ET 813 Two-Cylinder Steam Engine Show data sheet (pdf file) Print page
Technical Description

  The ET 813 forms a complete steam power plant with the matched steam generator ET 813.01 and the HM 365 Universal Drive and Brake Unit.

  Heat energy is initially converted into mechanical energy and then into electrical energy by the HM 365 operating as a dynamometer. The trainer ET 813 contains a steam engine, a condenser and a condenser tank together with comprehensive instrumentation. The steam engine is an enclosed two-cylinder machine with 180° crank offset. It is of single action with plunger pistons. The condensate tank is designed as a cascaded tank and separates oil from the steam engine. The clean condensate is pumped back to the feed water tank of the steam generator.
  The measured values can be read on digital displays. At the same time, the measured values can also be transmitted directly to a PC via USB. The data acquisition software is included.
