Starting Procedure of a Diesel Generator

Normal Starting Procedure of a Generator

Do not depress the accelerator pedal or move the accelerator lever from the idle position while cranking the engine. This can result in engine over speed and severs damage to the engine.]

To prevent damage to the starting motor do not engage the starting motor for more than thirty seconds, wait two minutes between each attempt to start the starting motor.

Engine equipped with air starting motors require a minimum 70 psi which is recommended by manufacturer.

a.       Disengage the driven unit or if equipped put the transmission in neutral.
b.      With the accelerator pedal or lever in the idle position turn the key switch to the ON position and wait for the wait to start lamp to go out then turn the key to the start position.
c.       If the engine does not start after three attempts check the fuel supply system. Absence of blue or white exhaust smoke during cranking indicates no fuel is being delivered.

The engine must have adequate oil pressure within fifteen seconds after starting. If the warning lamp indicating low oil pressure has not gone out or there is no oil pressure indicated on a gauge within fifteen seconds, shut off the engine immediately to avoid engine damage.

Engine should be idle 3 to 5 minutes before operating with load.

After starting a cold engine, increase the engine speed slowly to provide adequate lubrication to the bearings and to allow the oil pressure to stabilize.

      One should not operate the engine at low idle for long periods with the engine coolant temperature below the

-          Fuel dilution of the lubricating oil
-          Carbon build up in the cylinder
-          Cylinder head valve sticking
-          Reduced Performance

“Equalizer connection is needed in lap winding armature but not in wave winding “ why ?

The equivalent circuit of a four point – pole dynamo with a simplex winding. The voltage induced in each path is assumed to both to be same and should be if the reluctance of each magnetic path is the same, so that the lines of flux cut by each inductor of each path are the same. However wear of the bearings or deflection of the armature shaft may cause the armature to be closer to some poles and farther from others, thus changing the length of the air gap, and therefore the reluctance of the magnetic circuits of the poles is not identical. This factors cause the voltage in the materials making up the magnetic circuit. These factors cause the voltage in each parallel path differ, and the unequal voltages in turn cause flow of a circulatingcurrent through the windings and brushes , undue heating of the armature and waste the power. To reduce the circulating current, points on the winding which should be at the same potentials are brought to the same potentials by connecting them with …



Differentiate among progressive die, compound die and combination die.

Progressive die: The dies which performed two or more operations at different stages every time the ram descends is known as Progressive die.
The principle advantage of Progressive die is in the number of operations that can be achieved with one handling of the stock strip. The main disadvantage is that work pieces may become “dished” as they pushed through the die as they generally have very little support.

Compound die: A compound die differs from a progressive die in that it performs two or more cutting operations during one stroke of the press at one station only.

Compound dies are slower in operation than progressive dies but they have advantages for certain jobs, especially where tolerance are close (1)the cutting operation, by the action of the knockout plate ,ensures flatness of the blank.2 Large parts can be blanked in a smaller press if compound dies rather than progressive dies areused.
Combination dies:A die in which a cutting operation is combined with a noncutting operation …

Why a dc generator fails to build up voltage?



Boiler: A steam boiler is usually a closed vessel made of steel. Its function is to transfer the heat produced by the combustion of fuel to water and ultimately to generate steam.
Types of boiler:
           1. Fire tube or smoke tube boiler            2. Water tube boiler

                                          Figure: Boiler
Fire tube boiler: In fire tube steam boilers, the flames and hot gases, produced by the combustion of fuel pass through the tubes which are surrounded by water. Fire tube boilers are generally used for relatively small steam capacities and low to medium steam pressure. As a guideline fire tube boilers are completive for steam rates up to 12000kg/h and pressures up to 18 kg/cm².Fire tube boilers are available for operation with oil, gas or solid fuel.

                                   Figure: Vrious parts of boiler
Example: Cochran boiler, Locomotive boiler, Scotch marine boiler, Velcon boiler, simple vertical boiler.
