Jun 15, 2008

Wanpela blok ain, tripela 'precision system' i stap insait long en: 'flatness' long 'mounting face', 'cylindricity' na 'coaxiality' long 'bore', 'roughness' long 'sealing face'. Masin bilong ol i save pait wantaim em yet, na dispela i as na ol kwotesen bilong wankain droing i save kisim mak bilong faivpela.

Bilong wanem ol bodi bilong valv i strong: Tripela 'Precision Systems' insait long wanpela hap

Bodi bilong haidrolik valv i luk olsem wanpela blok we i gat ol hul insait long en. Long praktis tripela 'precision system' i stap insait long wanpela hap: 'flatness' long 'mounting face', 'cylindricity' na 'coaxiality' long 'spool bore', 'roughness' long 'sealing faces'. Masin oda bilong ol i pait long em yet. Bore pastaim na bihain mill, na strong bilong pasim i paulim raunpela bilong bore; 'mill' pastaim na bihain 'bore', na namba tu 'clamping' i mekim pes i tanim.

Long dispela as ol kwotesen bilong wankain droing i save stat long planti ten i go inap long planti handet yunit bilong mani. Difrens i no long stretpela bilong masin tasol sapos ol i bin tingim gut rot bilong proses: hamas operesen i fit insait long wanpela 'clamping', hau ol i senisim 'datum', we 'heat treatment' i stap long en. Wanpela stua we i no bin tingting gut long en i save givim liklik prais, i save lusim mani long ol pipia samting, na i save givim bek dispela lus olsem dilei o prais i go antap.

Pasin bilong pasim pes: Rafpela em i mak bilong en, weivnes em i hevi bilong en

Ol pes bilong pasim i no save bagarap bikos ol i no gutpela inap; ol i feil bikos ol i no flat inap. Wanpela Ra 0.4 pes wantaim 'waviness' i save givim wanpela 'leak path' long O-ring, na wanpela Ra 1.6 pes wantaim gutpela 'waviness control' i save pasim gut long liklik presa. Olsem na ol mak bilong kisim i nidim Ra na 'waviness', o 'flatness', wantaim. Ra tasol i no inap.

Long sait bilong masin, bekim em long bosim kaikai bilong tit na tul long taim bilong pinisim miling bai ol i no ken kamapim ol 'regular waviness', na long putim 'lapping' o 'honing' long hap we i gat nid. Long ol 'die casting blanks', yu mas tok klia olsem 'machining allowance' em i namba wan: 'uneven' alawens i save mekim 'cutting force' i senis senis, na dispela senis i kamap stret olsem 'waviness'.

Kros Holes: Rausim ol 'burring' em i ples we ol i save makim 'yield'

Ol bodi bilong ol valv i gat ol hul we i bruk, na taim ol i drilim ol i save lusim wanpela 'rolled burr' long wanwan hul. Burr i no inap long kamap ples klia, i save lus bihain long ol i bungim, na i save stap namel long 'spool' na 'sleeve', na dispela i save mekim 'sticking' o 'internal leakage' i kamap. Wanpela bikpela hap bilong ol nupela valv we i no inap long wok long 'test bench' i go bek long ol 'cross-hole burrs'.

Wok bilong rausim ol 'burring' i dipen long 'hole diameter' na 'intersection angle': 'mechanical deburring' wantaim wanpela tul, 'abrasive flow' bilong ol liklik hul na ol kompleks 'intersection', o 'electrochemical deburring' bilong kisim gutpela volium. Olgeta tripela i wok, wantaim narapela narapela kos na wankain pasin. Taim yu laik kisim wanpela saplaia em i gutpela long askim stret long hau ol i save rausim ol 'cross hole' na hau ol i save sekim risal bilong en. Wanpela saplaia husat i no inap long tok klia long verifikesen ating em i no bin bosim.

Presa Testing: Rot i bikpela samting moa long presa

Ol 'valve bodies' i save stap olsem 'proof' na 'leak test' pastaim long ol i salim i go, tasol wanem presa, hamas taim na skelim olsem wanem planti taim ol i no klia tumas. Komon asua em long tokaut long presa bilong tes na i no gat taim bilong holim o mak bilong kisim, olsem na saplaia i save testim inap long tripela ten seken na kastoma i kisim moa long faivpela minit. Nogat wanpela man i rong na nogat wanpela samting i wankain.

Wanpela ful spesifikasen i tokaut long 'medium' (wara o ges), 'test pressure' (planti taim 1.5 taims mak), taim bilong holim i kam long volium na 'allowable decay rate', 'acceptance threshold', na ol step bilong 'drain' na 'rust-prevention' bihain. Ges tes i nidim tu sampela moa sefti provisen: kompresen ges i save bungim planti eneji, olsem na bruk em i moa denja long wanpela haidrolik tes.

Kasting o Masin: Bilong wanem wanpela as tasol i win

Ol 'valve blanks' i save kamap long 'die casting' o 'gravity casting', na ol i save wokim masin long ol narapela hap. Tupela saplaia i bruk, tok pait i ken kamap: man i wokim masin i tok alawens i winim mak, man bilong wokim masin i tok alawens i no wankain i lusim blakpela skin. Man i baim samting i kisim pe bilong en, long rot bilong kisim blakpela skin o rausim dispela hap graun.

Ol bodi bilong valv i gutpela long wanpela saplaia we i save mekim wok bilong kasting na masin, we alawens, datum, hat tritmen na deburring i stap insait long wanpela proses pepa na wanpela lain tasol i gat hevi. Em i tu as na, taim ol i skelim ol saplaia bilong ol masin, pasin bilong wokim ol tul bilong ol yet na wokim ol blank bilong ol yet i tok moa long namba bilong ol masin senta.

Klinpela pasin: Samting yu mas mekim we i no inap kamap long droing

Klinpela pasin em i wanpela samting we i no save kamap long droing tasol i save makim bikpela hap bilong pe bilong waranti. Sanbij we i stap insait long wanpela hul, ol liklik hap bilong 'cross-hole deburring', 'aluminium swarf' we ol i no bin pairapim aut pastaim long ol i bungim - olgeta dispela i save raun wantaim oil taim sistem i wok, na i save bagarapim 'spool' na 'port plate' bilong pam. Indastri i tokaut long mak olsem ISO 4406 patikel kaun o NAS 1638 klas, tasol planti baia i raitim tasol olsem insait i mas klin, we i no makim wanpela samting.

Wanpela 'executable specification' i brukim 'cleanness' i go long 4-pela samting: 'sampling method', maski em i 'flushing' o 'extraction'; instramen, wanpela 'particle counter'; klas bilong kisim, eksampel ISO 4406 18/16/13; na ol samting bilong lukautim pastaim long ol i putim long paket, mining olsem ol 'plug', 'desiccant' na wanpela 'double bag'. Taim ol i raitim olgeta foapela, wanpela saplaia i ken sekim em yet na kisim i gat as bilong en.

Long sait bilong masin i gat tripela step we i wankain: 'high-pressure flushing' bihain long 'deburring', 'ultrasonic cleaning' pastaim long bungim, na 'borescope sampling' pastaim long laspela inspeksen. Borescope step em i wanpela we ol i save lusim planti taim, na em i wanpela rot tasol long lukim ol samting i stap yet long as bilong wanpela kros hul. Sapos yu askim long lukim ol rekot bilong 'borescope' long taim bilong odit, dispela i gutpela moa long ritim 10-pela pes bilong ol pepa bilong sistem.

Hau long askim long wanpela 'Valve Body Quote'

Ol i daunim i go long 6-pela lain askim: blank sos na alawens standet; proses routing na datum; Ra na 'waviness' mak long ol 'sealing faces'; 'cross-hole deburring' rot na verifikasen; ful presa-tes paramita; na kapasiti na 'rhythm' long taim bilong 'ramp-up'. Askim ol dispela 6-pela na 'spread' namel long ol 'quotes' bai kamap klia na i no wanpela 'guess'.

Wanpela tok lukaut: wanpela valv bodi em i wanpela singel-poin-feil pat, na wanpela stop lain i gat bikpela pe moa long dispela hap. Antap long namba wan saplaia em i gutpela long kamapim wanpela bek-ap saplaia wantaim wanpela multi-sos saplaia arenjmen wantaim tok orait fail bilong em yet, na i no olsem wanpela nem long wanpela lista bilong ol samting we inap kamap, we tupela i wok long wankain droing rivisen na akseptens standet. Long ol 'hydraulics', 'emergency backup capacity' em i no narapela rot bilong painim ol samting; em i insurens long prodaksen kontinuiti. Lukim ol ditel bilong prodak bilong kampani
