In Situ Balancing Services

Balancing is the process by which the mass distribution of a rotor is checked and, if necessary, adjusted to ensure that the residual unbalance or the vibrations of the journals/bearing supports and/or forces at the bearings are within specified limits.

Many rotors are balanced in specially designed balancing facilities prior to installation into their bearings on site. However, if remedial work is carried out locally or a balancing machine is not available, it is becoming increasingly common to balance the rotor in situ.

The aim of balancing is to reduce the vibration level at the rotational frequency of a rotating machine.

This procedure involves improving the distribution of rotor masses so as to reduce the eccentricity of the centre of gravity and thereby the resulting centrifugal forces. Generally, unbalance is corrected by adding or removing compensating masses to the rotor at prescribed locations in order to counter the effect of the initial unbalance.

On site balancing procedure

The balancing procedure involves testing the effect of masses on the balancing planes defined by us (flange of a wheel, fan blades, predicted balancing holes or slopes, etc.) in order to determine the number and location of the correction masses using our calculation software.

This procedure reduces production losses on site as the machine does not need to be disassembled.

In-Situ Balancing can be performed in Single Plane & Two Planes depending on the Job.
