Fig. 2 is external structure schematic diagram of the present utility model.
Each reference character is, and: 1-is intake adapter, the 2-pump housing, 3-water-output flange, 4-impeller, 5-pump cover, 6-packing ring, 7-stuffing box packing, 8-Gland, 9-bearing support, 10-bearing, the porose end cap of 11-, 12-belt pulley, coverboard before 13-, 14-valve, 15-main shaft, 16-impeller protecgulum.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, shown in Fig. 2, the utility model discloses a kind of self-priming pump, comprise the pump housing 2, be located at the water inlet adapter 1 of the pump housing 2 front end and be located at the water-output flange 3 at the pump housing 2 top, the inner chamber of the pump housing 2 is separated into liquid storage room and gas-liquid separation chamber by partition panel, front coverboard 13 is provided with below partition panel, the described pump housing 2 is connected with bearing support 9 by pump cover 5, by bearing 10, main shaft 15 is installed in bearing support 9, main shaft 15 front end is fixed with the impeller 4 being positioned at gas-liquid separation indoor, main shaft 15 tail end is provided with belt pulley 12, the porose end cap 11 of end winding support of bearing support 9, described water inlet adapter 1 is provided with valve 14, impeller protecgulum 16 is provided with between described front coverboard 13 and impeller 4, the width of described impeller protecgulum 16 is less than the external diameter of impeller 4, the Gland 8 be fixed on pump cover 5 is provided with in described bearing support 9, main shaft 15 is provided with the packing ring 6 between pump cover 5 and Gland 8, packing ring 6 is provided with stuffing box packing 7.
The liquid storage cylinder of this self-priming pump is also communicated with pump work chamber by the return port of top and the circulation port of below, form the axis backflow external mixture type system of pump, after pump quits work, pump inner chamber has contained the liquid of a constant volume, when pump startup, liquid storage in pump is under the effect of impeller 4, be entrained with air upwards to dish out, liquid flows to active chamber by gas-liquid separation, and gas is discharged outside pump, make to form certain degree of vacuum in pump, reach the effect of self-priming.
