centrifugal pump principle
The series of centrifugal pump refers to the same kind of structure and use pump produced by the pump plant, such as clean water pump, double suction centrifugal pump, chemical pump, slurry pump, pipe centrifugal pump, etc. Select the pump series and materials according to the process parameters and medium characteristics.
Operating principle of centrifugal pump:
The centrifugal pump is used to rotate the impeller to make the water centrifuge 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.
Choose the centrifugal pump to pay attention to:
(1) according to the characteristics of the medium, which characteristic pump should be selected, such as clean water pump, corrosion pump and impurity pump, etc. Medium is highly toxic, valuable or radioactive, etc are not allowed to leak material, should consider to choose no leakage of pump (such as shielding pump, magnetic pump) or with leaking fluid collection and double mechanical seal leakage alarm device. If the medium is liquefied and other volatile liquid should choose low cavitation residual pump, such as pump.
(2) choose horizontal pump and vertical pump according to the selection of installation conditions (including pump under liquid and pipe pump).
(3) select single suction pump, double suction pump, or small flow centrifugal pump according to the flow rate.
(4) select single pump, multi-stage pump, or high speed centrifugal pump according to the height of the head.
