冷却液中混入空气,是造成汽缸套、水泵、水道穴蚀的主要原因。穴蚀严重时,可造成水泵和水散热器性能下降,甚至导致活塞卡滞和柴油机损坏。冷却液中产生空气的原因主要包括以下4点:一是加注冷却液时带入,二是水散热器上水室产生紊流时掺入,三是柴油机汽缸垫密封不严时压入,四是水泵水封密封不严
Coolant mixed with air, is the main cause of cylinder liner, water pump cavitation. Severe pitting can cause the pump and water radiator performance degradation, and even lead to piston stuck and diesel engine damage. The reasons for the air generated in the coolant include the following four points: First, when the cooling fluid into the second, the water radiator on the turbulence generated when mixing water, the third is not tight when the cylinder gasket seal, Fourth, the water pump seal lax
