The invention discloses a new water pump, comprising a water hole, a diverter, a blade wheel and a motor. The invention can be used in variable water pumps, to effectively improve the effective work, reduce the power of motor, reduce the productive material consumptions and reduce the cost.

Description

A kind of novel water pump

Technical field

The present invention relates to a kind of water pump, be specifically related to a kind of novel submersible pump.

Background technique

At present existing all kinds of water pumps are because the excesssive gap between impeller and pump housing shell certainly exists the backwater energy loss; And often improve lift and water-outlet quantity by increasing impeller progression, therefore, on the one hand thereby later each impeller in the second level all must be to the mobile formation resistance of water in the current way, thereby drives and further cause energy loss along with impellers at different levels rotate outer power on the other hand.The present invention mainly designs at existing water pump idle work proportion shortcoming big, that energy consumption is too high.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure, energy-conservation, a kind of novel water pump efficiently.

Technological scheme of the present invention is: a kind of novel water pump, comprise osculum, the fluid director assembly, impeller assembly and electric machine assembly, it is characterized in that described fluid director assembly is installed in the below of osculum, the impeller assembly is installed in the below of fluid director assembly, electric machine assembly is installed in the below of impeller assembly, described fluid director assembly comprises fluid director and impeller shaft bearing, described fluid director comprises guide plate, axis and fluid director chamber, described impeller assembly comprises impeller, blade wheel chamber and bearing, described impeller comprises impeller shaft, blade and impeller and fluid director connection bearing, impeller and fluid director are connected by bearing, guide plate is worked in coordination with impeller and is connected, the guide plate tip is blade-like and parallels with blade, guide plate is suitable angle and radian, the blade tip is flush, the blade tip is widened the identical sealed shape that almost is with water pump tube wall radian, blade is 4, blade shape is a dish, two relative blade upper limbs pass the axle center and the blade upper limb also is blade-like and tip is an angle of 90 degrees point-blank, and lower edge stretches out downwards that seemingly dish is wing.

Described water pump tube wall uses backwater material and abrasive material.

Described width of blade can be increased to quadrant to two/circle.

Working principle of the present invention: water pump vane forms the effect of two kinds of power in the course of the work to current: a kind of is Driving force along the flow direction of water; Another kind is the rotating force along the sense of rotation of impeller, in the course of the work, when each blade of impeller when corresponding each guide plate meets at every turn, be deformed into one moment closed state, flowing water flow is formed an instantaneous pressure, after the impeller rotational speed acquires a certain degree, just reached the degree of complete closure between impeller and the guide plate, the effect of guide plate is exactly the whole pressure that carried water column, alleviated the suffered pressure of impeller, the rotation function of current is converted into mobile kinetic energy, so just, reached the purpose of the energy loss of stopping fully to conflux, be converted into mobile kinetic energy at rotation function like this with water, stop to reflux after the energy loss, the energy loss of the water pump of existing use almost reduces to zero, thereby realizes effectively improving pump head, energy-saving and cost-reducing target.

Advantage of the present invention:

1. the present invention adopts single impeller to add guide plate, and water pump makes current stop without any bar in flow process in pump process.

2. blade tip of the present invention is flush, and blade and pump body almost are sealed shape like this, reduces the backwater energy loss with this, and water is converted into mobile kinetic energy with the rotation function of wheel rotation immediately through the effect of guide plate, can improve pump head effectively.

3. the present invention can improve the manufactured materials consumption and the cost of production of water pump useful work proportion, reduction water pump mating power power of motor, reduction water pump, motor effectively.

Specific embodiment

According to specific embodiment the present invention is further specified below:

As depicted in figs. 1 and 2, a kind of novel submersible pump, comprise osculum 1, fluid director assembly 2, impeller assembly 3 and electric machine assembly 4, it is characterized in that described fluid director assembly 2 is installed in the below of osculum 1, impeller assembly 3 is installed in the below of fluid director assembly 2, and electric machine assembly 4 is installed in the below of impeller assembly 3.

As Fig. 2, Fig. 3 and shown in Figure 4, described fluid director assembly 2 comprises fluid director 5 and impeller shaft bearing 6, and described fluid director 5 comprises guide plate 10, axis 11 and fluid director chamber 12.

As Fig. 5, Fig. 6 and shown in Figure 7, described impeller assembly 3 comprises impeller 7, blade wheel chamber 8 and bearing 9, described impeller 7 comprises impeller shaft 13, blade 14 and impeller and fluid director connection bearing 15, impeller 7 is connected by bearing 9 with fluid director 5, guide plate 10 first connection bearings 15, impeller 7 is connected by bearing 9 with fluid director 5, guide plate 10 tips are blade-like and parallel with blade 14, guide plate 10 is suitable angle and radian, blade 14 tips are flush, blade 14 tips are widened the identical sealed shape that almost is with water pump tube wall radian, blade 14 is 4, blade 14 is shaped as dish, and two relative blade 14 upper limbs pass the axle center and blade 1 upper limb also is blade-like and tip is an angle of 90 degrees point-blank, and lower edge stretches out like dish wing downwards.

Working principle of the present utility model: water pump vane 7 forms the effect of two kinds of power in the course of the work to current: a kind of is Driving force along the flow direction of water; Another kind is the rotating force along the sense of rotation of impeller 7, in the course of the work, when each blade 14 of impeller 7 when corresponding each guide plate 10 meets at every turn, just formed one moment closed state, flowing water flow is formed an instantaneous pressure, after the impeller rotational speed acquires a certain degree, just reached the degree of complete closure between impeller 7 and the guide plate 10, the effect of guide plate 10 is the suffered pressure of impeller 7 that carried whole pressure relieves of water column, the rotation function of current is converted into mobile kinetic energy, so just, reached the purpose of the energy loss of stopping fully to reflux, be converted into mobile kinetic energy at rotation function like this with water, stop to reflux after the energy loss, the energy loss of the water pump of existing use almost reduces to zero, thereby realizes effectively improving pump head, energy-saving and cost-reducing target.The employing Multiple Sinking Pump is an example, the increase of the progression of water pump can not increase water-outlet quantity, also very little to the effect that increases pump head, the utility model adopts the single-stage impeller, when needs increase water-outlet quantity, blade can be increased to quadrant to two/circle, water-outlet quantity can reach maximum value after blade is increased to a certain degree, after this model utility practices, estimate that the mating power power of water pump can descend more than 50 percent.
