JZJ2B (S) series Roots - liquid ring vacuum unit is composed of ZJP Roots pump as the main pump, 2BV (2SK) liquid ring vacuum pump or Roots - liquid ring vacuum unit as the front stage pump. It can be used not only to extract ordinary gases, but also to extract gases containing water and a small amount of dust. Compared with the general mechanical vacuum pump, it is not afraid of oil pollution, water vapor and dust, etc. Compared with the general liquid ring vacuum pump, it has the advantages of high ultimate vacuum degree and high pumping speed under higher vacuum degree. It is an ideal vacuum pumping equipment for drying, dewatering and vacuum degassing in light textile, food, chemical and pharmaceutical industries.
The main features
1, JZJ2B roots series liquid ring vacuum unit adopts the high efficiency and energy saving type 2 bv liquid ring vacuum pump as the backing pump, so JZJ2B roots series liquid ring vacuum unit roots than JZJ2S series liquid ring vacuum unit with high efficiency, compact structure, no leakage (2 bv series of mechanical seal standard design, different from the 2 sk series packing seal), corrosion resistant (2 bv series stainless steel impeller), the advantage of high grade.
2, roots water ring vacuum unit of working liquid pump before use water more, also can use organic solvent (methanol, ethanol, xylene, acetone and other organic solvents), or other liquid, the backing pump used as closed-circuit circulation system, greatly reduce the pollution to the environment, at the same time, greatly improving the recycling of organic solvents. The ultimate vacuum is determined by the saturated vapor pressure of the working liquid.
