FUEL INJECTION VALVE TEST APPARATUS FOR SHIP DIESEL ENGINES, EQUIPPED WITH A HYDRAULIC PUMP OPERATED BY AN ELECTRIC MOTOR

摘要

PURPOSE: A fuel injection valve test apparatus for ship diesel engines is equipped with a hydraulic pump operated by an electric motor in order to facilitate pressure control, which has a small number of parts with a simple structure.;CONSTITUTION: A fuel injection valve test apparatus includes the separate pressure control valve (7). Both of the oil draw-in pipe (18) and the draw-out pipe (19) of said pressure adjustment valve are connected to the oil tank (1). The draw-in pipe between the hydraulic pump (4) and the fuel injection valve (12) is interconnected with the oil draw-in pipe of said pressure control valve. Oil from the hydraulic pump flows into the fuel injection valve only after a pressure is raised to the set pressure in the pressure control valve. Said hydraulic pump is connected with one side of the electric motor (3).;COPYRIGHT KIPO 2013
