Balancing Machines for Fans, Blowers and Pumps

Type VHK11E

The VHK11E machine is designed to balance fans and blowers. Fan wheels may be designed as radial or axial wheels.

Special features

• Force-measuring, horizontal balancing machine in single-station or two-station design
  
• Low space requirement due to compact design
  
• High-precision measuring system with a resolution < 0.1 gmm and a wide speed range
  
• Orientation of the horizontal measuring axis selectable via rotary base plate (option)
  
• Smooth, ergonomically optimized sliding protection (weight-reduced) with magnetic guard lock
  
• Optimal operator support during balancing with current angle display and the help of blade counting
  
• Easy and fast setup of blade counting (fully automatic as an option)
  
• Short retooling times due to standardized interface (mechanical and electrical systems) for workpiece holding
  
• Intuitive operation of the machine (flat and clear operating structure)
  
• Free customization of parameters for the measuring process (unbalance, current, speed) for each type
  
• Free customization of parameters for the correction process (placing, removal, matching)
  
• Individual screens integrated in the stations (option)
  
• Service-friendly as all parts are accessible from the front
  
• Statistics package for optimizing the process (option)
  
• Automatic conversion of blade counting sensors
  
• Tandem design for short cycle time (t < 30 sec)

Application

• Balancing and testing of fans and blowers with AC, DC or EC motors

Type VVK11.2

The VVK11.2 machine is designed for vertical balancing of fan wheels in two planes.

Special features

• Force-measuring two-plane machine
  
• High-precision spindle with standardized interface for workpiece holding and automatic clamping/unclamping
  
• Compact operating panel with 19" touchscreen and control buttons
  
• Smooth pivot guard with automatic opening mechanism
  
• Broad range of clamping devices (manual or automatic clamping)
  
• Integrated runout measurement (tactile & optical) as option

Application

• Vertical balancing of fan wheels in two planes
  
• Measuring and correction of unbalance
  
• Measurement of axial runout
  
• Measurement of radial runout

Type S-17

The S-17 machine is designed for horizontal balancing of fans and blowers.

Special features

• Easy to use
  
• Simple loading and unloading through large access opening
  
• Low space requirement due to compact design
  
• Operator guidance with direct display of the unbalance correction on the monitor
  
• Permanent calibration
  
• High balancing precision
• Free programming of correction - positive correction by setting of clamps or negative correction by removal of material
• Adaption via HSK 100 clamping arbor or motor adapter
  
• Easy and fast retooling due to exchange adapter
• Balancing in one or two planes
• Blade scanning for simplified positioning during correction
  

Application

• Horizontal balancing of fans and blowers
  
• Balancing of rotors with internal or external drive

Type VVK41E

The VVK41E machine is designed for vertical balancing of large fans and blowers with radial or axial design and internal or external drives.

Special features

• Easy to use
  
• Operator guidance with direct display of the unbalance correction on the monitor
  
• Permanent calibration
  
• High balancing precision
  
• Low space requirement due to compact design
  
• Easy and fast retooling due to exchange adapter
  
• Simple loading and unloading through large access opening
  
• Blade scanning for simplified positioning during correction
  
• Complete testing sequences (current, speed, unbalance) freely programmable
  
• Free selection of the correction method - positive correction by setting clamps or negative correction by removal of material
  
• Design as mono or tandem machine
• Balancing in one or two planes
• Tandem machine design with overlapping cycle for significant cycle time reduction

Application

• Vertical balancing of large fans and blowers in radial or axial design
  
• Balancing self-driven fans or fans that require external drive

Type NVW-B

The NVW-B is a vertical soft-bearing single-plane balancing machine designed to measure and correct unbalance of pump rotors in serial production. Unbalance correction may be performed by axial drilling or milling in the cover plate.

Special features
