The invention discloses a cooling system, a control method thereof and engineering machinery. The cooling system comprises a first water tank, a second water tank, a water level monitoring module, a pressure monitoring module, a first switch valve, a second switch valve and a third switch valve. The first switch valve is connected between the first water tank and the second water tank; the height of the first water tank from the horizontal plane is greater than that of the second water tank from the horizontal plane; the water level monitoring module monitors the water level of the second water tank and controls opening and closing of the first switch valve according to the water level of the second water tank; the pressure monitoring module monitors the pressure of the second water tank and controls opening and closing of the second switch valve according to the pressure of the second water tank; the third switch valve is opened when the engineering machinery needs to be cooled, and water in the second water tank is sprayed to the engineering machinery through the third switch valve. According to the technical scheme, by arranging the cooling system, the water level and pressure of the water tank are controlled in a self-adaptive mode, and then continuous and stable spraying cooling of the engineering machinery is achieved.

    本发明公开了一种冷却系统及其控制方法和工程机械。该冷却系统包括第一水箱、第二水箱、水位监测模块、压力监测模块、第一开关阀、第二开关阀和第三开关阀;第一开关阀连接在第一水箱和第二水箱之间;第一水箱的距离水平面的高度大于第二水箱的距离水平面的高度;水位监测模块监测第二水箱的水位,并根据第二水箱的水位控制第一开关阀的开闭;压力监测模块监测第二水箱的压力,并根据第二水箱的压力控制第二开关阀的开闭;第三开关阀在工程机械需要冷却时打开,第二水箱中的水通过第三开关阀向工程机械喷淋。本发明实施例的技术方案,通过设置冷却系统,实现自适应控制水箱的水位和压力,进而实现对工程机械持续稳定地喷淋冷却。
