Abstract
The object of the study of this article is hydrodynamic processes in the high-pressure fuel system of the ship's medium-speed diesel engine in variable conditions. The aim of the study is to create a method of dynamic motorless testing of medium-speed diesel engine fuel equipment with a variable position of high-pressure fuel pump rail under corresponding modes of load characteristics. The article discusses the results of an experimental study of high-pressure fuel equipment of a medium-speed engine when repositioning the high-pressure fuel pump rail in the corresponding modes of load characteristic and studies the processes of fuel injection in variable and partial modes at the department of ship power plants. The National University “Odessa Maritime Academy” has developed a dynamic test method, created a hardware-software complex for the purpose of controlling fuel equipment operation modes and keeping of fuel supply processes records. Also, an electromechanical module has been created as an actuator for a package of control of load characteristic modes. The basic equipment was the motorless stand equipped with a fuel injection system for a ship’s medium-speed diesel engine ChN25/34. The cam shaft driving gear of the stand is carried out by a direct current motor with an infinitely adjestable speed.
The parameters of the fuel equipment obtained while conducting experimental study, allow to obtain the load characteristics quickly at stepwise movement of high-pressure fuel pump rail, while at the same time ensuring the study of transients in the specified range of the rail movement. The technique of dynamic motorless tests provides a given set of parameters when working with various characteristics. The most relevant among them are modern standards of environmental friendliness and efficiency. Designed and implemented software and hardware that performs the functions of managing test modes, recording, data processing and registration of experimental results. An electromechanical complex with computer program control for setting test modes was implemented. The test complex has been adjusted and refined and has been used in the current research work of the Department of Ship Power Plants.
Keywords: experimental research, method of motorless testing, dynamic motorless testing, transient processes, stepwise movement, rail of high pressure fuel pump, software and hardware.
