What are the classification criteria for centrifugal pumps? | |
Centrifugal self priming pumps become more and more popular pumping solutions in the world because of their straightforward, smooth performance, effective design, low maintenance requirements, and convenient operation. The machines adopt one or more impellers that rotate synchronically with the pump shaft to increase the fluid's pressure head and move it. They are used in a variety of industrial and marine applications and are suitable for pumping clean, low-viscosity fluids such as water, fuels, oils and chemicals. Close and Long Coupled Centrifugal Pumps There are many other types of centrifugal pumps, but we will concentrate on the two most common configurations, close-coupled and long-coupled pumps. The centrifugal pump coupling plays a crucial role in selecting a pumping solution because it directly impacts power, efficiency, and even pump maintenance. However, the closed-coupled pumps are less ideal for heavy-duty and high-power applications as they have one set of bearings, which puts additional strain on the bearings and the size of the motor is typically restricted. As a result, the long-coupled pumps are suitable for demanding, continuous-use applications like cooling and water circulation. The motor and pump can be installed on separate shafts and kept apart by a coupling thanks to the long linked centrifugal pump design. In this manner, the operating strain is shared by the individual bearings, increasing the mechanical parts' lifespan. Furthermore, because there is a lot of space between the head and the motor on long coupled centrifugal pumps, fluid leakage and motor damage are prevented. In a word, although close-coupled centrifugal pumps are dependable pumping options, they are usually chosen for less demanding working environments and situations requiring a cost-effective and compact pump. Vertical Inline Pump and Horizontal Pump The choice of horizontal versus vertical pump ultimately boils down to application requirements and convenience. Although each type of centrifugal pump has advantages of its own that you should consider, their operation is essentially the same. The location of the shaft is the primary distinction between centrifugal pumps that are horizontal and vertical. The shafts of horizontal centrifugal pumps are usually positioned horizontally, either overhung or between the bearings, while the shafts of vertical inline pumps are vertical, meaning they are radially split and overhung. When installing and attaching the pump to the existing pipes, this unique pump feature is crucial. You also need to be aware of the need of pump maintenance. Because of the way they are made, compact vertical centrifugal pumps are challenging to maintain and repair, which means doing so requires lifting the pump each time. Therefore, vertical inline pumps are usually chosen for certain uses and situations in which space is limited. Conversely, horizontal pumps are more widely utilized due to their ease of installation and maintenance. They can also be safely connected to external accessories like electric motors and turbines, and they offer simple access to the interior components. Compared to vertical centrifugal pumps, this type of pump has a bigger footprint and operates at a lower pressure and temperature. Single Stage and Multistage Pump Centrifugal pumps are classified into single-stage and multistage pumps based on the quantity of impellers. Their impellers are primarily different, yet this has a big impact on how well the pump works. The multistage centrifugal pump achieves far higher pressure capabilities than a single impeller because it contains numerous impellers that are placed and rotated on the same shaft. As the flow moves from one impeller to the next, the head increases by the same amount. This means that multi-stage centrifugal pumps are typically used in applications that require high-pressure capabilities, including moving fluids over very long distances. Conversely, single-stage centrifugal pumps are easy to maintain, operate steadily, are highly efficient, and offer a sizable flow capacity. They are made for uses where a high flow rate is more crucial than pressure tolerance. Furthermore, one of the most widely used types of centrifugal pumps is the single-stage pump, which comes in a variety of materials and design options to suit different application needs. Single-stage pumps are extremely dependable and low maintenance options, making them perfect for applications where the pump must handle big volumes, such as general water transfer and ballast water pumping. | |
