Automatic cleaned drain piping system on crosshead type two-stroke engines. The invention is having a slow rotating centreless flexible spiral auger fixed mounted in the piping system. The purpose of the invention is to constant avoiding build-up of deposit inside the drain pipes during normal operation. My invention will prevent partly or full blockage of the drain piping. The invention will help to trouble free, reliable and safe continued operation of two-stroke crosshead type engines. The invention will give dramatic savings in man-hours, cleaning chemicals and materials used during manual pipe cleaning. The invention is suitable for mounting during construction of new engines as well as for retrofit. The purpose of the very slow rotating auger is solely to keep heavy, solid and slow flowing particles moving along with the freely flowing oil, thus avoiding deposit building up inside the pipe. The slow rotation speed of the auger inside the pipe creates a scraping action on the lower part of the pipe inner wall, thereby keeping heavy, solid and slow flowing particles in motion.
An automatic cleaning system with rotating flexible centreless spiral auger fixed mounted in piping system draining from piston rod stuffing boxes of an engine, drain piping draining from scavenge air space and piston underside space of the engine, drain piping draining from scavenge air receiver of the engine, wherein a centreless flexible spiral auger fixed mounted in the piping system, where the main transport trough the piping is the free flow of liquid which flows in the hollow part of the centreless flexible auger and in the space between the auger and the inner diameter of the pipe.
