Uhlelo Lwesiqandisi, uhlelo lwamanzi lokupholisa, uhlelo lwamanzi esiqandisayo kanye namapayipi okuvikela amanzi, ama-flanges, ama-valve, amaphampu aguqukayo kanye nezinto eziguqukayo, kuze kube sezingeni lokuwohloka, kuze kufike lapho umkhawulo wengozi kungenzeka.
1.Repair of deformation yasendaweni yepayipi
Ukuqeda into yoshintsho lwasekhaya, kuyadingeka ukuthola isizathu sokwakheka nokusebenza. Njengombhobho wokugcina onamakhaza odongeni ngokuqongelelwa komthwalo weqhwa okubangelwa ukonakala okuningi, kufanele kuqinise umsebenzi wokuqamba. Uma ipayipi lide kakhulu, ukuguquguquka okubangelwa yisikhala se-spacket noma i-hanger, ubakaki noma i-hanger kufanele andiswe. Uma i-deformation ingabi nkulu, ayithinti ukusetshenziswa okuqhubekayo, kungalinda ukuphelelwa amandla bese kulungiswa, kepha kufanele kuqinise umsebenzi wokuhlola nokulungisa. Uma ishubhu ligobile kakhulu, ingxenye egobile yeshubhu ingagawulwa ngemuva kokuthi esiqandisini ku-tube sithululiwe bese sifaka iRecotor ukuze sikulungele. Ukucindezela kuyadingeka ukuze kube futhi kancane, ungashayi nge-sledgehammer, futhi ipayipi eliqondile lixhumeke kwipayipi eligcwele.
2. Ukulungiswa kwemifantu yepayipi kanye nama-mainholes
Ukuqhekeka kanye nama-mainholes emishini akukukhulu, ngokuvamile sebenzisa indlela yokulungisa yokulungiswa. Uma ukuvuza kwe-ger welding, ukuvuza kwe-welding akufanele kube ngaphezu kwezikhathi ezi-2, noma kufanele kuthathelwe indawo ukubhekana nepayipi. Lapho i-welding iphuzu lokuvuza, kwenqatshelwe ukusebenza emvelweni enesiqandisi esikhulu.
3. I-Flange averhaul
1) Bheka ukulayisha kwama-bolts ekuxhumeni kwe-flange, uma ekhululekile, qinisa amantongomane ngokulinganayo ngeSpanner ukwenza umfaniswano wamandla, kepha akufanele kube qine. Uma ama-bolts ekhubazekile noma acocekile ngokungathi sína, ama-bolts amasha kufanele athathelwe indawo.
2) I-asbestos gasket ku-Flange uxhumano iyavutha noma yashiswa, okuholela ekulahlekelweni kwekhono lokubekwa uphawu, futhi kufanele ithathelwe indawo nge-gasket entsha. Ngaphambi kokufaka esikhundleni se-gasket entsha, i-gasket yasekuqaleni kufanele ichithwe i-paraffin ukubheka ukuthi umugqa wokubopha we-flange ugcwala noma wonakalisiwe. Uma kungekho nkinga ingathathelwa indawo nge-gasket entsha, ukuqina kwe-diagonal Uniform of the Flange Bolts kungaba. Uma indawo evuthayo ye-flange ingaphansi kokulimala okungathi sína noma ukubekwa uphawu komugqa, ungafaka esikhundleni se-flange noma sokulungisa okusha bese ufakwa ku-gasket entsha ukuvikela ukusetshenziswa kokuvuza.
3) Umthungo we-welding akaqinile, kufanele alungiswe insimbi.
4) Uma i-welding ibangela ukuba i-flange ibe yi-warp futhi ingahlangabezani nezidingo zemihlangano, kufanele iguqulwe futhi icutshungulwe noma ithathelwe indawo.
5) Esezinhlelweni zokufakwa, uma umugqa we-Flanses Center akafani, uhlaka lwaso lokuxhumana akulona umfaniswano, ipayipi kufanele linqunywe futhi liphinde laqunjelwa.
4. Ukulungiswa kwe-valve
1) Ukubuyiselwa kokupakisha. Iqhaza eliphambili lokupakisha ukuvikela impahla yomsebenzi eceleni kwe-valve stem axiage ukuvuza bese usetha. Uma kwenzeka ukuvuza okuncane, kungaqinisa indlala yokupakisha, njengokuvuza akunakukhishwa, kufanele kuthathe indawo yokupakisha. Ukufakwa esikhundleni kwesiqu se-valve kumele kukhishwe ku-Screw kuze kube sekupheleni, nge-PIN yokupakisha kuya kokupakisha okudala ngaphandle, bese ulungele ukukopela ukupakisha okusha ngokuhlelekile, bese uqinisa indlala.
2) Lungisa i-spool. Ezindaweni zokufaka umoya kanye namaphrojekthi weqandisini, lapho ububanzi be-valve, i-spool incike engxenyeni yophawu lwepulasitiki lwe-alearined noma lwe-fluorine. Umhlane we-spool ubuye ube nesendlalelo se-aloy enamathiselwe, ukuze kuthi lapho i-valve squem ikhishwe esimweni esingezansi, ingabeka uphawu lokuqukethwe ngaphandle kwesiqu se-valve.
Lapho i-valve ihlakazeka, qala ngokuqondisa isiqu se-valve ukuze ukhiphe isidina, bese ubeka esikhundleni se-alloy ye-aloy, futhi ngasikhathi sinye, isihlalo se-valve kufanele futhi sibe yindawo, ukuze i-spool nesihlalo se-valve nomunye.
Ngensimbi encane ye-cast cast noma i-brass valve spool, uphawu lwale valve konke ukuthembela emgqeni wokuxhumana ngensimbi ukuthola, okubizwa ngokuthi yi-Lineal Seal. Ngoba uphawu lwentambo, futhi ngenxa yalokho isihlalo se-valve kanye ne-spool kufanele kube nomhlaba ngokucophelela ukuze uthole umphumela wokufaka uphawu ogculisayo.
Ukulungiswa kwe-valve kuqediwe, kufanele kube ngokuya ngezidingo ezifanele zokuhlolwa komoya.
Uhlelo lweqandisini olungiswe ngalo i-valve yezokuphepha nalo lufana nalokhu okungenhla, kepha ngenxa ye-alloy ethambile, imvamisa ngenxa yokucindezelwa kanye nesenzo se-valve yangempela ngemuva kwesikhathi, lapho ingcindezi yehlela engcebeni yokuvala, ivaliwe. Ukuze unqobe lesi sici, eminye imikhiqizo iye yathathelwa indawo ngeNickel-Chromium-Titanium Alloy (Hard) Alloy, noma nge-polytetrafluoroomyleneene esikhundleni salokho.
