Structural characteristics and working principle:
QJ submersible electric pump is a high-efficiency and energy-saving water-lifting tool that combines a pump and a pump to work in the water. It consists of a submersible motor, a pump, and a riser. The interior is filled with clean water. For cooling motors and lubricating bearings. / 多级离心闭式叶轮，导流壳输送液体。 The motor winding is made of polyethylene insulated nylon sheathed water-resistant electromagnetic wire. The upper part of the motor is sealed with a sand sling ring and a skeleton oil seal to prevent leakage of the medium inside and outside the motor . The shell conveys liquid.
