1、 Introduction

The QSZ axial flow submersible electric pump and QSH mixed flow submersible electric pump developed and researched by Galaxy Company are mainly developed and designed based on the characteristics of China's numerous rivers, severe flood control and drainage situations, and the occurrence of drought conditions at any time. This model is mainly used in plain areas, with a lift of 2.5-15m, a flow rate of 450-3000m ³/h, and a drainage and irrigation area of about 1000-3000 acres for small and medium-sized electromechanical drainage and irrigation stations. It is more suitable for temporary flood control, drainage, and irrigation in areas without pumping stations, and can also be used for large-scale fountain water features, water curtain water supply, amusement park surfing water sources, and other purposes of circulating water. The feature of this machine is that the water pump and motor are integrated, and it can work underwater at the same time. It can be operated remotely or automatically controlled, and there is no need to build a pump room (pumping station) or ground building facilities, thus greatly saving station construction investment. The machine also has the advantages of simple structure, easy installation, use, and maintenance, safe and reliable operation, and high efficiency of pump station equipment.
