1. Improper installation length of conveyor belt

无论是新带安装还是旧带更换，如果事前没有对整条输送带的安装进行仔细的规划计算，就很容易造成输送带接长了的情况，直接后果是配重（重锤式配重）撞击地面，导致起动打滑。有的虽然当时没有问题，试车也没有问题，但是配置位置较低，运转两三个月后，配重下垂，起动时撞击地面。这是因为安装过程中没有考虑到输送带的塑性变形和弹性变形。

Whether it is the installation of new belt or the replacement of old belt, if the installation of the whole conveyor belt is not carefully planned and calculated in advance, it is easy to cause the conveyor belt lengthening, and the direct consequence is that the counterweight (heavy hammer counterweight) hits the ground, resulting in starting slip. Although there were no problems at that time and during the test run, the configuration position was low. After two or three months of operation, the counterweight sagged and hit the ground when starting. This is because the plastic deformation and elastic deformation of the conveyor belt are not considered in the installation process.

输送带安装时也不宜太短，应为以后的维护留有一定的余量。如果长度基本在螺旋张紧的更小处。使用一段时间后接头出现问题，输送带余量不够，无法重做接头，只好重新安装新带。这样使我们的输送带造成了白白的浪费。同时使企业受到一定的不必要损失。这是我们生产中不想看到的情况。

Conveyor belt installation should not be too short, should be left for future maintenance of a certain margin. If the length is basically at the minimum of screw tension. After using for a period of time, there was a problem with the joint, and the belt allowance was not enough to make the joint again, so a new belt had to be installed. This makes our conveyor belt waste. At the same time, the enterprise suffered some unnecessary losses. This is something we don't want to see in production.

理想的输送带安装情况是，输送带安装后长度适中(我们应考虑到夏，冬两季温度对输送带膨胀率影响的差别)，更好能够预留一个接头的余量。

The ideal installation situation of conveyor belt is that the length of conveyor belt after installation is moderate (we should consider the difference of the influence of temperature on the expansion rate of conveyor belt in summer and winter), and it is better to reserve a joint margin.

2接头质量不过关

2. The quality of the joint is not up to standard

输送带的接头胶接监理是输送带安装过程中更重要的一环。接头质量的好坏，直接影响到输送机能否正常运行。因硫化接头质量问题造成的断带事故时有发生，不仅影响生产，有的还造成人身伤害。接头质量的好坏反映在使用效果上，如果胶接过程中不加强临控，仅靠完工验收是难以看出问题的，所以，严把硫化接头质量关在输送带安装过程中成为重要。

The supervision of belt joint bonding is the most important part in the process of belt installation. The quality of the joint directly affects the normal operation of the conveyor. The belt breaking accidents caused by the quality problems of vulcanized joints occur from time to time, which not only affect the production, but also cause personal injury. The quality of the joint is reflected in the use effect. If the temporary control is not strengthened in the bonding process, it is difficult to see the problem only by the completion acceptance. Therefore, it is important to strictly control the quality of the vulcanized joint in the installation process of the conveyor belt.

3安装完成后没有进行试车调整

3. There is no commissioning adjustment after installation

没有经过运转磨合时，新安装的输送带极易发生局部磨损的现象。要特别重视漏斗调料板，裙板，挡料板等啊件的调整。防止输送带跑偏，卡料等现象的发生。此外，还要加强对输送带运转过程的监护，防止卡住大块物料致使输送带过度磨损。

Without running in, the newly installed conveyor belt is prone to local wear. Special attention should be paid to the adjustment of hopper, seasoning plate, skirt plate, baffle plate, etc. Prevent the conveyor belt deviation, jam and other phenomena. In addition, it is necessary to strengthen the monitoring of the running process of the conveyor belt to prevent the conveyor belt from being excessively worn due to the blocking of large materials.
