To make sure bearing operated well, we must use LGHP2 grade high temperature lubrication grease. Before adding new lubrication grease we should clean the input hole.Commonly, bearing will have natural temperature increase by 1-2 days just after lubricating or second lubrication.To avoid dust fall into oil input hole, or wear bearing, usually we’ll use oil cup to cover oil hole.
If we operate the drilling waste management after long time off status, we need to inspect motor rotary unit on insulation. Use 500V Ω gauge, get resistance is not larger than 0.5MSZ, we can run the Desilter.
Notice: If the motor doesn’t run at all, we must shut off the power immediately to avoid motor broken.After starting motor, to inspect, whether this is any problem. If there is any break off or uncommon noise. If two motors are not running in-phase we need to stop the motors and get rid of problems then turn it on again for operation.. When mud system is under cold status, should not be started 5 times continuously; when motor is turned off under hot status, the restart can not be over 3 times continuously.
