Liquid ring type vacuum pump (BW Series :BW7K2,BW8K2,BW10K2,BW12K2)
In a cylindrical housing, partially filled with sealing liquid, a multi-blade impeller on a shaft is positioned eccentrically. Port plates with inlet and discharge openings are positioned on either side of the impeller.A liquid ring is created by the centrifugal force generated by the rotating impeller. This force holds the liquid ring against the inner wall of the pumping chamber. Since the impeller is located eccentric to the pumping chamber, the depth of entry of the blades into the liquid ring decreases and increases as the impeller rotates. This creates increasing impeller cell volume on the inlet port side, creating a volume. On the discharge port side, the impeller cell volume decreases, as the blades move further into the liquid ring, increasing the pressure, until discharge takes place through the discharge port. A continuous flow of fresh sealing liquid is supplied to the pump via the sealing liquid inlet.
1) If you use water or oil as a fluid rod it is suitable for exhaust gas containing water vapor or moisture.
2) fasting delivers high performance at a low pressure of less than 200Torr (3 × 104Pa).
3) suitable for exhaust of flammable or corrosive gas .
4) You can apply a variety of motors .
5) The friction of the exhaust gas is used a lot of parts of corrosion-resistant materia
6) the friction part is only liquids So wear a little less trouble
7) It is possible to operate at high temperatures.
8) You can adjust the temperature control.
