1. Overview of JZJ2B series Roots water ring vacuum unit:

  The JZJ2B series Roots water ring vacuum unit is based on the Roots pump as the main pump and the water ring pump as the front stage pump in series. It is more advantageous for the Roots water ring vacuum unit to use the water ring pump as the foreline pump than the other vacuum pumps. It overcomes the limit pressure difference when the single water ring pump is used (the ultimate pressure of the unit is greatly improved compared to the water ring pump). The disadvantage of low pumping rate under a certain pressure, while retaining the advantage that the Roots pump can work quickly and has a large pumping rate. In particular, it can be adapted to remove a large amount of condensable steam, especially when the gas-fired oil-sealed mechanical vacuum pump has insufficient ability to remove condensable steam, or the solvent used can deteriorate the pump oil and affect performance, or the vacuum system does not allow oil contamination. The time is more obvious. When equipped with explosion-proof motors and appliances, and comply with the appropriate safety rules, you can also remove flammable and explosive gases.

 

2.JZJ2B series Roots water ring vacuum unit use:

  JZJS series Roots water ring vacuum unit is widely used in vacuum distillation, vacuum evaporation, dehydration crystallization in the chemical industry; freeze drying in the food industry; vacuum drying in the pharmaceutical industry; polyester slicing in the textile industry; high-altitude simulation test, etc. Vacuum pumping system.

  Third, JZJ2B series Roots water ring vacuum unit features:

  1. The water-saving effect of the Roots water ring unit is significantly higher than that of the single pump;

  2. Small footprint and reliable work;

  3. Under high vacuum conditions, the pumping rate is large;

  4. It is suitable for removing air or other gases that are insoluble in water, free of solid particles and non-corrosive.

Note: 1. The above table is the recommended standard series. Due to the different working conditions in actual production applications, the inhalation gas and pressure will change a lot. Therefore, the selection process should be based on the actual pumping process, gas release process, and condensability. The gas condensation condition, the time change of the suction pressure, etc. are checked or compared with the existing equipment usage.

2. The technical specifications of the single pump are detailed in the pump parameter table.

3. The maximum suction pressure refers to the highest pressure that the main pump can start. If it is operated for a long time above this pressure, the main pump will be overloaded.

4. If the vacuum pump motor, electric contact vacuum gauge and electric control cabinet need to be explosion-proof, please indicate when ordering, the 2BV2 series in the above table should be changed to 2BV2-EX series, and the 2BV5 series should be changed to 2BV6 series.
