The result has been achieved; 6 compressors have been working flawlessly for 9 years and undergo scheduled maintenance. <\/p>\n<p><!-- IESCO-MARKER-EXPANDED --><\/p>\n<h2>The challenge<\/h2>\n<p>The braking system of VMK-type trains is pneumatic and runs on compressed air. The original ABK 0.65 compressors had failed, and replacements turned out to be unavailable on our market.<\/p>\n<p>There were two alternatives: wait for delivery on an uncertain timeline, or build a solution locally.<\/p>\n<h2>The solution \u2014 locally built modernisation<\/h2>\n<p>We used the existing housing and fitted a ROTORCOM (Germany) screw block inside it, coupled it to the electric motor and controlled it from a control panel.<\/p>\n<h2>Why a screw block instead of a piston machine<\/h2>\n<p>The original ABK was a piston compressor. Moving to a screw block was not a like-for-like replacement but a qualitative improvement: a screw machine has far fewer moving parts, with no piston rings or valves, and therefore fewer wear components.<\/p>\n<p>The second reason is vibration. A train is a moving, vibrating platform, and a piston machine is itself a source of vibration, while a screw machine runs far more smoothly. The third is duty: a screw block is designed for continuous operation, which is critical for a braking system.<\/p>\n<p>Keeping the existing housing let us mount the unit in the same place on the carriage, on the same brackets, without altering the carriage structure.<\/p>\n<h2>The result \u2014 nine years<\/h2>\n<p><strong>Six compressors have been running without interruption for nine years<\/strong>, with scheduled maintenance.<\/p>\n<h2>A non-standard task<\/h2>\n<p>If replacements for your equipment are no longer available, tell us and we will look at whether a local solution is possible.
