液压泵内部结构图

柱塞泵：容积效率高、泄漏小、可在高压下工作、大多用於大功率液压系统；但结构复杂，材料和加工精度要求高、价格贵、对油的清洁度要求高。

一般在齿轮泵和叶片泵不能满足要求时才用柱塞泵。还有一些其他形式的液压泵，如螺杆泵等，但应用不如上述3种普遍。

特点

铝合金制造、强度高、耐腐蚀、重量轻、适合各种环境下作业。

双速特性减少了打压次数，在低压室快速处于负载用功状态，立刻转换成高压，缩短每次作业周期。

配有压力调节阀，可调节控制及设定工作压力。组成

液压机械行业常会用到的叶片泵

联轴器

1、联轴器的选用

液压泵传动轴不能承受径向力和轴向力，因此不允许在轴端直接安装带轮、齿轮、链轮，

通常用联轴器联接驱动轴和泵传动轴。如因制造原因，泵与联轴器同轴度超标，装配时又存在偏差，则随着泵的转速提高离心力加大联轴器变形，变形大又使离心力加大。造成恶性循环，其结果产生振动噪声，从而影响泵的使用寿命。此外，还有如联轴器柱销松动未及时紧固、橡胶圈磨损未及时更换等影响因素。

2、联轴器的装配要求

刚性联轴器两轴的同轴度误差≤0.05mm

弹性联轴器两轴的同轴度误差≤0.1mm

两轴的角度误差<1?；

驱动轴与泵端应保持5～10mm距离；

挖掘机是工程机械主力机种，是建设工程的主要生产工具，因此对挖掘机提出了很高的要求。要求节能低排放、**率、良好的操纵性和降低对环境的负荷等，要实现这些要求必须对挖掘机进行控制，由于液压控制信息处理能力差，不能光靠液压控制主要要靠电子控制。液压动力由液压泵提供，要知道液压泵是挖掘机液压系统的能源装置，将电机的机械能转换为液压能，输出流量和压力，在液压系统中占有非常重要的地位。如果液压泵出现故障，将会影响到整个液压系统的正常工作。

挖掘机液压泵流量调整方法与压力调整方法

一、液压泵流量的调整

1、主泵流量的调整

(1)神钢挖掘机200松开流量锁紧螺母；

(2)转动压力调整螺栓，直到压力符合规定为止；

(3)当系统压力在14700一17700kPa范围内时，顺时针转动流量调整螺栓1/4圈，流量增加约18L/min，此时较好级弹簧起作用。当系统压力在23500一34300kPa范闹内时，顺时针转动流量调整螺检1/4圈，流量增加约7L/min，此时第二级弹簧起作用；

(4)若逆时针转动流量调整螺栓，则流量减少相应的数镇；

(5)拧紧流量锁紧螺母，拧紧力矩为(12加或减3)N?m；

(6)上泵和下泵流量的调整方法相同。

2、中联205挖掘机主泵较大流量的调整

(1)松开流量锁紧螺母；

(2)拧动流量调整螺栓，直到流量达到较大值为止。顺时针转动流量调整螺栓1/49，流量约减少13L/min。逆时针转动流量调整螺栓1/4圈，流量约增加13L/min；

(3)拧紧流量锁紧螺母，拧紧力矩为10N?m。

3、反流量的调整

(1)松开流量锁紧螺母口；

(2)拧动流量调整螺栓，直到流量达到较大镇为止。顺时针转动流量调整螺栓1/4W.在系统压力为2500kPa时，流量约减少41./-n:逆nJ针转动流量调整螺栓1/4圈，流量约增加4L/min；

(3)拧紧流量锁紧螺母，拧紧力矩为(12加或减3)N?m。

油泵可以分为容积式和非容积室（蜗轮式）两种。非容积式有离心泵、轴流泵等，利用高速旋转的叶轮使进口产生真空吸入液体，并在出口连续输出压力液体。这种泵进口与出口相通，效率随液体粘度增加而降低，并且输出液体量随出口压力升高而显著减少。

容积式泵是通过一个封闭的空间容积的变化来实现吸油和压油的。当这个封闭容积由小变大时进行吸油，由大变小时进行压油。典型的为力士乐柱塞泵，柱塞从缸孔中拉出时吸油，压进时压油。这种泵进口与出口是被隔开的，效率取决于隔开吸压油腔的各对运动零件间的结构工艺间隙及油液的粘度等。粘度越率越高，输油量几乎保持不变（因效率略有影响，另外压力升高至18MPa，油液会被压缩1%）。
