叉车轮胎出现非正常磨损的原因

叉车轮胎对设备而言非常的重要,如果出现了磨损等问题 ,就要及时进行处理,不然很容易就会导致整个设备出现不能使用的情况,下面厂家就来为您讲解下吧。Forklift tires are very important to the equipment. In case of wear and other problems, they should be handled in a timely manner. Otherwise, the entire equipment may easily become unusable. Now, Jinan second-hand forklift manufacturer will explain it to you.叉车轮胎有一个适宜的轮胎气压值 ,当轮胎气压低于标准值行驶时,轮胎径向变形增大,两侧产生过度挠曲 ,以致胎冠两侧接地,胎侧内壁受压,胎侧外壁受拉 ,胎体内帘线产生较大的变形和交变应力。Forklift truck tires have an appropriate tire pressure value. When the tire pressure is lower than the standard value, the radial deformation of the tire increases, causing excessive deflection on both sides, so that the two sides of the tire crown are grounded, the inner wall of the tire side is compressed, the outer wall of the tire side is pulled, and the tire cord in the tire body produces large deformation and alternating stress.周期性的压缩变形,会回速帘线的疲劳损坏,使轮胎的帘布层和轮胎与地面之间相对滑移增大,摩擦产生的热量增多 ,轮胎温度急剧上升,使橡胶的抗拉强度降低,帘线松散和局部脱层 ,遇有障碍受到冲击时就产生爆胎 。Periodic compression deformation will lead to fatigue damage of the return cord, increase the relative slip between the tire s cord layer and the tire and the ground, increase the heat generated by friction, sharply increase the tire temperature, reduce the tensile strength of the rubber, loosen the cord and partially delaminate, and cause tire burst when encountering obstacles and being impacted.胎面的压力不均匀,使胎肩部分磨损严重,产生 桥式效应  ,胎面呈齿状或波浪状。轮胎花纹凹部易嵌入道路的钉子和石块,引起机械损伤。胎体滚动阻力加大,燃料消耗量增加 。Uneven pressure on the tread causes severe wear on the shoulder, resulting in a bridge effect . The tread is dentate or wavy. The concave part of the tire pattern is easy to be embedded into the road nails and stones, causing mechanical damage. The tire rolling resistance increases, and the fuel consumption increases.当轮胎气压高于标准值行驶时 ,使胎冠中接地,轮胎与路面接触面积减小,单位面积上的负荷加大 ,胎冠中部磨损加剧。轮胎的帘线受到过度伸张,胎体帘线应力增大,帘线疲劳过程加快,引起帘线拉断 ,造成轮胎早期爆胎。When the tire pressure is higher than the standard value, the middle of the tire crown will be grounded, the contact area between the tire and the road will be reduced, the load on the unit area will be increased, and the wear in the middle of the tire crown will be increased. The tire cord is overstretched, the tire cord stress increases, and the tire cord fatigue process accelerates, causing the cord to break, resulting in early tire burst.
济南二手叉车在一定的载荷胎压下,车速增加,轮胎的变形频率、胎体的振动及轮胎圆周和侧向的扭曲变形(形成静止波)随之增加 ,单位时间内因摩擦而产生的热量增加,轮胎的工作性能下降,甚至出现帘布层破裂和胎面剥落现象 ,加速轮胎的磨损和破坏 。Under a certain load tire pressure, when the vehicle speed increases, the tire deformation frequency, carcass vibration, and the circumferential and lateral distortion of the tire (forming a static wave) will increase. The heat generated by friction in a unit time will increase, and the working performance of the tire will decline, even the curtain layer will break and the tread will peel off, accelerating tire wear and damage.当轮胎受到油脂 、酸碱物质腐蚀和长时间高温作用时,轮胎的理化性能将发生变化,承载能力大大降低 ,使用中也易爆胎。另外,受油腐蚀过的轮胎会出现封气层块状剥落、胎口出现小面积橡胶脱落,以及胎体帘线与橡胶脱离等现象。由于补片无法与含油橡胶亲和 ,因此即使轮胎的损坏伤口很小,也失去了修补的可能性 。When the tire is corroded by grease, acid and alkali substances and subjected to high temperature for a long time, the physical and chemical properties of the tire will change, the load carrying capacity will be greatly reduced, and the tire is also easy to burst in use. In addition, the tire corroded by oil will suffer from block peeling of air sealing layer, small area rubber falling off at the tire opening, and tire cord separation from the rubber. Because the patch cannot be compatible with the oil filled rubber, even if the damage wound of the tire is small, the possibility of repair is lost.道路条件对轮胎的使用寿命影响也很大,它影响到轮胎与地面的摩擦情况及轮胎受到的动载荷。此外在使用中,如果不注意合理搭配和定期换位而造成轮胎承担负荷不均匀 ,也会加速轮胎磨损。更多事项就来我们网站咨询吧。Road conditions also have a great impact on the service life of the tire, which affects the friction between the tire and the ground and the dynamic load on the tire. In addition, in use, if reasonable collocation and regular rotation are not paid attention to, resulting in uneven load bearing of tires, tire wear will also be accelerated.
