Description

technical field [0001] The invention relates to a production process of a cooling water pump for a high-speed gear box, belonging to the technical field of auto parts. Background technique [0002] When the internal combustion engine is working, it needs to be cooled to prevent the temperature from rising. Usually, the cooling water pump is used to press the cooling water for water cooling; due to the complex structure of the internal combustion engine, the internal cooling channel is curved and narrow, and the resistance to water flow is large. The size of the flow rate has become the key to the cooling effect of the internal combustion engine. [0003] Most of the existing cooling water pumps for high-speed gearboxes are mechanical water pumps. The operation of the water pump depends on the engine shaft drive. When the engine speed is high, the water pump speed is high and the flow rate is increased. When the engine speed is low, the flow rate is reduced; At this time, th...

Problems solved by technology

[0003] Most of the existing cooling water pumps for high-speed gearboxes are mechanical water pumps. The operation of the water pump depends on the engine shaft drive. When the engine speed is high, the water pump speed is high and the flow rate is increased. When the engine speed is low, the flow rate is reduced; At this time, the engine itself does not need the cooling system to work, but the engine water pump will start to work with the engine running, which will cause longer engine warm-up time, higher engine fuel consumption, poor emissions, etc., and the flow rate of the water pump cannot be adjusted according to the engine cooling system. needs to be adjusted
