4. Ulwakhiwo ebusika, uvavanyo loxinzelelo lwamanzi kubushushu obungaphantsi kwe-zero.

Isiphumo: Ngenxa yokuba ubushushu bungaphantsi kwe-zero, umbhobho uya kubanda ngokukhawuleza ngexesha lovavanyo lwe-hydraulic, nto leyo enokubangela ukuba umbhobho uqande kwaye uqhekeke.

Amanyathelo: Zama ukwenza uvavanyo loxinzelelo lwamanzi ngaphambi kokuba wakhe ebusika, kwaye ususe amanzi kumbhobho nakwivalvu emva kovavanyo loxinzelelo, kungenjalo ivalvu isenokugqwala, kwaye oku kunokubangela ukuba kubekho umkhenkce oqhekekileyo.

5. I-flange kunye ne-gasket yoqhagamshelo lombhobho azinamandla ngokwaneleyo, kwaye iibholithi zokudibanisa zimfutshane okanye zincinci ububanzi. I-rubber pad isetyenziselwa umbhobho wobushushu, i-double pad okanye i-integrated pad isetyenziselwa umbhobho wamanzi abandayo, kwaye i-flange pad iyaqhekeka kumbhobho.

Iziphumo: i-flange joint ayiqinanga, yonakele nokuba yingxaki yokuvuza. I-flange gasket ephumayo kumbhobho iya kwandisa ukumelana nokuhamba kwamanzi.

Imilinganiselo: Iiflanges zepayipi kunye neegaskets kufuneka zihlangabezane neemfuno zoxinzelelo lokusebenza koyilo lwepayipi.

Iigaskets zeflange zemibhobho yokufudumeza kunye namanzi ashushu kufuneka zibe ziigaskets zerabha ze-asbestos; Igasket yeflange yombhobho wokuhambisa amanzi kunye nokukhupha amanzi kufuneka ibe yigasket yerabha.

Ilayini yeflange ayifanele iqhume ingene kwityhubhu, kwaye isangqa esingaphandle kufuneka sijikelezwe siye kumngxuma webholti yeflange. Akukho pad ithambekileyo okanye iigasket ezininzi mazibekwe phakathi kweflange. Ububanzi bebholti edibanisa iflange kufuneka bube ngaphantsi kwe-2mm xa kuthelekiswa nomngxuma weflange. Ubude benati ephumayo yentonga yebholti kufuneka bube yi-1/2 yobukhulu benati.

6. Ugutyulo, amanzi emvula, imibhobho ye-condensate ayivalwanga, uvavanyo lwamanzi luya kufihlwa.

Iziphumo: Zingavuza, zibangele ilahleko kubasebenzisi. Ukugcinwa kwazo kunzima.

Amanyathelo: Uvavanyo lwamanzi oluvaliweyo kufuneka luhlolwe kwaye lwamkelwe ngokungqongqo ngokweemfuno. Lungcwatywe phantsi komhlaba, eluphahleni, phakathi kwemibhobho kunye neminye imijelo yamanzi amdaka efihliweyo, amanzi emvula, imibhobho ye-condensate, njl.njl., ukuqinisekisa ukuba akukho kuvuza.

7. Ukuvulwa nokuvalwa kwevalvu ngesandla, amandla agqithisileyo
Iziphumo: umonakalo wevalvu ekhanyayo, ubunzima buya kukhokelela kwiingozi zokhuseleko

Amanyathelo:

Ivili lesandla okanye isiphatho sevalvu yesandla senziwe ngokuhambelana nabasebenzi abaqhelekileyo, kuthathelwa ingqalelo amandla omphezulu wokutywina kunye namandla okuvala afunekayo. Ngoko ke abanakusebenzisa iilever ezinde okanye izandla ezinde ukuhambisa ibhodi. Abo baqhele ukusebenzisa iiwrenches kufuneka banikele ingqalelo engqongqo ukuba bangasebenzisi amandla amaninzi, kungenjalo kulula ukonakalisa umphezulu wokutywina, okanye ukwaphula ivili lesandla kunye nesiphatho. Vula kwaye uvale ivalvu, amandla kufuneka abe bushelelezi, angachukumisi ngamandla. Kwivalvu yomphunga, ngaphambi kokuba ivulwe, kufuneka ifudunyezwe kwangaphambili, kwaye i-condensate mayingabandakanywa, kwaye xa ivulwa, kufuneka icothe kangangoko kunokwenzeka ukuze kuthintelwe isiganeko sehammer yamanzi.

Xa ivalvu ivuliwe ngokupheleleyo, ivili lesandla kufuneka liguqulwe kancinci, ukuze umsonto ube phakathi kwe-tight, ukuze ungaphulukani nomonakalo. Kwiivalvu ezivulekileyo, khumbula indawo yesiqu xa ivuliwe ngokupheleleyo kwaye ivaliwe ngokupheleleyo ukuze uphephe ukubetheka embindini ongasentla xa ivuliwe ngokupheleleyo. Kwaye kulula ukujonga ukuba ukuvalwa ngokupheleleyo kuyinto eqhelekileyo na. Ukuba idiski iyawa, okanye inkunkuma enkulu ifakwe phakathi kwe-spool seal, indawo yesiqu sevalvu kufuneka itshintshe xa ivalvu ivaliwe ngokupheleleyo.

Xa umbhobho usetyenziswa okokuqala, kukho ukungcola okungaphezulu kwangaphakathi, ivalvu ingavulwa kancinci, ukuhamba ngesantya esiphezulu kwesixhobo kungasetyenziselwa ukuyihlamba, ize ivalwe kancinci (ayinakuvalwa ngokukhawuleza, ukuthintela ukungcola okuseleyo ukuba kungonakalisa umphezulu wokuvala), ize ivulwe kwakhona, iphindaphindwe kaninzi, ihlambe ukungcola, ize isetyenziselwe umsebenzi oqhelekileyo. Ngokwesiqhelo vula ivalvu, umphezulu wokuvala unganamathela kukungcola, kwaye kufuneka ihlanjwe icoceke ngale ndlela ingasentla xa ivaliwe, ize ivalwe ngokusesikweni.

Ukuba ivili lesandla okanye isiphatho sonakele okanye silahlekile, kufuneka sitshatiswe ngoko nangoko, kwaye asinakutshintshwa sisandla sepleyiti esiguquguqukayo, ukuze kuthintelwe umonakalo kwisiqu sevalvu kunye nokungaphumeleli ukuvula nokuvala, okubangela iingozi kwimveliso. Ezinye izixhobo, emva kokuba ivalvu ivaliwe ukuze iphole, ukuze iindawo zevalvu zinciphe, umqhubi kufuneka avalwe kwakhona ngexesha elifanelekileyo, ukuze umphezulu wokutywina ungashiyi umthungo ocolekileyo, kungenjalo, i-medium evela kumthungo ocolekileyo ihamba ngesantya esiphezulu, kulula ukuyitshabalalisa umphezulu wokutywina.

Ukuba ufumanisa ukuba umsebenzi unzima kakhulu, hlalutya unobangela. Ukuba ukupakisha kuqinile kakhulu, kunokuphumzwa ngokufanelekileyo, njengokugoba kwesiqu sevalvu, kufuneka kwazise abasebenzi ukuba balungise. Ezinye iivalvu, xa zivaliwe, inxalenye yokuvala iyandiswa bubushushu, nto leyo ebangela ubunzima ekuvulekeni; Ukuba kufuneka ivulwe ngeli xesha, ungayikhulula intambo yesigqubuthelo sevalvu ijika isiqingatha ukuya kujika kube kanye, ususe uxinzelelo lwesiqu, uze utsale ivili lesandla.
