Balancing Jet Fuel-Powered Turbine Engines

picture of a marine turbineLarge stationary jet fuel-powered turbines are the solution for many industrial applications where large amounts of rotational energy is needed in a comparatively small and compact package. As evident in commercial airline applications, the design constraints and the engineering solutions provided by jet turbine power, allow these motors to be used in a variety of relatively portable applications.

At HI-TEK Balancing, Inc, we have set the industry standard for solving vibration problems that arise in turbine engines and are implemented in new portable applications during the design and installation stages. These applications where large power density is required include cruise ships, large oil tankers, large cargo ships, and military vessels. Turbine engines must be mated to either a generator or directly to a propeller via a transmission. The shafts that are used to connect these devices are often unique to the application of the turbine. Turbines are balanced by the manufacturer, but the unique connecting shafts require balancing due to error generated by the realities of the shaft manufacturing tolerances and reassembly fit-up error.

With the assumption that the majority of vibration is caused by unbalance of the shaft, the shaft vibration is measured by reading the orbital acceleration data at the ends of the shafts. Technically speaking, four accelerometers are attached to the turbine engine, two horizontal, two vertical. Four additional accelerometers in the same orientation are attached to the receiving end, gearbox or generator, depending on the driving method of the particular ship.

Vibration is usually caused by parts that are unbalanced as a result of asymmetrical manufacturing.  To really understand vibration and its sources, you need to have a thorough knowledge of manufacturing processes. Resolving a vibration problem requires going beyond just balancing components to address the manufacturing cause.

We know the questions to ask to get you the solutions you need.
What sets us apart from the competition is our in-depth manufacturing expertise. Our firsthand experience in machining, molding, and finishing enable us to know where problems occur, quickly identify your vibration source, and provide the best, most economical remedy to eliminate it. Our vibration analyses and solutions are precise, practical, and presented in a clear, easy-to-understand way that enables you to implement them in hours or days, not weeks or months.

Complete vibration analysis and balancing services, from prototype to production
Around the corner or around the world, we can accurately diagnose and solve your rotating or oscillating equipment vibration challenges quickly and cost-efficiently, in our facility or yours. Our in-house capabilities range from diagnosing and fixing components weighing under an ounce, all the way up to ten tons. From wire winders in China to prototype micro-medical breathing assist blowers, we can analyze and solve virtually any vibration problem, from the largest industrial applications to the smallest technological ones.

Air Handler Shaft and Bearing Repair and Noise Reduction

“We replaced the bearings three times and it still makes noise”…Sound Familiar?

If you are responsible for the reliability of HVAC air handling equipment, you probably have units that rumble and make more noise than they should.

Most often this is due to the shaft to bearing fit up. Improper bearing installation can cause the bearing’s inner ring to wear a groove into the shaft.

Once the shaft is grooved it’s only a matter of time before you realize that repeated bearing changes is not the solution. You also know that shaft replacement is difficult and very expensive.

HI-TEK specializes in shaft repair of all rotating machinery. Continue reading “Air Handler Shaft and Bearing Repair and Noise Reduction”
