Description
The utility model relates to a kind of self filling type jet pump, is specially adapted to the deep-well operation of pumping up water.
Before the utility model is made, still useless on the market in the pump up water big flow self filling type jet pump of operation of deep-well.Chinese patent CN1067946A disclosed " jet pump " is a kind of pump chamber with transfer valve and expulsion valve that comprises, pumping cylinder and pump plug, shaft-like manipulation hand lever, and the streamwise that links to each other with pumping cylinder is arranged on the suction pipe in the pump chamber, pumping cylinder is by the relative movement of pump plug, to realize a kind of hand jetting pump of pump process.This jet pump can only be as a kind of treegarden irrigation spraycan and flushing tool, and can not be as the deep-well operation of pumping up water.
In view of the problem of above-mentioned existence, it is big that the purpose of this utility model provides a kind of flow, is specially adapted to the pump up water jet pump of filling certainly of operation of deep-well.
The purpose of this utility model is achieved like this: the motor part of self filling type jet pump is become electromechanical integrated structure with pump housing partial design.On the pump housing, be provided with pressurized tank, in pump chamber, be provided with receded disk impeller, and being equipped with ejectisome and outflow cover for water, the nozzle on the ejectisome can improve the inflow that enters receded disk impeller effectively, thereby has strengthened the flow and the outlet pressure of irritating jet pump certainly effectively.
Through the jet pump structure of the filling certainly compactness after the above-mentioned design, flow is big, lift is high.Owing to added pressurized tank on the pump housing, can regulate the pressure in the pipeline automatically, with the number of times of minimizing frequent motor starting, thereby improved effectively the working life of irritating jet pump certainly.
Specific embodiments of the present utility model as shown in drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of the pump housing of the present utility model
Fig. 3 is the structural representation of impeller of the present utility model
Fig. 4 is the side diagrammatic sketch of impeller of the present utility model
Fig. 5 is the structural representation of runner body of the present utility model
Fig. 6 is the utility model structure of nozzle schematic representation
Below in conjunction with accompanying drawing, concrete structure of the present utility model and working principle and working procedure are elaborated:
Adopt electromechanical integrated structure from irritating jet pump, it mainly includes parts such as motor 1, pressurized tank 3, pump seat 4, the pump housing 10, impeller 5, ejectisome 8, pressure switch 14, pressure gauge 15.Pump seat 4 is made one with the motor front cover, and pump seat 4 and the pump housing 10 be common to constitute water pump pump chambers 9, and impeller 5 is arranged on the motor shaft 16 in the pump chamber 9 by sealing Figure 17.At the front end of impeller 5, be provided with outflow cover for water 7, outflow cover for water 7 is connected with ejectisome 8.On the pump housing 10, be provided with water inlet 11 and osculum 18.Pressurized tank 3 is installed in osculum 18 places of the pump housing 10 by outlet pipe 6.In pressurized tank 3, be provided with air bag 2, air bag 2 adopts whippy rubber to make, to regulate the pressure in the pump housing and the pipeline.Adopt enclosed construction from the impeller 5 of irritating jet pump.In impeller 5, be provided with helical blade 21.The water intake 19 of impeller is axial setting, and 20 of its water outlets are radial arrangement.Be arranged in the outflow cover for water 7 of front end of impeller 5, also be provided with spiral water outlet.The ejectisome 8 that is installed on the outflow cover for water 7 was made up of runner body 12 and nozzle in 13 years.The inner chamber of runner body 12 is horn-like structure, and nozzle 13 is installed on the nozzle carrier 22 of runner body.The pressure gauge 15 and the pressure switch 14 that are arranged on the pump housing 10 can show in the pump and the pressure in the pipeline automatically, and the unlatching of automatically controlled water pump.
Adopt the aluminum thin walled structures from the motor case of irritating jet pump, to alleviate its overall weight.The cooling fan of motor adopts the major diameter fan blade, can improve its cooling effect effectively.Between motor fan housing and the motor case, then adopt the cassette structure, make it have good dismounting performance.
Be achieved like this from the working principle and the working procedure of irritating jet pump: add diversion in earlier with pump chamber and pipeline, then motor is connected power supply, motor 1 impeller 5 high speed rotating, produce suction, by intake pipe water is sucked from the water inlet 11 on the pump housing 10, and through runner body 12, enter in the impeller 5, under impeller high speed rotating action of centrifugal force, produce pressure, the spiral water outlet of press water on impeller and outflow cover for water 7, the inflow pump intracoelomic cavity, and be divided into two strands, osculum 18 on the one stock-traders' know-how pump housing is discharged by outlet pipe 6; Another strand press water is back to ejectisome, by 13 ejections of the nozzle on the ejectisome, through runner body 12, enters impeller 5 once more, to improve the water feeding pressure of impeller, reaches the purpose of supercharging.
Be installed in the rubber pneumatic bag 2 in the pressurized tank 3 on the outlet pipe 6, be filled with the air of 0.25～0.3MPa usually.When pressure was arranged, press water can enter in the pressurized tank.Behind supply disconnecton, when hydraulic pressure descends, because the effect of rubbery human body internal pressure gas, the water that pressure side is arranged in the pressurized tank squeezed get back in the pump housing and the pipeline, stablizing in the pump housing and the pipeline, and the hydraulic pressure of pressure switch, the assurance pressure switch is worked reposefully, and realizes the purpose of automatic water-supply.
