Brief introduction and technical specifications
1,Electric water pump application:


Definition of centrifugal pump :
Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic
energy of the fluid flow. The rotational energy typically comes from an engine or
electric motor. The fluid enters the pump
impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing),from which it exits.

 

Applications:
Widely used in hybrid bus, hybrid
passenger car, electric vehicles, trains,
ships and other heating and
cooling circulation system.

 

Structural features :
1: Major structure :Pump head, brushless DC motor
and controller

2: Features : Compact structure, strong sealing, strong
adaptability to the environment and media, structure and
material are corrosion resistance, high impact resistance,

with good heat dissipation structure.

1,Water pump head structural features
Pump head:

1: Volute chamber and impeller made by High-performance plastic material(Compression resistance, high
strength, corrosion resistance) ;

2: Features of low specific revolution
impeller chamber and impeller structure:The restriction of fluid flow is enhanced
and the diversion effect is good,small hydraulic loss; the water resistance friction is low, the fluid fluctuation is small


3 :The structural characteristics of high-lift pump volute chamber: improve the shape of the runner channel,volute tongue Angle
and volute profile; It can well-reduce the eddy current loss, impact loss and wake jet flow under high pressure.


Water pump head structural features
1: Long life, high durability;
2: High hydraulic efficiency(Rated condition ≥64%);
3: Good stability and low noise

4: Flat washers:
The wear resistance of ceramic bearing is improved by using hard alloy material with high wear resistance, so it will improve the stability and durability.

2:Brushless Motor structure features
Motor structure :

1:The rotor stainless steel housing is
sealed by laser welded
a)The new stainless steel material is
more resistant to corrosion ;
b)Much better leakproofness ;

2: The stator winding :
1, Reduce resistance, reduce
heat loss ;2, Reduce the
number of windings; Reduce
the volume of space.
c) Reduce the magnetic gap , reduce
magnetic flux loss ;


BLDC motor structural features
1, Tight seal, high corrosion resistance, strong
medium adaptability;
2, Low calorific value, low current and high motor
efficiency;
