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, utilizing the pumped solvent as the working fluid of the liquid ring vacuum pump to achieve vacuum extraction.
• Principle
The extracted gas enters the liquid ring vacuum pump through the suction port, is compressed within the pump, and then mixed with some working fluid before entering the gas-liquid separator for separation. The gas is discharged through the exhaust port, while the working fluid is recirculated by the liquid ring pump after passing through a heat exchanger.

The system generates heat during operation, including: heat from the intake gas; heat released during the compression of the intake gas; and the inefficiency of the vacuum pump's power. The closed-loop circuit 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 sets of equipment, easy to install, significantly reducing the user's installation cycle.
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. The system can be designed to meet customer requirements, and it is a non-standard product.
