Existing applicant has carried out Change In Design to hermetically-sealed construction, " people " word O-ring seal sealing of adopting, this structure is without overtesting, sealing property can't be understood, now require under the still unprocessed prerequisite of hub body, blade, the pressure test device at design one cover is can simulated impeller inside and outside when the working condition of pressure is all arranged this sealing position according to the performance parameter that obtains after the test, carries out design optimization to seal member again.
Summary of the invention
Technical matters to be solved by this invention provides a kind of before hub body, impeller are still undressed, just can carry out the pressure testing device for adjustable impeller sealing component of inside, external pressure environment simulation test to seal member.
In order to solve the problems of the technologies described above, the pressure testing device for adjustable impeller sealing component that the present invention adopts, comprise " people " font O-ring seal, the pressure testing parent that axle hole bit architecture that cooperates with impeller by hub body and size are made is provided with hollow cavity and upper port and lower port, in the hollow cavity of described pressure testing parent, be provided with the intermediate isolating lid of turn arbitrarily, in described intermediate isolating lid forms the hollow cavity of described pressure testing parent to simulate, the last pressure testing chamber of external pressure environment and following pressure testing chamber, leave the gap between described intermediate isolating lid bottom and the described pressure testing parent, and be formed with seal groove between the sidewall of the sidewall of described pressure testing parent and described intermediate isolating lid, in described seal groove, be provided with gasket ring, be provided with spring between described gasket ring and the described pressure testing parent, pressure ring is fitted in described " people " font O-ring seal sealing in the described seal groove and described pressure ring is fastening is installed on the described pressure testing parent, removable seal is equipped with stifle on the upper port of described pressure testing parent, the described stifle of going up is provided with water injection hole, removable seal is equipped with down stifle on the lower port of described pressure testing parent, and described stifle down is provided with down water injection hole.
Be provided with a silk hole in the middle of the described intermediate isolating lid.
Described " people " font O-ring seal is " people " font rubber seal.
Adopt the pressure testing device for adjustable impeller sealing component of technique scheme, at first, press axle hole bit architecture and size that hub body cooperates with impeller, make the pressure testing parent, seal member structure when using according to on-the-spot reality, the spring of in the pressure testing parent, packing into, gasket ring, " people " shape O-ring seal and gland.When the simulated interior pressure environment, cover lower port with following stifle, water filling is pressurized to the operating mode actual internal pressure, carries out the inside water pressure test.When the simulation external pressure environment, to use stifle and cover upper port, water filling is pressurized to the actual external pressure of operating mode, carries out the external water pressure pressure testing.
Pressure testing device of the present invention has been compared following characteristics with conventional art:
1, can simulate seal member at the scene under the actual motion pressure environment, seal member is tested;
2, traditional pressure test process need be with large-scale hub body and impeller assembling back pressure testing, and volume is big, and regulating with assembling all needs by driving, labour intensity greatly, very inconvenient.Adopt this apparatus structure simple and convenient, volume is less, easily regulates, and need not by driving, and labour intensity is little.
3, can be at hub body, blade is undressed just can seal be tested before good, reaches the purpose that shifts to an earlier date optimal design, has saved the entire product R﹠D costs.
In sum, the present invention is a kind of before hub body, impeller are still undressed, just can carry out inside, external pressure environment simulation test and pressure testing device for adjustable impeller sealing component simple in structure, easily manufactured, dependable performance to seal member.
Description of drawings
Fig. 1 is a pressure testing device structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing pressure testing device of the present invention is further described.
Referring to Fig. 1, the pressure testing parent 2 that axle hole bit architecture that cooperates with impeller by hub body and size are made is provided with hollow cavity 14 and upper port 13 and lower port 10, in the hollow cavity 14 of pressure testing parent 2, be provided with the intermediate isolating lid 5 of turn arbitrarily, be provided with a silk hole 17 in the middle of the intermediate isolating lid 5, in intermediate isolating lid 5 forms the hollow cavity 14 of pressure testing parent 2 to simulate, the last pressure testing chamber 15 and the following pressure testing chamber 11 of external pressure environment, intermediate isolating is covered between 5 bottoms and the pressure testing parent 2 and is left gap 18, and be formed with seal groove 12 between the sidewall of the sidewall of pressure testing parent 2 and intermediate isolating lid 5, in seal groove 12, be provided with gasket ring 7, be provided with spring 6 between gasket ring 7 and the pressure testing parent 2, pressure ring 3 is fitted in the seal groove 12 4 sealings of " people " font rubber seal and pressure ring 3 fastening being installed on the pressure testing parent 2, removable seal is equipped with stifle 1 on the upper port 13 of pressure testing parent 2, last stifle 1 is provided with water injection hole 16, removable seal is equipped with down stifle 8 on the lower port 10 of pressure testing parent 2, and following stifle 8 is provided with down water injection hole 9.
