The dismantling and maintenance of the cooling system of the hydraulic excavator is as follows:
1 radiator strong cleaning agent
The strong cleaning agent of the radiator can remove the dirt, scale and rust in the radiator cylinder head and the cylinder body water jacket, and can remove the accumulated grease and glial layer in the cooling system. It has a safe and effective cleaning ability.
Use strong cleaning agent, generally should be cleaned once every half a year. When cleaning, start the engine to normal temperature and extinguish the heat in the radiator according to the proportion of 355mL / 5-20L coolant in each bottle. Starting the engine, running 20-30min at normal temperature, the thermostat should keep the full opening position at the highest working point, ensure the large circulation of the coolant and clean the powder. Heat. After cleaning, the engine is extinguished, the cooling cleaning agent is released, and the cooling system is rinsed with clean water until the released water has no rust and water scale. The cooling system can re normal work again. In order to protect the radiator, restrain the corrosion of the system and enhance the cooling performance, the radiator can be added to the radiator to prevent the heat sink. Corrosion protection agent. In order to prevent the cooling system from leaking coolant, a permanent water tank leak stopping agent can be added to the radiator.
2 radiator antirust protection agent
The radiator protection agent can protect the cooling system and prevent the pitting and cavitation of the radiator, the warm air radiator, the cylinder body and the cylinder head, and the water pump and other parts. The special buffer components added in the antirust protective agent can neutralize the acid material, thus prevent the acid corrosion of the components in the system, and play the role of protecting the water tank. The antirust protective agent can prevent the formation of the sediment and keep the balance of the pH value of the coolant. It can improve the quality of the antifreeze liquid, enhance the cooling effect of the coolant, and have no corrosion to the hose and metal parts in the cooling system.
3 radiator super cooling protector
The super cooling protective agent of the radiator can enhance the cooling effect of the engine at high temperature, prevent the boiling of the water tank, prevent the foam in the water tank, prevent the air in the water cooling system and enhance the cooling effect. It can prevent the rust and scaling in the cooling system, inhibit the pitting and cavitation of the aluminum parts, prolong the service life of the radiator, and cold cooling. However, the hose and metal parts in the system have no corrosion.
4 permanent radiator leakage agent
The permanent radiator leakage agent consists of refined fiber, curing agent, antirust preservative, buffer and anti foam components. It can quickly stop the leakage and leakage of the radiator, warm air radiator, cylinder and cylinder cover water jacket, water pump, water seal and other parts in the cooling system. The leakage composition is superfine fiber and will not block the radiator. The pipeline has corrosion protection and anticorrosive effect, and can greatly extend the service life of the radiator. It has no corrosion effect on the hoses and metal parts in the cooling system.
