Abstract
The utility model relates to an abrasionproof loses centrifugal pump pump cover belongs to mechanical fluid field. The utility model discloses an abrasionproof loses centrifugal pump pump cover, it is the toper structure that the inner chamber of this pump cover seals the mating part with the machine to be equipped with the cowling panel of inside extension on pump cover toper inner chamber, the pump cover is installed at pump body front end, the preceding terminal surface of pump cover and the quick -witted outer loop sealing connection who seals. After the export of impeller threw away the medium, partial medium flow back in the pump cover cavity, because the cavity of pump cover be the toper structure, itself had the effect of diffusion, can reduce the vortex and to the abrasion ability of pump cover cavity, in addition have the cowling panel in the toper cavity, was using the cowling panel can't form the vortex in as the whole annular channel in cross -section, and the medium that the messenger flow back can't wash away pump cover formation, has protected the pump cover not receive the abrasion. The utility model discloses a centrifugal pump pump cover can prevent that the medium of backward flow is rotatory at the seal chamber of pump cover, and the protection pump cover does not receive the abrasion, reduces to leak the potential safety hazard that causes.
Description
Technical field
The utility model relates to a kind of Wear-proof centrifugal pump cover, belongs to mechanical fluid field.
Background technique
Current centrifugal pump cover, as shown in Figure 1, pump cover 1 uses as the back shroud of the pump housing, with machine seal 2 be connected after form the cavity of a seal, make not to be leaked out from the medium of impeller 3 outlet return, but due to the drive of the rotating ring High Rotation Speed in machine envelope 2, medium in its seal chamber defines vortex, if containing solid particle in the medium of conveying, in vortex, the solid particle of High Rotation Speed produces abrasion to pump cover inner chamber, the whole cavity of progressive failure pump cover, causes leakage hidden danger.
Model utility content
The purpose of this utility model is that the cooperating structure sealed to solve conventional centrifugal pump pump cover and machine can make medium form vortex, produces abrasion, cause leakage hidden danger, thus provide a kind of Wear-proof centrifugal pump cover pump cover inner chamber.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Wear-proof centrifugal pump cover of the present utility model, it is cone structure that the inner chamber of this pump cover and machine seal mating part, and on pump cover conical internal cavity, be provided with the current plate extended internally; Pump cover is arranged on pump housing front end, and the outer ring seal that front-end face and the machine of pump cover seal is connected.
After the outlet of impeller throws away medium; certain media is back in pump cover cavity; cavity due to pump cover is cone structure; itself is with the effect of diffusion; the abrasive capacity of wraps correction pump cover cavity can be reduced, to add in cone-shaped cavity with current plate, vortex cannot be formed in the whole ring runner taking current plate as cross section; the medium of backflow cannot be formed pump cover wash away, protect pump cover and do not denuded.
Beneficial effect
Centrifugal pump cover of the present utility model can the medium of anti-backflow rotate at the seal chamber of pump cover, and protection pump cover is not denuded, and reduces the potential safety hazard of leaking and causing.
Accompanying drawing explanation
Fig. 1 is conventional centrifugal pump pump cover structure;
Fig. 2 is the utility model centrifugal pump cover structure;
Wherein 4-pump cover, 2-machine envelope, 3-impeller, 4-current plate.
Embodiment
Connection with figures and embodiment are described further content of the present utility model below.
Embodiment
A kind of Wear-proof centrifugal pump cover of the present utility model, as shown in Figure 2, it is cone structure that the inner chamber of this pump cover 1 and machine seal 2 mating parts, and on pump cover conical internal cavity, be provided with the current plate 4 extended internally; Pump cover 1 is arranged on pump housing front end, and the outer ring seal that front-end face and the machine of pump cover 1 seal 2 is connected.
After the outlet of impeller 3 throws away medium; certain media is back in pump cover cavity; cavity due to pump cover 1 is cone structure; itself is with the effect of diffusion; the abrasive capacity of wraps correction pump cover cavity can be reduced, to add in cone-shaped cavity with current plate, vortex cannot be formed in the whole ring runner taking current plate as cross section; the medium of backflow cannot be formed pump cover wash away, protect pump cover and do not denuded.
Claims (1)
