Yintoni ubushushu obufanelekileyo baManzi kwiPerkins Generator

Abanye abachwephesha bathanda ukunyenyisa ubushushu bamanzi ophumayo buphantsi kakhulu xa besebenzisa iseti yejenereyitha yedizili.Bakholelwa ukuba ukushisa kwamanzi kuphantsi, i-cavitation ayiyi kwenzeka kumpompo wamanzi, amanzi okupholisa (ulwelo) akayi kuphazamiseka, kwaye kukho ukhuseleko olusetyenziswayo.Enyanisweni, ukuba nje ukushisa kwamanzi akudluli i-95 ℃, i-cavitation ayiyi kwenzeka, kwaye amanzi okupholisa (ulwelo) akayi kuphazamiseka.

Ngokuchasene noko, ukuba ubushushu bamanzi buphantsi kakhulu, kuyingozi kakhulu ekusebenzeni kwe-injini ye-diesel.Ukuba iqondo lobushushu lamanzi liphantsi kakhulu, liya kuzisa ikakhulu ezi ngozi zilandelayo:

1.Isizathu kukuba iqondo lokushisa liphantsi, iimeko zokutsha kwedizili kwi-cylinder ziwohloka, ixesha lokutshisa landa emva kokuvutha, i-injini ilula ukusebenza nzima, yenza umonakalo we-crankshaft bearings, i-piston rings kunye nezinye iindawo, zinciphisa amandla. kunye noqoqosho.

I-2.Amanzi kunye negesi emva kokutsha kulula ukudibanisa eludongeni lwe-cylinder, okubangela ukubola kwesinyithi.

3.Yi-diesel eza kutsha enokuthi idibanise i-oyile ye-injini kwaye yonakalise ukuthambisa.

I-4.Kukutsha okungaphelelanga kwepetroli eyenza i-colloid, ukwenzela ukuba i-piston ring igxininiswe kwi-piston ring groove, i-valve ibambelele, kwaye uxinzelelo kwi-cylinder luyancipha ekupheleni koxinzelelo.

5.Kungenxa yokuba ubushushu bamanzi buphantsi kakhulu, i-oyile ye-oyile iphantsi, i-oyile iyancipha kwaye i-fluidity iba yimbi, okukhokelela ekuboneleleni kweoli eyaneleyo.Ukongeza, i-crankshaft ethwele imvume iba ncinci kwaye ukuthambisa kubi.

Umonakalo wobushushu bamanzi aphantsi awunakujongelwa phantsi.Ukushisa okuphantsi kakhulu kwamanzi okupholisa kuya kukhokelela kumxube werhasi yokutsha ngokwaneleyo, ukuncitshiswa kwamandla, ukubola kwesinyithi, ukuhlanjululwa kwe-oyile ye-injini, iimeko zokuthambisa ezisezantsi, i-injini erhabaxa, umonakalo owenziwe mandundu kwiibheringi ze-crankshaft, amakhonkco episton kunye nezinye izinto, ukunciphisa amandla kunye noqoqosho.Isenokubangela ukuba izinto ezikhutshwayo zigqithe imigangatho.Iimbangela zobushushu bamanzi e-injini ephantsi azintsonkothanga njengobushushu bamanzi obuphezulu.Ngokuqhelekileyo, i-thermostat yonakele okanye ifeni yokupholisa inempazamo.

Yintoni ubushushu bamanzi obufanelekileyo Perkins iiseti generator ?

Xa i-injini isebenza, ubushushu bamanzi okupholisa kwiseti yejenereyitha yedizili iya kugcinwa kuma-80 ukuya kuma-90 ℃, kwaye ke inokungena ukusebenza komthwalo opheleleyo, kungenjalo injini ayiyi kusebenza ngokuqhelekileyo.Ebusika, iqondo lobushushu le-ambient ye-diesel generator liphantsi, kwaye iqondo lokupholisa elihambelanayo nalo liphantsi.Ke ngoko, ijenereyitha yedizili kufuneka ifudunyezwe phambi kokuba iqale.Xa i-injini ye-diesel ikumandla ayo aphezulu asebenzayo, ubushushu bokupholisa kufuneka bube malunga ne-80 °.Xa usebenzisa i-diesel generator ebusika, kungcono ukuqinisekisa ukuba ukushisa kwamanzi malunga ne-80 ° xa ulungiselela ukuqhuba umthwalo.

Amaqondo obushushu ehlotyeni adla ngokuba phezulu, amanye afikelela kuma-44.5 ngokukaCelsius.Ngexesha elishushu ngolo hlobo, iqondo lobushushu lesipholisi liyenyuka ngokukhawuleza.Xa ubushushu bamanzi buyi-100 ℃ kwaye iqondo lobushushu liphezulu, i-injini ye-diesel inokubangela iingozi ze-cylinder.Ngoko ke, xa isisipholisi singaphezu kwama-95 ℃, ijenereyitha yedizili iyakuyeka ukusebenza okanye icuthe umthwalo.

Ubushushu bamanzi beseti yejenereyitha yedizili buphezulu kakhulu, ngenxa yokungonelanga kwesipholisi, umbhobho wamanzi ovalekileyo, ukusilela kwethermostat, ukusilela kwempompo yamanzi kunye nokusilela kweclutch yefeni.Ukuba ubushushu be-injini ye-diesel yesethi ye-generator iphezulu kakhulu, ukucocwa kweendawo ezihambayo kuya kuncitshiswa, amandla aya kuncitshiswa kwaye i-lubrication iya kuba yimbi.Kwiimeko ezinzima, iingozi ze-cylinder kunye ne-shaft zingenzeka, ezikhokelela ekunciphiseni kwamandla kunye nokunyuka kokusetyenziswa kwamafutha.Ngoko ke, xa ubushushu be-injini ye-diesel ye-generator iphezulu kakhulu, kufuneka ilungiswe kwangethuba.

Ngoko ke, nokuba ishushu okanye i-undercooling, iya kunciphisa ukusebenza kwe-injini kwaye inciphise ubomi benkonzo.Ngoko ke, kubalulekile ukunikela ingqalelo ekutshintsheni ubushushu bamanzi okupholisa.Nje ukuba kwenzeke ingxaki, kufuneka ijongwe kwaye ilungiswe kwangethuba.

Oku ngasentla kwabelwana ngako nguDingbo ijenereyitha yamandla umenzi.Phantsi kweemeko eziqhelekileyo, ubushushu bamanzi okupholisa besethi yejenereyitha yedizili kufuneka bugcinwe kuma-80 ukuya kuma-90 ℃.
