The invention relates to an arranging structure for a cooling water pump, in particular to an arranging structure for a cooling water pump of a single-cylinder water-cooled diesel engine, and belongs to the technical field of cooling water pumps of diesel engines. The arranging structure comprises the cooling water pump, one end of an impeller shaft of the cooling water pump is connected with a water pump connector which is connected with a flywheel through a bolt, one end of a water return pipe is connected on a water return port of the cooling water pump while the other end of the same is connected with a water outlet of a radiator, a cylinder cover and a cylinder jacket are arranged on a diesel engine shell, a water inlet of the radiator is connected with a cylinder cover water outlet on the cylinder cover through a second water incoming pipe, a water jacket is arranged in each of the cylinder cover and the cylinder jacket, the water jacket of the cylinder cover is connected with that of the cylinder jacket through a water supply pipe, the water jacket of the cylinder jacket is connected with one end of a first water incoming pipe, and the other end of the first water incoming pipe is connected with a water outlet of the cooling water pump. The arranging structure is reasonable in design, convenient to mount and high in transmission efficiency, and difficulty in arranging of the whole engine is lowered.
Description
technical field [0001] The invention relates to an arrangement structure of cooling water pumps, in particular to an arrangement structure of cooling water pumps for single-cylinder water-cooled diesel engines, and belongs to the technical field of cooling water pumps for diesel engines. Background technique [0002] At present, the water pump in the domestic single-cylinder diesel engine cooling system is generally arranged on the gear chamber cover of the diesel engine, and the gear transmission is adopted. Since the gear chamber cover also arranges the crankshaft, camshaft, balance shaft, oil pump, governor, etc. Components are generally difficult to arrange due to the structural space constraints of the diesel engine. In recent years, the overall structure of the diesel engine is becoming more and more compact and lightweight. The space for diesel engine layout will be further reduced, and the layout of diesel engine accessories will become more difficult. There are als...
