Sei mashandiro epurasitiki ari nani pane esimbi

 

1. Tarisiro yekuvandudzwa kwemabheringi epurasitiki

Parizvino, vatengi vazhinji vari zvichiri vanoda kusarudza simbi yekuisa midziyo. Pamusoro pezvose, kana mabheyaringi epurasitiki asina kugadzirwa, mabheyaringi esimbi aigara achishandiswa sezvinhu zvechinyakare. Asi kusvika pari zvino, mashandiro emabearing epurasitiki achava nani uye ari nani mune ramangwana.

2.Zvinhu zvepurasitiki zvinotakura zvinhu uye zvakanakira

TMutengo wekugadzira mapurasitiki wakaderera pane wesimbi, uye mhando dzakasiyana dzezvinhu zvepurasitiki dziri kuwedzera kupfuma. uyeinoshandiswa mumaindasitiri akawanda, zvinhu zvepurasitiki zvakajairikazvinhu zvakaita senylon, polytetrafluoroethylene, polyethylene uye PEEK.

Iyo mabheyaringi epurasitiki is Kushandiswa kwakasiyana-siyana, kuchengetedza mari uye kuchena. Kune zvinhu zvakawanda zvakachipa zviripo zvekushandisa zvakasiyana-siyana. Mabheyaringi epurasitiki anowanzo gadzirwa ne thermoplastic alloys ine fiber matrix uye solid lubricant, iyo ine simba rakanaka uye friction coefficient yakaderera nguva dzose.

3. Chii chinonzi kushanda kwakanaka kwemabheringi epurasitiki? ?

(1) Kuzvizora mafuta pachako

Purasitiki's hunhu hwayo, inozora mabheringi, inoderedza kunonoka kwekutanga uye inochengetedza nzvimbo yakachena. Chikamu chidiki chebheringi chinopfekwa pakutanga uye chinoita basa rekuzora bearing, asi kuchinja kwebheringi pachayo kunogona kuregeredzwa. Izvi zvinoitawo kuti mabheringi epurasitiki anyatsokodzera kushandiswa kwechikafu, nekuti FDA inorambidza kushandiswa kwemafuta mumichina yekugadzira chikafu. Pamusoro pezvo, kunyangwe guruva nezvimwe zvikamu zvichinamatira pamafuta uye zvoita jira revhu, kune mabheringi epurasitiki, chero zvikamu zvinongoiswa mubheringi uye hazvizokanganisi mashandiro.

(2) Kushanda pakupisa kwakaderera uye kwakakwirira

Mabheringi epurasitiki anogona kushanda nguva dzose chero tembiricha iri pakati pe -4° C na260° C uye inogona kutsungirira tembiricha yepamusoro inosvika 600° F. Chigadziko chepurasitiki chinogona kunge chakasimba sechigadziko chesimbi, asi kubereka Madziro matete, kazhinji ane ukobvu hwe 0.0468 "- 0.0625". Madziro matete anopa kupisa kuri nani, zvichikonzera kuti pave nekushanda kwakawanda uye kusakara kushoma. Pamusoro pezvo, madziro matete akareruka uye haawanzo shanduka, zvichiita kuti akwanise kushandiswa nevanhu vane matambudziko ekurema.

(3) Kushanda kwezvakatipoteredza

Nekuda kwehuremu hushoma hwepurasitiki, mabheya epurasitiki anoshandisa mafuta mashoma. Mabheya epurasitiki haadi mamwe machira kana zvimwe zvinowedzerwa kuti abudise mhedzisiro yakafanana nezvikamu zvesimbi zvinowanzowedzerwa nezvinhu zvinokuvadza. Pamusoro pezvo, kugadzirwa kwepurasitiki kunoda mafuta angangoita 10-15% chete zvichienzaniswa nehuwandu hwakaenzana hwearuminiyamu kana simbi.

(4) Kusagona kushandisa makemikari zvakanaka

Mabheya epurasitiki anowanzo dzivirira makemikari nezvinhu zvakasiyana-siyana kupfuura mabheya esimbi, uye anodzivirira kukwenywa nekupfekwa kwemabheya esimbi. Izvi zvinobatsira kuchengetedza coefficient yavo yakaderera yekukweshana uye kufamba zvakanaka pasina kukanganiswa kwakanyanya.

(5) Kugadzirisa pasina kutakura

Sarudza purasitiki yakakodzera zvichienderana nenzvimbo yekushandisa, uye bearing inogona kuramba ngura nekufamba kwenguva. Mushure mekuiswa, bearing yepurasitiki inogara kwenguva refu uye haidi kutsiviwa. Ngura inogona kukonzera kuti mabearing esimbi aome panzvimbo, zvichiita kuti asakwanise kubviswa pasina kuacheka. Mabearing epurasitiki ari nyore kubvisa.

(6) Mutengo wakaderera wepurasitiki

Mapurasitiki mazhinji akachipa pane simbi. Saka mabheringi epurasitiki nemabhushi epurasitiki zvinogona kuderedza mitengo
