Vibration diagnostics
"...During field application of the system software, it proved itself as a reliable system with authentic results of diagnosed states of rotor equipment. Now over 100 units of principal and auxiliary rotating equipment: turbogenerators, pumps and compressors, fans, smoke exhausters, etc.- are serviced with help of "DIAES" system.
"DIAES" allows to reveal more than 30 types of mechanical and electrical failures: imbalance and misalignment of shafts, defects of rolling bearings, sliding bearings, driving wheels, basements, etc..."
"...Detection of defects at early stage of their development allows to execute timely stops and repair of machines according to indications of the program, to refuse repair of serviceable equipment. This makes it possible to reduce maintenance costs and, in turn, to pays back costs on the "DIAES" program acquisition in a short term."

"... The DIAES system proved itself as a reliable and simple at operation instrument. It can be recommended for application at enterprises of chemical industry for determination of schedule and volume of repair works, prevention of emergencies and further transition to repairs based on real state of equipment."
"...On the basis of more than two years operating experience it is possible to draw a conclusion that the system provides sufficiently valid (about 90%) results of diagnostics and can be recommended for implementation in chemical industry for prevention of emergencies and estimation of schedule and volume of repair works."

"...During the exploitation the DIAES system proved its high efficiency as an instrument for early fault detection and prevention of excessive spending on repairs. This generally affects increased reliability of equipment and prevents downtimes. The program allows to add unlimited number of new machines, to customize diagnosed parameters, to add new defects basing on practical experience."

"... Since July, 1998 the diagnostics system for rotating equipment, developed by ZAO "PromServis", was put into operation at JSC "OEMK". The assessment of economic efficiency of the System operability is based on the example of equipment in metallization department: gear units and compressors of technological and cooling gases. The economic effect of Diagnostic Systems implementation in 1999 amounted to 20 336.8 US Dollars."
"... All jobs were executed by specialists of ZAO "PromServis" within schedule fixed in the contract, and in correspondence with requirements of Rostechnadzor standards, including norms and rules for objects using nuclear power. We have no reprimands to quality of the performed jobs. ZAO "PromServis" is considered as reliable and perspective partner for long-term cooperation."

"...Portable expert diagnostic system "DIAES" allows to detect main mechanical failures in a standalone mode: imbalances and misalignment of shafts, defects of rolling and sliding bearings, defects of blades in rotor wheels, defects of basements, etc. Application of the system enabled timely identification of progressing damage of bearing in a support No. 3 of the pump No. 200D90, working in continuous production mode. Execution of regular inspections allowed to control development of this defect, to last out operation time till planned stop and carry out scheduled repair. After start of operation defects were not found."
"... During operation, at execution of scheduled repairs the system "DIAES" proved its high performance as an instrument for early fault detection and prevention of excessive repair costs that in general leads to improved reliability of equipment and avoidance of downtimes."
"...The system identifies the following failures with high level of reliability: defects of rolling bearings and sleeve bearings, shafts imbalance, defects of basements, lack of basements setup stiffness, etc. as well as defects of electromagnetic system of electric motors."

"...ZAO "PromServis" executed the following works for the Balakovo NPP: "Postreactor researches of fuel assembly in the unit 1 No. 390900407". Within this operation specialists also summarized data concerning construction features, history and parameters of maintenance of fuel assembly-2 No. 390900407 and other not hermetic fuel assemblies. The work was completed at a stated time and with appropriate quality."
"...The Laboratory of Technical Diagnostics (LTD) of KNPP carried out verification of diagnostic system "DIAES" since May to November, 2002 on the equipment of turbine shop, reactor shop, ventilation and air conditioning shop. In the process of diagnostics different types of defects were detected by means of "DIAES" system and eliminated."
"...In 2009 the Board of management of JSC "SIBUR Holding" adopted a decision to state "The Program of implementation of advanced methods of fixed assets maintenance at JSC "SIBUR Holding" enterprises. Within this Program the following measures were taken at our enterprise with the help of ZAO "PromServis" specialists:
- Implemented portable instruments and systems of vibration control and diagnostics "VIES" and "DIAES";
- organized training and certification of personnel engaged in equipment maintenance and diagnostics;
- determined the list of the most critical equipment; developed and implemented the Company Standard "Organization and execution of works on vibration control, diagnostics and monitoring of dynamic equipment at JSC "Tomskneftekhim";
- special file share on the enterprise server is dedicated to store data bases, results of diagnostics, reports, etc."

PJSC “Nizhnekamskneftekhim” cooperates with ZAO “Promservis” for more than 15 years. During this time, Your Company regularly helped us to evaluate technical state of compressor equipment in very difficult situations. Your personnel proved themselves to be highly qualified and responsible specialists, their opinion should be relied on in making the most difficult decisions.
Basing on vibration analysis, specialists of “Nizhnekamskneftekhim” and “Promservis” set up recommendations for control of equipment technical state, thereby service life of units E-501 and E-601 in the workshop No. 2106 of Ethylene plant was extended by 8640 hours. This helped to reduce maintenance and repair costs significantly.
With help of ZAO “Promservis” we managed to solve long-standing problem with the pump unit P-1005A in the workshop No.5804: resonant in support system was revealed that used to cause permanent hardware breakdowns. After tightening of the supporting structure with additional stiffeners the unit returned to normal condition. It is only one of examples of successful problem handling.
Our cooperation in the field of diagnostics and condition monitoring of compressor equipment allows to:
- Reduce risk of production lines’ emergency stop and, consequently, reduce risk of financial losses caused with underproduction;
- Timely start repair works and maintain the best condition of machines;
- Carry out repair works basing on analysis of objective vibration data that indicate actual technical state of equipment.
We hope for further cooperation with ZAO “Promservis”.

Comment regarding diagnostic system for rotating equipment in the hire-and-repair shop for power-generating equipment.
The Sutorminsk drilling department bought from ZAO “Promservis” the diagnostic system with PR200A device in June, 2000. Specialists of “Promservis” provided training for personnel and adjustment of the system.
Today the system is applied for examination of technical state of motors: asynchronous slip-ring induction motor AKB 13-62-8UHL2 (560 kW), synchronous brushless motors SMBO 15-49-8U2 (630 kW), SDBM 99-49-8U2 (710 kW), SDBM 99-46-8U2 (630 kW), SDBM 99-46-8U2 (500 kW) that come for repair.
We execute inspections both before repair (for optimization of labor costs and spare parts), and after it (for output control).
In the first quarter of 2001the System helped to detect production defect in a batch of new electric motors delivered from manufacturer. In three of five arrived motors AKB13-62-8UHL2 the following defects were found: shaft bending, crack of inner race in front bearing and severe wear of outer and inner race in back bearing. After dismantling in the presence of manufacturer’s representative all defects were confirmed.
During the operation and execution of scheduled repair works the System proved its outstanding efficiency as means of early detection of defects and prevention of excessive repair costs. Consequently it allows to increase reliability of equipment and to exclude downtimes.
