ZJ, ZJL, ZJP Roots water ring vacuum unitWorking principle and structural characteristics

The JZJY type Roots vacuum pump liquid ring pump unit is composed of one or several Roots vacuum pumps connected in series with a two-stage liquid ring vacuum pump. The specific structure is shown in the figure below. The liquid ring pump is called the front stage pump, the Roots vacuum pump directly connected to the pumped system is called the main pump, and the Roots vacuum pump connected to the front stage pump and the main pump is called the intermediate pump (JZJY type two-stage unit does not have an intermediate pump).

Due to the fact that Roots vacuum pumps cannot be used alone, a front-end vacuum pump that meets the requirements for Roots vacuum pump use must be configured to form a complete unit type. The JZJY type Roots liquid ring pump vacuum unit, due to the use of a liquid ring vacuum pump as the front stage pump, is particularly suitable for suctioning gases with high humidity and industrial processes containing a large amount of water vapor and gases with certain corrosiveness and condensability. And because the liquid ring vacuum pump is suitable for long-term operation in the vacuum pressure range of atmospheric to several thousand pascals, the Roots liquid ring vacuum unit can be suitable for: vacuum distillation, vacuum evaporation, dehydration crystallization, and polymerization reactions of chemical products; The three major processes of polyester chip drying in the textile industry, drying of leather products, freeze-drying in the food industry, and vacuum impregnation and drying in the power industry.

This machine is a rotary variable volume vacuum pump that requires a front-end pump to be used in a wide pressure range, with a high pumping speed and insensitivity to dust and water vapor in the extracted gas. Widely used in industries such as metallurgy, chemical, food, and electronic coating. Mainly used as the main pump for vacuum units, it requires the assistance of a front-end pump. For example: water ring vacuum pump, slide valve vacuum pump, vertical oil-free vacuum pump, molecular vacuum pump, etc. The domestic Roots vacuum pump maintains a record of 20000L/S.
