柱塞泵是液压系统的一个重要装置。
它依靠柱塞在缸体中往复运动，
使密封工作容腔的容积发生变化来实现吸油、压油。
柱塞泵具有额定压力高、结构紧凑、和流量
调节方便等优点，被广泛应用于高压、大流量和流量
需要调节的场合，诸如液压机、工程机械和船舶中。

液压阀的辅助加工技术的分析

液压件辅助加工主要包括：阀体清砂、零部件去毛刺、去热处理残渣和清洗等内容
1、阀体类的清砂
国产液压阀阀体绝大多数以球铁、蠕铁、灰铁为材质，以树脂砂作为造型介质翻砂浇铸而成，具有体积小、结构紧凑、形状复杂和精度要求高等特点，铸件的质量很大程度上决定了液压阀的档次。阀体因以砂为造型材料，故铸件中不可避免地有粘砂存在。粘砂对液压系统来说危害性较大。清除粘砂的方法较多，国内常用的液压泵有滚筒清砂、喷丸清砂、电化学清砂和水爆清砂等。喷丸清砂一般用于油道敞开或油道较大的阀体类及粗加工后阀体的清砂，它不但能去除粘砂，还可去除锈迹和粗加工产生的毛刺，特别是液体喷砂，还能起光饰铸件表面作用。电化学清砂是利用（SiO2）与熔融的NaOH起电化学反应生成偏硅酸钠和水，能较净地去除窄小油道内的粘砂，故喷丸和电化学清砂这两种方法作为阀体铸件精细去砂的方法，广为各生产厂家采用。但这两种清砂方法也有不足之处：⑴喷砂清砂适用于较大油腔或油道敞开的阀体，对结构复杂、油道细小的阀孔等有较大的局限性，不能有效去除粘砂，且对已加工表面较易造成破坏，故而影响密封性、美观性和产品精度，且不利于加工工序的安排；⑵电化学清砂对一些非循环腔而言很难有效去净粘砂，且能耗较高，对环境破坏，工人的作业强度也高，故对复杂件的清砂大家还在探索之中。
2、滑阀类零件去毛刺及去热处理残渣
液压件辅助工序另一大问题是去机加工毛刺、热处理残渣等。毛刺的存在，将对液压件造成不良影响，如阀杆卡紧、阻尼孔堵塞，特别是镀铬类阀杆平衡槽中的磨削，毛刺随油液径向液动力的作用窜入阀杆与阀孔的间隙中，不但不能起消除液动力的作用，反而会导致阀杆卡紧、操作力加大或系统压力不稳定、微动性能与压力调制性能下降。
机加工时应采用合理的切削参数来控制毛刺的产生，对产生的毛刺则应安排工序去除，去毛刺方法有：手工操作法、振动光饰法、砂带磨削法、铜丝轮或磨光机抛光法、不锈钢丝刷抛光法、液体喷砂法等。方法的选用应视实际情况而定。相对来说，阀体类零件采用带球尼龙刷或不锈钢丝刷去除阀孔毛刺，即在精细铰之前用手电钻装夹刷子去除割槽、粗铰等序所产生的毛刺。砂带或铜丝轮对去阀体外表面磨削毛刺及锈迹较为理想，对于一些较粗的磨削飞边应先用钢锯条刮除，内腔其它毛刺可采用液体喷砂法清理，对于淬火零件可用的工具或钢丝刷去除，淬火后氧化物等一般可以用振动光饰法或酸洗去除，当然酸洗时应根据不同的材质采用不同的酸液并加入适宜的脱脂剂和缓蚀剂。
3、液压阀零件的清洗
