Xa ukutshiswa komatshini wokuxuba i-asphalt akwanelanga, ukusetyenziswa kwepetroli kunye ne-diesel kunyuswa, okubangela ukunyuka kweendleko zemveliso; i-oyile ye-fuel eseleyo idla ngokulimaza izinto ezigqityiweyo, okubangela ukuhlawulwa kwezinto ezigqityiweyo; xa ukutshisa kunganelanga, Igesi yokukhupha iqulethe umsi we-welding. Xa umsi we-welding udibana nebhegi yokuqokelela uthuli kwisixhobo sokususa uthuli, iya kuncamathela kumphezulu ongaphandle wengxowa yothuli, ibangele umonakalo kwingxowa yothuli, ibangele ukuba idrafti yedrafti yedrafti ivalwe kwaye ingabikho ngokwaneleyo. ekugqibeleni kukhokelela kwi-hemiplegia. Isixhobo asinakwenziwa.
Ukuba inokugcinwa ngokufanelekileyo, inokugcina imali eninzi kwaye yandise ubomi benkonzo yenkqubo yokutshisa. Ngoko ke, siyintoni isizathu sokungavuthi ngokwaneleyo? Indlela yokusombulula ngayo?

Umgangatho wamafutha
Iioyile ezisetyenziswa ngokuqhelekileyo kunye nezibaso zoomatshini bokuxuba ikhonkrithi ye-asphalt zidityaniswe ngabathengisi beoyile ababonelelweyo kusetyenziswa i-oyile ye-oyile eqhelekileyo kunye nokuxhasa ukutsha kunye nezinye izithinteli. Izithako zinzima kakhulu. Ngokusekelwe kumava okusetyenziswa kwendawo, i-oyile ye-fuel inokuqinisekisa ukuba i-burner isebenza ngokuqhelekileyo kwaye ivutha ngokupheleleyo ngokudibana nale parameters ilandelayo: ixabiso le-calorific alikho ngaphantsi kwe-9600kcal / / kg; i-kinematic viscosity kwi-50 ° C ayikho ngaphezu kwe-180 cst; umxholo wentsalela yoomatshini awukho ngaphezu kwe-0.3%; isiqulatho sokufuma asidluli kwi-3%.
Phakathi kweeparamitha ezine ezingentla, ipharamitha yexabiso le-calorific yimeko efunekayo yokuqinisekisa ukuba umtshisi unokubonelela ngexabiso le-calorific. I-viscosity ye-kinematic, i-residu yomatshini kunye neeparitha zomswakama womswakama zichaphazela ngokuthe ngqo ukufana komlilo; kinematic viscosity, mechanical Ukuba ukubunjwa kunye nokufuma kwentsalela yesixhobo kudlula umgangatho, i-atomization ye-oyile ye-fuel kwi-nozzle yesitshisi iya kuba mbi, umsi we-welding awunakuxutywa ngokupheleleyo negesi, kwaye ukutshisa okungakhethiyo akunakuba mbi. iqinisekisiwe.
Ukuqinisekisa ukutsha okungenamkhethe, ezi parameters ezibalulekileyo zingentla kufuneka zidibene xa ukhetha ioli ye-fuel.

Isitshisi
Impembelelo ye-atomization kwi-ignition stability
I-oyile yepetroli ekhanyayo itshizwe njengenkungu ngokusebenzisa i-atomizing nozzle yompu weoyile phantsi koxinzelelo lwempompo yepetroli okanye ukusebenzisana phakathi koxinzelelo lwepompo yepetroli kunye negesi ephezulu yoxinzelelo. Ubungakanani be-welding fume particles buxhomekeke kwi-atomization effect. Umphumo wokutshisa umbi, iinqununu zenkungu zikhulu, kwaye indawo yokudibanisa yokudibanisa negesi incinci, ngoko ukufana komlilo kubi.
Ukongeza kwi-kinematic viscosity ye-oyile ye-fuel light ekhankanywe ngaphambili, kukho kwakhona izinto ezintathu ezichaphazela i-atomization ye-atomization yeoli yokukhanya evela kwi-burner ngokwayo: ukungcola kunamathele kwi-gun nozzle okanye konakaliswe kakhulu; ipompo yepetroli Umonakalo omkhulu okanye ukungaphumeleli kwesixhobo se-transformer kubangela ukuba uxinzelelo lwe-steam lube ngaphantsi koxinzelelo lwe-atomization; Uxinzelelo lwegesi ephezulu yoxinzelelo olusetyenziselwa i-atomization iphantsi kunoxinzelelo lwe-atomization.
Izisombululo ezihambelanayo zezi: hlamba umbhobho ukususa ukungcola okanye ukubuyisela umbhobho; buyisela ipompo yepetroli okanye ucime impazamo ye-transformer; lungisa uxinzelelo loxinzelelo lomoya kwixabiso eliqhelekileyo.

Igubu elomileyo
Ukutshatiswa kobume bedangatye lokutshisa kunye nesakhiwo somkhusane wezinto kwi-drum eyomileyo kunempembelelo enkulu ekufaneni komlilo. Ilangatye lomlilo lomlilo lifuna indawo ethile. Ukuba kukho ezinye izinto ezihlala kwesi sithuba, ngokuqinisekileyo kuya kuchaphazela isizukulwana esiqhelekileyo somlilo. Njengendawo yokutshisa igubu elomileyo, ibonelela ngesithuba sokutshisa okuqhelekileyo ukuvelisa amadangatye. Ukuba kukho ikhethini kule ndawo, izinto eziwa ngokuqhubekayo ziya kuthintela ilangatye kwaye zitshabalalise ukufana komlilo.
Kukho iindlela ezimbini zokusombulula le ngxaki: enye kukutshintsha imilo yedangatye ngokutshintsha i-angle ye-atomization ye-nozzle yesitshisi okanye ukulungelelanisa i-valve yesibini yokungenisa umoya elawula ukumila kwedangatye, ukuze idangatye litshintshe ukusuka kwixesha elide kwaye lincinci. mfutshane kunye nobunzima; enye kukutshintsha umkhusane wezinto ezibonakalayo kwindawo yokutshisa igubu elomileyo ngokutshintsha ulwakhiwo lwencakuba yokuphakamisa izinto ukulungelelanisa umkhusane wezinto ezikule ndawo ukusuka kwishinyene ukuya kwindawo encinci okanye akukho mkhusane wezinto eziphathekayo ukunika indawo eyaneleyo yomlilo wokutshisa.

Idrafti yezixhobo zokususa uthuli lwefeni
Ukumataniswa kwedrafti yedrafti yokususa uthuli lwefeni isixhobo kunye nesitshisi sikwanefuthe elikhulu kwiyunifomu yomlilo. Idrafti yedrafti yezixhobo zokususwa kothuli lwe-asphalt yekhonkrithi yekhonkrithi yenzelwe ukuba ifunxe ngokukhawuleza igesi yokukhupha eyenziwa ngumlilo emva kokutshisa, kwaye inike indawo ethile yokutshisa okulandelayo. Ukuba umbhobho kunye nezixhobo zokususa uthuli lwedrafti yesixhobo sokususa uthuli lwefeni zivaliwe okanye umbhobho ufakwe umoya, irhasi yokuphuma kwisitshisi iya kuthintelwa okanye ingonelanga, kwaye irhasi yokuphuma iya kuqhubeka iqokelelana kwindawo yokutshisa ?? igubu elomileyo, elihlala kwindawo yokutshisa kwaye libangele ukuntumeka okunganeleyo.
Indlela yokusombulula le ngxaki yile: vula umbhobho wefeni oyilwayo ovaliweyo okanye isixhobo sokususa uthuli ukuqinisekisa ukuhamba kakuhle kwefeni eyidrafti. Ukuba umbhobho ufakwe umoya, indawo yokungena umoya kufuneka ifakwe.
