力士乐REXROTH油泵特点:力士乐柱塞泵根据倾斜元件的不同,有斜盘式和斜轴式两种。斜盘式是斜盘相对回转的缸体有一倾斜角度,而引起柱塞在泵缸中往复运动。传动轴轴线和缸体轴线是一致的。这种结构较简单,转速较高,但工作条件要求高,柱塞端部与斜盘的接触部往往是薄弱环节。斜轴式的斜盘轴线与传动轴轴线是一致的。它是由于柱塞缸体相对传动轴倾斜一角度而使柱塞作往复运动。流量调节依靠摆动柱塞缸体的角度来实现,故有的又称摆缸式。
(1)保证油箱油面在规定的高度上,吸油管、回油管应保证在油面以下,且中间有隔板。
(2)防止系统内出现一个大气压以下的低压现象。
(3)经常检查密封装置是否损坏,管接头及各接合面处螺钉是否拧紧。
(4)液压缸上部等处要设排气阀。
