Double clip pneumatic ball valve with and without feedback, is port 2 open or closed? What are the causes of pump vibration
1. The manufacturing process of the water pump is not up to standard: the rotor is unbalanced; The pump and motor shafts are not concentric; Collision or friction between rotor and stator;
2. Due to long service time, the water pump is worn and aged: the impeller is loose; Bearing damage or large bearing clearance;
3. There are sundries in the water pump inlet pipe, impeller and pump; The water pump is not fixed firmly with the foundation, and resonance strengthening phenomenon occurs;
4. When the water pump is working to promote the water flow, the accompanying vortex and cavitation will inevitably produce vibration
