1.概述。 我公司研制成功的大电流(4000A～10000A)磁粉探伤设备,一台机通常有16～24个输入输出电接头,以前都是用普通螺栓、螺母、防震圈紧固联接而成的,用户反应在探伤机工作过程中,由于输入输出电流较大,电缆振动比较厉害,时常发生螺栓松动,导致充退磁电流下降,或发生打火损坏接触面等现象,直接影响使用性能,缩短机器寿命。近年来,我们经过实践,采用厌氧胶进行锁固防松,解决这一难题,取得了很大的成功。
1 Overview. My company successfully developed high-current (4000A ~ 10000A) magnetic particle testing equipment, a machine usually has 16 ~ 24 input and output electrical connectors, used to be used in ordinary bolts, nuts, shockproof fastening made of the ring, the user response In the process of flaw detection, due to large input and output current, more severe vibration of the cable, frequent bolt loosening, lead to demagnetization current drop, or sparking damage to the contact surface and other phenomena, directly affect the performance and shorten the life of the machine. In recent years, we have achieved great success by adopting the practice of using anaerobic adhesive for locking and locking to solve this problem.
