JZJ2B/JZJ2S series Roots water ring vacuum unit is composed of ZJ or ZJB Roots vacuum pump as the main pump and 2BV or 2SK water ring vacuum pump or Roots water ring unit as the fore pump, It not only can suction the general gases, but also can suction the other gases that contain moisture or a small quantity of dust. Compared with the general mechanical vacuum pump, it is not easy to be polluted by oil, moisture and dust. And compared with general water ring vacuum pump, it has higher vacuum and bigger pumping speed when it works in the high vacuum.
The unit is used extensively in many areas such as chemical, electric, machinery, pharmacy, upper air simulation test, food sublimation drying etc.
When the oil is used as the working liquid of the fore pump, it can effectively increase the vacuum of Roots vacuum unit (refer to parameter list), Roots oil ring unit is closed circulation system, it can reduce the pollution and save water. It is widely used in the vacuum dipping, vacuum drying, and vacuum pumping.
How to choose the Roots water ring vacuum pump unit: Generally ,to choose the water ring pump as the fore pump is more favorable than others, because it can pumping vast condensable steam ,especially when use the gas ballast and oil seal mechanical vacuum pump is not able to eliminate condensable steam, or the suction solvents can deteriorate pump oil then effect its performance ,or sometimes the system is not allowed the pollution .When choosing the vacuum unit, it is necessary to make the ultimate vacuum half or more than one of the working vacuum in order to meet the requirements.
Roots water ring unit generally have the following types:
★ Roots pump +water ring pump: The function of the water ring vacuum pump is to form the pre-vacuum for the Roots pump. At present, 2BV.2BE1, 2SK series water ring vacuum pumps usually are used as the fore pump, they can increase the ultimate vacuum of the unit. Actually don’t use SK series water ring vacuum pump with low vacuum.
★ Roots pump+Roots pump+water ring pump: When use one set of Roots vacuum pump, especially combining with water ring vacuum pump, the entire unit maybe have the lower vacuum with the restricted range, but if two sets of Roots pumps combine with water ring pump again can increase the entire vacuum greatly .
★Roots pump+Roots pump+Roots pump+water ring pump:If the two Roots pumps and water ring pump still can’t meet the requirement of the vacuum, another Roots pump can be added, these series Roots pump units are used insome high vacuum technology of vacuum freezing or drying
