liquid ring vacuum pump

1. Preparation. Place the circulating water multi-purpose vacuum pump flat on the workbench. When using it for the first time, open the upper cover of the water tank and inject clean cold water (you can also add water through the drain hose). Stop adding water when the water surface is about to rise to the height below the overflow spout at the back of the water tank. Repeat the startup to stop adding water. Change the water at least once a week. If the water quality is seriously polluted and the usage rate is high, the water replacement time must be shortened to keep the water in the water tank clean. 2. Vacuuming operation. Tightly connect the suction sleeve of the equipment that needs to be vacuumed to the suction nozzle of the 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 circulating water multi-purpose vacuum pump 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 appropriately controlling the tap water flow, the water temperature in the water tank will not rise and the vacuum degree will be stable. 4. When it is necessary to provide cooling circulating water for the reaction device, based on the previous operation in item 3, connect the water inlet and outlet pipes of the device that needs to be cooled to the circulating water outlet and water inlet at the rear of the machine, and turn the circulating water switch to the ON position to realize the supply of circulating cooling water.
