Abstract
The utility model provides a centrifugal pump with a filter crushing device, which comprises a pump body (1), a pump shaft (2), a pump cover (3) and an impeller (4), wherein the liquid inlet of the pump is provided with an inlet filter mantle (5); the circumferential surface at the inlet end of the impeller of the inlet filter mantle (5) is provided with a plurality of holes; the pump cover (3) is provided with an outlet filter mantle (6) near the outlet end of the impeller; and the circumferential surface of the outlet filter mantle (6) is provided with a plurality of holes. According to the structure adopted by the utility model, a medium is foreground through the filter mantle at the inlet end of the impeller before entering an impeller runner, and then, the granular medium is further thinned through the filter mantle at the outlet end of the impeller, and thereby, the medium conveying condition is improved, the abrasion is reduced, and the service lives of the pump and a shaft seal can be prolonged.
Description
Technical field
The utility model relates to a kind of equipment for liquid transportation, and is particularly a kind of with the centrifugal pump that filters reducing mechanism.
Background technique
Centrifugal pump is according to the centrifugal principle design, and the impeller blade drive medium rotation by high speed rotating throws away medium, thereby reaches the purpose of conveying.Centrifugal pump mainly comprises the pump housing, pump cover, axle, bearing support and shaft sealer.Behind pump startup, impeller drives high-speed rotation by axle, and interlobate liquid also must be along with rotation.Under action of centrifugal force, liquid is thrown to outer rim and is obtained energy from the impeller center, gets into pump case to leave impeller outer edge at a high speed.When liquid flows to outer rim by the impeller center, in impeller, be formed centrally certain vacuum, liquid just is pressed in the impeller continuously, constantly is inhaled into and discharges.,, conveying stops up when containing the impurity particle medium for pump through regular meeting, the serious wear of mechanical seal sealing surface, and the medium transport situation is undesirable, thereby has influenced the working life of pump.
The model utility content
The purpose of the utility model provide a kind of can pulverized particles, the band that improves the medium transport situation filters the centrifugal pump of reducing mechanism.
The purpose of the utility model realizes as follows: a kind of with the centrifugal pump that filters reducing mechanism; Comprise the pump housing, pump shaft, pump cover and impeller; Be provided with the ingress filtering cover at described pump liquid entering hole; Impeller eye end place circumferential surface at the ingress filtering cover is established some holes, on described pump cover, is provided with the egress filtering cover near impeller outlet end place, establishes some holes on the egress filtering cover circumferential surface.
The structure that the utility model adopts, medium is crossed filter ruffle through impeller eye end place and is ground in advance before getting into blade passage; Filter through impeller outlet end place again and pack into the step refining granule medium; Improve the medium transport situation, reduce wear, thereby can prolong working life of pump.
Description of drawings
For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein:
Accompanying drawing is depicted as the structural representation of the utility model
Among the figure: 1, the pump housing 2, pump shaft 3, pump cover 4, impeller 5, ingress filtering cover 6, egress filtering cover
Embodiment:
With reference to accompanying drawing; A kind of with the centrifugal pump that filters reducing mechanism; Comprise the pump housing 1, pump shaft 2, pump cover 3 and impeller 4, be provided with ingress filtering cover 5, establish some holes at the impeller eye end place circumferential surface of ingress filtering cover 5 at described pump liquid entering hole; On described pump cover 3, be provided with egress filtering cover 6 near impeller outlet end place, egress filtering overlaps establishes some holes on 6 circumferential surfacies.
The utility model impeller 4 drives high-speed rotation by pump shaft 2, and under action of centrifugal force, medium is thrown to outer rim and obtained energy, gets into pump case to leave impeller 4 outer rims at a high speed.Medium grinds through the perforate of the ingress filtering cover 5 at impeller eye end place before getting into blade passage in advance, and the further refinement granule medium of perforate of egress filtering cover 6 through impeller outlet end place can improve the medium transport situation again, reduces wear.
Above-described specific embodiment; Purpose, technological scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (1)
1. one kind with the centrifugal pump that filters reducing mechanism; Comprise the pump housing, pump shaft, pump cover and impeller; It is characterized in that: be provided with the ingress filtering cover at described pump liquid entering hole; Impeller eye end place circumferential surface at the ingress filtering cover is established some holes, on described pump cover, is provided with the egress filtering cover near impeller outlet end place, establishes some holes on the egress filtering cover circumferential surface.
