4 Operation
Read the instructions carefully and pay special attention to the warnings!
4.1
Important check and monitoring during operation
Daily checks
-
Shaft seal (SSS and DMS)
If leakage from the shaft seal can lead to dangerous situations, daily visual inspection for leakage is recommended.
-
If leakage is detected the risk should be evaluated and maintenance of the seal should be planned accordingly.
Other checks
Motor
-
The bearing life is heavily dependent on the operating condition of the pump i.e. pressure, ambient temperature, motor
load and pressure variations.
-
The motor should be serviced according to the guidelines in the motor instruction manual
-
The motor should be relubricated with the intervals given in chapter 6.6 “Reblurication intervals”.
In order to detect motor bearing failure, the condition of the bearings must be monitored regularly.
It is recommended that the condition of the bearings is checked every 2000 hours of operation.
The condition of the bearings can be be monitored in several ways eg. by means of vibration analysis (shock pulse
measurements).
After checking the bearing condition, it must be evaluated if it is OK to continue or else maintenance of the bearings must be
planned accordingly.
