How to Fill Self-priming Pump with Oxygen

Unscrew the inflatable nut on the pressure tank, and add oxygen to it with a pump, so that the pressure tank can stabilize the pressure. Install a check valve at the outlet of the automatic suction pump or replace the check valve. Filling a pressure tank with oxygen is similar to inflating tires and basketball. However, it is generally unnecessary, and the pressure tanks manufactured by manufacturers have pre-charging pressure. It is necessary to disconnect the water system and be independent, and not to exceed the system pressure, otherwise the spring will be useless if it cannot be pressed down. Pressure tank is a prerequisite for the water pump to go to sleep. Using the minimal compressibility of water, water is stored in the tank by external force, and the gas is compressed and the pressure increases. When the external force disappears, the compressed gas expands to remove water. The pressure tank is mainly composed of valve cover, inflation port, airbag, carbon steel tank and flange. When it is connected to the water system, it mainly acts as an accumulator. Pressure1.5-3.5kpa.
