Summer loader "high fever" warning! How to effectively cool down the cooling system

As the hot summer is coming, the frequency of loader use is often high, but its cooling system faces severe tests. Once there is a problem with the cooling system, the loader is prone to "high fever", resulting in a decline in equipment performance and even serious failures. Understanding the long-tail keywords related to the cooling system of summer loaders, such as "reasons of high temperature of loader engines in summer", "maintenance skills of loader cooling systems", "solutions for poor heat dissipation of loader water tanks", etc., will help machine owners better deal with this problem and ensure the normal operation of the equipment.

Causes of high temperature: interweaving of multiple factors

Environmental factors bear the brunt

Summer temperatures are generally high, and ambient temperatures often exceed 35°C, and even reach above 40°C in some extreme areas. When loaders operate in such a high temperature environment, the difficulty of heat dissipation increases significantly. The high temperature outside is like putting a "heat cover" on the loader. The cooling system not only has to dissipate the heat generated by the engine itself, but also has to resist the invasion of high temperature outside, making the load of the cooling system far exceed other seasons. For example, at the construction site of urban construction, the surrounding buildings are dense and the air circulation is poor. The hot air around the loader is difficult to dissipate quickly, which further aggravates the impact of high temperature on the equipment. This is an environmental factor that cannot be ignored in the "reasons of high temperature of loader engines in summer".

Engine heat generation increases significantly

In summer, loaders usually undertake heavy tasks, and the engine is in high-load operation for a long time. During the operation of the engine, fuel combustion generates a lot of heat, and as the intensity of the operation increases, the heat generation speed increases. Taking the loading and unloading of a large amount of sand and gravel as an example, the loader needs to start, accelerate, lift and unload frequently, and the engine speed continues to remain at a high level, and the heat generated per unit time is much more than under normal working conditions. This high-intensity work causes the temperature in the engine compartment to rise sharply, which puts extremely high demands on the heat dissipation capacity of the cooling system, becoming one of the key internal factors causing high temperature problems.

Problems with the cooling system itself

1. Dirt accumulation in the water tank: In daily operations of the loader, the surface of the water tank is very easy to absorb a lot of dust, soil and other impurities. After a long period of accumulation, these dirt will form a thick covering between the radiator fins, hindering the heat exchange between the air and the coolant in the radiator. It is like putting a "heat-insulating coat" on the radiator, and the heat cannot be dissipated in time, causing the coolant temperature to continue to rise. According to statistics, it is not uncommon for the heat dissipation efficiency to be reduced by 30% - 50% due to the dirt in the radiator. This is a common problem that needs to be solved in the "Solution to Poor Heat Dissipation of Loader Radiator".

2. Insufficient or deteriorated coolant: Some owners are not careful enough in daily inspections and fail to detect the loss of coolant in time, resulting in a low coolant level. When the coolant is insufficient, its ability to carry and dissipate engine heat is greatly reduced, which can easily cause high engine temperature. In addition, after long-term use, the coolant will oxidize and deteriorate, its boiling point will decrease, and its heat dissipation performance will deteriorate. Deteriorated coolant not only cannot effectively dissipate heat, but may also corrode the metal parts of the cooling system, further affecting the normal operation of the cooling system.

Efficient cooling strategy: all-round maintenance and optimization

Regular cleaning of the cooling system

1. External cleaning of the water tank: Regularly use a high-pressure water gun to rinse the outside of the water tank, and control the water pressure within an appropriate range to avoid damaging the heat sink. When flushing, it should be done from different angles to ensure that dust, dirt and other impurities on the surface of the water tank are completely removed. It is generally recommended to perform a comprehensive flush at least once a week. In a dusty working environment, the flushing frequency can be appropriately increased. This can effectively restore the heat dissipation capacity of the water tank and solve the problem of external dirt affecting heat dissipation in the "Solution to poor heat dissipation of the loader water tank".

2. Internal cleaning of the cooling system: The cooling system needs to be cleaned every once in a while. You can use a special cooling system cleaning agent, add it to the coolant in the prescribed proportion, let the engine run for a period of time, so that the cleaning agent can fully dissolve the internal scale, rust and other deposits. Then, drain the coolant and repeatedly flush the cooling system with clean water until the discharged water is clear. This operation helps to keep the internal pipes of the cooling system unobstructed, improve the circulation efficiency of the coolant, and enhance the heat dissipation effect. It is an important part of the "Maintenance and Maintenance Techniques for Loader Cooling Systems".

Check and replace coolant

1. Liquid level check: Before working every day, the owner should develop the habit of checking the coolant level. Use the liquid level scale on the coolant expansion tank to determine whether the coolant is sufficient. If the liquid level is below the minimum scale line, it is necessary to add coolant that meets the loader's use requirements in time. When adding, pay attention to the brand and model of the coolant, and try to use products of the same brand and specification to avoid chemical reactions caused by mixing different coolants and affecting the cooling effect.

2. Quality inspection and replacement: Regularly test the quality of the coolant, and use a coolant tester to measure its pH, freezing point and other indicators. Under normal circumstances, the service life of the coolant is 2-3 years. If the coolant is found to be deteriorated during testing, it should be replaced immediately. When replacing the coolant, be sure to completely drain the old coolant in the cooling system to prevent the residual old liquid from affecting the performance of the new coolant. This is a key step to ensure the normal operation of the cooling system, and is also closely related to the "Loader Cooling System Maintenance Tips".

Optimize ventilation and heat dissipation environment

1. Clean up debris in the engine compartment: Regularly clean up debris in the engine compartment, such as leaves, branches, plastic bags, etc. These debris will not only hinder air circulation, but may also cause fires in high temperature environments. At the same time, check whether the wiring harnesses, pipes, etc. in the engine compartment are arranged reasonably to avoid affecting air flow due to improper arrangement, and ensure that the air in the engine compartment can flow smoothly through the cooling system and take away heat.

2. Improve ventilation in the working environment: When conditions permit, try to choose a well-ventilated site for work. For example, in a large open-air construction site, reasonably plan the working area to avoid the loader working in a narrow and closed space for a long time. If the working environment cannot be changed, consider installing auxiliary ventilation equipment, such as fans, etc., to enhance air convection, reduce the ambient temperature around the loader, and create more favorable heat dissipation conditions for the cooling system, which is of positive significance for solving the environmental factors in "the cause of high temperature of loader engine in summer".
