Ukuhlukaniswa kwama-grease ama-bearings

Ukuhlukaniswa ngo-1 ngohlobo lokujiya (Indlela yokuhlukaniswa eyinhloko kakhulu)

Isithambisi sisebenza njengesiponji, simunca uwoyela oyisisekelo ngaphakathi kwaso ukuze sakhe isakhiwo esifana ne-paste. Sinquma ukumelana nokushisa, ukumelana namanzi, ukuqina komshini kanye nokuhambisana kwamafutha.

 

1.Amafutha asekelwe ku-lithium

Izici: Isebenziseka kakhulu futhi isetshenziswa kabanzi. Inamandla okuqina okuhle kwemishini, ukumelana namanzi, ukuvimbela ukugqwala kanye nokumelana nokushisa okuphakathi.

Izinhlobo ezivamile

Igrisi esekelwe ku-lithium ejwayelekile: Ihlangabezana nezidingo zokugcoba zama-bearings amaningi ekushiseni okujwayelekile kanye nesivinini esiphakathi nesiphansi.

Igrisi esuselwa ku-lithium ecindezeleke kakhulu: Ingezwe nezithasiselo ezivimbela ukuguguleka ezicindezela kakhulu (njenge-molybdenum disulfide), ifanele ama-bearings angaphansi komthwalo omkhulu noma umthwalo wokushaqeka.

Amafutha asekelwe ku-lithium ayinkimbinkimbi: Ngokuhlanganisa namanye ama-asidi, indawo yokuwa (efinyelela ngaphezu kuka-260℃) kanye nokuphila kwenkonzo yokushisa okuphezulu kuthuthukiswe kakhulu, futhi ukusebenza kwawo kuphakeme kunokwamafutha asekelwe ku-lithium ajwayelekile.

Ukusetshenziswa: Ihlanganisa ngaphezu kwama-80% ezimo zokuthambisa ezivamile, kusukela ezintweni zasendlini kuya ezimotweni zezimboni kanye namasondo ezimoto.

 

2.Amafutha e-Polyurea

Izici: Ukusebenza okuhle kakhulu okuthatha isikhathi eside ekushiseni okuphezulu, ukuqina kwe-oxidation kanye nokuphila isikhathi eside kwenkonzo. Inephuzu lokuwa eliphezulu, ayinazo i-ion zensimbi, futhi ingavimbela i-oxidation kawoyela oyisisekelo. Inomsindo omuhle, kodwa izindleko ziphezulu kakhulu.

Isicelo: Ama-Motor Bearings (ikakhulukazi ama-motor asebenza kahle kakhulu kanye nama-motor anemvamisa eguquguqukayo), ama-bearings ezindaweni ezishisa kakhulu zemishini yensimbi, kanye nama-bearings anembile adinga imijikelezo emide yokugcoba.

 

3.Amafutha asekelwe ku-calcium

Izici: Ukumelana kahle kwamanzi, kodwa ukumelana nokushisa okubi (iphuzu lokwehla cishe ku-80-100℃), kanye nokuqina okujwayelekile komshini. Kancane kancane ithathelwa indawo ama-ester asekelwe ku-lithium.

Ukusetshenziswa: Ivame ukusetshenziswa ezindaweni ezimanzi, ezinesivinini esiphansi kanye nezinomthwalo olula, njengemishini yezolimo kanye nama-bearings ephampu yamanzi.

 

4.Amafutha ahlanganisiwe asekelwe ku-calcium sulfonate

Isici: Igrisi "ephelele" esebenza kahle kakhulu. Ihlanganisa ukucindezela okukhulu kanye nokumelana nokuguguleka, ukumelana namanzi, ukuvimbela ukugqwala, ukuqina kokushisa okuphezulu kanye nokumelana nokugqwala, futhi inekhono lokuziphilisa. Ingumkhiqizo ophumayo osezingeni eliphezulu.

Ukusetshenziswa: Ama-bearings ezimweni zokusebenza ezinzima, njengalezo ezisebenza ngensimbi, ezimayini, ekwenzeni amaphepha, ezisekelweni zasogwini lolwandle, nakwezinye izindawo zemidiya ezisindayo, ezinomswakama, nezingcolisayo.

 

5. Amafutha asekelwe ku-Bentonite

Izici: Isithambisi esingakhiqizi lutho, asinawo iphuzu lokuconsa, ukumelana okuhle nokushisa okuphezulu (kuye ngokuthi uwoyela oyisisekelo), kodwa ukuqina okungekuhle kwemishini futhi kungase kungasebenzi kahle uma kuvezwa emanzini.

Ukusetshenziswa: Isetshenziswa ezindaweni ezinokushisa okuphezulu kanye nesivinini esiphansi, njengezibhebhe zemishini ethile yokubhaka.

6. Amafutha asekelwe ku-aluminium

Izici: Ukunamathela okuhle kanye nokumelana namanzi, kodwa ukuzinza okungekuhle kwemishini futhi akumelani nokushisa.

Isicelo: Isetshenziswa kakhulu kuma-bearings asheshayo emikhunjini, imishini yasolwandle nakwamanye amadivayisi athintana namanzi isikhathi eside.

Ii. Ukuhlukaniswa ngohlobo lwamafutha ayisisekelo

Uwoyela oyisisekelo uyingxenye yamafutha edlala indima yokugcoba ngempela, ebalelwa cishe ku-90%.

 

1. Amafutha asekelwe kumafutha amaminerali

Izici: Izindleko eziphansi, ukusebenza okulinganiselayo, kanye nokusetshenziswa okubanzi kakhulu. Kodwa-ke, ukusebenza kwayo okushisa okuphezulu, okushisa okuphansi kanye nokuqina kwe-oxidation akukuhle njengamafutha okwenziwa.

Isicelo: Izimo zokusebenza ezijwayelekile nezijwayelekile.

 

2. Amafutha asekelwe kumafutha okwenziwa

Izici: Isebenzisa i-PAO (polyalphaolefin), uwoyela we-ester, njll. njengamafutha ayisisekelo. Ibonisa ububanzi obukhulu bokushisa (ukusebenza okuhle kokuqala kokushisa okuphansi kanye nokuqina okuqinile kokushisa okuphezulu), impilo yesevisi ende, ukuguquguquka okuphansi kanye nokuqina okuhle kwe-oxidation.

Izinhlobo ezivamile

Ama-lipid asekelwe ku-Pao: Ngokusebenza okuhle kakhulu okuphelele, ayisinqumo esiyinhloko sama-lipid okwenziwa asebenza kahle kakhulu.

Amafutha asekelwe ku-ester oil: Avame ukusetshenziswa ezimweni lapho kunezidingo ezikhethekile zokuhambisana nezinto.

Ukusetshenziswa: Izindawo zokushisa okukhulu (njengezindawo ezibandayo, izimoto ze-oven ezishisa kakhulu), ama-bearings ashesha kakhulu, ama-bearings ahlala isikhathi eside angenakho ukulungiswa, kanye nama-bearings ezinsimbi anembile.

 

Iii. Ukuhlukaniswa Ngokusebenza kanye Nezithasiselo

Izithasiselo zisetshenziselwa ukuthuthukisa noma ukuqinisa amafutha anezakhiwo ezithile ezithile.

 

1. Amafutha aqeda ukuguguleka ngokweqile

Izici: Yengezwa ngezinto ezicindezela kakhulu njenge-sulfur, i-phosphorus kanye ne-chlorine, noma izinto eziqinile zokulwa nokuguguleka njenge-molybdenum disulfide kanye ne-graphite, ezingakha ifilimu evikelayo ngaphansi kwemithwalo ephezulu.

Isicelo: Ama-gearbox aqinile, ama-rolling mill bearings, ama-bearings emishini yokumba.

 

2. Ama-lipids okushisa aphezulu naphansi

Izici: Ukusebenzisa uwoyela wesisekelo wokwenziwa kanye ne-compound thickener, kuqinisekisa ukuthi akukho ukuqina emazingeni okushisa aphansi kakhulu futhi akukho ukulahleka noma ukubilisa emazingeni okushisa aphezulu kakhulu.

Isicelo: Ama-bearings ezindiza, ama-bearings ezimoto ezikhethekile, ama-bearings emishini yokuqandisa.

 

3. Amafutha okulwa nokugqwala nokulwa nokugqwala

Izici: Ifakwe ngezithiyo ezinamandla zokugqwala kanye nama-passivator.

Ukusetshenziswa: Ama-Bearings ezindaweni zasemanzini, izindawo ezibola ngamakhemikhali, noma ama-bearings emishini adinga ukugcinwa isikhathi eside ukuze agcinwe.

4. Amafutha ebanga lokudla

Izici: Zonke izithako zihambisana nezindinganiso zokuphepha kokudla njenge-NSF H1, futhi azinabo ubuthi futhi azinaphunga.

Isicelo: Amabheringi emishini yokucubungula ukudla, imishini yemithi, kanye nemigqa yokugcwalisa iziphuzo ukuvimbela ukungcoliswa komkhiqizo.

Iv. Ungayikhetha Kanjani I-Bearing Grease Efanele?

Lapho ukhetha, isimiso esithi "STAMP" kufanele sicatshangelwe ngokuphelele:

 

Isivinini S (Isivinini):Uma ijubane lokujikeleza liphezulu, i-viscosity yamafutha ayisisekelo iyancipha, kulapho ukuzinza komshini kuba ngcono futhi ukuthamba kufanele kukhethwe ukuze kuncishiswe ukushisa okukhiqizwa ngesikhathi sokuxubha.

 

T - Izinga lokushisa: Ububanzi bokushisa bokusebenza bunquma uhlobo lwamafutha ayisisekelo (amafutha amaminerali/amafutha okwenziwa) kanye nohlobo lwesithambisi.

 

Isicelo se-A/Ambient:Ingabe kukhona amanzi, uthuli noma amakhemikhali? Lokhu kunquma izidingo zokumelana namanzi, ukuvimbela ukugqwala kanye nokumelana nokugqwala.

 

Umthwalo we-M (Umthwalo):Amafutha okucindezela okukhulu okulwa nokuguguleka kufanele akhethwe uma kukhulunywa ngemithwalo esindayo noma imithwalo yokushayisana.

 

Isikhathi (Umjikelezo wokugcoba):Uma ufisa ukwandisa umjikelezo wokushintsha amafutha noma ukufeza ukusebenza okungenakulungiswa, kufanele ukhethe amafutha asekelwe kumafutha okwenziwa noma amafutha e-polyurea ahlala isikhathi eside.

 

Ukukhethwa kwamafutha okuthwala kuwubuciko bokulinganisela. Kusukela kumafutha amaminerali asekelwe ku-lithium asezingeni eliphezulu kwezomnotho kuya kumafutha okwenziwa e-polyurea/complex calcium sulfonate asebenza kahle kakhulu, izinhlelo zawo zokuhlela zihambisana ngqo nezimo zokusebenza ezahlukene kanye nezinselele. Ukukhetha okulungile kuyisixhumanisi esibalulekile sokuqinisekisa ukuthembeka kwama-bearings nokwandisa impilo yawo yenkonzo.
