液压折弯机故障类别很多，今天我们就简单介绍几种，也是经常会遇到的八大故障。
Hydraulic bending machine fault type many, today we will introduce a few simple, but also often encountered eight faults.
1、液压折弯机每一个故障都应按关联故障或非关联故障分类，关联故障计数，非关联故障如误用故障和从属故障等则不计数。但试验时应作记录。
1 hydraulic bending machine every fault should be classified according to the associated fault or non associated fault, associated fault count, non associated faults such as misuse of the fault and the secondary fault is not counted. But records should be made at the time of the trial.
2、在计算折弯机可靠吐特征量时，只计本质故障。但如果该本质故障引起从属故障，则应按较严重故障判定本质故障的类别。
2 when calculating the reliability of the bending machine, only the essential fault. However, if the nature of the fault caused by the secondary fault, it should be more serious failure to determine the nature of the fault category.
3、对无法判定是本质故障或是从属故障的故障，均计为本质故障。
3 is not able to determine the nature of the fault or the fault of the secondary fault, which is the essential fault.
4、若折弯机有多项功能不能完成或性能指标超i过规定界限，而目不能证明它们是同原因引起的，则每一项均判为折弯机的一个故障。若是由同一原因引起的，则只判折弯机发生一个故障。
4 if the bending machine has a number of functions can not be completed or performance indicators over I over the specified limits, and the project can not prove that they are caused by the same reason, each of which is sentenced to a failure of the bending machine. If it is caused by the same reason, it is only a failure to judge the bending machine.
5、若液压折弯机有一项功能不能完成或性能指标超过规定值，而目它是由多个独立的故障引起，则每一独立的故障均判为折弯机的一个故障。
5 if the hydraulic bending machine has a function can not be completed or performance indicators than the specified value, but it is caused by a number of independent faults, each independent failure is a failure of the bending machine.
6、重复故障的每一次故障，都应计入关联故障。
6 each failure of repeated failures should be included in the associated fault.
7、到达规定寿命期限的零配件的更换及超过规定寿命期限使用的损坏，不计入故障数。
7 to reach the life of the provisions of the replacement of the replacement of parts and more than the life of the use of damage, not included in the number of failures.
8、停机检测或试验中止、结束后的检查中发现的故障，其故障发生时间认为是停机的一瞬间。
8 stop testing or test suspension, after the end of the inspection found that the fault, the fault occurred in time that is the moment of downtime.
