输送带的这些常识你都是怎么处理的?

1、 输送带接头为什么容易开裂、断开?
1. Why are conveyor belt joints easy to crack and break?
输送带接头处的强度比正常带体的强度要低。一般用机械方式连接时,接头强度仅能达到带体强度的40-50%,冷胶方式质量比较好时,接头强度能达到60-70%,而热胶接头强度能达到80-90%(接头方法正确、无质量缺陷)。由于接头部位的强度比较低,如果胶接方法不正确,接头的强度就会更加低,如开刀,打磨时伤及下一层布、打磨过度、搭接长度不够、台阶个数不够、胶接头所用橡胶性能不好或已经自硫失效、钢丝绳打磨过度、钢丝绳生锈等,接头部委的强度将会大打折扣,在使用时,容易出现开裂(面胶部位)。
The strength of belt joint is lower than that of normal belt. Generally, the joint strength can only reach 40-50% of the belt strength when the mechanical connection is used. When the quality of cold glue is better, the joint strength can reach 60-70%, and the strength of hot glue joint can reach 80-90% (the joint method is correct and there is no quality defect). Because the strength of the joint is relatively low, if the bonding method is not correct, the strength of the joint will be even lower, such as cutting, damaging the next layer of cloth when grinding, excessive grinding, insufficient lap length, insufficient number of steps, poor performance of the rubber used in the rubber joint or self sulfur failure, excessive grinding of wire rope, rust of wire rope, etc. the strength of the joint will be greatly reduced When used, it is easy to crack (glue part).
2、 输送带打滑是由于什么原因?
2. What is the reason for the belt slipping?
输送带正常运转时,带速不低于滚筒转速的95%。如果滚筒与输送带的摩擦力不够,输送带就容易出现打滑现象。引起滚筒与输送带摩擦力不够的原因很多,常见的有:张力不够、载荷启动、滚筒表面摩擦系数不够等。
When the conveyor belt is in normal operation, the belt speed shall not be lower than 95% of the drum speed. If the friction between the roller and the conveyor belt is not enough, the conveyor belt is prone to slip. There are many reasons for insufficient friction between roller and conveyor belt, such as insufficient tension, load starting, insufficient friction coefficient of roller surface, etc.
张力不够的原因有:张紧行程不够、配重重量不够、输送带太长等;
The reasons for insufficient tension are: insufficient tension stroke, insufficient counterweight, too long conveyor belt, etc;

滚筒表面摩擦系数不够的原因有:滚筒表面包胶磨损太大、带体过湿或粘有润滑油、带体表面粘有物料(易被水溶涨的)。
The reasons for the insufficient friction coefficient of the roller surface are: too much rubber coating wear on the roller surface, too wet or sticky with lubricating oil on the belt body, and sticky materials on the belt body surface (easily dissolved by water).
3、 胶接用胶料、胶浆储存有哪些要求?
3. What are the requirements for the storage of adhesive and glue?
胶片、胶浆应保存在阴暗、干燥的地方,避免阳光直接照射、避免各种辐射,并远离火源。
The film and glue should be kept in a dark and dry place to avoid direct sunlight, radiation and fire.
胶片、胶浆应避免保存在灰尘较大的场所,避免各种化学物品与其相接触。
The film and glue should not be stored in the place with large dust and avoid the contact of various chemicals.
保存胶片、胶浆的环境湿度50-75%,温度应不低于5℃,不超过35℃。
The humidity of the environment for storing film and glue should be 50-75%, and the temperature should not be lower than 5 ℃ and not exceed 35 ℃.
胶片、胶浆的保存期:夏季1个月、冬季2个月、春季1个月。
Storage period of film and glue: 1 month in summer, 2 months in winter and 1 month in spring.
