损坏的叉车轮胎应该如何处理?

来源:/ 日期:2019-04-24 发布人:admin

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,轮胎径向变形增大,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较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 tire of a 5-ton forklift has a proper tire pressure. When the tire pressure is lower than the standard value, the radial deion of the tire increases and the tire deflects excessively on both sides. Therefore, the crown and the inner pressure on both sides of the earth, the tension on the outer wall of the tire, the tire cord produces greater deion and alternating stress in the body. The forklift will compress regularly and cause fatigue loss of the return line. Bad, make the tire cord layer and increase the relative sliding between the tire and the ground, increase the heat generated by friction, the tire temperature rises sharply, reduce the rubber and cord loose and local layered 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.轮胎体滚动阻力增大,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 tire tread is easy to be embedded in road nails and stones, resulting in mechanical damage. The rolling resistance of tire body increases and fuel consumption increases. Experiments show that when the tire pressure is below 20% to 25%, fuel consumption increases by 20%. When the tire pressure is above the standard value, the fuel consumption increases by 20%. When the tire pressure is above the standard value, the fuel consumption increases by 20%. When the Crown Center is grounded, the contact area between tire and road surface decreases, the load per unit area increases, and the tire center wears.
  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.
  Curtain is overestimated, stress increases spinal cord, spinal cord fatigue process accelerates, causing spinal cord tension, leading to early tire burst, abnormal wear of 5 ton forklift tire in six cases: first, wear on the center of the tire crown; second, abnormal wear on the crown; third, abnormal wear on the inside (or outside) turning wheel tire; fourth, saw-toothed wear on the crown; sixth, abnormal wear on the crown.
  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,轮胎受力较为复杂: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.

  The main manifestations are uneven tread wear, loose rupture of curtain and cord, fetal rupture and so on. When a 5-ton forklift truck is running, the tire forces are more complex: the vertical part reacts vertically, producing tangent lines of longitudinal and transverse forces, which cause tire wear and deion in the direction of global or local relative sliding; the tension and compression it produces 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.
  In this way, the strength will be reduced, the shear stress between the curtain layers will be generated, and 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 and heat generation between the tire and the inner tube may occur, some heat is generated in the air, and the other part accumulates heat, resulting in the decrease of tire temperature, the increase of tire performance, abnormal tire wear and tear, resulting in the loosening of the cord. Broken tire, burst tire and other phenomena.
  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较小,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 5 ton forklift truck. The gap between the valve stem and the valve body is very small, the oil leakage is very small, and the hydraulic cylinder can be reduced or tilted slightly without affecting 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较小,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 path is connected with the return passage or oil spill, and automatically returns to the tank. The main reason is that the distribution valve uses too long or the oil is not clean, which accelerates the wear of the stem and valve body, damages the sealing cover and causes oil leakage. If the stem wears less during repair, it can be polished by chrome plating. If the stem wears seriously, it needs to be replaced.
