Vibration testing machine operation method and precautions function and characteristics

Operation method and precautions: 1. Determine the power supply and connect the power cable. (Pay attention to the difference between the power supply of the machine, the external incoming power supply of 220V and 380V) 2. The table connecting cable is connected to the corresponding output outlet. (Vertical output or horizontal output, and pay attention to the three-axis switch direction selection) 3. Before starting, fine-tune the amplitude modulation adjustment to "0" position. 4. Press the power switch to ON, that is, turn on the power supply, and the indicator is on. (except 5000Hz) 5. When L type AM output, slowly rotate the amplitude to adjust the twist, so that the table reaches the required amplitude. 6. When the function is output, the amplitude of the output frequency is mainly through the function regulator. At this time, the fine-tuning amplitude-modulation adjustment twist only plays the role of micromotion adjustment. 7, adjust the amplitude should be careful not to exceed the amplitude range of the machine itself, otherwise there will be out of control or abnormal sound, should immediately stop working to correct. 8. After normal operation or regular time operation, the main measured object on the table should be fixed to prevent the loss of the object caused by vibration displacement. 9. The table can not work in the overload or no-load large amplitude state. 10. The control box is a power control component and must not withstand heavy objects and violent vibration. 11. Do not unplug any cable during work. 12. The control box and countertop have heat dissipation holes, and any logistics and debris are not allowed inside. 13. If the noise is found, stop the machine immediately for inspection, or contact the manufacturer to deal with it before continuing operation.

Functions and characteristics:

First, the role of vibration test bench:

1, early screening of defective parts.

2. Strength of structure.

3. Loosening of the bond.

4. Damage of parts.

5, protect the wear of materials.

6, circuit short circuit and intermittent instability.

7, the standard value of each part offset.

8. Poor contact of electronic components.

9, find the resonance relationship between parts, structure, packaging and transportation process.

Two, the advantages of vibration test bench:

1, design, can analyze the damage point, easy to bad points.

2, quality, can analyze the differences and bad points generated by each batch of products.

3, during production, it can be completely measured while vibrating, so that the product defect rate is found early.

4, durability measurement, make the product durable use, make the non-durable components improved early, the company's brand reputation will be better.
