Pressure pulsation is the oscillation of pressure in a fluid system. Similar to what you may have experienced during a shower when the pressure suddenly becomes weaker or stronger, pressure pulsation can occur in pipes, valves, pumps, and other fluid-carrying components.
Pressure pulsation can be dangerous for the centrifugal pumps often used in large industrial or wastewater management systems. It can cause several problems, including vibration, erosion, cavitation, noise, and reduced efficiency. In some cases, pressure pulsations can be dangerous. For example, pressure pulsations can cause pipelines to rupture, which can lead to leaks of hazardous or toxic fluids. In centrifugal pumps, pressure pulsations can lead to premature pump failure or damage to other system components.
Centrifugal pumps impart energy to the pumped fluid through the impeller. As the impeller rotates, it accelerates and discharges fluid at a higher pressure. This process can result in turbulence, leading to chaotic changes in pressure and flow. These fluctuations can be more or less severe according to the pump’s design, the type of pumped fluid, and the conditions in which the pump operates.
Pressure pulsation can have several adverse effects on centrifugal pumps, including:
There are several ways to prevent pressure pulsation in centrifugal pumps, including:
