油泵：是一种既轻便又紧凑的泵，提出了一种具有一个由含铝材料制成的外壳的油泵和设置在该外壳中的可运动的模制件，其中，该可运动的模制件至少部分地由一种可烧结的、至少包含一种奥氏体的铁基合金的材料制成，并且其中由一种可烧结材料制成的该模制件具有一个至少为该外壳的热膨胀系数60%的热膨胀系数。
 
齿轮油泵在试机运行时应注意事项：
1、安装帮浦的轴心不得承受任何的径向或是轴向压力。
2、油泵启动前务必将油泵内填满液压油后再进行空载（无负载）运转，确认液 压油有吸上来。
3、先试运转开关寸动瞬间即停3-5次，确认旋转方向的正确性。
4、正式运转时必须800rmp-1000rpm，油泵内部吸入油流速才能使泵内部瞬间得 到油的足够量才不会使油泵内零件磨损。
5、若运转时出现油流未正常流出即刻停止运转，就是因为管路内有空气存在而 产生真空现象，以致油泵不能顺利将油供出。
6、若发现真空现象就要在油泵出油口或是进入油路块位置的油管适度放松，油 泵再运转发现有油流出即可锁死油管正式运转，这只是排除油管内真空的一种 方法。
7、先在无压力下试运转3-5分钟后渐进加压，调适30kg/㎡时在运转数分钟， 70kg/㎡再试运转数分钟，直*机台使用*高压力为止。
