Product Details
Product Introduction
The JZJ2B (S) series Roots liquid ring vacuum unit is composed of a ZJP Roots pump as the main pumping unit and a 2BV (2SK) liquid ring vacuum pump or Roots liquid ring vacuum unit as the front stage pump. It can not only be used to remove general gases, but also to extract gases containing moisture and a small amount of dust. Compared with general mechanical vacuum pumps, it has the advantages of not being afraid of oil pollution, water vapor, and dust; Compared with general liquid ring vacuum pumps, it has the advantages of high ultimate vacuum degree and high pumping speed under higher vacuum degree conditions. It is an ideal vacuum pumping equipment for drying, dehydration, and vacuum degassing in industries such as textiles, food, chemicals, and pharmaceuticals.
Main Features
1. The JZJ2B series Roots liquid ring vacuum unit adopts an efficient and energy-saving 2BV type liquid ring vacuum pump as the front stage pump. Therefore, the JZJ2B series Roots liquid ring vacuum unit has the advantages of high efficiency, compact structure, no leakage (2BV series is designed as a mechanical seal standard, different from 2SK series packing seal), corrosion resistance (2BV series uses stainless steel impeller), and high grade compared to the JZJ2S series Roots liquid ring vacuum unit.
2. The working fluid of the front stage pump of the Roots water ring vacuum unit is mostly water, and organic solvents (such as methanol, ethanol, dimethyl ether, etc.) or other liquids can also be used. Using the front stage pump as a closed-loop circulation system greatly reduces environmental pollution and greatly improves the recovery of organic solvents. The ultimate vacuum degree is determined by the saturated vapor pressure of the working fluid.
Main technical indicators
Flow rate: 30-2500L/S (1.8-150m ³/min)
Ultimate vacuum degree (above -100kPa):
Secondary Roots water ring vacuum unit (Roots pump+water ring pump): 267Pa
Three stage Roots water ring vacuum unit (Roots pump+Roots pump+water ring pump): 25Pa
Four stage Roots water ring vacuum unit (Roots pump+Roots pump+Roots pump+water ring pump): 0.5Pa
