What is installed submersible pumps
External-mounted submersible pump sucking liquid shield through the impeller submersible pumps directly from pressurized water egress and structural design is simple, relatively efficient, typically outside the installed submersible pumps. The cooling conditions in order to improve the installed submersible pumps, submersible pumps Motors Power Shell Jacket, liquid in the pump outlet high pressure inductive motor jacket cooling.
What is a built-in submersible pump
Built-in pump suction transmission fluid, after impeller pressure flow, usually cooling room, and surrounded by the loop current of the motor road, the liquid cooling outflow after the motor pump outlet, the whole pump efficiency drops slightly, but greatly increased the reliability of the pump, as the typical built-in submersible pump. Semi built-in submersible pump structure features exterior-mounted, built-in submersible pump
Between the pump outlet pipe through the motor housing are usually part of integrated with housing, to play a role in the cooling of the motor such as low water submersible pumps. Tubular is external to the pump submersible pump electric motors, pump impeller installed inside the motor, the two become one flesh, like conveying water within the rotor wall rotor motors for water-filled
For example, water-filled submersible pumps, large outer diameter, height, good cooling conditions.
