SHB-II circulating water vacuum pump

SHB-IIType circulating water vacuum pump

1Function and purpose

This product is a new type of vacuum pump designed using circulating water as the working fluid and utilizing the principle of negative pressure generated by jet flow. Provide vacuum conditions for chemical experiments and be able to supply circulating cooling water to the reaction equipment.

Widely used in evaporation, distillation, crystallization, filtration, depressurization, sublimation and other operations, it is an ideal equipment for laboratories in colleges, pharmaceuticals, chemical engineering, food processing and other fields.

IIProduct Features

1:The water-saving effect is significant. Due to the use of water circulation operation, the water added to the water tank can be recycled, overcoming the phenomenon of directly using tap water to obtain vacuum and wasting a large amount of tap water.

2:Multi functional comprehensive use. In addition to providing vacuum conditions, this machine can also automatically circulate water to provide circulating cooling water for the reaction device.

3:This machine is equipped with two exhaust nozzles, which can operate separately or simultaneously. Each suction nozzle is equipped with a vacuum gauge, which allows for easy observation of the vacuum level.

4:Corrosion resistant and pollution-free. The water pump of this machine is made of stainless steel, and the water tank is made of stainless steel or anti-corrosion material,Not affected by corrosive substances such as acid and alkali. At the same time, there is no oil pollution or other contamination in the laboratory.

5:This machine works stably and reliably, with low noise.

4、 Usage:

1Preparation work. Place the machine flat on the workbench. When using it for the first time, open the top cover of the water tank and inject clean cold water. Stop adding water when the water level is about to rise to the height of the overflow nozzle behind the water tank. Repeat the process to stop adding water.

2.Vacuum pumping operation. Tightly fit the suction sleeve of the equipment that needs to be vacuumed onto the suction nozzle of this machine. Connect the power supply, turn on the vacuum switch, and start the vacuuming operation. The vacuum degree can be observed through the vacuum gauge corresponding to the vacuum nozzle.

3.When the machine needs to operate continuously for a long time, the water temperature in the water tank will rise, affecting the vacuum degree. At this point, the water discharge hose can be connected to the water source (tap water), and the overflow nozzle can be used as the drainage outlet. By controlling the flow rate of tap water appropriately, the water temperature in the water tank can be maintained and the vacuum degree can be stabilized.

4.Circulating water operation: When it is necessary to provide cooling circulating water for the reaction device, connect the inlet and outlet pipes of the device that needs to be cooled to the outlet and inlet nozzles at the rear of the machine, and turn on the circulating water switch to achieve circulating cooling water supply.
