What are the reasons for damage to the chain links in a chain plate conveyor? In practical use, since the link connectors are usually slightly larger than the conveyor chain and experience more severe wear, they become the weak point of the entire conveyor chain. The main forms of damage to it are severe wear, fracture, and separation. The causes of this damage are as follows: ① The chain plate conveyor is subjected to pulsating loads over a long period, leading to fatigue failure; ② The connecting pins or bolts of the chain plate conveyor become loose or fall off, and if not detected and replaced in time, it results in uneven stress on the chain links or their separation; ③ On the vertical links of the chain plate conveyor, wear occurs more severely on one side; if these links are not replaced promptly, fracture is likely to occur; ④ When the chain plate conveyor gets stuck, it generates large dynamic and impact loads, causing sudden fluctuations in the speed of the conveyor chain, which in turn leads to unstable operation of the chain and accelerates the wear or fracture of the chain links; ⑤ Poor manufacturing quality of the chain plate conveyor results in low wear resistance, poor toughness, low hardness, or stress concentration that leads to fatigue cracks, thereby reducing its strength.
