4. Ukwakhiwa ebusika, ukuhlolwa kwengcindezi yamanzi ekushiseni okungaphansi kwezinga-zero.

Umphumela: Ngenxa yokuthi izinga lokushisa lingaphansi kwezinga-zero, ipayipi lizoqina ngokushesha ngesikhathi sokuhlolwa kwe-hydraulic, okungabangela ukuthi ipayipi liqine futhi liqhekeke.

Izinyathelo: Zama ukwenza ukuhlolwa komfutho wamanzi ngaphambi kokwakha ebusika, bese ususa amanzi epayipini kanye nevalvu ngemva kokuhlolwa komfutho, ngaphandle kwalokho ivalvu ingase igqwale, futhi okubi kakhulu kungaholela ekuqhekekeni okubandayo.

5. I-flange kanye ne-gasket yokuxhumeka kwephayiphi akunamandla ngokwanele, futhi amabhawodi okuxhuma amfushane noma amancane ububanzi. I-rubber pad isetshenziselwa ipayipi lokushisa, i-double pad noma i-integrated pad isetshenziselwa ipayipi lamanzi abandayo, bese i-flange pad iphuka ingene ephayiphini.

Imiphumela: i-flange joint ayiqinile, yonakele ngisho noma ivuza. I-flange gasket ephuma epayipini izokwandisa ukumelana nokugeleza.

Izinyathelo: Ama-flange nama-gasket amapayipi kumele ahlangabezane nezidingo zomfutho wokusebenza komklamo wamapayipi.

Ama-gasket e-flange yamapayipi okushisa namanzi ashisayo kufanele abe ama-gasket e-asbestos enjoloba; I-gasket ye-flange yepayipi lokuhambisa amanzi nelokukhipha amanzi kufanele abe yi-gasket yenjoloba.

I-liner ye-flange akufanele iqhume ingene epayipini, futhi indilinga engaphandle kufanele ijikelezwe iye emgodini we-bolt we-flange. Akukho pad ethambekele noma ama-gasket amaningana okufanele abekwe phakathi kwe-flange. Ububanzi be-bolt exhuma i-flange kufanele bube ngaphansi kuka-2mm uma kuqhathaniswa nomgodi we-flange. Ubude be-nut ephumayo yenduku ye-bolt kufanele bube yi-1/2 yobukhulu be-nut.

6. Amapayipi endle, amanzi emvula, ama-condensate awakwenzi ukuhlolwa kwamanzi avaliwe azofihlwa.

Imiphumela: Kungase kuvuze, futhi kubangele ukulahlekelwa ngumsebenzisi. Ukulungisa kunzima.

Izinyathelo: Ukuhlolwa kwamanzi avaliwe kufanele kuhlolwe futhi kwamukelwe ngokuqinile ngokwezincazelo. Kungcwatshwe ngaphansi komhlaba, ophahleni, phakathi kwamapayipi nezinye indle ezifihliwe, amanzi emvula, amapayipi e-condensate, njll., ukuqinisekisa ukuthi akukho ukuvuza.

7. Ukuvulwa nokuvalwa kwe-valve ngesandla, amandla amakhulu
Imiphumela: ukulimala kwevalvu elula, okunzima kuzoholela ezingozini zokuphepha

Izinyathelo:

Isondo lesandla noma isibambo sevalvu esetshenziswa ngesandla sakhiwe ngokuvumelana namandla avamile abasebenzi, kucatshangelwa amandla endawo yokuvala kanye namandla okuvala adingekayo. Ngakho-ke awukwazi ukusebenzisa izibambo ezinde noma izandla ezinde ukuhambisa ibhodi. Labo abajwayele ukusebenzisa ama-wrenches kufanele banake kakhulu ukuthi bangasebenzisi amandla amaningi, ngaphandle kwalokho kulula ukulimaza indawo yokuvala, noma ukuphula isondo lesandla nesibambo. Vula futhi uvale ivalvu, amandla kufanele abe bushelelezi, hhayi ukushaya okunamandla. Kwivalvu yomusi, ngaphambi kokuvula, kufanele ifudunyezwe kusengaphambili, futhi i-condensate kufanele ikhishwe, futhi lapho ivulwa, kufanele ihambe kancane ngangokunokwenzeka ukuze kugwenywe isimo sesando samanzi.

Uma ivalvu ivuliwe ngokugcwele, isondo lesandla kufanele libuyiselwe emuva kancane, ukuze intambo ibe phakathi kwe-tight, ukuze ingalahlekelwa umonakalo. Kumavalvu avulekile, khumbula indawo yesiqu lapho ivuliwe ngokugcwele futhi ivaliwe ngokuphelele ukuze ugweme ukushaya isikhungo esifile esiphezulu lapho ivuliwe ngokugcwele. Futhi kulula ukuhlola ukuthi ukuvalwa okuphelele kuyinto evamile yini. Uma idiski iwa, noma imfucumfucu emikhulu ifakiwe phakathi kwe-spool seal, indawo yesiqu sevalvu kufanele ishintshwe lapho ivalvu ivaliwe ngokuphelele.

Uma ipayipi lisetshenziswa okokuqala, kuba nokungcola okwengeziwe kwangaphakathi, ivalvu ingavulwa kancane, ukugeleza okusheshayo kwe-medium kungasetshenziswa ukuyihlanza, bese ivalwa kancane (ayikwazi ukuvalwa ngokushesha, ukuvimbela ukungcola okusele ukuthi kulimaze indawo yokuvala), bese ivulwa futhi, iphindaphindwe kaningi, ihlanza ukungcola, bese ifakwa emsebenzini ojwayelekile. Ngokuvamile vula ivalvu, indawo yokuvala ingase inamathele kokungcola, futhi kufanele ihlanzwe ngendlela engenhla uma ivalwa, bese ivalwa ngokusemthethweni.

Uma isondo lesandla noma isibambo sonakele noma silahlekile, kufanele siqondaniswe ngokushesha, futhi asinakushintshwa ngesandla sepuleti esiguquguqukayo, ukuze kugwenywe umonakalo esiqwini sevalvu kanye nokwehluleka ukuvula nokuvala, okuholela ezingozini ekukhiqizweni. Ezinye izinto, ngemva kokuba ivalvu ivaliwe ukuze iphole, ukuze izingxenye zevalvu zinciphe, opharetha kufanele aphinde avalwe ngesikhathi esifanele, ukuze indawo yokuvala ingashiyi umthungo omuhle, ngaphandle kwalokho, indawo ephakathi nendawo evela kumthungo omuhle igeleza ngesivinini esikhulu, kulula ukuguguleka indawo yokuvala.

Uma uthola ukuthi umsebenzi unzima kakhulu, hlaziya imbangela. Uma ukupakisha kuqinile kakhulu, kungakhululeka kahle, njengokugoba kwesiqu se-valve, kufanele kwazise abasebenzi ukuthi balungise. Amanye ama-valve, esimweni sokuvalwa, ingxenye yokuvala inwetshwa ukushisa, okubangela ubunzima ekuvulekeni; Uma kufanele ivulwe ngalesi sikhathi, ungakhulula intambo yesembozo se-valve ngesigamu sokujika kube ukujika okukodwa, ususe ukucindezeleka kwesiqu, bese udonsa isondo lesandla.
