How to choose the bearing of air compressor-screw air compressor manufacturers?

The overhaul of a conventional air compressor is largely the overhaul of bearings and rotating parts. The main reason is to replace the corresponding bearings and seals, and the repaired compressor head can also achieve the effect of approaching the new machine. Of course, the prerequisite for maintenance is that the compressor itself is fault-free. There is no obvious wear on the rotor and the inner cavity of the casing. Therefore, understanding the selection of compressor bearings has a strong guiding significance for compressor overhaul. KINGBULL screw air compressor manufacturers use Sweden SKF bearings.

What factors should be considered in the selection of compressor bearings?

The main factors that should be considered in the selection of bearings: due to different structural characteristics, bearings of various structural types can be adapted to different conditions of use, and designers can choose according to their own needs. Generally, the following main factors should be considered when selecting bearings. The load is the most important basis for selecting a bearing. Generally, the bearing should be selected according to the size, direction and nature of the load. Choose KINGBULL screw air compressor manufacturers, we use the best Sweden SKF bearings in air compressor for you.

Air compressor load size-screw air compressor manufacturers

In general, roller bearings have large load capacity due to line contact and are suitable for bearing large loads. Since the ball bearings are point-contacted, the bearing capacity is small, suitable for light and medium loads.

Currently, because of COVID-19, if your factory wants to resume work and production normally and safely, you may need gloves making machine, disinfection door, tunnel, backpack disinfectant sprayer, thermal fogger machine, blu ray anion nano spray gun to ensure safety. This year, many mask production line manufacturers and melt-blown cloth manufacturers have purchased our air compressors as supporting power machinery.

Air compressor load direction-screw air compressor manufacturers

Because the bearing of the compressor head is subjected to radial load and axial load. Therefore, angular contact ball bearings or tapered roller bearings are generally used. The bearing capacity of these two types of bearings increases with increasing contact angle. If the radial load is large and the axial load is small, deep groove ball bearings and cylindrical roller bearings with ribs on the inner and outer rings can also be used. If the axial load is large and the radial load is small, thrust angular contact ball bearings and thrust tapered roller bearings can be used.

Air compressor load nature

When there is impact load, roller bearings should be used. Due to the interaction force between the male and female rotors of the twin-screw air compressor, the reaction force of the compressed gas on the rotor, the compressor bearing must bear both radial and axial loads. At the moment when the air compressor starts, the starting torque is up to 3692 N · m, so roller bearings should be used. In addition, factors to be considered are axial travel performance, high-speed performance, self-aligning performance, allowable installation space, and ease of installation and dis-assembly.

In summary, the selection of the screw air compressor head bearing: the high-pressure end uses a tapered roller bearing as a thrust bearing, and the low-pressure end uses a cylindrical roller bearing with an inner ring as a support bearing. Contact KINGBULL screw air compressor manufacturers, we will be your ideal partner.
