Sumbersible pump why cannot idling?

Shandong Hairui Zhonglian Pump Industry Co. , ltd. The sumbersible pump that is a major produces manufacturer. When type selecting of client sumbersible pump, manufacturer of my company water pump can provide the before-sales service such as price of sumbersible pump model, sumbersible pump, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is about sumbersible pump why cannot the knowledge of the idling:

Sumbersible pump cannot the reason of the idling: Method of refrigeration of general sumbersible pump is water-cooled. It is no matter inside water refrigeration, outside water-cooling is method of refrigeration of double water of exterior and interior however, the refrigeration that demand water finishs sumbersible pump as medium comes loose hot exercise. When sumbersible pump idling, will be opposite without waterSumbersible pumpthe calorific place such as winding, bearing undertakes cooling, because this does not allow sumbersible pump idling.
Inside sumbersible pump, outside cooling action has compared the cooling method of double water-cooling, sumbersible pump lumen fills water, core of stator core, stator winding, rotor and rotor winding (rotor guides carry ring with rotor) etc all dip is in water, cool by the water inside machine directly. The quantity of heat that the partial resistor loss of the loss of electromotor stator iron, resistor loss of winding of stator chamfer ministry and upright ministry winding produces passes stator core directly, classics housing passes the cooling water that sheds classics housing appearance to take away. The resistor loss of rotor winding and the quantity of heat that rotor iron loss produces, air gap of one part classics passes stator directly, the cooling water outside passing electromotor via stator is taken away; In the water that another part sends rotor pitch, the quantity of heat that loss quantity of heat and mechanical loss place produce this part quantity of heat and the another part resistor that stator carries ministry winding to pass lumen to fill water together, classics lumen fills water to pass stator core, housing and bearing, relatively also pass electromotor housing and bearing eventually the appearance that waits for component passes cooling water to take away.
The pump head that the reason of the idling still has even if cannot dive electric machinery place is taken divides sumbersible pump, a lot of plain bearing liner are water smooth, if the idling falls in the circumstance that does not have water, happen between pump shaft and plain bearing liner dry grind, electric machinery is very simple overload is calorific, burn down electric machinery.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is about sumbersible pump why cannot the introduction of the idling, still think to this problem like you deep one pace understanding, or the problem that has price of model of type selecting of product of other pump industry, water pump, water pump, water pump needs to solve, contact this water pump manufacturer please, my company still produces the pump below fluid, welcome you at any time seek advice.
