What is the cause of centrifugal pump bearing fever? How to exclude?

cause of issue:
(1) Sliding bearing bush scraping does not meet the requirements.
(2) bearing clearance is too small.
(3) two improper lubricants (too much or too little) or deterioration.
(4) bearing equipment is not correct.
(5) Insufficient cooling water or interruption.
(6) bearing wear or loose.
(7) shaft bending.
(8) oil ring deformation, rotation is not working or can not rotate, with no oil.
(9) Shaft and motor shaft are not concentric.
(10) bushings Babbitt off.

Method of exclusion:
(1) re-scratch the bearing, is 3-5 points per square centimeter, the contact surface of 70 /% or more, a good tank.
(2) re-adjust the bearing clearance or scratch research.
(3) adjust the oil volume, two-thirds of the volume.
(4) Check the bearing assembly as required to eliminate unmet requirements.
(5) Check and clean the cooling water pipe to give enough cooling water.
(6) Check the bearing, adjust the gland, the Department will wear the latest scratch scraping and adjust the gap.
(7) Check, straighten or replace the pump shaft, so that the maximum curvature of less than 0.03mm.
(8) Check the ovality of the oil ring, correct or replace the new oil ring.
(9) Measurement and adjustment of centrifugal pump unit concentricity, so as to achieve the standard requirements.
(10) selected standard Babbitt, re-hang tile, processing. Scraping bearings.

Magnetic Lifter

Magnetic lifter

Introduction:

Magnetic Lifters have strong magnetic path made by strong NdFeB magnetic material which supply permanent power. Our permanent magnetic lifters are made use of in a variety of industries. Our permanent magnetic lifters can hoist iron, steel blocks, cylinder and others and provide a quick and convenient method of loading, unloading, and moving. Our permanent magnetic lifters are the most ideal lifting equipment for factories, warehouses, docks and transportation.

Manual Magnetic Lifter Features:

• Use to lift and transport steel and iron for factories, docks, warehouses, transportation and more.

• Turning the manual handle activates or turns off the magnet.

• Strong attraction gives this tool a powerful lifting ability while it`s small size and light weight makes it easy and safe to operate. Effective for long periods with no need for a power supply.

• The safe coefficient of magnet lifter is 3.5.
