The transport of cutting fluid on machine tools
Centrifugal pumps use the rotation of the impeller to cause centrifugal movement of water to work. The basic structure is composed of eight parts, namely: impeller, pump body, pump cover, water retaining ring, pump shaft, bearing, sealing ring, stuffing box, and axial force balancing device. Before starting a water pump, it is necessary to fill the pump casing and suction pipe with water, and then start the motor to drive the pump shaft to rotate the impeller and water at high speed. The water undergoes centrifugal movement and is thrown towards the outer edge of the impeller, flowing through the flow path of the volute pump casing into the pressurized water pipeline of the pump.
