This problem is often used when using a pressure test machine. More problems arise when the service life is too long, so we need not only to maintain and maintain the test machine, but also to know some maintenance knowledge. Deal with faults in a timely manner to avoid delaying our product testing. We have been developing test machines for years and summarizing some of the frequent failures.
Pressure tester:
1. During tensile tests, there are always cracks on both sides of the test article.
2. The test machine scale swing inspection is often unstable.3. The hammer returns abnormally, fast and slow.
The passive needle does not stop well in any position and does not coincide with the main needle.
4. When the load increases, the oil system leaks severely or the pipes break.
5. After the sample ruptures, the pendulum quickly returns to its original impact position, which has an impact on the test bench.
In fact, there are many ways to solve the problem. Everyone has different remedies based on their experience with the machine. Some are simple and complex, but the effect is to adjust the machine to its best condition. Let's give it below
We have some maintenance experience in testing.
When both sides of the sample are broken, it means that the specimen cannot be placed well on the test bench. At this point, we use pliers to adjust the test piece to the center of the test bench. Inaccurate scale.
If some parts of the machine are loose or too tight, the relevant parts can be adjusted. If the test is repeated several times, check whether the joints of the oil system are tightened. If the gasket needs to be replaced, it must be timely.
replace.
If the pipe breaks, check if the joints of the oil system are tightened. If you need to replace the gasket, please replace it in time. The tightening of the pendulum can solve the impact on the test bench due to the rapid return journey.
