During the operation of self loading cement mixer, due to wear, scouring, impact, fretting, sliding and other factors, it is easy to produce wear, which affects the stable and safe operation of electromagnetic brake of self loading cement mixer, and even frequent operation faults. So what is the content of wear failure and maintenance technology of self feeding cement mixer?
The main reasons for the abrasion failure of the mixer truck are: the closed cover is not set, and the bucket aggregate, cement and sand leak into the mixer due to excessive vibration, eccentricity and dust of the self feeding cement mixer truck. Wear of brakes and brake discs.
With the increasing leakage of cement and sand, the holding brake gap decreases and the running resistance increases, which affects the state of mixer motor.
Due to the magnetism of armature and overload operation, the silicon rectifier element of mixing truck burns out under the impact of instantaneous current. The brake clearance of the self feeding cement mixer is large, which makes the brake disc separation inflexible, thus accelerating the wear of the equipment.
In terms of wear fault maintenance, on the one hand, the wear surface of the equipment should be worn by thermal spraying technology. By spraying heat-resistant, corrosion-resistant and anti-oxidation materials, the wear resistance of the surface layer of the concrete mixer can be effectively improved and the surface wear problem can be prevented. On the other hand, attention should be paid to the wear of the stirring lubrication device.
Due to the poor operation environment of the mixer, the vibration bearing of the mixer is seriously worn due to the impact, vibration, corrosion and other factors during continuous operation, which affects the safe and stable operation to a certain extent. In the maintenance process, high-quality vibration bearings shall be selected, and the supporting lubrication device shall be used together with the vibration bearings to reduce the wear of the vibration bearings and ensure the performance of the mixer.
Since the explanation of the wear and failure of the feeding cement mixer and its maintenance technology has been completed, it is necessary to carry out the inspection before use and the maintenance after use. For more information, please visit www.sdzkjf.com Cn for consultation.
