Study on the Assembly and Adjustment Technology of the Low-Speed Marine Diesel Engine

Abstract:

This paper takes the high-power low-speed marine diesel engine as an object to carry out a series of technical researches. These technologies include the assembly and the precision adjustment on the components of the piston, the crosshead and the connecting rod, and the assembly and the timing adjustment on the fuel and exhaust system, the assembly and the precision adjustment on the crankshaft and the engine base. The test technology and system of the high-power marine diesel engine are studied. The new method to determine the assembly quality of the piston and crosshead based on the strain measurement for the small end of the connecting rod and the oil film thickness measurement for the crosshead and the supporting plate is proposed. The stress measuring system for the engine body is built. The engine body’s deformation before and after the crankshaft assembly and the bearing block’s deformation during the crankshaft movement are analyzed to evaluate the stress situation of the crankshaft after the installation. Therefore the assembly technology for the low-speed high-power diesel engine is improved to ensure the reliability of the diesel engine work.
