Umbhobho odityanisiweyo we-Spiral (SSAW) ukususwa komhlwa kunye nenkqubo yokunqanda ukubola: Ukususwa komhlwa yinxalenye ebalulekileyo yenkqubo yombhobho yokunqanda ukudumba. Okwangoku, kukho iindlela ezininzi zokususa umhlwa, ezifana nokususwa kwe-rust manual, ukuqhuma kwesanti kunye nokususwa kwe-rust pickling, njl. iindlela zokususa.

1. Ukunciphisa ngesandla

Susa isikali kunye nokugalela isanti kumphezulu imibhobho, izixhobo kunye nezikhongozeli kunye scraper kunye nefayile, uze usebenzise ibrashi yocingo ukususa umhlwa edadayo phezu komphezulu imibhobho, izixhobo kunye nezikhongozeli, uze uzigube nge sandpaper, kwaye ekugqibeleni uzisule. nabo ngesilika yomqhaphu. umnatha.

2. Ukususwa komhlwa koomatshini

Okokuqala sebenzisa i-scraper okanye ifayile ukususa isikali kunye nokuphosa isanti phezu kombhobho; ke umntu omnye uphambi komatshini wokuhla kwaye omnye usemva komatshini wokuhla, kwaye umbhobho uhlanjululwe ngokuphindaphindiweyo kumatshini wokuhlamba kuze kube yilapho umbala wokwenene wentsimbi ubonakaliswe; Ngaphambi kokuthambisa, yisule kwakhona ngesilika yomqhaphu ukususa uthuthu oludadayo kumphezulu.

3. I-oyile yebrashi ye-Anti-corrosion

Imibhobho, izixhobo kunye ne-container valves zi-anti-corrosion kwaye zifakwe i-oyile ngokweemfuno zoyilo. Xa kungekho mfuneko yoyilo, le migaqo ilandelayo kufuneka ilandelwe:

a. Imibhobho egxunyekwe phezulu, izixhobo kunye nezikhongozeli kufuneka ziqatywe ngepeyinti enye yepeyinti enqanda umhlwa, emva koko iidyasi ezimbini zeedyasi eziphezulu kufuneka zipeyintwe phambi kokuba zinikezelwe. Ukuba kukho iimfuno zokugcinwa kobushushu kunye ne-anti-condensation, iingubo ezimbini zepeyinti ye-anti-rust kufuneka zidwetshwe;

b. Peyinta iidyasi ezimbini zepeyinti echasene nomhlwa kwimibhobho efihliweyo, izixhobo kunye nezikhongozeli. Ingubo yesibini yepeyinti ye-anti-rust kufuneka ipeyinti emva kokuba isambatho sokuqala somile ngokupheleleyo, kwaye ukuhambelana kwepeyinti ye-anti-rust kufuneka ifaneleke;

3. Xa umbhobho ongcwatyiweyo usetyenziswa njengomaleko wokunqanda ukudumba, ukuba wakhiwe ebusika, kuyacetyiswa ukuba kusetyenziswe ioli yokunyibilikisa zerabha okanye i-aviation petroleum ukunyibilikisa i-asphalt yepetroleum eyi-30 A okanye 30 B. Iintlobo ezimbini:

① Ukubrasha ngesandla: Ibrashi yezandla kufuneka isetyenziswe kumaleko, kwaye umaleko ngamnye kufuneka uphindwe, unqamleze, kwaye i-coating kufuneka igcinwe ifanayo ngaphandle kokuphoswa okanye ukuwa;

② Ukutshiza ngoomatshini: Ukuhamba kwepeyinti etshiziweyo kufuneka kube ngokuthe ngqo kwindawo epeyintiweyo ngexesha lokutshiza. Xa indawo epeyintiweyo isicaba, umgama phakathi kombhobho kunye nomphezulu opeyintiweyo kufuneka ube yi-250-350mm. Ukuba umphezulu wepeyintiwe ngumphezulu we-arc, umgama phakathi komlomo kunye nomgangatho opeyintiweyo kufuneka ube malunga ne-400mm. , Xa utshiza, ukuhamba kwe-nozzle kufuneka kube yinto efanayo, isantya kufuneka sigcinwe kwi-10-18m / min, kunye noxinzelelo lomoya oxinyiweyo osetyenziselwa ukutshiza ipeyinti kufuneka ube ngu-0.2-0.4MPa.
