China Atlas Copco Industrial Air Compressor PM Kit Manufacturer, Supplier, Factory

The maintenance significance of the check valve stem adjustment kit for Atlas Copco ZT55-90 series air compressors Precise valve stem adjustment can ensure that the intake valve fully opens when loaded and fully closes when unloaded, directly affecting the volumetric efficiency and energy consumption of the compressor. Regular inspections can help detect valve stem wear or jamming issues in advance, avoiding unit shutdown or overload damage to core components due to failure of the intake valve. When choosing, it is recommended to prioritize the use of Atlas Copco original kit to ensure that the component size, material, and model fully match the ZT55-90 series, guaranteeing the adjustment effect and equipment operation reliability.

Usage and Maintenance Notes Strictly match the model Different series of air compressors (such as GA, GHS, ZR, etc.) require the use of corresponding model-specific oils. Mixing or using the wrong type may cause equipment damage and affect warranty. Regular replacement and inspection Replace according to the specified cycle in the equipment manual (synthetic oil usually has a longer cycle than mineral oil), and replace oil filters, air filters, etc. at the same time. Regularly test the oil quality (such as viscosity, moisture content, impurity content) to avoid failures caused by deteriorated oil. Storage and refilling The oil needs to be stored in a sealed manner in a cool and dry place to avoid contamination; when refilling, ensure that the tools are clean to prevent impurities from entering the oil circuit system.

Atlas Copco 2906041300，The drive shaft bearing of the Atlas Copco air compressor is a crucial component that integrates functions such as support, load-bearing, positioning, and drag reduction. Its normal operation is the foundation for ensuring the reliable, efficient, and long-lasting performance of the air compressor. Correct selection, reasonable configuration, and meticulous maintenance are the key to keeping this "heart" beating powerfully.

ATLAS COPCO 1621049600 Maintenance and Replacement: During regular maintenance of the air compressor, it is necessary to check the condition of the gaskets. If any deformation, aging, or damage is found, they should be replaced immediately; After disassembly, if the gasket has undergone plastic deformation (such as a metal gasket), even if it is not damaged, it is recommended to replace it to avoid repeated use leading to sealing failure; When replacing, it is necessary to use gaskets of the same specification and material as the original ones. It is prohibited to substitute with different types of gaskets (such as using a rubber gasket instead of a metal gasket). Although the air compressor gaskets are small components, they are crucial for the sealing performance of the system. Choosing the appropriate gaskets and correctly installing and maintaining them can effectively reduce leakage faults, reduce energy consumption, and extend the service life of the air compressor.

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.

Maintenance recommendations for the oil filter of Atlas Copco screw air compressors: Replacement cycle: Under normal operating conditions, replace the filter once every 2,000 - 3,000 hours. In harsh environments (such as high dust and high temperature), this period should be shortened to 1,500 hours. Synchronous operation: When replacing the filter element, also simultaneously discharge the settled oil at the bottom of the oil tank (containing a large amount of impurities) and refill the oil to the specified level. Selection requirements: It is necessary to select original factory or certified filter elements that match the compressor model to avoid equipment damage due to size mismatch or insufficient filtration accuracy. Effective maintenance of the oil filter can significantly reduce the wear rate of the screw main unit and is a key aspect of the daily maintenance of the compressor unit with low cost and high efficiency.
