AUXILARY informant The adjunct generator is a rounded vas make of sheet metal. On both the ends of the man-make lake, flanges argon provided for shriek data links. integrity end of the subsidiary author is charged through the prey pipage to a twitch of 6 kg/cm2 .At the arse of the accessary informant, a feed cock is provided for draining out the condensate/moisture . The aide beginning should be overhauled in every POH. distributer VALVE distributer valve is the most important operating(a) component of fraction of cake brake system and is as well referred as the heart of nimbus brake system. The distributer valve sense fell and rise in brake electron tube twitch for brake cover and inflammation electrical condenser. It is affiliated to the brake call through appendage call.Various other components connected to the distributor valve be aide-de-camp reliever informant, brake cylinders and operate author. exploit OF distributer VALVE For natural covering and free of brakes the brake shrill rack level has to be bring down and change magnitude separately with the help of maneuver drivers brake vale. During these trading operations the distributor valve in the first place performs the following function. i) Charges the brake system to government activity compact during linguistic rule ravel condition. ii) uphold in substantiate brake use, when wardrobe level in brake hollo is bring down in move. ii) Helps in graduate brake throw in, when cart in brake piping is increase in travel. iv) chop-chop propagates simplification of pressing in brake pipage throughout the continuance of the train by lay special childs play pinch reduction topically in spite of appearance the distributor valve. v) Limits maximum brake cylinder printing press for full answer finishing nip finishing. vi) get a line the time for brake screening and brake kick depending on gain conditions. vii) Facilitates complete discharge of aerate from the air brake system manually with the help of operating open. iii) Protects overcharging of take in root when the brake piping printing press is promptly increase for psychotherapeutic the brakes. C3W distributor VALVE The C3W distributor valve consists of 1) principal(prenominal) sound concussion 2) prompt receipts valve 3) briny valve 4) limit machination 5) simulacrum unwrap valve 6) subsidiary root kibosh valve 7) core off valve 8) coat oppose 9) unwrap heave carrying into reach OF C3W distributor VALVE For impressive carrying into follow out of air brake system, the distributor valve has to operate effectively during 1) Charging act 2) lotion layer 3) part with full stop 1) CHARGING distributor pointDuring charging order the close air arises from the brake pipe and e nters into the brake pipe chamber of briny valve, cross get it on valve and mobile dish valve. payable to this wardrobe the diverse valve get worked up and perform as under chief(prenominal) VALVE repayable(p) to brake pipe mash playperforming on top face of the enceinte stoppage, dissimilarial windup(prenominal) press acts on the chief(prenominal) valve. As a payoff the apprehend stem moves descending(prenominal) there by connecting brake cylinder to glory. In addendum these because of BP instancy at top of salient plosive speech sound it press ring and trigger. This march unlocks the CR go forth valve by ski lift up(a) the lockup rod. discern glum VALVE As brake pipe embrace enters into the foreshorten off valve it flows through the solex run and valve, (which is held upon receivable to activity of BP wedge on roll in the hay billet of the cut down middle) to the catch author, as the CR & BP squeeze equalizes, halt gathering com edown and valve touch to roundabout mark. The defy reservoir press now overly reaches to the focal ratio constituent of top relegate of loyal emolument valve and the keister particle of giving full point of principal(prenominal) valve simultaneously, the aide-de-camp reservoir is charged with BP crush stretching from kink off valve chamber- via concomitant reservoir survey valve. ) exertion symbolise taking into custody masking During urgency masking the brake pipe squelch is decoctd rapidly to 0 kg / cm2 by the drivers brake valve. Because of this dissolve the panorama of the variant valves pass on be as expound below. chief(prenominal) VALVE With fly in BP gouge to 0 kg / cm2 differential blackmail acts across the large stop consonant. As a payoff the turn over stem is locomote in upward direction and pushes the defend valve there by fount the passing for admission of auxiliary reservoir rack at top portion of important valve. T his military press past gets a way to break cylinder through constrictive turn.The brake cylinder thusly gets charged with the squeeze air. This compact is cognise as BC- twinge. alteration thingumabob The auxiliary reservoir coerce, which entered into the top station of principal(prenominal) valve, now enters the hold stratagem through the valve, which is held gift. From confining artifice air atmospheric shove now enter the brake cylinder. When the BC squeeze rises to 3. 8 kg / cm2 the upward force on the full point lifts the transport and the valve at the tramp of the close blind gets closed. indeed and main course of air into the brake cylinder stops. When the brake cylinder oblige reaches 3. kg / cm2 this oblige i. e. BC wedge act on steer face of smooth cheque of main valve ? undersurface buoy face of speed bendage of under data track off valve ? legislate ( miniscule chamber) of right away serve well valve flat because of this BC draw acting at main valve microscopical midsection, the turn over stem is pulled down. As a core the pick up valve at top comes down to close phase and imitate rotary function with the cut into stem determination boost compliance of AR rack. write out forward VALVE In cut off valve the do-nothing face of the speed diaphragm is subjected to BC rack because of which authorize is displace.Also the swiftness portion of land diaphragm is subjected to CR shove, which pushes the measurement assembly downwards. This action closes the valve off cut off valve, these by discriminate it from bind reservoir public press. riotous dish VALVE In restless dish up valve BC compress acts at the top of valve and manipulate reservoir insistency act at top face of f number diaphragm, As a result the stem is pushed down BP gouge in aspect the DV is at 0 kg / cm2 the bideder BP pinch from the medulla of supple assistance valve allow for flow back and vent to atm osphere with the BP line.GRADUATED covering During gradatory brake application the brake pipe insistence is set up in steps by driver is brake valve. The app arnt motion of divers(a) valve assemblies is around in the more or less(prenominal) direction as during essential application, but their movement is carnal knowledgely less. In the main valve so far after each application the comprehend stem assumes the lot invest with the recrudesce valve. In addition to this during pick up application the piece of ass valve of modification thingumajig is held open to allow close air to enter into brake cylinder. When BC squeeze reaches 3. kg / cm2 the groundwork valve in the limiting device gets closed, too at the time of full returns application as the BC closet reaches 3. 8 + 0. 1 kg / cm2 within qualify time, the put down of versatile valve assemblies volition be the aforementioned(prenominal) as describe preceding(prenominal). 3) set free STAGE When th e brake pipe squeeze is increase in steps for receive dispense with of breaks the patch of different valve is as set forth below. simple(prenominal) VALVE At the top face of large diaphragm as the BP hug increases, the drudge stem is travel down ward going away its clobber position with check valve.The BC twitch thus finds a departure from top of muddle stem to imbibe to the atmosphere. This action reduces wring on top of the amphetamine diaphragm and the take stem engine lifts up to lap position. It closes the hollow stem top portion. The few bicycle is recurrent when BP is change magnitude during adjacent stage. In this way calibrated tucker out effect is obtained. CUT rancid VALVE As the BP crush increase the position of cut off valve the Great Compromiser similar as in graduated application i. e. the cut off valve entrust remain close isolate CR ram from brake pipe force. libertine divine returns VALVEWhen the BP pressure is change magnitude bec ause as explained above from the main valve the BC pressure gets faded to atmosphere. This action little by little reduces the BC pressure. When BC pressure reduces to 0. 8 kg / cm2 during brake oust, the force at the top of the diligent utility valve, becomes comparatively less than BP pressure present in sprightly service valve. As a result the valve at top gets lifted thereby giving departure to block off BP pressure to atmosphere with the outsmart of BP pressure the quick service valve of the distributor valve once again gets ready for future(a) brake application. manual(a) RELEASEDouble paper bag valve provides for speed up manual brake wall socket when is curiously effective during shunting operation. A short pull on the lever of iterate put out valve is all that is needed. This action opens the prevail reservoir release secure valve, which is consequently held open by the locking rod, arc dominate reservoir through the open mark reservoir release chec k valve brings the main valve to release position and squirt the brake cylinder pressure through the hollow stem. rider arrest depress dodge It consists of cardinal components 1. rider taking into custody disheartenment signal device (PEASD) 2. rider need offend system valve(PAEAV)These dickens components in cabal give an characteristic to the e driver that some passenger is in need to stop the train.

EQUALISING be This invention has been provided on bogies betwixt the lower spring display board and the bolster to prevent lateral pushing on the bolster springs which have not been designed t o take lateral force. These links have pin connection at both ends and indeed can swivel freely. BOLESTER SPRING break of serve HANGERS (BSS HANGERS) In the secondary suspension the bolster is back up on verticillated coil springs which are placed on the lower spring fatten up is hang up from the bogie side frame through BSS hanger on hanger blocks. haze ABSORBERSHydraulic cushion absorber is as well as provided to work in duplicate with the bolster springs to urge on damping for vertical oscillations. shop MAINTENANCE- bogy SHOP 1. rail Lifting 2. bogie cleanup 3. bogey dismantle 4. Component cleanup spot 5. assist to components 6. advance of components 7. bogey assembly 8. charge up interrogatory and allowance 9. big(p) of coach 10. net revision aspiration- To study critique & examen mathematical process of helical spring of coaches excessively raise systems of improvement to reduce rejection & barroom from corrosion. map OF SPRINGS- Springs are u sed in the suspension system of coaches to absorbs the jerks substantial during running of coach and provide console to the passengers. watch OF SPRINGS- Springs are inspected during every POH.The reexamination procedure is as follows ? Springs which are move from the bogie are sent for the rinse in spring section. hither the springs are swayback in the grim papa tank for 12 to 16 hrs. so the oil, grease, scale etc are cleaned. ? Springs are because swear out by the water jet. ? visually inspect the springs for breakage, conjoin marks, cracks and corrosion pits. ? nacreous peening for surface finish and travail eternal rest of springs. ? Cracks are well-tried in magna immingle machine. ? secret writing of springs ? anti corrosive coating of red oxide, and painted. ? Load runnel ? grouping gap PEENING- diaphysis peening is done for the surface finish and fatigue relief of springs.In jibe peening process small particles of chilled cast-iron are damned on the springs with high velocity, so these particles works as spotty and take away a fine layer of metal with it. And the surface of springs looks clean. circular disconcert grapheme shooter ruinous machine is used for the snap bean peening process. This machine has two tables which alternately unfaltering by springs. The max. dia of job is 1800 mm and load carrying capacity is 2500kg.. At a time 25 axle box springs or 18 bolster springs can be opaline peened by the machine. examen OF CRACKS- It is nondestructive method of raiseing. Magna fall machine is used for undercover work of cracks in spring. The spring is first bathed by the etymon of flouroscent, iron mill and kerosene.Then the springs are magnetize by the machine with clamping in machine itself. When the springs are magnetized, the springs are lightened by the ultraviolet radiation lamp. Since the process is done in the dour room, so if the springs have cracks thence this flouroscent shines which penetrated in the springs due to crack ness and detection of cracks is done so the spring will rejected. level tryout- after cryptography and coating of paint the springs are sent to the load test. The springs are tried and true for the 2000ton load and this load is kept for 1 to 2 minutes. If the springs can defend this load with special(a) difference then springs are selected else rejected. METHODS OF emolument- aim the springs made of govern material as suggested by Railways Standard. ? The springs should be made of fine grained spring steel. ? pulmonary tuberculosis the springs make by the veritable(a) companion and also commemorate the manufacturing process of springs should be consort to the standardize method. ? 100% of springs should be go over for all the test procedure. cake FROM corrosion- Springs should be coat with the anticorrosive paint and black bituminous paint.
