Ukukhethwa kwemishini yokuqhuma isihlabathi yamapulatifomu okukhiqiza uwoyela ogwini kudinga ukucatshangelwa okubanzi kwezinto ezihlukile zemvelo, ukuphepha, ukusebenza kahle, kanye nokuqina. Nazi izici ezibalulekile:
一. Izidingo Zokukhetha Imishini
1. Umklamo wobufakazi bokuqhuma
Kubalulekile ukuthi imishini ilandele izindinganiso zomhlaba wonke zokuvikela ukuqhuma njenge-ATEX noma i-IECEx. Izingxenye zikagesi, okuhlanganisa ama-motor nezinhlelo zokulawula, kumele zibe nezitifiketi zokuvikela ukuqhuma (isb., Ex d, Ex e). Lokhu kubalulekile ukuvimbela ukushiswa kwamagesi avuthayo, ngaleyo ndlela kugwenywe ukuqhuma okungaba yinhlekelele.
2. Izinto Ezimelana Nokugqwala
Umzimba oyinhloko wemishini kungcono wakhiwe ngensimbi engagqwali engu-316L noma ngensimbi eshisayo egayiwe. Kumapayipi okuqhumisa isihlabathi, kufanele abonise ukumelana nokuguguleka kanye nokumelana nosawoti kanye nenkungu. Isibonelo, amapayipi ane-polyurethane lining kanye nokuqinisa ucingo lwensimbi kuyizinketho ezifanele.
3. Ukuzivumelanisa Nezimo Kwezemvelo
Imishini kufanele ikwazi ukumelana nemvelo yasolwandle enzima ebonakala ngomswakama ophezulu, ukufuthwa ngosawoti, kanye nokushintshashintsha okukhulu kwezinga lokushisa. Kudingeka ibe nezinga lokuvikela okungenani elingu-IP65. Ngaphezu kwalokho, kufanele iklanywe ukuze ikwazi ukumelana namandla omoya namagagasi, iqinisekise ukusebenza okuzinzile ngisho nalapho ipulatifomu ihlangabezana nokushukuma.
4. Ukuzenzakalela kanye nokulawula kude
Izinhlelo zokuqhumisa isihlabathi ezizenzakalelayo, njengezingalo zokuqhumisa isihlabathi ezingamarobhothi, ziyanconywa kakhulu. Lezi zinhlelo zinganciphisa ukungenelela ngesandla futhi zithuthukise ukusebenza kahle. Ngaphezu kwalokho, kufanele zihlanganiswe nezinzwa ukuze ziqaphe imingcele efana nokucindezela kanye nesivinini sokugeleza okukhulu ngesikhathi sangempela.
二. Ukukhethwa Kwemishini Eyinhloko – Izinhlobo Zemishini Yokuqhumisa Inhlabathi
1. Imishini Yokuqhumisa Isihlabathi Ecindezelwe
Njengoba isebenza ngokucindezela okuphezulu okusukela ku-0.7 - 1.4 MPa, imishini yokuqhuma kwesihlabathi enikwe ukucindezela isebenza kahle kakhulu futhi ifaneleka kakhulu emisebenzini emikhulu. Kodwa-ke, idinga ukusetshenziswa kwe-air compressor enamandla amakhulu ukuze isebenze kahle.
2. Imishini Yokuqhumisa Inhlabathi Yokubuyisa I-Vacuum
Njengoba inesistimu ye-closed – loop, imishini yokuhlanza isihlabathi yokuhlanza i-vacuum iyasebenza ekunciphiseni imfucuza ekhuhlayo kanye nokungcoliswa kwemvelo. Lokhu kuyenza ibe ukukhetha okuhle kakhulu kokusebenza ezindaweni ezivinjelwe epulatifomu.
三. Ukukhetha Okungahluzeki
1. Izithambisi Zensimbi
Izinto zokubhula zensimbi, njenge-grit yensimbi (G25 - G40) kanye ne-steel shot, zingasetshenziswa kabusha futhi zifaneleka kahle izinhlelo zokusebenza ezidinga ukwelashwa okuphezulu komhlaba.
2. Izithambisi ezingezona ezensimbi
Izinto zokuzisusa ezingezona ezensimbi, okuhlanganisa i-garnet ne-aluminium oxide, azibangeli ingozi yokukhiqizwa kwenhlansi. Noma kunjalo, ubunzima bokubuyiselwa kwezinto ezisusayo kufanele bucatshangelwe lapho kusetshenziswa lezi zinto.
Imishini Yokusekela
1. Ama-Air Compressor
Kunconywa ama-compressor omoya angenawo uwoyela nezikulufo, anomthamo womoya okungenani ongu-6 m³/min. Umthamo wangempela ungahluka kuye ngenani lezibhamu zokufutha ezisetshenziswayo.
2. Izinhlelo Zokususa Uthuli
Kubalulekile ukuqoqa uthuli olungenaziqhumane, njengalabo abanesikhwama kanye nokuhlunga i-HEPA. Lezi zinhlelo kufanele zihambisane nezindinganiso zothuli ze-OSHA ukuqinisekisa indawo yokusebenza ephephile nehlanzekile.
五. Ukuphepha Nokuvikelwa Kwemvelo
1. Izindlela Zokuphepha
Ukuze kuvinjelwe izingozi ezihlobene nogesi ongashintshi, imishini kufanele ifakwe kahle. Ama-gas detector (okuqapha i-LEL) kufanele afakwe endaweni yokuqhuma kwesihlabathi. Ngaphezu kwalokho, bonke abasebenzi abasebenzayo kudingeka bagqoke imishini yokuphefumula enikezwa umoya (i-SCBA) kanye nezingubo ezivimbela ukushelela, ezivimbela ukushibilika ukuze bavikele ukuphepha kwabo.
2. Izidingo Zokuvikela Imvelo
Izinga lokubuyisa imfucuza ebhulashile kufanele okungenani libe ngu-90%. Imfucuza ebhulashile kumele ilahlwe ngokuhambisana neKhodi ye-IMDG. Ngokuphathelene namanzi amdaka, kufanele afakwe futhi ahlungwe ngaphambi kokuba akhishwe ukuze kuvinjelwe noma yimuphi umthelela omubi ohlelweni lwemvelo lwasolwandle.
Ekuphetheni, ngemishini yokuqhuma kwesihlabathi epulatifomu yasogwini, ukuphepha kanye nokuqhuma - izici zobufakazi zibaluleke kakhulu. Ngesikhathi esifanayo, ukusebenza kahle kanye nokuvikelwa kwemvelo akufanele kunganakwa. Kunconywa ukukhetha noma yiziphi izinhlelo zokucindezela - eziphakelwayo noma zokubuyisa ngokusekelwe ezidingweni ezithile zomsebenzi, kufaka phakathi ubukhulu bendawo yokusebenza, imininingwane yokumboza, kanye nezimo zepulatifomu. Ukugcinwa njalo kanye nokuqeqeshwa komqhubi nakho kubalulekile ukuqinisekisa ukusebenza okuthembekile kwesikhathi eside kwemishini.
Ukuze uthole ulwazi olwengeziwe, sicela ukhululeke ukuxoxa nenkampani yethu!
