Submersible pump is characterized by built-in submersible pumps and exterior submersible pumps, then what different places do they have to make people distinguish it out.
Built-in submersible pump, which in the motor base outside another electric pump shell to surround it, the motor base and the pump shell can be made into one, into a ring structure, and then install the pump outlet cover. The liquid flows through the circular space between the submersible pump housing and the motor base, and then cools the surface of the motor base directly and flows out through the aqueduct. Built-in submersible pump motor cooling effect is better, suitable for large areas of the ground in the occasion, long-term use of good results, high reliability.
Outside submersible pump, installed in the motor outside the water pipe as a water flow, the liquid directly from the pump connected to the drainage pipe, not through the motor surface, its cooling than the built-in submersible pump to be worse.
In summary, the difference between built-in and exterior submersible pumps is also very large and can be easily identified. Due to the poor cooling performance of the exterior submersible pump, it needs to be improved and made it in a large area Drain, the motor exposed to the surface, the cooling effect becomes better.
