Description

Cooling water pump of automobile engine

Technical Field

The invention relates to the technical field of water pumps, in particular to an automobile engine cooling water pump.

Background

The conventional mechanical water pump is mostly adopted in the general engine, namely, the water pump impeller is driven to rotate by the water pump belt pulley to realize the water pumping function of the water pump, the rotating speed of the mechanical water pump can be increased along with the increase of the rotating speed of the engine, so the supply amount of the cooling liquid is also increased along with the increase of the rotating speed of the engine. The maximum water pumping quantity of the mechanical water pump is designed according to the cooling requirement of the full-load working condition of the engine, and the water pumping quantity of the mechanical water pump is larger than the cooling requirement of the engine under the working conditions of cold start, warm-up and small load of the engine, so that the warm-up time of the engine can be prolonged, and adverse effects of insufficient combustion, carbon deposition in combustion, excessive emission and the like in the warm-up process can be caused. The coolant flow required by the engine under different operating conditions is different.

The existing water pump can only meet the better cooling efficiency of the engine under the specific working condition. When the engine works under different loads, the flow of the cooling liquid provided by the water pump is unchanged, so that the phenomenon of overcooling or overheating of the engine can occur in the running process, and the service life of the engine is influenced. Some advanced engines mostly adopt an engine thermal management module to control a cooling system, and the common control mode is to adjust the size of a water outlet of a cooling water pump or adjust the size of the sectional area of a water inlet of cooling water, so that the water volume of the pump is adjusted. The cooling system controlled by the heat management module is often structurally arranged, occupies large complex space and is controlled by a cooling liquid circulation control mechanism in a complex way, so that the number of parts of the engine is greatly increased, the weight of the engine is increased, and the cost is increased. In addition, under the heating working conditions of warming up, cold starting and the like, the heat management module controls zero water supply or a small amount of water supply, but the water pump is still in the state of pumping water to do work, so that the pressure near the water opening of the water pump is increased, cooling liquid bubbles are increased, the serious result is that the leakage of the cooling liquid is increased, and parts in the water pump are damaged by cavitation erosion. And under the heating working conditions of zero water supply or little water supply and the like, the water pump still works under the conventional water pumping quantity, so that the power of the engine is consumed.
