During the operation of the automatic mixer, abrasion problems are easy to occur due to abrasion, erosion, impact, micro vibration, sliding and other factors, which affect the stable and safe operation of the electromagnetic brake of the automatic mixer, and even frequent operation failures.
The causes of wear failure of automatic mixer mainly include the following aspects. First of all, the closed enclosure was not set up, because the automatic mixer truck vibrated, overfilled, eccentric loading, sand and dust, which caused the bucket aggregate to leak, cement and sand to leak into the brake and wear the brake disc.
With the continuous increase of cement and sand leakage, the gap of brake holding brake is decreasing, and the running resistance is increasing, which finally affects the state of mixer motor.
Secondly, due to the attraction of armature and overload operation, the silicon rectifier components of the automatic mixer burned under the impact of instantaneous current. Thirdly, the brake clearance of the automatic mixer is large, which leads to the inflexible separation of the brake disc, thus accelerating the wear of the equipment.
In terms of wear failure maintenance, thermal spraying technology should be applied to the wear surface of the equipment for surface wear, and wear-resistant coatings should be made by spraying heat-resistant, corrosion resistant and oxidation resistant coatings, so as to effectively improve the surface wear resistance of the automatic mixer and prevent surface wear problems.
On the other hand, attention should be paid to the wear of the mixing lubricating device. Due to the harsh operating environment of automatic mixer, the impact, vibration, corrosion and other factors during the continuous operation cause severe wear of the mixer vibration bearing, which affects the safe and stable operation to a certain extent.
During maintenance, high-quality vibration bearing shall be selected and matched lubrication device shall be used to reduce the wear of vibration bearing and ensure the performance of mixer. More relevant content will come to our website http://www.sdzkjf.cn Consult!
