        可以杜绝泵的过度发热和油温过高的现象。另外,回油过滤器堵塞造成回油背压过高,也会引起油温过高和泵体过热。常见故障处理(5)变量调节机构螺栓松动,密封破损;柱塞泵工作原理(5)变量调节机构螺栓松动,密封破损;当凸轮的凸起部分转过去后,在弹簧力的作用下,柱塞向下运动,柱塞上部空间(称为泵油室)产生真空度,当柱塞上端面把柱塞套上的进油孔打开后,充满在油泵上体油道内的柴油经油孔进入泵油室,柱塞运动到下止点,进油结束。进油过程现在生产柱塞泵的厂家很多,进口件和国产件结构不尽相同,每一台泵都应严格按照其出厂使用说明书使用。在维修泵时,首先应该检查泵在系统中的安装、使用是否得当,便于及时查出损坏原因,消除隐。 柱塞弹簧被压缩,柱塞向上运动,燃油受压,一部分燃油经油孔流回喷油泵上体油腔,当柱塞顶面遮住套筒上进油孔的上缘时,由于柱塞和套筒的配合间隙很小(0.0015-0.0025mm)使柱塞顶部的泵油室成为一个密封油腔。

        由于放大器能量不足或零件损坏、含有弹簧的控制活塞的阻尼器效能差,都会造成控制活塞运动不稳定。流量不稳定又往往伴随着压力波动。这类故障一般要拆开液压泵,更换受损零部件,加大阻尼,提高弹簧刚度和控制压力等。变量式轴向柱塞泵的斜盘倾角为零时称为中位,此时泵的输出流量应为零。但有时会出现中位偏离调整机构中点的现象,在中点时仍有流量输出。其原因是控制器的位置偏离、松动或损伤,需要重新调零、紧固或更换。泵的角度维持力不够、倾斜角耳轴磨损也会产生这种现象。输出流量波动与很多因素有关。对变量泵可以认为是变量机构的控制不佳造成,如异物进入变量机构,在控制活塞上划出阶痕、磨痕、伤痕等,造成控制活塞运动不稳定。由于放大器能量不足或零件损坏、含有弹簧的控制活塞的阻尼器效。 柱塞泵工作原理(2)泄漏量过大,原因是泵的间隙过大,密封不良造成,如配油盘被金属碎片,铁屑等划伤,端面漏油,变量机构中的单向阀密封面配合不好,泵体和配油盘的支承面有砂眼或研痕等,可以通过检查泵体内液压油中混杂的异物判别泵被损坏的部位。

        柱塞内推时,工作室压力升高,进口阀关闭,高于出口压力时,出口阀打开,液体排出。当传动轴带动缸体旋转时,斜盘将柱塞从缸体中拉出或推回,完成吸排油过程。柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。变量机构用来改变斜盘的倾角,通过调节斜盘的倾角可改变泵的排量。振动和噪声是同时出现的。它们不仅对机器的操作者造成危害,也对环境造成污染。(1)输出压力过低当泵在自吸状态下,若进油管路漏气或系统中液压缸、单向阀、换向阀等有较大的泄漏,均会使压力升不上去。这需要找出漏气处,紧固、更换密封件,即可提高压力。溢流阀有故障或调整压力低,系统压力也上不去,应重新调整压力或检修溢流阀。如果液压泵的缸体与配流盘产生偏差造成大量。 充满在油泵上体油道内的柴油经油孔进入泵油室,柱塞运动到下止点,进油结束,如泵轴和电机轴不同心或顶死,旋转轴的轴承,联轴节损伤,弹性垫破损和装配螺栓松动均会产生噪声,对于高速运转或传输大能量的泵,要定期检查。
