High Efficiency Energy-Saving Hbe Liquid Ring Vacuum Pump
HBE liquid-ring vacuum pump is an energy-saving product developed by our company, and is used to pump gas which carries no solids undissolved or just slightly dissolved in working liquid, to form vacuum and pressure in the closed container.
Working Principle
The impeller is assembled eccentrically inside the casing. When the impeller revolves as the indicated direction in above figure, the liquid is thrown outwards under centrifugal force to form a liquid ring rotating concentrically with the casing. As a result, a crescent pocket area is developed between hub and the inner surface of the liquid ring. As rotaion proceeds from point A to point B, the pockets area between adjacent wanes becomes progressively larger, i.e vacuum is set up and gas is drawn in via the suction port. And as rotation proceeds from point C to point A, the pocket becomes smaller and smaller, the gas is compressed to be as much as outside pressure, then it is finally ejected out though discharge port.
The order related tests, confirm the performance of pump conform.
The company carries out the tests below as standard:
Hydrostatic pressure test:
Hydrostatic pressure test based on clean water at ambient temperature,test pressure is 1.5 times on design pressure.
Performance test:
Measurement according to ISO9906,accuracy class∥,acceptance class2B.
NPSH test:
According to ISO5199 standard.
Vibration test:
According to ISO5199,vibration lightness level is controlled at class A.
Temperature test:
Test the temperature rise of bearing,and keep records.
Raw material inspect:
Spare and casting parts inspection,to ensure the reliability of the whole machinery.
