5. continuous operation for a long time. Submersible sewage pump due to the pump and motor coaxial, short shaft, rotating parts and light weight, it is relatively small bearing on the loads (radial), life is much longer than the average pump. Because of these advantages, submersible sewage pump more and more attention has been paid already. Increasingly wide range of uses, from a purely used to transport water to the present can transport all kinds of domestic sewage, industrial waste, construction sites and drainage, liquid feed and so on. Plays a very important role in municipal engineering, industry, hospitals, buildings, hotels, and other businesses in water conservancy construction. But everything is divided into two, for submersible sewage pump for the most critical issue is the reliability issue. Because the use of submersible sewage pump applications under liquid; medium transport are some of the mixed liquid containing solid materials; pump and motor are very close. Pump for vertical layout, rotating parts to withstand the weight of the water pressure in the same direction of the impeller. These problems are made submersible sewage pump seals, motor bearing capacity, bearing arrangement and selection and other requirements than the average sewage pump higher. Pump head is lower than the design conditions point lift use, a situation in practice is often encountered when the pump selection, pump head too high pump selection, but the actual use of the pump is lower lift used; Another is 65WQ37-13-3 pump, pump in use is not a good operating point is determined, in other words the pump flow require frequent adjustment; there is a situation pump needs often change locations use. These three cases were unfamiliar overload may affect the pump pump reliability. It can be said, for there is no full head pump features include submersible sewage pump, its use is limited to a large extent. The so-called full head feature, also known as non-overloading power characteristic curve refers to the flow rate increases with rise very slowly, it is desirable that when the flow reaches a certain value, the power not only will not rise again 150WQ180-20-18., but will decline, that the power curve is a hump in the curve, and if so, we simply choose the motor rated power value slightly over the hump power point 100WQ100-40-22, then at zero flow to maximum flow the whole range, whether you run on that operating point of a pump power will not exceed the motor power. 80WQ43-13-3 pump, pump, sewage pump provided by Anguo Shi Yuan Pumps Limited.
