Cavitation is the formation of vapor bubbles in a centrifugal pump due to low pressure. NPSH stands for Net Positive Suction Head.

• Cavitation occurs when the pressure at the pump inlet drops below the vapor pressure of the liquid, causing the formation of vapor bubbles.

• These vapor bubbles collapse when they reach higher pressure areas, leading to damage to the pump impeller and reduced pump performance.

• Cavitation can be...read more

Surging is a phenomenon in rotating equipment where the flow rate becomes unstable.

• Surging occurs when the flow rate through a rotating equipment fluctuates due to changes in operating conditions.

• It can lead to reduced efficiency, increased wear and tear, and potential damage to the equipment.

• To manage lubrication in different rotating equipment, it is important to monitor and control the flow rate, viscosity, and temp...read more

GTG operation involves multiple generators working together to share the load and ensure continuous power supply.

• GTG stands for Gas Turbine Generator

• In GTG operation, multiple generators are synchronized to work together

• Load sharing ensures that the power demand is distributed evenly among the generators

• This helps in maintaining a stable power supply and prevents overloading of any single generator
