主机安装注意事项(国外英文资料) The first chapter of ship engine installation Learning objectives The goal of knowledge 1. master host installation work; The contents and methods of learning base for 2; 3. learning methods host hoisting; 4. master host location: according to the shafting flange positioning; according to the theory of midline positioning system; Methods 5. soil fixed machine learning; 6. to master a large low speed diesel engine installation method. The ability to target 1, prepare; 2, the host can hoist; 3. positioning machine; 4. fixed host; 5. parts can be assembled and the disintegration of large low speed diesel engine, crankshaft, main bearing and frame, frame, cylinder, live Plug device and cylinder head. The first section outlines The host is the core of the ship power system, its installation quality will directly affect the normal operation and the navigation performance of marine power plant. The host of the main types of diesel engine, steam turbine and gas turbine, different types of hosts, with structure characteristics and work in different ways, the installation should be according to different models and the corresponding technique in ship. The diesel engine is one of the most widely used host, this chapter mainly discusses the installation process of the diesel engine. The power of the host machine is transferred to the propeller through shaft, and the shaft is connected to the host, the host, shaft and propeller to form an organic whole, so the host installation should be considered together with the installation of the shafting. Shipbuilding, installation sequence and host shafting there has three kinds: the first to host the first shaft safety; then the host security shafting of main engine and shafting system installed at the same time. The first shaft installed in the ship, ship launching, and then to install the mainframe as a reference shaft, this is a kind of installation process has been used. Because of the rotation center of the output
