自动搅拌车运行的过程当中,受擦伤、侵蚀、冲击、微振以及滑动等因素,容易出现磨损问题,影响到自动搅拌车的电磁制动器稳定运行,甚频繁出现运行故障。
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.
自动搅拌车出现磨损故障的诱因主要包括以下方面。是未能设置封闭外罩,因为自动搅拌车振动,过满、偏装以及沙尘等,导致斗骨料洒漏,水泥以及砂石渗漏到制动器的内部并磨损闸盘。
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.
随着水泥以及砂石渗漏量的持续增加,制动器抱闸的间隙不断减少,运行的阻力日益上升,终影响到搅拌机电机状态。
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.
其次,自动搅拌车硅整流元器件因为衔铁吸引力以及过载运行等问题,在瞬间电流冲击下烧毁元器件。再次,自动搅拌车的制动器间隙较大,导致闸盘分离不够灵活,从而加速设备磨损。
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.
在磨损故障维修方面,方面需要针对表面磨损在设备磨损面应用热喷涂技术,通过喷涂耐热、耐腐蚀以及抗氧化的涂料,来制作得到耐磨涂层,从而有效改善自动搅拌车的表层耐磨性,防止出现表层磨损问题。
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.
另一方面需要重视搅拌的润滑装置磨损问题。因为自动搅拌车运行的环境较为恶劣,在持续运行的过程当中,受冲击、振动以及腐蚀等因素的影响,导致搅拌机振动轴承严重磨损,在一定程度上影响稳定运行。
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!
