注∶以上值在吸油口的絕對壓力為1bar時有效,如果流量減小或進(jìn)口壓力增加,轉(zhuǎn)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、工作介質(zhì)Fluid∶MR20S(Q/TCNK12-2001)
2、工作粘度范圍 Operating viscosity range
為了得到最佳效率和使用壽命,我們建議工作粘度(在工作溫度下)在一下范圍中選擇∶
v opt=最佳工作粘度16mm2/s~36mm2/s
針對油箱溫度(開式回路)
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). 極限粘度范圍Limits of viscosity range
在極端工況下,下列數(shù)值有效∶(The following values are valid for extreme operating conditions∶)
v min=10 mm2/s
短 時,在80℃的最高允許漏油溫度下
for short periods at max. leakage oil temperature of 80℃v min=1000mm2/s
短時,冷啟動時for short periods upon cold start.
3、溫度范圍Temperature range tmin=-20℃; tmax=+80℃
4、過濾Fi Itration
為了保證軸向柱塞泵的正常運(yùn)作,最低清潔度等級為∶ISO4406之16/19級,這可通過安裝過濾器來實(shí)現(xiàn),油泵回油過濾精度為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。
