To ano kufefetedza hurongwa zvawanzwa zvinodiwa. The kunaka kwayo kugadzwa kunobva nyaradzo uye kuchengeteka kwevanhu mukati meimba. Saka, asati nokurongwa kufefetedza mainjiniya kuita nomazvo kukarukureta pakati parameters ayo.

Round mhepo ducts pamusoro kwakakurudzira hwendarira zvinowanzoshandiswa zvinangwa dzakadaro maindasitiri uye mhuri zvinhu. Izvi imhaka yavo chaiyo maitiro. The kukwezva ducts izvi zvinofanira kukurukurwa zvizere.

Pakusarudza mutsinga dzinofamba nemukaka

Mutsinga dzinofamba nemukaka - ane chinhu of kufefetedza wemuTesitamende muchimiro bhokisi. It vanotora chikamu zvakananga achiparadzira mhepo makore uye mukutsinhana dzavo kwokunze kwezvakatipoteredza. muitiro uyu sezvingatarisirwa kana forcedly (achishandisa compressors) zvingaitika.

The kunyatsoshanda kunobva mhando kufefetedza sepombi, maitiro avo. Kushomeka dhayamita kana kukodzera zvinhu kuchaderedza kukurukurirana mukwaniso, kuti chidzoke nemhepo ruzha.

Round mhepo ducts akagadzirwa kwakakurudzira simbi anoshandiswa kakawanda kupfuura vamwe. Izvi imhaka unhu hwavo uye zvivako. Zvinokosha parameters zvigadzirwa dzakadaro kuomarara-sectional dhayamita, chimiro, mhando zvinhu, uye inobudisa yeimwe ose STRUCTURAL zvinhu.

Kuti vhendi pombi zvinodiwa ano, vari anogadzirwa maererano GOST 19904-90.

Zvinoitwa zvinhu

Air ducts ose dzeraundi muchinjikwa chikamu chakagadzirwa kwakakurudzira simbi, kunoda kuti GOST muchina kana Chinyorwa kugadzira, zvino mukuru kudiwa. Vari zvakavakwa kunyorwa jira.

Kuburikidza kushandiswa zvakadaro zvakasiyana siyana kwakakurudzira simbi anogona kuzadzisa kamari aerodynamic nemishonga. Installation mishonga iri nyore. Flange nokuti kumativi mhepo mutsinga dzinofamba nemukaka yakagadzirwa kwakakurudzira simbi rinoshandiswa zvishoma kazhinji pane munyatso.

Kubva yakanaka-leaved preform Inogona ducts kumativi uye rectangular chimiro chipi chikamu. Term kushanda mishonga kubva zvinhu izvi kusvikira makore 10. Galvanizing haisi pasi ngura. Inogona nyore zvifambiswe uye yakaiswa pamusoro yacho.

mhando

tenderera ducts dzakagadzirwa kwakakurudzira simbi marudzi akasiyana siyana, zvichienderana kupatsanura vamwe zviratidzo.

By mhando musono chubhu anogona welded kana spiralnonavivnye. Greater Kuvimbika anosiyana kutanga. chimiro chavo kunokonzera dzokuwedzera Rigidity uye rakavimbika mutsinga dzinofamba nemukaka.

Kirasi arambe achirema uye kuvimbika zvinhu zvive N (zvikukutu) uye N (romuzvarirwo). Muchiitiko chokutanga, nezvibereko angakudzivisai kumanikidzwa 1,4 kPa. Vanogona iiswe ari kwakavakirwa, ayo nemupristi moto kana kuputika pangozi inozivikanwa. Mukuvaka kwakajairika akashandisa boka H ducts

Zvikwepa Production spiralnonavivnyh

Spiralnonavivnye pamusoro ducts akagadzirwa kwakakurudzira simbi dzinovhunura 137 mm paupamhi. It spirals uye rinobatanidza micheto norudzi nokukiya fastener. The musono pamusoro chigadzirwa anogara kunze.

The dhayamita of rapera mutsinga dzinofamba nemukaka kunoenderana kwakakurudzira simbi billet ukobvu. Nokuti zvinhu zvikamu 150-350 mm inodiwa zvinhu 0.55 mm. Kana nenyere dhayamita kunodiwa 360-800 neMM, pakukora simbi wayo gadzira kuva 0,7 mm. The widest-Chikamu muchinjikwa ari kufefetedza kukurukurirana 850-1250 mm. Kwakakurudzira jira Saka tinofanira kuva Ukobvu 1 mm.

Factory Kugadzirwa chendangariro hurukuro pamusoro nenyere zvinhu pamusika pane 3-6 m. Kana mutengi zvakafanira Gomo negadziriro uchishandisa imwe mutsinga dzinofamba nemukaka urefu, zvigadzirwa vakaita arayire.

Properties spiralnonavivnyh pombi

Popularity akauya zvigadzirwa nokuda unhu hwavo. Kana mukugadzira munhu zononoka musono ducts zviri muchikamu dzeraundi vemuchinjikwa kwakakurudzira simbi ave simba. Ribbing Rigidity, uye dzakaonda Pepa simbi zvigadzirwa kunopa nyore.

Dhigirii Chokudzivirirwa ari pombi dzaimirirwa marudzi P. majoini vari mberi kupatsanurwa pamwe silicone sealant.

Nemhaka iyi unhu kugadzwa zvinhu zvakadai zviri nyore uye haatarisiri vakawanda yeimwe. Nokuti nokurongwa kufefetedza yezvinhu zvinoita kushandisa pombi M kusvika 12 refu.

Mhepo kuti ichipfuura kukurukurirana kwakadaro, mberi vakamonyanisa. Izvi anomupa kumhanyisa uye kunoderedza ruzha mumatunhu.

Welded pombi vavo kugadzirwa

Mukugadzira longitudinal kufefetedza gadziriro kunosanganisira kuda micheto jira simbi achishandisa mbambo kana flange.

For mureza kukura nokuveza papepa zvinhu kwaita. Kana kudiwa ariko kubudisa kwakakurudzira simbi ducts nevamwe parameters, kuti akachekwa akaita manually kushandisa chinokosha michina.

Mushure kucheka workpiece zvasvika mabhanzi. Haaruki mashoko kuva chubhu yacho achida dhayamita. Uyezve peta varara inosvika chigayo. The longitudinal pamuuyo mutsinga dzinofamba nemukaka zvakaipa. Nhindi vanotarisana pasi pamwe yose kureba.

By nzira iri vakawana pfupi nyere 1.5-2.5 m. Ungano zvigadzirwa izvi kushandisa dzakasiyana-siyana mune nyaya.

Zvakanakira longitudinal welded pombi

Kana tikaenzanisa ari welded dzeraundi ducts akagadzirwa kwakakurudzira simbi pamwe rectangular mhando dzavo, tsanangudzo yokutanga ndiyo iri isingadhuri. Vanonyanya "kunyarara", vane aerodynamics nani. Ndivo nyore kuisa kupfuura rectangular mutsinga dzinofamba nemukaka marudzi.

Asi kana tikaenzanisa pamwe spiralnonavivnymi pombi, welded nemarudzi kuisa dzakaoma. Ivo anoda kuti zvimwe kubatana, t. To. Kureba nyaya kwakadai zviduku.

Naizvozvo, pakuberekwa kutsva of kufefetedza ari private imba inoshandiswa welded pombi. Ivo isingadhuri. Asi zvakawanda spiralnonavivnye ducts zvinoshandiswa maindasitiri runyararo. Vashoma kwokubatana kuitwa, nani pakuberekwa kutsva hurongwa.

Fittings

Kuti dzokai, bazi, kana kuchinja, kuti kwakakurudzira simbi kubudisa dzeraundi mutsinga dzinofamba nemukaka moldings. Vanogona kuva diameters siyana uye vanosarudzwa maererano muchikamu muchinjikwa ari nyere nokuda kufefetedza.

Zvinhu zvarakanyorerwa kukura uye azere hurongwa chokugadza zvinosanganisira zvinhu zvakadai: Tees, Bends, amburera, matai, kuchinja, Bends, uye muchinjikwa netayi. Zvinoitika kana iwe kuisa kufefetedza yakaoma magadzirirwo rinoshandiswa yaipedzerwa zvinopfuura chinoshamisira zvigadzirwa kupfuura pombi pachavo.

Naizvozvo, kunaka kugadzirwa kwavo hakusi kukosha sezvo mhepo ducts. The majoini duku achava hurongwa, nani. Majoini pamusoro nguva kuunganidza guruva uye ungwandangwanda. Naizvozvo, zvikuru wakatsetseka pamusoro mukati, zvikuru hunogara zvichava upenyu hurongwa.

Zvaakanga familiarized pamwe zvinhu zvakadai kunhivi ducts zvakaitwa kwakakurudzira simbi, zvinganzi kwakagumisa kuti zviri zvikuru nevakawanda hurongwa. mutengo wayo uye chokupika uvagadzirire kudiwa kuisa siyana kufefetedza enyika. Nokuti mumwe mhando nzvimbo unofanira kusarudza zvakasiyana siyana pombi.
