US8092150B2 - Gas turbine with axial thrust balance

A method for axial thrust control of a gas turbine, and a gas turbine with a device for controlling axial thrust are provided. A gas turbine, with regard to aerodynamic forces and pressure forces, which exert an axial force upon the rotor, is configured such that at no-load and low partial load it has a negative thrust, and at high load it has a positive thrust.

Thrust bearing protection. - P&W FT8 / Solar Turbines

Sep 18, 2021· On a turbine the active thrust bearing is the only one which takes the wear so this is the one which has to have accurate protection. So we set the channel zero position voltage to the voltage we note on the channel when we start the unit up after we install it. In this case we would insert the nuer -11.6 volts, and because we configure the

UPTHRUST PROBLEMS ON MULTISTAGE VERTICAL …

Figure 1. Typical Multistage Vertical Turbine Pump. Calculating Net Thrust Forces In vertical turbine pumps, the axial thrust forces are similar to those for centrifugal pumps, except that additional forces must also be considered. Under normal conditions, vertical turbine pumps have thrust loads acting parallel to the pump shaft that include:

Miba: Tilting Pad Thrust Bearing

Tilting pad thrust bearings are designed for the most demanding turbomachinery appliions. Due to the tilting capability of the individual pads, thrust bearings allow high sliding speeds ( e.g. 160 m/s and above). With appropriate oil supply, bearing loads of >4 MPa are achievable for continuous operation.

Steam Turbine Basics

Reaction turbines utilize either a parallel plate or a Kingsbury type thrust bearing. On a parallel plate thrust bearing pressure is applied to the plates but because they are solid shoes, the pressure may only touch a portion of the shoes resulting in uneven wear. The shoes of the Kingsbury thrust bearing are made of

Gas and Steam Turbine Bearings for Thrust and Journal Use

In the early 1980s, gas turbine bearing and steam turbine appliions began pushing the safe operating limits of flooded tilting pad hydrodynamic bearings. Shaft speeds and loads had increased to the point that bearing surface temperatures and associated power losses were of concern in the design of larger, faster, more efficient turbines.

Steam Turbine Tilt Pad Thrust | MD&A Turbines

Tilt Pad Thrust. Troubleshooting the source of differential thrust bearing temperatures can be frustrating and costly, especially if load reduction action is required. A tilt pad thrust bearing retrofit can be a cost-effective solution when sole plate settling or other foundation changes have created an undesirable alignment condition.

Meeting Energy Demands | Lubricants for Turbines | Shell

Using an inferior oil can lead to turbine problems due to poor ther¬mal stability and oxidation, this degrades the oil and will adversely affect the performance of the turbine. In time this can cause var¬nishing on the thrust and journal bearings, which can disrupt heat transfer and lead to higher bearing temperatures.
