How To Disconnect THOMAS Coupling From Induction Motor Hub?

Hi,

This post I would like to share video how to disconnect or dis-engage THOMAS Coupling from motor hub during maintenance works.In this video,technician plan to replace new bearing for the motor due to abnormal sound detected from bearing.Normally in industry or chemical plant,Thomas Coupling is the one of common application to connect electric motor as a drive and pump as a rotary equipment for the process.

The main reason why Thomas coupling are used :-

  1. To transmit power from one shaft to another, efficiently and effectively.
  2. To accommodate slight shaft misalignment which develop in service.

Thomas coupling application also can protect our equipment from mechanical damage and misalignment. Below several protection when using Thomas coupling :-

1. Absorb shock, vibration and pulsations.

2. Decrease cross load on bearings.

3. Accept load reversals.

4. Minimize backlash. Read More

How to install water pump completed with alignment?

On my last post,i already showed my video about how to install soft gland packing seal for water pump.This time i want share some information on my video how to install water pump complete with alignment.

This is common technique for maintenance person to install back the water pump to electric motor.To operated water pump,we need connected with electric motor using coupling.But it is not easy as we thinks if not do it with the correct technique.

If motor coupling and water pump not parallel to each other or not in correct alignment,it can cause bearing damage and more serious it can cause motor winding defect or water pump impeller jammed. read more
