A Fuel Gas Supply High Pressure Pumping Apparatus of Liquefied Natural Gas with Unify of Maine Power and Auxiliary Power

摘要

The present invention is to simplify the configuration by unifying the operation of the main pumping cylinder and the preliminary pumping cylinder to pressurize and supply LNG fuel to the ME-GI engine, and to prevent the increase in cost and the production period due to production. An LNG fuel engine supply high pressure pumping device for supplying to the engine by pumping and pressurizing LNG fuel, comprising: a main and preliminary pumping cylinder group comprising a plurality of piston-type main and preliminary pumping cylinders, respectively; Main and preliminary drive shafts to which the main and preliminary piston rods of the piston-type main and preliminary pumping cylinders are respectively connected; A clutch gear means connected to the main and preliminary drive shafts to transmit power of the drive source to the main drive shaft or preliminary drive shaft selected from the main drive shaft and the preliminary drive shaft; Provided is a high-pressure pumping device for supplying LNG fueled by a main drive and a preliminary drive, which are configured to include.
