全新原装力士乐泵A4FO250 30R-PPB25N00

A4FO型定排量泵，轴向柱塞泵

A4FO型为斜盘结构的轴向柱塞定量泵﹐适用于开式回路的液压驱动。

输出流量与驱动转速及排量成正比—好的吸入性能

-低噪声

-长寿命

-可以组合成多联泵一在驱动通轴上可另装泵

油液

为了评论A4FO型泵选用的液压油液的适应性﹔详细的油液兼容性和应用数据可在RC 90220(矿物油)、RE90221(环保液压油液)和RC 90223 (阻燃液压油液·HF)的样本活页中找到。采用HF-或环保液压油液时﹐必须考虑到此油液可能使其工作参数受到限制·如需﹐欢迎向我公司的技术部门垂询。(请在订货单上指明你的液压系统所用液压油液的品种型号)。

系列16...40的A4FO型定量泵﹐不能用HFA ·HFB或HFC油液工作。

工作粘度范围

为了得到最佳的效率和工作寿命﹐推荐把油液的工作粘度(在工作温度下)选在下列范围内∶

Vopt = 16...36 mm2/s

选用液压油的注意事项

为了选用正确的液压油﹖必须知道油箱(开式回路)的工作温度和环境的温度的差距。

必须选择液压油液﹐以保证在工作温度范围内油液的工作粘度处于最佳范围(v。)(见选择图的阴影部分)。建议在每种场合﹐均选用最高可能的粘度等级。

示例:在XC的环境温度下﹐工作温度为60℃·在最佳工作粘度范围(v﹔阴影部分)内﹐对应有VG46或VG68·应选VG68 。

注意∶泄漏油(壳体泄漏油）温度受压力和泵的转速的影响并总是高于油箱温度。然而﹖系统任何地方的温度对于规格16...40不得超过115℃﹐对于规格

71...500不得超过90℃ 。

如果由于极端的工作参数或过高的环境温度而不能满足上述条件,欢迎垂询。

油液的过滤

过滤越精细﹐则油液的清洁度越高﹑轴向柱塞元件的寿命越长。

为了保证轴向柱塞元件的正常功能﹐需要清洁度至少为∶

NAS1638 ,等级9

ISO/DIS 4406的18/15

在很高的油液温度下(90C至最大到115℃,对于规格71...500不允许)清洁度至少为

NAS1638,等级8ISO/DIS 4406的17/14
