1.1 Shaft seal oil drip container, mounting instruction

General

To collect “leakage” oil, which will be released at the shaft seal during operationof a compressor, a drainage system has to be applied. It also prevents soiling thesurrounding area beneath the drive side bearing cover.Be aware that oil leakage at the shaft seal is a normal situation during thecompressor’s operation.Oil has a dual purpose for the proper shaft seal functioning: it both lubricates andcools. A concrete value of the acceptable volume of leakage oil per time unit atthe shaft seal construction is hardly to indicate: it heavily depends on the specificrunning conditions of the compressor. When a significant increase of oil leakagevolume is determined, this could indicate a worn out or damaged shaft seal.If in doubt, please consult your local GEA contact person.The installation of the leakage oil collecting system is easy, but varies slightlywith direct driven or V-belt driven compressors.

Fig.6: Slide the plastic oil collecting bottle into the bracket. Keep a clearance of approx. 1 cm. between thebottle’s bottom and upper side of steel structure. Tighten the screws to fix the bottle

Fig.7: Check if the oil drain pipe at the bearing cover is not blocked by dirt or debris. If so, clean this channel


Fig.8: Slide one side of the plastic hose over the oil drain pipe for approx. 1… 1,5 cm.

V-belt driven compressor

The only difference in application of a drain oil system at a direct drive and V- beltdrive is the position of the collecting bottle. The bracket which holds the plasticbottle has to be fixed to the main support frame next to drive side bearing cover.

Hint!

For mounting procedure (sequency), refer to paragraph "Direct drivencompressor"

Important

Fig.15: To prevent liquid and dirt traps, the hose must be installed in a slope, at all times!
