损坏的叉车轮胎应该如何处理?

来源:http://www.jnhgjx.net/ 日期:2021-04-28 发布人:hangong

在一定的载荷和行驶条件下,5吨叉车的轮胎有一个适当的轮胎气压,当轮胎气压低于标准值时,轮胎径向变形加大,两侧有过度偏转,所以地球的两侧的胎冠、胎内压力,在轮胎的外侧壁的张力,轮胎帘线在体内产生大的变形和交变应力.叉车定期压缩变形,会回速线疲劳损坏,使轮胎的帘布层和增加轮胎与地面之间的相对滑动,摩擦产生的热量的增加,轮胎温度急剧上升,减少橡胶和帘线松散和地方分层拉伸强度.

Under certain load and driving conditions, the tires of a 5-ton forklift truck have a proper tire pressure. When the tire pressure is lower than the standard value, the radial deformation of the tire increases, and there is excessive deflection on both sides. Therefore, the crown and inner tire pressure on both sides of the earth, the tension on the outer wall of the tire, and the tire cord produce large deformation and alternating stress in the body, It can make the ply of the tire and increase the relative sliding between the tire and the ground, increase the heat generated by friction, sharply increase the temperature of the tire, and reduce the loose rubber and cord and local delamination tensile strength
当障碍物击中时就会发生穿刺.胎面压力不均匀,胎肩部分磨损严重,产生"桥效应",胎面呈锯齿状或波状.轮胎胎面容易嵌在路钉和石块中,造成机械损伤.轮胎体滚动阻力加大,油耗增加.试验表明,当轮胎压力低于标准值20%至25%时,燃油消耗量增加20%.当轮胎压力高于标准值时,胎冠中 心接地,轮胎与路面接触面积减小,单位面积负荷增加,轮胎中 心磨损.
The results show that when the tire pressure is lower than 20% to 25% of the standard value, the tire tread is easy to be embedded in road nails and stones, causing mechanical damage, When the tire pressure is higher than the standard value, the contact area between the tire and the road decreases, the load per unit area increases, and the tire center is worn
帘子被高估,应力增加脊髓,脊髓疲劳过程加快,引起脊髓拉伸,导致早期的轮胎爆裂,5吨叉车轮胎的异常磨损六种情况下使用:一是轮胎胎冠中央上磨损;二是冠超常磨损.第三、内(或外)的转向轮的轮胎是超常磨损;四是胎冠呈锯齿状磨损;六是王位的偏磨损.
The cord is overestimated, the stress increases, the spinal cord fatigue process speeds up, causing spinal cord stretch, leading to early tire burst, abnormal wear of 5-ton forklift tire. It is used in six situations: first, the central wear of tire crown; Third, the tire of inner (or outer) steering wheel is abnormal wear; Fourth, the crown was serrated; Sixth, the partial attrition of the throne
主要表现为胎面不均匀磨损、帘层与帘线松散断裂、胎儿断裂等.5吨叉车行驶时,轮胎受力为复杂:在垂直方向上的部分是垂直的反应,产生纵向和横向力的切线,在全球或局部相对滑动的方向存在使轮胎,造成胎面磨损和变形;它产生的张力和压缩在体内,导致材料疲劳.
When the 5 ton forklift truck is running, the tire force is complex: the vertical part is a vertical reaction, which produces the tangent line of longitudinal and transverse forces, and the tire is worn and deformed in the global or local relative sliding direction; It produces tension and compression in the body, leading to material fatigue

这样就降低了强度,窗帘层之间产生剪应力,当应力超过帘层与橡胶层之间的吸附力时,帘线就会出现松散的外观.在轮胎变形时,还可能发生轮胎与内胎之间摩擦生热,部分热量在空气中产生,另一部分热量积聚,造成轮胎温度下降,性能增加,轮胎磨损异常,造成帘线松脱、断胎、爆胎等现象.
When the stress exceeds the adsorption force between the curtain layer and the rubber layer, the cord will appear loose appearance. When the tire is deformed, friction heat between the tire and the inner tube may also occur. Part of the heat is generated in the air, and the other part of the heat accumulates, resulting in the decrease of tire temperature, increase of performance, abnormal tire wear, and cord looseness Broken tire, flat tire, etc
阀杆两侧各有3个槽,可打开或切断,改变5吨叉车的工作方式.阀杆与阀体之间的间隙很小,漏油量很小,液压缸可减少或倾斜小,不影响工作.
There are three grooves on both sides of the valve stem, which can be opened or cut off to change the working mode of the 5T forklift. The gap between the valve stem and the valve body is very small, the amount of oil leakage is very small, and the hydraulic cylinder can be reduced or tilted slightly, which does not affect the work
如果磨损间隙过大,工作油路中的油与回油通道或溢油相连,并自动返回油箱.主要原因是分配阀使用时间过长或油不干净,加速了阀杆和阀体的磨损,损坏了密封盖,造成了漏油.如果阀杆在修理时磨损小,可以用镀铬抛光.如果阀杆磨损严重,需要更换.
If the wear clearance is too large, the oil in the working oil circuit is connected with the oil return channel or spilled oil, and automatically returns to the oil tank. The main reason is that the distribution valve has been used for a long time or the oil is not clean, which accelerates the wear of the valve stem and valve body, damages the sealing cover, and causes oil leakage. If the valve stem has little wear during repair, it can be polished with chrome plating. If the valve stem is seriously worn, it needs to be replaced
