Gauge can accurately measure the flow of Roots vaccum pump, but the model of Roots vaccum pump is different, the Roots to various models
When vacuum pump is exhausted, needs the prime donkey pump coordinating different capacity to coordinate, make existing test equipment not possess
Versatility, needs the difference of the rate of air sucked in required according to Roots vaccum pump, and the expense preparing cooperating equipment is the highest.
Utility model content
This utility model purpose is to provide a kind of Roots vacuum Pump Characteristic Test System, and the Roots being adapted to various rate of air sucked in required is true
Empty pump, strong adaptability, testing cost is low.
Roots vacuum Pump Characteristic Test System described in the utility model, including test cover and Roots vaccum pump, Roots vacuum pumping
Gas end is connected to test cover, and the exhaust end of Roots vaccum pump is connected respectively to return valve and vacuum breaker one end, and backflow is adjusted
The joint valve other end is connected to test cover by effusion meter, and the vacuum breaker other end is connected to holding vacuum pump.
Existing air inlet system and exhaust system are tested system, are become blood circulation by described Roots vacuum Pump Characteristic Test System, it is to avoid
Use prime donkey pump to be discharged by the supercharging air of Roots vacuum pumped, and be the use of return valve and replaced,
By regulation return valve aperture, make the air inlet air pressure of return valve less than giving vent to anger air pressure, it is achieved that air pressure promotes, and will
The air discharged is transmitted back to test cover by effusion meter again, thus achieves circulation, and tests sieve of various rate of air sucked in required
Thatch vacuum pump, it is thus only necessary to the aperture of regulation return valve, it is not necessary to change according to the rate of air sucked in required difference of Roots vaccum pump
Prime donkey pump, and the price of a return valve is far below a prime donkey pump, and need not according to Roots vaccum pump
Change, both improve versatility, and reduced testing cost.
Described Roots vacuum Pump Characteristic Test System, the pipeline between exhaust end and the return valve of Roots vaccum pump is provided with
Surge tank A, surge tank A are provided with row's mouth pressure regulation valve and row's mouth vacuometer.Surge tank A is used for measuring Roots vacuum and pumps into
The stable force value of mouth, bleed pressure regulator can suitably open to improve the pressure at expulsion of Roots vaccum pump, as needed to reduce
Pressure at expulsion, then open holding vacuum pump and suitably open regulation valve, and row's mouth vacuometer is used for measuring pressure at expulsion.
Described Roots vacuum Pump Characteristic Test System, the pipeline between the exhaust end vacuum pump of Roots vaccum pump is provided with heat exchanger.
Can effectively in Roots vaccum pump extract out air lower the temperature, make this utility model can long-play, or because of temperature become
Change, cause testing inaccurate.
This utility model compared with prior art has the beneficial effect that
Described Roots vacuum Pump Characteristic Test System, tests the Roots vaccum pump of various rate of air sucked in required, it is thus only necessary to regulation backflow is adjusted
The aperture of joint valve, it is not necessary to change prime donkey pump according to the rate of air sucked in required difference of Roots vaccum pump, and a backflow regulates
The price of valve is far below a prime donkey pump, and need not change according to Roots vaccum pump, had both improve versatility, and had had reduction
Testing cost.

Detailed description of the invention
Below in conjunction with this utility model, Roots vacuum Pump Characteristic Test System is described further:
Embodiment 1: as it is shown in figure 1, Roots vacuum Pump Characteristic Test System described in the utility model, including test cover 3 He
Roots vaccum pump 4, test cover 3 is provided with inlet vacuum meter 2 and inlet pressure regulation valve 1, and Roots vaccum pump 4 is bled to hold and connected
To test cover 3, the exhaust end of Roots vaccum pump 4 is connected respectively to return valve 11 and vacuum breaker 10 one end, backflow
Regulation valve 11 other end is connected to test cover 3 by effusion meter 13, and vacuum breaker 10 other end is connected to holding vacuum pump 9.
Embodiment 2: on the architecture basics described in embodiment 1, between exhaust end and the return valve 11 of Roots vaccum pump 4
Pipeline be provided with surge tank A7, surge tank A7 and be provided with row's mouth pressure regulation valve 6 and row's mouth vacuometer 8.
Embodiment 3: on the architecture basics described in embodiment 2, on the pipeline between the exhaust end vacuum pump of Roots vaccum pump 4
Being provided with heat exchanger 5, coolant outlet and the entrance of heat exchanger 5 are connected to cooling water source.
Embodiment 4: on the architecture basics described in embodiment 3, is provided with surge tank between return valve 11 and effusion meter 13
B12, surge tank B12 are provided with backflow vacuometer 14 and reflux pressure force regulating valve 15.
Concrete testing procedure is:
(1) use holding vacuum pump 9 that the air in space in all systems is carried out evacuation；
(2) use holding vacuum pump 9 and row's mouth pressure regulation valve 6 for controlling the pressure at expulsion of Roots vaccum pump 4；
(3) after the pressure of Roots vaccum pump 4 is maintained and to require pressure rating by holding vacuum pump 9, by closing vacuum conditions
Holding vacuum pump 9 is cut out system by valve 10.
And use effusion meter 13 to test air inflow at the air inlet of test cover 3 (4)；
