洗沙機在使用過程中常軸承故障檢修:

轉軸通過軸承支撐轉動,是負荷重的部分,又是容易磨損的部件。

①故障檢查--運行中檢查 :滾動軸承缺油時,會聽到“骨碌骨碌”的聲音;若聽到不連續的“梗?!钡穆?,可能是軸承鋼圈破裂。軸承內混有沙土等雜物或軸承零件有輕度磨損時,會產生輕微的雜音。拆卸后檢查:先察看軸承滾動體、內外鋼圈是否有破損、銹蝕、疤痕等,然后用手捏住軸承內圈,并使軸承擺平,另一只手用力推外剛圈,如果軸承良好,外鋼圈應轉動平穩,轉動中無振動和明顯的卡滯現象,停轉后外鋼圈沒有倒退現象。否則說明軸承已不能再用了。左手卡住外圈,右手捏住內鋼圈,用力向各個方向推動,如果推動時感到很松,就是磨損嚴重。

②故障修理:軸承外表面上的銹斑可用00號砂紙擦除,然后放入汽油中清洗;或軸承有裂紋、內外圈碎裂或軸承過度磨損時,應更換新軸承。更換新軸承時,要選用與原來型號相同的軸承。

三、洗砂機轉軸故障檢修

①軸彎曲 :若彎曲不大,可通過磨光軸頸、滑環的方法進行修復;若彎曲超過0.2mm,可將轉軸放于壓力機下,在拍彎曲處加壓矯正,矯正后的軸表面用車床切削磨光;如果彎曲過大,則需另換新軸。

②軸頸磨損:軸頸磨損不大時,可在軸頸上鍍一層鉻,再磨削至需要尺寸;磨損較多時,可在軸頸上進行堆焊,再到車床上切削磨光;如果軸頸磨損過大時,也在軸頸上車削2-3mm,再車一套筒,趁熱套在軸頸上,然后車削到所需尺寸。

During the operation of the sand washing machine, the failure maintenance of the common bearing is as follows:
The shaft is supported by the bearing to rotate, which is the heaviest part of the load, and is easy to wear.
① fault inspection - Inspection during operation: when the rolling bearing is short of oil, the sound of "bone and bone" will be heard; if the sound of discontinuous "stem" is heard, the bearing steel ring may be broken. There will be slight noise when sand and other sundries are mixed in the bearing or the bearing parts are slightly worn. Inspection after disassembly: first check whether the bearing rolling body and the inner and outer steel rings are damaged, rusted, scarred, etc., then hold the inner ring of the bearing by hand, and make the bearing level, and push the outer rigid ring by the other hand. If the bearing is good, the outer steel ring shall rotate smoothly, without vibration and obvious stagnation during the rotation, and the outer steel ring shall not reverse after the rotation s. Otherwise, the bearing can no longer be used. The left hand catches the outer ring, the right hand holds the inner steel ring, and pushes hard in all directions. If you feel loose when pushing, you will suffer serious wear.
② fault repair: the rust spots on the outer surface of the bearing can be wiped off with No.00 sandpaper, and then cleaned in gasoline; or if the bearing has cracks, the inner and outer rings are broken or the bearing is excessively worn, the bearing shall be replaced with a new one. When replacing a new bearing, select the same bearing as the original model.
III. troubleshooting of rotating shaft of sand washing machine
① shaft bending: if the bending is not large, it can be repaired by polishing the journal and slip ring; if the bending is more than 0.2mm, the rotating shaft can be placed under the press, and the bending part can be pressurized and corrected, and the corrected shaft surface can be cut and polished by lathe; if the bending is too large, it needs to be replaced with a new shaft.
② journal wear: when the journal wear is not large, a layer of chromium can be plated on the journal, and then ground to the required size; when there is more wear, overlaying welding can be carried out on the journal, and then cutting and polishing can be carried out on the lathe; if the journal wear is too large, 2-3mm can also be cut on the journal, and then a sleeve can be turned to cover the journal while it is hot, and then turning to the required size.
