Abstract

The invention provides a water pump assembly for a diesel engine, which includes a pulley, a pulley hub, a water pump body, a water seal and an impeller matching the volute of the water pump body, the pulley The wheel hub is arranged in the pulley, and is fixedly connected to one end of the water pump body together with the pulley, and a water seal is fixed on a water pump bearing in the other end of the water pump body, and the impeller is fixed to the On the shaft between the water pump bearing and the water seal, the other end of the water pump body is covered by a pump cover. The water pump assembly for diesel engines of the present invention has a simple, compact and novel structure, smaller volume than other types of water pumps of the same level, and is convenient to be arranged in various compact and small diesel engines. The water pump assembly has the advantages of light weight, small pressure fluctuation, stable operation, reliable performance and long 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 ...
