Guhitamo uburenganzira Umufana wa ATEX ntabwo ari ukugenzura agasanduku-ni ukwirinda gutwikwa mu bimera bivangwa n’umukungugu, kwirinda kunanirwa gukabije mu cyumba cyo gusiga amarangi, cyangwa kwemeza umwuka uhoraho aho methane yibanda hafi y’imipaka iturika. Twabonye ibikoresho byerekana abafana ba "ATEX-bahabwa" gusa kuvumbura-mugihe cyo gutangiza-ko moteri ya moteri itemewe kumatsinda ya gaze ya Zone 1, cyangwa ko ibikoresho byimuka bidashobora kwihanganira imyuka yuzuye silika yuzuye. Niyo mpamvu guhitamo bitangirana numubare wa kataloge, ahubwo nibibazo bitatu bidashobora kuganirwaho: Ni ubuhe buryo nyabwo bwo gutondekanya akarere? Ni ubuhe bushyuhe ntarengwa bwo gukora bwo mu kirere? Kandi ni ubuhe buryo bwo gukanika umufana azihanganira - kwangirika, gukuramo, gusiganwa ku magare, cyangwa byose uko ari bitatu?
Kuki icyemezo cya ATEX gisaba ibirenze ikirango
An Umufana wa ATEX igomba kuba yujuje ibyangombwa bibiri bisa: urwego rwo kurinda ibikoresho (EPL) ruhuye na zone (urugero: Ga kuri Zone 0, Gb kuri Zone 1), hamwe na gazi ihuza (IIC kuri hydrogen / acetylene, IIB kuri Ethylene, IIA kuri propane). Ariko icyemezo cyonyine ntabwo cyemeza imikorere yumurima. Mu mushinga umwe wo gutunganya, umufana yatsinze ikizamini cya ATEX kuri 25 ° C - ariko birananirana mugihe cyizuba cyatangiye mugihe ubushyuhe bwubuso bwarenze T4 (135 ° C) kubera igishushanyo mbonera cyo gukwirakwiza ubushyuhe budahagije. Kwubahiriza-kwisi bisobanura kugenzura icyiciro cyumuriro * mubihe byinshingano zakazi *, ntabwo ari laboratoire gusa. Bisobanura kandi kwemeza buri kintu cyose - gifite kashe, amaboko ya shaft, ndetse nugufunga-byashyizwe mubyemezo. Mubisanzwe dusuzumisha ibyemezo byubwoko bwa EC byerekana ibizamini mbere yo koherezwa. Nta bitekerezo. Nta na kimwe kidasanzwe.
Guhitamo Ibishushanyo birinda kunanirwa - Ntabwo byujuje ubuziranenge gusa
Umufana wemejwe birananirana niba iyubakwa ryayo rivuguruza ibidukikije. Suzuma ibi byemezo byemejwe:
- Impeller yibintu byingenzi kuruta igipimo cyumuvuduko uhagaze. Imashini ya aluminiyumu itera umukungugu wumukara wa karubone-ndetse byemewe na ATEX. Titanium cyangwa ibyuma bidafite ibyuma bikuraho izo ngaruka, ariko bisaba kuringaniza imbaraga zingana kugirango wirinde kwangirika kwatewe no kwinyeganyeza mubikorwa bikomeza 24/7.
- Kwishyira hamwe kwa moteri ntabwo gucomeka no gukina. Moteri yemewe na ATEX yashyizwe kumazu yabafana batabifitiye ibyemezo itesha agaciro inteko yose. Igice cyuzuye-harimo gutwara ibinyabiziga, kurinda, hamwe na base-bigomba kugeragezwa nka sisitemu imwe.
- Ingamba zo gufunga zisobanura kuramba. Ikidodo gisanzwe gifata umukungugu mu mezi make mumashanyarazi ya sima. Sisitemu nziza-yogusukura hamwe na inert ya gaz inert yongerera igihe cya serivisi 3-5 × muri zone nyinshi.
Twasimbuye abafana barenga 120 mumurage mumashanyarazi akoreshwa namakara aho gazi ya desulfurizasi yateje kwangirika byihuse kumashanyarazi asanzwe. Guhindukira kubakunzi ba centrifugal ebyiri-hamwe na epoxy-coating casings hamwe na Hastelloy-C276 yimura yagabanije amasaha atateganijwe kuri 78% - nta guhungabanya ubunyangamugayo bwa ATEX.
Customisation ntabwo ari Ibinezeza-Nuburyo bwonyine bwo guhuza Ukuri
Abafana ba ATEX hanze yububiko bakemura ibibazo byibitabo. Imbuga nyazo ntizikurikiza ibitabo. Ubwiherero bwa farumasi bwari bukeneye guhumeka biturika hamwe n urusaku rwa ≤25 dB (A) - ntibishoboka hamwe na moteri isanzwe ya radiyo. Igisubizo: ibicuruzwa byinyuma-bigoramye titanium impeller, umurongo wa acoustic winjiye muri volute, hamwe na moteri ya IE4 itaziguye ikuraho umukandara-wo gutwara ibyago. Igihe cyose cyo gutanga: ibyumweru 11. Undi mukiriya kumurongo wa acide sulfurike yasabye kurwanya igihu cya H₂SO₄ kuri 80 ° C mugihe agumana icyemezo cya Zone 1 IIB. Ibisanzwe bya epoxy bitwikiriye. Twakoresheje fluoropolymer itondekanye ibyuma bikozwe mucyuma hamwe na ceramic yometseho shaft - kandi twemeza ko coefficient zo kwagura amashyanyarazi zuzuye.
Custom ntabwo bivuze gutinda. Imashini zacu murugo, guhimba ibyuma, hamwe nimirongo iringaniza reka reka duhindure case geometrie, duhuze inlet / outlet flanges, duhuze ibyuma byerekana ubushyuhe, cyangwa twongereho ibyambu bya purge - byose nta gutinda kongera kwemeza, kuko dukora mubipaka byashizweho mbere.
Ibizaza nyuma ya fagitire igena umutekano-Ntabwo byubahirizwa gusa
Inyandiko numurongo wawe wambere wo kwirwanaho mugihe cyubugenzuzi cyangwa iperereza ryabaye. Buri Umufana wa ATEX kuva muri Zibo Hongcheng Fan Co., Ltd yoherejwe na dosiye yuzuye ya tekiniki: Icyemezo cyibizamini byo mu bwoko bwa EC, raporo y'ibizamini (kunyeganyega, urusaku, izamuka ry'ubushyuhe), ibyemezo by'ibikoresho, hamwe na moteri yihariye yo kwishyiriraho - ntabwo ari imfashanyigisho rusange. Dushyiramo QR-code yanditseho amazina ahuza ibishushanyo mbonera bigenzurwa na lisiti y'ibicuruzwa. Mugihe ikibanza cya peteroli muri Oman cyari gikeneye gusimburwa byihutirwa byatewe na firime yamashanyarazi yamenetse, itsinda ryacu ryubwubatsi ryasuzumye ibishingwe byari bihari, kwihanganira imiyoboro ya ductwork, hamwe na gride ya voltage ihuza - hanyuma yohereza ibitonyanga byasimbuwe nibintu byashyizweho mbere na VFD hamwe no kugenzura icyiciro. Nta gukeka. Nta murima wongeye gukora.
Umutekano ntugerwaho mugutangiza. Birakomezwa binyuze muburyo buteganijwe bwo kubungabunga, ibice bikurikiranwa, na ba injeniyeri bahagaze mucyumba cyawe cyo kugenzura mugihe cyo gutangira. Niyo mpamvu inkunga yacu ikubiyemo amahugurwa yihariye yo gusaba-ntabwo ari "uburyo bwo kuyifungura," ahubwo "uburyo bwo kubona ibyiciro byambere bitesha agaciro ahantu hafite ubushyuhe bwinshi muri Zone 2."
