Five major factors causing non-circulating coolant in Cummins generator sets

Cummins generator setIt is a Haixing unit. During the process of contacting customers, the staff actively solved various questions for everyone. Among them, there were many inquiries about the non-circulating coolant problem of the unit. Here, Haixing will briefly explain to you the problems caused by the coolant. Five major reasons for non-circulation.

Non-circulating coolant can be caused by:

(1) The radiator fins of Cummins generator set are blocked or damaged. The cooling fan does not work or the radiator is clogged, the coolant temperature does not drop, and the water tank is rusted and damaged, causing leakage and poor blood circulation.

(2) The thermostat of the Cummins generator set is faulty. The engine combustion chamber is equipped with a thermostat for the purpose of controlling the engine combustion chamber. If the thermostat is open at the specified temperature (82 degrees), it will help small circulation. If there is no thermostat, the coolant cannot maintain the circulation temperature. This may cause a low temperature alarm.

(3) If there is mixed gas, the pipeline of the Cummins generator cooling system will be blocked, and damage to the suction expansion tank valve and discharge valve will affect the direct pressure of the cycle. Then always check if the pressure value meets the regulations, the suction pressure is 10kpa , exhaust pressure is 40kpa, in addition to the work of the exhaust pipe, it is also an important factor to judge blood circulation.

(4) The coolant level is low or does not comply with the Cummins generator set. Low liquid level can be a direct result of increasing the cooling water temperature. This will cause non-circulation of the coolant. The coolant of the component is 50% antifreeze + 50% demineralized water DCA4. If it is not specified, the pipe will be blocked and The inner wall of the inner pipe will rust, so the coolant cannot circulate properly.

(5) Water pump Cummins generator set failure. Check whether the water pump is working well, the water pump will not work properly if the drive gear pump is worn. Must be replaced with new ones for normal circulation.

Through the five aspects introduced above, you can also briefly understand the causes of coolant failures in Cummins generator sets. On the one hand, you need to pay attention to the quality when purchasing coolant, and on the other hand, you must strictly abide by the operating instructions to ensure the quality of the unit. normal operation.
