If your component begins to leak after one or two years of normal operation, it could be due to a punctured membrane. Under normal conditions, fluid should not pass through the membrane. Here are several possible reasons for membrane failure:
- End of Mechanical Lifespan: The membrane may have worn out after reaching its mechanical limit of 1,000,000 cycles.
- Excessive High Pressure: Operating under excessively high pressure can damage the membrane.
- Aggressive or Corrosive Fluids: Accelerated wear can occur if the fluid is aggressive or corrosive.
- Metal Particles: Metal particles in the fluid can cause physical damage to the membrane.
This issue is likely due to an incorrectly set hysteresis screw. To correct the commutation, please follow the steps outlined in our guide.
If your electrical flow switch is not commuting, consider the following potential causes and solutions:
- Viscous Fluid: A viscous fluid typically causes early commutation, meaning it occurs at lower flow rates. Try using a larger compensation spring.
- Burnt Sensor: The sensor might have burnt out and become stuck in its last working position, even if no fluid is flowing.
- Low Flow Rate Adjustment: If the switch is adjusted for low flow rates, the shutter may be clogged with dust and dirt. Move the slider to higher flow rates.
- Broken Compensation Spring: A turbulent flow could have broken the compensation spring. Ensure the flow switch operates in a vertical position and that there are no turbulent motions or water hammer effects.
