China 1901902344 Atlas Copco Manufacturer, Supplier, Factory

The EWD75 air compressor electronic drainage valve maintenance kit is a component set specifically designed for the repair and maintenance of EWD75 type electronic drainage valves. Its purpose is to restore the normal function of the drainage valve, extend the service life of the equipment, and prevent the accumulation of moisture in the compressed air system due to the failure of the drainage valve.

Atlas Copco 2906073900,The air compressor maintenance package protects the design of the air compressor, reduces equipment wear, maintains stability and extends lifespan: The maintenance includes air filters, oil filters, and oil-gas separators, etc. Regularly remove impurities to prevent blockages and ensure proper temperature operation. 2230000800,Original factory parts maintenance can avoid performance degradation and equipment damage of original factory parts, reduce the risk of thermal shutdown, and extend the overall lifespan. The entire maintenance package has a lower price and can be purchased in bulk. It optimizes inventory management and reduces costs caused by downtime.

Maintenance precautions for Atlas Copco non-return valve assemblies Regularly inspect the wear condition of the seals. Replace them immediately if there is leakage. Clean the valve core and valve seat to prevent impurities from jamming and causing the valve core to fail to close properly. For spring-type non-return valves, check the elasticity of the spring to see if it has weakened. Replace it if necessary to ensure the sealing performance. When selecting non-return valve assemblies, match them according to the exhaust pressure, flow rate, medium characteristics, and pipe diameter of the air compressor to ensure that their pressure resistance level, flow capacity, and system requirements are consistent.

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.

Atlas Copco 2906084000，Regularly replacing wear-prone parts such as air filters and oil filters can prevent issues like insufficient air intake and overheating, thereby reducing unplanned downtime and lowering maintenance costs. By cleaning the pipelines, replacing lubricating oil and the three filters, wear can be effectively reduced, extending the overall lifespan of the air compressor. Inspecting key components such as solenoid valves and coolers ensures that pressure maintaining valves and protection differential pressure switches function properly, preventing overload or leakage risks. Using original factory parts can reduce energy consumption, simplify maintenance procedures, and minimize additional costs due to incompatible parts.

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.
