Abstract

The invention discloses a water pump. The water pump comprises a pump body and a blade, wherein a part of the blade is arranged in the pump body, the blade is driven to be capable of moving relative to the pump body so as to enable a distance between one end of the blade located outside the pump body and the center of the pump body to be adjustable. By adjusting the distance between the outer end of the blade and the center of the pump body, centrifugal force provided by the water pump is changed, and further flow adjustment is achieved. For example, when the water pump is used for cooling an engine, the length of the blade extending out of the pump body can be adjusted according to the working condition of the engine, accordingly appropriate coolant flows can be obtained, the engine is fully cooled, engine overcooling or overheating phenomenon of the engine is avoided, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to a water pump. Background technique [0002] At present, the water pump used in the engine cooling system is a constant flow water pump. When this type of water pump works at a specific speed, if the flow resistance characteristics of the outer boundary do not change, the flow rate of the water pump remains unchanged. The coolant flow required by the engine under different operating conditions is different. Existing water pumps can only achieve better cooling efficiency for the engine under specific working conditions. When the engine is working under different loads, the coolant flow provided by the water pump is constant, which will cause the engine to be overcooled or overheated during operation, which will affect the service life of the engine. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. [0004] There...
