Zeziphi iindlela eziphambili zokufaka kunye nokugcina isango?

Njengesixhobo esiphambili sokulawula ukuhamba kwamanzi kwiinkqubo zemizi-mveliso ye-piholion System, ufakelo kunye nomgangatho wolondolozo weI-valves yesangoihambelana nokuzinza nokhuseleko lwenkqubo. Oku kulandelayo ziindlela eziphambili:

1. ISigaba sokufakela: Okokuqala, yenza uvavanyo kunye nonyango lwangaphambi kokuqinisekisa ukubaI-Palve yesangoImodeli, ireyithi yengcinezelo, isixhobo, kunye neemeko zokusebenza zihambelana, kwaye akukho monakalo wothutho. Coca i-piholine yokungcola, kunye nokwenza ubugcisa kunye novavanyo lwentshukumo yeemeko zokusebenza. Okwesibini, nikela ingqalelo kwicala kunye nesikhundla, faka ngokwemiyalelo yokutolo. I-valve ye-valve ethe nkqo kufuneka ibe yi-propendicular emhlabeni, kwaye utyekelo oluthe tye kufuneka ube ≤ 15 °. Indawo yokugcina indawo ye-handheel okanye umsebenzi we-actuator (≥ 300mm). Xa uqhagamshela kwaye ulungiso, unxibelelwano lweflethi kufuneka luhambelane nemingxunya ye-bolt kwaye iqiniswe ngamanqanaba emigangatho; Sebenzisa i-argon ar yels njengesiseko sonxibelelwano lwe-welding kwaye ngokuthe ngcembe lupholile. Okokugqibela, qhubeka nokulahla inkunkuma, vula kwaye uvale amaxesha ama-3-5, cinga ukuba ngaba iyazi, kwaye ijonge ukuvuza kwamanzi asezantsi okanye uxinzelelo.

2. Isigaba sesondlo: Uhlolo lwemihla ngemihla kufuneka ujonge i-vloves ye-vlove kunye ne-valve stem coaatings, irekhode inani kunye nexesha lokuvula nokuvalwa, kunye nokulungiswa ngokukhawuleza nakuphi na ukulungisa ukungasebenzi. Ngokwe-tybhuysetion kunye nokutywina, sebenzisa igrisi ephezulu kwi-valve qho ngenyanga, vala i-valve yesango ukuze unciphise i-valves yokutywina yetywina. Ukulungiswa rhoqo kufuneka kwenziwe kanye kwiinyanga ezi-6 ukuya kwezi-12 zeemeko eziqhelekileyo zomsebenzi kwaye kube kanye kwiinyanga ezi-3 kwiimeko zomsebenzi ezisebenzayo okanye zobushushu obungaphezulu. Ukuba indawo yokutywina inxitywe, i-valve stem igobile, okanye ukupakisha ivuza kudlula i-thement, kufuneka itshintshwe. Ngokuhambelana nengxaki, ukuba kukho ukuvuza ngaphakathi, iibhotile zinokuqina okanye zitywina zinokutshitshiswa. Ukuba kunzima, isitulo sevali sinokutshintshwa; Thoba i-valve stem kwi-arhente yokukhulula okanye ukonakala kwaye uyicoce xa ibambekile. Phantsi kweemeko zomsebenzi ezikhethekileyo, faka indibaniselwano yokwandiswa phantsi kweemeko zobushushu obuphezulu kwaye usebenzise izixhobo ezinganyangeki ngobushushu; Unyango lobushushu olusezantsi lwenziwa phantsi kweemeko zobushushu obuthathaka, kwaye isiqu esiphezulu sikhethiwe; Imithombo yeendaba ebomvu ifakwe izinto ezichasene ne-anti-slosion, ihlolwe rhoqo ngexabiso le-pH.

IZIKHOKELO ZOKUKHUSELEKA: Landela amanqaku okuhamba kwendlela yeI-Palve yesango; I-valve stem rate to ≤ ra0.8 μ m; Songa umzimba wevali okanye ukubonelela ngokhuseleko lwe-nitrogen ngaphambi kokuba i-welding. Ufakelo olusemgangathweni kunye nesondlo sesayensi sinokwandisa ubomi benkonzo yamasango, ngaphezulu kwe-50% kwaye unciphise amazinga okusilela. Kucetyiswa ukuba uphuhlise imigaqo kwaye uqeqeshe abaqhubi ngokuhambelana nencwadana yemigaqo.
