Under the conditions of high temperature and high humidity in summer, the operating load of the oxygen booster machine significantly increases, resulting in a decline in equipment heat dissipation efficiency and accelerated aging of components. Problems such as overheating shutdown, abnormal pressure, seal failure, and pipeline faults may occur. Moreover, the special property of the oxygen medium, which is flammable and explosive, greatly increases the operational safety risks of the equipment under high-temperature conditions.
In high-temperature environments, equipment cooling is the core focus of maintenance. It is necessary to ensure that the ventilation and cooling conditions of the equipment's operating environment meet the standards throughout the process, and to prevent high-temperature failures from occurring at the source.
1. Strictly regulate the placement environment of the equipment. The oxygen booster machine must be placed in a cool and ventilated area without direct sunlight exposure. It is strictly prohibited to operate it in a place that is exposed to long-term sunlight or in a confined and narrow space. A cooling space of no less than 0.8 meters should be reserved around the equipment. The top should be free from obstructions and clutter, and no obstructions or blockages that could impede the cooling air ducts or cooling fans should be allowed. It is forbidden to place the equipment in corner areas, behind cabinets, or beside material piles, where there are ventilation dead zones.
2. Optimize the ventilation conditions of the site. During high-temperature periods (environmental temperature ≥ 35℃), the workshop ventilation fans, exhaust fans, air conditioners, etc. need to be turned on to cool down, ensuring air circulation and controlling the equipment operating environment temperature within the rated working temperature range of the equipment to avoid the combined effect of high environmental temperature and equipment operating temperature rise, which could cause the equipment body to overheat and trigger alarms or shut down.
3. Before and after each shift, clean the dust, fluff, and oil stains adhering to the equipment body, heat dissipation plates, and heat dissipation vents. During hot weather, the accumulation of dust will directly block the heat dissipation channels, significantly reducing the heat dissipation efficiency. Cleaning should be done using clean, oil-free rags and dry compressed air for blowing. It is strictly prohibited to use cleaning agents containing oil or flammable and explosive substances, and it is necessary to ensure that oil stains do not come into contact with oxygen equipment to avoid safety hazards.
Next is the maintenance of the cooling system. The cooling system is the core for the stable operation of high-temperature equipment, and it requires daily specialized inspection and maintenance. Regularly check the coolant level and water quality to ensure that the level is within the standard scale range, without water shortage, turbidity, or deterioration. During high-temperature periods, preferentially use the high-temperature-specific coolant suitable for the equipment, and avoid using inferior coolant. Check the operation status of the cooling pump and the cooling fan, confirm that the fan speed is normal, there is no jamming, and no abnormal noise. The water supply of the pump should be smooth, without leakage or blockage, to ensure efficient heat dissipation of the cooling circulation system. Also, maintain the filtration and intake air system.
In high-temperature and dusty environments, the filter element is prone to clogging, so the maintenance frequency should be increased. Daily check the condition of the intake air filter. During hot weather, it is recommended to clean the filter element 1-2 times per week. Replace the filter element immediately when it becomes black, clogged, or damaged. Do not allow the equipment to operate without a filter element or with a failed filter element to avoid dust and impurities entering the equipment, damaging the precision components such as cylinders and pistons, resulting in decreased equipment efficiency and frequent failures. At the same time, check the smoothness of the intake air pipeline, without bends, blockages, or air leakage problems, to ensure stable intake air. Moreover, pay attention to the maintenance of the lubrication and sealing system.
High temperatures will accelerate the dilution and deterioration of the lubricating oil, and aggravate the aging and failure of the sealing components. Select the high-temperature-specific lubricating oil suitable for the equipment from the original factory, and strictly check the oil level and quality according to the cycle. If the oil shows signs of high-temperature deterioration such as thinning, blackening, turbidity, or foaming, replace it immediately to avoid excessive lubrication-induced component friction heating and accelerated wear. Daily check all sealing points, high-pressure connectors, and pipeline interfaces of the equipment to identify potential oxygen leakage or oil leakage hazards. Sealing rings, gaskets, and sealing packing that have aged due to high temperatures need to be replaced in time to prevent oxygen leakage accidents.
