Balancing Machines for Fans, Blowers and Pumps


Dynamic Vertical Balancing Machine for Fans in Air Conditioners (Automotive)

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
