Summary
The liquid ring vacuum pump closed-loop circulation system, as a complete set of equipment, integrates the liquid ring vacuum pump, gas-liquid separator, heat exchanger, frame, and internal piping accessories, using the pumped solvent as the working fluid for the liquid ring vacuum pump to achieve vacuum extraction.
• Principle
The gas drawn enters the liquid ring vacuum pump through the suction port, is compressed by the pump, and then mixed with some working fluid before being separated inside the gas-liquid separator. The gas is discharged through the exhaust port, while the working fluid is recirculated by the liquid ring pump after being reconditioned in the heat exchanger.

The system generates heat during operation, including: the heat of the inhaled gas; the heat released during the compression of the inhaled gas; and the inefficiency of the vacuum pump power. The closed-loop structure affects the release of heat. The main function of the heat exchanger is to cool the working fluid with cooling water, maintaining the working fluid temperature within a reasonable range.
• Advantages
Complete set of equipment, easy to install, significantly shortening the installation cycle for users.
2. The working fluid can be recycled using water or various chemical solvents, reducing environmental pollution in the chemical industry.
3. If the extracted medium is used as the working fluid, the extracted medium can be recycled.
4. Systems can be customized to meet customer requirements; they are non-standard products.
