Ginawabalbulas et kaukolan ya ondalan ed nanduruman performance tests, say sankaimportantian ed saratan et say pressure testing. Say pressure test et pian nasubok no kasin say pressure value ya sarag na balbula et makatunongan ed saray kakaukolanen na saray totontonen ed produksyon.Diad TWS, sayanlemek ya akayurong a balbula na kulibangbang, kaukolan ya awiten so high pressure seat tightness test. Say pressure ya nibaga ed 1.5 times na PN et nepeg ya iyaplika ed danum ya nasubok.
Saray manunan salita:Pressure Testing;Anlemew ya akayurong ya balbula na kulibangbang; Pressure Seat Tightness Test
Kaslakan, say pressure test nabalbulanepeg ya unoren iray onggendan a prinsipyo tan panag-alwar:
(1) Diad inkalapagan, saybalbulaag-onsulong ed biskeg, balet saybalbulalaman tan bonnet kayari na pangapiger odino saybalbulasay laman tan bonnet ya walay aderal lapud corrosion et nepeg ya suboken no kasin mabiskeg. Parad safety valve, say pirmin presyon to, say presyon na pangiyurong lamet tan arum niran test et nepeg ya ontumbok ed saray detalye na saray instruksion tan saray matukoy a totontonen to.
(2) Say biskeg tan inka-malet na subok et nepeg ya gawaen antis nabalbulaaka-install. 20% ed saray low-pressure valves et spot-checked, tan 100% ed sikara so nepeg ya checken no ag ira kualipikado; 100% na saray medium tan high-pressure valves so nepeg ya nengnengen.
(3) Legan na test, say posisyon na pangipuesto nabalbulanepeg ya diad direksion ya mainomay ya inspeksionan.
(4) Paradbalbuladiad nengneng na welded connections, no ag nayarin usaren so blind plate pressure test, say conical seal odino O-ring seal et nayarin usaren parad pressure test. (5) Ipulisay so dagem na balbula anggad posible legan na hydraulic test.
(6) Say pressure et nepeg ya kalkalnan itagey legan na test, tan ag naabuloyan so maksil tan biglan pressureization.
(7) Say karukey na strength test tan sealing type test et kaslakan ya 2-3 minuto, tan saray importantin tan espisyal ya balbula et nepeg ya manbayag na 5 minuto. Say panaon na panagsubok parad saray balbula ya melag so diametro to et nayarin mas antikey, tan say panaon na panagsubok parad saray balbula ya angkakabaleg so diametro to et nayarin mas andukey met. Legan na test, no walay panduaruwa, nayarin palaknaben so oras na test. Legan na strength test, manpapasnok odino manpapasnok sobalbulaag naabuloyan so laman tan bonnet. Say sealing test et maminsan labat ya gagawaen parad inkalapaganbalbula, tan mamidua parad saray safety valve, high-pressurebalbulatan arum niran importantinbalbula. Legan na test, walay daiset ya leakage ya naabuloyan parad saray ag-importantin balbula ya abeba so presyon tan baleg so diametro tan saray balbula ya walay totontonen ya mangiter na leakage; lapud nanduruman kakaukolanen parad saray balbula na pangkabilugan, balbula na istasyon na kuryente, balbula ed dayat tan arum niran balbula, saray kakaukolanen ed leakage et nepeg ya onia: Gawaen unong ed saray matukoy a totontonen.
(8) Say throttle valve et ag nepeg ya gawaen ed tightness test na closing part, balet nepeg ya gawaen so strength test tan tightness test na packing tan gasket. (9) Legan na pressure test, say puersa na pansara na balbula et naabuloyan labat ya isara na normal ya biskeg na laman na sakey a too; ag nayarin mangiter na puersa ed saray kagawaan a singa say lever (likud ed torque wrench). No say diametro na handwheel et mas baleg odino mipara ed 320mm, duaran totoo so nayarin mankimey a saniiba. pansara.
(10) Parad saray balbula ya walay selyo ed tagey, say pakete et nepeg ya ekalen parad subok no kasin malet. Kayari na pangisara ed tagey a selyo, nengnengen no walay onlelereg. No manguusar na gas bilang test, nengnengen no walay danum ed kahon na palaman. No gagawaen so packing tightness test, say tagey a selyo et ag nayarin walad masimpit a posisyon.
(11) Parad antokaman a balbula a walaan na kagawaan ed panagmaneho, sano susuboken so inka-malet to, say kagawaan a panagmaneho so nepeg ya usaren pian isara so balbula tan gawaen so panagsukimat ed inka-malet. Parad manual ya ipapaandar ya kagawaan, say sealing test na manual ya akasara ya balbula et kaukolan met ya gawaen.
(12) Kayari na strength test tan tightness test, say bypass valve ya inyan ed manunan balbula et nepeg ya suboken parad biskeg tan inka-tight na manunan balbula; no nalukasan so mansara a parte na manunan balbula, nepeg met ya lukasan itan unong ed satan.
(13) Legan na panagsukimat ed biskeg na saray balbula ya cast iron, i-tap so laman na balbula tan say sakbong na balbula panamegley na kampanilya ya gansa pian nanengneng no walay onlelesa.
(14) No nasubok so balbula, likud ed saray plug valve ya mangiiter na larak ed sealing surface, saray arum ya balbula et ag nayarin suboken so sealing surface na larak.
(15) Legan na pressure test na balbula, say pressing force na blind plate ed balbula et nepeg ya aliwan baleg, pian napaliisan so deformation na balbula tan naapektoan so test effect (no say cast iron valve et masyadon malet, naderal itan).
(16) Kayari na pressure test na balbula, say natipon a danum ed balbula et nepeg ya ekalen ed dugan panaon tan punasan ya malinis, tan nepeg met ya gawaen so test record.
In TWS Valve, nipaakar ed manunan produkto mi, say soft seated butterfly valve, kaukolan ya awiten so high pressure seat tightness test. Tan say test medium et danum odino gas, tan say temperatura na test medium et walad baetan na 5°C~40°C.
Tan say ontumbok ya panagsukimat et say inka-malet na shell tan say performance na balbula.
Say gagala to et pian nakumpirma na test so inka-leak tight na shell kaiba lay panag-seal na operating mechanism sumpad internal pressure.
Legan na proseso na test, kaukolan tayon imanoen ya say test fluid et nepeg ya danum.
Tan say disc na balbula et nepeg ya walad medyo lukas a posisyon. Saray koneksion ed sampot na balbula et nepeg ya na-blanko tan amin ya abut et napano na danum ya test. Say pressure ya nibaga ed 1.5 times na PN et nepeg ya iyaplika ed danum ya nasubok.
