Ioyile ye-air compressor isetyenziselwa kakhulu ukuthambisa iindawo ezihambayo zesilinda ye-compressor kunye nevalvu yokukhupha umoya, kwaye idlala indima yokuthintela umhlwa, ukuthintela ukugqwala, ukuvala kunye nokupholisa.
Ngenxa yokuba i-air compressor ibikwimeko yoxinzelelo oluphezulu, ubushushu obuphezulu kunye namanzi abandayo, ioyile ye-air compressor kufuneka ibe nozinzo oluhle kakhulu lwe-oxidation kubushushu obuphezulu, ukuqokelelwa kwekhabhoni ephantsi, ukusebenza okufanelekileyo kwe-viscosity kunye nobushushu obuqinileyo, kunye nokwahlulwa okuhle kwamanzi eoyile, ukuthintela umhlwa kunye nokumelana nokugqwala.
Imfuneko yokusebenza
1. Umgangatho weoyile esisiseko kufuneka ube phezulu
Ioyile esisiseko yeoyile yecompressor inokwahlulwahlulwa ibe ziindidi ezimbini: uhlobo lweoyile yeminerali kunye nohlobo lweoyile yokwenziwa. Imveliso yeoyile yecompressor yeoyile yeminerali ngokubanzi yenziwa ngokucocwa kwesolvent, ukucocwa kwesolvent dewaxing, ihydrogenation okanye inkqubo yokucoca isongezelelo sodongwe ukuze kufunyanwe ioyile esisiseko, uze emva koko wongeze iintlobo ngeentlobo zezongezo ukuze kudityaniswe.
Ioyile esisiseko yeoyile yecompressor ngokubanzi ibandakanya ngaphezulu kwe-95% yeoyile egqityiweyo, ngoko ke umgangatho weoyile esisiseko unxulumene ngokuthe ngqo nomgangatho wemveliso yeoyile yecompressor, kwaye umgangatho weoyile esisiseko unobudlelwane ngqo nobunzulu bayo bokucoca. Ioyile esisiseko enobunzulu bokucoca obunzulu ayinazo ii-aromatics ezinzima kakhulu kunye nomxholo we-gum. Ikhabhoni eseleyo iphantsi, uvakalelo lwe-antioxidant lulungile, umgangatho weoyile esisiseko uphezulu, inomkhwa omncinci wokuqokelela ikhabhoni kwinkqubo yecompressor, ulwahlulo lwamanzi phakathi kweoyile lulungile, kwaye ubomi benkonzo bude kakhulu.
Ioyile yesiseko seoyile yokwenziwa yioyile yokuthambisa eyenziwe ngeoyile yesiseko se-organic liquid efunyenwe ngokwenziwa kweekhemikhali ize idityaniswe okanye yongezwe nezinye izinto ezahlukeneyo. Uninzi lweeoyile zayo zesiseko ziipolymers okanye ii-molecules eziphezulu ze-organic. Kukho iintlobo ezininzi zeoyile yokwenziwa, kwaye ioyile yokwenziwa esetyenziswa njengeoyile yecompressor ikakhulu ineentlobo ezintlanu ze-hydrocarbon yokwenziwa (i-polyalpha-olefin), i-ester ye-organic (i-ester ephindwe kabini), ioyile yokuthambisa ye-Snott, i-polyalkylene glycol, ioyile ye-fluorosilicone kunye ne-phosphate ester. Ixabiso leoyile yecompressor yeoyile yokwenziwa libiza kakhulu kuneoyile yecompressor yeoyile yeminerali, kodwa inzuzo epheleleyo yezoqoqosho yeoyile yokwenziwa isadlula eyoyile yeminerali eqhelekileyo. Inokuzinza kwe-oxidation, ukutyekela kokuqokelelwa kwekhabhoni encinci, ingadlula ubushushu beoyile yeminerali eqhelekileyo yokuthambisa, ubomi obude benkonzo, ingahlangabezana neemfuno zeoyile yeminerali ngokubanzi.
2. Iinxalenye zeoyile ezisisiseko esincinci
Uphononongo malunga nemeko yokusebenza yeoyile yecompressor lubonisa ukuba ukuphucula ukwakheka kweoyile yesiseko yeyona nto iphambili ekuphuculeni umgangatho weoyile yecompressor. Emva kokuba ioyile yecompressor eyenziwe zizinto ezikhanyayo nezinzima ifakwe kwisilinda yecompressor, izinto ezikhanyayo zishiya inxalenye yokusebenza kwangaphambili ngenxa yokuguquguquka okugqithisileyo, okuchaphazela isiphumo sokuthambisa, kwaye izinto eziphinda zihlangane azikwazi ukuphuma ngokukhawuleza kwindawo yokusebenza emva kokugqiba umsebenzi ngenxa yokuguquguquka okubi, kwaye kulula ukwenza iidipozithi zekhabhoni phantsi kwesenzo sobushushu kunye neoksijini ixesha elide. Ke ngoko, phantsi kweemeko ezinjalo, ioyile yokuthambisa kufuneka ikhethwe njengenxalenye encinci yeoyile yenxalenye, kwaye akufuneki ikhethwe njengomxube weenxalenye ezininzi zeoyile yenxalenye.
Ioyile yecompressor enguNombolo 19 yenziwe ngeoyile ye-distillate ebanzi equlethe izinto ezininzi eziseleyo, kwaye ubungakanani bekhabhoni eqokelelweyo kwicompressor busetyenziswa kakhulu. Ke ngoko, ukuze kuphuculwe umgangatho weoyile yecompressor, izinto eziseleyo kwioyile yecompressor enguNombolo 19 kufuneka zisuswe kwaye kukhethwe ioyile yesiseko se-distillate encinci.
3. Ubukhulu be-viscosity bufanele ukuba bufanelekile
Phantsi kwemeko yokuthambisa okunamandla, ubukhulu befilimu yeoyile buyanda ngokwanda kwe-oyile, kodwa ukungqubana kuyanda ngokwanda kwe-oyile. Ioyile yokuthambisa ene-viscosity ephantsi kakhulu akulula ukwenza ifilimu yeoyile enamandla ngokwaneleyo, eya kukhawulezisa ukuguguleka kwaye inciphise ubomi benkonzo yamalungu. Ngokwahlukileyo koko, i-viscosity yeoyile yokuthambisa iphezulu kakhulu, eya kwandisa ukungqubana kwangaphakathi, yandise amandla athile e-compressor, nto leyo ebangela ukwanda kokusetyenziswa kwamandla kunye nokusetyenziswa kwepetroli, kwaye ikwadala iidiphozithi kwi-groove yeringi yepiston, i-valve yomoya, kunye nomjelo wokukhupha. Ke ngoko, ukukhetha i-viscosity efanelekileyo yingxaki ephambili yokukhetha ngokuchanekileyo ioyile ye-compressor. IYunivesithi yaseXi 'an Jiaotong ibonakalise ngovavanyo ukuba: ukusebenzisa iimeko ezifanayo zovavanyo kuhlobo olufanayo lwe-compressor, ukusetyenziswa kwe-viscosity grades ephantsi yeoyile kunokusetyenziswa kwe-viscosity grades ephezulu yeoyile kunokunciphisa amandla athile e-compressor malunga ne-10% ubuninzi, kwaye ubungakanani bokuguguleka kwamalungu abuhlukanga kakhulu. Ngoko ke, phantsi kwengcamango yokuqinisekisa ukuthambisa, ukukhethwa komgangatho we-viscosity ofanelekileyo weoyile kunempembelelo ebaluleke kakhulu ekongeni amandla kunye nokusebenza okuthembekileyo kwe-compressor.
