How many lift can the centrifugal pump 1 stage impeller raise?
The basic structure of centrifugal pump is composed of six parts, namely, impeller, pump body, pump shaft, bearing, sealing ring, stuffing box.1, the impeller is the core part of the centrifugal pump, it is high speed, large output, the impeller blade and play a major role in the impeller before assembly, through the static equilibrium experiment. The inside and outside surfaces of the impeller are required to be smooth, so as to reduce the friction loss of the water flow.2, pump body, also known as pump shell, it is the main body of the pump. The utility model is provided with a supporting and fixing function and is connected with a bracket for mounting the bearing.
When the impeller diameter is the same, the blade outlet increases, the flow rate increases, and the head increases slightly.Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work. The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
3, the role of the pump shaft is to use the coupling and motor connected, the torque of the motor to the impeller, so it is the main component of mechanical energy transfer.4, the sliding bearings are transparent oil used as lubricant, refueling to the oil level line. Too much oil will leak out along the pump shaft, too little, and the bearings will overheat and burn out, which will cause accidents! In the pump running process, bearing temperature is highest at 85 degrees, generally running at about 60 degrees.
