Yiziphi izimo ezidingekayo zokuklama aisithando somlilo esishisayo? Nasi isingeniso esifushane kuwe:
1 Dizayina umthwalo wokushisa. Kufanele kube nemajini ethile phakathi komthwalo wokushisa nomthwalo wokushisa osebenzayo wesithando somlilo esishisayo, futhi le mashi ngokuvamile i-10% kuya ku-15%.
2 Izinga lokushisa lokuklama. Izinga lokushisa lokuklama lesithando somlilo sokudlulisa ukushisa linqunywa izinga lokushisa lokusetshenziswa kwalo, futhi kufanele liklanywe ngokubhekisela ezinhlinzekweni ezifanele ze-GB9222 "Ukubalwa kwamandla okuqala we-tube boiler yamanzi".
3 Ingcindezi yokuklama. Ukucindezela kokuklama kwamafutha okudlulisa ukushisa kufanele kube phezulu kancane kunokucindezela okukhulu kokusebenza, futhi akufanele kube ngaphansi kokucindezela kokuvula kwe-valve yokuphepha. Ingcindezi yokuklama yesithando somlilo sesigaba segesi yi-1.2 ~ 1.5 izikhathi zokucindezela kokusebenza; Ukucindezela kokuklama kwesithando somlilo sesigaba se-liquid kufanele kube izikhathi ezingu-1.05 ~ 1.2 ukucindezela; Umehluko wengcindezi phakathi kokungena nokuphumayo kwamafutha okudlulisa ukushisa esithandweni somlilo sesigaba soketshezi kufanele ube mkhulu kuno-0.15MPa (1.5kgf/cm2).
4 Izinga lokushisa lendawo yokungena nowoyela yokudlulisa ukushisa. Idizayini kufanele ibe ngokombono wakho kokubili umnotho nokuphepha, ukuklama umehluko ofanelekayo wokushisa wokusebenza kwamafutha ashisayo ohlelweni, futhi umehluko wokushisa kufanele ube ngaphansi kuka-30℃.
5 Izinga lokugeleza kwamafutha okudlulisa ukushisa epayipini. Dizayina izinga elithile lokugeleza kwamafutha ashisayo epayipini, kodwa hhayi ngenxa yokushisisa ngokweqile kwendawo kanye nokupheka, ingxenye evamile yemisebe yepayipi esebenzisa izinga lokugeleza elingu-2~4m/s, ingxenye yokugeleza kwepayipi isebenzisa izinga lokugeleza elingu-1.5~2.5m/s. Ukuzimisela kwalesi simiso kufanele futhi kucabangele ukumelana kwamafutha ashisayo epayipi kanye nezici eziqinisekisa ukugeleza okuthuthumelayo kwamafutha ashisayo epayipi. Izinga lokugeleza liphakeme lapho ububanzi bepayipi bukhulu. Ububanzi bepayipi buncane, izinga lokugeleza kufanele libe phansi.
6 Amandla ashisayo amaphakathi weshubhu yesithando somlilo. Idizayini idinga amandla okucwiliswa okuyisicaba kweshubhu yesithando somlilo ukuba abe phakathi kwebanga elithile, ukuze isithando somlilo esishisayo singashisi ngokweqile futhi indawo yokudlulisa ukushisa yeshubhu yesithando somlilo ingasetshenziswa ngokugcwele. Amandla okushisa ajwayelekile weshubhu yesithando somlilo esigabeni semisebe evamile ngu-0.084~0.167GJ/(m2.h), futhi amandla avamile okushisa eshubhu lesithando somlilo ezigabeni eziyisithupha ngu-0.033~0.047GJ/(m2.h).
7 Ukushisa kwentuthu yokuphefumula. Ngokwezinga lokushisa elisebenzayo lamafutha okudlulisa ukushisa asebenzayo, umehluko phakathi kwezinga lokushisa lokukhipha intuthu kanye nezinga lokushisa likawoyela wokudlulisa ukushisa lilawulwa kangcono ku-80 ~ 120 ℃, futhi izinga lokushisa lokukhipha intuthu lifaneleka ku-350 ~ 400 ℃, ukuze indawo yokushisa ye-convection ingabi mkhulu kakhulu. Ukuze kusetshenziswe amandla okushisa ngokugcwele, ukushisa kwalawa mazinga okushisa aphezulu entuthu ekhipha intuthu engafakwanga isithando somlilo esishisayo kufanele kumiswe idivayisi yokubuyisela ukushisa kwemfucuza ukuze kubuyiselwe futhi kusetshenziswe kabusha, ikakhulukazi isithando somlilo esishisayo esikhudlwana kufanele sicatshangelwe futhi sinakwe.
8 Wonke amapayipi nezinye izinto ezithinta uwoyela oshisayo kwenqatshelwe ngokuphelele ukuthi zenziwe ngezinsimbi ezingenayo insimbi nensimbi ekhonjiwe. Ama-flange nama-valve kufanele kube ama-valve ensimbi anomfutho wegazi ongu-2.5MPa (cishe u-25kgf/cm2) nangaphezulu. Izivalo kufanele zenziwe ngezinga lokushisa eliphezulu kanye nezinto ezimelana nowoyela. Sebenzisa ingxube ye-biphenyl yamafutha okudlulisa ukushisa, sebenzisa uxhumano lwe-mortise noma i-concave flange.
9 Isithando somlilo esishisayo kufanele sifakwe i-valve yokukhipha amanzi ephansi, futhi kuyadingeka ukukhipha impahla ukuze kuqinisekiswe ukuthi akukho uketshezi olusele olusele.
Ngakho-ke, uma udinga isithando somlilo esishisayo sekhwalithi ephezulu, ungabheki okunyeI-Jiangsu Yanyan Industries Co., Ltd.Sikulungele ukukusiza ngokuthenga kwakho futhi siqinisekise ukuthi uthola imikhiqizo engcono kakhulu yezidingo zakho zokushisisa.Xhumana nathinamuhla ukuze ufunde kabanzi mayelana neziko lethu likawoyela oshisayo futhi ubeke i-oda lakho.
