損壞的叉車輪胎應該如何處理?

在一定的載荷和行駛條件下,5噸叉車的輪胎有一個適當的輪胎氣壓,當輪胎氣壓低于標準值時,輪胎徑向變形增大,兩側有過度偏轉,所以地球的兩側的胎冠、胎內壓力,在輪胎的外側壁的張力,輪胎簾線在體內產生較大的變形和交變應力.叉車定期壓縮變形,會回速線疲勞損壞,使輪胎的簾布層和增加輪胎與地面之間的相對滑動,摩擦產生的熱量的增加,輪胎溫度急劇上升,減少橡膠和簾線松散和地方分層拉伸強度.

  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 deformation 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 deformation 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.
  當障礙物擊中時就會發生穿刺.胎面壓力不均勻,胎肩部分磨損嚴重,產生"橋效應",胎面呈鋸齒狀或波狀.輪胎胎面容易嵌在路釘和石塊中,造成機械損傷.輪胎體滾動阻力增大,油耗增加.試驗表明,當輪胎壓力低于標準值20%至25%時,燃油消耗量增加20%.當輪胎壓力高于標準值時,胎冠中心接地,輪胎與路面接觸面積減小,單位面積負荷增加,輪胎中心磨損.
  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.
  簾子被高估,應力增加脊髓,脊髓疲勞過程加快,引起脊髓拉伸,導致早期的輪胎爆裂,5噸叉車輪胎的異常磨損六種情況下使用:一是輪胎胎冠中央上磨損;二是冠超常磨損.第三、內(或外)的轉向輪的輪胎是超常磨損;四是胎冠呈鋸齒狀磨損;六是王位的偏磨損.
  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.
  主要表現為胎面不均勻磨損、簾層與簾線松散斷裂、胎兒斷裂等.5噸叉車行駛時,輪胎受力較為復雜:在垂直方向上的部分是垂直的反應,產生縱向和橫向力的切線,在全球或局部相對滑動的方向存在使輪胎,造成胎面磨損和變形;它產生的張力和壓縮在體內,導致材料疲勞.

  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 deformation in the direction of global or local relative sliding; the tension and compression it produces in the body, leading to material fatigue.
  這樣就降低了強度,窗簾層之間產生剪應力,當應力超過簾層與橡膠層之間的吸附力時,簾線就會出現松散的外觀.在輪胎變形時,還可能發生輪胎與內胎之間摩擦生熱,部分熱量在空氣中產生,另一部分熱量積聚,造成輪胎溫度下降,性能增加,輪胎磨損異常,造成簾線松脫、斷胎、爆胎等現象.
  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.
  閥桿兩側各有3個槽,可打開或切斷,改變5噸叉車的工作方式.閥桿與閥體之間的間隙很小,漏油量很小,液壓缸可減少或傾斜較小,不影響工作.
  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.
  如果磨損間隙過大,工作油路中的油與回油通道或溢油相連,并自動返回油箱.主要原因是分配閥使用時間過長或油不干凈,加速了閥桿和閥體的磨損,損壞了密封蓋,造成了漏油.如果閥桿在修理時磨損較小,可以用鍍鉻拋光.如果閥桿磨損嚴重,需要更換.
  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.
