The setting of plate can reduce influence of the fluid to auxiliary stator, so as to lift service life.
Further set：Delivery port in first water cavity is staggered with the delivery port position in the second water cavity.
By using above-mentioned technical proposal, the delivery port in the first water cavity is interlocked with the delivery port position in the second water cavity
The fluid that setting can discharge out circumferencial direction delivery port interlocks, so as to axial force is decomposed in more direction, further
Reduce the axial force that impeller is subject to.
Further set：The cross section of the blade is " V "-shaped to be set, the impact direction of its opening direction dorsad current
Set, blade center position is provided with fixed plate, and fixed plate is perpendicular to auxiliary stator and is fixed on auxiliary stator.
By using above-mentioned technical proposal, blade is " V "-shaped, and its opening direction deviates from the impact direction of current, because
It can be held when this current is to blade percussion to both sides three, so that resistance when reducing rotation, reduces the possibility of blade damage.
Further set：Dorsad central cover protrusion is set for first cover plate and the second cover plate central position.
By using above-mentioned technical proposal, water inlet can accommodate more fluids when rotated, more so as to make
Fluid enters in impeller, reaches more preferable drainage effect.
Preferably, the delivery port quantity in first water cavity and the second water cavity is between 5~8.
By using above-mentioned technical proposal, delivery port, which is arranged between 5~8, can increase the quantity of delivery port, from
And reduce the impact that every piece of blade is born, further reduce the impaired possibility of blade.
Another object of the present utility model is to provide a kind of energy-efficient customization water pump, and it has the blade of impeller not rapid wear
It is bad, service life length, energy-efficient advantage.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of energy-efficient customization water pump, including the pump housing and pump shaft, also with above-mentioned any one centrifugal pump enclosed leaf
Wheel.
In summary, the utility model has the advantages that：
Discharging water is carried out by the runner of two and the above, axial force and the radial load drop that impeller cover and blade are subject to
Low, the Fluid Volume of dispatch is greatly increased, with bigger centrifugal force, additionally it is possible to save the energy, is made it have higher fluid and is carried
Rise efficiency.
