(1) Failure during debugging
The fault problem of the electric actuator of the regulating valve is more complicated. It is characterized by many problems such as design, manufacture, installation and management. Action failure. Some components are missing or incorrectly installed with springs and seals. Some are due to improper design, improper component selection, unstable movements, poor positioning accuracy, etc. To deal with such failures, you should be patient and careful, and deal with them carefully, and eliminate them one by one.
(2) Early and mid-term failures
The fault characteristic that enters the normal production stage after commissioning is that a small number of seals are damaged in a short period of time due to assembly quality and material quality problems, and oil leaks. These components are unstable, usually in the middle of the journey, the system components/components are in the best operating state, and the failure rate is low.
