The underlying reason why the skid steer loader's temperature "explodes"

Analysis of the causes of engine overheating

As the power core of the skid steer loader, the working state of the engine directly affects the temperature of the equipment. The "reasons for overheating of the skid steer loader engine" are relatively complicated. First, air filter blockage is a common factor. When the air filter accumulates too much dust, the amount of air entering the engine is reduced, resulting in incomplete fuel combustion, engine power reduction, and excessive heat generation. According to statistics, about [X]% of engine overheating problems are related to air filter blockage. Secondly, cooling system failures cannot be ignored. Insufficient coolant cannot effectively take away the heat generated by the engine, which can easily cause the engine temperature to rise sharply. Damaged cooling water pumps cannot ensure the normal circulation of coolant, which will also lead to poor heat dissipation. In addition, if the thermostat fails, the coolant circulation path cannot be adjusted according to the engine temperature. When the engine temperature rises, the large circulation cannot be opened in time, causing the engine to run at high temperature for a long time.

Troubleshooting of cooling system

The cooling system is the key line of defense to maintain the normal temperature of the skid loader, and its failure is an important reason for the temperature to "explode". "Troubleshooting of cooling system of skid loader" needs to start from many aspects, and excessive dust on the surface of the radiator is the first point to be checked. The engineering working environment is harsh, and dust and debris are easily attached to the surface of the radiator, hindering the heat dissipation. Scaling of the water channel inside the radiator will also reduce the heat dissipation efficiency of the coolant. Fan failure also affects the heat dissipation effect. If the fan belt is loose or broken, or the fan motor is damaged, the fan speed will be reduced or even stopped, and sufficient heat dissipation air volume cannot be formed. In addition, the air duct design of the cooling system is unreasonable, or there are foreign objects blocking the air duct, resulting in poor air flow, which will also seriously affect the heat dissipation performance.

Factors causing temperature rise in the hydraulic system

The hydraulic system plays a key role in the operation of the skid loader, but its abnormality can also cause temperature rise. There are many factors that cause the hydraulic system of skid loader to increase temperature, and hydraulic oil contamination is a major cause. Impurities and water mixed in the hydraulic oil will reduce the lubrication performance of the hydraulic oil, increase the friction between the hydraulic components, and generate a lot of heat. If the pressure of the hydraulic system is too high and exceeds the rated value, the load on the hydraulic pump, motor and other components will increase, which will also cause the oil temperature to rise. If the viscosity of the hydraulic oil is too high or too low, it will affect the working efficiency of the hydraulic system and generate too much heat. For example, in a low temperature environment, if the hydraulic oil of suitable viscosity is not replaced in time, the viscosity of the hydraulic oil is too high and the flow resistance is large, which will cause the oil temperature to rise rapidly.

Relationship between long-term high-load operation and temperature

Long-term high-load operation of skid loader is a common cause of temperature "explosion". "Long-term high-load operation of skid loader is closely related to temperature". When the equipment is continuously in a high-intensity working state, the engine, hydraulic system and other components are subjected to high pressure and high speed for a long time, and the heat generated far exceeds the heat dissipation capacity of the heat dissipation system. Taking continuous material handling operations as an example, as the operation time increases, the temperature of the equipment gradually increases. If the temperature exceeds the limit that the equipment can withstand, the temperature will "explode". Moreover, long-term high-load operation will accelerate the wear of various components, further affecting the performance of the equipment and forming a vicious cycle.

Impact of environmental factors on temperature

Environmental factors have an impact on the temperature of skid loader that cannot be ignored. "The impact of environmental factors on temperature of skid loader" is reflected in many aspects. In high temperature environment, it is more difficult for the equipment to dissipate heat. When the ambient temperature is close to or exceeds the normal operating temperature range of the equipment, the temperature difference between the cooling system and the external environment decreases, and the heat dissipation efficiency is greatly reduced. In the hot summer, the outdoor temperature is as high as [X]℃ or above, and the temperature of the skid loader is more likely to rise during operation. In addition, poor ventilation of the work site will also hinder the heat dissipation of the equipment. When working in a closed or semi-enclosed space, such as an indoor warehouse or underground parking lot, the air circulation is not smooth, and the heat generated by the equipment cannot be dissipated in time, resulting in a continuous accumulation of temperature.

The "explosion" of the skid loader temperature is the result of the combined effect of multiple factors. From the engine, cooling system, hydraulic system, to the intensity of work, environmental factors, etc., each link may cause abnormal temperature. Only by deeply understanding these underlying reasons can we take targeted measures in daily use and maintenance to prevent the occurrence of temperature "explosion" and ensure stable and efficient operation of the skid steer loader.
