高压油泵首要用途是作为千斤顶、镦头器、挤压机、扎花机等液压设备的动力源。高压油泵的设备次第如下：在设备高压油泵的过程中，为避免杂物落入机器内，机组的全部孔穴均应盖好。将机组放在埋有地脚螺栓的基础上，在底座与基础之间，用成对的楔垫用校正用。校正泵轴和电机轴的同心度，在联轴大道外圆上，容许差错0.1毫米;两联轴器平面的空地应保证2～4毫米，(小泵取小值)空地要均匀，允差0.3毫米。

泵油过程可分为以下两个阶段。

进油过程

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

回油过程

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。

PVM控制选项

压力补偿器控制-代号A

在预先调整的补偿器压力下，泵将提供连续调整的流量，满足变化的负载要求。压力低于补偿器设定值，泵将工作在较大排量。警告：压力补偿器可能调整得超出泵的额定压力，在调整压力限制器时，在出油压力表口上安装 0-350bar(0-5000 )压力表，限制压力设定值在针对泵排量的连续额定压力，

压力补偿器控制(代号A)的压力截流特性在50 C(120 F ) 静态工况。

负载传感和压力补偿器控制-代号B或C

泵将提供和系统负载要求相匹配的泵输出功率，使安装在泵和负载之间的任何方向控制阀达到较**率，并且改善负载节流特性。

负载传感保证泵总是只提供负载需要的流量，同时泵的工作压力调整到实际负载压力加控制动作所要求压差，当系统不要求功率

时，负载传感控制将处于节能备用模式。通常，压差是压力进口和比例方向阀（或负载传感方向阀）的工作口之间的。针对负载传感的压差设定值见B-48页的型号编码。如果负载压力超过系统压力设定值，压力补偿器减小泵的排量。负载传感管路必须尽可能短，并且还能用于泵压力的远程控制或卸载。为了远程控制，建议您向我们咨询www.eaton6.com。警告：压力补偿器可能调整得超

出泵的额定压力，在调整压力限制器时，在出油压力表口上安装0-350 bar(0-5000)压力表，限制压力设定值在针对泵排量的连续额定压力

柱塞卡死在泵体里，用手扳动离合手柄，凭感觉判断柱塞是否卡死。如果分离轻松，说明柱塞弹簧处于压缩状态，柱塞已经卡死在泵体里。柱塞卡死的原因有三：①油泵工作时间较长，负荷较大，或长时间空泵，或配合间隙过小，润滑不良，温度过高等原因均可造成柱塞卡死。如果拉伤严重，应更变新泵；如果拉伤轻微，应用细砂布把拉伤处磨光，可继续使用。②新安装的油泵容易发生柱塞卡死现象，这主要是固定油泵的三个螺栓拧紧力矩不一致造成的，可把三个螺栓稍微拧紧。使油泵位置轻微移动，然后均匀拧紧三个螺栓即可。③液压油里杂质较多，使柱塞与泵体配合面损伤而卡死。
