                       Mercerising Machine


Mercerising: Mercerising is the process by which the fabric is treated with NaOH solution to cause swelling of fibers. This results in improved lestre, strength and dye affinity. Cotton is mercerized under tension and all alkali must be washed out before the tension is released or shrinkage will take place .Mercerizing can take place directly on grey cloth or after bleaching .

       Section of mercerizing machine:

             1. Coustic Zone
             2. Stabilizings Zone
             3. Washing Zone
             4. Drying Zone

                                                    Washing Machine


Washing: Washing is the process to remove the impurities from the cloth. Water and soap are used as washing substance and also pH control.
              Main chamber of machine:

                    1. Cold wash chamber
                    2. Hot wash chamber

                                                Cold wash chamber


Cold wash chamber: In this chamber the cloth is washed by cold water. It is placed on the two ends of the machine.

                                                  Pad steam machine


Pad steam machine: Pad steam machine is one kind of washing machine. The basic difference from washing machine that pad steam machine contains a steamer. In pad steam the cloth pass through the steamer where the cloth is washed by steam at temperature 95-98°C and color fixation these zone. There are 20 rollers which are called dryer. The dryers are rotate by supplying power from motor by chain, gear and belt. The dryers dry the cloth by supplying steam from steam boiler. The clothes are collected by the quick return mechanism.

              Application:

               1. To mix the color fixation of the cloth
               2. To wash the cloth
               3. pH control




                                        Cold Pad Batch (C.P.B)


C.P.B:
C.P.B or Cold Pad Batch machine is one kind of one color dyeing machine. In C.P.B machine there are spinner roller, steel roller and rubber roller. The spinner roller reduces the folding of cloth and the friction of rubber roller to help the cloth to spin the roller. In C.P.B machine the cloth pass through the roller and below the roller there is a container. The mixture of deices and chemical (NaOH/Urea) by the ratio of 4:1 used to dyeing the cloth. The chemical and deices kept in separated tank and by the help of dozzins pump chemical and deices mixed I 4:1 in a container. From this container using dozzins pump the mixture sprayed on the cloth. By the help of rubber roller the mixture of chemical and deices mixed uniformly on cloth. Finally the cloth is dried by the roller dryer.

                                                    Jigger Machine


Jigger machine: Jigger is a multipurpose machine used for dyeing, scouring, bleaching etc. This machine is used for small purpose generally used for processing sample/short quality dyeing.

                                   

                                    Figure:  Jigger Machine

                   Main parts of machine:

                       1. Hydraulic motor
                       2. Heat exchanger
                       3. Coil
                       4. Electric motor / Pump

“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 …

Boiler

Boiler


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.

Why a dc generator fails to build up voltage?

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 …
