Ukukhethwa kunye neeMfuno zeSixhobo sokuqhunyiswa kweSandblasting kwi-Offshore Oil Production Platforms

一. IiMfuno zokuKhetha izixhobo

1. Ugqabhuko-bubungqina boYilo

Kunyanzelekile ukuba izixhobo zibambelele kuqhushumbo lwamazwe ngamazwe - imigangatho yobungqina efana ne-ATEX okanye i-IECEx. Amalungu ombane, kubandakanywa iinjini kunye neenkqubo zokulawula, kufuneka zibe nezatifikethi zokudubula (umzekelo, Ex d, Ex e). Oku kubalulekile ukuze kuthintelwe ukuvutha kweegesi ezinokutsha, ngaloo ndlela kuthintelwa ukudubula okunokuba yintlekele.

2. I-Corrosion - i-Resistant Materials

Umzimba oyintloko wesixhobo ukhethwa ukuba wakhiwe kwi-316L yensimbi engenasici okanye eshushu - dip galvanized steel. Kwimibhobho ye-sandblasting, kufuneka ibonise ukuxhathisa ukunxiba kunye netyuwa - ukumelana nenkungu. Ngokomzekelo, i-hoses ene-polyurethane lining kunye nokuqiniswa kwensimbi yensimbi zikhetho ezifanelekileyo.

3. Ukuguquguquka kokusingqongileyo

Isixhobo kufuneka sikwazi ukumelana nemekobume erhabaxa yaselwandle ephawulwa kukufuma okuphezulu, isitshizi setyuwa, kunye nokwahluka okubalulekileyo kobushushu. Kuyafuneka ukuba ube nenqanaba lokhuseleko ubuncinane le-IP65. Ukongeza, kufuneka iyilelwe ukunyamezela amandla omoya kunye namaza, iqinisekisa ukusebenza okuzinzileyo nokuba iqonga lifumana i-oscillations.

4. Ukuzenzekela kunye noLawulo olukude

Iinkqubo zokuqhunyiswa kwesanti ezizenzekelayo, ezinje ngengalo zerobhothi zokuqhunyiswa kwesanti, ziyacetyiswa kakhulu. Ezi nkqubo zinokucutha ungenelelo olwenziwa ngesandla kwaye zandise impumelelo yokusebenza. Ngaphezu koko, kufuneka zidityaniswe kunye neenzwa zokuhlola iiparamitha ezinjengoxinzelelo kunye nesantya sokuhamba kwe-abrasive ngexesha langempela.

二.UKhetho lweZixhobo ezingundoqo – Iindidi zoomatshini bokuqhunyiswa kwesanti

1. Uxinzelelo - ukondla oomatshini beSandblasting

Ukusebenza kuxinzelelo oluphezulu oluvela kwi-0.7 - 1.4 MPa, uxinzelelo - oomatshini be-sandblasting abondliwe basebenza kakuhle kwaye bafaneleke ngokukodwa kwimisebenzi emikhulu. Nangona kunjalo, zifuna ukusetyenziswa kwe-compressor yomoya enkulu ukuze isebenze ngokufanelekileyo.

2. Oomatshini bokuBuyisa iSandblasting

Kubandakanya inkqubo evaliweyo, i-vacuum recovery-sandblasting machines iyasebenza ekunciphiseni inkunkuma ene-abrasive kunye nokungcoliseka kwendalo. Oku kubenza babe lolona khetho lufanelekileyo kwimisebenzi kwiindawo ezithintelweyo eqongeni.

三. UkuKhethwa kweAbrasive

1. I-Metal Abrasives

I-Metal abrasives, njenge-steel grit (G25 - G40) kunye ne-steel shot, iphinda isetyenziswe kwaye ifaneleke kakuhle kwizicelo ezifuna unyango oluphezulu-ubunzulu bomgangatho.

2. I-non-metallic Abrasives

I-non-metallic abrasives, kuquka i-garnet kunye ne-aluminium oxide, ayifaki ingozi yokuvelisa i-spark. Nangona kunjalo, ubunzima bokubuyiswa kwe-abrasive kufuneka kuthathelwe ingqalelo xa usebenzisa ezi zixhobo.

四.Izixhobo ezixhasayo

1. IiCompressors zoMoya

I-oyile – iicompressor zomoya ezijijwayo simahla ziyacetyiswa, kunye nomthamo wonikezelo womoya omncinci oyi-6 m³/min. Umthamo wokwenene unokwahluka ngokuxhomekeke kwinani lemipu yokutshiza esetyenziswayo.

2. Iinkqubo zokususa uthuli

Ukuqhuma - abaqokeleli bothuli bobungqina, njengabo banebhegi - ukucwangciswa kohlobo kunye nokucoca i-HEPA, kubalulekile. Ezi nkqubo kufuneka zihambelane nemigangatho ye-OSHA yothuli ukuqinisekisa indawo yokusebenza ekhuselekileyo necocekileyo.

五. Ukhuseleko kunye nokuKhuselwa kokusiNgqongileyo

1. Amanyathelo oKhuseleko

Ukuthintela umbane ongatshintshiyo - iingozi ezinxulumene nazo, izixhobo kufuneka zibekwe ngokufanelekileyo. Izixhobo zegesi (zokubeka iliso kwi-LEL) kufuneka zifakwe kwindawo ye-sandblasting. Ukongezelela, bonke abasebenzi abasebenzayo kufuneka banxibe izixhobo zokuphefumula ezibonelelwa ngomoya (SCBA) kunye ne-anti-slip, i-anti - static iimpahla zokukhusela ukhuseleko lwabo.

2. IiMfuno zoKhuseleko lokusiNgqongileyo

Izinga lokubuyisela i-abrasive kufuneka libe ubuncinane ubuncinane be-90%. Inkunkuma kufuneka ilahlwe ngokuhambelana neKhowudi ye-IMDG. Ngokumalunga namanzi amdaka, kufuneka enziwe intlenge kwaye ahluzwe phambi kokuba akhutshelwe ukuthintela naziphi na iimpembelelo ezimbi kwisixokelelwano solwandle.

Ukuqukumbela, kwiplatifti ye-offshore isixhobo sokuqhunyiswa kwesanti, ukhuseleko kunye nokudubula - iimpawu zobungqina zibaluleke kakhulu. Ngexesha elifanayo, ukusebenza kakuhle kunye nokukhuselwa kwendalo akufuneki kuhoywe. Kucetyiswa ukuba ukhethe nayiphi na ingcinezelo - ezondliwe okanye iinkqubo zokubuyisela ngokusekelwe kwiimfuno ezithile zomsebenzi, kubandakanywa nobukhulu bendawo yokusebenza, ukucaciswa kweengubo, kunye neemeko zeqonga. Ukugcinwa rhoqo kunye noqeqesho lwabaqhubi lukwabalulekile ukuqinisekisa ukusebenza okuthembekileyo kwexesha elide kwezixhobo.

Ngolwazi oluthe kratya, nceda uzive ukhululekile ukuxoxa nenkampani yethu!
