Summer Maintenance of Air Compressors

As summer arrives, high temperatures, humidity, and other weather characteristics pose significant challenges to the operation of air compressors. As the “powerhouse” in industrial production, the stable operation of air compressors is directly related to production efficiency. Therefore, it is particularly important to properly maintain air compressors during the summer. Below, we will explain the key points of summer maintenance for air compressors.

Pay Attention to the Cooling System to Ensure Efficient Heat Dissipation

• Regularly clean the cooler: The cooler is a key component for heat dissipation of the air compressor. In summer, there are more impurities such as dust and catkins in the air, which easily adhere to the cooling fins of the cooler and block the heat dissipation channels. Therefore, the cooler should be cleaned regularly. You can use compressed air to blow from the inside out, or rinse with clean water (be careful not to let water enter the motor and other components) to ensure that the cooling fins are clean and unobstructed, and improve heat dissipation efficiency.
• Check the coolant level and quality: For water-cooled air compressors, the coolant level should be checked frequently to ensure it is within the specified range. At the same time, observe the color and state of the coolant. If the coolant becomes turbid, contains impurities, or deteriorates, it should be replaced in time to avoid affecting the cooling effect. For air-cooled air compressors, check whether the fan is running normally, whether the fan blades are damaged or deformed, and whether the fan speed is normal to ensure that the fan can effectively dissipate heat.

Attach Importance to the Air Filter to Ensure Clean Intake Air

• Regularly replace the air filter: According to the user manual of the air compressor, regularly check the pollution degree of the air filter. If it is found that the surface of the filter element has a lot of dust and the air permeability is reduced, the new air filter should be replaced in time. In environments with poor air quality, the replacement cycle should be shortened.
• Check whether the filter element is installed tightly: When replacing the air filter, ensure that the filter element is installed in place and well sealed to prevent unfiltered air from entering the air compressor through the gaps.

Manage Oil Fluids Well to Maintain Lubrication Performance

• Regularly check the oil level and oil quality: Frequently check the oil level of the air compressor to ensure that the oil level is within the range specified by the oil gauge. At the same time, observe the color and viscosity of the oil. If the oil turns black, emulsifies, or has impurities, it indicates that the oil has deteriorated and should be replaced in time. When changing oil in summer, choose lubricating oil suitable for summer use with appropriate viscosity to ensure that it can maintain good lubrication performance at high temperatures.
• Check whether the oil circuit is unblocked: Regularly check whether the oil pipelines, valves, etc., are blocked or leaking, and ensure that the oil can circulate smoothly to provide sufficient lubrication for various components.

Pay Attention to the Motor and Electrical System to Prevent High-Temperature Hazards

• Check the motor operation status: In summer, pay close attention to the motor’s temperature, vibration, noise, etc. If the motor temperature is too high (exceeding the specified value), vibration is abnormal, or there is abnormal noise, stop the machine immediately for inspection, and restart it after troubleshooting. At the same time, keep the motor cooling fan and heat dissipation holes unobstructed to ensure good heat dissipation of the motor.
• Maintain the electrical system: Regularly check whether the electrical lines, connectors, switches, etc., of the air compressor are loose, aging, oxidized, etc. If problems are found, deal with them in time. Keep the electrical control cabinet dry and clean to prevent moisture and dust from damaging electrical components.

Strengthen Overall Inspection to Eliminate Hidden Dangers in Time

• Check pipelines and connectors: Check whether various pipelines of the air compressor (such as air intake pipes, exhaust pipes, oil pipes, etc.) are damaged or leaking, and whether the pipeline connectors are firm. If there are problems, repair or replace them in time.
• Pay attention to safety valves and pressure gauges: Regularly check whether safety valves and pressure gauges are sensitive and accurate to ensure they work normally within the specified pressure range. If safety valves are found to be inoperative or pressure gauges are inaccurate, they should be sent for inspection or replaced in time.
• Clean the equipment surface and surrounding environment: Keep the surface of the air compressor clean, and timely clean up debris, oil stains, etc., around the equipment to ensure good ventilation around the equipment and create a good operating environment for the air compressor.
