Horizontal balancing machine for rotors BS-44-1000H

• Minimum achievable residual imbalance of 0.1 g*mm/kg.
• Imbalance reduction of up to 95% in a single run.
• Highest linearity of readings across all speed ranges and imbalance levels.
• Imbalance determination without trial runs for most rotors.
• Stands with 2 rolling blocks each, mounted on hardened and ground rail guides, providing more than a 12-fold safety margin while allowing easy manual movement of the stand without any tools or mechanisms.
• Roller blocks and support cradles feature a V-shaped design, enabling the balancing of rotors in their own bearings.
• Overhung positioning of rollers both within the roller block and the possibility of external relocation to solve the most complex balancing tasks.
• Air pressure adjustment, pressure gauge, and the belt tension system control lever are combined into a single unit.
• Record-fast changeover from one rotor size to another.
• Easy balancing of overhung and double-overhung rotors, even with the center of gravity located outside the supports.
• Long-lasting support rollers with surface hardness of 60 HRC on SKF bearings.
• Excellent, time-tested design refined over years of production, incorporating vast operational experience across all industries and requiring minimal maintenance.
• Unsurpassed versatility.
• Quick learning curve.
• High-quality European industrial hardware—everything features hand-operated levers. Virtually no tools are needed for setup and operation.
• Reliable, rigid, and vibration-damping base with anti-slip coating.
• Capability to balance rotors with high initial imbalance.
• Convenient and practical adjustable support cradles/jacks for smooth transfer of the rotor's weight onto the machine rollers.
• An asynchronous frequency-controlled drive provides smooth, stepless speed variation and extensive options for selecting acceleration/deceleration modes.
• Simple and effective adjustment of the roller block height using the included ratchet wrench.

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.
