Turbine balancing machine BS-44-8000S

• Minimum achievable residual unbalance: 0.25 g*mm/kg.
• Unbalance reduction of up to 95% in a single run.
• Highest measurement linearity across all speed ranges and unbalance levels.
• Stands with 2 bearing blocks each, mounted on hardened and ground rail guides, providing more than a 12-fold safety margin for strength while allowing easy manual movement of the stand without any tools or mechanisms.
• Roller blocks feature V-shaped tooling, allowing for balancing rotors in their own bearings.
• Special tooling for balancing rotors with a short distance between support journals.
• Air pressure adjustment, pressure gauge, and the belt tensioning system control lever are combined into a single unit.
• Record-fast changeover from one rotor size to another.
• Durable support rollers with a surface hardness of 60 HRC on SKF bearings.
• Ability to install the machines on low-quality, uneven surfaces and freely move the machine, utilizing the "Machine to Rotor" approach.
• An excellent, time-tested design refined over years of manufacturing, incorporating extensive operational experience across all industries and requiring minimal maintenance.
• Unmatched versatility.
• Quick and easy to master.
• High-quality European industrial hardware — all handles. Virtually no tools needed for setup and operation.
• Reliable, rigid, and vibration-damping bed with a non-slip coating.
• Capability to balance rotors with a high initial unbalance.
• Convenient and practical adjustable cradles/jacks for smoothly transferring the rotor's weight onto the machine's rollers.
• An asynchronous frequency-controlled drive provides smooth, stepless speed variation and extensive options for selecting acceleration/deceleration modes.

The "R-Bal V3.9" software, like the hardware, is developed by "PK Robals" LLC and is continuously improved. It features a simple, intuitive interface.

Software

Select the configuration of the rotor to be balanced based on the location of the correction planes relative to the supports (between supports, overhung, double overhung, to the left or right of supports). Perform dynamic balancing in multiple planes simultaneously or in a single plane. Convert imbalance from one set of planes to another, and from one correction radius to another. Perform manual or automatic rotation of the rotor to a required angle, with the current position displayed on the screen. Automatically generate a dynamic balancing report. Set the number of signal averages based on the required balancing accuracy.

Calculate the permissible imbalance level based on known values of rotor mass and maximum operating speed. Set tolerances in various units (g*mm, g*cm, g*mm/kg, mm/s, µm). Perform a rotor run-up (rotor spinning to align the axis). Measure the amplitude during coast-down (run-out). Use special correction modes (drilling, milling); the program calculates the number of holes required for imbalance correction. Monitor rotation speed with an accuracy of 0.1 RPM and alert the operator of deviations from the initially set parameters.
