Steel industry centrifugal pump energy consumption
Analysis and centrifugal energy saving measures:
1 to optimize existing pump
by adjusting the pump speed and impeller diameter, will affect the flow of the pump head and shaft power, but has no effect on the efficiency curve, so that the pump can work in efficient zone. Adjusting the flow head above is a certain range of restrictions, if conditions changed so much, the original pump may be necessary to consider the modification.
2 to improve the efficiency of centrifugal pumps
The first step in the selection and comparing each vendor selection program, under the premise of considering cost-effective as possible use high-efficiency programs; the second step, certain accredited professionals Mill Producer of affect pump efficiency of key components such as impellers, pump, pump cover, deflector (vertical long axis of the pump) and other manufacturing quality producer, in particular wing of the impeller, the water angle, indexing blade runner shape, finish, such as quality control, so that products delivered are of high efficiency products in the current production conditions; the third step, the production site installation and commissioning process, to ensure that the basis of reliable pumps, the driving machine the good, before and after the valve switching flexibility, piping layout design is reasonable, feasible and safe on-site control, each operation monitoring instrumentation complete and accurate, to ensure that the process of operation of the pump can be monitored in real time; the fourth step, in the long run is to pay attention to the pump equipment point inspection, report abnormal situation immediately reflected in the normal small repair, overhaul cycle, the response of each check and replace wearing parts, ensure long-term efficient and safe operation of the pump.
Pump iron and steel industry is energy-hungry, a variety of pump is widely used in various processes in the steel industry, the water cycle, hydraulic, cooling, washing, water treatment and many other processes can all see the various models and specifications of the pump. Among the most widely used is the centrifugal pump, it may be because there are many different structural forms of structure, such as a single-stage single-suction centrifugal pumps, single-stage double-suction centrifugal pumps, multistage pumps, vertical long axis pumps, submersible pumps, etc. but their core components - the impeller are all centrifugal, so this article focuses on what the centrifugal pump energy consumption.
