Technical field
The utility model relates to a kind of high temperature and high pressure environment motor rotary seal proving installation.
Background technology
At present, the telescoping ram machine operation is under high temperature and high pressure environment in the electric Image-forming instrument development, and its output shaft needs rotary seal simultaneously, and the quality of rotary seal and life-span directly influence the operate as normal of instrument.For guaranteeing that instrument can operate as normal, need test this rotary seal before use.Proving installation to motor rotary seal test need cover whole motor at present, owing to need distribution to connect, so this apparatus structure is very complicated, and bulky, can only be at big baking oven build-in test, and rate of warming is slow, test period is long, and testing cost is very high, and efficient is very low.
The utility model content
The technical problems to be solved in the utility model provides a kind of high temperature and high pressure environment motor rotary seal proving installation that can test rotary seal and simple in structure and low in cost fast.
In order to address the above problem, the utility model provides a kind of high temperature and high pressure environment motor rotary seal proving installation, comprising:
The pressure testing cylinder, described pressure testing cylinder is a barrel-like structure, the inner fluid of filling;
Cylinder cap, described cylinder cap flexibly connect described pressure testing cylinder, and described cylinder cap is by the hermetically-sealed construction motor output shaft that is connected, and described cylinder cap is provided with the pouring orifice that is communicated with described pressure testing cylinder interior.
Further, described hermetically-sealed construction comprises O type circle and the fixed cover that is equipped with between described cylinder cap and motor output shaft web member, the fixedly connected described cylinder cap of described fixed cover one end, and the other end leans described O type circle.
Further, also be provided with thrust bearing between described cylinder cap and the described motor output shaft web member.
Further, the fixedly connected described electric machine casing of described cylinder cap also is connected with bearing disc between described cylinder cap and the electric machine casing.
Further, also be provided with needle bearing between described cylinder cap and the described motor output shaft web member.
Further, the described cylinder cap described pressure testing cylinder that is threaded.
The utlity model has following advantage:
1, cylinder cap and motor output shaft are connected in the utility model, realize pressure testing inner cylinder sleeve dress output shaft and rotary seal thereof, and in the proving installation of whole motor need not being packed into, need not the distribution cabling, only need to realize that cylinder cap and motor output shaft are connected, simple in structure, and the pressure testing cylinder is less, can realize heating fluid fast, tests, the efficient height, cost is low.
2, the utility model is simple in structure, heating, simple, the convenience of test process, and it is few to relate to link, and the utility model cost of manufacture is cheap, and can carry out standardization and make, and conveniently promotes the use of.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 shows a kind of high temperature and high pressure environment motor of the utility model rotary seal proving installation utilization structure synoptic diagram;
Fig. 2 shows among Fig. 1 A to structural representation;
Fig. 3 shows among Fig. 1 B to enlarged diagram.
Embodiment
As shown in Figure 1-Figure 3, the utility model comprises pressure testing cylinder 1 and cylinder cap 2.Pressure testing cylinder 1 is a main body, can link to each other with heating arrangement to heat; Cylinder cap 2 flexibly connects with pressure testing cylinder 1, connects pressure testing cylinder 1 back and forms airtight cavity 3, motor 4 output shafts 41 is inserted in this airtight cavity 3 test.
In the utility model, hermetically-sealed construction 5 comprises the O type circle 51 and fixed cover 52 that is equipped with between cylinder cap 2 and motor output shaft web member 42, the fixedly connected cylinder cap 2 of fixed cover 52 1 ends, and the other end leans O type circle 51.This O type circle 51 is the agent structure of rotary seal, is the main body of test.By to this O type circle 51 running status and detection in life-span in high temperature and high pressure environment, can learn the reliability that this O type circle 51 is worked in subsurface environment, also just obtained the performance of rotary seal.
In the utility model, also be provided with thrust bearing 6 between cylinder cap 2 and the motor output shaft web member 42.Because fluid is heated to produce and expands in the airtight cavity 3, thereby produces bulging force, promotes cylinder cap 2 and moves to motor 4, makes 2 pairs of motors of cylinder cap 4 produce thrust, so need between motor 4 and cylinder cap 2 thrust bearing 6 be set.According to motor output shaft web member 42 shapes and actual needs two groups of thrust bearings 6 can be set, to cushion this thrust respectively.
In the utility model, cylinder cap 2 fixedly connected motor 4 housings also are connected with bearing disc 7 between cylinder cap 2 and motor 4 housings.This bearing disc 7 can prevent that cylinder cap 2 from directly impacting motor 4 housings under the high-temperature oil liquid thrust, produce infringement to motor 4.
In the utility model, also be provided with needle bearing 8 between cylinder cap 2 and the motor output shaft web member 42.This needle bearing 8 can be realized the relative rotary motion between motor output shaft web member 42 and the cylinder cap 2 easily.
In the utility model, the cylinder cap 2 pressure testing cylinder 1 that is threaded.It is simple, easy to operate to be threaded.Between cylinder cap 2 and pressure testing cylinder 1, also hermetically-sealed construction need be set, as O type circle etc.
The utility model is simple in structure, heating, simple, the convenience of test process, and it is few to relate to link, and the utility model cost of manufacture is cheap, and can carry out standardization and make, and conveniently promotes the use of.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
