Problems solved by technology

[0002] The crystallizer vibration servo cylinder of continuous casting machine is one of the most critical components in the crystallizer vibration device. The vibration accuracy is very strict. This requires that the vibration servo cylinder used on-line must have good performance. If the servo cylinder is worn or the seal is damaged, There will be internal leakage, the vibration synchronization error of the servo cylinder will exceed the standard, and the production will not be able to run normally
In the production process, because the internal leakage of the servo cylinder was not detected in advance, no vibration or abnormal vibration occurred many times after online use, resulting in forced shutdown. Therefore, the long-term use of the servo cylinder must be tested for internal leakage before it can be used online to avoid After going online, there is a downtime accident
[0003] At present, there are mainly two detection methods for vibration servo cylinders of continuous casting machines in China: (1) Simply disassemble the two-cavity pipeline of the servo cylinder to visually detect the degree of internal leakage. For vibration servo cylinders that require high precision, this detection method is more accurate Poor; (2) Although the large-scale servo cylinder internal leakage detection platform has more complete functions and higher accuracy, it is more expensive, larger in size, and more complicated in operation
