the Use of centrifugal pumps is practiced in a variety of industries, systems, utilities, agriculture, mining and in many other areas that require pumping or pumping fluid. The operation of centrifugal pumps perform extremely reliably, giving them an advantage over most other products.
working Principles of centrifugal pumps
the Fluid from the reservoir is drawn with the help of pressure difference generated by the device. Once in the pump casing within which rotates the impeller, the water due to the centrifugal force is displaced to the periphery of the device. In the center of the pump centrifugal force and, accordingly, the pressure is lower than at the periphery. Due to the difference of these parameters, the liquid moves further and is displaced through the discharge pipe. In the centre there is a free place where re-circulated liquid, and this process does not stop until the pump is in operation.
There are single and multi-sectional pumps. One unit in the liquid immediately from the body enters the pipeline in multiple - — from section to section, and from there into the pipe. There are also pumps with a different number of impellers. If the wheels some, they shaft are connected in series.
Main advantage centrifugal pump in front of the piston is that the device does not have to overcome inertial forces and therefore, the efficiency of centrifugal pumps is much higher. In addition, the simple design of this pump makes it particularly reliable and durable, its simple to fix and install, maintenance of such devices also is not true for complex processes. Here, for example, rotary and reciprocating pumps is more complicated to manage, and their installation and repair is much more time.
To centrifugal pump, you can attach additional devices, it can pump not only clean water, but of liquid of a different composition, including impurities (e.g., oil). Also such pumps, in contrast to, for example, from rotary screw models — can be run without fluid.
Also, centrifugal pumps are popular due to low cost and availability of spare parts. Design of a centrifugal pump is to recognize the most optimal and universal, so these devices in the near future are unlikely to be driven out of the market.
