(RA10VO)进口变量柱塞泵 参数值 Parameter value

1、进口工作压力范围Input operating pressure range

油口（S）的绝对压力Absolute pressure at port S（A）

Pabs min.………………0.8bar 

Pabs max……………………………………3bar

2、出口工作压力范围 Output operating pressure range

油口B的压力Pressure at port B

公称压力Nominal pressure PN………………………………280bar 

尖峰压力Peak pressure Pmax……………………………… 350bar 

3、壳体泄油压力Case drain pressure

油液泄油最大压力（在油口L，L1），最多可比S口的进口压力高05bar，但是不能超过绝对压力2bar.Maximum pressure of leakage fluid (at ports L,L1),Maximum 7 psi (0.5 bar) higher than input pressure at port S, but not higher tHan 30 psi(2 bar)absolute. 

4、流动方向 Direction of flow

S至B（StoB）

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。
