Water Ring Vacuum Pump for Power Plant
Vacuum pumps mainly include centrifugal vacuum pumps and water ring vacuum pumps. Their working principles are similar, but their realization methods are different.
Water ring vacuum pump is widely used because of its advantages of safe use, simple operation, economical operation, reliable operation, small contact area between static and dynamic parts, no need for oil lubrication, low operating noise and compact structure.
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 pipeline, gas source and power supply, and can save a lot of water resources.
Water ring vacuum pump can be divided into axial suction and radial suction and exhaust.
The advantages of axial suction and exhaust are simple structure and convenient maintenance, while the disadvantages are large hydraulic loss and low pump efficiency.
The advantages of radial suction and exhaust are small hydraulic loss and high pump efficiency, while the disadvantages of radial suction and exhaust are complex structure of gas distributor and high precision of processing and installation.
The foreign manufacturers of vacuum pump complete sets mainly include Nash Company of the United States and Siemens Company of Germany. Expanding Vacuum Pump Factory Co., Ltd. is one of the domestic manufacturers. We have introduced all the technology of Siemens Company of Germany to design and manufacture.
To produce matching equipment for domestic turbogenerator units.
Operation practice shows that domestic equipment can replace imported equipment, and domestic equipment has more price advantages than imported equipment.
It is precisely because of the superiority of performance and price that water-ring vacuum pump system is widely used not only in 300,600 MW units but also in many medium and small units of high and ultra-high pressure in recent years, in order to replace the original water-jet pumping system, bringing long-term benefits to power plants.
