Centrifugal pump working principle and structure are introduced

Working principle of centrifugal pump, is designed according to the principle of centrifugal force, the high-speed rotating impeller blade drive the water rotation, throw the water, water pump before starting, must make the pump casing and suction tube filled with water, and water do the water pump shaft to drive the impeller high-speed rotation, water centrifugal motion, be left to the impeller outer edge and the volute pump shell of the water flow into the pump pressure, so as to achieve the purpose of conveying. Centrifugal pump is mainly composed of pump body, impeller, pump cover, mechanical seal, pump shaft, bearing, bearing box, motor, base and other parts. 1, the pump shell, it is the body of the water pump. Support fixed effect, and connected to install bearing bracket of bearing box. 2, is the core part of a centrifugal pump impeller, the impeller blades and play a major role, the impeller through static balancing experiments before assembly. Impeller on the inside and outside for smooth surface to reduce friction loss of water flow, so as to achieve predetermined parameters requirements. 3, mechanical seal is installed in the pump cover on the periphery of the impeller shaft, sealing effect, the impeller at high speed, liquid will through the clearance between the pump cover and impeller flow out of the pump cavity, installed in the periphery of the mechanical seal can be a very good seal effect, mechanical seal is divided into WB2 and container type double machine. 4, the role of pump shaft is connected to the installation position of coupling shaft coupling and motor, the rotation of the motor to drive the impeller rotation, so it is a major part of the mechanical energy transfer. 5, bearing installed in bearing box, it is set on the pump shaft support pump shaft component, generally has two kinds of rolling bearing and sliding bearing. Along with the continuous improvement of production technology, the company adopts enclosed bearing, without refueling operation, use performance better. Rolling bearing use butter as a lubricant oil is generally appropriate for two-thirds to three-quarters of the volume too much will be fever, too little and there was a noise and fever! Sliding bearing structure of centrifugal pump is using a transparent oil as lubricant, go to the oil level line. 6 and bearing box is connected to the pump and motor parts, and the installation position of pump shaft and bearing, straight league cancelled the bearing box type centrifugal pump, direct connection using stents, pump shaft with motor shaft instead of using short the overall length of centrifugal pump. 7, the base is fixed pump body balance and motor, when using the installation of centrifugal pump is more convenient and quick.
