The principle of tractor radiator is mainly through the coolant circulation between the engine and the radiator, absorbing the heat generated by the engine, and the heat is distributed to the air through the radiator, so as to reduce the temperature of the engine.
The cooling system of a tractor usually consists of a water cooling system, which works in a recirculation manner. The coolant is sucked out of the engine, dissipates heat through a radiator, and is then returned to the engine, a process that helps control its temperature and prevent it from overheating. The radiator is designed to effectively reduce the temperature of the air entering the engine cylinder, improve combustion efficiency, and reduce the damage of thermal stress on engine components. It is usually made of aluminum or copper materials, using dense heat sink structure, increase the contact area between air and heat dissipation medium, so as to accelerate the loss of heat. At the same time, with the forced ventilation of the fan, an efficient heat exchange system is formed to ensure that the engine can maintain a stable operating temperature even under continuous high load operation.
In addition, the radiator of the tractor also involves some maintenance and precautions. For example, the driver can check that the thermostat is working properly, as a malfunction of the thermostat may cause poor engine heat loss. At the same time, it is also necessary to pay attention to whether the radiator is blocked by dust, dirt, etc., because this will affect the heat dissipation effect. Keeping the radiator clean and in good condition is essential to ensure proper operation of the tractor.
Cleaning method of tractor radiator mainly includes the following steps:
Check before cleaning :
Check the tightness of the cooling system and use a pressure tester to check for leaks.
Check the working status of the pump, if there is wear or abnormal should be replaced in time.
Simple cleaning :
When the engine works for a certain number of hours or when the season changes, release the old cooling water, add new cooling water and cleaning agent, preheat the engine and put out the water, repeat this process until the discharged water becomes clean.
Wash thoroughly :
If the radiator has poor performance or excessive scale, it needs to be cleaned thoroughly with a special radiator cleaner. It includes taking out the thermostat, adding the mixture of cleaning agent and coolant, starting the engine to the normal temperature and maintaining idle operation for a certain period of time, then releasing the cleaning liquid and flushing the cooling system channel with clean water until the discharged water becomes clean.
Precautions :
When cleaning the cooling system, do not open the radiator cover directly if the engine is still hot, in case steam or hot water is ejected and burns are caused. You must wait for the engine to cool before turning it on carefully.
Coolant and its additives contain toxic substances, so attention should be paid to avoid direct contact and keep them in a safe place when using.
Through the above steps, the scale and impurities in the cooling system of the tractor can be effectively removed to ensure the good working condition of the radiator, so as to ensure the normal operation of the engine and extend the service life.
