Kuvandudza Zvivakwa zveMarara Uchishandisa Mapaipi eSpiral Submerged Arc (SSAW) Mufananidzo Unoratidzwa

Tsananguro pfupi:

Chikamu chino cheEuropean Standard chinotsanangura mamiriro ekugadzirwa kwezvinhu zvekuvaka zvakagadzirwa nesimbi dzakasungirirwa, dzine maburi edenderedzwa, sikweya kana rectangular uye chinoshanda kuzvikamu zvekuvaka zvisina maburi zvakagadzirwa nesimbi dzinotonhora pasina kurapwa kwekupisa kunotevera.

Pfupiso yepombi yakasungirirwa ye spiral submerged arc:

Pombi yesimbi yakadzika pasi pearc, inozivikanwa se spiral submerged arc welded pipe, inoumbwa nekukungurutsa simbi inopisa yakamonerwa kuita spiral shape uye kuibatanidza pamwe chete nemusono we weld uchishandisa nzira ye submerged arc welding. Mapaipi aya anopa mwero wepamusoro wekuoma, simba uye kuramba ngura, zvichiita kuti akwanise kushandiswa mumapurojekiti akakosha ezvivakwa zvakaita semasewer.

Mabhenefiti emapaipi eSSAW mukushandiswa kwetsvina:

1. Kugara kwenguva refu: Mapaipi akasungirirwa nesimbi yepamusoro-soro akagadzirwa nesimbi yepamusoro-soro uye anogara kwenguva refu. Ane simba rekutsungirira mitoro inorema uye mamiriro ekunze akaipisisa, zvichiita kuti mapaipi etsvina agare kwenguva refu.

2. Kuramba ngura: Maitiro ekupisa anowedzera dziviriro kune pombi yakasungirirwa yesimbi yakasungirirwa, zvichiita kuti isanyanya ngura. Hunhu uhwu hwakakosha kune masisitimu etsvina nekuti anowanzo sangana nemamiriro ekunze ane makemikari nehupenyu.

3. Dhizaini Inodzivirira Kudonha Kwemvura: Pombi yakasungirirwa ye spiral inonyudzwa ne arc inogadzirwa uchishandisa nzira yekubatanidza inoenderera mberi kuti ive nechokwadi chekuti chimiro hachibvi mvura. Chinhu ichi chinodzivirira mukana wekupinda kana kubuda kwemvura, nokudaro zvichideredza mukana wekusvibiswa kwevhu uye kudiwa kwekugadzirisa kunodhura.

4. Kuchinjika uye kuchinjika: Pombi dzakasungirirwa dzakaita se spiral submited arc dzinogona kugadzirwa kuti dzikwane dhayamita dzakasiyana-siyana, kureba uye materu, zvichibvumira kuchinjika kukuru mukugadzirwa kwemasisitimu emasiponji. Dzinogona kuchinjika zviri nyore kuchinjika kune shanduko dzenzvimbo nekwakananga, zvichiita kuti mvura yakasviba ifambe zvakanaka kunyangwe muma network emasiponji akaomarara.

5. Kushanda Nemutengo Wakaderera: Kana tichienzanisa nezvinhu zvechinyakare zvemapombi etsvina zvakaita sekongiri kana ivhu, mapombi akasungirirwa esimbi arc anogona kuchengetedza mari yakawanda pakuaisa nekugadzirisa. Kureruka kwawo kunoderedza mari yekutumira uye ari nyore kuisa, zvichideredza zvinodiwa nevashandi. Pamusoro pezvo, hupenyu hwawo hwekushanda kwenguva refu uye zvinodiwa zvishoma zvekugadzirisa zvinobatsira pakubudirira kwemari kwenguva refu.

a. Nzira yekubvisa oxidation inotsanangurwa seinotevera: FF: Simbi yakafa zvizere ine zvinhu zvinosunga nitrogen muhuwandu hwakakwana kuti isunge nitrogen iripo (semuenzaniso 0,020% yeAl yose kana 0,015% yeAl inonyungudika). b. Kukosha kwakanyanya kwenitrogen hakushandi kana makemikari ari muchikamu ichi achiratidza huwandu hweAl hushoma hwe0,020% nechiyero cheAl/N che2:1, kana kana paine zvimwe zvinhu zveN-binding zvakakwana. Zvinhu zveN-binding zvinofanira kunyorwa muGwaro reKuongorora.

Mashandisirwo emapombi eSSAW mumasisitimu etsvina:

1. Mambure eManispa: Mapaipi eSSAW anowanzo shandiswa mukuvaka migero mikuru yetsvina inoshandira nzvimbo dzekugara, dzekutengeserana nedzemaindasitiri. Simba rawo uye kuramba ngura kunoita kuti ave sarudzo yakanaka yekutakura mvura yakasviba munzvimbo refu.

2. Kuyerera kwemvura inonaya:Mapaipi eSSAWZvinogona kudzora mvura inoyerera zvakanaka uye kudzivirira mafashamo mumaguta. Kusimba kwawo kunobvumira kutamiswa kwemvura yakawanda zvakanaka kana mvura yakwira.

3. Chigadziko chekuchenesa tsvina: Mapaipi akasungirirwa arc arc anogona kushandiswa mukuvaka zvikamu zvakasiyana-siyana zvechigadziko chekuchenesa tsvina, kusanganisira mapaipi etsvina asina kucheneswa, matangi emhepo uye masisitimu ekuchenesa tsvina. Kusagona kwavo kuuraya makemikari anoparadza uye kugona kwavo kubata kumanikidzwa kwakasiyana-siyana kunoita kuti vashande munzvimbo dzakaoma kudaro.

Mukupedzisa:

Kusarudza pombi dzakakodzera kwakakosha pakuvaka nekugadzirisa masisitimu ako etsvina. Mapaipi eSpiral submerged arc (SSAW) aratidza kuva mhinduro inodhura, inogara kwenguva refu uye inoshanda zvakasiyana-siyana yezvivakwa zvetsvina. Nekudzivirira kwavo ngura, dhizaini yavo isingadonhedze mvura, uye kugona kuchinjika kunzvimbo dzakasiyana, mapaipi eSSAW anogona kutakura mvura yakasviba zvinobudirira, zvichibatsira mukukura kwemaguta. Kushandiswa kwemapaipi eSpiral submerged arc welded mumapurojekiti etsvina kunogona kugadzira nzira yekuvandudza network dzetsvina kuti dzisangane nezvinodiwa zviri kukura zvekuvandudzwa kwemaguta.
