Iqoqo lomoya wokungenisa umoya wensimbi engagqwali owenziwe ngokwezifisoizidambisi-manzisebeqedile ukukhiqizwa okugcwele, ukuqedwa kwendawo kanye nokuhlolwa kwefektri, sebelungele ukuthunyelwa ezindaweni zephrojekthi zaphesheya kwezilwandle. Lokhu kulethwa kuhlanganisa osayizi abaningi, okuhlanganisa ama-damper amakhulu angenamakhanda i-DN1600 (PN1), i-DN400, i-DN315, kanye nama-damper asetshenziswa ngesandla i-DN225. Zonke izinhlaka eziyinhloko zenziwe ngensimbi engagqwali engu-316L ukuze kuhlangatshezwane nezimo zokusebenza zaphesheya kwezilwandle ezidingakalayo.

Njengoba zenziwe ngensimbi engagqwali engu-316L, lezi zi-damper zinikeza ukumelana okuhle kakhulu nokugqwala ngokumelene negesi yoketshezi kanye negesi egqwali, ezisetshenziswa kabanzi embonini yamakhemikhali, i-metallurgy, ukwelashwa kwegesi engcolile kanye nokungenisa umoya kwe-HVAC. Kumaphrojekthi aphesheya kwezilwandle anomswakama ophezulu kanye ne-acid kancane ye-alkali, insimbi engagqwali engu-316L imelana ngempumelelo ne-oxidation, yandisa isikhathi senkonzo futhi inciphisa imvamisa yokushintsha izingxenye ezisele endaweni.

I-damper enkulu engenamakhanda ye-DN1600 inesakhiwo esincane ngaphandle kwendlu yokushayela evelele. Ngesilinganiso sokucindezela se-PN1, ilawula ukuhamba komoya futhi ivala amapayipi amakhulu. Ama-damper amancane aphakathi nendawo e-DN400 kanye ne-DN315 asebenzisa ukwakheka okuhlanganisiwe ukuze kube lula ukufaka amapayipi. I-damper esetshenziswa ngesandla ye-DN225 isebenza ngaphandle kwe-actuator eyengeziwe ukuze kube lula ukulungisa ngesandla endaweni.

Iyunithi ngayinye idlule ekupholisheni kwendawo kanye nokuhlolwa okuqinile kokusebenza kokuvala, ukugxila kweshaft, ukuguquguquka kokujikeleza kanye nobukhulu beflange. Umklamo ongenamakhanda ugwema ukuqongelela uthuli futhi wehlisa izindleko zokulungisa. Ukuxhumeka kweflange kwenza kube lula ukuhlanganisa indawo ngokushesha. Ukushisela okuqinile kuqinisekisa ukushisela okubushelelezi nokuqinile ukuvimbela ukuvuza kwegesi nokuhambisana nezindinganiso zokuphepha zamaphrojekthi obunjiniyela baphesheya kwezilwandle.

Leli oda lokuthumela ngaphandle ngobuningi lifakazela ukuqashelwa kwamakhasimende omhlaba wonke kwama-damper ezimboni akhiqizwa eShayina. Sigxila kuma-valve okungenisa umoya angewona ajwayelekile, sisekela ukwenza ngokwezifiso usayizi, izinto kanye nohlobo lwe-actuator. Imibhalo ephelele yokuthumela ngaphandle efana nemidwebo yobuchwepheshe kanye nemibiko yokuhlola iyatholakala, ukuze kuhlinzekwe izixazululo zokuhambisa amanzi ezingabizi emhlabeni jikelele.
