Atlas Copco Air Compressor Intake Valve Maintenance Kit Set Composition (Typical Configuration)
Sealing Components: Include O-rings, sealing gaskets, valve seats, etc. The materials are mostly oil-resistant rubber (NBR) or fluororubber (FKM), used to replace aging and failed sealing parts to prevent air leakage.
Moving Components: Such as valve cores, pistons, springs, push rods, etc., used to repair problems caused by wear and jamming of the valve disc, ensuring the valve disc operates sensitively and the loading/unloading switching is smooth.
Wear Parts: Include bearings, bushings, gaskets, fixing bolts, etc., ensuring that all possible loss components that may affect performance can be replaced at one time during maintenance.
Special Lubricants: Some sets contain special lubricating grease for the intake valve, used for the maintenance of moving components, reducing friction resistance.
Functions and Effects
The intake valve is the core component controlling the air intake volume of the air compressor. It achieves loading (full-load operation) and unloading (idle operation) by adjusting the valve opening. The function of the maintenance kit is:
To solve the leakage problem caused by aging sealing components, avoiding insufficient loading pressure and increased energy consumption.
To repair wear or jamming of moving components, ensuring the valve disc responds sensitively and the loading/unloading switching is smooth.
To replace all wear parts comprehensively, extending the overall service life of the intake valve and reducing frequent failures.
Maintenance and Replacement Precautions
Maintenance Cycle: It is recommended to conduct maintenance every 8,000 - 16,000 hours or in conjunction with annual maintenance. If there are phenomena such as slow loading, unstable pressure, or un-reduced pressure during unloading, it is advisable to carry out maintenance in advance.
Installation Requirements:
When disassembling the intake valve, record the assembly sequence of the components to avoid incorrect reassembly.
Clean the inner cavity of the valve body, remove oil stains and carbon deposits, ensuring that there is no jamming after installing the new components.
Before replacing the sealing components, check if the installation slots are intact to avoid secondary leakage due to damaged slot bodies.
Original Equipment Advantage: The components of the original equipment maintenance kit have the same size and material as the intake valve design, ensuring that the repaired performance reaches the factory standard. Compared with scattered purchasing of spare parts, it is more reliable and can avoid rework due to compatibility issues.
