![]() ![]() In some cases, they inadvertently operate with a persistent, albeit mild, cavitation condition. However, many hullpump dredge operators, in their pursuit of maximizing productivity, often tread dangerously close to the realm of cavitation. ![]() The effective vacuum, which represents the disparity between clear water and the maximum vacuum or cavitation threshold, determines the lifting capability of solids into the pump inlet. Vacuum plays a crucial role in understanding the losses encountered at the inlet side of a dredge pump. In this regard, we are here to reveal a reliable method that can unequivocally determine the occurrence of dredge pump cavitation, regardless of its underlying cause. However, there are other less apparent factors that can contribute to cavitation. Many dredge operators are familiar with the evident signs of cavitation, attributing it to suction inlet obstruction or excessive vacuum caused by cave-ins. Cavitation, a widely encountered yet poorly understood phenomenon, poses a significant threat to effective dredge pump operation. ![]()
