Centrifugal pump is the use of a centrifugal impeller rotation and make the water has come to work. Pump before the start, it is necessary to make the pump casing and suction tube filled with water, and then start the motor, make and water pump shaft to drive the impeller for 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.

The basic construction of centrifugal pump is composed of six parts, respectively, impeller, pump body, pump shaft, bearing, seal ring, stuffing box.

1, is the core part of a centrifugal pump impeller, strength higher than that of its speed, on 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.

2, the pump body also calls the pump shell, it is the body of the pump. Support fixed effect, and connected to install bearing bracket

3, the role of pump shaft is connected by coupling and motor, the torque of the motor to the impeller, so it is a major part of the mechanical energy transfer.

4, sliding bearing is using a transparent oil as lubricant, fuel oil level to the line. Too much oil to the pump shaft seepage, too little bearing overheating and burn out cause an accident! Bearing in the process of pump working in 85 degrees, the highest temperature is generally run around 60 degrees Fahrenheit.

5, sealing ring, also known as minus leakage ring.

6, stuffing box is mainly composed of filler, seal ring, filler tube, packing gland, water tubes. The role of the stuffing box is mainly in order to close the gap between pump casing and pump shaft, don't let the pump in the flow outside to not let outside air into the pump. Always keeping the vacuum inside the pump! When the pump shaft and be about to rely on water seal packing friction heat to hold water to the water seal circle packing cooling! Keep the pump running. So in the process of pump run Tours of inspection to check the stuffing box is paying special attention to! Running about 600 hours will be carried out on the packing replacement.
