Abstract

The invention provides a water pump assembly used for diesel engines. The water pump assembly used for the diesel engines comprises a belt pulley, a belt pulley hub, a water pump body, a water seal and an impeller which is matched with a volute of the water pump body, wherein the belt pulley hub is arranged in the belt pulley, and is fixedly connected with one end of the water pump body together with the belt pulley; a water pump bearing in the other end of the water pump body is fixedly provided with the water seal; the impeller is fixedly arranged on a shaft between the water pump bearing and the water seal; the other end of the water pump body is sealed by a pump cover. The water pump assembly used for the diesel engines, provided by the invention, is simple, compact and novel in structure, and the size of the water pump assembly is smaller than those of similar water pumps of other types; moreover, the water pump assembly can be conveniently arranged in various compact diesel engines; the water pump assembly is light in weight, small in pressure surge, stable to work, reliable in performance and long in service life.

Description

technical field [0001] The invention relates to a water pump assembly, in particular to a water pump assembly for a diesel engine. Background technique [0002] At present, the water pump assembly used for diesel-powered engines has relatively high technical requirements. For example, it is necessary to achieve a water pump speed of 6680r / min, a flow rate of 95L / min, a head of 12m, and a temperature of 92±2°C under the condition of an engine speed of 700rpm-7200rpm. The transmission ratio is 1:1.67, the maximum power is 0.8KW and so on. Therefore, in the past, there was no independent design by enterprises in China, all of which were imported from abroad and produced domestically. Moreover, these designs are often bulky, and the shape of the impeller causes large liquid flow resistance, and the clearance between the volute and the volute is unreasonable, resulting in unreasonable flow and noise of the pump assembly. stable defects. Contents of the invention [0003] The ...
