4th, circulating pump 5, check valve 6 and electrical ball valve 7, are provided with electrical ball valve 8 on the second pipe, the check valve 6 and electronic
Third pipeline is also associated between ball valve 7, the third pipeline is connected with the outlet of screw pump 9, the pushing part of the screw pump 9
It is connected with servo motor 10.
In present embodiment, the servo motor 10 is connect by gearbox 11 with the pushing part of leading screw pump 9, utilizes speed change
Case can slow down to the output of servo motor, so that pushing course is more steady.It is additionally provided in the first pipe
First pressure sensor 12 and pressure gauge 13, the first pressure sensor 12 and pressure gauge 13 are located at electrical ball valve 7 and test
Between the test mouth of case, pressure condition can be observed by first pressure sensor 12 and pressure gauge 13 at any time, tied convenient for statistics
Fruit.
Electrical ball valve 14 is additionally provided between the circulating pump 5 and check valve 6.Between the circulating pump 5 and electrical ball valve 14
Also it is connected by the 4th pipeline with water tank 1, regulating valve 15 and second pressure sensor 16 is provided on the 4th pipeline.Pass through
Regulating valve, the flow velocity that can be discharged with water tank.
During utility model works, first workpiece for measurement is connected into test box, opens solenoid valve 3, electrical ball valve 7, electronic
Ball valve 8 and electrical ball valve 14 start circulating pump 5 and start to fill, after a period of time can discharge the gas in workpiece for measurement.
Then according to test parameters setting pressure, frequency and number, control servo motor is operated, and servo motor drives screw pump real
It is now pressurized, the speed and cycle-index of servo motor are adjusted to test parameters, until experiment is completed.
It is not difficult to find that the utility model drives screw pump to be pressurized using servo motor, while by controlling servo electric
The rate of machine realizes low-frequency test, so as to ensure that pressure-resistant element will not damage due to frequency is excessively high.
