钢丝绳芯输送带常用表示方法：以ST1000H1000?4.0-6.0-6.0为例：ST1000表示的是强度规格，为1000N/mmH表示的是覆盖胶的性能级别：1000表示的是产品的宽度,单位mm，4.0表示的是钢丝绳的直径，单位mm，6.0-6.0表示的是上下覆盖胶的厚度，单位mm。 整芯输送带的表示方法：一般煤矿用PVC和PVG整芯阻燃输送带用强度级别和输送带宽度来表示。
Common expression of steel wire rope core conveyor belt: st1000h1000? 4.0-6.0-6.0 as an example: st1000 represents the strength specification, 1000N / MMH represents the performance level of the covering glue: 1000 represents the width of the product, in mm, 4.0 represents the diameter of the steel wire rope, in mm, and 6.0-6.0 represents the thickness of the upper and lower covering glue, in mm. Expression method of whole core conveyor belt: PVC and PVG whole core flame retardant conveyor belt for general coal mine is expressed by strength grade and conveyor belt width.
强度级别一般分为：4级、5级、6级、7级、8级、9级、10级、11级和**高到16级输送带，分别对应的强度为680S、800S、1000S、1250S、1400S、1600S、1800S、2000S、2240S、2500S、2800S、3100S和3400S。
The strength grades are generally divided into: Grade 4, grade 5, grade 6, Grade 7, Grade 8, grade 9, grade 10, grade 11 and * * high to grade 16 conveyor belts. The corresponding strength is 680s, 800s, 1000s, 1250s, 1400s, 1600s, 1800s, 2000s, 2240s, 2500s, 2800s, 3100s and 3400s respectively.
橡胶输送带宽度一般为：500mm、650mm、800mm、1000mm、1200mm、1400mm、1600mm、1800mm等。所有的运输带必须接成环形才能实际使用，所以输送带的接头是非常关键的。接头的好坏直接影响着橡胶运输带的使用寿命和输送线能否平稳顺畅地运行。
The width of rubber conveyor belt is generally 500mm, 650mm, 800mm, 1000mm, 1200mm, 1400mm, 1600mm, 1800mm, etc. All conveyor belts must be connected into a ring before they can be actually used, so the joint of conveyor belt is very critical. The quality of the joint directly affects the service life of the rubber conveyor belt and whether the conveyor line can run smoothly.
分层橡胶运输带的接头：可以根据需要采用机械接头、冷粘接头、热硫化接头等接头方法。一般冷粘接头、热硫化接头采取的是阶梯式结构接头。 PVC和PVG整芯阻燃运输带的接头：由于整芯带的结构比较特殊，接头不太容易，所以大多数采用机械接头办法，即皮带扣接头。但是8级以上的输送带，为了保证接头效果，一般还是采用热硫化接头的方法。接头的结构都是指状接头。PVC和PVG整芯阻燃运输带的热硫化接头工艺比较复杂，对设备的要求也比较高。
Joints of layered rubber conveyor belt: mechanical joints, cold adhesive joints, hot vulcanization joints and other joint methods can be adopted as required. Generally, cold bonded joints and hot vulcanized joints adopt stepped structure joints. Joint of PVC and PVG whole core flame retardant conveyor belt: due to the special structure of the whole core belt, the joint is not easy, so most of them adopt mechanical joint method, namely belt buckle joint. However, for conveyor belts above grade 8, in order to ensure the joint effect, the method of thermal vulcanization joint is generally adopted. The structures of joints are finger joints. The hot vulcanization joint process of PVC and PVG whole core flame retardant conveyor belt is relatively complex, and the requirements for equipment are also relatively high.
使用重锤张紧装置的皮带运输机在运输带打滑时可添加配重来解决，添加到运输带不打滑为止。但不应添加过多，以免使皮带承受不必要的过大张力而降低运输带产品使用寿命，使用螺旋张紧或液压张紧的皮带运输机出现打滑时可调整张紧行程来增大张紧力。
When the belt conveyor using the heavy hammer tensioning device slips, the counterweight can be added until the belt does not slip. However, too much should not be added to prevent the belt from bearing unnecessary excessive tension and reducing the service life of the conveyor belt. When the belt conveyor with spiral tension or hydraulic tension slips, the tensioning stroke can be adjusted to increase the tensioning force.
但是，有时张紧行程已不够，橡胶输送带产品出现了性变形，这时可将运输带截去一段重新进行硫化，在使用尼龙输送带或EP输送带时要求张紧行程较长，当行程不够时也可重新硫化或加大张紧行程来解决，运输带上下两侧是相互影响又相互独立的。一般情况，下托辊平行度、辊筒水平度不够均会引起运输带下侧跑偏。
However, sometimes the tensioning stroke is not enough and the rubber conveyor belt products have permanent deformation. At this time, a section of the conveyor belt can be cut off and vulcanized again. When using nylon conveyor belt or EP conveyor belt, the tensioning stroke is required to be long. When the stroke is not enough, it can also be vulcanized again or increased. The upper and lower sides of the conveyor belt affect and are independent of each other. In general, insufficient parallelism of idlers and levelness of rollers will cause the lower side of the conveyor belt to deviate.
下侧跑偏，而上侧正常这种情况基本上是由于清扫装置不良、下托辊粘有物料、配重的辊筒不平行、或配重支架偏斜、下托辊相互不平行所致，具体情况要根据实际情况来调整。一般的讲，下侧跑偏是可以纠正的，可以通过改善清扫装置工作状况、辊筒、托辊上粘有的物料、调整下侧平托辊、下侧V型托辊、或安装下侧调心托辊来达到纠偏的目的。
The lower side deviates, while the upper side is normal. This situation is basically caused by poor cleaning device, materials adhered to the lower idler, non parallel rollers of counterweight, deflection of counterweight support and non parallel lower idler. The specific situation shall be adjusted according to the actual situation. Generally speaking, the lower side deviation can be corrected by improving the working condition of the cleaning device, removing the materials stuck on the roller and idler, adjusting the lower flat idler, lower V-shaped idler, or installing the lower self-aligning idler.
