Specialists from SKB-3 (part of the military-industrial holding company "Kingisepp Machine-Building Plant", KMZ) have improved the technology for casting flanges of working cylinder liners for the "Russian Diesel" line of diesel engines. This was reported by the holding's press service.
The liner is a metal cylinder on which a cooling jacket is installed. The flange is used to attach the liner to the engine block.
At SKB-3, the problem of slag inclusions entering the molten metal when casting liner flanges was solved. Specialists developed a stepped slag trap, which cuts off the slag, and clean metal is fed into the mold.
The owner of the technical documentation for the "Russian Diesel" engines (a closed plant in St. Petersburg) is the Ministry of Defense of the Russian Federation. Then it was transferred to KMZ. Now the holding helps the fleet, including repairing engines from this manufacturer.
Earlier, KMZ eliminated defects in the main ship engine "Russian Diesel 70B 18DRPN 23/2x30". It is equipped with remote automated control systems, automatic warning alarms for pressure and temperature circuits of oil, water, and fuel pressure.
