The cylinder block design of Cummins diesel generator set is durable, low vibration and low noise; In-line six-cylinder four-stroke, smooth operation, high efficiency; Replace wet cylinder liner, long life, easy maintenance; Two cylinders one cover, each cylinder 4 valves, sufficient intake, forced water cooling, small heat radiation, excellent performance.
In the process of using diesel generator set, the problem that often occurs is that the coolant of the generator set is not circulating, which leads to the normal operation of the diesel generator set, making the work efficiency significantly reduced, generator set research center to Cummins generator set as an example for the majority of users to share the reasons for the coolant not circulating and solutions.
The main reasons for the coolant not circulating in Cummins generator set are as follows:
1, Cummins diesel generator pump failure. Check whether the function of the pump is good. If it is found that the wear of the transmission gear shaft of the pump is too limited, it means that the pump has not worked, and it needs to be replaced before the circulation is normal.
2, Cummins diesel generator coolant liquid level is too low or does not meet the regulations. The liquid level is too low, which can directly cause the coolant temperature to rise so that the coolant does not circulate. The coolant is 50% antifreeze +50% softened water +DCA4 according to the regulations. If it does not meet the regulations, it will cause pipeline blockage and rust in the pipe wall, making the coolant unable to circulate normally.
3, Cummins diesel generator set thermostat failure. The engine combustion chamber is equipped with a thermostat, the purpose is to control the engine combustion chamber temperature, the thermostat must be fully opened at the specified temperature to help small circulation, if there is no thermostat, the coolant can not maintain the circulation temperature, may produce a low temperature alarm.
The gear centrifugal pump is used in the engine of Cummins generator set to force water cooling, and the large flow water channel design has good cooling effect and can effectively reduce heat radiation and noise. The unique rotary water filter prevents rust and corrosion, controls acidity and removes impurities.
