China 2906016500 ZR3 THROTTLE VLV MOUNTING KIT Manufacturer, Supplier, Factory

Common reference for the accessory numbers of the Atlas Copco WIS series pressure reducing valves: Some models may use the pressure reducing valve with the part number 2901126000 (which requires matching specific pressure parameters)

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. Heat dissipation maintenance

Replacement and Maintenance Recommendations: Replacement Cycle: Generally, replace once every 3,000 - 4,000 hours or annually (whichever comes first). In harsh environments, the cycle should be shortened; Replacement Indicators: If the oil content in the compressed air exceeds the standard (oil stains appear at the air inlet), or if the pressure difference between the separator inlet and outlet is too high (more than 0.8 - 1.0 bar), replace immediately; Installation Notes: During replacement, clean the interface, check the integrity of the sealing ring, and tighten according to the specified torque; after replacement, discharge the air inside the tank to ensure the system operates normally.

Structural composition Valve body: The main body that connects the oil circuit, usually having an oil inlet, a direct outlet, and an outlet for the cooler. Thermosensitive element: The core component, which expands or contracts with temperature changes. Spring: Cooperates with the thermosensitive element to control the opening and closing degree of the valve. Valve core / Valve rod: The actuating mechanism, which regulates the oil flow direction according to the signal from the thermosensitive element.

Atlas Copco also offers other types and specifications of lubricants, such as Roto Inject NDURANCE mineral oil-based compressor oil suitable for GA-GX rotary screw compressors.

Maintenance and replacement precautions for the pressure valves of Atlas Copco industrial air compressors: Regularly check the sealing performance and adjustment accuracy of the pressure valves. If there are problems such as excessive pressure fluctuations, leakage, or inability to relieve pressure, timely maintenance is required. When replacing, use original Atlas Copco parts to ensure compatibility with the compressor model and avoid system failures due to parameter mismatch. Maintenance or adjustment should be carried out by professional technicians. Follow the equipment manual specifications strictly to prevent safety risks caused by incorrect pressure settings.
