Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0024] Such as figure 1 As shown, an engine cooling system includes a cooling water circulation pipe, a temperature sensor and a water pump arranged on the cooling water circulation pipe. The temperature sensor is used to detect the inlet water temperature of the engine (the inlet water temperature of the engine refers to the temperature when the cooling water enters the water cavity of the engine).

[0025] The water pump includes a water pump housing 1, a drive shaft 11 provided on the water pump housing 1, a shaft sleeve 10 coaxially provided on the drive shaft 11, and a water inlet 13 and a water outlet 3 provided on the water pump housing 1. One end of the shaft sleeve 10 extends into the inner cavity of the water pump housing 1, and the other end is located outside the water pump housing 1. The shaft sleeve 10 is rotatably arranged on the water...

Abstract

The invention discloses an engine cooling system and aims at providing an engine cooling system capable of meeting the cooling water amount needed for high-speed and high-load running of an engine and also capable of effectively shortening the engine heating time in the cold start process of the engine. The engine cooling system comprises a cooling water circulation pipeline and a water pump arranged on the cooling water circulation pipeline. The water pump comprises a water pump shell, a drive shaft arranged on the water pump shell, and a shaft sleeve coaxially arranged on the drive shaft. One end of the shaft sleeve extends into an inner cavity of the water pump shell, and the other end of the shaft sleeve is located outside the water pump shell. The shaft sleeve is rotationally arranged on the water pump shell, and the shaft sleeve and the drive shaft can relatively rotate. The drive shaft is provided with a first impeller, and the first impeller is located in the inner cavity of the water pump shell. The shaft sleeve is provided with a second impeller, and the second impeller is located in the inner cavity of the water pump shell. The drive shaft is provided with a drive belt wheel, and the drive belt wheel is located outside the water pump shell.

Description

Technical field [0001] The invention relates to the field of engine cooling systems, in particular to a water cooling system engine cooling system. Background technique [0002] When the engine is working, the gas temperature in the cylinder can be as high as 1727-2527 degrees Celsius. If it is not cooled in time, the temperature of engine parts will be too high, especially the parts directly in contact with high-temperature gas, which will affect the normal fit clearance due to thermal expansion. As a result, moving parts are blocked or even stuck; in addition, high temperature will also cause the mechanical strength of engine parts to decrease, and the lubricating oil will lose its function. Therefore, the setting of the engine cooling system has a vital influence on the performance and safe use of the engine. [0003] The water-cooled engine cooling system is a commonly used engine cooling system. The cooling medium of the water-cooled engine cooling system is cooling water (co...
