Oiri sefa mudziyo

imwe neimwe yemukati yekupisa injini inosanganisira akawanda simbi zvikamu izvo zvinogara uye zvakanyanya kushingaira kupindirana nemumwe. Wese munhu anonyatsoziva kuti unlubricated mechanism haishande nemazvo uye haigare kwenguva refu. Zvikamu zvefriction zvinosakara, zvichikonzera machipisi madiki anovhara maburi pakati pezvikamu uye kuita kuti basa remakanika rinyanye kuoma. Zvose izvi zvinoperekedzwa nekusunungurwa kwehuwandu hwekupisa, izvo zvinogona kutungamirira mukupisa kwejini inopisa mukati uye pakupedzisira kuidzima.

Lubrication inobatsira kuderedza kuipa kwekukweshana. Oiri inotenderera murubrication system inobvisa zvimedu zvesimbi zvakaumbwa nekuda kwekukweshana, pamwe nemarara madiki kubva mukati meinjini yekupisa. Mukuwedzera, kutenderera kwe lubricant kunobatsira iyo inotonhorera kutarisana nekupisa kweinjini yekupisa mukati, zvishoma kubvisa kupisa kubva mairi. Zvakakosha kuyeuka zvakare kuti firimu yemafuta pasimbi inodzivirira kubva pakuora.

Dambudziko chete nderekuti simbi shavings uye mamwe ma mechanical tsvina haanyangari kubva kuvhavha system uye anogona kudzokera kune mukati memoto injini zvakare. Kuti izvi zvisaitike, firita yakakosha yekuchenesa inosanganisirwa mudunhu rekutenderera. Kune seti yemhando dzakasiyana dzemafirita emafuta, asi michina ine mechani yekusefa ndiyo inonyanya kushandiswa.

Dhizaini yesefa inogona kunge isinga patsanurwe kana kupetwa. Panguva imwecheteyo, chimiro chemukati hachina misiyano yakakura.

Chinhu chisina kupatsanurwa chinoraswa chinongotsiviwa kana mafuta matsva akadururwa murubrication system.

Iyo collapsible dhizaini inobvumidza iwe kutsiva imwe chete sefa chinhu.

Muzviitiko zvakawanda, iyo sefa yemafuta yakazara-kuyerera, kureva kuti, vhoriyamu yese yerubricant inopombiswa nepombi inopfuura nepairi.

Mumazuva ekare, mafirita echikamu-yekuyerera aishandiswa zvakanyanya, kuburikidza iyo chikamu chemafuta chaipfuura - kazhinji inenge 10%. Chishandiso chakadaro chinogona kunge chiri icho chega muhurongwa, kana kuti chinogona kushanda chakafanana nefirita yakakora. Ikozvino iwo haawanzo, detergent uye anoparadzira ekuwedzera mune akawanda emazuva ano mamakisi emafuta eICE anoita kuti zvikwanise kupfuudza nesarudzo imwe chete yekuyerera.

Iyo dhigirii yekucheneswa kwemafuta inoratidzwa neiyo parameter sekunaka kwekusefa. Mukuita, ivo vanowanzo reva zita rekuti kusefa kunaka, ndiko kuti, saizi yezvimedu izvo sefa inosefa ne95%. Absolute filtration fineness inoreva 100% kuchengetwa kwezvikamu zveimwe saizi. Mazhinji mafirita emafuta emazuva ano ane zita rekusefa kwakanaka kwe25…35 microns. Izvi, sekutonga, zvakaringana, sezvo zvidiki zvidiki hazvina zvakakomba zvakashata painjini yekupisa yemukati.

Imba yekusefa ndeye cylindrical simbi kapu ine chivharo chepasi, iyo yakakwenenzverwa kana kukungurutswa mune isina kupatsanurwa dhizaini. Seti yemainlets inoiswa pamwe neradius muvhavha, uye chinobuda chine tambo inosungirira chiri pakati. Rubber o-ring inodzivirira kubuda kwegirisi.

Sezvo panguva yekushanda kumanikidzwa kunogona kusvika kune anopfuura 10 atmospheres, zvinodikanwa zvakakomba zvinoiswa pane simba remhosva; inowanzogadzirwa nesimbi.

Mukati meimba yacho mune sefa chinhu chakagadzirwa ne porous material, chinogona kunge chiri bepa kana kadhibhodhi yemagiredhi akakosha ane akakosha impregnation, anonzwa uye akasiyana masynthetics. Iyo corrugated filter element ine dense packing uye inogadzikwa yakatenderedza peforated inodzivirira sleeve. Iyi dhizaini inokubvumira kuti ugadzire nzvimbo yakakura yekusefa mune diki vhoriyamu yegirazi. Uye iyo simbi inodzivirira clip inopa imwe simba uye haitenderi sefa kudonha pasi pekumanikidzwa madonhwe.

Chinhu chakakosha chesefa ndeye bypass (overflow) valve ine chitubu. Kana dzvinyiriro inopfuura imwe chikumbaridzo, vharafu inovhura inovhura kuti mafuta asina kuchena apinde muhurongwa. Mamiriro ezvinhu aya anogona kuitika kana sefa yakasvibiswa zvakanyanya kana viscosity yerubricant yakakwira, semuenzaniso, kana uchitanga injini yekupisa mukati mune chando. Mafuta asina kucheneswa einjini dzinopisa moto uipi husina kusimba kupfuura kuziya kwemafuta kwenguva pfupi.

Iyo anti-drain (cheki) valve inodzivirira mafuta kubva pakuyerera kunze kwesefa mushure mekunge injini yamira. Saka, lubricant inogara ichisiiwa muhurongwa, iyo inenge ichangobva kupihwa kune injini yekupisa yemukati kana yatangwazve. Ivhavha yecheki inonyatso mhete yerabha iyo inovhara zvakasimba ma inlets kana isiri kushandiswa uye inovhura pasi pekumanikidzwa apo pombi yemafuta inotanga.

Iyo dhizaini inosanganisirawo anti-drain valve inodzivirira mafuta kubva mukudurura kunze kwesefa imba panguva yekuchinja sefa.

Kune mamwe marudzi emuchina uyu anosiyana munzira yekucheneswa kunoitwa.

Magnetic filter - inowanzoiswa mupani yemafuta uye inounganidza machipisi esimbi uchishandisa magineti echigarire kana electromagnet. Nguva nenguva, unoda kusunungura magnetic plug uye kuichenesa.

Sefa-sump - pano tsvina inongogara kuzasi kwe sump pasi pesimba regiravhiti, saka iyi sefa inonziwo giravhiti. Pano, kugadzirisa kunoderedzwa kusvika pakusunungura plug uye kubvisa mamwe emafuta akasvibiswa. Mumotokari, mafirita akadaro haachashandiswi, nekuti anenge asina mafomu emhando dzemazuva ano emafuta eICE.

Centrifugal cleaner (centrifuge) - mudziyo wakadaro unowanzo shandiswa muma ICE emarori uye mayuniti emotokari, kunyangwe nguva nenguva inogona kuwanikwawo mumotokari. Mariri, zvimedu zvinorema zvezvisina kuchena pasi pechiito che centrifugal simba chinoitika panguva yekutenderera kwe rotor inobhururuka ichienda kumadziro e centrifuge uye inoramba iri pavari muchimiro che resinous precipitate. Oiri inodyiswa murotor kuburikidza nemugero muaxis yayo pasi pekumanikidzwa uye inobuda nekumhanya kwakanyanya kuburikidza nemanozzles, ichipinda muoiri sump. Jets of lubricant ine zvinosemesa pane rotor, nekuda kweiyo inotenderera.

Nguva yakakurudzirwa yekuchinja sefa yemafuta inogona kusiyana zvichienderana nemuenzaniso wemotokari, asi, sekutonga, iri 10 ... makiromita zviuru makumi maviri zvepetroli ICEs, yeinjini dzedhiziri - 20 ... 1,5 kakawanda. Zviri nyore uye zvinoshanda kuita izvi panguva imwe chete nekutsiva kwakarongwa.

Kana mota ichishandiswa mumamiriro ezvinhu akaoma - kupisa, guruva, nzvimbo ine makomo, kazhinji traffic jam - ipapo nguva yekuchinja lubricant nemafuta sefa inofanira kupfupika.

inogona kusiyana nehuwandu (hukuru), dhigirii rekuchenesa (filter fineness), kuvhura kudzvinyirira kwevhavhavhavha, pamwe chete nehukuru hwemuviri uye tambo yemukati. Aya ma paramita ane hukama nekudzvanywa mune lubrication system, mhando, simba uye akasiyana dhizaini maficha einjini yekupisa yemukati. Kunewo mafirita asina vheji yekuvhara, anoshandiswa mumamiriro ezvinhu apo valve yakadaro iripo mujini pachayo.

Zvese izvi zvinofanirwa kuverengerwa pakusarudza shanduko panzvimbo yechinhu chakashandiswa. Kushandiswa kwesefa isina kufanira kunogona kutungamirira kumigumisiro yakakomba yejini inopisa mukati. Izvo zvine musoro kuisa iwo mafirita anokurudzirwa neautomaker.

Kutsiva sefa yemafuta, sekutonga, hakuna kuoma - inongoputirwa pane yakarukwa fitting, iyo inofanirwa kucheneswa isati yaiswa. Asi kugadzira simba rakakwana, kiyi yakakosha inodiwa.

Kana kuvharwa kwemhepo kwakagadzirwa muhurongwa hwekuzora, kumanikidzwa mukati mayo kuchave kusina kukwana, saka mhepo inofanira kuraswa. Zviri nyore kuita izvi - mushure mekupa sefa zvishoma, shandura crankshaft neinotangira kusvika mafuta atanga kunyura, wobva wasimbisa sefa zvakare.
