Working principle： Expansion and contraction driven: The constant temperature valve mainly operates based on the principle of thermal expansion and contraction. Special expansion temperature-sensitive paraffin wax and other components are usually used as the temperature sensing elements. When the oil temperature rises to the melting point of the paraffin wax, the wax expands significantly, generating a large force that pushes the push rod, causing the valve core to move and opening the valve; when the oil temperature drops, the paraffin wax contracts due to the cold, and under the spring rebound effect, the valve core resets, closing or reducing the valve opening. Oil passage control: The expansion and contraction of the valve core is used to adjust the changes in the oil passage between the valve body and the housing, thereby controlling the proportion of lubricating oil entering the oil cooler. When the oil temperature is lower than the set value, the valve closes or the opening degree decreases, and the lubricating oil directly returns from the oil-gas tank to the main unit, achieving rapid heating; when the oil temperature is higher than the set value, the valve opens, allowing the lubricating oil to enter the cooler for cooling, and the cooled lubricating oil returns to the main unit, thereby ensuring that the rotor temperature remains within the set range.

Common Faults and Maintenance of 1635630500 Electromagnetic Valves in Atlas Copco Air Compressors Common faults of electromagnetic valves include coil burnout , valve core sticking , and aging of sealing components. During daily maintenance, the following points should be noted:Regularly check if the connection terminals are loose to avoid poor contact;Keep the valve body clean to prevent impurities from entering the valve core;When there is abnormal operation, it is recommended to replace the original electromagnetic valve to ensure performance compatibility. When replacing, pay attention to the consistency of voltage specifications and interface dimensions.

Atlas Copco CD5-22 Control Valve Maintenance and Precautions Regular Inspection: Regularly check if the valve has any air leakage, jamming or pressure adjustment failure. If abnormal pressure fluctuations or slow response are detected, it may be due to aging internal seals or blockage by impurities. Cleaning and Replacement: During maintenance, the valve body can be disassembled (requiring professional operation). Clean the internal valve core and valve seat, replace the aged seals; if the valve core is severely worn, it is recommended to replace the control valve as a whole to ensure performance. Parameter Matching: When replacing, confirm that the pressure adjustment range, interface size of the new valve match the original system, to avoid control failure due to incompatible specifications.

Key Points for Bolt Installation and Maintenance of Atlas Copco Pre-tightening Torque: Appropriate torque should be applied according to the bolt's strength grade and connection requirements . Excessive torque can cause the bolt to break, while insufficient torque may result in poor sealing or loosening. Surface Treatment: The bolt surface is usually galvanized, phosphated , or oxidized . Before installation, check the surface for rust or damage. Cooperation Precision: The cooperation between the bolt and the nut or the bolt hole must comply with standards . Avoid overly loose or overly tight threads. Regular Inspection: After the air compressor has been running for a period of time, check if the bolts are loose. If rust, deformation, or fracture is found, replace the bolts of the same specification and strength in a timely manner.

Choosing the Atlas Copco 8000 hour service package is an important measure to ensure the long-term and efficient operation of the compressor. It is particularly suitable for industries that require continuous production (such as manufacturing and energy industries), and through regular maintenance, it can minimize the overall maintenance cost of the equipment.
