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 ...
