随着制造预定为强化工况用的更大型和经济的新式水轮机,提高水轮机的可靠性和寿命则成为特别迫切的问题,其中,经验表明,在工况强化条件下会使过流部件汽蚀磨损急剧增加,从而导致减低机组的效率,缩
Increasing turbine reliability and longevity have become particularly pressing issues with the development of newer and larger turbines intended for use in enhanced conditions where experience has shown that cavitations of overcurrent components can occur under enhanced conditions Abrasion increases sharply, resulting in lower unit efficiency and shrinkage
