부유 펌프 배출 방향식 밸판 구멍은 어떤 설계인가요?

使辅助油泵出口油路一直存油，防止长时间不启，造成泵出口到单向阀处存气。油压降低，辅助油泵自启时，油压出现波动

那这样造成的辅油泵缓慢反转有没有什么影响？会不会造成启动时电流过大

泵反转是不允许的，不论大泵还是小泵，我觉得是不是1-1.5mm的油孔还是有点大

反转是不正常的是否限流孔变大了?

轻微反转可以的，为什么要开孔上面都说得很清楚了，另外一个原因就是在主泵运行时，保证辅助泵这边始终有油流动，保证温度，不然事故情况下需要启动辅助油泵，但泵温度低，可能会使泵抱住损坏

长期冲刷会不会这个孔越变越大呢？据说2013年开工初期是不反转的，什么时候开始反转的说不清楚

可以拆开测量一下孔径的大小应该可以查图纸对比一下开孔是没问题的很多机组都这么设置
