目前捻股机和成绳机一般均装设与牵引轮相连的机械计数器,久而久之,由于机械的摩擦和磨损,可靠性和精确性下降,在生产运输皮带时同时穿入多根定尺长度的绳或股,即便其中有一根不符合定尺长度也会引起很大的损失。在伏尔加格勒钢丝钢绳厂曾建议利用大家所知道的磁性方法来确定钢绳的长度,为此目的设计了电子计数器。钢绳一般均用铁磁材料制造,在磁场影响以后,保持着残余的磁化强度,这个残余的磁
At present, both the stranding machine and the rope forming machine are generally equipped with mechanical counters connected with the traction sheave. Over time, due to the friction and wear of the machine, the reliability and the precision are reduced. At the same time, Ropes or strands, even if one of them does not meet the length of the length can also cause great losses. At Volgograd Wire Rope Factory, it was suggested to use the magnetic method known to everyone to determine the length of the rope, for which purpose an electronic counter was designed. Steel ropes are generally made of ferromagnetic materials, the magnetic field to maintain the residual magnetization, the residual magnetism
