excavator radiator

Maintenance method of excavator radiator: 1. Avoid hot air recirculation during construction The filler near the radiator is often called a "sponge". But it cannot replace any "sponge". The needs of the excavator are mainly to avoid the recirculation of hot air, so corrosion resistance, temperature resistance and air permeability must be insufficient. That is, when the cold air drawn in from the front of the excavator radiator rises in temperature and enters the rear of the radiator (engine compartment), it cannot return to the front of the excavator radiator. When the hot gas returns to the radiator, the heat dissipation of the system is reduced, the temperature of the oil and water increases, the engine does not work properly, and may be damaged prematurely. Therefore, when operating a small hydraulic excavator below 30,000, it is impossible to ignore the observation and correction of the "sponge" near the radiator, and it is necessary to replace a part in time.
