Embodiment
Embodiment 1
The multi-functional pressure testing of automatic control of the present utility model station is that water tank, pump, pipeline and control system are installed on the vehicle frame.After water tank 1 topped up with water, if the pressure testing container is 0＜PN＜1.0Mpa, then adopt on the waterflood pump 2 water and suppress, the export pipeline that is about to water tank 1 connects waterflood pump 2, the outlet of waterflood pump 2 is connected with pressure testing container 5 pipelines through stop valve 3, outlet valve 4 successively, pressure testing container 5 is connected with pressure unit 6, and pressure unit 6 is connected with adjustment control 7 circuit; Be provided with solenoid valve 14 and surplus valve 16 at pressure testing container 5 one ends.Adjustment control 7 is connected with stop valve 3, outlet valve 4 and solenoid valve 14 circuit.On the panel of adjustment control 7, establish alarm 18, tensimeter 19 and touch display screen 20.
The multi-functional pressure testing of automatic control of the present utility model station is that water tank, pump, pipeline and control system are installed on the vehicle frame.After water tank 1 topped up with water,, then adopt water on the waterflood pump 2, supercharge pump 11 to suppress if the pressure testing container is 1.0Mpa≤PN≤16Mpa.The export pipeline one tunnel that is about to water tank 1 connects valve 8 and is connected with pressure testing container 10 pipelines with stop valve 9 through waterflood pump 2, stop valve 3, high-low pressure successively; Another road is connected with pressure testing container 10 pipelines through supercharge pump 11, stop valve 12, outlet valve 13 successively; Pressure testing container 10 is connected with pressure unit 6, and pressure unit 6 is connected with adjustment control 7 circuit; Be provided with solenoid valve 15 and surplus valve 17 at pressure testing container 10 1 ends.Adjustment control 7 is connected valve 8, stop valve 9, stop valve 12, outlet valve 13 and solenoid valve 15 and is connected with circuit with high-low pressure.On the panel of adjustment control 7, establish alarm 18, tensimeter 19 and touch display screen 20.
Pressure testing equipment is being carried out before pressure test begins, is at first setting the termination pressure of pressure testing equipment, as parameters such as pressurize value or dwell times, this be provided with can be on touch-screen direct control; Behind the electric motor starting, waterflood pump obtains starting working behind the power, water filling exhaust in pressure testing equipment.After water completely reaches deflation time in the pressure testing equipment, close the water supply valve door.Pressure testing this moment equipment internal pressure rises gradually, its force value must change by pressure unit image data model and pass to PLC digital display adjustment control, adjustment control carries out digitized processing and setting value comparison, and its pressure value P LC shows and notes simultaneously.When pressure testing equipment internal pressure value during near setting value, the control motor reduces rotating speed, the speed that the equipment internal pressure that slows down rises, stop the motor rotation when reaching pressure threshold, valve-off enters pressure maintenance phase, after reaching the dwell time, then open Draw off valve, the pressure testing process stops.Continue to suppress to equipment as needs, set termination pressure once more, can repeat said process again, then motor start-up treats that the rising of equipment internal pressure reaches the pressure threshold of new settings.In addition, in the pressure build-up test process, whether the control system Auto-Sensing leaks to measured workpiece, if the equipment under test pressure-bearing is leaked, system can close test pump automatically, quits work; Equipment under test does not leak, and the equipment internal pressure is when reaching the upper pressure limit value of setting, and pressure testing also can stop automatically; Suppressing in the process also can be by the pressure test pressure in control system and the pressure unit monitoring equipment, if force value during near atmospheric pressure, can be reported to the police by alarm buzzer.
