Centrifugal force is a virtual force, a manifestation of inertia, which keeps a rotating object away from its center of rotation. With the progress of the industrial level, there are devices that begin to use centrifugal force to accomplish their work, and centrifugal pumps are a typical example. The centrifugal pump is a device that uses the impeller to rotate and cause the water to work with centrifugal motion. Currently, centrifugal pumps are used in a wide range of applications. But still some do not know how to properly use the centrifugal pump, this article will do a brief introduction and analysis of the centrifugal pump. The operation of the centrifugal pump will be highlighted in this article.
·The working principle of centrifugal pumps.
·The precautions when using centrifugal pumps.
·The centrifugal pump applications.
The principle of submersible centrifugal pump is very simple, during the work of centrifugal pump, it relies on the rotating impeller in the process of rotation, due to the interaction between the vanes and the liquid, the vanes will transfer mechanical energy to the liquid, so that the pressure energy of the liquid increases, to achieve the purpose of transporting liquid.
There is a limit to the head produced by a centrifugal pump at a certain speed. The working point flow rate and shaft power depend on the condition of the device system connected to the pump and the head changes with the flow rate. In addition, centrifugal pumps are started with the discharge line valve closed, and vortex and axial pumps are started with the valve fully open to reduce the starting power.
The weight of the pipeline should not be added to the pump during installation, and it should have its own support body, so as not to make the deformation affect the operation performance and life. At the same time, before installing the pump, you should carefully check whether there are hard objects in the pump runner that affect the operation of the pump, so as not to damage the impeller and pump body when the pump is running.
Check that the rotation direction of the motor is consistent with the rotation direction specified in the pump. When testing the direction of rotation of the motor, the motor should be tested alone, not in conjunction with the multi stage pump.
The above are the main operating precautions for centrifugal pumps. In addition to the above-mentioned precautions, for the convenience of maintenance and safety of use, we recommend installing a regulating valve on each of the pump's import and export pipelines and a pressure gauge near the pump outlet, which is to ensure operation within the rated head and flow rate.
Centrifugal pump has a wide range of applications, it centrifugal pump can be widely used in electric power, metallurgy, coal, building materials and other industries to transport slurry containing solid particles. For example, thermal power plant hydraulic ash removal, metallurgical beneficiation plant slurry conveying, coal washing plant coal slurry and heavy medium conveying, etc. It should be noted that the characteristic curve of centrifugal pump is the inherent characteristic of the pump itself, and it has nothing to do with the external use.
