The composition and types of submersible pump are

A, submersible pump

Complete sets of equipment including: submersible pump submersible pump, submersible motor, control cabinet, electric cable, transformer and power supply line. Submersible pump device host for submersible pumps and submersible motor. Control cabinet for the operation, control and protection of electric submersible pump use. Power supply for the submersible motor transformer. Electric energy from the power line transformer is transported to a control cabinet; then the power cable from the transmission to the motor control cabinet. Therefore, the cable and the electric pump, must also be down to the well into the water.

Category two, submersible pump

The more types of submersible pump, but the pump parts are substantially the same, centrifugal pumps and submersible motor; supporting different types. Electric submersible pump in two categories: dry and wet submersible motor.

1, submersible motor

Dry type submersible motor with the common motor, motor for dry, full of air. The stator winding insulation structure and general motors and the same, but requires a certain degree of water resistance. The sealing structure of motor insulation life depends on the motor water.

2, wet submersible motor

The motor is filled inside the submersible pump with liquid, such as oil and water. Therefore, wet submersible motor and oil filling and the water filling type two.

The oil-filled submersible motors

Internal electrical submersible pump is filled with insulating oil for transformer oil. The stator windings and insulation structure has oil resistance, but also have certain water resistance. The sealing structure of motor insulation life depends on water.

The water filling type submersible motor

Internal electrical submersible pump filled with water. The stator windings and insulation structure with water-resistance absolute. Insulation life depends on the winding insulation materials and manufacturing processes.

Dry type submersible motor and oil-filled submersible motor, more complex structure, the sealing requirements high, therefore only applicable to small and medium-sized motor capacity. Low lift pump,

The drainage volume is relatively small.

General sewage pumps are submersible pump series, the company WQ type submersible sewage pump, JYWQ type jywq, AS type submersible sewage pump, ZW type self-priming sewage pump, belongs to the submersible pump series products.
