柱塞向上供油,当上行到柱塞上的斜槽(停供边)与套筒上的回油孔相通时,泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通,油压骤然下降,出油阀在弹簧力的作用下迅速关闭,停止供油。此后柱塞还要上行,当凸轮的凸起部分转过去后,在弹簧的作用下,柱塞又下行。此时便开始了下一个循环。
柱塞泵以一个柱塞为原理介绍,一个柱塞泵上有两个单向阀,并且方向相反,柱塞向一个方向运动时缸内出现负压,这时一个单向阀打开液体被吸入缸内,柱塞向另一个方向运动时,将液体压缩后另一个单向阀被打开,被吸入缸内的液体被排出。这种工作方式连续运动后就形成了连续供油 。
采用补油泵供油的柱塞泵,使用3000h后,操作人员每日需对柱塞泵检查1-2次,检查液压泵运转声响是否正常。如发现液压缸速度下降或闷车时,就应该对补油泵解体检查,检查叶轮边沿是否有刮伤现象,内齿轮泵间隙是否过大。对于自吸油型柱塞泵,液压油箱内的油液不得低于油标下限,要保持足够数量的液压油。液压油的清洁度越高,液压泵的使用寿命越长。

泵依靠旋转叶轮对液体的作用把原动机的机械能传递给液体。由于离心泵的作用液体从叶轮进口流向出口的过程中,其速度能和压力能都得到增加,被叶轮排出的液体经过压出室,大部分速度能转换成压力能,然后沿排出管路输送出去,这时,叶轮进口处因液体的排出而形成真空或低压,吸水池中的液体在液面压力(大气压)的作用下,被压入叶轮的进口,于是,旋转着的叶轮就连续不断地吸入和排出液体。

液压油缸安装
1开箱:油缸内封有气化性防锈剂,所以,在装配前不得拆下入口的塞子。如果拆下塞子,必须立即安装在机体上,而且在油缸内放满油
2防锈:油缸安装在机体上以后,如果活塞在伸出的情况下放置时,必须在活塞杆的露出部分涂敷油脂。
3速度:一般规格的油缸,当动作速度超过2m/s时,其使用寿命将会受到影响。以0.3m/s作为冲程末端的场合,为了保护机构和安全起见,建议内部安装缓冲机构。另外,使油缸停止时,为了保护油缸机构和安全起见,线路上也必须考虑,以防止发生很大的冲击。为了增加油缸的回油量,线路设计时应该特别注意。在0.5m/min以下低速运转时,将会影响到动作性(特别是振动),所以,低速运转时,应该进行洽谈。
4运转:运转初期,必须完全排清油缸内的空气。残留空气的场合,采取低速充分运转,排除空气。如果油缸内残留空气受急剧夹压时,那么,由于液压油的作用,有可能使密封圈烧损。另外,动作中如果油缸内部产生负压,那么,将有可能由于气蚀作用而发生异常。

液压配管
(1)根据压力及使用场合选择油管,油管须有足够的强度,内壁应光滑、清洁,无沙、无锈、无氧化皮,对于长期贮存的管子,加工前应酸洗,完全清洗、冲刷,并进行检查。
(2)用锯切断管子时,断面与轴线方向的不垂直度应为±0.5°,锐边须倒钝并清除铁屑,加工弯曲管时允许其断面的椭圆度为10%。当其外径<14mm时可用手和一般工具弯管,较粗钢管宜用手动或机动的弯管机弯管,弯管半径一般应比管子外径大3倍。
(3)安装管路要求是,线路较短,转弯尽可能要少,管路的较高部分应设排气装置,以便启动时放气。
(4)安装橡胶管时,应避免急转弯,其弯曲半径R≥(9~l0)D(D为软管外径)。不要在靠近接头根部折弯,要求软管接头至开始弯曲处的距离L≥6D。软管工作时不应扭转。
(5)吸油管不得漏气,也不应阻力太大,以防进气或吸油困难产生气蚀。
(6)回油管口须伸到油箱油面以下,防止飞溅产生气泡。溢流阀的回油管不能直接和泵的入口连通,一定要通过油箱,否则油温将会过高。
(7)全部管路安装程序分两次进行,先进行试装配,将管接头及法兰点焊在合适位置上,当全部管路试装合格后,拆下来进行酸洗后再正式安装。
