HZ-602 Industrial Control Measurement System
The measurement system is the core of the balancing machine. This
system uses the latest CPU computing chip, and then performs
operation to display the measurement data after signal
amplification, filtering, and analog-to-digital conversion. At the
same time, it also has the output of database, communication data
and control signal, including the connection of printer.
Human-machine dialogue interface, intuitive and simple operation,
suitable for display mode in industrial production environment.
After strict multi-level component screening, large-scale
electrical circuit manufacturing process, coupled with high and low
temperature aging tests, it can be suitable for balancing machines
to perform accurate
measurements in different environments.

Precautions
Installation of balancing machine
1. The compressive strength of the foundation concrete is ≥16MP,
the foundation uses No. 525 cement, and the secondary grouting uses
No. 625 cement.
2. The installation level of the machine is ≤0.2/1000. The machine
needs to be grouted twice after adjusting the level. When grouting,
it should be fully padded, and the anchor bolts should be tightened
after the foundation is completely dry.
3. For details, please refer to the foundation installation drawing
of HW-1000 type balancing machine

Purpose
An unbalanced rotor generates a pressure on its supporting
structure and the rotor itself during its rotation, and causes
vibration. Therefore, the dynamic balance of the rotor is very
necessary. The balancing machine is to check the dynamic balance of
the rotor in the rotating state. The function of dynamic balance
is:
● Improve the quality of the rotor and its components
● Reduce noise
● Reduce vibration
● Improve the trial life of supporting parts (bearings)
● Reduce user discomfort
● Reduce the power consumption of the product
Unbalance amount calculation
Where mper is the allowable unbalance:
M: represents the weight of the rotor, the unit is kg
G: represents the balance accuracy grade of the rotor, the unit is
mm/s
r : represents the correction radius of the rotor, the unit is mm
n: represents the speed of the rotor, the unit is rpm.
