Abstract
The utility model relates to a dual-purpose self-priming pump, comprising a diving electric motor, an impeller and a pump body which is divided into a water intake cabin, a water outflow cabin and an impeller cell. A jet pump is arranged between the water intake cabin and the water outflow cabin which are arranged at the lower part of the pump body; the outlet port of the jet pump is communicated with the inlet port of the impeller cell through the water outflow pipe of the jet pump and the inlet port of the jet pump is communicated with the inlet port of the pump; the inlet port of the nozzle of the jet pump is communicated with the water outflow cabin of the pump body. The utility model can be used on water or under water, saving the trouble of adjusting the position of the pump frequently, therefore the utility model is widely applicable and is convenient to use.
Description
Affiliated technical field
The utility model relates to a kind of liquid pump, the dual-purpose water pump of particularly a kind of diving self-priming.
Background technique
The existing submersible type water pump that uses uses double shrouded wheel centrifugation pumping structure usually, rotates generation centrifugal force by the direct impeller of submersible motor and draws water, owing to do not inhale journey, can only use under water, when drawdown, should be the timely dive of water pump, otherwise can not use, some regional level of ground water are low, SEA LEVEL VARIATION is big, and the WIH position is higher during rainy season, and the well head water level is extremely low during dry season, therefore, for making the water pump proper functioning, must in time adjust water pump location, it is very inconvenient to use.
Summary of the invention
The purpose of this utility model provides a kind of novel water pump that can dive under water and have certain suction journey, is applicable to that particularly the water source drop changes the dual-purpose water pump of diving self-priming that use in place greatly.
The utility model is achieved in that the dual-purpose water pump of a kind of diving self-priming, comprise submersible motor, impeller and the pump housing, it is characterized in that being divided into water storage in the pump housing, go out sump and impeller active chamber, pump housing bottom water storage and go out to be provided with a Jet injector between the sump, the water outlet of Jet injector is communicated with impeller active chamber water intake by the Jet injector outlet conduit, the Jet injector water intake is communicated with pump intake, and the nozzle water intake and the pump housing of Jet injector go out sump and be communicated with.
The described impeller active chamber and the pump housing go out to be provided with guide plate between the sump, and its top is provided with the guiding gutter more than three or three, and guide plate cooperates with wheel rotation, and guide plate is communicated with the sump that goes out of the pump housing with the guiding gutter outlet.
Described impeller blade number is identical with guiding gutter quantity on the guide plate.
The beneficial effects of the utility model are: compare with common submersible pump, can save the trouble of frequent adjustment water pump location in the water surface or use under water, wide accommodation uses convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model cross-sectional schematic;
Fig. 2 is a deflector structure schematic representation among the utility model embodiment;
Fig. 3 is the A-A sectional view of Fig. 2.
1. submersible motors in the accompanying drawing, 2. impeller, 3. guide plate, 4 pump housings, 5. guiding gutter, 6. motor housing, 7. pump housing water outlet, 8. pump housing water intake, 9. the Jet injector water intake, 10. Jet injector nozzle, 11. Jet injector outlet pipes, 12. machine shafts, 13. go out sump, 14. impeller active chambers, 15. Jet injector water outlets, 16. water storages.
Embodiment
With reference to Fig. 1,2,3, the dual-purpose water pump of diving self-priming is mainly by submersible motor 1, impeller 2, guide plate 3, the pump housing 4 formations such as grade, impeller 2 is fixed on the machine shaft 12, the pump housing 4 is connected in aggregates with motor housing 6 usefulness bolts, be divided into water storage 16 in the pump housing 4, go out sump 13 and impeller active chamber 14, at water storage 16 with go out between the sump 13 to be provided with Jet injector, the outlet pipe 11 of Jet injector is communicated with impeller intake, the water intake 9 of Jet injector is communicated with pump intake 8, the water intake of Jet injector nozzle 10 goes out sump 13 with the pump housing and is communicated with, and the spout of nozzle is communicated with over against Jet injector water outlet 15 and with it.
Described guide plate 3 is arranged at impeller and the pump housing goes out between the sump 13, and guide plate 3 is rotatably assorted with impeller 2, and its top has the guiding gutter 5 identical with the impeller blade number, and guiding gutter 5 one ends are communicated with impeller blade, and an end is communicated with the sump 13 that goes out of the pump housing.During use, water pump places on the normal water level position, can be positioned at the water surface or, pump intake 8 is connected with intake pipe under water.The length of intake pipe is no more than water pump and inhales journey, pump outlet 7 is connected with outlet conduit, during work, the direct impeller 2 of machine shaft is rotated, current by water intake 8 and Jet injector nozzle 10 in Jet injector outlet conduit 11 intake impellers 2, impeller pressurization through high speed rotating, be pressed into out sump 13 by guiding gutter 5, the pressure flow major part that goes out sump is delivered to outside the pump housing through water outlet 7, and a part forms circulation through the jet source of nozzle 10 as Jet injector in pump, because of Jet injector nozzle 10 is connected with Jet injector water intake 9, injection by jet source becomes vacuum in nozzle profile, and water storage forms negative pressure, the water source is because barometric pressure effect automatic stream water storage 16, increase water pump and inhale journey, guarantee that water pump still can proper functioning than low water level the time, improved labor aptitude.
Among the embodiment described in the utility model, the opening number of guiding gutter is five, and is identical with the impeller blade number, can reduce the pressure loss of current, improves water outlet efficient.The pump sump lift is in 10 meters, during dry season, as long as level of ground water is within pump head, but the water pump proper functioning is during rainy season, even water pump is submerged in the water, also can guarantee the proper functioning of water pump, remove frequent adjustment water pump location from, use conveniently, be adapted to especially as the bigger deep well water pump of WATER LEVEL CHANGES.
