*力士乐手动换向阀、力士乐柱塞泵 力士乐柱塞泵之变量柱塞泵A11VO/A11VLO 用于开式系统;规格:40至260,系列1:名称压力:350bar;尖峰压力:400bar。 力士乐柱塞泵特性: 力士乐柱塞泵主要应用于混凝土泵车 铲运机械、混凝土机械、路面机械、压实机械及起重机械等工程机械领域。力士乐柱塞泵在自吸条件下,油箱加压或带升压泵(离心泵)工作。力士乐柱塞泵可提供多种变量机构用于不同的控制和调节功能。力士乐柱塞泵即使机器运行时也可经外部来设定功率控制。力士乐柱塞泵可带有通轴驱动以承装齿轮泵或直到相同规格的轴向柱塞泵(100%通轴驱动)。力士乐柱塞泵输出流量与驱动转速及泵排量成正比,并可在zui大与零之间无级变化 A11VL0130LRDS/10R-NZD12K01 A11V0130LRDH2/11R-NZD12K02 A11VL0160LRDH2/11R-NZD12K02 力士乐柱塞泵 力士乐 柱塞泵 力士乐高压柱塞泵 高压柱塞泵 专业销售REXROTH博士力士乐系列产品,*,货期快捷,欢迎选项购! 任何欧美自动化产品均可以找我们来报价!

力士乐液压系统漏油会造成液压量减少且不能建立正常油压,从而导致系统不能正常工作。液压系漏油有外漏和内漏2种情况。外漏主要是油管破裂、接头松动、紧固不严密等情况等造成的;内漏主要是液压系统内部的油泵、油缸、分配器等产生泄漏造成的。内漏的故障不易被发现,有时还需借助仪器进行检测和调整,才能排除。

    1、 齿轮油泵相关部位严重磨损或装配错误

    (1)油泵齿轮与泵壳的配合间隙超过规定极限。处理方法是:更换泵壳或采用镶套法修复,保证油泵齿轮齿顶与壳体配合间隙在规定范围之内。
 
    (2)齿轮轴套与齿轮端面过度磨损,使卸压密封圈预压缩量不足而失去密封作用,导致油泵高压油腔与低压油腔串通,内漏严重。处理方法是:在后轴套下面加补偿垫片(补偿垫片厚度一般不宜超过2mm),保证密封圈安放的压缩量。

    (3)拆装油泵时,在2个轴套(螺旋油沟的轴套)结合面处,将导向钢丝装错方向。处理方法是:保证导向钢丝能同时将2个轴套按被动齿轮旋转方向偏转一个角度,使2个轴套平面贴合紧密。

    (4)在拆装油泵时,隔压密封圈老化损坏,卸压片密封胶圈被装错。处理方法是:若隔压密封圈老化,应更换新件:卸压片密封胶圈应装在吸油腔(口)一侧(低压腔),并保证有一定的预紧压力。如装在压油腔一侧,密封胶圈会很快损坏,造成高压腔与低压腔相通,使油泵丧失工作能力。

    2、油缸密封圈老化和损坏活塞杆锁紧螺母松动

    (1)油缸活塞上的密封圈、活塞杆与活塞接合处的密封挡圈、定位阀密封圈损坏。处理方法是:更换密封圈和密封挡圈。但要注意,选用的密封圈表面应光滑;无皱纹、无裂缝、无气孔、无擦伤等。

    (2)活塞杆锁紧螺母松动。处理方法是:拧紧活塞杆锁紧螺母。

    (3)缸筒失圆严重时,可能导致油缸上下腔的液压油相通。处理方法:若失圆不太严重,可采取更换加大活塞密封圈的办法来恢复其密封性;若圆度、圆柱度误差超过0.05mm时,则应对缸筒进行珩磨加工,更换加大活塞,来恢复正常配合间隙。

    3、分配器上的安全阀和回油阀关闭不严

    (1)安全阀磨损或液压油过脏;球阀锈蚀,调节弹簧弹力不足或折断;液压油不合规格;液压油过稀或油温过高(液压油的正常温度应是30℃~60℃),都会使安全阀关闭不严。处理方法是:更换清洁的符合标准的液压油;更换规定长度和弹力的弹簧;更换球阀中的球,装入阀座后可敲击,使之与阀座贴合,并进行研磨。

    (2)回油阀磨损严重或因液压油过脏而导致回油阀关闭不严。处理方法是:研磨锥面及互研阀座。若圆柱面严重磨损,可采取镀铬磨削的方法修复;若小圆柱面与导管磨损,造成内隙过大,可在导管内镶铜套,恢复配合间隙。清洗油缸,更换清洁的液压油。

     滑阀与滑阀孔磨损,使间隙增大,油缸的油在活塞作用下从磨损的间隙处渗漏,流回油箱。处理方法是:镀铬后磨削修复,与滑阀孔选配。
