Cummins Generator Cooling Water Tank Freezing Resistance Treatment Method

Today, we will briefly introduce the freezing resistance treatment method of Cummins generator cooling water tank.

Fault phenomenon: The cooling water does not circulate and the Cummins generator overheats. Cause Analysis. The freezing resistance of the cooling water tank mostly occurs in the cold winter in the north, mainly due to the following reasons: the Cummins generator runs out of water in winter; the cooling water tank is too fouled and the cooling water circulation is not smooth; the winter is cold, and the Cummins generator is parked outdoors for a long time. Longer, the cooling water freezes.

Approach: When observing the water temperature gauge, its indication exceeds the specified value, and if you touch the water tank with your hand, you still feel the freezing resistance of the water tank; Open the steam valve cover of the water tank, if there is boiling hot air discharged, it means that the cooling water is not circulating, and the water tank has freezing resistance.

The most prone to freezing resistance in the cooling system is the connection between the lower chamber of the water tank and the water pump and the center of the water tank. When freezing resistance occurs, it can be baked with fire; you can also pour hot water at about 80°C into the water tank, and then pour it again after a few minutes, and this fault can be eliminated after a period of time. At this time, attention should be paid to check the cause of freezing resistance to prevent the failure from happening again.

The measures to prevent the freezing resistance of the water tank are: when the Cummins generator is running in winter, the cooling water should be added in time, and it is best to add antifreeze in the cooling water; when the cooling water tank is too fouled, the water tank should be shut down to clean the fouling to ensure cooling. The water circulation is smooth, and the heat dissipation water tank is good for heat dissipation; if the Cummins generator is parked outdoors for a long time in winter, 60~80°C hot water should be poured into the water tank before starting the machine. After the cooling water temperature rises, the Cummins generator warms up behind Can start to run.
