Y-502型织物强力试验机是用于试验棉纺和化纤织物断裂强度大小的,并以其测试数据作为划分等级的重要依据。试验机在使用过程中可能会出现一些毛病,如果不及时排除而带病使用,则会影响轻纺产品的质量,造成不应有的损失。现将试验机的常见故障、产生原因及排除方法列于下表,供有关同志在检修试验机时参考。试验机有时还会出现示值前正后负或前负后正且超出士1%允差的现象。造成这种毛病的原因很多,有的属于结构设计问题,有的是 Y-502 fabric strength testing machine is used to test the strength of cotton and chemical fiber fabrics breaking strength, and its test data as an important basis for the classification level. Testing machine in the course of the process may have some problems, if not ruled out in time with the use of disease, it will affect the quality of textile products, resulting in undue losses. Tester now common faults, causes and elimination methods are listed in the following table for the relevant comrades in the maintenance of testing machine reference. Test machine sometimes appear before the value is negative or negative before and after the positive 1% tolerance exceeded 1 phenomenon. There are many reasons for this problem, some are structural design problems, and some are
