Fig. 2 is the flow chart of experimental rig application method of the present utility model.
Embodiment
In order to more fully understand technology contents of the present utility model, with reference to specific embodiment to skill of the present utility model
Art scheme is described further and illustrated.
The structural representation of the utility model embodiment experimental rig is as shown in Figure 1.
The high temperature and pressure test device of the present embodiment includes pressure source 10, isolation cylinder 20 and capstan 50.Pressure source 10
For pressurized cylinder.Capstan 50 connects workpiece to be tested.It is provided with separator piston 21 in isolation cylinder 20, separator piston 21 is by isolation cylinder
20 are separated into independent two parts 22,23, and a part 23 connects pressure source, the connection capstan 50 of another part 22.Isolation cylinder
In 20 liquid gallium medium is filled with the part 22 of connection capstan 50 and capstan 50.When pressure source 10 is to isolation
The separator piston 21 of cylinder 20 applies pressure, and separator piston 21 promotes liquid gallium medium to pass through the pressure transmission of capstan 50 to work to be tested
On part 70.
Isolation cylinder 20 is externally provided with isolation cylinder heating and thermal insulation set 30, and isolation cylinder 20 can be heated to more than the melting temperature of gallium.
Capstan 50 is externally provided with pipe tracing set 31, and capstan 50 can be heated to more than the melting temperature of gallium.It is to be tested
Workpiece 70 is placed in test specimen heating and thermal insulation part 60, and workpiece 70 to be tested is heated into test temperature (up to thousand degree).Isolation cylinder
Heating and thermal insulation set 30, pipe tracing set 31 are used to ensure that gallium medium is not less than the fusing point of gallium medium, that is, ensure gallium medium
Liquid fluidity.
In addition, high temperature and pressure test device also includes being used to be filled with liquid gallium medium into capstan 50 and isolation cylinder 20
Filling-valve 40.Filling-valve 40 is located on capstan 50 and connected with capstan 50.The external liquid gallium medium of filling-valve 40
Storage device, when filling-valve 40 is opened, liquid gallium medium from filling-valve 40 enter capstan 50 after enter isolation cylinder
The part 22 of 20 connection capstans 50, with to be used.After liquid gallium medium is sufficient much of that, it is necessary to close filling-valve 40 it
After could Opening pressure source 10 work.
The application method flow chart of the high temperature and pressure test device of the present embodiment is as shown in Fig. 2 application method is including following
Step：
Step S1, isolation cylinder 20, capstan 50 and workpiece to be tested 70 be preheating to predetermined temperature；
Step S2, by gallium medium carry out be preheating to temperature more than 30 DEG C, make its keep molten state；
Step S3, the part for connecting capstan 50 to isolation cylinder 20 are filled with the gallium medium of liquid；
Step S4, Opening pressure source 10 are pressurizeed to the separator piston 21 of isolation cylinder 20, promote liquid gallium medium to be tested
The pressurization of workpiece 70 is until off-test；
Step S5, by the gallium dielectric film filter of liquid.
In step sl by opening isolation cylinder heating and thermal insulation set 30, pipe tracing set 31 and test specimen heating and thermal insulation part
60 so that isolation cylinder 20 and capstan 50 are reached between 30 degree~50 degree of predetermined temperature, and workpiece 70 to be tested is heated into examination
Temperature is tested, that is, ensures that gallium medium ensure that liquid, keep mobility after entering, it is to avoid test failure, and temperature model
Enclosing can not cause to scald.
Step S2 is carried out in outside gallium media storage devices, it is therefore an objective to by gallium melting media and holding preferably stream
Dynamic property, otherwise gallium medium once solidification, it is impossible to entered from filling-valve 40 in capstan 50.Preheating temperature needs to exceed gallium Jie
The fusing point of matter, but waste the energy without too high.Step S1 and step S2 can be carried out successively, can also simultaneously be carried out, also may be used
To be first step S2 and then carry out step S1, but final purpose is to allow gallium medium to keep mobility, it is to avoid produce blocking.
In step s3, allow separator piston 21 in the centre position of isolation cylinder 20, open filling-valve 40, open outside gallium and be situated between
Liquid gallium medium is filled into capstan 50 from filling-valve 40 and connects capstan 50 full of isolation cylinder 20 by matter storage device
Part, the part 22 that isolation cylinder 20 at least is connected into capstan 50 is full of, it is to avoid separator piston 21 is reached close to pressurization
Gallium medium is but not reaching at workpiece 70 to be tested during the range of pipeline 50, i.e., can not transmit pressure, and experiment can not be carried out.
In step s 4, start pressure source 10 and promote separator piston 21, separator piston 21 promotes liquid gallium medium to reach and treated
At test piece 70, workpiece 70 to be tested starts to be pressurized, and experiment formally starts.Workpiece 70 is stressed essentially from pressure source 10
Hydraulic coupling, when need to workpiece 70 apply change pressure when, the direct output pressure of control pressure source 10.Test period
It can freely determine, can also test to workpiece 70 and damage.The parameters of workpiece 70 can be by passing in process of the test
Sensor is detected in real time to be come and records in real time, in order to follow-up analysis and research.
In step s 5, first the workpiece 70 after experiment is cooled to and is not less than 30 DEG C, the gallium medium of workpiece 70 is poured out back
Receive, the gallium medium in pressure pipeline 50 and isolation cylinder 20 is replaced out with compressed air to be reclaimed.It is put into after gallium dielectric film filter
Into outside gallium media storage devices to treat that next time uses.
In other embodiments, if test specimen is metal, it can be applied on the parts surface that test specimen is contacted with liquid-gallium medium
Upper protective coating, it is to avoid gallium medium rapidly diffuses into the lattice of some metals and generates alloy with many metals in high temperature.
It is set forth above that technology contents of the present utility model are only further illustrated with embodiment, in order to which reader is easier reason
Solve, but do not represent embodiment of the present utility model and be only limitted to this, any technology done according to the utility model extends or created again
Make, by protection of the present utility model.
