Using Carbon Thrust Bearing in Sub Motor ( G10Z Grade Carbon ) Saves electricity upto 10% Increase Pump efficiency upto 5% Starts & runs the Pump even at low / fluctuating voltage Motor runs ar full RPM Gives upto 10% more output of water in LPM as compared to teflon / fibre Makes pump rotates freely & silently The motor does not get locked even offer prolonged rest Submersible motors are fitted with Hydrodynamic Self Adjusting Tilting Shoe Thrust Bearing to take the axial down thrust from the pump. These are a complex and clever part of a reliable submersible motor and probably not understood very well. Principle The Hydrodynamic Thrust Bearing transmits the rotating shaft's axial thrust load to the frame of the motor which is mechanically supported in the well. The axial Thrust load is transmitted through the bearing on a self renewing film of lubricant which is water in most motors. The pressure in the fluid film supports the load without the thrust disc or pivot shoes making contact. Theory Fluids tend to stick to most surfaces due to viscosity. and in the case of loose segments thrust bearing we rely on the fluid sticking to the surface on the rotating thrust disc. This fluid is then dragged between the thrust bearing disc and the face of the pivot shoe by centrifugal force and forms a wedge shaped film. This wedge shaped film is essential for the successful operation of the thrust bearing. When the bearing is operating correctly there is no contact between the disc and the face of the pivot shoe. The only time there is contact is when the motor is stopping or starting. This means there should be only negligible wear between the faces and no wear while the motor is operating. Surface finish of the carbon thrust bearing disc is machined flat and exactly perpendicular to the shaft with negligible runout on the face. The surface is lapped to give a very smooth flat finish. The surface of the face of the pivot shoes is also ground and lapped to give a very smooth flat finish and in addition the height of each pivot shoe in a set is identical and the base of the pivot leg is spherical so that the pivot shoes are free to pivot and share the load quality Due to mechanical tolerances there will always be some variations in dimensions but in general they are tightly controlled. The Design of the thrust bearing allows the whole thrust bearing assembly to swivel on the thrust button which also allows the pivot shoes to share the load more evenly.
