The centrifugal pump uses an impeller inside a tube to boost fluid pressure. These pumps are primarily employed in a variety of applications that demand a large amount of fluid discharge and pressure. Positive displacement pumps are useful for trapping a particular amount of fluid in a reservoir before it is transported into another pipe, whereas horizontal and vertical centrifugal pumps are useful for transporting fluids from one place to another. These pumps might develop a variety of difficulties as a result of their frequent use, affecting their operational functions.
Problem with Motor
Inconsistent pump operation can lead to a variety of issues with the electric motor that drives the impeller rotation. The rotating movement between the parts of the motors is accomplished using a variety of components. It is critical to replace these parts if they are damaged. If the impeller rotates in the wrong direction, the motors’ polarity must be reversed.
Erosion of Impeller
Pump vibration and High pitched noise is a clear indicator that impeller is eroded. Debris entering the impeller is the most common cause of impeller erosion. Corrosion occurs as the impeller’s ceramic pieces are chipped away. It is critical to replace the impeller in order to resolve this issue.
High Viscosity Liquid
Low discharge pressure and a shortage of liquid delivery to the pump might lead to thick or viscous pump fluid. To solve this problem, warm the pumped liquid until it softens and flows more easily.
Due to high temperatures and heat, the shaft may expand. When the pump is operating, the shaft may come into touch with the restriction bush, causing wear and tear on all components in the vicinity.
Cavitation is another problem that can occur in a centrifugal pump. The liquid flowing through the pump raises the flow velocity while lowering the flow pressure. The liquid might cause bubbles to form inside the pump, reducing the pump’s performance. Cavitation is the name for this process, which can harm other sections of the pump and irreversibly ruin the pump set.
These pumps can become unbalanced for a variety of causes. Some of the most common causes include shaft and impeller misalignment, external elements, corrosion, and many other problems. While operating, an imbalanced pump will shake violently. Other elements of the pump may loosen as a result, causing significant harm to the overall component.
Misalignment of the pulley:
In pulley-driven pumps, a misaligned pulley can create major issues. The pump’s revolving parts can make close contact with the stationary parts, causing complications. This can have an impact on pump performance since it damages the machine’s components.
Avoid these Problems with Regular Pump Maintenance
Maintaining your pump regularly will help you to ensure that it is in good working order. It is also capable of lowering the cost of revenue repair due to a productivity issue. You can spend a lot of money on repairs if you don’t maintain your pumps properly. Furthermore, a poorly maintained pump will be unable to provide adequate output. It may be the source of reduced productivity. As a result, preventive maintenance is critical. You can take a look at some of the most important aspects to consider when performing regular maintenance. Lubricating bearings, adjusting motor couplings, testing and fixing seals, and ensuring that the pumped is properly placed on the base are all part of monthly maintenance.
Meanwhile, annual maintenance includes inspecting the pump for bearings, drive belts, and any other damaged parts and adjusting, fixing, or replacing them. It’s also crucial to do a vibration and temperature investigation to check the pump’s overall condition. There are some strategies you can use to improve the pump’s efficiency, such as using a small booster pump. This sort of pump may maintain production while downsizing the larger pump when it is no longer needed.
The Bottom Line
When kinetic energy is transferred into the liquid that is pumped via the pipes, centrifugal pumps work. Problems and malfunctions are unavoidable because these pumps work with a variety of sophisticated attachments. Because technical knowledge is required to fix these pumps, it is critical to seek the help of skilled professionals for maintenance.
