Experimental Modeling of a Long Orifice-type Restrictor of High Speed Turbine Hybrid Bearing
نویسندگان
چکیده مقاله:
To overcome the space limit of orifice-type and capillary restrictors in hybrid bearings, a kind of atypical long orifice-type restrictor is proposed and its experimental model is established. Through the analysis of the structure and flow rate of orifice-type restrictor and capillary restrictor, a long orifice-type restrictor and a feasible experimental modeling method are presented by use of orifice plate instead of the whole bearing. The flow rate of water film restrictors are tested under the aspect ratio of 4-10 and the pressure difference of 1.5-5.5MPa and the experimental model of long orifice-type restrictor is established. The result shows that the restrictor of atypical structures needs to be modeled by experiment. The flow discipline of atypical restrictor is approximate to typical orifice-type restrictor and the throttling model is a nearly turbulent model.

Experimental Study of a High Speed Micro Waterwheel
Waterwheels are the oldest types of hydraulic machines. These turbines are of relatively simple design, large diameter, low rotational speed and high torques. But applying them as micro hydros of high speed and small diameter is yet to be explored. A micro hydro waterwheel of one meter diameter was designed and manufactured at the Iranian esearc†h Organization for Science and Technology (IROST...
متن کاملDirect load measurement of a Wind Turbine High Speed Shaft Bearing in the Field
Small piezoelectric transducers bonded to the outer raceway of a rolling element bearing can be used to send ultrasonic pulses to the element-raceway contact and receive reflections. Interpretation of the magnitude and time of flight (ToF) of the reflections can be used to deduce amount of load imparted between roller and raceway. The approach is most successful when the sensor is smaller than ...
متن کاملANFIS modeling and validation of a variable speed wind turbine based on actual data
In this research paper, ANFIS modeling and validation of Vestas 660 kW wind turbine based on actual data obtained from Eoun-Ebn-Ali wind farm in Tabriz, Iran, and FAST is performed. The turbine modeling is performed by deriving the non-linear dynamic equations of different subsystems. Then, the model parameters are identified to match the actual response. ANFIS is an artificial intelligent tech...
متن کاملPhysical Modeling of a Hybrid Wind Turbine-solar Panel System Using Simscape Language (RESEARCH NOTE)
Being sustainable and producing little waste products, the renewable energy knows a rapid deployment. Unfortunately, the intermittent characteristic of these energies makes them difficult to control. The influence of this aleatory character can be reduced with the coupling of two or more sources of renewable energy and secondly with a sound management of storage systems. This new configuration ...
متن کاملDevelopment of Orifice-type Aerostatic Thrust Bearing for Precision Machine
Air bearings are used in precision machines and measurement equipments for recently years. Unlike conventional ball or roll bearings, there is no physical contact between the sliding surfaces and the moving surface. Therefore, the structure with air bearings can glide smoothly on the other surface to avoid generating the small particles from the friction contact and also minimize the control ef...
