Description
Technical field
This utility model belongs to fluid conveying machine technical field, is specifically related to a kind of centrifugal pump cover water pressure test tightness measuring device, the sealing device of especially independent to accessory pump cover hydraulic pressure test.
Background technology
The sealing of pressure part and bearing capacity detection are critical processes during pump manufactures, and water pressure test detection is not only economy but also convenient detection means.Traditional method be all pump cover and the pump housing are attached together after carry out pressure test, install, dismantle and waste the plenty of time, production efficiency is low.Next to that often there is no the pump housing when sending out pump cover accessory or maintenance, for guaranteeing quality and running safety, it is necessary to individually carry out water pressure test test.
Summary of the invention
The purpose of this utility model there is provided a kind of centrifugal pump cover testing pressure sealing device, and it is reliable, and highly versatile is simple to operate, low cost, solves pump cover accessory and the problem of pump cover maintenance sealing pressure detecting.
Realize described purpose described in the utility model to be adopted the technical scheme that: sealed base is upper end open and surrounding and the cylindrical cavity of bottom lock, the upper end open end face of sealed base places interchangeable flange, pump cover seam end face is placed on again interchangeable flange upper surface, platen edge is pressed in pump cover upper surface and is connected to by studs in the screw that sealed base is corresponding, the small end of pump cover is closed with blank flange and is connected, and sealed base bottom is provided with the pipe screw joint of water receiving press.
Interchangeable flange is the most corresponding with the contact surface position of sealed base be configured with seal groove, interchangeable flange hole with the contact surface position of pump cover seam the most corresponding seal groove that is configured with, seal groove configures O RunddichtringO；Equipped with sealing gasket between small end end face and the blank flange end face of pump cover.
The seal groove of assembling O RunddichtringO than sealing ring standard shallow 0.5～1mm, the interchangeable flange aperture ratio pump cover stop portion big 1mm in aperture.
On sealed base outer wall, the uniform reinforcement that arranges, reinforcement has lifting eye；Equal height cushion block it is also configured with between pressing plate and pump cover.
On pressing plate, the installing hole of the studs of configuration is waist-shaped hole；Sealing gasket between small end end face and the blank flange end face of pump cover is urethane pad.
Work process of the present utility model is: first connect hydraulic press, fills it up with tap water in sealed base reservoir chamber, successively mounting O-shaped sealing ring, interchangeable flange, O RunddichtringO, pump cover assembly, by the uniform compression of pressing plate, carries out sealing stress test.Testing various sizes of pump cover in uniform range, only need to change interchangeable flange can realize.
The beneficial effects of the utility model are: broken the fixed pattern thinking jointly carrying out sealing stress test with the pump housing after attaching together for a long time, solve pump cover accessory and pump cover keeps in repair the problem individually carrying out sealing pressure detecting.Having work efficiency high, it is convenient to change, it is simple to installs, dismantle, highly versatile, it is adaptable to the water pressure test detection of many specifications small lot seriation pump cover.
Accompanying drawing explanation
Enforcement principle of the present utility model and technical scheme are further detailed by the following drawings.
Fig. 1 is overall assembly structure figure of the present utility model.
In figure: 1-equal height cushion block；2-pressing plate；3,6-nut；4,8-plain washer；5,9-studs；7-spring washer；10,11-blank flange；12-urethane pad；13-iron sheet；The interchangeable flange of 14-；15,17-O type seals；16-sealed base；18-pump cover；19-pipe screw joint.
Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model and operating principle are carried out clear, complete description.
As shown in the figure, this utility model is a kind of centrifugal pump cover sealing device for water pressure test, specifically include that sealed base 16, interchangeable flange 14, equal height cushion block 1, pressing plate 2, studs 5,9 and other auxiliary members, pump cover 18, interchangeable flange 14, sealed base 16 by being superimposed together, between load O type and seal 15,17, forms the inner chamber of one closing, by the uniform compression of pressing plate 2, the deflection utilizing O type to seal 15,17 seals, and constantly pressurization is tested, and it is 4MPa that this device can test maximum pressure.Interchangeable flange can be replaced according to pump cover size, and pressing plate waist-shaped hole length is relatively big, can be adjusted according to pump cover size.The structure of sealed base 16 is by steel plate, large diameter steel pipe is welded, in view of load-bearing and intensity, uniform outside large diameter steel pipe weld reinforcement, lifting hole(eyelet) is opened on all reinforcements, do not limited by direction when movement, lifting, bottom large diameter steel pipe, had the pipe screw joint 19 connecting hydraulic press, it is simple to removed the filthy water of intracavity.Each sealing surface has O groove, it is contemplated that the deformation of O and the pressure born, and groove depth is than standard shallow 0.5～1mm.Seal groove on interchangeable flange 14 is for the sealing of pump cover, and cylindrical is slightly less than the inward flange of the studs 5 of pressing plate 2 configuration, selects the steel plate of different-thickness according to the size of flange hole, increases intensity.
The operating principle of this utility model device is: after square joint under hydraulic press rubber hose coupling and the water-bed seat of examination being connected → filled in trying the bottom seat tap water → connected by pump cover small end blank flange, by shown position place → compress periphery → unlatching hydraulic press with pressing plate, and slowly pressurize, observe pressure gauge reading, when reaching requirement (the highest 4MPa), pressurize 30min, No leakage, phenomenon of sweating → closedown hydraulic press → dismantle, clear up, dry up, qualified parts warehouse-in.
This utility model simple in construction, efficiently, easy to maintenance, highly versatile, it is applicable to the water pressure test detection of many specifications small lot seriation pump cover, solves pump cover accessory and pump cover keeps in repair the problem individually carrying out sealing pressure detecting, there is stronger application value.
