Answer: When the servo cylinder diaphragm leaks, the leakage pressure of the working air source of the servo cylinder is reduced. If it is lower than the spring tension of the servo cylinder, the servo cylinder cannot be opened. At this time, if you observe carefully, you can find that there is continuous or intermittent air coming out of the servo cylinder valve stem. Replacing the servo cylinder diaphragm can eliminate the fault.
To extend the service life of the servo cylinder diaphragm, avoid frequent starting and stopping of the air compressor and frequent loading and unloading adjustments of the air compressor.
