The working principle of a centrifugal pump is to use the rotation of the impeller to create centrifugal motion in the water. Before starting the pump, the pump casing and suction pipe must be filled with water, and then the motor is started to drive the impeller and water to rotate at high speed. The pressurized water flows into the water pipeline of the pump.
The working principle of a centrifugal pump is to use the rotation of the impeller to create centrifugal motion in water. Before starting the pump, the pump casing and suction pipe must be filled with water, then the motor is started to drive the pump shaft, causing the impeller and water to rotate at high speed. The pressurized water flows into the pump's discharge pipeline.
The basic structure of a centrifugal pump consists of eight parts: impeller, pump body, pump cover, wear ring, pump shaft, bearing, sealing ring, and stuffing box, as well as an axial force balancing device. The characteristic curve of a centrifugal pump is an inherent property of the pump itself and is unrelated to external factors. However, once the pump is arranged to work in a specific pipeline system, its actual working condition is not only related to the characteristics of the centrifugal pump itself but also depends on the working characteristics of the pipeline. Therefore, when selecting and using a centrifugal pump, it is also necessary to consider the characteristics of the pipeline.
Centrifugal pumps can be widely used in industries such as power generation, metallurgy, coal, and building materials for transporting slurries containing solid particles. For example, in thermal power plants for hydraulic ash removal, in metallurgy for ore slurry transportation, and in coal washing plants for coal slurry and heavy medium transportation. When placed in water, it is necessary to start the water pump. Slurry pumps and submersible centrifugal pumps are limited by their structure. During operation, the motor must be placed above the water surface while the pump is submerged in water, so it must be securely fixed. Otherwise, the motor may fall into the water and become unusable. Additionally, due to the generally fixed length of long shafts, installation and use of the pump can be quite troublesome, limiting its application scenarios.
