Currently the industrial enterprises pay more and more attention to the increase of the reliability
of equipment under operation and reduction of operating costs for maintenance. As is known in order
to identify and to predict technical conditions of the pumps, compressors and other centrifugal equipment,
the most informative is periodical monitoring of the vibro-acoustic conditions of the machineries and
subassemblies.
NIPIgaspererabotka renders services for taking measurements, investigation of the causes of high vibration level,
development and implementation of measures intended for vibration reduction to the allowable levels for the particular
pumping-compressor sets, ventilation units of different design, electrical motors, piping, process equipment, etc.
In the result of vibration examination the following can be detected:
- defects of installation of foundation frames for machinery sets on the foundations;
- quality of abutment of machinery supporting surfaces in the set to subframes;
- deformation of the bearing surfaces of the machineries and subframes;
- loosening of the fixation of machinery to subframes and frames to foundations;
- rotors imbalance;
- axis misalignment of rotors shafts in the set;
- bend and shaft beat;
- hit of rotor elements against starter;
- defects of sliding bearings and antifriction bearings;
- failures of bearing lubrication system;
- defects of gear drives;
- defects of impeller blades;
- causes of vibration of piping systems and equipment;
- disturbances of uniform flowing, etc.
Based on the wide experience in the performance of the above mentioned activities at gas processing and
oil-refining industries our staff develops and implements in the industry the expert systems for diagnosing
and technologic forecasting of centrifugal machinery technical conditions, provides detection of defects in the
assemblies and machineries at the stage of their origination, monitoring the dynamics of defects developing,
in due time to determine the necessity and intervals of repairs depending on the actual equipment conditions.
In the examination and diagnosing of equipment vibration we use vibration meteringf and vibration analyzing instruments by
Diamekh and ViKont (Moscow), Shenk (Germany) and Brulle&Kier (Sweden).
Rendering of engineering services regarding vibration adjustment of equipment:
- elaboration of proposals and recommendations for client on the subject of elimination of the equipment condition defects, detected in the process of vibration examination;
- machine rotor balancing in proper bearings;
-elimination of shaft axis misalignment;
- elaboration of methods for vibration diagnostics of the equipment in operation;
- personnel training in bases of equipment vibration diagnostics;
- rendering of different technical assistance to maintenance and operating personnel
Work execution in equipment vibration adjustment together with engineering and maintenance personnel
of enterprises allows speeding up considerably a process of introduction of enterprises being developed and
their technical-and-economic efficiency.
In close cooperation with you, we will help you in the shortest possible time to make certain of the necessity
to master vibration methods of the equipment diagnostics with further switch to its condition-monitored maintenance.
