Igrisi esetyenziselwa izinto ezininzi inokugubungela usetyenziso oluninzi iyenza inqweneleke ekucutheni uluhlu lwempahla kunye neendleko ezinxulumene noko, kunye nokwenza lula inkqubo yokuthambisa.Ngokubanzi, igrisi ezininzi ze-lithium zijiyile kwaye zine-Antiwear (AW) kunye / okanye i-Extreme Pressure (EP) izongezo kunye ne-oyile yesiseko kunye ne-viscosity ukusuka kwi-SAE 30 ukuya kwi-SAE 50.

Kodwa iigrisi ezisetyenziselwa izinto ezininzi azikwazi ukuphatha zonke izicelo kwindawo yoshishino eqhelekileyo.Ukuze siqonde igrisi, kufuneka sijonge ukwakheka kwegrisi.Igrisi ngokwenyani yenziwe zizinto ezintathu;isiseko sesitokisi okanye isitokhwe, i-thickener kunye nezongezo.

Xa kuqwalaselwa igrisi, imiba jikelele ekufuneka iqwalaselwe ibandakanya;

• Uhlobo lweGrisi Thickener
• Uhlobo lwe-Fluid esisiseko
• Base Fluid Viscosity
• IiMfuno ezongezelelweyo
• IBanga le-NLGI

Kwakhona qwalasela iimeko zokusingqongileyo zesicelo.Uluhlu lweqondo lokushisa kunye nendawo yesicelo luyimfuneko ukuvavanya iimeko apho igrisi kufuneka yenze.Iimeko ezimanzi kunye neemeko ezinothuli zifuna ukubuyisela rhoqo rhoqo ukunceda ukugcina ezi zingcolisa ngaphandle kwamacandelo.Kwakhona qwalasela ubushushu bokusebenza kwesicelo kunye nolungiselelo lokubuyisela kwakhona ukufumanisa eyona mveliso ilungileyo enokusetyenziswa kunye neyona ndlela ilungileyo yokugalela igrisi.Ukude okanye kunzima ukufikelela kwiindawo zenza imeko yezithambisi ezizenzekelayo.Ukususela kuhlobo lweoli yesiseko kunye nombono we-viscosity, imigangatho yokushisa egqithisileyo kufuneka ifakwe kwisigqibo malunga nokuba yiyiphi igrisi yokukhetha.

Izityebi zegrisi zininzi ngenani kwaye ezinye zineempawu ezizodwa kunye neenzuzo.Ezinye iintlobo ze-thickener zingongeza iimpawu zokusebenza kwigrisi.Ngokomzekelo, ukuxhathisa kwamanzi kunokuphuculwa xa kusetyenziswa i-aluminium complex okanye i-calcium complex thickeners.Kukho i-advanteji yobushushu ukuba ezinye ii-thickeners zinezinye.Ukuhambelana okutyebileyoyeyona nto ixhalabisayo.NaziIitshathi zokuNxibelelana ezityebileyoekhoyo ukuba iqwalaselwe, kodwa eyona ndlela ilungileyo kukudibana nomboneleli wakho ukubona ukuba balwenzile na uvavanyo lokuhambelana neentlobo ezahlukeneyo zokujiya.Ukuba akunjalo, uvavanyo lokuhambelana negrisi lunokuqhutywa ngamakhulu ambalwa eedola ukuqinisekisa ngokuchasene nemiba yokuhambelana.

Izitokhwe ezisisiseko ezisetyenziswa kwiigrisi zidla ngokuba yioyile yeminerali, imixube eyenziweyo okanye isitokhwe esipheleleyo sokwenziwa.I-Polyalphaolefin (PAO) i-oyile yokwenziwa isetyenziswa rhoqo, njengoko ezi zihambelana ne-oyile yesiseko samaminerali.Olunye ulwelo olwenziwayo olusetyenziswa ekwenzeni igrisi lubandakanya ii-esters, ulwelo lwe-silicone, iiPerfluoropolyethers, kunye nezinye izinto zokwenziwa kunye nemixube yokwenziwa.Kwakhona, ukuhambelana kwe
isiseko sesitokhwe (s) esisetyenziswa kwiigrisi ezahlukeneyo asiqinisekanga.Jonga igrisi ivelisa idatha ukuze ubone ukuba ichaza uhlobo lweoyile yesiseko.Ukuba kukho ukuthandabuza, qhagamshelana nomthengisi ukuze ufumane ingcaciso engaphezulu malunga nohlobo lwe-base fluid esetyenziswe kwigrisi yomviwa.Yijonge ukuba iyahambelana na nolwelo olusisiseko olusetyenziswa kwigrisi esebenzayo ngoku.Khumbula ukubaI-Viscosity yolwelo olusisiseko olusetyenziswa kwigrisi kufuneka lutshatiswe ngokusondeleyo kangangoko kwiimfuno zeSpeed, umthwalo kunye noBushushu besicelo..

Izongezo ezibandakanyiweyo kwiigrisi zidla ngokuba zii-antioxidants, irust kunye ne-corrosion inhibitors, kunye ne-antiwear okanye uxinzelelo olugqithisileyo (EP) additives.Izongezo ezikhethekileyo zingafuneka ukwandisa ukusebenza.I-adhesive kunye ne-lubricants eqinile njenge-Molybdenum Disulfide (i-Moly) yongezwa kwigrisi ukunika ukhuseleko olongezelelweyo xa iimeko zigqithise okanye ukubuyisela ukubuyisela kunzima ukufezekisa.

National Lubricating Grease Institute (NLGI) AmaBanga ngumlinganiselo wegrisiukungaguquguquki.Oko kuthetha ukuba ilinganisa ukuqina kwegrisi okanye ukuthamba nge-ASTM D 217, uvavanyo lwe "Cone Penetration of Lubricating Grease".Kukho "amabanga" asithoba e-NLGI ahlukeneyo aquka i-000, 00, 0, 1, 2, 3, 4, 5 kunye ne-6. Sonke siqhelene negrisi "EP 2".Oku kusixelela izinto ezimbini, i-EP 2 grease yiNLGI yeBanga lesi-2 kwaye yomelezwe ngezongezo zoxinzelelo olugqithisileyo (EP).Oku akusixeleli enye into malunga nohlobo lwe-thickener, uhlobo lwe-oyile yesiseko okanye i-viscosity ye-oyile yesiseko.Ibakala elichanekileyo le-NLGI liyingqwalasela ebalulekileyo kuba ayizizo zonke izicelo zegrisi ezifanayo.Ezinye izicelo zegrisi zifuna igrisi ethambileyo ukuze impontshwe ngokulula ngemigca emincinci yokuhambisa kunye neevalvu.Ngelixa ezinye izicelo zegrisi ezifana neebheringi ezifakwe kwishafti ezithe nkqo zifuna igrisi eqinileyo ukuze igrisi ihlale injalo.

Ngayo yonke le miba ekufuneka iqwalaselwe, akumangalisi ukuba kukho ukubhideka malunga negrisi.Uninzi lwezibonelelo zemizi-mveliso kufuneka zikwazi ukusebenzisa iigrisi ezimbalwa eziza kuthambisa indawo yazo ngokupheleleyo.Kufuneka kubekho igrisi ethile:

• IiMoto zoMbane
• Ukudibanisa isantya esiphezulu
• Isantya esiphantsi Couplings
• Izicelo eziLayishwa kakhulu/ezicothayo
• Izicelo zokuGcisa ngokubanzi

Ukongeza, igrisi enye okanye ezimbini ezikhethekileyo zinokufuneka kwizicelo ezigqithisileyo.

Iigrisi kunye nezixhobo zokukhupha igrisi kufuneka zifakwe umbala kwaye zibhalwe ukuze zingaphambanisi iimveliso ezingcolisekileyo.Sebenza nomthengisi wakho ukuze wazi kwaye uqonde iigrisi ezisetyenziswa kwiziko lakho.Xa ukhetha igrisi, ziqhelanise ngokucokisekileyo kwaye ukhethe igrisi elungileyo kwisicelo.
