Failure Analysis of Drum Screening Machine


1.It is found in the faults of some drum sand screening machines that when the spherical bearing contacts the inner surface of the sand screening machine, the contact conditions of the conical spindle and the cone bushing also change, which will affect the stability of the sand screening machine. Scraping and grinding the spherical bearing so that the sand sieve and the spherical bearing can contact the outer ring.
2.When the amount of oil in the drum sand screening machine is insufficient, check whether the lower cover of the frame, the transmission bearings and flanges, the oil pipe joints of the dust protection device are leaking, and whether the oil inlet pipe and the oil filter are blocked. Is the oil tank oil level appropriate, and the oil pump’s oil intake is normal? Once a problem is found, it should be resolved as soon as possible.
3.The gap between the main shaft of the drum sand screening machine and the tapered bushing should meet the technical standards.If the gap is too small, a method of adding a gasket between the spherical bearing frame and the annular contact surface of the body frame can be adopted to raise the sand screening machine In order to change the gap between the main shaft and the conical bush, so as to meet the technical requirements.
