The Problem of Non-Circulation of Coolant in Cummins Diesel Generator Set

In the process of using Cummins diesel generator sets, a common problem is that the coolant in Cummins diesel generator sets does not circulate, which causes the diesel generator sets to fail to operate normally and to work The reduction in efficiency causes the cooling fluid of Cummins generator set to not circulate mainly due to the following points: Cummins diesel generator set water pump failure, check whether the water pump is working well, if it is found that the water pump drive gear shaft is worn out, the water pump has not been able to function. To function, it needs to be replaced before the cycle can be normal.

If the coolant level of the Cummins diesel generator set is too low or does not meet the requirements, it can directly cause the temperature of the coolant to rise and the coolant will not circulate. The coolant is 50% antifreeze + 50% softened water + DCA4 according to the regulations. , Failure to comply with the regulations will cause blockage of the pipeline and rust on the pipe wall, making the coolant unable to circulate normally. When the thermostat of Cummins diesel generator set fails, a thermostat is installed in the combustion chamber of the engine to control the temperature of the combustion chamber of the engine. The thermostat must be opened at the specified temperature to facilitate small circulation. If there is no thermostat, the coolant If the circulating temperature cannot be maintained, a low temperature alarm may be generated.

Air is mixed in the cooling system of the Cummins diesel generator set, which causes the pipeline to be blocked. The damage of the suction valve and exhaust valve on the expansion tank also directly affects the circulation. At this time, you should always check whether their pressure values meet the regulations. The suction pressure is 10kpa, the exhaust pressure is 40kpa, in addition to the second, whether the exhaust pipe is unblocked is also an important reason that affects the circulation. When the radiator radiator of Cummins diesel generator set is blocked or damaged, the cooling fan does not work or the radiator is blocked, the temperature of the coolant cannot be lowered, the radiator is rusted, causing liquid leakage and poor circulation. Knowing the cause of the failure can easily solve these problems, so that the Cummins diesel generator set can work normally.
