Prime Field Service Millwrights highly skilled in dynamic balancing large rotors with precision
Prime Field Service Dynamic balancing services for your rotating equipment.
Millwrights are dynamically balancing large fan 2 planes.
Repair maintenance of small hydro electric plant required balance of the rotor.
Millwrights checking vibration signatures to determine corrective action to eliminate vibrations
Machine maintenance of rotary screw compressor rotor requiring dynamic balance completed by Prime Field Service millwrights
Prime Service millwrights completing the turbine rotor maintenance by dynamically balancing the rotor to precision requirements.
Large low pressure steam turbine rotor being set into our Balance stand for our balancing millwright team to dynamically balance.
We direct couple our Hydraulic drive unit to the rotor which also controls any axial thrusting.
The rollers on the balance stand have a large surface/contact area, this prevent any marring or marking of the bearing journal areas.
Our Hydraulic Drive Unit is powered by a diesel engine which may be placed outside to eliminate smoke, fumes and noise from the work environment.
The Rotor is then spun up to between 150 and 200 rpm. Three runs are required to perform a balance calibration and then the final correction is made and verified.

This Rotor was balanced to: 060mils @ 103° left and .026mils @ 315°
The residual imbalance was 35 oz/in in the left plane and 18 oz/in in the right plane.
The required correction weight would have been 1.447oz in the left plane
and .745oz in the right plane, on a 91,000lb rotor.
The entire Balance Unit will fit on our semi-trailer and is easily transportable anywhere within the United States and Canada.
Maintenance benefits of having your rotating equipment dynamically balanced.
Often there are issues with vibration, stress, or life expectancy of machinery that relate directly to the balancing of rotating equipment. Prime Field Service has the capability to detect, monitor, and correct these issues, both in-house and on-site.
Balance is an especially sensitive issue in high-speed or precision equipment. It affects production rate and quality of product, as well as the lifespan of the equipment. It has been documented by many large processing and production industries, that the money saved by longer equipment life and lowered maintenance costs, can drastically increase profits, product quality and customer satisfaction. Prime Field Service also has a full condition monitoring program, that can be custom tailored to your facility. See our Predictive Maintenance Page.
Our custom built Balance Stand is designed so that it can be mounted to standard gauge railroad tracks. This gives our stand a very solid, ridged and safe foundation for the balancing of very large rotors, up to 300,000 pounds and almost twenty (20) feet in diameter.
