Pump head is lower than the case 80WQ45-30-7.5 pump design point lift use, a situation in practice is often encountered in the selection of the pump when the pump, the pump head selected too high, while the actual use of the pump is used to reduce head; the other is that in use of the pump operating point is determined not so good, in other words the pump flow require frequent adjustment; there is a situation that requires frequent change of venue pump 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 will not only rise, but will decline, That is the power curve is a hump in the curve, and if so, we simply choose the rated power of the power a little over the hump point value, then the zero flow to the entire range of maximum flow 80WQ65-25-7.5 pump, you Whether on an operating point that is running, the pump will not exceed the power of the motor power. Submersible sewage pump applications submersible sewage pump is a pump and motor Siamese, and also work under submersible pumps into the liquid product, compared with the normal horizontal or vertical pump sewage pumps, submersible sewage pump obviously has the following Advantages aspects: 1. knot coaxial 80WQ46-22-7.5 pump and motor, the short axis, the rotating member and light weight, so the relatively small bearing on the loads (radial), much longer than the average life of the pump. 4. The absence of cavitation damage and irrigation water and other issues. Especially after a little to manipulate the staff brought great convenience. 5. vibration noise, motor temperature low environmental pollution.
