Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment of the present utility model relates to the static hydrostatic testing machine of a kind of high pressure, as shown in Figure 1, comprise water tank 1, first liquid supercharge pump 2, second liquid supercharge pump 3 and the 3rd liquid booster pump 4, described water tank 1 is connected with first liquid supercharge pump 2, second liquid supercharge pump 3 and the 3rd liquid booster pump 4 successively by pipeline, the endpiece of described the 3rd liquid booster pump 4 is connected with the installation valve piece 5 in chamber, described the 3rd liquid booster pump 4 and the pipeline of installing between valve piece 5 are provided with return pipe 6, on described return pipe 6, unloader 7 are installed; The working pressure range of described first liquid supercharge pump 2, second liquid supercharge pump 3 and the 3rd liquid booster pump 4 raises successively.The backwater end of described return pipe 6 passes into described water tank 1.The control end of described first liquid supercharge pump 2, second liquid supercharge pump 3 and the 3rd liquid booster pump 4 is all connected with driving source of the gas 9 by solenoid valve 8.Between described water tank 1 and first liquid supercharge pump 2, be also provided with filtrator 10.Between described the 3rd liquid booster pump 4 and installation valve piece 5, be provided with pressure transducer 11.The test pressure scope of described first liquid supercharge pump 2 is 0-15MPa; The test pressure scope of described second liquid supercharge pump 3 is 0-90MPa; The test pressure scope of described the 3rd liquid booster pump 4 is 0-200MPa.
As can be seen here, native system is mainly used pressurized air for power source, usings supercharge pump as pressure source, drives bleed pressure to be directly proportional to output hydraulic pressure power.By to driving the adjustment of bleed pressure, can carry out step-less adjustment to output hydraulic pressure power.When atmospheric pressure and fluid pressure balance, Pneumatic liquid supercharge pump stops action automatically, and output pressure is also stabilized on the pressure of setting.By controlling the air inflow of source of the gas, operating frequency that can control pump, thereby the delivery rate of control system.
This system adopts height medium lift pump to be used in conjunction with, and low-lift pump is realized the function of low pressure test (LPT) and the pre-water-filling of system and exhaust, and pressure is between 0-15MPa test pressure; The working pressure range of medium lift pump is between 0-90MPa, and the working pressure range of high-pressure pump, between 0-200MPa, is realized pressure in comprehensive covering of 0-200MPa by cooperation, guarantees controllability and the control accuracy of output pressure.
In order to guarantee the display precision of output pressure, also output pressure grade is divided into Three Estate accordingly, according to the difference of test products, select, between three tunnels, there is interlock function, once there be maloperation, as low pressure instrument test high pressure workpiece, system can also lock by automatic-prompting, to guarantee the security of whole system.In addition, the precision of sensor can adopt 0.5%F.S and 0.25%F.S, to guarantee data acquisition and control and display precision, according to the difference of range, selects, and meets the use needs of different brackets.
When carrying out exhaust, pneumatically powered hydraulic pump sucks water from water tank through filter, and water enters the test piece in test specimen case through the retaining valve of supercharge pump.When pressure arrives certain value, unloader carries out pressure release, repeats several times, and the air in emptying system and test specimen, then closes unloader.
When carrying out pressurized test, low pressure liquid supercharge pump is started working, and water enters test specimen through supercharge pump, and pressure starts to increase; When pressure reaches the maximum output valve of low pressure liquid supercharge pump, by press liquid supercharge pump proceed pressurization; When pressure reaches the maximum output valve of middle press liquid supercharge pump, by highly pressurised liquid supercharge pump, proceed pressurization, until test pressure value.
When carrying out off-load, open unloader and carry out pressure release, now liquid booster pump quits work, and completes once test.After having tested, the automatic fitration of leaking is reclaimed.
