Magnetic Grate

After the high-pressure pump start, Magnetic Grate when the pressure reaches 16 ~ 18MPa, the ball floated Simplified 0.13 ~ 0.18 mm, then you can start the mill. 15 min later, the ring gear and small Adequately lubricated gears, mill at 0.4 MPa of low pressure lubrication operation. Because job working operation or electrical problems, and sometimes high-pressure oil pressure does not reach a predetermined Oil pressure or high-pressure pump there is a problem to force the mill started at a lower pressure. At this point the host mill bearing pad is closely integrated with the state of the hollow shaft, friction Large, if start mill, not only easy to scratch pad, and a small gear due to localized sudden impact, prone to the phenomenon of broken teeth.The second reason for broken teeth: No disk drive or disk drive enough time
