Liquid drive chamber.
At least one drive chamber is equipped with cooling liquid driving wheel in the preceding coolant liquid drive chamber and postcooling liquid drive chamber,
Cooling liquid driving wheel is fixed in shaft and interlocks therewith.
The present invention can also improve further below.
The cooling passage helically shape.
The cooling liquid driving wheel, which is coordinated or is interference fitted by keyway, to be fixed in shaft.
The cooling liquid driving wheel thickness is in 1-100mm.
The prepass hole and rear access opening, which are respectively separated, is located at casing both ends of the surface.
It is driven in the use of the present invention, only one coolant liquid of processing need to be covered in traditional motor front end cover and motor rear end
Driving wheel operating room, and cooling liquid driving wheel is mounted in the shaft of rotor.The present invention is closed using full mechanical, structure
Reason, simple for process, reliability is high, can have winding stator core and rotor to be carried out at the same time cooling, using effect in motor
It is good.What the present invention used is not necessarily to external driving power from driving cooling structure, effectively solves motor body and driving pump voltage not
The problem of matching.And the present invention need to only safeguard cooling liquid driving wheel, be readily disassembled and replace in use.
