If it is a self-priming centrifugal pump, you can close the outlet valve before starting, and then fill the water storage tank. When the water is filled to the height of the water inlet, the cover can be covered to prevent air leakage. Start the water pump, let it run for one minute, then slightly open the water outlet valve, so that the steam-water mixture can be gradually removed. When the sound of the water pump becomes dull, the water outlet valve can be completely opened.
