Circulating water vacuum pumpUsing circulating cooling water as a medium, gas or liquid is extracted through a specially designed suction device. It can effectively improve production efficiency, reduce energy consumption, and play an important role in ensuring product quality.

　　Circulating water vacuum pumpThe working water and compressed gas are discharged together, so the water ring needs to be continuously replenished with new cold water to maintain a stable thickness and temperature of the water ring. In addition to serving as a "liquid piston", the water ring also has a heat dissipation effect on the compression process. Simultaneously cooling the sealing shaft seal between the impeller and the valve plate. It is a new type of multi-purpose vacuum pump designed based on the principle of negative pressure generated by jet flow, using circulating water as the working fluid and water added to the water tank for recycling. It can provide circulating cooling water to the reaction device through vacuum conditions and can be used in conjunction with glass reaction vessels and rotary evaporators. It is widely used for evaporation, distillation, and filtration. Decompression, sublimation and other tasks. Small in size, light in weight, and aesthetically pleasing in appearance, it is an ideal equipment for universities, pharmaceutical, chemical, and food processing fields or laboratories.

Preparation before use:

1. Check whether the appearance of the equipment is intact and whether all components are complete.

2. Clean the interior of the vacuum pump to ensure no impurities remain.

3. Connect the power cord to ensure that the power voltage meets the equipment requirements.

4. Install the suction and exhaust pipes, ensuring that the pipe connections are firm and well sealed.

5. Add circulating water to ensure that the water level is not lower than the water level indicated on the pump body, and the water level is close to the height below the overflow nozzle behind the water tank.
