1、TL钢铝拖链产地:山东恒通http://www.hengtonght.com
2、产品特性:TL系列拖链主体是由链板(优质钢板镀铬)、支撑板(挤拉铝合金)、轴销(合金钢)等部件组成,使电缆或橡胶管与拖链之间不产生相对运动, http://www.ht218.com不产生扭曲变形。TL钢制拖链可适应最大移动速度40米/分,且噪声声压级不大于68分贝。拖链的安全使用寿命不小于100万次(往复)。产品采用高强度耐磨材料,合金铜为轴销,提高了产品的耐磨强度。链板经镀铬处理外形效果新颖,结构合理,不变形,灵巧强度高。弯曲灵活、阻力小、 噪音极小。安装方便、易拆装。http://www.ht612.com
3、产品型号:TL.
TL series steel drag chains
TL series steel drag chains are mainly consisting of chain plate(top quality stainless steel with chromium plated),supporting board (extruded aluminium alloy) and pinshaft(alloy),etc.There is no relative motions between the cables/rubber hoses and the drag chains,giving no deforming or twists.The chromium plated chain board has very nice-looking apearance and has very rational construction and flexible and high strength,It is reliable and easy to operate,install dismantal or assemble.It is worthwhile mentioning that the anti-wearing performance has been improved greatly due to wear resistant material and alloy pinshaft are used.The product is flexible to bending and has low resistance, giving low noises.It can be used for a very long period of time without any deformation or hanging down.
The product is nice-looking.
1.The drag chain can adapt to max.moving speed of 40m/sec.
2.When at the max moving speed,the sound pressure of noises shall not be greater than 68db.
3.The service life of the drag chain shall not be less than 1 million times(reciprocating).
拖链的选用
1.支撑板内腔孔径。,D1=d+≈0.1d(取整数)其中d=电线、电缆、液.气软管的外径。
2.根据支撑板内腔最大孔径Dmax来确定链板高度hg和拖链型号TLXX.
3.根据拖链功能要求来确定支撑板型式的拖链的弯曲半径:
(1)当拖链需承载较大管、缆负荷时,应选用高强度支撑板Ⅰ型(整块式)。
(2)当管缆的管接头尺寸大于支撑板内腔孔径或须经常拆装、维修等时可选用支撑Ⅱ型。属分开式类型支撑板。
(3)安装管缆的规格品种较多时可选用支撑板Ⅲ型(框架式)。
4.根据安装管缆的数量来决定支撑板宽度B1,从而可得拖链宽度B。
5.拖链使用场合或受环境影响时,需要采用钢带防护支撑板时,请与本公司另行提出。
带三条链板的拖链
因为支撑板最大长度为6O0mm∽65Omm .在较宽拖链上可以装置一个或多个拖链链板。另外的原因是可提高料窄的拖链的稳定性,此外也可通过第三条链板将套管与电缆隔开。
注:GLE型取参数D,12,TL型取f,J,k .
液压管的弹性状况
要注意,液压管在压力下会伸长或缩短,因此应考虑到软管的弹性系数.特别是在高压及拖链长度较长的情况下.应引起注意。
