Equipment problems that are not detected in a timely manner contribute to the appearance and accelerated development of defects. This leads to sudden breakdowns, large losses of time, and often disasters. A correct and timely response to a problem significantly increases the reliability and safety of equipment, thereby reducing risks and capital investments in the business.

Prescriptive Maintenance (RxM) is a concept that allows you to effectively manage production equipment by issuing prescriptions for their operation and maintenance.

RxM will allow you to get away from unscheduled repairs of suddenly failed equipment and increase overhaul intervals. Also in the past will remain emergency situations and disasters associated with unacceptable wear and tear of equipment.

Modern operations and maintenance management systems are based on either simple metrics monitoring (CBM) or expert-based predictive (PdM) and prescriptive (RxM) maintenance technologies.

"i-analytics" is a Prescriptive Maintenance (RxM) application for industrial equipment. "i-analytics" is based on the continuous analysis of the technical condition of the equipment by combining signals and telemetry data constantly coming from the equipment. The use of "i-analytics" significantly optimizes many business processes of both large and small enterprises.

early-stage detection of equipment internal parts detects followed by maintenance recommendations for each structural element

"i-analytics" provides customers with comprehensive information about the technical condition of their equipment and instructions for its operation and maintenance. It is available in the user's personal account from any device connected to the Internet.

The best results are achieved by integrating "i-analytics" with production asset management systems (CMMS, MES, ERP). The most efficient way to achieve this integration is through global platforms for the Industrial Internet of Things (IIoT) and Industry 4.0. The main goal of "i-analytics" is to become the core application of RxM.

"i-analytics" works as a cloud service using its own basic functions, wavelet analysis and other digital signal processing (DSP) algorithms, machine learning based on neural networks (Machine Learning, ML) and fuzzy logic algorithms (Fuzzy Logic). It is in these areas that the core competencies of our team of scientists, engineers and experts are concentrated.

"i-analytics" has been tested on engines, rolling mills, compressors, wind turbines and other plant equipment.

Key benefits of "i-analytics":

diagnostics and equipment maintenance management are fully automatic. All algorithms operate in the "cloud" and do not require the participation of human experts;

the application operates with the current state of the equipment, its modes and technological risks at the level of specific parts (wear of the outer ring of a bearing or gear, shaft breakage, shells on rolling elements, etc.);

the application is easily scalable;

work with almost any rotary and piston equipment without the need for a long preliminary “training” of models;

work with a wide range of industrial sensors and other sources of telemetry data;

the possibility of effective integration with automated asset management systems.

fast project implementation and perfect scalability


Equipment

Problem

Maintenance Prescriptions

Rolling bearings of rotating shafts

Defects of bearing and its lubrication (wear, grooves, cracks; grease contamination)

Check the radial clearance in the bearing, the installation dimensions in the housing

Check and eliminate defects along the shaft line (shaft run-out, shafts misalignment, etc.)

Check the integrity of the seals; replace grease

Replace damaged bearing

Non-uniform radial tension

Check the shaft and the bearing for compliance with tolerances of seating surface

Adjust the bearing installation

Asynchronous electric motor / generator

Rotor imbalance

Check for deviation of dimensions from nominal, for cracks, tripping, insertion or sticking of impurity material, rust, etc.

Rebalance the rotor

Defects of fastening of the stator or whole machine to the base, or base to the understructure

Check fastener points

Replace fasteners, repair stator housing parts; check / replace vibration absorbers; replace / reinforce anchor bolts / base (understructure)

Rotating shafts

Misalignment of shafts

Check the coupling elements

Adjust the shaft installation

Gearing

Wear of teeth

Check and monitor the gear teeth, check the tooth contact patch

Replace the bearings if there is no defect in the gear

Centrifugal pump

Imbalance of impeller (displacement of the center of mass of the rotor, incl. hydrodynamic)

Check the impeller for damage of the surfaces of the working and guide vanes, chips, etc.

Replace a damaged wheel

Belting

Defects of pulley (gearwheel) (wear of pulley grooves / gearwheel teeth)

Replace the pulley (gearwheel) with wear of grooves (teeth) and other mechanical defects.
