Reasons for leakage in the ABB positioner

Thread Content

When in use, ABB positioners sometimes experience leaks, which can affect their performance. What are the reasons for the leakage in that locator? The following is an introduction. The main reasons for leaks in Abb positioners are as follows: 1. Substandard welding: This is usually caused by maintenance work or amateur installation. The welding is poor, which can easily lead to leaks. To avoid these problems, it is necessary to have professionals handle any valve positioner services you may need. 2. Corrosion: The weakening of the metal in the valve actuator due to corrosion can lead to leaks. Although valve positioners are designed to resist rust and other forms of corrosion over many years, they can handle aging systems or systems that do not require regular maintenance. Sometimes the corroded parts can be replaced, but when the valve positioner is very old, it is usually better to replace the entire unit. 3. High water pressure: Since the expansion tank can buffer the increased pressure, the pressure inside the valve positioner tank should remain stable. However, conditions such as scale and excessive sediment in the water tank can cause the water pressure to rise. One of the effects of this is the emergence of leaks at the connection points. 　　The above has explained the reasons for leaks inABB positioners. When using it, everyone should try to avoid such situations, as they can affect the operation of the locator.
