Analysis and Measures of Saving Energy and Reducing Consumption of Centrifugal Pumps

1 to improve the efficiency of centrifugal pumps The first step in the selection of more than the selection of suppliers of the program, in considering the premise of cost-effective as far as possible the selection of efficient programs; the second step, stationed in a certain number of factory staff producer, right The key components that affect the efficiency of the pump, such as the impeller, pump body, pump cover, deflector (vertical long axis pump) and other manufacturing quality monitoring, in particular, the impeller wing, outlet, blade indexing, The shape, finish and other quality control, so that the delivery of the product under the current production conditions of high efficiency products; The third step in the production site installation and commissioning process, to ensure that the solid foundation of the pump, and the driver In the good, before and after the valve switch flexible, reasonable pipeline layout design, site control safe and feasible, all running monitoring instruments complete and accurate, to ensure the pump running process can be real-time monitoring; The fourth step is the long-term operation of the pump should pay attention to the equipment Inspection, and found that anomalies immediately report, in the normal minor repair, overhaul cycle, should check the replacement of each wearing parts to ensure long-term efficient and safe pump operation. 2 Optimizing Existing Pumps By adjusting the impeller diameter and pump speed, the pump head and shaft power flow will be affected, but with no effect on the efficiency curve, allowing the pump to operate in a high-efficiency zone. The above adjustment flow head is a certain range of limits, if the conditions change too much, the original pump may have to consider modified.
