和不二越液压一起来说说液压泵的研发与使用

发布时间:2018-12-07 浏览次数:5668


不二越液压产品中IPH,PVS系列液压泵在挖掘机行业应用非常广泛,国内三一等挖掘机知名厂家也合作紧密,下面一起来简单聊聊挖掘机液压泵行业中的那些事情

现在的挖掘机各项技术还不是十全十美的,还有很多地方需要一步步的改进的,比如液压柱塞泵还有十项技术缺陷,是现代技术不能攻克的,有待于今后的科技发展来解决。十项技术缺陷之一,就是现代的液压柱塞泵使用压力低,科学家的理想“泵”与“马达”使用压力是要达到60Mpa。转速达到6000转以上,如能达到上述状态,科学家设计的挖掘机是:一台发动机带动一台发电机,发电机带动一台直流伺服变频电机,一台直流伺服变频电机带动一台小型“定量柱塞泵”。
99电玩挖掘机使用动作需要快时,伺服变频电机达到最高转速,定量泵的输出油排量也最大,挖掘机使用动作需要慢时,伺服变频电机达到低转速,定量泵的输出油排量变小,这样,省去了泵的变量部份,泵的体积有很大的减小,故障点也随着减小。挖掘机的液压力变大后,最大的好处是:同样的一台挖掘机的挖掘力变大,挖斗也会加大,挖掘更有力了。
