Kugawa mafuta a mabearing

Kugawa kwa I ndi Mtundu Wokhuthala (Njira yofunikira kwambiri yogawa)

Chokhuthala chimagwira ntchito ngati siponji, kutengera mafuta oyambira mkati mwake kuti apange kapangidwe kofanana ndi phala. Chimatsimikiza kukana kutentha, kukana madzi, kukhazikika kwa makina komanso kugwirizana kwa mafuta.

 

1.Mafuta ochokera ku lithiamu

Mawonekedwe: Yogwiritsidwa ntchito mosiyanasiyana komanso yogwiritsidwa ntchito kwambiri. Ili ndi kukhazikika kwabwino kwa makina, kukana madzi, kupewa dzimbiri komanso kukana kutentha kwapakati.

Mitundu yodziwika bwino

Mafuta opangidwa ndi lithiamu ogwiritsidwa ntchito nthawi zonse: Amakwaniritsa zofunikira za mafuta ofunikira a mabearing ambiri pa kutentha kwabwinobwino komanso liwiro lapakati ndi lotsika.

Mafuta opangidwa ndi lithiamu wopanikizika kwambiri: Owonjezeredwa ndi zowonjezera zotsutsana ndi kupsinjika kwambiri (monga molybdenum disulfide), ndi oyenera ma bearing omwe ali ndi katundu wambiri kapena kugwedezeka.

Mafuta opangidwa ndi lithiamu ovuta: Mwa kuphatikiza ndi ma asidi ena, nthawi yogwiritsira ntchito mafuta (mpaka 260℃) komanso kutentha kwambiri kwakhala bwino kwambiri, ndipo magwiridwe ake ndi apamwamba kuposa mafuta wamba opangidwa ndi lithiamu.

Kugwiritsa Ntchito: Imagwira ntchito zoposa 80% ya zinthu zodzoladzola zachikhalidwe, kuyambira zida zapakhomo mpaka ma mota amafakitale ndi mawilo amagalimoto.

 

2.Mafuta a polyurea

Mawonekedwe: Imagwira ntchito bwino kwambiri kutentha kwambiri, imakhala yokhazikika mu okosijeni komanso imakhala nthawi yayitali yogwira ntchito. Ili ndi malo otsika kwambiri, yopanda ma ayoni achitsulo, ndipo imatha kuletsa okosijeni wa mafuta oyambira. Ili ndi phokoso labwino, koma mtengo wake ndi wokwera.

Ntchito: Mabeya a Magalimoto (makamaka ma mota ogwira ntchito bwino kwambiri komanso ma mota osinthasintha), ma bearing m'malo otentha kwambiri m'mafakitale achitsulo, ndi ma bearing olondola omwe amafunikira nthawi yayitali yopaka mafuta.

 

3.Mafuta ochokera ku calcium

Mawonekedwe: Imalimbana bwino ndi madzi, koma imalimbana ndi kutentha pang'ono (kutsika pafupifupi 80-100℃), komanso imakhazikika pamakina. Pang'onopang'ono imasinthidwa ndi ma esters okhala ndi lithiamu.

Kugwiritsa Ntchito: Kawirikawiri imagwiritsidwa ntchito m'malo onyowa, othamanga pang'ono komanso opepuka, monga makina a zaulimi ndi mabearing a pampu yamadzi.

 

4.Mafuta opangidwa ndi calcium sulfonate

Mbali: Mafuta odzola "ozungulira" amphamvu kwambiri. Amaphatikiza kukana kuthamanga kwambiri ndi kutopa, kukana madzi, kupewa dzimbiri, kukhazikika kutentha kwambiri komanso kukana dzimbiri, komanso amatha kudzichiritsa okha. Ndi chinthu chapamwamba kwambiri chomwe chikubwera.

Kugwiritsa Ntchito: Mabeyala a ntchito zovuta, monga za zitsulo, migodi, kupanga mapepala, nsanja za m'mphepete mwa nyanja, ndi malo ena olemera, chinyezi, komanso owononga zinthu.

 

5. Mafuta ochokera ku Bentonite

Zinthu Zake: Chokhuthala chosapangidwa ndi zinthu zachilengedwe, sichimadontha madzi, chimatha kupirira kutentha kwambiri (kutengera mafuta oyambira), koma sichimakhazikika bwino ndipo chimatha kulephera kugwira ntchito chikakumana ndi madzi.

Kugwiritsa Ntchito: Kumagwiritsidwa ntchito m'malo otentha kwambiri komanso othamanga pang'ono, monga mabearing a zida zina zophikira.

6. Mafuta ochokera ku aluminiyamu

Zinthu Zake: Kumamatira bwino komanso kukana madzi, koma kukhazikika kwa makina komanso kukana kutentha.

Kugwiritsa Ntchito: Amagwiritsidwa ntchito makamaka pa mabearing otsika liwiro m'zombo, zida zapamadzi ndi zida zina zomwe zimakhudzidwa ndi madzi kwa nthawi yayitali.

II. Kugawa mafuta motsatira mtundu wa mafuta oyambira

Mafuta oyambira ndi gawo la mafuta lomwe limagwira ntchito yopaka mafuta, pafupifupi 90%.

 

1. Mafuta ochokera ku mafuta a mchere

Zinthu Zake: Mtengo wotsika, magwiridwe antchito abwino, komanso kugwiritsidwa ntchito kwakukulu. Komabe, magwiridwe ake otentha kwambiri, kutentha kochepa komanso kukhazikika kwa okosijeni sikwabwino ngati mafuta opangidwa.

Kugwiritsa Ntchito: Mikhalidwe yogwirira ntchito yanthawi zonse komanso yachizolowezi.

 

2. Mafuta opangidwa ndi mafuta

Mawonekedwe: Imagwiritsa ntchito PAO (polyalphaolefin), mafuta a ester, ndi zina zotero ngati mafuta oyambira. Ili ndi kutentha kosiyanasiyana (kuyambira bwino kutentha kotsika komanso kukhazikika kwamphamvu kutentha kwambiri), nthawi yayitali yogwira ntchito, kusinthasintha kochepa komanso kukhazikika kwabwino kwa okosijeni.

Mitundu yodziwika bwino

Ma lipids okhala ndi Pao: Ndi magwiridwe antchito abwino kwambiri, ndi omwe amasankhidwa kwambiri pa lipids zopangidwa bwino kwambiri.

Mafuta ochokera ku mafuta a Ester: Nthawi zambiri amagwiritsidwa ntchito pakakhala zofunikira zapadera kuti zinthu zigwirizane.

Kugwiritsa Ntchito: Malo otentha kwambiri (monga madera ozizira, magalimoto a uvuni otentha kwambiri), mabearing othamanga kwambiri, mabearing osasamalira nthawi yayitali, ndi mabearing a zida zolondola.

 

III. Kugawa Magulu ndi Magwiridwe Abwino ndi Zowonjezera

Zowonjezera zimagwiritsidwa ntchito kuwonjezera kapena kupatsa mafuta okhala ndi zinthu zinazake.

 

1. Mafuta oletsa kuvala kwambiri

Zinthu Zake: Imawonjezedwa ndi zinthu zolimbitsa thupi kwambiri monga sulfure, phosphorous ndi chlorine, kapena zinthu zolimba zoletsa kukalamba monga molybdenum disulfide ndi graphite, zomwe zimatha kupanga filimu yoteteza pansi pa katundu wambiri.

Kugwiritsa ntchito: Mabearing a gearbox olemera, mabearing a mill rolling, mabearing a makina a migodi.

 

2. Mafuta otentha kwambiri komanso otsika

Zinthu Zake: Pogwiritsa ntchito mafuta oyambira opangidwa ndi mankhwala okhuthala, samapangitsa kuti mafutawo aziuma kutentha kwambiri komanso kuti asatayike kapena kuphikidwa kutentha kwambiri.

Kugwiritsa ntchito: Ma bere a ndege, ma bere apadera a magalimoto, ma bere a zida zoziziritsira.

 

3. Mafuta oletsa dzimbiri komanso oletsa dzimbiri

Zinthu Zake: Yawonjezeredwa ndi zoletsa zamphamvu za dzimbiri ndi zoletsa kuzizira.

Kugwiritsa Ntchito: Mabeyala m'malo okhala ndi zinthu zowononga zachilengedwe, malo okhala ndi mankhwala, kapena mabeyala a zida zomwe ziyenera kusungidwa kwa nthawi yayitali kuti zisungidwe.

4. Mafuta ofunikira pa chakudya

Zinthu: Zosakaniza zonse zimagwirizana ndi miyezo yotetezera chakudya monga NSF H1, ndipo sizowopsa komanso zopanda fungo.

Kugwiritsa Ntchito: Mabeyala a makina opangira chakudya, makina opangira mankhwala, ndi mizere yodzaza zakumwa kuti apewe kuipitsidwa kwa zinthu.

Iv. Kodi Mungasankhe Bwanji Mafuta Oyenera Opangira Chidebe?

Posankha, mfundo ya "STAMP" iyenera kuganiziridwa mokwanira:

 

Liwiro la S (Liwiro):Liwiro lozungulira likakwera, kukhuthala kwa mafuta oyambira kumachepa, kukhazikika kwa makina kumakhala bwino komanso kusinthasintha kuyenera kusankhidwa kuti kuchepetse kutentha komwe kumachitika mukasakaniza.

 

T - Kutentha: Kuchuluka kwa kutentha komwe kumagwira ntchito kumatsimikiza mtundu wa mafuta oyambira (mafuta amchere/mafuta opangidwa) ndi mtundu wa chokhuthala.

 

A-Kugwiritsa Ntchito/Kuzungulira:Kodi pali madzi, fumbi kapena mankhwala? Izi zimatsimikizira zofunikira pa kukana madzi, kupewa dzimbiri komanso kukana dzimbiri.

 

M-Katundu (Katundu):Mafuta oletsa kutopa kwambiri ayenera kusankhidwa kuti agwiritsidwe ntchito ponyamula katundu wolemera kapena wolemera kwambiri.

 

Nthawi (Nthawi yopaka mafuta):Ngati mukufuna kuwonjezera nthawi yosinthira mafuta kapena kugwira ntchito popanda kukonza, muyenera kusankha mafuta opangidwa ndi mafuta opangidwa ndi mafuta kapena mafuta a polyurea omwe amakhala nthawi yayitali.

 

Kusankha mafuta onyamula ndi luso lolinganiza zinthu. Kuyambira mafuta amchere ochokera ku lithiamu omwe ndi olemera kwambiri mpaka mafuta opangidwa ndi polyurea/complex calcium sulfonate, machitidwe awo ogawa zinthu amafanana mwachindunji ndi mikhalidwe yosiyanasiyana yogwirira ntchito ndi zovuta. Kusankha kolondola ndi njira yofunika kwambiri yotsimikizira kudalirika kwa mabearing ndikuwonjezera nthawi yawo yogwirira ntchito.
