Circulation pump is a large energy consumer in the iron and steel industry. Pumps of various specifications are widely used in various processes in the steel industry. Various types of pumps can be found in various processes such as water circulation, hydraulic pressure, cooling, flushing, and water treatment. And specifications of the pump.
One of the most widely used is the circulation pump (centrifugal pump), which can have a variety of structural forms due to the different structures, but their core components - the impellers are all centrifugal, so this article focuses on the energy saving of the circulation pump Reduce consumption.
Analysis and Measures of Energy Saving and Consumption Reduction of Circulation Pumps:
1, improve the efficiency of the circulation pump
The first step is to compare the selection schemes of various suppliers at the time of type selection, and try to use high-efficiency solutions under the premise of considering cost performance. In the second step, stationing certain professional personnel in the factory supervisor will affect the efficiency of the circulation pump. The production of key components such as impellers, pump bodies, pump covers, flow deflectors (vertical long-axis pumps), etc. are supervised, especially for the wing shape, water discharge angle, blade indexing, runner shape, and finish of the impeller. The quality is controlled so that the delivered product is an efficient product under the current production conditions. In the third step, during the installation and commissioning of the production site, the foundation of the pump must be secured, and the centering of the pump is good. Valves are flexible in switching, rational in piping layout design, safe and feasible on-site control, and complete and accurate in operation monitoring instruments to ensure real-time monitoring of the pump's operation process. The fourth step is to pay attention to the equipment during the long-term operation of the circulating pump. , Found that the abnormal situation immediately report the report, in the normal minor repair, overhaul cycle, the inspection and replacement of the vulnerable parts to ensure the long-term efficient and safe operation of the circulating pump.
2, optimize the existing pump
By adjusting the diameter of the impeller and the speed of the pump, the flow head and shaft power of the pump will be affected, but there will be no effect on the efficiency curve, so that the pump can operate in the high efficiency zone. The above adjustment of the flow head is limited to a certain extent. If the operating conditions change too much, the original pump may have to be modified.
High Temperature Caster Wheels are made out of phenol formaldehyde resin,this series of casters could work in 280℃ or 220℃ environments.
Base on materail feature, High Temperature Casters could be wide range, like ceramic factory, hosiptal autoclaves, bakeries oven, food factory...etc.
According to differnent environments, there are stainless and steel bracket, medium duty and heavy duty, black color and brown color for choosing.
