Atlas Copco Thermostat: Core Function and Working Principle at 40 Degrees Celsius
Atlas Copco Temperature Monitoring and Regulation
This thermostat is typically installed in the oil cooling circuit or cooling system of the air compressor. When the lubricating oil temperature reaches 40 degrees Celsius, it triggers the corresponding control action. For example, it may turn on the cooling fan, activate the water-cooling valve, or adjust the oil flow path. By enhancing heat dissipation or adjusting the cooling intensity, it prevents the oil temperature from exceeding the limit (the normal operating oil temperature of an air compressor is typically between 80-95 degrees Celsius, and 40 degrees Celsius is usually the threshold for low-temperature startup or initial adjustment).
Atlas Copco Protection and Energy Saving Function
During the equipment startup phase, if the oil temperature is below 40 degrees Celsius, the thermostat may shut down the cooling system, allowing the lubricating oil to quickly warm up to the optimal working temperature (reducing the energy consumption increase and component wear caused by excessive viscosity at low temperatures); when the temperature rises above 40 degrees Celsius, it gradually activates the cooling device to maintain a stable temperature, avoiding system overheating.
Application Scenarios and Associated Systems
It is mainly adapted to the temperature control circuit of Atlas Copco oil-injected screw air compressors, especially in small and medium-sized units with temperature sensitivity or in specific operating conditions (such as low-temperature startup). It plays a role in these scenarios.
It usually works in conjunction with components such as coolers, fans, and solenoid valves to form a complete temperature control system, ensuring that the temperature of the lubricating oil and compressed air is within the ideal range, which not only guarantees the lubrication effect but also avoids accelerated aging of the oil due to high temperatures.
Common Faults and Maintenance of Atlas Copco
Temperature Sensing Abnormality
This may occur due to sensor aging or oil contamination, resulting in a discrepancy between the detected temperature and the actual temperature, causing the cooling system to start prematurely or fail to act as expected. Regular cleaning of the sensor probe is necessary, and calibration or replacement may be required when necessary.
Atlas Copco Valve Stuck
If the thermostat integrates a flow control valve, it may become stuck due to the accumulation of oil sludge or impurities, preventing normal switching. It is recommended to clean the temperature control circuit during the lubricating oil replacement cycle to avoid the influence of contaminants on the valve operation.
Atlas Copco Wiring Fault
Loose or oxidized wiring for temperature control signal transmission will cause the control instructions to fail. During daily inspections, ensure that the connection terminals are secure and free from rust.
