进行破碎机设备三大故障的检修要点是什么?_破碎机厂家


发布时间:2018-11-06 发布人:admin

在冶金、矿山、化工、水泥等工业部门,每年都有大量的原料和再利用的废料都需要用破碎机进行加工处理。如在选矿厂,为使矿石中的有用矿物达到单体分离,就需要用破碎机将原矿破碎到磨矿工艺所要求的粒度。需要用破碎机械将原料破碎到下一步作业要求的粒度。破碎机厂家提醒,在炼焦厂、烧结厂、陶瓷厂、玻璃工业、粉末冶金等部门,须用破碎机械将原料破碎到下一步作业要求的粒度。
In the industrial sectors such as metallurgy, mining, chemical industry and cement, a large number of raw materials and recycled wastes are processed by crushers every year. For example, in a concentrator, in order to separate the useful minerals in the ore into monomers, it is necessary to use a crusher to break the raw ore into the granularity required by the grinding process. The raw material needs to be broken by crushing machinery to the granularity required for the next operation. The crusher manufacturer reminds that in the coking plant, sintering plant, ceramics factory, glass industry, powder metallurgy and other departments, it is necessary to use crushing machinery to crush the raw materials to the granularity required for the next operation.

破碎机厂家认为破碎机三大故障主要分为:轴承故障检修、转轴故障检修和定、转子铁芯故障检修。下面鑫重威矿破碎机厂家就对三大故障检修要点进行一下分析:
The manufacturer of the crusher thinks that the three major faults of the crusher are: bearing fault maintenance, shaft fault maintenance and fixing, rotor core fault maintenance. The following manufacturer of xinzhongwei mine crusher makes an analysis of the three major fault repair points:

一、轴承故障检修磨损的部件
1. Bearing failure maintenance worn parts

转轴通过轴承支撑转动,是负荷最重的部分,又是容易磨损的部件。
The shaft rotates through bearing support, which is the heaviest part of load and easy to wear parts.

1、故障检查
1. Fault inspection

运行中检查;滚动轴承缺油时,会听到“骨碌骨碌”的声音;若听到不连续的“梗梗”的声,可能是轴承钢圈破裂。轴承内混有沙土等杂物或轴承零件有轻度磨损时,会产生轻微的杂音。
In-service inspection; When the rolling bearing is short of oil, it will hear the sound of "toily-bone". If you hear the sound of discontinuous "stem", it may be that the bearing steel ring is broken. When the bearing is mixed with sand and other debris or bearing parts have slight wear, it will produce slight noise.

拆卸后检查;先察看破碎机轴承滚动体、内外钢圈是否有破损、锈蚀、疤痕等,然后用手捏住轴承内圈,并使轴承摆平,另一只手用力推外刚圈,如果轴承良好,外钢圈应转动平稳,转动中无振动和明显的卡滞现象,停转后外钢圈没有倒退现象。否则说明轴承已不能再用了。左手卡住外圈,右手捏住内钢圈,用力向各个方向推动,如果推动时感到很松,就是磨损严重。
Inspection after disassembly; First examined the crusher bearings rolling body, inner and outer steel ring to see if there is any breakage, rust, scar, etc., and then hold bearing inner ring with the hand, and makes the bearing straight, another hand push just outside the circle, if the bearing is good, the outer rims should rotate smoothly, no vibration in rotation and obvious card lag phenomenon, after a halt outside rims no setback. Otherwise, the bearing is no longer usable. The left hand is stuck in the outer ring, and the right hand holds the inner ring and pushes it hard in all directions.

2、故障修理:轴承外表面上的锈斑可用砂纸擦除,然后放入汽油中清洗;或轴承有裂纹、内外圈碎裂或轴承过度磨损时,应更换新轴承。破碎机厂家提醒大家更换新轴承时,要选用与原来型号相同的轴承。
2. Fault repair: the rust stain on the outer surface of the bearing can be wiped off with sandpaper and then cleaned in gasoline. Or when the bearing is cracked, the inner and outer ring is broken or the bearing is excessively worn, the new bearing should be replaced. The crusher manufacturer reminds you to choose the same type of bearing when replacing the new bearing.

二、转轴故障检修
2. Troubleshooting of rotating shaft

1、轴颈磨损;轴颈磨损不大时,可在轴颈上镀一层铬,再磨削至需要尺寸;磨损较多时,可在轴颈上进行堆焊,再到车床上切削磨光;如果轴颈磨损过大时,也在轴颈上车削2-3mm,再车一套筒,趁热套在轴颈上,然后车削到所需尺寸。
1. Journal wear; When the wear of the shaft neck is small, the shaft neck can be plated with chromium and then grinded to the required size. When there is much wear, it can be surfacing welding on the shaft neck and then cutting and polishing on the lathe. If the shaft neck is worn too much, cut 2-3mm on the shaft neck, then turn a set of cylinder, cover the shaft neck as hot as possible, and then cut to the required size.

2、轴弯曲;若破碎机轴弯曲不大,可通过磨光轴颈、滑环的方法进行修复;若弯曲超过0.2mm,可将转轴放于压力机下,在拍弯曲处加压矫正,矫正后的轴表面用车床切削磨光;如果弯曲过大,则需另换新轴。
2. Axial bending; If the crusher shaft bending is not large, it can be repaired by grinding the shaft neck and slip ring. If the bending is more than 0.2mm, the rotating shaft can be placed under the press to be pressurized and corrected at the beat bend. The corrected shaft surface can be machined and polished with a lathe. If the bending is too large, a new axis needs to be replaced.

三、定、转子铁芯故障检修
Iii. Fixed and rotor core fault maintenance

定、转子都是由相互绝缘的硅钢片叠成,是电动机的磁路部分。破碎机厂家根据多年的工作经验认为定、转子铁芯的损坏和变形主要由以下几个方面原因造成。
The stator and rotor are made of mutually insulated silicon steel sheets, which are part of the magnetic circuit of the motor. According to years of working experience, the crusher manufacturer believes that the damage and deion of the rotor core are mainly caused by the following factors.

1、破碎机轴承过度磨损或装配不良,造成定、转子相擦,使铁芯表面损伤,进而造成硅钢片间短路,电动机铁损增加,使电动机温升过高。这时应用细锉等工具去除毛刺,消除硅钢片短接,清理干净后涂上绝缘漆,并加热烘干。
1, crusher bearing excessive wear or bad assembly, cause and rotor rub, make the surface damage of the iron core, and cause a short circuit between silicon steel sheet, motor iron loss increase, make the motor temperature rise too high. At this time, the tool such as fine file is used to remove the burrs, eliminate short silicon steel sheet joints, clean and apply insulating paint, and heat drying.

2、拆除旧绕组时用力过大,使齿槽歪斜和向外张开。此时应用尖嘴钳、木榔头等工具予以修整,使齿槽复位,并在不好复位的有缝隙的硅钢片间加入青壳纸、胶木板等硬质绝缘材料。
2. The old winding is removed with too much force, making the tooth groove crooked and open outwards. At this time, the use of sharp nose pliers, wooden hammer and other tools to repair, so that the tooth groove restoration, and in the bad reduction of the gap between the silicon steel gap between the addition of hard insulation materials such as green shell paper, plastic boards.

3、因受潮等原因造成铁芯表面锈蚀。此时需用砂纸打磨干净,清理后涂上绝缘漆。
3. Corrosion of iron core surface due to damp. At this point needs to be sanded with sandpaper clean, after cleaning the coating insulation paint.

4、围绕组接地产生高热烧毁铁芯槽或齿部。可用凿子或刮刀等工具将熔积物剔除干净,涂上绝缘漆烘干。
4. High heat is generated around the bonding site to burn the core groove or tooth part. Use tools such as chisel or scraper to remove the deposit and apply insulating paint to dry.

5、铁芯与机座间结合松动,可拧紧原有定位螺钉。若定位螺钉失效,可在机座上重钻定位孔并攻丝,旋紧定位螺钉。
