Mobile balancing system " SCHENCK " for use anywhere in the world The balancing system is permanently installed in a 20" open-top container. The container is equipped with everything you need for balancing • Lighting • Metal base plate 12,000 kg as a base plate for accuracy • Compressor for working air supply distributed in the container • Compressed air connections. • A circumferential power strip • A tool cabinet equipped with tools • A hydraulic lifting device for aligning the container from the outside • In addition to a tarpaulin for the roof, the container also comes with movable roof segments made of sheet metal. • The container has a central plug through which the container can be connected can be supplied with the required 380V voltage. The system has been approved by Schenck and test protocols are available The basic version of this machine consists of an HM 40 U/BU. Additionally we offer a special add pair. Type HM 20 feet, which are easy to use can be exchanged for the HM 40 feet. With the HM 20 bases You can also accommodate small pump rotors in the machine. The advantages are: -only one machine base and final and belt drive with one electrical control (space-saving) -The machine is designed as a safety enclosure in a 20-inch open-topped Container installed. (space and cost saving) The HM 40/20 U/BU covers due to rotor weight, dimensions and Balancing tolerances cover a wide range of rotor types. This requires possibly also flexibility in speed compensation. That's why we have the machine together with an electric drive Squirrel cage motor with frequency converter for variable speed offered. The CAB 920 measuring device on offer is a computer-controlled high-end device and was specially developed to fulfill demanding balancing tasks. Data entry is extremely easy thanks to the “Easy Mode” and guides you Operator perfect. The unbalance is visualized using large Vector displays on a high-contrast TFT color monitor with touchscreen Function. The unique one runs on the integrated industrial PC CAB 920 balancing software and offers access to the balancing data for direct Printouts or via a PC network. CAB 920 can be replaced by additional Software packages can be adapted to specific needs. For quick and accurate determination of the angular position of the measured unbalance Rotor using a belt drive is the “angle indexing” software extension in the Both measuring devices are included in delivery. Upon reaching the correct The unbalance angle is displayed on the measuring unit. Due to the correction method (grinding on a larger area) the Vector information is an advantage.

The counter bearings are pivotable and do not get in the way to make loading and unloading the rotor easier. Each set consists of: - 1 x counter bearing with raw (negative bad bearing for overhanging rotors) - 1 x counter bearing with slider 1.7 2 axial thrust stops mounted on machine base Two axial thrust stops for mounting on the machine base for balancing large rotors in an overhanging position. 2.0 1 machine bed with roller chain and two T-slots for moving the feet simply along the machine base Total bed length consisting of 5000 mm 1 x 3000mm, 1 x 2000mm 3 1 measuring system with: Operating system Windows 10 loT Enterprise 2016 LTSB - Direct data entry without keyboard via touch screen display - Easy Mode for simplified data entry and result display - Display of the result via large vector meter and numerical displays - Workshop-tested industrial PC - Easy data export via front USB - Network capability - Optimized signal processing for high accuracy through Schenck MMD Digital filter - Intelligent self-diagnosis of the measuring electronics - Modular, service-friendly system design - Operation with Windows standard procedures - Measurement of dynamic, static and pair unbalance - Optimized menu functions - Rotorfile wizard - Ability to connect drawings or instructions to rotor files - User-level management with individual profiles - Numerous software modules available - mcl.

The rotor specific Calibration software improves the ability to take measurements of the bearing level to be transferred to the correction layers (plane separation). The rotor specific Calibration should be used when there is a large cross effect between Correction planes are determined by a small distance from each other are separated. Rotor specific calibration is also useful if the result is Rotor weight and balancing speed correspond to the weight-speed square Value (Wn2) of the machine approaches or slightly exceeds it, or if the rotor is deformed during balancing (e.g. fan blades with variable slope). Also balancing machines with offset roller bearings that Significantly influence the stiffness of the support bearing system, benefit from this Use of rotor-specific calibration. 4 1 final drive U2 Drive power 7.5 kW Balancing speed 1st gear 60 - 580 rpm Compensation speed 2nd gear 110-1120 rpm Drive shafts Drive Shaft 250 Nm, Drive Shaft 80 Nm 4.1.1 Rotor lock – final drive 4.2 1 belt drive BU 4/5 Drive power 7.5 kW Belt driven diameter 20 - 600 mm Balancing speeds based on a belt driven diameter of 100mm: 140 - 1460 rpm, 200 - 2000 rpm, 350 - 3640 rpm 4.3 1 Rotor lock – belt drive 5 1 Electric drive and control for variable balancing speed, consisting of: Control cabinet prepared for installing the measuring unit with: - Frequency converter for speed adjustment range 1:10 and energetic Recovery system - Operating devices and contactors
