Centering geometrical axes of pumps, compressors, gearboxes, fans. — Санкт-Петербург

Centering is ensuring the alignment of the geometric axes of rotation of the mechanisms, i. e. their centers of rotation must be in line. Since it is impossible to ensure perfect alignment, equipment manufacturers indicate tolerances and alignment methods in the installation (operating) instructions or suggest using recommended tolerances from leading manufacturers of alignment equipment, such as BALTECH or Fixturlaser. Recommend tolerances for angular misalignment and parallel displacement depending on the rotational speed. Alignment is necessary to extend the service life of bearings, seals, couplings, reduce power consumption and reduce vibration in the low-frequency region of the spectrum (physically the greatest energy of destruction).
If you do not take into account the methods of centering "with the help of a stick and rope, " then in modern industry mechanical (electromechanical) and laser devices and sets of devices for centering are used. In the technical servicedepartment of the BALTECH company for centering, they mainly use the laser centering system Quantum - LM and Fixturlaser Xa. Alignment with this tool provides the necessary accuracy, automatically creates a alignment protocol, and the presence of application programs ensures ease and speed of work.
As in life, so in technology nothing is perfect. The use of laser devices for centering has a number of limitations associated with a design feature — they do not work at a negative temperature for a long time. With proper organization of the outage, if the equipment is “standing on the street”, all maintenance work must be carried out in the warm season, and emergency centering can take no more than an hour (according to the experience of specialists of thetechnical services department of the company BALTECH ) and the device does not have time to "freeze". As one of the options, the installation over the unit of a temporary heated "dome" (tents) or the use of mechanical (electromechanical) systems for centering the "Kvant" series, adapted to work at negative temperatures. Alignment of geometric axes of pumps, compressors, gearboxes, fans.
