Any kind of machinery has its imperfections, slurry pump there is a cavitation problem. The following describes the slurry pump cavitation. Slurry pump cavitation is a very complex issue. His principle mainly involves the knowledge of physics, but also involves a small number of chemical phenomena: a certain part of the head of the impeller when the pump is operating is the lowest flow pressure position, when the local liquid pressure drops to equal Or lower than the vapor pressure at the time of the temperature, the liquid flow there will be vaporized to produce bubbles. Bubbles filled with steam and some of the active gas (such as oxygen), which is released from the liquid and dispersed in the bubbles, act as a higher pressure fluid around the bubbles as the bubbles enter the pump to the higher pressure area with the liquid , The bubbles are compressed and deformable and collapse, resulting in a huge condensation shock that is intrinsically explosive. When bubble collapse occurs at the wall of the runner, a fine jet is generated which impinges on the wall at high velocity to create a localized high pressure on the wall (tens to hundreds of megapascals) A blow. If the bubbles continue to collapse and collapse, the formation of a continuous hit on the metal material, so the metal surface is quickly eroded due to fatigue. In addition, due to the erosion of the metal protective film continues to be destroyed, in the heat of condensation, the bubble in the liquid from the active gas precipitation and metal corrosion caused by chemical corrosion. The formation, development and collapse of the above bubbles, so that the flow through the wall was destroyed, known as cavitation cavitation pump cavitation problem is very complex, but with the continuous development of modern science and technology, at the same time Slurry pump parts match. Will reduce the impact of this problem on the slurry pump, and even finally to eliminate cavitation.
