The HP ELEMENT EXCHANGE KIT of Atlas Copco air compressors have extremely high requirements in terms of material, insulation performance, and temperature resistance, and must comply with relevant high-pressure electrical standards. During use, the following points should be noted: Regularly conduct insulation tests and functional verifications to prevent performance degradation due to aging or moisture absorption. When replacing components, select original factory or certified compatible parts to ensure compatibility with the equipment's high-pressure system and avoid potential safety hazards caused by substandard components. The maintenance operations must be carried out by professionals with high-voltage electrical qualifications and strictly follow safety procedures.

Quick conclusions and suggestions for Atlas Copco air compressors using ball bearings The original factory / joint design of four-point contact ball bearings on the oil-free main shaft ensure positioning accuracy and lifespan. The motor end uses protective bearings that are compatible with the frequency converter. Emphasize lubrication and grounding / insulation to reduce the risk of bearing current. Replace based on the machine nameplate and serial number as the standard, avoid blindly replacing based solely on the "universal replacement number".

Atlas Copco Air Compressor Oil Pipe Maintenance and Replacement Regular Inspection: It is necessary to regularly check whether the oil pipes have hardened, cracked, bulged, loose joints or leakage. Especially during the equipment maintenance period, key inspections should be conducted. Timely Replacement: If the oil pipes are found to be aging or damaged, they should be replaced immediately with oil pipes that meet the original factory specifications to avoid oil leakage causing the equipment to run without sufficient lubrication, resulting in severe faults such as excessive wear of the main unit and overheating.

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.
