Water ring vacuum pump is a pump equipped with a fixed vane eccentric rotor, you can throw liquid such as water to the stator wall, when the liquid and the stator to form a liquid ring, liquid ring and rotor blades together constitute A Variable Volume Rotary Variable Volume Vacuum Pump. With the thriving industrial development in China, water ring vacuum pump is also more and more types, the choice of products is the place to pay attention to more. Water ring vacuum pump Next, the main introduction in the product selection need to pay attention to the place: 1, SK, 2SK and SZ-type water ring vacuum pump in addition to the general gas can also be sucked, but also to pump flammable and corrosive gas. 2,2YK type liquid ring vacuum pump is characterized by high vacuum, strong applicability, 3, long-term operation in the 1.3 × 104--1 × 105 Pa (100--760 Torr) range, the selection of single-stage SK-type water ring Vacuum pump; long-term operation in the range of 5 × 103--1.3 × 104Pa (40--100Torr), the selection of two-stage 2YK water ring vacuum pump; long-term operation in the range of 1 × 103-1.3 × 104Pa (8--40Torr) 2YK double-stage oil ring vacuum pump. 4, water at room temperature to ≤ 15 ℃ for the best, generally not higher than 40 ℃, transformer oil or other low viscosity saturated oil vapor pressure industrial oil, the maximum temperature of 60 ℃, such as vacuum drying in the electrical industry. 5, In addition to water at room temperature, the choice of other working medium should be configured gas-liquid separator, cooler, etc., pump shaft seal should be sealed. Each product has its own unique place, even if it belongs to the same type of product. This is sometimes a very difficult issue for consumers, how to really choose to suit their own products, there are many lessons to be done. First of all, to understand the characteristics of the product is a good way, followed by the price, but the most important is the product selection needs attention. Because to understand these issues in advance for the commencement of the work can provide a more favorable protection. Related articles: Cryogenic pump selection Sputtering ion pump selection
