Ukuhamba ngeendawo zokusebenzela ezinobungozi: Isikhokelo esiBanzi kwi-Explosion-Proof Hoists

Izinto eziPhambili zeeNqaku zoQhobo-bubungqina

Izixhobo ezingqina ukuqhuma:

uBronzi weAluminiyam:

I-Aluminiyam yobhedu yi-alloy ye-aluminiyam eyaziwa ngokuxhathisa ukubola, ukuqhuba, amandla, kunye nobunzima.

Indawo yokunyibilika: 580-640 °C

Ubuninzi: 2.7-2.9 g/cm³

Usetyenziso oluqhelekileyo: Izindlu, iigwegwe, amatyathanga ezixhobo zombane ezingenoqhushumba

b. I-Beryllium Bronze:

I-beryllium bronze yi-alloy ye-beryllium enamandla angaqhelekanga, ukuqina, ukuqina, ukuhanjiswa, kunye nokuhamba kwe-thermal.

Indawo yokunyibilika: 930-980 °C

Ubuninzi: 2.1-2.3 g/cm³

Usetyenziso oluqhelekileyo: Izinto ezithanda ukutshisa kwisixhobo sombane esingaqhubi luqhushumbo, njengeegiya, iibholiti, iinati.

c. I-Stainless Steel:

Intsimbi estainless yintsimbi enealloyi ephezulu ekwazi ukumelana nokugqwesa, ukuxhathisa, kunye nokomelela.

Iimpawu ezithile ziyahluka ngokuxhomekeke kuhlobo kunye nokwakheka.

Umzekelo: I-304 insimbi engenasici (i-austenitic eqhelekileyo insimbi engenasici kunye nokuchasana nokugqwesa okulungileyo kunye nokusebenza) 316 insimbi engenasici (i-molybdenum insimbi engenasici kunye nokumelana okuphezulu kwe-corrosion, ngakumbi kwiindawo ze-chloride)

Usetyenziso oluqhelekileyo: Iibholiti, amandongomane, iibheringi zezixhobo zombane ezingenoqhushumba

Uyilo-bubungqina bokudubula:

Ithintela imixube yerhasi eqhumayo ekungeneni okanye ekubalekeni kwindawo ebiyelweyo enogqabhuko-dubulo.

Iquka ubuchule obahlukeneyo bokwahlula imithombo enokubakhona yokutshisa kunye nokuvala ugqabhuko-dubulo ngaphakathi kwendawo ebiyelweyo.

I-Common Explosion-proof Hoist Designs

Exd (Ubungqina bokudubula kothuli):

Isebenzisa indawo ebiyelweyo engatshiyo ukunqanda ugqabhuko-dubulo lwangaphakathi ukuba lunganwenweli kumoya osingqongileyo.

Ifanele indawo ezinothuli apho uthuli lunokuvutha kwaye lubangele ukuqhuma.

I-Exia (Ikhuselekile Ngaphakathi):

Usebenzisa iisekethe zamandla aphantsi ezingakwaziyo ukuvelisa iintlantsi okanye ubushushu obaneleyo ukuvutha umxube werhasi ongqongileyo.

Iyakwazi ukusebenza kwiatmosphere yerhasi eqhumayo ngaphandle kwesidingo sendawo evalekileyo enogqabhuko-dubulo.

I-Exib (uKhuseleko oloNgeziweyo):

Idibanisa izinto zoyilo lwe-Exd kunye ne-Exia, ibonelela ngamanyathelo okhuseleko aphuculweyo.

Iquka iindawo ezivaliweyo ezikhusela ugqabhuko-dubulo kunye neempawu ezongezelelweyo zokhuseleko njengeendawo ezivalelekileyo ezikhethekileyo, iibhokisi zesiphambuka, kunye neentambo.

Ukukhethwa kunye noLondolozo lweeHoists zoBungqina obuqhambukayo

Ukukhetha i-Hoist Right:

Qwalasela imeko-bume ethile enobungozi kunye neemfuno zomlinganiselo wobungqina bokudubula.

Qhagamshelana nemigangatho yokhuseleko efanelekileyo kunye nemimiselo (umz., IECEx, ATEX).

Funa isikhokelo kwiingcali ezivunyiweyo kunye nabavelisi.

Ugcino olululo:

Rhoqo jonga amacandelo angenabungqina bokudubula kumonakalo okanye ukuguqulwa.

Landela imiyalelo yomenzi wogcino kunye neenkqubo zokulungisa.

Qinisekisa ukuba zonke iinxalenye zitshintshwa okanye zilungiswe ngeendawo ezingqiniweyo ezinokumelana nokudubula.

Gcina amaxwebhu afanelekileyo ohlolo kunye nemisebenzi yokulondoloza.

Ngokukhetha ngononophelo ii-hoists-proof hoists ezinezixhobo ezifanelekileyo kunye noyilo, ukuthobela imigangatho yokhuseleko, kunye nokuphumeza iindlela ezifanelekileyo zokulondoloza, abaqhubi banokunciphisa umngcipheko wokuqhuma kunye nokuqinisekisa ukusebenza ngokukhuselekileyo kwezi ziqwenga zezixhobo ezibalulekileyo kwiindawo ezinobungozi.

Ukukhetha ihoist efanelekileyo ekhusela ugqabhuko-dubulo kubalulekile ekuqinisekiseni ukhuseleko kunye nokuthotyelwa kweendawo ezinobungozi. Nasi isikhokelo esibanzi sokukunceda wenze ukhetho olunolwazi:

1. Chonga iNdawo eSingqongileyo eyiNgozi:

Qinisekisa uhlobo lweegesi ezinobungozi okanye umphunga okhoyo kwindawo yokusebenza.

Hlela indawo enobungozi ngokusekwe kwiqela lerhasi kunye neklasi yogqabhuko-dubulo (umzekelo, iQela IIA, T3).

2. Qwalasela ukuKhawulwa koBungqina bokuQhamuka:

Khetha isinyusi esinomlinganiselo wokuthintela ugqabhuko-dubulo ohlangabezana okanye ogqitha iimfuno zommandla onobungozi.

Iireyithingi eziqhelekileyo ziquka i-Exd (i-flameproof), i-Exia (ikhuselekile ngaphakathi), kunye ne-Exib (ukhuseleko olongeziweyo).

3. Vavanya iSakhono soMthwalo kunye noBuphakamo bokuPhakamisa:

Qinisekisa umthamo omkhulu womthwalo ofunekayo kwimisebenzi yakho yokuphakamisa.

Qinisekisa ukuba umphakamo we-hoist wanele kwisicelo sakho.

4. Khetha uhlobo lweNqaku eLungileyo:

Qwalasela imiba efana nomthombo wamandla (umbane, amandla omoya, okwenziwa ngesandla), isimbo sokuxhoma (esisisigxina, esiphathekayo), kunye nomjikelo womsebenzi (rhoqo, ngamaxesha athile).

5. Qinisekisa ukuhambelana kwezinto:

Qinisekisa ukuba izixhobo zokuxhoma ziyahambelana nendawo enobungozi kunye neekhemikhali ezikhoyo.

Izinto eziqhelekileyo ziquka ubhedu lwe-aluminium, i-beryllium bronze, insimbi engenasici.

6. Qwalasela iziQinisekiso zoKhuseleko:

Qinisekisa ukuba i-hoist iqinisekisiwe yilabhoratri yovavanyo eyaziwayo, efana ne-IECEx okanye i-ATEX.

Qinisekisa ukuba isiqinisekiso sigubungela indawo ethile enobungozi kunye nesicelo.

7. Dibana noMvelisi kunye neeNgcali:

Funa isikhokelo kumenzi we-hoist kunye neengcali eziqeqeshiweyo kwiingcebiso ezithile.

Qwalasela imiba efana nokufakela, ulungiso, kunye nokufumaneka kweendawo ezisecaleni.

Iingcebiso ezongezelelweyo:

Beka phambili ii-hoists ezinolwakhiwo olomeleleyo kunye nerekhodi eqinisekisiweyo kwindawo enobungozi.

Khetha iihoists ezineempawu ezomeleza ukhuseleko, ezinjengokhuseleko lomthwalo omninzi, iindlela zokumisa kaxakeka.

Qwalasela ixabiso lilonke lobunini, kubandakanywa ixabiso lokuthenga okokuqala, iindleko zokulondoloza, kunye nexesha elinokubakho.

Khumbula, ukhuseleko kufuneka lube yeyona nto iphambili xa ukhetha izixhobo ezikhusela uqhushumbo. Ngokuphonononga ngononophelo izinto ezikhankanywe ngasentla kunye nokubonisana neengcali, unokwenza isigqibo esinolwazi esiqinisekisa ukusebenza okukhuselekileyo nokusebenzayo kwezi ziqwenga zibalulekileyo zezixhobo kwiindawo ezinobungozi.
