Analysis of Common Malfunctions in Hydraulic Testing Machines

There may be the following faults in the use of hydraulic testing machines. In the future, if there are problems, they should be solved in a timely manner. After understanding these problems, we can learn more about the testing machine in the process of testing materials. To gain a better understanding of the structure and existing issues of the machine itself, in order to obtain more accurate material data.

If the machine experiences system oil leakage or oil pipe rupture when increasing the load. Firstly, it is necessary to inspect the oil system to see if there are any problems at several interfaces, which may be caused by vibration or wear during the operation of the machine. If the oil pipe ruptures, it may be due to some problems that occur during the process of continuously increasing the load. It may be necessary to increase the strength of the oil pipe and check whether the systems in several oil delivery areas are normal, such as whether the position of the oil delivery valve is damaged or blocked, or whether the overflow valve piston is stuck or installed upside down, which may also cause the oil pipe to rupture. If the problem with the machine itself is ruled out, it may be due to the quality of the oil pipe itself, and the oil pipe can be replaced.

In the process of testing the sample, there may be instances where the fracture point does not appear at the ideal midpoint. There are many reasons for this phenomenon, but the most common ones are some problems with the machine itself, such as the fixture not clamping the test material in the middle position, or some issues with the machine's installation not being level. But if the sample breaks during the testing process and the pendulum cone rapidly falls back. Thus causing an impact. The occurrence of this problem may be due to a problem with the buffer. In addition to conventional methods of adjustment, it should also be considered whether it is caused by the machine using too little or too dirty oil.

Regularly summarizing some faults or problems that occur during the use of testing machines and promptly troubleshooting them can greatly avoid the occurrence of incorrect test results. Regularly inspect, calibrate, and maintain the machine itself to maintain its cleanliness and safe route, ensuring that the testing machine is in good working condition during each use!
