The rotor speed of industrial centrifugal compressors and screw compressors is generally 8,000-30,000 r/min. The impellers are made of thin-walled aluminum alloy or titanium alloy, and the requirement is G2.Level 5.Fuman Machinery Laser machine balancing Machine & It can precisely correct unbalance without damaging the blades, meeting the process requirements of the main engine manufacturer.
The speed range of compressors and expanders in the gas separation industry is large (3000- 60,000 r/min), and they are extremely sensitive to residual unbalance.Air separation equipment is required to operate stably for tens of thousands of hours or more. The balance quality directly affects the shutdown maintenance cycle.
The working speed of separation machinery (chemical centrifuges, screw centrifuges) is 1500-4500 r/min. The impellers are mostly made of stainless steel, and the drums have large diameters and heavy weights. It is recommended to perform overall machine balancing after assembly.The vertical disc type model is suitable for such large-sized parts.
Vacuum pumps and molecular pumps operate at extremely high speeds (some exceeding 60,000 r/min), and the geometric accuracy of turbine blades directly affects the vacuum degree.It is recommended to perform precise balancing in a clean environment. Slight eccentricity was detected in the soft-supported model.
Industrial transmission components (pulleys, gear shafts, couplings, bearing cages) are generally 500-3000 r/min, G6.Level 3 is sufficient for use.For large-batch transmission parts, it is recommended to achieve fully automatic double-sided balancing.
The impellers of water pumps (centrifugal pumps, axial flow pumps, and mixed flow pumps) fall under the general machinery category of rotor. It is recommended to perform rough balancing after casting/welding and before processing, and then perform fine balancing after installation onto the pump shaft.It is recommended that large water pumps be balanced on site.
The impeller of a multi-stage compressor has more stages and is heavier, making it more sensitive to residual imbalance.It is recommended to balance each grade separately and then conduct the overall machine balance after assembly. During the process, retain the data of each grade for failure analysis.
The working speed of the impellers of industrial centrifugal fans and axial flow fans in the power, metallurgy and cement industries is 1450-3000 r/min. During long-term operation, they become unbalanced due to wear, scaling and deformation.Fuman Machinery can simultaneously undertake on-board balancing and on-site balancing services.
The ventilation systems of tunnels and subways have high requirements for the reliability of fans. The impellers are prone to be forced to shut down for maintenance due to excessive vibration after long-term operation.Fuman Machinery offers full-cycle services from factory delivery to on-site rebalancing.
Fans in the HVAC and environmental protection dust removal fields have relatively low rotational speeds, but strict requirements are imposed on noise and lifespan.The Fuman vertical balancing machine covers such products, with a measurement range from 0.Full coverage from 5kg to 5000kg.
