The spring tension and compression testing machine is mainly used to test the performance of springs. Although the use of springs is large, due to the influence of volume and use position, it is easy to ignore some matters when using the spring tension and compression testing machine. Therefore If the spring performance is unqualified, it will lead to abnormal operation of the machine, and may even cause accidents, so the spring testing machine is also indispensable.
Daily maintenance and inspection of spring tension and compression testing machine:
1. Basic inspection: the environmental conditions of the flexural modulus testing machine, power supply voltage, power-on self-test, and grounding of the host.
2. Control panel inspection: panel display function, panel button function.
3. Crossbeam operation inspection: whether each speed is running smoothly, whether each speed is running normally, running distance, whether it is overshoot, belt and tension.
4. Lubrication of spring tension and compression testing machine frame: cleaning and refueling.
5. Check the load system: calibration and zero reset of the sensor: measure the standard weight.
6. Strain system inspection: calibration and zero reset of the extensometer: measure the standard length.
7. Transmission system inspection: motor brushes.
8. Safety inspection: mechanical limit, emergency stop switch.
9. Check the accessories of the spring tension and compression testing machine, such as pneumatic clamps, air compression pumps, foot switches, etc.
9 things to pay attention to for spring tension and compression testing machine:
1. The displacement sensor is a precise optical, mechanical and electrical measuring device, which cannot be disassembled or impacted at will.
2. The internal memory can store the data of 40 samples at most. When the number exceeds this number, it will be automatically overwritten and stored from 1. If you need to save the function that will be overwritten, please use the "Query/Print" button in advance to save the data. This content is printed.
3. If there is abnormal sound during the operation of the testing machine, stop the machine immediately and check the lubricating parts.
4. After the test machine is used, it should be covered with machine clothes to prevent dust from falling into the machine.
5. In order to protect personal safety, the testing machine should be properly grounded.
6. Under normal use conditions, the spring testing machine is valid for one verification of its indication error once.
7. When the spring testing machine is in operation, especially when unloading, do not let go of it suddenly, so as to avoid severe vibration and affect the accuracy of the testing machine.
8. Lubricating oil should be frequently added to the lifting rack of the testing machine and each pressure injection oil cup.
9. After the test machine is used, it should be covered with machine clothes to prevent dust from falling into the machine.
