China oil coalescing filters Manufacturer, Supplier, Factory

As an air compressor manufacturer, we often receive inquiries from customers. The company wants to purchase a batch of air compressors but doesn’t know how to choose or how to make reference. Here we summarize for you how to choose a suitable air compressor in general.

Compressors operate in many different types of environment, affecting the inlet air. Impurities, such as dust particles, are mostly invisible to the naked eye. But they can cause damage to the compressor element, reducing its efficiency or even causing failure. They can also make the lubricant age faster and disrupt its capacity to protect metal components.

Advantages of Original Factory Bearings Precise Matching: Atlas Copco original factory bearings are precisely matched with the design parameters of the equipment (such as speed, load, and clearance), which can maximize the performance of the unit and prevent early failures caused by size or performance mismatch. Quality Control: Using high-quality bearing steel (such as GCr15SiMn), they undergo strict heat treatment and precise processing to ensure wear resistance, stability, and service life (typically designed for a service life of 20,000 - 40,000 hours). Certification Compliance: Compliant with international standards such as ISO and CE, and passing Atlas Copco's own rigorous tests (such as vibration and temperature cycling tests), meeting the requirements of industrial-level continuous operation.

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.

Maintenance precautions for the load reduction device kit of Atlas Copco air compressors: Regularly clean the internal components of the load reducer to prevent the accumulation of oil and impurities, which could cause valve sticking or malfunction. Check the integrity of the seals and replace aging parts in time to avoid pressure control accuracy being affected by leakage. During commissioning, calibrate the pressure setting value according to the equipment manual to ensure accurate loading/unloading switching and avoid frequent start-stop or excessive pressure fluctuations.

Maintenance for the non-driven side motor components of Atlas Copco oil-injected screw compressors Regular inspection Observe whether there is oil leakage or seepage at the non-driven side end cover ， check for abnormal temperature rise， and use a sound detector to determine if there is any abnormal noise. Check the tightness of the end cover bolts to ensure reliable sealing. Bear maintenance Replace the bearing lubricating grease according to the cycle specified in the motor manual， clean the bearing chamber， and avoid mixing new and old lubricating grease. When replacing the bearings， ensure the model is matched， and install them using heat fitting or special tools to avoid damaging the bearings by knocking. Sensor calibration Regularly calibrate the temperature sensor to ensure detection accuracy； check if the connection terminals are oxidized or loose， and clean or tighten them if necessary.
