There are many types of lining pump structure, among which, the working principle of external mixing lining pump is: before starting, the pump shell is filled with water (or there is water in the pump shell itself). After starting, the impeller rotates at high speed to make the water flow in the impeller channel flow to the volute. At this time, the inlet forms a vacuum, which opens the inlet backstop door, and the air in the suction tube enters the pump, and reaches the outer edge through the impeller channel.
Working principle
The water discharged into the air-water separation chamber by the impeller flows back to the outer edge of the impeller through the left and right backwater holes. Under the action of pressure difference and gravity, the water flowing back from the left backwater hole is shot into the impeller channel and smashed by the impeller. After mixing with the air coming from the suction pipeline, the water flowing back to the volute. The acid-resistant fire pump of the gear pump of the metering pump of the vacuum pump is flowing in the direction of rotation. Then it joins with the water coming from the right backwater orifice and flows along the volute. Because the liquid continuously impacts the cascade in the volute and is broken by the impeller, it is stirred and mixed with the air to form a mixture of gas and water, and the gas and water can not be separated because of the continuous flow. The mixture is peeled off by the tongue at the volute outlet and enters the separation chamber along the short tube. The air in the separation chamber is separated and discharged by the outlet pipe, while the water still flows to the outer edge of the impeller through the left and right backwater holes and mixes with the air in the suction pipe. So repeated circulation, gradually exhaust the air in the inhalation pipeline, so that water into the pump, complete the self-priming process.
