输送带滚筒规格型号
发布者:lizhongssd 发布时间:2019/1/9

一般来说,输送带越厚,驱动滚筒直径越大。相对较大的滚筒对输送带的维护和耐久性有很大的价值。

Generally speaking, the thicker the conveyor belt, the larger the diameter of the driving drum. Relatively large drums are of great value to the maintenance and durability of conveyor belts.

关于输送带滚筒的尺度,机械设计有专业的设计规范和规范。非专业人员很难核算。这儿咱们供给了一个简略的核算方法,供出售人员现场丈量。

With regard to the scale of conveyor belt drum, there are professional design specifications and specifications in mechanical design. It is difficult for non-professionals to calculate. Here we have provided a brief accounting method for on-site measurement by sales personnel.

滚筒直径d,d=dcd表明织物芯的厚度(织物芯带的厚度)或钢丝绳输送带的钢丝绳直径,单位为mm。C是由各种不同资料的胶带制成,其曲折系数为:棉织物为80,尼龙为90,聚酯为108,钢丝绳芯为145。以多家公司出产的6层EE150胶带为例:D一般为108(EE布的系数应高于一般EP布的系数,此处不作评论)。传动滚筒的最小直径应按以下公式核算:d=d*c=648 mm,即,假如按国家核算。依据国际规范,至少应运用800 mm的滚筒。这儿不引荐运用直径为630mm的滚筒的原因是EE布自身比EP布抗干扰性低。能够看出,关于6层以上的输送带,滚筒直径大于800mm。为了节约本钱,许多中小型客户常常运用直径为500毫米的驱动鼓。因而,在输送带的运用中,因为曲折半径过小而引起的橡胶外表或布层脱层现象常常发作。除传动滚筒外,还需考虑:尾滚筒、张紧滚筒等滚筒的直径可为传动滚筒直径的0.8倍;缓冲滚筒、曲折滚筒等滚筒的直径可为传动滚筒直径的0.6倍。

天津快乐十分走势图 The drum diameter d, d = DCD indicates the thickness of the fabric core (the thickness of the fabric core belt) or the wire rope diameter of the wire rope conveyor belt, in mm. C is made of tape with various materials. Its tortuosity coefficient is 80 for cotton fabric, 90 for nylon, 108 for polyester and 145 for wire rope core. Take the 6-layer EE150 tape produced by several companies as an example: D is generally 108 (the coefficient of EE cloth should be higher than that of EP cloth, and there is no comment here). The minimum diameter of driving drum should be calculated according to the following formula: d=d*c=648 mm, that is, if calculated according to the state. According to international standards, at least 800 mm drum should be used. The reason why the drum with diameter of 630 mm is not recommended here is that the anti-interference ability of EE cloth is lower than that of EP cloth. It can be seen that the diameter of the drum is more than 800mm for conveyor belts with more than six layers. In order to save cost, many small and medium-sized customers often use 500 mm diameter drum drive. Therefore, in the application of conveyor belts, delamination of rubber surface or cloth layer often occurs due to too small zigzag radius. In addition to the driving drum, it should also be considered that the diameter of tail drum, tension drum and other drums can be 0.8 times of the diameter of the driving drum; the diameter of buffer drum, zigzag drum and other drums can be 0.6 times of the diameter of the driving drum.
