China Adsorption Dryer Silencer Manufacturer, Supplier, Factory

Atlas Copco Stationary Compressors enjoy a high reputation in the industrial field. The reason why they are highly praised worldwide is mainly due to their long-term accumulation and outstanding advantages in technological innovation, reliability, energy efficiency performance and customer service.

Key points for replacement and installation Shut down the equipment, release pressure and cool down to normal temperature. Close the inlet / return oil valves to prevent hot oil from spilling out. Record the path of the pipeline and the sequence of the joints, and keep the identification of the old parts. Clean the interfaces and installation surfaces. Replace the O-ring / sealing parts if necessary. Tighten the joints according to the specified torque; avoid excessive bending and stretching of the rubber hose; firmly fix the rigid pipe to prevent vibration wear. Before starting the equipment, check the oil level and sealing performance. After operation, recheck the pressure drop and leakage.

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.

First separation: The oil-gas mixture containing various-sized oil droplets, which comes out from the exhaust port of the air compressor main unit, enters the oil-gas tank. Most of the oil in the oil-gas mixture falls to the bottom of the tank under the action of centrifugal force and gravity. Second separation: The compressed air containing oil mist passes through the micrometer and fiberglass filter material layers of the oil-gas separation filter element for secondary separation. The oil particles undergo mechanisms such as diffusion, direct interception, and inertial collision aggregation, causing the suspended oil particles in the compressed air to quickly coalesce into large oil droplets. Under the action of gravity, the oil gathers at the bottom of the oil separation element and returns to the main lubricating oil system through the bottom concave area of the secondary return oil pipe inlet, thereby enabling the air compressor to discharge more pure and oil-free compressed air.

The oil filter element of Atlas Copco air compressors (Common Problems and Failure Causes) The filter element gets clogged prematurely Reasons: Excessive environmental dust (unfiltered intake air), excessive oil addition or mixing of different brand oils leading to emulsification, increased internal wear . Treatment: Improve environmental cleanliness, standardize oil usage, inspect worn components. Poor filtering effect Reasons: Using inferior filter elements , seal ring not properly aligned during installation , bypass valve always open. Treatment: Select original factory or high-quality aftermarket filter elements, ensure proper installation sealing, regularly check bypass valve function. Filter element rupture Reasons: Installation too tight, abnormal system pressure increase, insufficient strength of filter element material. Treatment: Standardize installation torque, check oil pressure control system, replace with qualified filter element.
