Operation and precautions of circulating water multipurpose vacuum pump

Many users know the circulating water vacuum pump, but they don't know how to use it correctly Today, let Gongyi Yuhua editor introduce the application and matters needing attention 1 Place the machine on the workbench, open the water tank cover to inject clean cold water, and stop adding water when the water surface is about to rise to the height below the overflow nozzle behind the water tank When the machine is started repeatedly, check the water level If the water level is not enough, add water 2 For vacuumizing operation, connect the air extraction pipe sleeve of the equipment to be vacuumized closely to the air extraction nozzle of the unit, check that the circulating water switch should be closed, turn on the power supply, turn on the power switch, and then start vacuumizing operation, and observe the vacuum degree through the vacuum meter corresponding to the air extraction nozzle 3 When the machine needs continuous operation, the temperature in the water tank will rise, which will affect the vacuum degree At this time, the drain hose can be connected with the tap water, the overflow nozzle can be used as the drain port, and the appropriate tap water flow can be used to keep the temperature in the water tank from rising, so as to stabilize the vacuum degree 4 When it is necessary to provide cooling circulating water for the reaction device, connect the water inlet and water outlet pipes of the device to be cooled to the circulating water outlet and water inlet nozzles at the rear of the machine respectively, and open the circulating water switch to realize the circulating cooling water supply Gongyi Yuhua Instrument Co., Ltd is a multi-purpose vacuum pump manufacturer engaged in circulating water for many years It provides you with professional technical personnel, training or remote guidance There are professional technical consultants to answer various questions about the multi-purpose vacuum pump for circulating water Please contact our technical experts at any time
