Abstract
The utility model discloses a centrifugal pump with an open impeller. The centrifugal pump comprises a pump body (7), a pump cover, a pump shaft (13), an impeller (9), a mechanical sealing part (16) and a bearing part (19), wherein the pump cover consists of a front pump cover (4) and a rear pump cover (12), a front wear-resisting plate (6) which is connected with the front pump cover and a rear wear-resisting plate (8) which is connected with the rear pump cover are installed between the front pump cover (4) and the rear pump cover (12), and the upper end parts of both the front wear-resisting plate and the rear wear-resisting plate (6 and 8) are installed on the pump body (7). The front pump cover, the front wear-resisting plate, the rear pump cover and the rear wear-resisting plate are installed on the pump body and tightly matched with the pump body, so that the leak problem of a conveyed medium can be avoided, the leakage and pollution can be efficiently prevented, the purity and cleanliness of the conveyed medium can be guaranteed, and the safety performance of the centrifugal pump can be improved.
Description
Technical field
The utility model relates to a kind of centrifugal pump.
Background technique
At present, the centrifugal pump that uses both at home and abroad all adopts unshrouded impeller pattern pump at clear water, oil or the similar products that the medium of carrying contains particle and impurity.The pump cover of this centrifugal pump and wearing plate are the integrated type assembling, the assembling form of the wearing plate of front side exists leak source, the seepage situation can occur, and particularly for oil refining industry, seepage can produce pollution, might catch fire and initiation fire during hot environment, have uncertain potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of leak source, antipollution centrifugal pump with open impellerpump of leakage proof of not existing is provided.
The purpose of this utility model realizes by following technical solution: centrifugal pump with open impellerpump, comprise the pump housing, pump cover, pump shaft, impeller, mechanical seal parts, bearing part, described pump cover is made of front pump cover and rear pump cover, locate to be equipped with the front wearing plate that is connected with front pump cover, the rear wearing plate that is connected with rear pump cover between this front pump cover and rear pump cover, and the upper end portion of forward and backward wearing plate is contained on the pump housing all.
After adopting the utility model structure, because front pump cover all is contained on the pump housing with rear wearing plate and coordinates with the pump housing closely with front wearing plate, rear pump cover, just there is not the problem of fed sheet of a media leak source, thereby effective leakage proof, anti-pollution, purity, the cleaning of fed sheet of a media have been guaranteed, improve the Safety performance of centrifugal pump, eliminated potential safety hazard.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution, the utility model is described further.
Fig. 1 is the structural representation of the utility model centrifugal pump with open impellerpump.
Embodiment
With reference to Fig. 1 as can be known, the utility model centrifugal pump with open impellerpump, comprise the pump housing 7, pump cover, pump shaft 13, impeller 9, mechanical seal parts 16, bearing part 19, described pump cover consists of (for split type) by front pump cover 4 and rear pump cover 12, locate to be equipped with the front wearing plate 6 that is connected with front pump cover, the rear wearing plate 8 that is connected with rear pump cover between this front pump cover 4 and rear pump cover 12, and forward and backward wearing plate 6,8 upper end portion are contained in all on the pump housing 7.
Wherein, front pump cover 4 all is contained on the pump housing 7 by the combination of double-screw bolt 10, nut 11 with rear wearing plate 8 with front wearing plate 6, rear pump cover 12.Described forward and backward wearing plate 6,8 underpart by locating stud 5 separately correspondence be contained on forward and backward pump cover 4,12, to prevent the rotation of forward and backward wearing plate.The opening portion of described front pump cover 4 also is connected to pipe nipple 1, between front pump cover 4 and pipe nipple 1, wound gasket 28 is housed, with installation and the anti-leak that is conducive to front pump cover.
