进口双螺旋自吸泵characteristic:

The self-priming pump is a self-priming centrifugal pump. The working principle of the self-priming pump is to fill the pump casing with water (or there is water in the pump casing itself) before the pump is started. After the pump is started, the impeller rotates at a high speed to make the water flow in the impeller channel flow to the volute. At this time, the inlet forms a vacuum, so that the inlet check valve opens, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel. It has the advantages of compact structure, convenient operation, stable operation, easy maintenance and high efficiency It has the advantages of long service life and strong self-priming capacity. The pipeline does not need to be installed with a bottom valve. Before operation, it is only necessary to ensure that there is a fixed amount of liquid in the pump. The traditional self-priming pump adopts the pump body structure of axial liquid return. 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, etc. after the pump is started normally, the impeller sucks the liquid stored in the suction chamber and the air in the suction pipeline together, and gets complete mixing in the impeller. Under the action of centrifugal force, the liquid entrains the gas to the outer edge of the scroll chamber, A white foam belt with a certain thickness and a high-speed rotating liquid ring are formed on the outer edge of the impeller. The gas-liquid mixture enters the gas-liquid separation chamber through the diffusion pipe. At this time, due to the sudden decrease of the flow rate, the lighter gas is separated from the mixed gas-liquid, and the gas continues to rise and be discharged through the discharge port of the pump body. The degassed liquid returns to the liquid storage chamber and enters the impeller again through the return hole. It mixes with the gas sucked in from the suction pipe inside the impeller and flows out of the impeller again under the action of the high-speed rotating impeller. As the process goes on, the air in the suction pipeline is continuously reduced until the gas is exhausted. After the self suction process is completed, the pump is put into normal operation

进口双螺旋自吸泵Principle:

The sealing check valve is composed of a thickened diameter O-ring and a circular cake shaped valve disc in the middle, which is connected by a rectangular parallelepiped piece above it. The circular cake shaped valve disc is wrapped with a circular metal block, and the sealing check valve is processed with soft rubber material. At the moment when the pump is stopped, the valve disc of soft rubber material can stop the liquid in the pump shell under the action of heavy force. The thickened O-ring ensures a good sealing effect between the water inlet section and the pump shell, It can achieve one-time liquid filling and life-long self-priming. At the same time, it seals the integral structure of the check valve, which also replaces the functions of the sealing gasket and the check valve in the prior art. It is convenient to install and saves costs;
