Abstract
The utility model relates to a centrifugal pump which comprises a motor, a pump body, an impeller and a pump shaft, wherein the pump shaft and the pump body are sealed by the structure of a V-shaped sealing ring which comprises a supporting ring, a sealing ring, a pressing ring and a pressing cover. The pump shaft and the pump body of the centrifugal pump are sealed by the structure of the V-shaped sealing ring, and thus the utility model has the advantages of simple structure, low cost and service life extension. When the phenomenon of water leakage appears, the goal of no water leakage can be obtained by tightly pressing the pressing cover; the utility model has particularly good sealing performance when conveying media containing sundries.
Description
The utility model relates to a kind of centrifugal pump, especially the black box on the centrifugal pump.
Centrifugal pump generally comprises motor, the pump housing, impeller and pump shaft.And the existing centrifugal pump of the sealing between the pump shaft and the pump housing generally adopts stuffing box structure and mechanical seal structure.
Adopt stuffing box structure, because packing is inhomogeneous to the pressure of axle, thus the degree of wear difference of packing, so working life is not long, by asbestos packing, the operating time of a dish will leak less than two months; And the mechanical seal this respect is better relatively, and is high but the mechanical seal cost is wanted relatively, and if have foreign material in the medium then mechanical seal is damaged, thereby leak.
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and a kind of centrifugal pump is provided, the black box good seal performance between its pump shaft and the pump housing, and long service life, simple in structure, cost is low.
The utility model comprises motor, the pump housing, impeller and pump shaft, adopts the V-shaped seal ring structure to seal between the pump shaft and the pump housing, and it comprises supporting ring, seal ring, pressure ring and gland.
Owing to adopted the V-shaped seal ring structure between its pump shaft of centrifugal pump described in the utility model and the pump housing, simple in structure, cost is low, and improve working life greatly, when water leakage phenomenon occurring, only need compress gland and a little just can reach the not purpose of full water, and the utility model is good especially to the medium-tight performance that conveying contains foreign material.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1: the configuration diagram of present embodiment;
Fig. 2: the schematic representation of the V-shaped seal ring structure between the pump shaft and the pump housing.
The utility model comprises motor 1, the pump housing 2, impeller 3 and pump shaft 4, adopts the V-shaped seal ring structure to seal between the pump shaft 4 and the pump housing 2, and it comprises supporting ring 5, seal ring 6, pressure ring 7 and gland 8.Gland is the gland screw in the present embodiment, and gland screw and the pump housing are for being threaded.
Claims (2)
1, a kind of centrifugal pump comprises motor, the pump housing, impeller and pump shaft, it is characterized in that; Between the pump shaft (4) and the pump housing (2), adopt the V-shaped seal ring structure to seal.
2, centrifugal pump according to claim 1 is characterized in that: described V-shaped seal ring structure comprises supporting ring (5), seal ring (6), pressure ring (7) and gland (8).
