2024 03-06Dangers of Water Hammer for a Split Case Centrifugal Pump
Water hammer occurs when there is a sudden power outage or when the valve is closed too quickly. Due to the inertia of the pressure water flow, a water flow shock wave is generated, just like a hammer striking, so it is called water hammer. Water...

2023 12-3110 Possible Causes of a Broken Shaft for a Deep Well Vertical Turbine Pum
1. Run away from BEP: Operating outside of the BEP zone is the most common cause of pump shaft failure. Operation away from the BEP can produce excessive radial forces. Shaft deflection due to radial forces creates bending forces, which will occur twi...

2023 12-13Common Troubleshooting Measures for Axial Split Case Pump
1. Operation Failure Caused by too High Pump Head:
When the design institute selects a water pump, the pump lift is first determined through theoretical calculations, which is often somewhat conservative. As a result, the lift of the newly selected ax... -
2023 11-22Case Analysis of Split Case Circulating Water Pump Displacement and Shaft Broken Accidents
There are six 24-inch split case circulating water pumps in this project, installed in the open air. The pump nameplate parameters are: Q=3000m3/h, H=70m, N=960r/m (actual speed reaches 990r/m) Equipped with motor power 800kW The flanges ...
