PUMP - MOTOR SHAFT ALIGNMENT PRECEDURE: 

DETAILS STEPS;

• PREPARE THE EQUIPMENT:  Ensure the pump and motor are properly supported and the coupling is accessible, clean the coupling faces and remove any debris .                                 
• CHECK FOR SOFT FOOT: identify and correct any unevenness in the pump or motor base, also known as soft foot, using shins or other methods.                                                                   
• MEASURE ALIGNMENT: Use a chosen alignment method ( e.g dial indicator, laser alignment) to measure the initial misalignment.                                                            
• MAKE ADJUSTMENT: adjust the position of the pump or motor by shinning, involving the motor or using tolerances.                                      
• RE- MEASURE AND VERIFY: after adjustment, remeasure the adjustment to ensure it's within acceptable tolerances.                                            
• SECURE THE COUPLING: Once the alignment is verified, securing tighten the coupling bolts.   
• MAINTENANCE: Regularly monitor the machinery for signs of misalignment, such as increased vibration or noise.                                                                                                                     

METHOD OF MEASUREMENTS

• DIAL INDICATORS:  Are used to measure radial and axial movement of the shafts , requiring mounting on the pump and motor shafts.           
• LASER ALIGNMENT: Laser alignment systems use lasers and sensors to precisely measure alignment, providing guidance on how to relocate and position the motor.                            
• STRAIGHT - EDGE ALIGNMENT                              
• RIM- FACE DIAL INDICATOR ALIGNMENT

IMPORTANT CONSIDERATION DURING PUMP - MOTOR SHAFT ALIGNMENT.                                                 

• Thermal Expansion
• Coupling Type
• Sequence of alignment
• Soft foot : Correct soft foot is a crucial step in the alignment process to ensure proper support of the Pump and Motor.
