XBD series well use fire-fight submersible pump group

Use  conditions
Well use fire fight submersible pump group is a kind of water lifting machinery tool which the motor and pump directly connected as an integrated body. It is mainly for lifting water to the building fire fight, for transporting clear water and the liquid which the physical and chemical property similar to water, and the temperature below 20℃。

1. Demand for power source
(1) Rated frequency is 50Hz, rated voltage at motor end should be 380± 5% or 660± 5% three phase alternating current power supply(660V to be mentioned when user require).
(2) The loading power of the transformer should not exceed 75% of the capacity.
(3) When the transformer is much far away, should consider the cable voltage drop.
2. When the use condition special, manufacture can be performed as the user requirement.

Structure explanation

1、 The well use fire fight submersible pump group composed of five parts:pump, motor, transporting pipes, water-proof cables and control system, the pump is a kind of single suction, multiple stages, vertical and centrifugal pump.

2、 The chamber full of clear water,mainly for cooling the motor and the bearing lubrication.During operation,as the temperature changing may cause the water-filling volume to vary, a pressure regulator is equipped in the motor to allow the calibration.
3、 a sand-preventing sealing mechanism consisting of a sand thrower and a mechanical sealis mounted on the upside motor, composing a sand-preventing structure, the whole motor is well sealed by its sealing structure.
4、 The water injection hole and exhaust hole are opened at the upper part of the motor, and a drainage hole at the lower part.
