Kuedzwa kweDINSEN kweacid-base bvunzopombi yesimbi yakakandwa(inonziwo SML pipe) inowanzoshandiswa kuongorora kuramba kwayo ngura, kunyanya munzvimbo dzine acidic nealkaline. Mapaipi emvura anoshandiswa zvakanyanya mumichina yemvura, drainage uye maindasitiri nekuda kwehunhu hwayo hwakanaka hwemakanika uye kuramba ngura. Aya ndiwo matanho akajairika uye matanho ekudzivirira pakuita bvunzo dzeacid-base pamapaipi eSML:
Chinangwa chekuedza uku
Ongorora kuramba kwesimbi inopinza mu ductile iron munzvimbo dzine acidic nealkaline.
Sarudza kugadzikana kwayo kwemakemikari pasi pemamiriro akasiyana epH.
Ipa ruzivo rwekusarudza zvinhu mukushandisa kwazviri.
Zvinhu zvekuedza
Mienzaniso yemapaipi esimbi yakakandwa (yakachekwa kuita saizi dzakakodzera).
Mhinduro dzine asidhi (dzakadai se sulfuric acid inonyungudika, hydrochloric acid inonyungudika, pH inogona kugadziriswa sezvinodiwa).
Mhinduro dzealkaline (dzakadai se sodium hydroxide solution, pH value inogona kugadziriswa sezvinodiwa).
Magaba (magaba egirazi kana epurasitiki asingapindi acid).
Zvishandiso zvekuyera (pH meter, electronic balance, vernier caliper, nezvimwewo).
Midziyo yekuyera mwero wengura (yakadai seovheni yekuomesa uye chiyero chinodiwa pakuderedza uremu).
Midziyo yekudzivirira (magurovhosi, magogorosi, majasi ekurabhoritari, nezvimwewo).
Matanho ekuyedza
Kugadzirira muenzaniso:
Cheka pombi yeSML wobva waona kuti pamusoro payo pakachena uye hapana mafuta.
Chiyera uye nyora saizi yekutanga nehuremu hwemuenzaniso.
Gadzirira mhinduro:
Gadzirira mhinduro ine acidic uye alkaline ye pH inodiwa.
Shandisa chiyereso chepH kuti uongorore pH yemushonga.
Kuedza kunyudza:
Nyikai DINSEN cast iron pipe sampuro mu acidic solution nemu alkaline solution zvakateerana.
Iva nechokwadi chekuti sampuro yanyikwa mumvura yese uye nyora nguva yekunyikwa mumvura (senge maawa makumi maviri nemana, mazuva manomwe, mazuva makumi matatu, nezvimwewo).
Kucherechedza uye kurekodha:
Tarisa shanduko dzepamusoro pemuenzaniso nguva nenguva (dzakadai sekuora, kuchinja kweruvara, kunaya kwemvura, nezvimwewo).
Nyora shanduko yeruvara rwemushonga uye kuumbwa kwemvura.
Bvisa muenzaniso:
Kana nguva yakatarwa yasvika, bvisai muenzaniso moisuka nemvura yakacheneswa.
Omesai sampuro moyera huremu hwayo nekuchinja kwehukuru hwayo.
Kuverenga kwehuwandu hwengura:
Mwero wekuora unoverengerwa uchishandisa nzira yekuderedza uremu, uye fomura yacho ndeiyi:Mwero wengura = nzvimbo yepamusoro × nguva
Kuderedza huremu:
Enzanisa mwero wekuora munzvimbo dzine acidic nealkaline.
Kuongorora mhedzisiro:
Ongorora kuramba kwesimbi inopinza mu ductile iron pasi pemamiriro akasiyana e pH.
Ongorora kushanda kwayo mumabasa anoshanda.
Zvekungwaririra
Dziviriro yekuchengetedzwa:
Mhinduro dzeasidhi nealkali dzinoparadza, uye vanoedza vanofanira kupfeka michina yekudzivirira.
Kuedza uku kunofanirwa kuitwa munzvimbo ine mhepo inofefetera zvakanaka.
Kuwanda kwemhinduro:
Sarudza huwandu hwakakodzera hweasidhi nealkali zvichienderana nemamiriro chaiwo ekushandiswa.
Kugadziriswa kwemuenzaniso:
Iva nechokwadi chekuti pamusoro pemuenzaniso pakachena kudzivirira kusvibiswa kunokanganisa mhedzisiro yekuedza.
Nguva yekuyedza:
Isa nguva yakakodzera yekunyudza mvura zvichienderana nechinangwa chekuedza kuti unyatsoongorora mashandiro engura.
Mhedzisiro yekuedza uye mashandisirwo
Kana pombi yesimbi ine ductile ikaita ngura yakaderera munzvimbo ine acid-base, zvinoreva kuti ine ngura yakanaka uye yakakodzera nzvimbo dzakaoma dzemakemikari.
Kana mwero wekuora wakakwira, matanho ekuwedzera ekudzivirira ngura (akadai sekuputira kana kudzivirira cathodic) anogona kudiwa.
Kuburikidza nekuyedza kweacid-base, kugadzikana kwemakemikari emapombi esimbi ane ductile kunogona kunzwisiswa zvizere, zvichipa hwaro hwesainzi hwekushandiswa kwawo munzvimbo dzakatarwa.
Nguva yekutumira: Kukadzi-28-2025
