How to avoid high temperature when working with used excavators in summer
When using a used excavator in summer, in order to avoid high temperature problems, measures can be taken from the following aspects:
Do daily inspection and maintenance
Check the cooling system: Before the summer comes, the excavator’s radiator should be fully inspected. Clean the dust, debris and oil on the surface of the radiator to prevent accumulation and affect the cooling effect. At the same time, check whether the radiator’s water pipe is damaged or leaking. If there is a problem, replace the water pipe or repair the radiator in time.
Ensure the normal operation of the fan: The fan is an important component for excavator heat dissipation. Check whether the fan blades are damaged or deformed, and whether the fan’s drive belt is loose. If the blades are damaged, they need to be replaced in time; if the belt is loose, adjust the tension to ensure that the fan can run at a normal speed and effectively take away the heat.
Check the coolant: Check the coolant level regularly to ensure that the level is within the normal range. If the coolant is insufficient, add it in time. At the same time, check the quality of the coolant. If the coolant is found to be deteriorating or turbid, the coolant should be completely replaced to ensure its good heat dissipation performance.
Reasonable use and operation
Avoid long-term full-load operation: Try to avoid letting the used excavator work at full load or high load for a long time, because in this case the engine and hydraulic system will generate a lot of heat, which can easily lead to overheating. You can arrange work breaks appropriately to give the equipment time to dissipate heat.
Maintain a good ventilation environment: When the excavator is working, ensure that there is good ventilation around it. Avoid working in narrow, closed or poorly ventilated places to avoid heat accumulation. At the same time, open the hood or vents of the excavator to enhance air circulation and help dissipate heat.
Choose the right working time: Try to avoid high-intensity work during the high temperature period at noon. You can choose to work in relatively low temperature periods such as early morning or evening. This can reduce the operating time of the equipment in a high temperature environment and reduce the risk of overheating.
Monitoring and adjustment
Install temperature monitoring devices: Temperature monitoring devices can be installed on key parts of the excavator, such as the engine and hydraulic oil tank, to monitor the temperature changes of the equipment in real time. When the temperature exceeds the normal range, take timely measures to adjust it, such as stopping the machine for heat dissipation or checking the cause of the fault.
Pay attention to oil temperature and water temperature: During the operation of the excavator, pay close attention to the oil temperature gauge and water temperature gauge on the dashboard. Under normal circumstances, the engine water temperature should be maintained at 80-95℃, and the hydraulic oil temperature should be 50-80℃. If the temperature is found to be too high, stop working immediately, find the cause and deal with it.
Optimize equipment performance
Cleaning the engine compartment: Regularly clean the debris and dust in the engine compartment and keep the area around the engine clean. This helps the engine to dissipate heat better and avoid the accumulation of debris that prevents heat from being dissipated.
Upgrade heat dissipation components: If the heat dissipation performance of the second-hand excavator is poor, you can consider upgrading the heat dissipation components. For example, replace the high-efficiency radiator, increase the fan size or increase the fan speed to enhance the heat dissipation effect. However, during the upgrade process, ensure that the new components are compatible with the equipment and will not have adverse effects on other systems.
