Precautions for correct water discharge of geneset
Precautions for proper drainage
1.The radiator cover should be opened when discharging water. If not opened,though part of the cooling water can flow out,as the amount of water in the radiator decreases, a certain degree of vacuum will be generated due to the closed radiator.And then will slow down or stop the water flow. It will frozee the spare parts due to the water discharging in winter.
2.It is not advisable to drain the water immediately at high temperature. Before the engine is turned off, if the engine temperature is high, do not stop and drain the water immediately. The load should be removed first and let it run at idle speed.When the water temperature drops to 40-50℃,then drain the water.By following the above instruction, it is able to prevent the temperature of the outer surface of the cylinder block, cylinder head, and water jacket in contact with water from suddenly dropping due to the sudden release of water and shrinking sharply. But the temperature inside the cylinder is still very high, and the shrinkage is small, Cylinder block and cylinder head are prone to cracks due to excessive temperature difference between inside and outside
3.The engine should be idling after the water is discharged in the cold winter. In the cold winter, the engine should be started and idling for a few minutes after the cooling water in the engine is discharged. The water pump and other parts may retain some water after the water is discharged.After restarting,the remaining heat can dry the residual water in the water pump, which can ensure that there is no water in the engine, and prevent the water pump from freezing and tearing the water seal and causing water leakage.
