Atlas Copco Air Compressor Shaft Sleeve Oil Seal Kit C55 Oil Shaft - Importance Although the shaft sleeve oil seal kit is a small component, it directly affects the operating cost and reliability of the compressor: Leakage will lead to increased lubricant consumption, environmental dirtiness, and even serious faults such as bearing wear of the main unit and rotor sintering due to lack of oil. It is recommended to replace it with the original Atlas Copco C55 kit to ensure the matching accuracy and sealing performance with the main unit.

Maintenance and Replacement Specifications: Regular Calibration: According to industry standards, safety valves need to be calibrated by professional institutions on a regular basis (typically once a year) to ensure accurate pressure setting and reliable operation; Replacement Timing: If there is valve body leakage, malfunction, or if the calibration is不合格， the original factory safety valve must be replaced immediately. Do not attempt to adjust or repair it yourself； Installation Considerations： During replacement， ensure that the system is depressurized， the installation direction is correct (usually the valve body has a medium flow direction arrow)， the interface is well sealed， and do not install it in reverse or block the exhaust port.

Fault and Replacement Suggestions: If the check valve experiences leakage, sticking, or fails to close completely, it may result in decreased system pressure, increased energy consumption, or reverse rotation of the main unit. Suggestion: Regularly check the sealing performance of the valves (this can be determined through pressure retention tests); When a fault is detected, replace the entire original equipment set (instead of just replacing individual components) to ensure the compatibility of all components; When replacing, clean the pipe interface, tighten according to the specified torque, and avoid leakage caused by improper installation.

As a high-efficiency air compression equipment, the core working principle of a rotary screw air compressor is through two carefully designed rotors - a male rotor (male rotor) and a concave rotor (female rotor) - inside the casing.

I. Working Principle The safety valve is designed based on the principle of force balance. It mainly consists of a valve seat, a valve core, a spring, and a regulating mechanism. When the system pressure exceeds the spring's preload force, the valve core is pushed up, and the medium (compressed air) is discharged; when the pressure drops to the return seat pressure, the spring pushes the valve core back to its original position, closing the valve. Key parameters: Opening pressure (set pressure): The pressure at which the valve begins to open, usually 1.05 to 1.1 times the working pressure. Emission pressure: The pressure when the valve reaches its maximum opening height, generally ≤ 1.1 times the opening pressure. Return seat pressure: The pressure when the valve is closed, usually 10% to 15% lower than the opening pressure. Sealing pressure: The maximum pressure at which the valve maintains sealing, generally 90% of the opening pressure.

Maintenance and replacement suggestions for stainless steel gear in Atlas Copco screw air compressor: Regularly check the meshing condition, tooth surface wear, and axial clearance of the gears. If tooth surface peeling, cracks, excessive wear, or abnormal noise are found, they should be replaced in a timely manner to avoid more serious transmission system failures. During replacement, it is recommended to select the stainless steel gear made by Atlas Copco, so as to ensure the matching between the material, accuracy and the whole machine, and ensure the stability and efficiency of the transmission system after replacement. The installation process needs to be operated by professional technicians, strictly following the equipment manual specifications to ensure correct gear meshing and firm fixation, and to avoid early damage caused by improper installation.
