Roots water ring vacuum pump unit uses: JZJ2B (S) series Roots - liquid ring vacuum pump unit is made by the ZJ Roots pump as the main pump, 2BV (2SK) type liquid ring vacuum pump or Roots - liquid ring Vacuum pump unit as the former pump composed of suction unit. It can not only be used to remove the general gas, but also can suck the water containing a small amount of dust and gas. Compared with the general mechanical vacuum pump, it has the advantages of not being afraid of oil pollution and being afraid of moisture and dust. Compared with the general liquid-ring vacuum pump, it has the advantages of high ultimate vacuum and large pumping speed under higher vacuum conditions. It is an ideal vacuum extraction equipment for drying, dehydration and vacuum degassing in textile, foodstuff, chemical and pharmaceutical industries. Second, Roots water ring vacuum pump unit features 1.JZJ2B series Roots liquid ring vacuum pump unit uses a high efficiency and energy saving 2BV type liquid ring vacuum pump as a front-stage pump, so JZJ2B series Roots liquid ring vacuum pump unit than the JZJ2S series Roots solution Ring vacuum pump unit with high efficiency, compact structure, no leakage (2BV series mechanical seal standard design, unlike the 2SK series of packing seal), corrosion resistance (2BV series aluminum bronze impeller), the advantages of high protection grade. 2. Roots water ring vacuum pump unit working fluid pump more water, but also can be used organic solvents (available methanol, ethanol, xylene, acetone and other organic solvents) or other liquids, the foreline pump as a closed loop system Use, greatly reducing the pollution of the environment, while greatly improving the recovery of organic solvents. The ultimate vacuum is determined by the saturated vapor pressure of the working fluid.
