Centrifugal Pump Failures

Centrifugal Pump Failures
It is possible to group the faults that occur in the pumps in different ways. These malfunctions can sometimes be mechanical, sometimes fluid-related and sometimes electrical faults. Mechanical failures usually occur in stationary or mobile equipment of the pump. It can be caused by external factors as well as material fatigue or a problem that is not resolved in a timely manner. Centrifugal pump failures may be due to fluid problems. These fluid problems can be listed as follows;
• Pump air not taken
• Pump air not taken
• Pump speed is too low
• Pump performance selection or operating error
• Not paying attention to the suction depth and this depth being more than the pump design
• The fan control is not done and as a result the fan is clogged with dirt or other reasons. This blockage is also usually caused by foreign matter. Especially in new plants, it can be a problem caused by not cleaning the piping system thoroughly. Before connecting to the in-plant pump, it must be cleaned of slag, burrs and foreign materials.
• Improper mounting of the fan
• Likewise, some mistakes made in pump assembly; eg incorrect positioning of the pump rotation direction
• Presence of a hole or leak or leak in the pump. Damage to the pump due to lack of maintenance
• Trouble due to coupling alignment
• Problems caused by the suction filter. Debris, debris or some x-items can clog the suction strainers. (Clogging of the strainer used in the suction line)
• Similarly, air may have leaked into the suction pipe. (Plumbing related problems)
