Quick Info.

About Hose:

The upper and lower hoses of the excavator radiator are part of the excavator cooling system. The cooling system is an important part of maintaining the normal operating temperature of the engine. Its main function is to absorb and dissipate the heat generated by the engine by circulating the coolant. The upper and lower hoses of the radiator are important pipes connecting the radiator and the engine. The upper and lower hoses of the radiator are usually made of materials such as rubber or silicone, which have good performances such as high temperature resistance, pressure resistance, and corrosion resistance. Its internal cavity absorbs the heat generated by the engine by circulating coolant, and transfers it to the radiator for heat dissipation, thereby maintaining the normal operating temperature of the engine. The design and manufacture of the upper and lower hoses of the radiator is very important, not only need to have good durability and durability, but also need to have good sealing performance to prevent coolant leakage. In addition, the upper and lower hoses of the radiator also need to have good bending performance to adapt to the space constraints inside the engine compartments of different excavators. In the daily use of the excavator, the upper and lower hoses of the radiator need regular inspection and maintenance to ensure their normal operation. Once the hose is found to be aging, cracked, leaking, etc., it needs to be replaced in time to avoid damage to the engine.
