Usage Of Water Circulation Vacuum Pump

1. Preparation work. Place the circulating water multi-purpose vacuum pump flat on the workbench. When using it for the first time, open the top cover of the water tank and inject clean cold water (or add water through the drain hose). Stop adding water when the water level is about to rise to the height below the overflow nozzle behind the water tank. Repeat the process to stop adding water. Replace the water at least once a week. If the water pollution is severe and the usage rate is high, the time for replacing the water should be shortened to keep the water in the tank clean.
2. Vacuum pumping operation. Tightly connect the suction sleeve of the equipment that needs to be vacuumed to the suction nozzle of this machine, turn off the circulation switch, turn on the power, and turn on the power switch to start the vacuuming operation. The vacuum degree can be observed through the vacuum gauge corresponding to the suction nozzle.
3. When the vacuum pump for circulating water needs to operate continuously for a long time, the water temperature in the water tank will rise, affecting the vacuum degree. At this time, 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 kept from rising, and the vacuum degree can be stabilized.
4. When it is necessary to provide cooling circulating water for the reaction device, based on the third operation above, connect the inlet and outlet pipes of the device that needs to be cooled to the circulating water outlet and inlet nozzles at the rear of the machine, and turn the circulating water switch to the ON position to achieve circulating cooling water supply.
