Abstract: The authors introduced the power chart analysis technique applied to bearings breakdown monitoring and measurement of the liquid pump in the mineral.By the work condition monitor of the liquid pump with emulsify and the liquid pump lately to the work spot,manufactory,get the normal and standard power diagram of the new pump,old pump and the typical diagram of the bearings breakdown.This is very meaningful the power chart analysis technique spreading to the monitor of the bearings breakdown in the mineral mountain machine's equip.
