Deep well submersible pump cooling

Various structure of the deep well submersible pump cooling methods vary in the industry can be divided into four basic types. Xiaobian today for everyone to introduce
Deep well submersible pump cooling method (A): electric motor inside and outside the dual water cooling mode
Fill the cavity with water-filled submersible pump filled with water until the rotor core and rotor windings and other parts are immersed in water directly from the machine to cool the water. Motor parts within the resistance loss of heat generated directly through the stator core, the shell passed through the casing surface of well water away. The rotor winding resistance loss and rotor iron loss heat generated by the part of the stator to the motor through the well water away; the other part of the rotor cavity to the water, the cavity filled with water to the stator core, chassis and Bearing, and finally through the motor housing and bearing parts and other parts of the surface to the well water away. This motor inside and outside the dual water cooling cooling effect is better. Facts have proved that wells with water-filled submersible pump stator winding temperature rise is generally relatively low.
Deep well submersible pump cooling (2): stator housing water cold, direct water cooling rotor Fang Wu
The use of this cooling method of the main wells with submersible pump QJ deep well submersible pump. The motor stator is a separate sealed chamber, the stator core and winding are enclosed, and the rotor cavity filled with water. The heat generated by the resistance loss in the motor is directly transferred to the well water flowing through the shell surface through the stator iron core or the cavity filling material. The rotor winding resistance loss and rotor iron loss generated by heat, part of the air gap through the water and shield directly to the stator, the stator to the motor outside the well water away: the other part of the rotor cavity to the Filled with water, this part of the heat and mechanical loss of heat generated by the cavity filled with water to the stator core, housing and bearing seat, and finally through the motor housing and bearing parts and other parts of the surface specifically to the motor Outside the well water away.
