Abstract

The utility model relates to a self-priming front-mounted pump with high suction lift, and is structurally characterized in that the lower end of a cylinder shaped guide shell is air-tight fixedly connected with a cylinder shaped water suction casing. A non-return valve is installed at the suction inlet in the water suction casing. The upper end of the guide shell is air-tight fixedly connected with a pump body. The lateral surface of the pump body is provided with a water outlet which is connected with a multistage centrifugal pump. The upper end of the pump body is connected with a bearing body. The upper end of the bearing body is connected with a motor pedestal. A motor which is connected with a shaft coupling by a pump shaft is fixed on the motor pedestal. A water bearing and a bearing are installed respectively in the guide shell and the bearing body. The pump shaft is installed in the two bearings. The lower end of the pump shaft is provided with a spiral shaped induction wheel. After the pump is air-tight connected with the multistage centrifugal pump, the motor can drive the induction wheel to rotate, and the non-return valve unseals automatically so that the water can be pumped. Thanks to the high speed rotation of the spiral shaped induction wheel and the cooperation usage of the non-return valve, the self-priming front-mounted pump heightens the suction lift, realizes good self-priming effect, is not easy to generate cavitation erosion phenomenon, prolongs the service life of the pump, and guarantees the application effect.

Description

High suction depth self-priming front-mounted pump
One, technical field
The utility model relates to a kind of water pump, especially a kind of high suction depth self-priming front-mounted pump.
Two, background technique
Current, the big flow draining pump majority that the mine is used is a multistage centrifugal pump.Though the multistage centrifugal pump water displacement is big, deficiency is the self-priming weak effect, and the suction journey is low, and it is 4~5 meters that standard atmosphere is depressed the suction journey, influences the using effect of water pump, and in using cavitation takes place easily, makes the shortening in working life of pump.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this utility model provides a kind of and the matching used high suction depth self-priming of multistage centrifugal pump front-mounted pump, can effectively solve many deficiencies of multistage centrifugal pump.
Realize that the technological scheme that the purpose of this utility model adopts is: this high suction depth self-priming front-mounted pump mainly is made up of water absorbing section, guide shell, the pump housing, one-way valve, inducer, pump shaft, bearing, coupling and motor; The cylinder type water absorbing section that has been sealedly and fixedly connected, the lower end of cylinder type guide shell, one-way valve is equipped with at suction port place in the water absorbing section, the upper end of the guide shell pump housing that has been sealedly and fixedly connected, there is the water outlet that joins with multistage centrifugal pump the side of the pump housing, the upper end of the pump housing is connected with bearing support, the upper end of bearing support is connected with motor cabinet, is fixedly connected with motor on the motor cabinet; Water middle (center) bearing and bearing are housed respectively in described guide shell, the bearing support, pump shaft is housed in the two bearings, the lower end of pump shaft is fixed with the screw type inducer, and the upper end of pump shaft is connected with motor by coupling.Motor operation drove the inducer rotation after this pump and multistage centrifugal pump were tightly connected, and the automatic unlatching of one-way valve can absorb water.
The beneficial effects of the utility model are: because at a multistage centrifugal pump front complement high suction depth self-priming front-mounted pump, being used of screw type inducer high speed rotating in the front-mounted pump and one-way valve, just can increase the suction journey, realize good self-priming effect, and be difficult for taking place cavitation, prolong the working life of pump, guaranteed using effect.
Four, description of drawings
Fig. 1 is the utility model high suction depth self-priming front-mounted pump sectional structure chart.
Five, embodiment
In the accompanying drawings, the utility model high suction depth self-priming front-mounted pump mainly is made up of water absorbing section, guide shell, the pump housing, one-way valve, inducer, pump shaft, bearing, coupling and motor; The cylinder type water absorbing section 13 that has been sealedly and fixedly connected, the lower end of cylinder type guide shell 12, one-way valve 1 is equipped with at the suction port places in the water absorbing section 13, and the effect of one-way valve 1 is suction when opening, and prevents the aqueous reflux in the pump when closing, and realizes self-priming; The upper end of guide shell 12 pump housing 5 that has been sealedly and fixedly connected, there is the water outlet 11 that joins with multistage centrifugal pump the side of the pump housing 5, and the upper end of the pump housing 5 is connected with bearing support 6, and the upper end of bearing support 6 is connected with motor cabinet 7, is fixedly connected with motor 8 on the motor cabinet 7; Water middle (center) bearing 3 and bearing 10 are housed respectively in described guide shell 12, the bearing support 6, pump shaft 4 is housed in the two bearings, the lower end of pump shaft 4 is fixed with screw type inducer 2, and the upper end of pump shaft 4 is connected with motor 8 by coupling 9.Screw type inducer 2 can increase the suction journey of pump.Motor operation drove the inducer rotation after this pump and multistage centrifugal pump were tightly connected, and the automatic unlatching of one-way valve can absorb water, and depressed water pump suction journey at standard atmosphere and can reach 9 meters.
