水轮机、舰船螺旋桨和水泵等高速运转的水力机械经常会发生汽蚀现象。汽蚀现象不但降低了水力机械的效率和使用寿命,而且还使水力机械遭受严重破坏,直接威胁安全生产。当城市自来水供水水泵应用XCA型复合材料以后,不但可使单位电耗下降2.62～8.1%,水泵出水量净增57～120T/h,而且还能明显地延长水泵的使用寿 Cavitation often occurs at high speed hydraulics such as turbines, ship propellers and pumps. Cavitation not only reduces the efficiency and service life of hydraulic machinery, but also seriously damages the hydraulic machinery and directly threatens the safety in production. When the city water supply pump XCA-type composite materials, not only can make the unit power consumption decreased by 2.62 ~ 8.1%, the water pump net increase of 57 ~ 120T / h, but also significantly extend the life of the pump
