Hupenyu hurefu hwebasa rekutonhodza
Zvakaoma kutenda, asi 34 muzana chete. simba rinowanikwa kubva mukupisa kwemafuta-mhepo musanganiswa rinoshandurwa kuva simba rinobatsira, kureva simba remagetsi. Iyi nhamba inoratidza, kune rumwe rutivi, kuti yakaderera sei kushanda kweavhareji injini yemotokari, uye kune rumwe rutivi, ingani simba rinoshandiswa pakugadzira kupisa. Iyo yekupedzisira inofanira kukurumidza kuparadzirwa kuitira kudzivirira kuwandisa uye nekudaro jamming injini.
Glycol mvura
Kuti utonhorese kwakaringana injini yemotokari, zvinodikanwa kushandisa chinhu chinogona kunyatso tora uye wobva wabvisa hombe yakawandisa yekupisa simba kunze. Iyo haigone kuve, semuenzaniso, mvura, nekuti nekuda kwehunhu hwayo (inotonhora pa 0 degrees C uye inovira pa100 degrees C), inobvisa zvisina kunaka kupisa kubva muhurongwa. Naizvozvo, masisitimu ekutonhora kwemotokari anoshandisa 50/50 musanganiswa wemvura uye monoethylene glycol. Musanganiswa wakadaro unoratidzwa nechando che -37 degrees C uye nzvimbo yekubikira ye108 degrees C. Chikanganiso chinowanzoitika ndechokushandisa imwe glycol. Sei? Zvinoitika kuti ipapo mikana yekubvisa kupisa kunobudirira kunoderedzwa, kunze kwekuti, undiluted glycol inotonhora pakushisa kwe-13 degrees C. Nokudaro, kushandiswa kweglycol yakachena kunogona kuita kuti injini iwedzere, iyo inogona kutotungamirira kubatwa. . Kuti uwane mhedzisiro yakanaka, sanganisa glycol nemvura yakasvibiswa muchiyero che1: 1.
Ne corrosion inhibitors
Nyanzvi dzinoteerera kuchena kwezvinhu zvinoshandiswa kutonhora injini. Chokutanga pane zvose, tiri kutaura pamusoro pekuchena kweglycol. Kushandiswa kwekupedzisira kwehutano hwakaderera kunobatsira pakuumbwa kwefoci yekuora muhutano hwekutonhora (nekuda kwekuumbwa kwemashizha ane acidic). Chinhu chinonyanya kukosha muhutano hweglycol ndiko kuvapo kwezvinonzi corrosion inhibitors. Basa ravo guru nderekuchengetedza inotonhorera system kubva kune zvese corrosion uye kuumbwa kwemadhipoziti ane njodzi. Corrosion inhibitors zvakare inodzivirira inotonhorera kubva mukuchembera nguva isati yakwana. Kangani iyo inotonhorera mumotokari marayaitha inofanira kuchinjwa? Izvo zvese zvinoenderana nemugadziri uye zvinowedzera zvinoshandiswa mazviri - zvekare kana organic.
Makore maviri kusvika matanhatu
Iwo akareruka anotonhorera ane ekare ekuwedzera akadai silicates, phosphates kana borates. Kukanganisa kwavo ndiko kukurumidza kupera kwezvinhu zvekudzivirira uye kuumbwa kwemari muhurongwa. Nokuda kwemvura iyi, zvinokurudzirwa kuchinja kunyange makore maviri ose. Mamiriro acho akasiyana nemvura ine organic compounds (inonzi inonzi carboxylic compounds), inozivikanwawo semvura yehupenyu hurefu. Chiito chavo chinobva pane catalytic effect. Mishonga iyi haibatike nesimbi, asi inongoiyananisa chete. Nekuda kweizvi, vanogona kuchengetedza zvirinani hurongwa kubva pakuumbwa kwenzvimbo dzekuora. Panyaya yezvinwiwa zvine hupenyu hurefu hwebasa, hupenyu hwavo hwesevhisi hunotsanangurwa semakore matanhatu, kana nezve 250 zviuru. km yekumhanya.
Kudzivirirwa uye kusarerekera
Iwo akanakisa anotonhorera ane organic kabhoni makomisheni haango chengetedza sisitimu kubva panjodzi yekuora, asi zvakare kudzivirira kuumbwa kwemadhipoziti ane njodzi anovhiringa maitiro ekutonhora. Izvi zvinwiwa zvakare zvinonyatso kudzikamisa acidic exhaust magasi anogona kupinda mumhepo yekutonhora kubva mukamuri yekupisa. Panguva imwecheteyo, iyo inokoshawo, haiiti nemapurasitiki uye elastomers anoshandiswa mumagadzirirwo ekutonhora emotokari dzemazuva ano. Zvinwiwa zvine organic additives zviri nani kudzivirira njodzi yekupisa injini kupfuura mamwe emaminerari, uye saka ivo vari kuwedzera kutsiva iyo yekupedzisira.
