Sewage submersible pump composition of the main material is cast iron, which is driven by electric, sewage submersible pump works and the submersible pump works similar sewage submersible pump is the main purpose of sewage treatment. It is mainly used in engineering, industry, hospitals, construction, hotels and other industries, mainly to achieve the delivery of solid and long fibers with sludge, waste water, urban sewage which also includes corrosive and aggressive media. As its range of use increases, understanding of the performance parameters of sewage submersible pumps is becoming more and more important. Sewage submersible pump performance parameters The following describes the commonly used several types of sewage submersible pumps: 1, Model: 25QW8-22-1.1: Diameter (mm): 25; flow rate (m3 / h): 8; head (m) 22; Power (kw): 1.1; Speed ​​(r / min): 2825; Efficiency (%): 38.5; 2. Model: 32QW12-15-1.1: Diameter (mm): 32; ; Head (m): 15; Power (kw): 1.1; Speed ​​(r / min): 2825; Efficiency (%): 40; 3, Model: 40QW15-15-1.5: Diameter (mm): 40; m3 / h): 15; Head (m): 15; Power (kw): 1.5; Speed ​​(r / min): 2840; Efficiency: 45.1; 4, Model: 40QW15-30-2.2: ): 40; Flow rate (m3 / h): 15; Head (m): 15; Power (kw): 1.5; Speed ​​(r / min): 2840; Efficiency (%): 48; 5. Model: 50QW20-7 -0.75: Diameter (mm): 40; Flow rate (m3 / h): 15; Head (m): 30; Power (kw): 2.2; Speed ​​(r / min): 2840; Efficiency: 54; Above 5 types of sewage submersible pump analysis, I It can be understood more types of submersible pump section, when approximately the same performance parameters. The main difference is the difference between the specific values. In practice, precisely because of these differences, in the normal production work, users have more choices, but also according to the actual situation to choose the most suitable production of the necessary products.
