Abstract
The utility model relates to a centrifugal pump, in particular to a vertical multistage deep-well centrifugal pump. The vertical multistage deep-well centrifugal pump comprises a pump cylinder, wherein a water inlet is arranged at the bottom end of the pump cylinder, a water outlet is arranged at the top end of the pump cylinder, a lower bracket and an upper bracket are arranged in the pump cylinder, a pump shaft is arranged on the lower bracket and the upper bracket, a motor is arranged at the bottom end of the pump shaft, a plurality of impellers are arranged on the pump shaft, a water outlet valve is arranged at the top end of the pump shaft and is communicated with the water outlet, and a check valve is arranged on the water outlet valve. The number of the impellers is forty. The vertical multistage deep-well centrifugal pump is slender and can be placed in a deep well with a smaller wellhead aperture to pump groundwater; as the impellers are arranged on the pump shaft, the shape of a multistage pump is formed, and the liquid capacity can be larger, so that the vertical multistage deep-well centrifugal pump has a higher lift; and additionally, the check valve is arranged at an outlet, the water hammer pressure can be relieved.
Description
Technical field
The utility model is a kind of centrifugal pump, particularly a kind of vertical multi-stage centrifugal pump for deep well.
Background technique
Common centrifugal pump is through aqueduct centrifugal pump to be connected with the water source during use, through centrifugal pump bigcatkin willow is arrived eminence again.Because the relation of atmospheric pressure, the height difference between water source and the centrifugal pump can not be too big, and groundwater recession is a lot of now, so Ordinary Centrifugal Pumps has not been suitable for current situation.
Summary of the invention
The purpose of the utility model is in order to solve the situation that Ordinary Centrifugal Pumps is not suitable for current groundwater recession, to invent a kind of vertical multi-stage centrifugal pump for deep well that can be used for the deep-well water lift.
The purpose of the utility model realizes as follows: said vertical multi-stage centrifugal pump for deep well, comprise a pump barrel, and the bottom of pump barrel is provided with water intake; The top of pump barrel is provided with water outlet, is provided with lower support frame and upper bracket in the pump barrel, and pump shaft is located on lower support frame and the upper bracket; The bottom of pump shaft is provided with motor, and pump shaft is provided with a plurality of impellers, and the top of pump shaft is provided with outlet valve; Outlet valve is communicated with water outlet, and outlet valve is provided with check valve.
Said a plurality of impeller is 40.
The good effect of the utility model is following: the utility model is an elongated shape; Can put into the less deep-well in well head aperture and draw underground water,, constitute the form of multistage pump because pump shaft is provided with a plurality of impellers; Make liquid obtain bigger capacity; Therefore have higher lift, add in the outlet port and be provided with check valve, can alleviate water hammer pressure.

9, outlet valve; 10, check valve.
Embodiment
As shown in Figure 1, said vertical multi-stage centrifugal pump for deep well comprises a pump barrel 1; The bottom of pump barrel 1 is provided with water intake 2, and the top of pump barrel 1 is provided with water outlet 3, is provided with lower support frame 4 and upper bracket 5 in the pump barrel 1; Pump shaft 6 is located on lower support frame 4 and the upper bracket 5, and the bottom of pump shaft 6 is provided with motor 7, and pump shaft 6 is provided with a plurality of impellers 8; The top of pump shaft 6 is provided with outlet valve 9, and outlet valve 9 is communicated with water outlet 3, and outlet valve 9 is provided with check valve 10.
Said a plurality of impeller 8 is 40.
The utility model is an elongated shape; Can directly put into the less deep-well in well head aperture and draw underground water,, constitute the form of multistage pump because pump shaft is provided with a plurality of impellers; It is 40 multistage that progression can reach for a long time; Under the drive of power source, reach the purpose of carrying liquid, adopt multi-stage impeller to make liquid can obtain bigger capacity thereby make liquid produce kinetic energy through the receded disk impeller rotation.Therefore have higher lift, add in the outlet port and be provided with check valve, can alleviate water hammer pressure.
