Fault Treatment in Calibration and Use of Old-Fashioned Hydraulic Material Testing Machine
During the calibration and use of the old-fashioned material testing machine,it will encounter some problems,such as loading not reaching the maximum range of the force value,pointer movement during loading,overall vibration of testing machine,abnormal temperature of oil pump,noise exceeding specification requirements and so on.The possible failure causes are analyzed from the oil pump,motor,valve,oil circuit,pressure load and various parts,and the corresponding solutions are given.It provides technical support for the future verification and use of the testing machine.
