一台NHL3307型矿用车装配的康明斯KT(A)1150型柴油机,重负荷运行过程中水散热器口不断有水喷出。检修人员认为是节温器开度不够引发冷却液高温所致。因此拆掉节温器使其只进行大循环,但故障依旧。
A Cummins KT (A) 1150 diesel engine equipped with an NHL3307 mining vehicle continuously spouts water at the water radiator port during heavy-duty operation. Maintenance personnel think that is not enough to open the thermostat caused by high temperature coolant. Therefore remove the thermostat so that it will only cycle, but the fault still.
