9K balancing machines: precision and power without compromise.

9K series balancing machines are highly versatile, so they are popular in the repair shops of gas, oil, power, metallurgical, and airline companies. Also machines of this series have a high accuracy (0,4 g*mm / kg), which makes them indispensable for balancing heavy parts with high demands on vibration.

The 9K machines consist of a bed, an electric drive, two vibration mounts with self-aligning roller blocks and resonant type pendulum suspensions, as well as “axial stops” when using a “belt drive”.

It is controlled by a “control panel” which is located in a separate electrical cabinet. The electrical cabinet also contains a “frequency converter” that allows smooth adjustment of the motor speed and protects the machine’s electrical equipment. The rotary motion from the motor to the workpiece can be transmitted by means of a belt “belt drive” or a cardan gear “axial drive”. The machine can be equipped with any or both of these drives, which will increase its functionality and reliability.

The 9K series machines balance these types of parts :

Inter-supported (load is distributed on both supports);
Single plane “disk” type (using a balancing mandrel);
Parts in their own bearings;
Cantilevered (option) ( the center of mass of the part is behind the supports).

The vibration level is determined by analyzing the signals from the vibration sensors located in the supports and the speed sensor which reads the rotor speed. The analysis is performed by the computing unit of the balancing system, which is located in the control cabinet. The balancing system is selected when ordering the machine. There are two ready variants: PB-02M based on modern microprocessor technology and PAK-1 hardware-software complex with industrial computer with touch screen. The balancing system can also be made to individual order, giving it any functions and properties for work.

Wide range of balancing rotors from 300 kg to 8 tons (depending on machine model);
No special foundation required for installation in the production hall;
The modular design of the MODULAR DESIGN machine enables its versatility to be upgraded by the addition of new balancing modules to balance rotors of all sizes and designs up to the rated load of the machine.
The possibility of installing jacks for shockless mounting of the part on the machine prevents damage to the balanced product or machine components caused by human error;
The design of the “axial stops” “MOVING ROLLER” and the belt tension adjustment mechanism of the “belt drive” minimize the possibility of errors in balancing providing a high quality detection of imbalance.

Functions of the hardware-software complex PAK-1:

Calculation of “permissible unbalance” The calculation of the “permissible unbalance,” the “test weight” and the “drilling depth” will eliminate the need to perform complex mathematical calculations and leave this to the computer;
Vector averaging improves accuracy and shortens the measurement cycle by combining the different unbalance vectors into a single “total vector”;
Accounting for tooling eccentricity will mathematically filter out tooling vibration from that of the part being balanced;
Recalculation of unbalance in constructional points (grooves, blades, etc.) if the unbalance correction places are limited by the rotor design;
Recalculation of unbalance to n correction planes allows unbalance to be divided into several correction planes, which in turn allows the use of a correction weight of smaller volume and mass;
Storing the balancing results in the computer memory and the possibility of printing them out solves disputable questions about the quality of the work performed.

PAK-1 BALANCING SYSTEM

Digital system is based on an industrial fanless computer with a touch screen and a measuring unit.
Setting up of the machine is performed by the 3 start-ups method with the use of calibration weights on the serial.
Calibration of the machine is made by the operator that allows to get the maximum sensitivity of the machine, and indemnify against annual payment for services in calibration of the machine.
Value calculation of permissible imbalances in the absence of technical documentation for the balancing product.
Value calculation of mass and correction weight are required for simplicity process to set up the machine at the new rotor.
Real time display: any defect of a rotor or hindrance it is visible immediately as oscillation of measurement result.

View of unbalance value in grams, gmm, gsm, gmm / kg, D, optionally.
