Description of water ring vacuum pump in power plant
Vacuum pump mainly includes centrifugal vacuum pump and water ring vacuum pump and other types, their working principle is similar, but different implementation. Water ring vacuum pump is widely used due to its advantages of safe use, simple operation, economical operation, reliable operation, small contact area of static and static parts, no need for oil lubrication, low operating noise and compact structure. The vacuum pump pumping system has the advantages of simple pipeline layout, small floor area and minimal civil engineering construction. It can be put into commercial operation only by connecting pipelines, air sources and power sources, and it can save a lot of water resources.
Water ring vacuum pump has axial suction and exhaust and radial suction and exhaust. The advantages of axial suction and exhaust are simple structure and convenient maintenance. Disadvantages are large hydraulic loss, pump efficiency reduced. The advantages of radial suction and exhaust are small hydraulic loss and improved pump efficiency. The disadvantage is that the gas distributor structure is complex, machining and installation accuracy is higher. The foreign manufacturers of complete vacuum pump equipment mainly include Nash company of America and Siemens company of Germany. Shanghai feilu vacuum pump factory co., LTD is one of the domestic manufacturers. For the production of domestic turbine generator sets supporting equipment. Operation practice shows that domestic equipment can replace imported equipment, and domestic equipment has more price advantage compared with imported equipment. Due to its advantages in performance and price, the water-ring vacuum pump system is widely used not only in units of 300 MW, 600 MW and above, but also in many small and medium-sized units of high pressure and ultra-high pressure in recent years, which replaces the original water-jet pumping system and brings long-term benefits to the power plant.
