如果粉碎机坏了自己能修理吗?

破碎机设备三大毛病:轴承毛病检修、转轴毛病检修和定、转子铁芯毛病检修。下面就对三大毛病检修要点停止一下剖析。
There are three major faults in crusher equipment: bearing faults, shaft faults and fixing, and rotor core faults. Next, I will analyze the main points of the three major defects.
一、轴承毛病检修磨损的部件
I. Bearing faults, repair and wear parts
转轴经过轴承支撑转动,是负荷最重的局部,又是容易磨损的部件。
Rotary shaft rotates through bearing support, which is the heaviest part of load and easy to wear and tear.
①毛病检查
(1) Examination of faults
运转中检查;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,可能是轴承钢圈决裂。轴承内混有沙土等杂物或轴承零件有轻度磨损时,会产生细微的杂音。
Inspection in operation; when the rolling bearing is short of oil, it will hear the sound of "bone and bone". If it hears the sound of discontinuous "stalk", it may be that the bearing ring is cracked. When the bearing is mixed with sand and other impurities or the bearing parts are slightly worn, a slight noise will occur.
拆卸后检查;先观察破碎机轴承滚动体、内外钢圈能否有破损、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,假如轴承良好,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。否则阐明轴承已不能再用了。左手卡住外圈,右手捏住内钢圈,用力向各个方向推进,假如推进时感到很松,就是磨损严重。
After disassembly, check; first observe whether the crusher bearing rollers, inner and outer steel rings can be damaged, rusted, scarred, and so on, and then pinch the inner ring of the bearing with hand, and make the bearing level, the other hand force out the rigid ring, if the bearing is good, the outer steel ring should rotate smoothly, no vibration and obvious sticking phenomenon in rotation, after stopping rotation, the outer ring does not retrogress. Otherwise, it is stated that bearings can no longer be used. The left hand holds the outer ring, the right hand holds the inner ring, and pushes hard in all directions. If it feels loose when pushing, it will be worn seriously.
②毛病修理
(2) Troubleshooting
轴承表面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,应改换新轴承。改换新轴承时,要选用与原来型号相同的轴承。
The rust spots on the surface of bearings can be erased by sandpaper and then cleaned by gasoline. When the bearings have cracks, inner and outer rings are broken or the bearings are over-worn, new bearings should be replaced. When replacing new bearings, the bearings of the same type as the original ones should be selected.
二、转轴毛病检修
II. Inspection and Repair of Rotary Shaft Faults
①轴颈磨损;轴颈磨损不大时,可在轴颈上镀一层铬,再磨削至需求尺寸;磨损较多时,可在轴颈上停止堆焊,再到车床上切削磨光;假如轴颈磨损过大时,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。
中药超细粉碎机
(1) Journal wear; when journal wear is small, a layer of chromium can be plated on the journal, and then grinded to the required size; when wear is more, surfacing can be stopped on the journal, and then grinded on the lathe; if journal wear is too large, also turning 2-3 mm on the journal, then turning a set of cylinders, while hot sleeve on the journal, and then turning to the required size.
②轴弯曲;若破碎机轴弯曲不大,可经过磨光轴颈、滑环的办法停止修复;若弯曲超越0.2mm,可将转轴放于压力机下,在拍弯曲处加压矫正,矫正后的轴外表用车床切削磨光;假如弯曲过大,则需另换新轴。
(2) Shaft bending; if the bending of the crusher shaft is not large, it can be repaired by polishing the journal and sliding ring; if the bending exceeds 0.2mm, the rotating shaft can be placed under the press, and the bending position can be adjusted under pressure, and the corrected surface of the shaft can be machined and polished by a lathe; if the bending is too large, a new shaft needs to be replaced.
三、定、转子铁芯毛病检修
3. Inspection and repair of stator and rotor core defects
定、转子都是由互相绝缘的硅钢片叠成,是电动机的磁路局部。定、转子铁芯的损坏和变形主要由以下几个方面缘由形成。
The stator and rotor are made up of insulated silicon steel sheets, which are part of the magnetic circuit of the motor. The damage and deformation of stator and rotor cores are mainly caused by the following reasons.
①破碎机轴承过度磨损或装配不良,形成定、转子相擦,使铁芯外表损伤,进而形成硅钢片间短路,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,消弭硅钢片短接,清算洁净后涂上绝缘漆,并加热烘干。
The excessive wear or poor assembly of crusher bearings results in friction between stator and rotor, which damages the appearance of iron core, and then leads to short circuit between silicon steel sheets, which increases the iron loss of motor and makes the temperature rise of motor too high. At this time, the use of fine files and other tools to remove burrs, eliminate short joints of silicon steel sheets, clean up after the application of insulating paint, and heating and drying.
②撤除旧绕组时用力过大,使盗槽倾斜和向外张开。此时应用尖嘴钳、木榔头号工具予以修整,使齿糟复位,并在不好复位的有缝隙的硅钢片间参加青壳纸、胶木板等硬质绝缘资料。
(2) When removing the old windings, too much force is exerted to tilt and open the stolen slot outwards. At this time, the tip tongs and the number one tool of wood hammer are used to trim the teeth to reset the defect, and the hard insulation materials such as Green-shell paper and gluewood board are taken into account among the slit silicon steel sheets which are not easy to reset.
③因受潮等缘由形成铁芯外表锈蚀。此时需用砂纸打磨洁净,清算后涂上绝缘漆。
(3) The outer rust of iron core is formed due to dampness and other reasons. At this time, sandpaper should be used to polish and clean, and insulating paint should be applied after liquidation.
④盘绕组接地产生高热烧毁铁芯糟或齿部。可用凿子或刮刀等工具将熔积物剔除洁净,涂上绝缘漆烘干。
(4) Grounding of coil winding produces high heat to burn iron core grains or teeth. Can use chisel or scraper and other tools to remove the deposits clean, coated with insulating paint to dry.
⑤铁芯与机座间分离松动,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。
_The separation between the iron core and the machine base is loose, and the original positioning screw can be tightened. If the positioning screw fails, the positioning hole can be re-drilled and tapped on the machine base, and the positioning screw can be tightened.
