Measure exceeded, the method for direct compressor unit energization air-discharging can be used to check the oil dripping amount of exhaust outlet of compressor, but the method
Test is due to contain oxygen and water vapour in air, and compressor can cause oil high-temperature oxydation at compressor valve group in idle running,
Phenomena such as valve group carbon deposit, compressor is damaged, and due to high temperature, compressor, which is discharged in gas, has spray pattern mist of oil, Wu Fajin
Row is collected, and in this approach there is also inaccuracy, the method can not accurately and effectively judge compressor oil drainage amount, while also can for institute
Damage compressor.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of measurement compressor oil drainage amount device, can fast and effectively sentence
Whether disconnected compressor oil drainage amount is exceeded, avoids the exceeded compressor of oil drain quantity from being assembled on refrigerator, to solve to cause in the prior art
Above-mentioned multinomial defect.
To achieve the above object, the present invention provides following technical scheme：One kind measurement compressor oil drainage amount device, including
Protective gas and oil-liquid separator, protective gas are arranged on the suction end of compressor, and oil-liquid separator is arranged on compressor
Exhaust end, the oil pocket of oil-liquid separator is provided with observation panel, scale value is identified with the transparent material of observation panel.
Preferably, throttling is provided between the protective gas and compressor and between oil-liquid separator and compressor
Valve.
Preferably, pressure gauge is provided between the compressor both sides and choke valve.
Preferably, the device also includes aerofoil fan, and aerofoil fan is arranged on compressor opening position.
A kind of method for measuring compressor oil drainage amount, comprises the following steps,
1) compressor is accessed into measurement compressor oil drainage amount device, using drying nitrogen or other types protectiveness gas
Body, by choke valve, pressure gauge, access compressor air suction end；Compressor air-discharging end be sequentially connected gas-liquid separator, pressure gauge,
Choke valve；
2) after running compressor, exhaust side oil is gentle together to discharge, and after gs-oil separator, oil can be stayed in into oil
In gas separating device, pass through liquid visor and corresponding scale, it can be determined that the oil drain quantity of unit interval inner compressor.
Preferably, the operating condition of system is adjusted by adjusting the choke valve of suction and discharge side, simulation actual compressor is practical
System.
Preferably, if compressor is a point cold compressor, aerofoil fan is opened.
Beneficial effect using above technical scheme is：The device of the present invention can fast and effectively judge the row of compressor
Oil mass, and compressor can be protected, it can be continuing with after compressor test, simultaneity factor can be arranged to different operating modes
Type.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein, 1-- protective gas, 2-- choke valves, 3-- pressure gauges, 4-- compressors, 5-- oil-liquid separators, 6-- axles
Flow fan.
Embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 shows the embodiment of the present invention：One kind measurement compressor oil drainage amount device, including protective gas 1
With oil-liquid separator 5, protective gas 1 is arranged on the suction end of compressor 4, and oil-liquid separator 5 is arranged on the exhaust of compressor 4
End, the oil pocket of oil-liquid separator 5 are provided with observation panel, scale value are identified with the transparent material of observation panel.
Choke valve 2 is provided between protective gas 1 and compressor 4 and between oil-liquid separator 5 and compressor 4, is compressed
Pressure gauge 3 is provided between the both sides of machine 4 and choke valve 2；The device also includes aerofoil fan 6, and aerofoil fan 6 is arranged on compressor 4
Opening position.
A kind of method for measuring compressor oil drainage amount, comprises the following steps,
1) compressor is accessed into measurement compressor oil drainage amount device, using drying nitrogen or other types protectiveness gas
Body, by choke valve, pressure gauge, access compressor air suction end；Compressor air-discharging end be sequentially connected gas-liquid separator, pressure gauge,
Choke valve；
2) after running compressor, exhaust side oil is gentle together to discharge, and after gs-oil separator, oil can be stayed in into oil
In gas separating device, pass through liquid visor and corresponding scale, it can be determined that the oil drain quantity of unit interval inner compressor.
Choke valve by adjusting suction and discharge side adjusts the operating condition of system, simulates actual compressor utility system；Such as
Fruit compressor is a point cold compressor, opens aerofoil fan.
Using drying nitrogen or other types protective gas, by choke valve, pressure gauge, compressor air suction is accessed
