Each slots accommodated two bars. Though the theoretical impulse blades bolck zero pressure drop in the moving blades, practically, for the flow to take place across the moving blades, there must be a small pressure drop across the moving blades also.

Worki ng under the department I came to know about the basic grinding, scaling and mac hining processes which was shown on heavy to medium machines. The effect of this change in direction of the steam flow wi ll be to produce an impulse force, on the blade causing it to move. Up to 55 Tons per Piece Wt.

For this purpose DM water of proper specifying resistance is selected. 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. The example of parts produced by machining processes includes hand t ools machine tools instruments, automobile parts, nuts, bolts and gears etc.

In the case of a steam turbine, the pressure and flow of newly condensed steam rapidly turns the rotor. R is subdividing the frame and axial members to form ducts from which the cooling given to end from radial duct in the core and is recirculated.

This is due to the rubbing friction between the component under considerat ion with any other object. Log In Sign Up. The roots of the LP blades of preceding stages ar e of T-roots. In addition to demonstrated capability to undertake turnkey p rojects on its own, BHEL possesses the requisite flexibility to interface and co mplement with international companies for large projects rraining supplying complement ary equipment and meeting repory production needs for intermediate as well as fin ished products.

This condition gives zero friction damping, and only the material and aerodyn amic damping repoft. Seamless Steel Tubes xi. The high mechanical stress resulting from the centrifugal force and short circuit, torque called for a high specified mechanical and magnetic properties as well as homogenous forging.

It is therefore important to know the characteristics of the available engineering materials. It is forged from a vacuum cast steel slots for insulation of the field winding are made into the rotor body.

The main features of core are — i. The second part of the rotor is the drum end cover with shaft.

At the transition from the slot to the end winding portion of the stator winding portion of stator bars a semiconductor tape made up old polyester fluce is impregnated. In this section small jobs are manufactured like ringsstuds, disks etc.

Oil Field Equipment viii. The b olt holes in the flanges are drilled for smoothly fitting bolts, but dowel pins are often added to secure exact alignment of the flange joint. Also note that turbines in high haridwa applicatio ns are sometimes called expanders. Another blade mat erial is titanium.

Today BHEL has 14 Manufacturing Divisions, 4 Power Sector regional Centers, 8 Service Centers 18 regional offices and large number of Project Sites spread all over India and abroad enables the Company to promptly serve its customers and provide them with suitable products, systems and services efficiently and at competitive prices.

Christmas tree and Well head assembled. In case of hhel turbines, the inner casing parting plane strength becomes th e limitation, and therefore requires a large heat drop across the 1st stage. BHEL has supplied generating equipment to various utilities capable of generating hqridwar MW power. We have for RC bock and diode circuit. Center lathe machine up to maximum length of 16 m and diameter of 3.

The pressed core is held in pressed condition by means of two massive non-magnetic steel castings of press ring. The stator slots are provided with platinum resistance thermometer to record and watch the temperature of stator core and tooth region and between the coil sides of machine in operation. Their prime mover and current is supplied by exciter system. The elementary conductors to be Roebel transposed in the slot portion.

BHEL is one of the largest power plant equipment manufacturing firms in India and it ranks among the top ten manufacturers globally. Steam — turbinesHydro — turbinesGas — turbineTurbo generatorsControl panels, Light aircraftsElectrical machines.

Bhwl rotor slot milling machine up to maximum barrel length of mm, barrel diameter of mm and bblock weight of tones. However, for assembling and inspection purposes there is no other solut ion.

Water heat recovery boilers, gas turbines, heat exchangers and pressu re vessels, centrifugal compressors, electrical machines, pumps, valves, seamles s trainimg tubes, electrostatic precipitators, fabric filters, feport, fluidized bed combustion boilers, chemical recovery boilers and process controls. If this high steam is ap plied to a properly shaped turbine blade, it will change in direction due to the shape of the blade. Some processes produces finish products or articles into its usual form whereas others do not, and require further working to finish component to the desired shape and size.

Fabrication Large size fabricated assemblies or components III. Design of special ventilation is to ensure almost uniform temperature of rotor windings stator core. Hydrogen is contained within frame and circulated by fans mounted at either end of rotor. BHEL is geared up to turnkey execution of electric trolley bus system s, light rail systems etc.

For fascinating and monitoring the healthiness of bearing insulation, shaft insulation is provided Fig. The ring trainihg the flux by short-circuiting. Cg — capacitance with respect to ground called ground capacitance. Undertake initiatives to promote greater environmental responsibility and 9. This is bhek nozzle-passing frequency e xcitation.
