Emergency lubrication:Electric motor running at nominal, constant speed. Consequences for emergency lubrication:-

15、Increased specific feed rate at part load.- Same feed rate as in normal mode at 100% load only with pump speed factor = 1!- Pump speed factor 1: Feed rate at 100% load is lower compared to normal mode.- Pump speed factor 1: Feed rate at 100% load is higher compared to normal mode.- Em. lubrication n

Berchtold / 11.07.01,The feed rate can be adjusted by changing the so called pump speed factor in the RC system. The parameter should be within 0.85 and 1.15. By changing the pump speed facto

17、r, the feed rate can be adjusted in very small steps.Only the total amount can be adjusted. It is not possible to adjust the upper / lower level or single units The other possibility is to adjust the setting screws on the lubricator. Here the upper or lower lubrication level can be adjusted separate

18、ly. Also single cylinders can be adjusted separately.The feed rate will change in big steps.,How to adjust the cylinder lubrication,CLU3,WCH / Licensing / 4067 / M.
