What is the overall design of the tractor water cooling system?
When the tractor is working, the tractor engine parts come into contact with the high-temperature gas and are strongly heated, if not properly cooled, the internal combustion engine will overheat and the combustion will be abnormal, which will increase the friction and wear of the parts, affecting the power and durability of the internal combustion engine. The task is to ensure that the engine works at the optimum temperature. Do you know the general layout of the cooling system?

 

 

General layout of the cooling system

 

The general layout of the cooling system mainly considers two aspects, one is the air circulation system, and the other is the coolant circulation system. In the design, it is necessary to improve the air intake coefficient and the heat dissipation capacity in the coolant circulation.

1. Radiator arrangement

Tractor radiators generally use a heavy-flow water structure. The strength of the radiator and the reliability of the suspension are good. The cross-flow water structure radiator can make full use of limited space to maximize the windward area of the radiator. Such as garden tractors, greenhouse tractors, etc.

 

 

2. Wind shield layout

The function of the air hood is to ensure the amount of air generated by the fan. All the air flows through the radiator to improve the efficiency of the fan. The efficiency of the air hood is particularly significant for low-speed high-power fans. The smaller the mirror gap between the fan and the air hood, the greater the efficiency of the fan. However, if the clearance is too small, the tractor will cause interference between the fan and the air guard due to vibration during driving. The gap between the fan and the air guard is generally controlled to 15 ~ 25 mm to increase the flow and reduce the back pressure.

 

 

3. Fan arrangement

The size of the fan diameter and the shape of the radiator are coordinated. When the conditions permit, the diameter of the fan can be increased and the speed of the fan can be reduced to achieve the purpose of reducing power consumption and noise.

4. Thermostat arrangement

At present, the thermostats applied to the engines supporting tractors all use wax decorated rod body thermostats. When the cooling water temperature rises, the spicy expansion thermostat turns on and the cooling water flows through the radiator for a large cycle. When the cooling water temperature decreases, the spicy volume decreases. Small cycle. Thermostat is generally arranged at the outlet of the engine.

 

 

5. Front hood arrangement

Due to the harsh operating environment of the tractor, especially the return of straw to the field, weed debris flying around, it is easy to block the radiator. Therefore, the design and layout of the front hood is very important. It should be noted that the area of static wind should be large enough. It can well filter out large impurities in the cooling air, can form a good seal with the periphery of the radiator, and prevent hot air from flowing back.
