Centrifugal pump energy-saving measures
The centrifugal pump is a pump that uses the impeller to generate the driving force. It is a vane pump. During the rotation process, the rotating impeller rotates the mechanical energy to the liquid due to the interaction of the blade and the liquid so that the pressure of the liquid can be increased. To achieve the purpose of transporting liquid, the action of the rotating impeller on the liquid transfers the mechanical energy of the prime mover to the liquid. What are the measures for energy saving and consumption reduction of centrifugal pumps?
1, improve the efficiency of centrifugal pumps
The first step is to compare the selection schemes of each supplier in the selection process and try to use the high-efficiency scheme on the premise of considering the cost performance;
In the second step, a certain number of professionals are stationed in the factory to supervise the manufacturing quality of key components such as impellers, pump bodies, pump covers, and deflectors (vertical long-axis pumps) that affect pump efficiency especially for impellers. As a result, the quality of the wing shape, water angle, blade index, runner shape, finish, etc., is controlled so that the delivered product is highly efficient under current production conditions.
The third step, in the installation and commissioning process of the production site, to ensure that the foundation of the pump is reliable, the alignment with the drive machine is good, the front and rear valve switches are flexible, the pipeline layout design is reasonable, the site control is safe and feasible, and the operation monitoring instruments are complete and accurate. The pump's operation process enables real-time monitoring.
The fourth step is to pay attention to the inspection of the equipment during the long-term operation of the pump and to report the abnormal situation immediately. In the normal minor repair and overhaul cycle, all the wearing parts should be inspected and replaced to ensure the pump's long-term high efficiency and safety. Running.
2. Optimize existing pumps
Adjusting the impeller diameter and the pump speed will affect the pump's flow head and shaft power but not affect the efficiency curve, allowing the pump to operate in the high-efficiency zone. However, the above adjustment of the flow head has a certain range of restrictions. If the working conditions change too much, the original pump may have to consider the modification.
