Fluorine plastic self-priming pump with axial back to the pump body structure. The pump body is composed of a suction chamber, a liquid storage chamber, a scroll chamber, a liquid return hole, a gas-liquid separation chamber and the like. After the pump is normally started, the impeller sucks the liquid stored in the suction chamber and the air in the suction pipe together, Within the full mixing, the centrifugal force, the liquid entrained gas flow to the outer edge of the scroll chamber, the outer edge of the impeller formed on a certain thickness of the white foam belt and high-speed rotating liquid ring. Gas-liquid mixture through the diffuser into the gas-liquid separation chamber. At this point, due to a sudden drop in the flow rate, the lighter gas is separated from the mixed gas and the gas continues to rise through the pump spit. The degassed liquid returns to the liquid storage chamber and re-enters the impeller through the return hole. The degassed liquid re-mixes with the gas sucked in from the suction pipe inside the impeller and flows to the outer edge of the impeller under the action of a high-speed rotating impeller. As this process goes on and off, the air in the suction line is continuously depleted until the gas is exhausted and the process of self-priming is completed. The pump is put into normal operation. Fluorine plastic self-priming pump at the bottom of the bearing body can also be equipped with cooling room. When the bearing heat causes the bearing body temperature rise more than 70 degrees, through the cooling room at any one of the coolant pipe fittings, cooling fluid injection cooling. Pump inside to prevent the liquid from the high-pressure zone to the low-pressure zone leakage seal mechanism is the front and rear seal ring, the front seal ring mounted on the pump body, the rear seal ring mounted on the bearing body, when the pump running seal ring wear to a certain extent, and Affect the pump efficiency and self-priming performance, should be given replacement.
