Abstract
The invention discloses a water pump which comprises a vane wheel and a shell body containing the vane wheel. The vane wheel is provided with multistage vanes along an axial direction, and the radius of the vanes are unequal along the axial direction of the vane wheel. A water inlet is arranged on the shell body in the vane wheel axial direction, and a water outlet is arranged in the radial direction of the vane wheel. According to the water pump, the vanes of the vane wheel are arranged in a multistage mode, and the radius of the vanes are unequal along the axial direction of the vane wheel, the pressure and flow speed of fluid are changed through each stage of vanes, the pressure of the water outlet is changed up to usage requirement after multistage changes, and the efficiency of the water pump is equivalently improved.
Description
Technical field
The present invention is a kind of water pump.
Background technique
Water pump is a kind of machinery of carrying liquid or making the liquid supercharging, in order to improve better the kinetic energy of carrying liquid, increase in other words the pressure of liquid, need to increase the rotating speed of water pump vane or the torque that increases impeller, as increase the radius of impeller, the most common mode is the blade quantity that changes impeller at present, being about to blade makes up, use a plurality of blade layering settings, reach raising hydraulic pressure, but this mode adopts the blade of same radius to consist of, and has increased the output energy of line shaft, can not improve pump efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of water pump, solve the existing not high problem of pump efficiency.
Purpose of the present invention is come specific implementation by the following technical programs: a kind of water pump, comprise impeller and the housing that holds impeller, this impeller is provided with multistage blade vertically, the radius of described multistage blade upwards is being what do not wait along impeller shaft, upwards be provided with water inlet at impeller shaft on the housing, and directly upwards be provided with water outlet at impeller.
Further, described multistage blade with liquid along the flow direction of impeller shaft for reducing successively.
Further, described multistage blade with liquid along the flow direction of impeller shaft for increasing successively.
Further, be provided with guide plate between the described multistage blade.
Water pump of the present invention is made as the blade on the impeller multistage, radius along from impeller shaft to upper blade is not wait simultaneously, every grade blade changes pressure or the flow velocity of fluid, so that the pressure of water outlet more meets user demand, is equivalent to improve pump efficiency after multistage change.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structural drawing of the described water pump of the embodiment of the invention.
Embodiment
As shown in Figure 1, the described water pump of the embodiment of the invention comprises impeller 1 and the seal casinghousing 2 that holds impeller 1, and this impeller 1 is provided with multistage blade 11 in the direction along impeller shaft, this multistage blade 11 is not wait at radius vertically, and the radius of namely axially going up adjacent blades is different; On housing 2 along impeller 1 axially be provided with water inlet 21, upwards set out the mouth of a river 22 along the footpath of impeller 1.
In the water pump shown in Fig. 1, blade 11 be with liquid along the flow direction of impeller shaft for increasing successively, water outlet 22 is located at the blade place of maximum radius; Opposite, blade 11 can be set be with liquid along the flow direction of impeller shaft as reducing successively, and water outlet 22 can be located at the blade place of least radius.Adopt above-mentioned two kinds of blade constituted modes, can increase the pressure of entry of the blade of water outlet, what be equivalent to increase water pump goes out water kinetic energy or pressure, has improved pump efficiency.
Better mode is that guide plate 3 is set between each grade blade, and namely the current of previous stage blade supercharging by the low pressure place of drainage to the next stage blade, have avoided current disorderly through guide plate 3, can further improve pump efficiency.
Claims (4)
1. water pump, comprise impeller and the housing that holds impeller, it is characterized in that: this impeller is provided with multistage blade vertically, and the radius of described multistage blade upwards is being what do not wait along impeller shaft, upwards be provided with water inlet at impeller shaft on the housing, and directly upwards be provided with water outlet at impeller.
