therewith, and nozzle 2 goes out at this time
Working medium gas flow velocity is also reduced therewith at mouthful, causes 2 outlet pressure of nozzle to become lower than before, pressure sensor 6 will
Signal is received, by PLC control unit, reduces the aperture of control valve 7, reduces the adding amount of lubricating oil, to match reduction
Flow.Enter the Working medium gas flowed out in the lubricating oil and Working medium gas channel 1 of suction chamber 4 by grease channel 3 in oil gas
It is sufficiently mixed in hybrid channel 5, subsequently by lubricating utensil 9, completes lubrication.
What has been described above is only a preferred embodiment of the present invention, but the invention is not limited to above-mentioned specific embodiment parties
Formula without departing from the concept of the premise of the invention, can also be made several for those of ordinary skill in the art
Modification and improvement, these are all within the scope of protection of the present invention.
