This is bec ause of two reasons. BHEL has joined the “Global C ompact” of United Nations and has committed to support it and the set of core va lues enshrined in its nine principles: The power plant equipme nt manufactured by BHEL is based on contemporary technology comparable to the be st in the world and is also internationally competitive.

This type of damping is because of the inherent damping properties of the ma terial which makes up the component. Each retaining rings with its shrink fitted.

As the blades pass the nozzles of the stage, they encounter fl ow disturbances due to the pressure variations across the guide blade passage. Steam generator up to MW unit size. To carry efficiently electric, magnetic flux. We have for RC bock and diode circuit. The pressing of overhang portion is carried out on special ring type hydraulic press, whereas slot portion is pressed manually with the help of slot wedges. Out of these damping mechanisms, the material and aer odynamic types of damping are very small in magnitude.

In ca se the frequencies of the blades tend towards resonance due to manufacturing ina ccuracies, tuning is to be done on the blades to correct the frequency. This can be done by a manual process or by us ing a machine called machine tool traditional machines namely lathe, milling ma chine, drilling, shaper, planner, slotter.

Another blade mat erial is titanium.

This construction requi res a disc rotor. The shaft is rigidly coupled to generator rotor and exciter rotors are than supported on these bearings. It is used because of its high yield strength, endurance limit, duc tility, toughness, erosion and corrosion resistance, and damping.

hafidwar This type of insulation is more reliable for high voltage. During this phase, the damping is very 32 less. The fact that the pressure does not drop across the moving blades is the d istinguishing feature of the impulse turbine. Blades of all the stages of turbine are made in this shop only.

The enthalpy o f the steam decreases. These secondary proce sses are mainly required for achieving dimensional accuracy and a very high degr ee of surface finish. I am highly indebte d to, MR.

This tun ing is done by grinding off material at the tip which reduces the inertia more than the stiffness to increase the frequency, and by grinding off material at t he base of the profile which reporr the stiffness more than the inertia to re duce the natural frequency.

Steam turbines and generators up to MW capacity for utility and combined cycle applications Capability to buel up to MW unit cy cle. We think you have liked this presentation. Test procedure for high voltage on rotor winding of T G.

This has led to introduction of optimized design an d manufacturing of new products. These damping ele ments may be integral with blades, or they may be separate elements mounted betw een the blades.

Steel spacers are spot welded on stamping.

This procedure is for high voltage test on stator winding of turbo generator. Even where turbines are used to cool fluids, the turbines st ill produce power and must be connected to a power absorbing device that is part of an overall system. Bearing have provision for vibration pickup to monitor shaft vibration. TABLE 3 15 1. Test procedure for measurement of leakage reactance of TG stator winding — SCOPE — This procedure covers the leakage reactance measurement of stator winding after completion of winding.

To prevent the potential difference and possible corona discharges between the insulation and the slot wall, the section of bars are provided with outer corona protection. Center lathe machine up to maximum length of 16 m and diameter haidwar 3.

Rudr apur Component Fabrication Plant Italy Super rapid gun mount. When rotor is rotating at high speed, the centrifugal forces tries to lift the winding out of slots, they are contained by wedges. Pitch of a blade is the circumferential d istance between any point on the profile and an identical point on the next blad e. BHEL as a nhel of Pt.
