Optical assembly for laser alignment of shafts

Abstract

The article presents a new method of increasing laser radiation power of the receiving device while performing align- ment for reducing excessive pump vibration. The optical arrangement and device design are presented. The possibility of application of glass system with definite refraction index of laser beam system sweeping in a line direction is theoretically justified. The paper presents that the beam sweeping in immediate proximity to a receiving device allows to increase the "beam force/disturbance force ratio" without increasing the laser power. The results of the experimental comparative testing are described. The experiment was conducted in plant conditions of Formation Pressure Maintenance Depart- ment OGPD Tuimazaneft, group modular pumping station BKNS-20C using CNS 63-1400 (sectional centrifugal pump) in cooperation with specialists of Oktyabrsky URONO LLC "OZNA".
