Analysis and measure of energy saving and consumption reduction of centrifugal pump
1. To improve the efficiency of the centrifugal pump
The first step in the selection of multiple selection scheme and evaluate suppliers, in considering the price under the premise of selecting high efficiency scheme; the second step, some professional personnel in the factory in key parts of the producer, such as the influence the efficiency of the pump impeller, pump body, pump cover, deflector (vertical long shaft pump manufacturing quality) the producer, especially on the impeller outlet angle, wing shape, leaf shape, flow dividing, finish quality control, so that the delivery of the product in the current production conditions of high efficiency products; the third step in the process of installation and debugging of the production site, to ensure the reliable basis of pump the driver, and on the good, and the valve switch flexible, piping layout design is reasonable, the field control is safe and feasible, the monitoring instrument complete and accurate, ensure the operation process of pump can perform real-time monitoring; the fourth step is in Pump running over a long period of time to pay attention to the inspection of the equipment, found abnormal immediately reflect reporting. In normal minor repairs, overhaul period, deal with the wearing parts to replace the inspection, to ensure the pump's efficient and safe operation.
2. Optimize the existing pump
By adjusting the diameter of the impeller and pump speed, pump flow head and shaft power will be affected, but the efficiency curve has no effect, so that the pump can work in the high efficiency area. The above adjustment flow - lift is a certain limits, if conditions change too much, the original pump may will be considered a modification.
