I.Applications of JZJ2B Roots Water Ring Vacuum Unit:

JZJ2B Roots Water Ring Vacuum Unit is a gas pumping unit composed of ZJP Roots vacuum pump as the main pump, and2BV water ring vacuum pump orRoots water ring vacuum unit as the backing pump. It can not only be used to extract general gases, but also can pump gases containing moisture and a small amount of dust. Compared with general mechanical vacuum pumps, it has the advantages of being not afraid of oil pollution, moisture and dust; compared with general water ring vacuum pumps, it has the advantages of high ultimate vacuum and large pumping speed under higher vacuum conditions. It is an ideal vacuum pumping equipment for drying, dehydration and vacuum degassing in industries such as textile, food, chemical, pharmaceutical, etc., and it is also the most widely used vacuum unit in various industries.

II. Features of JZJ2B Roots Water Ring Vacuum Unit:

1. The JZJ2B Roots water ring vacuum unit adopts the high-efficiency and energy-saving2BV water ring vacuum pump as the backing pump, so theJZJ2B Roots water ring vacuum unit has the advantages of high efficiency, compact structure, no leakage (the2BV water ring vacuum pump is designed with mechanical seal standard, different from the2SK water ring vacuum pump with packing seal), corrosion resistance (2BV series adopts 304 stainless steel impeller), and high protection level compared with theJZJ2S Roots water ring vacuum unit. However, the 2SK water ring vacuum pump produced by our company can also adoptmechanical seal, which can be divided into built-in type and external type.

2. The working liquid of the backing pump of the JZJ2B Roots water ring vacuum unit is mostly water, but organic solvents (such as methanol, ethanol, xylene, acetone, etc.) or other liquids can also be used. When the backing pump is used as a closed-loop circulation system, it greatly reduces environmental pollution and greatly improves the recovery of organic solvents. Its ultimate vacuum is determined by the saturated vapor pressure of the working liquid.

III. Model designation method of JZJ2B Roots Water Ring Vacuum Unit:

JZJ2B600-2.2

J-----Vacuum unit

ZJ-----Main pump is Roots vacuum pump

2B-----Main pump is 2BV water ring vacuum pump

600-----Pumping speed of main pump (L/S)

2.2-----Pumping speed ratio of main pump to backing pump
