液压泵过度发热有两个原因：一是机械摩擦生热。柱塞泵由于运动表面处于干摩擦

或半干摩擦状态，运动部件相互摩擦生热。二是液体摩擦生热。高压油通过各种缝隙泄漏到低压腔，大量的液压能损失转为热能；长期负荷过大导致卸荷阀频繁开启，油缸或阀有内泄（阀内部磨损，缸密封不好）；阀或管道有堵塞现象。所以正确选择运动部件之间的间隙、油箱容积和冷却器，可以杜绝泵的过度发热和油温过高的现象。另外，回油过滤器堵塞造成回油背压过高，也会引起油温过高和泵体过热。 

液压泵转速高，排油压力高，工作环境恶劣，油液污染、油液选用不合规定或油液过少，都可造成泵损、泄漏。泵内泄漏可使其功率损失加大，磨损严重。油液中侵入空气后易于压缩，可造成泵干磨。液压泵内长时间的泄漏、干磨或压缩厉害， 必然发热，引起油液升温，造成系统发热。 

变量液压泵的伺服变量机构损坏也会造成系统发热，工作元件无力，或是系统过载,导致发动机、电动机闷车甚至停止工作 

伺服变量机构损坏，假如不能变量了，必然导致系统高压溢流，长期从而导致发热！伺服变量机构损坏有两种表现：不变量，过早变量。不变量导致系统过载，因为此时变量泵相当于定量泵。此时功率和压力成正比；过早变量，相同的压力时，系统流量变小，显得工作元件无力，系统工作速度变慢。假如伺服阀不能换向了那么液压泵就只能始终在较大排量下工作，

自然会发热。定量泵 溢流阀。

柱塞泵除具有自吸能力、流量与排出压力无关等特点外，泵壳上无吸A阀和排出阀，具有结构简单，流量均匀、工作可靠等特性，但效率低、噪音和振动大、易磨损，用来输送无腐蚀性、无固体颗粒并且具有润滑能力的各种油类，温度一般不超过70’℃，例如润滑油、食用植物油等。一般流量范围为0.045～30ms/h，压力范围为0.7—20MPa，工作转速为1200—4000r/min。

A10VG45EP4D1/10R-NTC10F023ST-S力士乐柱塞泵柱塞泵的泵油机构包括两套准确偶件：柱塞（plunger） 柱塞套(barrel)构成柱塞偶件(plunger and barrel assembly)（图5-11）、出油阀（delivery valve）和出油阀座(delivery valve seat)构成出油阀偶件(delivery valve assembly

柱塞和柱塞套是一对准确偶件，经配对研磨后不能互换，要求有高的精度和光洁度和好的耐磨性，其径向间隙为0.002～0.003mm

柱塞头部圆柱面上切有斜槽，并通过径向孔、轴向孔与顶部相通，其目的是改变循环供油量；柱塞套上制有进、回油孔，均与泵上体内低压油腔相通，柱塞套装入泵上体后，应用定位螺钉定位。
