ZL-220H Portable Field Balancer (Digital Display)

ZL-220H

Portable Field Balancer

Portable field balancing tool with digital display for single-plane and two-plane rotor balancing at rotational speed up to 8000r/min

Equipped with a digital display and support for speeds up to 8,000 r/min, these portable field balancers are capable of handling both single- and two-plane rotor balancing. They use an embedded computer platform that combines advanced digital and analog circuits with proprietary software, offering functions such as auto-tracking, digital filtering, and automatic gain control. Thanks to their design, the field balancing devices can deliver stable and accurate results whether used for very small parts or for larger rotors and can be applied across a wide range of balancing setups.

Applications

Used for balancing fans, motors, machine tool spindles, pumps, and grinding wheels. They can be used to both single-plane and two-plane balancing on-site, and can also be used with different balancing setups to correct rotor unbalance.

Balancing machines are instruments that indicate if a rotating component, such as a rotor or fan, rotates in an unbalanced manner. If the component wobbles or vibrates a lot, the balancing machine will point out the imbalance so it can be corrected. The importance of balancing is directly related to the longevity of the rotating component and how well the component functions.

Soft-bearing machines use flexible supports, making them sensitive to very small vibrations and suitable for lighter or smaller parts that require high accuracy. Hard-bearing balancing machines, on the other hand, use more rigid supports, so they are more suitable for larger and heavier rotors. Hard bearing balancing equipment may be less sensitive to tiny vibrations, but they are easier to set up and give reliable results across a wider range of workpieces.

Balancing machines are used to rotating parts such as motor rotors, impellers, fans, flywheels, clutches, gears, pulleys, and brake drums. By correcting unbalance, they help reduce vibration, extend service life, and keep production running more smoothly.

The frequency depends on usage intensity and operating environment. In most cases, calibration is recommended to calibrate balancing machines once a year, but for machines running under heavy workloads or harsher conditions, more frequent checks are advised to maintain precision.

Accuracy may be affected by operator handling, incorrect markings, or mismatched correction points. Technical issues such as damaged sensors, loose connections, or electronic failures can also play a role. Regular calibration and proper setup help keep results consistent.
