The quality of the seal affects the overall performance of the entire mixing plant equipment, therefore, it is very important to choose a good seal, the root cause of the ash leakage of the shaft end of the mixing plant equipment is the damage of the floating seal, due to the damage of the seal ring and the oil seal, the lubrication system is short of oil, resulting in the wear of the sliding wheel hub and the rotating wheel hub.

Bearing wear due to shaft end leakage and friction with the mixing spindle leads to excessive shaft end temperature. The main shaft end of the mixing plant is the part of the stress concentration, and the service life of the parts will be greatly reduced under the action of high strength stress. Therefore, it is necessary to replace the sealing ring, oil seal, sliding hub and rotating hub in the shaft end sealing device in time.

Mixing plant equipment spindle end leakage, the end side of the bearing is recommended to be the original sealing accessories, to avoid size differences can not be installed, or wear quickly after installation, thus damaging the large shaft.

In addition, the lubrication system should be checked in time: lubrication system main oil pump rotating shaft wear phenomenon; The pressure gauge interface plunger of the main oil pump of the lubrication system does not work normally; The valve spool of the progressive oil distributor safety valve is blocked in the lubrication system and cannot distribute oil.
