Zhongtian Closed-Loop Liquid Ring Vacuum Systems integrate liquid ring vacuum pumps with gas-liquid separation, working-liquid recirculation, heat exchange, instrumentation and control equipment into complete process-vacuum solutions. The operating liquid discharged from the vacuum pump is separated from the process gas, cooled through a heat exchanger and returned to the pump for recirculation. This arrangement significantly reduces fresh-water consumption and wastewater discharge while maintaining controlled operating-liquid temperature for stable vacuum performance. Each system is custom engineered according to the required pumping capacity, operating pressure, gas composition, vapour load, working-liquid properties and site utility conditions.
Working Principle
The operating liquid discharged from the vacuum pump is separated from the process gas in the gas-liquid separator. The separated liquid is cooled through a heat exchanger and returned to the vacuum pump for recirculation. By controlling operating-liquid temperature, level and circulation conditions, the system maintains stable operating conditions for the liquid ring vacuum pump. System configuration is determined by the required pumping capacity, operating pressure, gas composition, vapour load and site utility conditions.
