In the current industry development process, spring testing machines have not only improved their functions, but also their types and application fields, and the demand for society is also increasing. Spring fatigue testing machines are one of many types, mainly suitable for testing various air springs and shock-absorbing spring products used in automobile and motorcycle locks for fatigue testing. No matter which machine is used for a long time, some failures will occur, and the spring fatigue tester is no exception. Spring fatigue test opportunities occur when there is a fault, so it is right to do so.
Fault 1: The pressure cannot be increased during use
1. This kind of fault is common in the inspection. The reason for the inability to rise in pressure is usually because there are impurities in the spring fatigue tester when refueling. After the impurities enter the oil cylinder, it will cause the surface of the oil cylinder and the oil plug to wear, and when the gap increases or the processing accuracy becomes worse, oil leakage will occur. At this time, try to use oil with relatively high viscosity. If the pressure still drops due to oil leakage, it is recommended to replace a new oil cylinder.
2. If the spring fatigue test machine is not used for a long time, the leather ring in the oil cylinder will not work if it is dry, which will also cause the pressure to not rise. To solve this problem, the leather ring needs to be soaked for a period of time or replaced.
3. The safety adjustment is not correct. When the instrument oil pumps the oil valve, if the pointer rises smoothly to the high tonnage when the low tonnage occurs, the pointer will always stop in a small range. No matter how the oil inlet is increased, the tonnage will still rise. At this time, you need to loosen the nut of the fuse valve, tighten the screws to the appropriate level, and adjust the nuts, because the fuse valve is a device that ensures that the instrument is not damaged in unexpected situations.
Fault 2: When the force measuring pointer is loaded evenly, it will vibrate or stagnate.
After the spring fatigue tester is installed, if the oil is first injected into the force test cylinder, there will be air inside. If it is not removed in time, it will not only affect the degree, but also cause the pointer to vibrate, so the air must be emptied.
If the oil cylinder is too dirty, it will also cause the pointer to vibrate. When using it, please pay attention to cleaning the oil cylinder regularly. After cleaning, tighten the nut and turn on the machine. When the oil in the oil cylinder flows out, install the piston.
The above is the relevant content that the spring fatigue test opportunity encounters a fault, and this is done correctly. When you encounter the above phenomena when using it, it can help you eliminate them in time to avoid errors in the test results. When using a spring fatigue testing machine, it is important to maintain the spring fatigue testing machine daily. Only when the maintenance is in place can the machine work better, thus making greater contributions to saving production costs and improving corporate profit margins.
