2989015900 Atlas Copco Screw Element / Screw Block by Reliable Supplier
1. Using the standard Atlas Copco profile (SAP), the rotor adopts a 4/6 tooth combination, and the rotor diameter is equal. Compared with the 5/6 tooth (Sigma) or 4/5 tooth (Cyclone) combination, the female rotor has higher rigidity, So it is not easy to deform, and the internal leakage loss is small.
2. SAP profile: due to compression force, it contacts the rear edge of the tooth side. The gap of the rotor seal line is small. The outlet hole at the exhaust end is small (small leak triangle). Small internal leakage and loss. Higher internal pressure ratio (10 bar). Improved efficiency, especially in 10 and 13-bar models, which have larger rotor diameters and low tip speeds.
3. Effective, reliable, and long-life oil seals and gas seals after more than 40 years of continuous improvement and the test of time. It is composed of oil seal C with reverse thread and two stainless steel gas seals B. These oil seals and air seals maintain a small gap with the shaft but do not contact, and their sealing efficiency, reliability, and life are far better than the general labyrinth seals or mechanical seals. There is a small leakage hole E between the oil seal and the gas seal, in case the seal is damaged, it can still provide compressed air.
4. Gearbox: It can reduce energy consumption and costs. The axial force generated by the gear offsets the axial force acting on the male rotor. Direct drive does not have this advantage.
5. Keep the temperature lower.
Atlas Copco Compressor Air End Features:
1. Adopt a 4/6 rotor tooth profile.
2. The gearbox is specially designed to reduce the axial force. Using original imported SKF bearings to ensure service life.
Product advantages: originally imported bearings to ensure the operating life of the host
Product parameters: profile line, using 4/6 teeth
CBN grinding wheel
CNC five-axis linkage rotor grinder
Atlas Copco Air End Maintenance Precautions:
1. Replace the special lubricating oil on time;
2. Regular main engine overhaul and maintenance to improve main engine efficiency;
3. Check whether the bearing coupling and other parts are in good condition before starting the new machine;
4. Pay attention to checking the steering when starting up or changing cables.
