圆锥破碎机的常见故障及检修措施

圆锥破碎机容易出现大小圆锥齿轮磨损,断齿;油箱中油量减少,油位显著下降;油流指示器内没有油流,油泵运转,但油压低于 0.05 MPa;油中有水,油箱中油位增高;水封排水中有油,油温未升高;油压升高的同时油温也升高;过滤器前后压差太大;油温超过 60 ?,但油压未升高;润滑油的油质变差;破碎机经常振动;有剧烈冲击声,支承套跳起,然后又正常工作;破碎矿石时有噼裂声音;破碎机有强烈振动、动锥自转很快等故障。这些故障不但影响了破碎机效率的正常发挥,而且使破碎机许多零部件、润滑油的使用寿命大幅度降低,备件、材料消耗明显上升,并增加了维修和生产的劳动强度。因此,合理地处理好这些故障是保证圆锥破碎机正常运转的必要条件。

1常见故障原因分析

1.1 大小圆锥齿轮磨损快,并时常发生断齿

1.1.1 圆锥齿轮的正常啮合条件遭到破坏

圆锥破碎机的传动原理:异步电动机带动与齿轮轴装为一体的小圆锥齿轮,小圆锥齿轮带动与偏心轴套装为一体的大圆锥齿轮,带有锥度并与动锥躯体装为一体的主轴在偏心主轴的驱动下,其轴线以球面轴承的球心为顶点,绕破碎机中心线作锥面运动,从而达到破碎矿石的目的。

圆锥破碎机偏心轴套在旋转过程中因偏心及配重块的强大离心作用,使其厚边总是压在机架衬套上,而薄边与机架衬套始终保持一定间隙,所以大圆锥齿轮在转动过程中不是绕本身的中心线旋转,而是以机架衬套的间隙 a 之半 (a/ 2) 为半径,绕破碎机中心线作圆周运动。

一对圆锥齿轮正常啮合,必须是两齿轮的锥顶交于一点,并且节圆重合。而大圆锥齿轮的这种特殊运转状态破坏了一对圆锥齿轮正常啮合关系,因此运转过程中齿轮的齿面上产生很大的冲击负荷和滑动摩擦。另外,由于圆锥破碎机偏心轴套与机架衬套的间隙大于一般滑动轴承之间的间隙,PY2200 圆锥破碎机此处间隙设计为 4,4.6 mm,运转过程中大小圆锥齿轮的锥顶相距?2,2.3 mm;所以导致大小圆锥齿轮受冲击负荷、磨损或断齿的现象较普遍。特别是小圆锥齿轮,相对于大圆锥齿轮而言,因齿数少,齿的根部薄,断齿更加普遍,

天冷冻不起来的话,可以拉进内部去,缓一缓就能有效果了,因为天冷所以说起不来是正常。

回答(3):

圆锥破碎机天冷启动不了,可以把圆锥破碎机拿到屋里来启动。

回答(4):

圆锥碎冰机,天冷了启动不了,这个时候就要把顺便接用电热烘烤设备烘烤一下。

汽车发动不起来主要原因
原因1、启动时只听到启动机电磁开关“咯咯”声,或首次启动时启动机带动曲轴缓转几下,继而出现启动电磁开关“咯咯”响,但曲轴却不转动。此现象一般属于蓄电池“断格”故障。
原因2、临时停车每次都能启动,但停车时间较长或第二天启动时却只能使曲轴转一下。此现象属于蓄电池自放电严重,其极板、隔板严重老化,说明该蓄电池已经接近报废。
