Do you Know the Composition and Structure of the Vertical Turbine Pump and Installation Instructions?
Due to its special structure, the vertical turbine pump is suitable for deep well water intake. It is widely used in domestic and production water supply systems, buildings, and municipal water supply and drainage projects. It has the characteristics of s...
Split Case Pump Vibration, Operation, Reliability and Maintenance
The rotating shaft (or rotor) generates vibrations that are transmitted to thesplit casepump and then to surrounding equipment, piping and facilities. Vibration amplitude generally varies with rotor/shaft rotational speed. At the critical speed, the vibra...
Experience: Repair of Split Case Pump Corrosion and Erosion Damage
Experience: Repair ofSplit Case Pump Corrosion and Erosion Damage
For some applications, corrosion and/or erosion damage is unavoidable. Whensplit casepumps receive repairs and are badly damaged, they may look like scrap metal, but wit...
About the Balance Hole of the Split Case Pump Impeller
The balance hole (return port) is mainly to balance the axial force generated when the impeller is working, and reduce the wear of the bearing end surface and the wear of the thrust plate. When the impeller rotates, the liquid filled in the impeller will ...
30 Reasons Why Bearings of Split Case Pump Make Noise. How Many Do You Know?
Summary of 30 reasons for bearing noise: 1. There are impurities in the oil; 2. Insufficient lubrication (oil level is too low, improper storage causes oil or grease to leak through the seal); 3. The clearance of the bearing is too small ...
