热水泵产生汽蚀时,过流部件受到腐蚀疲劳损坏,材料产生机械剥蚀,扬程流量降低,产生噪声与振动(泵越大,噪声与振动也越大),严重时,泵组可能引起汽蚀共振。因此,如何解决好汽蚀问题就显得很重要了。1现存问题我冶炼厂中冶炼炉用单级单吸离心泵(IS型)作为热水循环泵冷却炉壁,经过5 When the hot water pump generates cavitation, the overcurrent component is damaged by corrosion fatigue, the material is mechanically ablated, the head flow is reduced and noise and vibration are generated (the larger the pump is, the larger the noise and vibration are). In severe cases, the pump group may cause cavitation Resonance. Therefore, how to solve the cavitation problem is very important. 1 existing problems smelter smelting furnace with single-stage single suction centrifugal pump (IS type) as a hot water circulating pump cooling furnace wall, after 5
