Do not add ordinary tap water or deep well water to the water tank of the Cummins generator set, because the mineral content in these waters is relatively high, and it is more likely to produce scale once a long time, which can easily lead to clogging of the water tank. And the water tank of the Cummins generator set sometimes has an abnormal situation where the water temperature is low and the water tank “turns over”, so how to solve it?
“Turn the water” is not affected by the temperature of the engine. Even if the water temperature is not high, the coolant in the expansion tank or the radiator will violently toss and the water vapor will overflow. With the increase of engine speed, the phenomenon of “turning the water” intensifies, while “opening the pot” does not exist.
The “turn over” is accompanied by a substantial reduction in coolant. When the “water overturning” is serious, water enters the cylinder, causing the exhaust pipe to emit white smoke. What’s more, there is too much water in the cylinder to start after parking.
There are blisters, corrosion holes, etc. in the exhaust chamber of the air compressor cylinder head and the water jacket, which will also cause the compressed gas to enter the water jacket and cause “turning water”. When “overturning water” occurs, first check whether there is air leakage or water leakage in the cylinder head of the air compressor.
If there is no fault in the air compressor, the oil-cutting method can be used to judge whether the cylinder head gasket is damaged. When performing this inspection, the water tank cover of the Cummins generator set should be opened to observe. When the broken oil cylinder does not work, the water turning of the water tank will stop, and the white smoke from the exhaust pipe will also improve, indicating that the cylinder head gasket of the cylinder is damaged and should be repaired in time. , replace the cylinder head gasket. If there is no damage and no signs of air leakage when inspecting the cylinder head gasket, you can look for blisters and pitting holes, and repair them if any.
