Description of drawings
Fig. 1 is the structured flowchart of an embodiment of the utility model pressure resistant vessel pressure experimental device.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is carried out detailed description.
Please refer to Fig. 1, this is shown in Figure 1 to be the structured flowchart of an embodiment of the utility model pressure resistant vessel pressure experimental device.It is example that this embodiment carries out pressure test with water heater liner as pressure resistant vessel, three water heater liners simultaneously, and its structure and process of the test are following:
Water pump 5 as shown in Figure 1, that the test unit of this embodiment includes water tank 4, is connected with water tank 4.Water pump 5 also is connected with 3 tunnel multiplexing pipelines 83 respectively through inlet pipeline 81; And the end that multiplexing pipeline 83 is connected with inlet pipeline 81 also is connected with water tank 4 through discharge pipe line 82; The other end of multiplexing pipeline 83 is connected with a water heater liner to be tested respectively, is respectively water heater liner 11, water heater liner 21 and water heater liner 31.On every multiplexing pipeline 83, be respectively arranged with a solenoid valve, corresponding inner bag to be tested, be respectively with the corresponding solenoid valve of water heater liner 11 12, with water heater liner 21 corresponding solenoid valves 22 and with water heater liner 31 corresponding solenoid valves 32.These three solenoid valves can be realized the conducting of different directions under the control of controller 7, make current on corresponding multiplexing pipeline 83, to flow towards different directions.Specifically, be example with one of them test branch road, if supercharging, promptly need water filling in the water heater liner 11, then solenoid valve 12 conducting directions will make current from inlet pipeline 81 along multiplexing pipeline 83 entering water heater liners 11; If water heater liner 11 pressure releases, when being draining, the conducting direction of control electromagnetic valve 12 is realized the round-robin of current for making current from water heater liner 11, flow out, flow in the water tank 4 through multiplexing pipeline 83 and discharge pipe line 82, improves the current utilization factor.And for speed is suppressed in raising, each solenoid valve preferably adopts high-speed electromagnetic valve, in conjunction with the control of main control unit 71, makes its spool work in continuous variation but not on off state, to realize the continuous adjusting of current.
The foregoing description uses multiplexing pipeline and solenoid valve to realize supercharging and pressure release, can the short form test apparatus structure, reduce the taking of controller control port, and reduce cost.But, be not limited to this structure, also can independent inlet pipeline, entering water electromagnetic valve and discharge pipe line and drain solenoid valve be set to each inner bag to be tested.This separate structures ratio is easier to understand and realize, does not do concrete elaboration at this.
Inlet pipeline 81 is provided with pressure transducer, is used to gather the pressure signal on the inlet pipeline 81, and then the pressure signal of the water heater liner that obtains to test.
In addition; Test unit also includes controller 7; Miscellaneous part is connected and the following content of control procedure reference in frequency converter 72, input block 73 and the display unit 74 that this controller 7 specifically includes main control unit 71 and is connected with main control unit, controller and test unit.
Wherein, the signal output part of frequency converter 72 is connected with water pump 5, under the control of main control unit 71, water pump 5 is carried out VFC.Specifically; The pressure signal input end of main control unit 71 is connected with pressure transducer 6; Gather the pressure signal of inlet pipeline 81, and according to this pressure signal control of conversion device and then the rotating speed speed through Frequency Converter Control water pump 5, thereby the size of control hydraulic pressure.
The switching signal output terminal of main control unit 71 is connected with solenoid valve 12, solenoid valve 22 and solenoid valve 32 respectively, with the on off state of control electromagnetic valve, realizes water inlet, draining control to the water heater liner that it connected.
Input block 73 can and the preferred keyboard that adopts realize that the user can set parameters such as the maximum pressure, minimum pressure, operating rate, work number of times, dwell time, pressure release time of test.
When test unit is worked, with water tank 4 and three water heater liners to be tested fills with water all; Then, through the keyboard to set up test parameters, begin test.In the process of the test, detect the test pressure value, after force value reaches setting value, close each solenoid valve, carry out pressurize through pressure transducer 6; After the dwell time reaches, control each solenoid valve and open, carry out pressure leak process, the water after the pressure release is back in the water tank 4, recycles with realization.
The top pressure that this test unit is suppressed is 2.0MPa, and the dwell time can be set arbitrarily between second at 0.1-10, and stand-by time can be set between second at 0.1-6, and test number (TN) can be set and suppress 100,000 times.Suppress frequency and can reach the soonest 45 times/minute, satisfy the GB requirement, and suppress setting value and be depressured to 15% of setting value then, working in reciprocating mode, pressurize worked in 10 minutes again after 10,000 times.Be fixed on through frequency of operation under the pressure of a setting, can realize quick supercharging or step-down through the duty that changes solenoid valve then, improved the speed of suppressing greatly frequency converter 72.
Above embodiment only in order to the technical scheme of explanation the utility model, but not limits it; Although the utility model has been carried out detailed explanation with reference to previous embodiment, for the person of ordinary skill of the art, still can make amendment to the technical scheme that previous embodiment is put down in writing, perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of relevant art scheme break away from the spirit and the scope of the utility model technical scheme required for protection.
