Multi-roots water ring vacuum pump vacuum unit

1. JZJ2B series Roots water ring vacuum unit overview:

JZJ2B series Roots water ring vacuum unit is based on Roots pump as the main pump, with water ring pump as the front pump in series. Roots water ring vacuum unit uses water ring pump as the front pump is more advantageous than other vacuum pumps. It overcomes the ultimate pressure difference when using a single water ring pump (the ultimate pressure of the unit is greatly improved than that of the water ring pump), and the disadvantage of low pumping rate under certain pressure, while retaining the advantages of Roots pump that can work quickly and have a larger pumping rate. In particular, it can be adapted to pump out a large amount of condensable steam, especially when the gas ballast oil seal mechanical vacuum pump has insufficient ability to remove condensable steam, or the solvent used can deteriorate the pump oil and affect the performance, or the vacuum system does not allow oil pollution. When equipped with explosion-proof motor and electrical appliances and comply with the appropriate safety rules, but also to remove flammable and explosive gases.

2. JZJ2B series Roots water ring vacuum unit USES:

JZJS series Roots water ring vacuum units are widely used in vacuum distillation, vacuum evaporation and dehydration crystallization in the chemical industry. Freeze-drying in the food industry; Vacuum drying in the pharmaceutical industry; Polyester chips in the light textile industry; High-altitude simulation test and other vacuum pumping systems.

3. JZJ2B series Roots water ring vacuum unit features:

1. Compared with single pump, Roots water ring unit has remarkable energy saving effect;

2, small footprint, reliable work;

3. Large pumping rate under high vacuum condition;

4, suitable for pumping in addition to air or other insoluble in water, does not contain solid particles, non-corrosive gas.

JZJ2B series Roots water (liquid) ring vacuum unit technical indicators:

Note: 1. The above table is a series of recommended standards. Due to different working conditions in actual production and application, many changes will occur in inhaled gas and pressure. Therefore, the selection should be checked and calculated according to the actual pumping process, gas release process, condensation of condensable gas, time change of inhaled pressure, etc. or the selection should be made according to the usage of existing equipment.

2. For the technical indexes of single pump, please refer to the parameter table of each pump.

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

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