Shaft alignment handbook pdf

The purpose of producing this handbook is to provide basic information and guidelines for the implementation of good shaft alignment for. Laser alignment is an essential component of a viable maintenance. Turn on the XA to allow it to boot up. Mount the ‘S’ sensor on the stationary shaft.

The sensors may be mounted on the shafts or on the coupling hubs. Place the bracket on the shaft and pull the chain under the shaft and hook it over the pin. The state of shaft alignment is traditionally described by including a measurement of parallel offset between the shafts. However, the angularity at flex-planes instead of parallel and angular offset of the shafts to define alignment quality is a fundamental point in this paper.

Rigid foundation for induced draft fan. Spring isolated inertia block with motor and pump. How to download shaft alignment handbook files to my device? Click download file button or Copy shaft alignment handbook URL which shown in textarea when you clicked file title, and paste it into your browsers address bar.

In the event of a grounding, for instance, small movements at the shaft bearings can impact bearing loads, leading to premature alignment failure. Shaft alignment handbook pdf. One owner who recognised the importance of monitoring shaft alignment was Stelmar, following the grounding of its aframax tanker Keymar. What is shaft alignment ? This single source reference offers a comprehensive analysis of coupled rotating machinery systems, providing practical guidelines for solving complex alignment tasks fast and accurately.

There are literally countless different indicator setups and shaft alignment methods that utilize this principle, primarily based on the issue discussed herein regarding the increased probability of measurement accuracy. Rotating machinery is the heart of many industrial operations, but many engineers and technicians perform shaft alignment by guesswork or with limited knowledge of the tools and methods available to accurately and effectively align their machinery. This four-day Complete Course on shaft alignment is the most comprehensive training available worldwide. It is recommended for anyone who is responsible for installation, maintenance, and managing reliability of rotating machinery.

If the shaft is free, rotate the shaft degrees and take another set of plumb readings. If the dogleg is real, the second set of readings should verify this. The dogleg should simply move from the north-south plot to the east-west plot or vice versa. The purpose of this document is to provide fundamental information and to guide the industry on Balance and vibration technology as applied to impellers used in air moving systems. It includes terminology used and methods of Balancing practiced by the industry.

Improper alignment leads to increase of stresses in the shafts and thus on the equipment, which might result in break down of the machine. IMPORTANT CONSIDERATIONS BEFORE STARTING ALIGNMENT  MAKE SURE THAT RUNOUT AT THE SHAFT AS WELL AS COUPLING IS LESS THAN 0. SEE FIGURE RUNOUT SHOULD NOT EXCEED 0. MM  DECIDE WHICH MACHINE WILL BE KEPT STATIOARY AND WHICH ONE WILL BE MOVED. GENERALLY, FOR A MOTOR PUMP COMBINATION ,.
