controlling pressure, and maintaining flow. However, one of the most common problems that arise with pumps is cavitation. Cavitation can be a major problem that can cause damage to the pump, increase maintenance costs, and reduce overall efficiency. In this...
A major concern for the engineers who design and utilize these machines is to avoid cavitation — where the fluid undergoes sudden phase changes that can physically damage mechanisms. Pump cavitation can harm internal mechanisms. To prevent this, engineers need to ensure that the right equipment is...
This white paper explains how cavitation occurs and is intended to serve as a reference when selecting pumps, planning pump stations and understanding cavitation-related complications in the field.doi:10.1016/S0262-1762(18)30146-9NoneWorld Pumps...
However, bespoke pump designs offer a custom approach to help avoid cavitation damage by addressing specific end-user requirements and effectively minimizing cavitation risks. Smooth Flow pumps like the KNF FP 7 offer outstanding low pulsation and therefore can help minimize the risk of pump ...
In addition to pressure and flow, the curve at the bottom of Figure 4 indicates NPSHr, which stands for Net Positive Suction Head Required. NPSHr is the minimum amount of pressure required on the suction side of the pump to avoid cavitation, or the introduction of air into the fluid strea...
Cavitation in pumps is caused by excessively low pressure at the pump inlet. A blockage or restriction such as a clogged filter or part-closed valve mounted on the inlet to the pump can cause it. It can also happen when the pump has to source its water supply from a sump in...
气蚀是指当局部压力迅速降低到液体的蒸汽压力以下时,在液体内部形成蒸汽腔(气泡)。这就在液体内部形成了一个蒸汽泡,这个蒸汽泡通常会持续很短的时间,然后又破裂成液体 破裂过程是很剧烈的,产生巨大的爆裂声,并经常损坏附近的表面。即使是坚硬的金属也会在受到气泡内爆所产生的强烈的局部喷射时出现凹陷。

This is attributed to the frequent local pH decreases can disrupt the balance between tooth mineralization and demineralization in the closed microenvironment of the biofilm17. Consequently, this leads to mineral loss in teeth, resulting in white spots, cavitation, pulp infections, and even tooth ...
