Working principle of Weichai generator remote radiator cooling system

If the Weichai generator is installed below the plane, it is recommended to use a remote radiator for cooling because the space limits the use of the air duct. In the remote radiator cooling system, the radiator is separated from the engine, and the electric fan is used for heat dissipation. This system can be used as a fully enclosed unit for outdoor use, or it can be used as an open form for indoor installation.

When the radiator is installed more than 3 meters above the generator set, most engines require a separate water tank (components: high water tank, water storage tank, low water tank) and an electric water pump. The size of the branch water tank depends on the entire cooling system The capacity, that is, the total amount of pipes required plus the amount of cooling water. The cooling water is driven by an electric circulation pump, and circulates from the separate water tank through the radiator and the engine. Generally, the heat dissipation fan and water pump motor are powered by the generator set, and the load power required for this part should be included in the total generator set power.

When the Weichai generator is not in use, the water will flow from the radiator into the separate water tank, and when the unit is running, the separate water tank must have enough water to fill the entire cooling system and maintain sufficient cooling for a long time water. To ensure the effective circulation of the unit. Note on this system:

1. To prevent foreign substances from contaminating the cooling water agent;

2. The turbulence of the branch water tank can make the water oxidize

3. To avoid air being enclosed in the system, the pipeline should be equipped with ventilation holes;

4. Carry out proper water treatment to meet the water quality requirements of the engine;

5. To prevent water condensation and corrosion, the entire cooling water system must be added with coolant and preservatives as required;

6. The cooling water keeps flowing naturally in the water tank circulation system.
