另外,使用具有尺寸圖所示尺寸的吸管。 如果泵安裝在上面
油箱液位,將吸入口從油位設(shè)定在1.0米(3.3英尺)以下)。
3.啟動(dòng)時(shí)的注意事項(xiàng)
在初始操作或長(zhǎng)時(shí)間休息後的操作中,泵可能難以吸入流體。
在這種情況下,排氣側(cè)應(yīng)預(yù)先安裝排氣閥(型號(hào)ST1004 - * - 10
*,目錄號(hào)公佈。 EC-3001),或者通過(guò)放電側(cè)的連接略微鬆弛來(lái)排出空氣。
啟動(dòng)時(shí),盡可能間歇地運(yùn)行泵。
對(duì)於啟動(dòng)時(shí)的流體粘度,請(qǐng)參見“液壓油”一文

Note: Only Petroleum Base Oils can be used for hydraulic fluids.
2. Recommended Viscosity and Oil Temperature
Viscosity ranging between 20 - 400 mm2 /s (100 - 1800 SSU).
Oil temperatures between 0/+70°C (32 - 158°F)
Use hydraulic fluids which satisfy the recommended viscosity
and oil temperatures given above.
Note that if the PVL1 pump is started at a low speed of 950
r/min, the maximum fluid viscosity is limited to
200 mm2/ s (910 SSU).
