Abstract
The utility model relates to a centrifugal pump, which mainly comprises a hand pump, a pump body, a bracket and a belt pulley, wherein a handle is positioned on the upper part of the hand pump and the hand pump is connected with the pump body and a water inlet pipe through a tee joint pipe which is provided with a check valve inside. The pump body is provided with an impeller inside. One end of a pump shaft is fixed on the impeller. A rear cover is arranged near the impeller and in the bracket and is fixed on the pump shaft simultaneously. The bracket is connected with the pump body. The pump shaft is fixed with a bearing too. The belt pulley is fixed on the other end of the pump shaft. A water outlet pipe is connected with the pump body. A check valve is arranged on the water outlet pipe. The utility model has simple structure and solves the problem of the supply of water by the press of hands through adding two check valves in the water inlet pipe and the water outlet pipe when the pump is started for pumping water every time, man power is saved and the work efficiency of the utility model is increased.
Description
Technical field: the utility model relates to a kind of centrifugal pump, especially a kind of being applied on the agricultural, the centrifugal pump of the usefulness of drawing water.
Background technique: the suction pump of using in vast rural irrigation at present, when each the use, all to carry out water on the hand, special under the lower situation of water level, water all will carry out long time on each hand, and working efficiency is very low, and effort.
Summary of the invention: at above-mentioned the deficiencies in the prior art, the utility model provides a kind of improved centrifugal pump, only needs when using for the first time water on the hand, as long as centrifugal pump does not leave well, just can directly use later, need not water on the hand.
Technological scheme: centrifugal pump mainly comprises: hand pump (1), the pump housing (3), support (7) and belt pulley (9).Handle (13) is positioned at the top of hand pump (1), and hand pump (1) links to each other with the pump housing (3), intake pipe (12) by three-way pipe, is provided with safety check (11) in the intake pipe (12).Be provided with impeller (2) in the pump housing (3), an end of pump shaft (10) is fixed on the impeller (2), and the next door of impeller (2) is provided with bonnet (4).Bonnet (4) places in the support (7), also is fixed on the pump shaft (10) simultaneously.Support (7) links to each other with the pump housing (3).Also be fixed with bearing (8) on the pump shaft (10).Belt pulley (9) is fixed on the other end of pump shaft (10).Outlet pipe (5) links to each other with the pump housing (3).Safety check (6) places in the outlet pipe (5).
The utility model is simple in structure, has just added two safety check in intake pipe and outlet pipe, draws water and all wants the problem of water on the hand with regard to having solved each primer pump, has saved manpower, has improved working efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in Figure 1, centrifugal pump mainly comprises: hand pump 1, the pump housing 3, support 7 and belt pulley 9.Handle 13 is positioned at the top of hand pump 1, and hand pump 1 links to each other with the pump housing 3, intake pipe 12 by three-way pipe, is provided with safety check 11 in the intake pipe 12.Be provided with impeller 2 in the pump housing 3, an end of pump shaft 10 is fixed on the impeller 2, and the next door of impeller 2 is provided with bonnet 4.Bonnet 4 places in the support 7, also is fixed on the pump shaft 10 simultaneously.Support 7 links to each other with the pump housing 3.Also be fixed with bearing 8 on the pump shaft 10.Belt pulley 9 is fixed on the other end of pump shaft 10.Outlet pipe 5 links to each other with the pump housing 3.Safety check 6 places in the outlet pipe 5.
Working principle: during use, depress handle 13 repeatedly, because atmospheric effect, water in the well will back down safety check 11, enter in the intake pipe 12 and the pump housing 3, starting electrical machinery drove belt pulley 9 by belt and rotated this moment, thereby impeller 2 is rotated, and water will constantly be discharged in outlet pipe 5.Work as disable motor, when impeller 2 stopped operating, safety check 11 and safety check 6 will fall, and water can not flowed back in the well, thereby had kept consistent with the air pressure in the well in the pump.When starting centrifugal pump once more, need not water on the hand, just can directly draw up water come.
