China 2be1s Series Double-Stage Water Ring Vacuum Pump

Introduction
2BE1S series water ring vacuum pump is designed 2BE1 series based on the expansion of the two-stage water ring vacuum pump single action. 2BE1 series vacuum pump ultimate pressure of 3300Pa, ideal for working pressure range 20Kpa-100Kpa, when the inlet pressure is below 20Kpa, the rapid decay of the exhaust volume, then use a single-stage water ring vacuum pump efficiency is very low. 2BE1S series water ring vacuum pump design stage compression process, steady pumping speed in the high vacuum range, or to maintain a high degree of vacuum in a wide range of pumping rate. Working conditions at higher efficiency than single vacuum stage water ring pumps improve 35-40%, energy consumption is also reduced
Working
2BE1S two-stage water ring vacuum pump suction and discharge works with single-stage water ring vacuum pump 2BE1 same. When the impeller for rotation, the inner wall of the impeller chamber is formed eccentrically with water ring, water fills the gaps between the blades, with the rotation of the impeller, between the blade periodically constant reciprocating motion of the middle blade to change the size of the volume, at a fixed corresponding intake port and exhaust port with the complete suction, compression and discharge processes. And the role of the two-stage compression is discharged through the first stage by the second stage gas intake port, and then, after further compression of the second stage is discharged, the second
