With the high-pressure centrifugal pump running time and aging equipment, the pump before and after the high temperature of the bearing, burned often appear. In response to this emerging cost phenomenon, 208 oil production team at Hekou Oil Production Plant installed a thin oil lubrication pump for high-pressure centrifugal pumps to force lubricate the front and rear bearings of the pump. The device through the oil back and forth cycle to increase the flow rate to reduce the bearing temperature, to solve the bearing bush phenomenon. With a thin oil lubrication device, the pump remains in good operating condition. Not only save costs, but also ensure the pump open rate.
