Izimo ezidingekayo zokukhethwa kwabalandeli

2025-08-08

Ukukhetha abalandeli kudinga ukwahlulela okuphelele okususelwa kwizimo zokusebenzisa, izici eziphakathi, izidingo zokusebenza, njll.

Nazi izinyathelo ezithile namaphuzu asemqoka:

I. Chazela Izidingo Eziyisisekelo: Okokuqala, gxila kumapharamitha amabili amakhulu we-'istflow 'kanye' nengcindezi '

Lesi yisisekelo sokukhethwa, okudinga ukubalwa noma kunqunywe ngokususelwa ezimweni zangempela:

- I-Airflow (Q): Ivolumu yegesi edinga ukuthuthwa ngesikhathi seyunithi ngayinye (e.g., M3 / H, M3 / Min).

Isibonelo: I-WorksWOP Vendawotation idinga ukubalwa okusekelwe kwivolumu yokusebenzela kanye ne-Air Change Rate (Airflow = I-Workshop Voluvor Izinga lokushintsha komoya); I-Boiler Draft idinga ukuzimisela ngokuya ngenani lomoya odingekayo ukuze uthole ukuhlanganiswa kwamafutha.

- Ingcindezi (P): Ukumelana okudinga ukunqotshwa lapho kudluliselwa igesi (e.g., Pa, KPA).

Kubandakanya ukumelana namapayipi (ukumelana kwasendaweni kusuka ku-bends, ama-valves, njll. + Ngokuvamile - ukumelana nobude bepayipi) kanye nokuvinjwa kwemishini (njengokuhlunga ukushisa, okudingeka kulinganiswe ngokumelana namafomula wokumelana noma idatha ye-empirical.

II. Hlanganisa izici eziphakathi: khipha izinhlobo ezingahambelani

Uhlobo lwegesi Medium ngqo luthinta uhlobo lwabathandi abakhethwe, oludinga ukunakwa okukhethekile ku:

Ukuhlanzeka okuphakathi:

- Umoya ohlanzekile (njengomoya omncane wehhovisi): ungakhetha abalandeli be-centrifugal, abalandeli be-axial, izindleko eziphansi.

- Iqukethe uthuli / izinhlayiya (njengokususwa kothuli lwami, Ukuhamba ngokomungo)

- Iqukethe amagesi awonakalisayo (njengegesi yamakhemikhali): Khetha izinhlobo ezingamelana ne-corrosion (ezifana nabalandeli bezinto ezibonakalayo ze-fiberglass, izingxenye zensimbi engagqwali).

Ukushisa okuphakathi:

- Izinga lokushisa elijwayelekile (≤80 ℃): Abalandeli abajwayelekile bangasetshenziswa.

- Ukushisa okuphezulu (njengogesi we-boiler flue, ukuhanjiswa komoya okushisayo, 00-400 ℃): Khetha abalandeli abangavimbela izinga lokushisa (njengabangenzi abenziwe nge-alloys ephezulu kakhulu, ama-motors afakwe nezinhlelo zokupholisa).

Ukuvutha okuphakathi nokuqhuma:

- Njenge-methane, igesi, njll.: Kufanele ukhethe abalandeli bobufakazi bobufakazi (ukwelashwa kobufakazi bokuqhuma kwemoto, shintsha, njll.

III. Kususelwa kwizici zesehlakalo: Izinhlobo zomdlalo fan

Abalandeli abahlukahlukene banezimpawu ezihlukile 'ze-Airflow-Pressures', ezidinga ukufaniswa nezidingo ze- 'airflow-trussures' zesigameko:

- Abalandeli be-Axial: Ilungele 'ukuhamba komoya okuphezulu, izingcindezi eziphansi' izimo '(ingcindezi imvamisa i-≤5kpa, i-airflow ingafinyelela amashumi ezinkulungwane ze-M3 / H).

Isibonelo: I-Workwork Veriation ephelele, umoya omncane we-tower, umoya ongaphansi komhlaba ongaphansi komhlaba nendawo yokufaka umoya (udinga ukuhambisa ngokushesha amanani amakhulu omoya, ukumelana okuncane).

Abalandeli be-Centrifugal:

- I-Single-Stage centrifugal fan: Ilungele i-'Med Meastflow, ingcindezi ephakathi '(ingcindezi engu-5-15kpa), njengabalandeli bokuthenga, ukuphefumula kwekhishi, umoya omncane wefektri omncane.

- I-Multi-Stage centrifugal fan: Ilungele i- 'Low Airflow, ingcindezi ephezulu' (ingcindezi ≥1pa, idlula i-100kpa), okudluliselwa kwe-pipeline ephezulu, ukuhanjiswa komoya omncane wegesi, umoya omncane osezingeni eliphezulu.

Ezinye izinhlobo ezikhethekile:

- Izimpande ze-Blower: Ingcindezi ephezulu (kuze kufike ku-200KPA nangaphezulu), Ukugeleza okuzinzile, okulungele ukugeleza kwendle okuqhubekayo ', kepha umsindo ophakeme), kepha umsindo uphakeme kakhulu.

- I-Flow-Flow Fan: Phakathi kwe-axial ne-centrifugal, ukugeleza komoya okulinganiselayo, okulinganiselayo kanye nengcindezi, efanelekile yokungena komoya omncane ophakathi nendawo noma umoya omncane we-shaft).

Lungiselela imininingwane yokukhethwa: Ukusebenza kahle kokulinganisa nokusebenziseka

- Ukusebenza kahle kuqala: Khetha imodeli ngokusebenza okuphezulu kakhulu ezimweni zokuklama (ukugeleza komoya, ukucindezela komoya) 'Ukugwema imodeli enkulu, ukusebenza kwangempela, ukusetshenziswa okuphezulu, ukusetshenziswa okuphezulu kakhulu).

Ukufakwa nokulungiswa:

- Isikhala esinqunyelwe: Khetha amamodeli ahlanganisiwe (afana nabalandeli be-axial flow, abalandeli be-centrifugal encane); Uma ukufakwa ngaphakathi kwama-ducts kuyadingeka, abalandeli be-centrifugal ebekwe phansi bangakhethwa.

- I-Second Fornience: Phuka amamodeli anezingxenye ezisuswa kalula (njengokuklama okushukumisayo kwabangenzi

- Izidingo zomsindo
