More than 50% of unplanned shutdowns of rotating equipment are caused by shaft misalignment. These unplanned outages reduce equipment availability, resulting in higher maintenance costs and lost production. In addition, the shaft misalignment will also increase the vibration and wear of the machine, increase energy consumption, resulting in the failure of bearings, seals and even couplings, and increase the loss of parts.
First, four common vibration causes of equipment failure

When the respective rotations of two axes form the same straight line, it is called (collinearity).
When two axes are not aligned, they are called misaligned.
Three, wrong type offset (parallel) wrong
The general state of Angle misalignment is mixed misalignment (that is, parallel and Angle misalignment exist at the same time).
4. International general alignment tolerance standards
The machine is divided into a reference end and an adjustment end, and the rotation of the reference equipment is used as a reference or reference line. All measurements of the method are made on the shaft and coupling, and are corrected on the footing of the adjustment end.
(1) Ruler - imprecise and inaccurate (2) dial gauge - accurate, but complex and time consuming (3) Laser alignment - very accurate, easy to use, relatively fast, archival results
Six, why do shaft alignment (1) bearing life (2) reduce the shear stress on the coupling to reduce the risk of overheating and damage to the coupling (3) reduce the wear of the seal to reduce the risk of contamination and leakage of lubrication (4) reduce friction (5) reduce noise and vibration (6) machine trouble-free running time, Increased efficiency and production capacity (7) Reduced cost of replacement parts and downtime (8) Reduced energy consumption KM offers high-precision, easy-to-use laser shaft aligners.
