龙宝娱乐YIBANLAISHUO,ZAOCHENGDONGBEIDAIZAIBUNENGTISHENGDEZHUYAOYUANYINWEI:  

1、油研A3H系列柱塞油泵配件严重磨损。在低速运转时泵内泄漏严重;高速运转时,泵压力稍有提高,但由于泵的磨损及内泄,容积效率显著下降,很难达到额定压力。液压泵长时间工作又加剧了磨损,油温升高,由此造成液压元件磨损及威格士油泵配件龙宝娱乐的老化、损坏,丧失密封能力,液压油变质,最后导致故障发生。  

2、液压元件选型不合理。动臂油缸规格为70/40非标准系列,威格士油泵配件龙宝娱乐亦为非标准件,制造成本高且威格士油泵配件更换不便。动臂油缸缸径小,势必使系统调定压力高。

3、液压系统设计不合理。操纵液压油研液压泵配件与全液压转向器为单泵串联,安全油研液压泵配件调定压力分16MPa,而油研A3H系列柱塞油泵配件的额定工作压力也为16MPa。液压泵经常在满负载或长时间超负荷(高压)情况下工作,并且系统有液力冲击,长期不换油,液压油受污染,加剧液压泵磨损,以致液压泵泵壳炸裂(后曾发现此类故障)。
