Currently, dozens of enterprises use automatic diagnostics and long-term
condition prediction systems based on the DREAM software as the main condition
monitoring tool. The list of the vibration measurement instruments compatible
with the system includes following data collectors: DC-11 (produced by VAST, Inc.
in Russia), 2526 (produced by Bruel & Kjaer CMS in Denmark), PL-36 (produced by
Diagnostic Instruments, Ltd. in Scotland), and some other instruments for
vibration measurements.
In 1999 a number of other instruments compatible with DREAM for Windows software
will be launched. For example, the Canadian company, the DPL Group, starts the
production of a vibration analyzer, the DC-11 data collector, which is perfectly
compatible with the software DREAM for Windows and additionally can be used for
multiplane field balancing applications. In addition, it is planned to send data
via ordinary telephone lines in any point of the world. Also, together with the
company Diagnostic Instruments, Ltd., we plan to finish necessary modifications
to make the DI-1100 data collector work with DREAM for Windows package. And an
even more interesting project to be launched in cooperation with Diagnostic
Instruments is EBA (Expert Bearing Analyzer) produced by Diagnostic Instruments
- a new product incorporating the firmware for rolling element bearing in-field
diagnostics based on DREAM algorithms.
From the suggestion of specialists from different industries, we decided to
organize a club of DREAM users. The members of this club and other interested
persons will be provided with the support in monitoring, diagnostic and
balancing systems based not only on the mentioned hardware and software, but
also on the systems with similar technical capabilities.
The club will be chaired by well known experts of VAST Association, Ph.D.
Natalia A. Barkova and Ph.D. Yury A. Azovtsev.
The questions will be replied to by leading experts in practical diagnostics and
machine balancing and the designers of electronic devices and software. We hope
also to involve in the discussions experts of other companies and users with
good practice of using the monitoring and diagnostic systems with software DREAM.
Besides answering the questions, the club organizers are ready to help in
diagnostics and condition prediction in the rare cases when the work of DREAM in
automatic mode of operation cannot solve a problem. The measurements and data
transfer in these cases will be done via Internet or e-mail.
Naturally, the questions similar in sense will be grouped in certain sections so
that to give as detailed replies to the questions as possible. It is supposed
that the questions and answers will be grouped according to the following
sections:
General aspects of monitoring and diagnostics.
Measurements and analysis of diagnostic signals.
The influence of defects on machine and equipment vibration, the diagnostic
symptoms of defects.
Machine balancing in situ.
The diagnostic and balancing technical means.
The peculiarities of the software "DREAM for Windows".
The attendant problems.
The leaders of the club will be grateful for all the persons
interested in the work of the club for their comments and additions concerning
the replies on the questions of the DREAM users.
Nowadays, the club has already issued the recommendations for monitoring and
diagnostics systems: The Rotating Machines Monitoring and Diagnostics by
Vibration Signal in Russian language. The English version of these
recommendations is under preparation. Moreover, a text book, The Machine and
Equipment Vibroacoustical Diagnostics is in intensive preparation.
It is intended that VAST Association will circulate additional information and
working materials to the DREAM software users, so those who work with this
software are kindly asked to register in the club and receive their
identification number.
After the information about the DREAM for Windows users club organization, a
letter from Dr. Alexej V. Barkov, the President of VAST, Inc., is attached.
You can also use the fax machine: +7 (812) 251 9145
And now we are waiting for your proposals for the club work, questions and
comments and history cases with your work with DREAM for Windows software and
monitoring and diagnostic systems on its basis.
