Cummins diesel generators generate heat when they run,
leading to an increase in body temperature.
When the body temperature rises to a certain extent,
it will affect the efficiency of Cummins generator.
Therefore, measures are taken to keep the engine and AC Cummins generator at a low temperature.
The cooling system includes a radiator, axial fan and thermostat. Ac Cummins generator with individual fan cooling.
What is the composition and function of Cummins generator cooling system
Radiator: Various dirt on the radiator chip will greatly reduce the cooling performance of the radiator, so it is necessary to clean the radiator frequently in a dusty environment.
Coolant: Engine coolant has three functions: to provide sufficient force transfer; Prevent corrosion of all metal materials in the cooling system; Provide adequate frost protection.
Select qualified brands of coolant to ensure the normal use of the engine. The coolant should be mixed with water, antifreeze or water and antirust liquid, where the PH value of water should be 6 to 8.
The coolant should be contained in the freezing area 40* ~ 60* It is recommended that the user use antifreeze 50* Cummins generator antifreeze and 50* pure water mixture should be prepared separately in an independent container, mixed evenly and added to the tank, and the antifreeze capacity can reach about -30 ℃. (See antifreeze user instructions for details).
Antirust fluid can be used in areas where there is no risk of freezing, rather than antifreeze. The mixing ratio of anti-rust liquid and pure water is 1:30, which can achieve better anti-rust cooling performance without reducing the Cummins generator. After the Cummins generator is filled with anti-rust liquid, it should be used to run to the heat engine state to obtain anti-corrosion protection.
Do not mix different types of antifreeze with additives such as rust prevention, as it will produce a large amount of foam and reduce its cooling performance.
Add coolant: Coolant can be added after the Cummins generator is shut down and completely cooled. The Cummins generator should not be started until the system is ventilated and coolant filled.When injecting coolant, the liquid level should reach 5 cm below the welded surface of the injection port (or the coolant level indication scale). After the coolant is filled, the Cummins generator should be started and preheated to check the coolant surface and determine whether the coolant needs to be replenished.
The coolant of the same specifications as the original cooling system should be the coolant. Before adding coolant to the cooling system, ensure that the drain cap is closed and the drain plug is located in the correct position.Add coolant slowly and evenly to avoid bubble faulting in the system. The air of the cooling system is discharged through the filling port or exhaust valve. If the cooling system is connected to the heater, the control valve of the heater is opened to maintain ventilation in the unit.The Cummins generator part is equipped with a coolant filter, and the filter valve is opened before being officially put into use.
