5、数值表(理论数值,未考虑ηmh祁ηv;近似值)
Table of values (theoretical values without considering n mh and ny;values rounded)
注∶以上值在吸油口的绝对压力为1bar时有效,如果流量减小或进口压力增加,转速可增加。Notes.:Values shown are valid for an absolute pressure cof 1 bar at suction port.If the flow is reduced or if the inlet pressure is increased the speed may be increased.
油液Fluid
1、工作介质Fluid∶MR20S(Q/TCNK12-2001)
2、工作粘度范围 Operating viscosity range
为了得到最佳效率和使用寿命,我们建议工作粘度(在工作温度下)在一下范围中选择∶
v opt=最佳工作粘度16mm2/s~36mm2/s
针对油箱温度(开式回路)
For optimum efficiency and service life we recommend thatthe operating viscosity (at operating temperature) be selectf in the range:
v opt=opt. operating viscosity 16~36mm2/s
referred to tank temperature (open loop circuit). 极限粘度范围Limits of viscosity range
在极端工况下,下列数值有效∶(The following values are valid for extreme operating conditions∶)
v min=10 mm2/s
短 时,在80℃的最高允许漏油温度下
for short periods at max. leakage oil temperature of 80℃v min=1000mm2/s
短时,冷启动时for short periods upon cold start.
3、温度范围Temperature range tmin=-20℃; tmax=+80℃
4、过滤Fi Itration
为了保证轴向柱塞泵的正常运作,最低清洁度等级为∶ISO4406之16/19级,这可通过安装过滤器来实现,油泵回油过滤精度为10um。
In order to ensure reliable operation of the axial piston unit,theoperating fluid must be maintained to a cleanliness class of at least: 16/19 to ISO4406. This may be achieved with filter elements, cleanliness class of pump leakage fluid 10um。
