Ukukhetha namafutha utshani mowers

Njalo ehlobo, inkathi asebenzayo ukusetshenziswa uphethiloli ubuchwepheshe. Ngisho ezweni lethu, utshani mowers ziye ngenkuthalo esetshenziswa eminyakeni yamuva, ngokuyinhloko waziwa kithi kusuka amafilimu ithelevishini kuphela.

Yiqiniso, ukuthi abasebenzisi mathuluzi kunezinkinga eziningi, njengoba okuhlangenwe nakho emsebenzini wayo efanele sonke. Ikakhulukazi, ikakhulukazi ikhanda kubangela namafutha utshani mowers, ekukhethweni zazo ngisho simple. By the way, kuyoba endaweni kulo mongo, ukusho ukuthi abathengi abaningi baye bazishisa ngokuphelele okungalungile Ukukhetha igrisi zindlela, njengoba umbono eyethile ukusebenza eziyisisekelo ubuchwepheshe abawasebenzisayo.

Isikhathi esining impela, bayalibala ukuthi ngisho namafutha lawnmowers ongakhetha kuzo, ukugxila izinga lokushisa kanye nezinkomba kwemvelo.

Kuyaziwa ukuthi iyiphi uwoyela eyaziwa ezine-unhlangothi izinjini kumele ihlangabezane ukusebenza ezithile Sae viscosity. Yiqiniso, utshani otshanini at ongaphakeme okushisa ambient ikhula kakhulu kabi, ukuze uma uthenga udinga ukugxila imikhiqizo, ogama sibalo kule ipharamitha sifana iminyaka wokusebenza.

Iningi abakhiqizi wathi ukuthi engcono kungaba namafutha lawnmowers, ezifanele Sae 30. Ukusetshenziswa izinhlobo ngaphansi viscous sikhula kahle ezindaweni ezibandayo futhi greases esengeziwe izifunda ashisayo futhi hhayi wamukelekile. Kungani?

Iphuzu elitholakala kulesi design lezi amadivaysi. Ukuze kuncishiswe izindleko bese lula Abaklami yabo ukukhiqizwa iqedwe futha lwamafutha Ukwakheka kwabo. Ngenxa yalokho, Lubrication kuzo zonke izingxenye ezinyakazayo yenjini Kwenziwa ngokusebenzisa le crankshaft, okuyinto e ukuhamba kwayo "Ketha" zikuthola crankcase, ngokulinganayo usabalalisa igrisi by izinkinga zonke izingxenye. Yingakho uwoyela for uphethiloli utshani mowers ayinakukuthenga ku esitolo lokuqala, njengoba ungase kamuva "ubusiswa" akhawunti iyokhandwa yayo.

Ngakho, lapho uketshezi kakhulu ukungaguquguquki lubricating Ukwakheka yokugcina uyomane ubaleka ngemuva crankshaft ku crankcase. Uma emaningi kakhulu, izidakamizwa ke angagcina ibe mass amorphous okuqinile, okungadingi zifeza okuhle.

Izimoto futhi ezingcono kakhulu bavikelekile izinkathazo ezinjalo, njengoba i-ukufana we Lubrication injini lapho okuhambelana ekhethekile futha uwoyela. Kwakucatshangwa ukuthi konke namafutha utshani mowers ingasetshenziswa izimoto, kodwa imikhiqizo ejwayelekile emshinini musa njalo uvumelane nezinye izimoto.

Ngenhlanhla, cishe zonke ezikhethekile amaketanga okudayisa ukudayiswa lamafutha Lubrication grade Sae 30. Lokho Izitolo ezinjalo kuphela hhayi kuyo yonke imizi, ingasaphathwa emadolobheni amancane. Ngakho onjani uwoyela ukuze uthele wotshani utshani ngokungabi bikho ongakhetha ethize?

Ochwepheshe bathi ngenxa yale njongo, kangcono igrisi grade Sae 15W-40 futhi Sae 20W-50. Futhi ukuthengwa "zokwenziwa" noma uwoyela amaminerali akunandaba, njengoba wotshani Namanje hhayi esetshenziswa ezimweni ezinzima ngokulinganayo, kulokho has ukugibela imoto yomjaho.
