Iringi yokupakisha engezansi ayihlali kahle, ukupakisha kuvuza kakhulu futhi kuguge umshini ojikelezayo wezinto zokusebenza. Kodwa-ke, lezi akuzona izinkinga uma nje zifakwe ngokunembile, izindlela zokulondoloza ezingcono kakhulu ziyalandelwa futhi ukusebenza kulungile. Ukupakisha kulungele izinhlelo zokusebenza eziningi zenqubo. Lesi sihloko sizosiza abasebenzisi ukuthi bafake, basebenzise futhi bagcine ukupakisha njengochwepheshe.

Ukufaka Okunembayo

Ngemva kokukhipha indandatho yokupakisha eye yakhathala ukuphila kwayo futhi yahlola ibhokisi lokugxusha, uchwepheshe uzosika futhi afake iringi yokupakisha entsha. Ukuze wenze lokhu, ubukhulu be-shaft ejikelezayo yemishini - ipompo - idinga ukulinganiswa kuqala.

Ukuqinisekisa usayizi ofanele wokupakisha, umuntu osika ukupakisha kufanele asebenzise i-mandrel engusayizi ofanayo ne-shaft ejikelezayo yemishini. I-mandrel ingenziwa kalula ngezinto ezitholakala esizeni, njengemikhono emidala, amapayipi, izinduku zensimbi noma izinduku zokhuni. Bangakwazi ukusebenzisa i-tape ukwenza i-mandrel ibe usayizi ofanele. Uma i-mandrel isethiwe, sekuyisikhathi sokuqala ukusika ukupakisha. Landela lezi zinyathelo:

1. Gcoba ukupakisha ngokuqinile eduze kwe-mandrel.

2. Usebenzisa ilunga lokuqala njengesiqondiso, sika ukupakisha nge-engeli engaba ngu-45°. Indandatho yokupakisha kufanele isikwe ukuze iziphetho zivumelane ngokuqinile lapho indandatho yokupakisha isongwe nge-mandrel.

Ngezindandatho zokupakisha ezilungisiwe, ochwepheshe bangaqala ukufakwa. Ngokuvamile, amaphampu eturbine ajulile aqondile adinga amaringithoni amahlanu okupakisha kanye neringi eyodwa yophawu. Ukuhlala kahle kwendandatho ngayinye yokupakisha kubalulekile ekusebenzeni okuthembekile. Ukufeza lokhu, isikhathi esiningi sichithwa phakathi nenqubo yokufaka. Kodwa-ke, izinzuzo zifaka ukuvuza okuncane, impilo ende yesevisi, kanye nokunakekelwa okuncane.

Njengoba kufakwa iringi ngayinye yokupakisha, amathuluzi amade nafushane futhi ekugcineni indandatho yophawu isetshenziselwa ukuhlalisa ngokugcwele iringi ngayinye yokupakisha. Gcoba amalunga eringi ngayinye yokupakisha ngo-90°, kusukela ngehora le-12 ezimpondweni, bese kuthi ngo-3 ezimpondweni, ngehora lesi-6, nangehora lesi-9.

Futhi, qiniseka ukuthi indandatho yophawu isendaweni ukuze uketshezi olushaywayo lungene ebhokisini lokugxusha. Lokhu kwenziwa ngokufaka into encane embotsheni yokuwasha kanye nokuzwa iringi yokuvala. Lapho ufaka indandatho yesihlanu neyokugcina yokupakisha, kuzosetshenziswa umlandeli wendlala kuphela. Umfaki kufanele aqinise umlandeli wendlala esebenzisa amaphawundi angama-25 ukuya kwangu-30 wetorque. Bese ukhulula ngokuphelele indlala futhi uvumele ukupakisha ukuthi kuphumule imizuzwana engama-30 kuya kwangu-45.

Ngemva kokuba lesi sikhathi sesidlulile, qinisa umunwe we-gland nut futhi. Qala iyunithi futhi wenze izinguquko njengoba kudingeka. Ukuvuza kufanele kukhawulelwe kumaconsi ayi-10 kuye kwayi-12 ngomzuzu iyintshi ngalinye lobubanzi bomkhono.

Ukuchezuka kwe-Shaft

Uma i-shaft ye-a iphampu ye-turbine ejulile kahle kuchezuka, kuzokwenza ukuthi ukupakishwa kokucindezela kuhambe futhi kulimaze. Ukuchezuka kwe-shaft ukugoba kancane kwe-pump shaft lapho isivinini se-impeller ephusha uketshezi singalingani kuwo wonke amaphuzu azungeze i-impeller.

Ukuchezuka kwe-shaft kungenzeka ngenxa ye-pump rotor engalingani, ukungahambi kahle kwe-shaft, nokusebenza kwepompo kude nendawo yokusebenza kahle kakhulu. Lokhu kusebenza kuzodala ukuguga kokupakisha ngaphambi kwesikhathi futhi kwenze kube nzima kakhulu ukulawula nokusebenzisa ukuvuza koketshezi olushaywayo. Ukwengeza i-shaft stabilizing bushing kungasiza ukunciphisa noma ukuqeda le nkinga.

Izinguquko Zenqubo Nokwethenjwa Kwebhokisi Lokufaka

Noma yiluphi ushintsho kuketshezi lwenqubo noma izinga lokugeleza lizothinta ibhokisi lokugxusha kanye nokupakishwa kokucindezelwa ngaphakathi kwalo. I-stuffing box flushing fluid kufanele isethwe futhi isetshenziswe ngendlela efanele ukuqinisekisa ukuthi ukupakisha kuhlala kuhlanzekile futhi kupholile ngesikhathi sokusebenza. Ukwazi ingcindezi yebhokisi lokugxusha kanye nemigqa yemishini kuyisinyathelo sokuqala. Kungakhathaliseki ukuthi usebenzisa uketshezi oluhlukile olushaywayo noma ukupompa uketshezi (uma luhlanzekile futhi lungenazo izinhlayiya), ingcindezi engena ebhokisini lokugxusha ibalulekile ekusebenzeni kahle nasekupakisheni ukuphila. Isibonelo, uma umsebenzisi ekhawulela ukugeleza kokumpompa nganoma yisiphi isikhathi nge-valve yokukhipha amanzi, ukucindezela kwebhokisi lokugxusha kuzothinteka futhi uketshezi olumpontshiwe oluqukethe izinhlayiya luzongena ebhokisini lokugxusha nokupakisha. Umfutho wokushaywa kwamanzi kufanele ube phezulu ngokwanele ukuze unxephezele noma yiziphi izimo ezimbi kakhulu ezingase zenzeke ngesikhathi sokusebenza kwephampu ye-turbine ejulile emile.

I-flushing ingaphezu nje koketshezi olugeleza lusuka kolunye uhlangothi lwebhokisi lokugxusha futhi luphumele kolunye uhlangothi. Ipholisa futhi igcobe ukupakisha, ngaleyo ndlela inwebe impilo yayo futhi inciphise ukuguga kwe-shaft. Iphinde igcine izinhlayiya ezidala ukuguga ngaphandle kokupakisha.

Isondlo Esikahle

Ukugcina ukwethembeka kwebhokisi lokugxusha, uketshezi olushaywayo kufanele lulawulwe ukuze kugcinwe ukupakisha kuhlanzekile, kupholile futhi kugcotshisiwe.

Ngaphezu kwalokho, amandla asetshenziswa umlandeli we-gland ekupakisheni kufanele alungiswe njengoba kudingeka. Lokhu kusho ukuthi uma ukuvuza kwebhokisi lokugxusha kungaphezu kwamaconsi ayi-10 kuye kwayi-12 ngomzuzu iyintshi ngalinye lobubanzi bomkhono, indlala idinga ukulungiswa. Uchwepheshe kufanele alungise kancane kuze kube yilapho kufinyelelwa izinga elifanele lokuvuza ukuze aqinisekise ukuthi ukupakisha akupakishwanga kakhulu. Uma indlala ingasakwazi ukulungiswa, kusho ukuthi impilo yokupakisha yephampu ye-turbine ejulile emile isiphelile futhi kufanele kufakwe iringi yokupakisha entsha.
