Kugwiritsa Ntchito Zida za Nylon mu Automobile Engine

Magawo amagalimoto ndi gawo lofunikira komanso lomwe likukula mwachangu pakugwiritsa ntchito zida za nayiloni. Nayiloni ili ndi katundu wabwino kwambiri wokwanira, yosavuta kupanga komanso yocheperako, motero yagwiritsidwa ntchito bwino pakukulitsa nkhungu ndi kusonkhanitsa.

Ziwalo mkati mwa injini dera la galimoto ayenera kupirira chikoka kwa nthawi yaitali otentha ndi ozizira chilengedwe. Muyezo wanthawi zonse ndi woti magawowo amayenera kupirira kutentha kwa -40 ~ 150 ° C. Muyezo uwu ukhoza kukwaniritsa malo omwe amagwiritsidwa ntchito posinthana kutentha ndi kuzizira chaka chonse; Komanso, injini Mbali m'derali ayeneranso kupirira mphamvu ya chipale chofewa wothandizila kashiamu mankhwala enaake, antifreeze yaitali, mafuta osiyanasiyana ndi zouluka mchenga.

1. Fyuluta yamafuta 

Pambuyo m'malo zitsulo ndi galasi CHIKWANGWANI analimbitsa nayiloni zakuthupi, kumtunda ndi gawo lapakati pa chitoliro zitsulo motero jekeseni kuumbidwa ndi P.A6+10% GFpulasitiki yosinthidwa, ndi zitsulo zosefera mauna ndi gawo lapakati zimalumikizidwa pamodzi.

KugwiritsaPA6+10% GFzinthu zosinthidwa jekeseni mafuta fyuluta akhoza kuchepetsa mpweya kusakaniza mlingo ndi 10% -30% mfundo, mtengo wonse akhoza kuchepetsedwa ndi 50%, ndi okwana chigawo kulemera akhoza kuchepetsedwa ndi 70%.

2. Chophimba cha injini

Pofuna kukwaniritsa cholinga chochepetsera phokoso komanso kukonza chitonthozo cha kukwera pamene mukugwiritsa ntchito galimotoyo, mbale yophimba yopangidwa ndi galasi lopangidwa ndi magalasi opangidwa ndi nayiloni yokhala ndi ntchito yotchinga phokoso imagwiritsidwa ntchito pa injini. Pali zida zotchingira mawu.

Zovala za injini zimafunikira zida zomwe zili ndi: kulimba kwambiri komanso kulimba, masamba ocheperako, mawonekedwe apamwamba, kuchuluka kwamadzimadzi, komanso kuwongolera mwachangu.

Chivundikiro cha injini

3. Radiator

Radiator ndi chipangizo chozizira m'galimoto chomwe chimachepetsa kutentha kwa injini kuchokera kutentha kwambiri mpaka kutentha kochepa. Chipinda chapakati, kagawo kakang'ono, kagawo kakang'ono, tsamba la fan ndi chivundikiro chachitetezo cha masamba amapangidwaPA6+GF or PA66+GFzakuthupi.

4. Zopangira zolowetsa ndi kukhetsa

Chitoliro cholumikizira pa polowera cha choziziritsa chanthawi yayitali cha injini chikhoza kulimbikitsidwa ndiPA6+GF or PA66+GF.Zida zopangira mapaipi otulutsa potulutsa choziziritsa kukhosi kwa nthawi yayitali zimakhala ndi zofunika kwambiri pakukana kutentha, ndipo zimafunika kupirira kutentha kwambiri kwa 230 ° C. Iyenera kusankha zida zolimbikitsira zosagwira kutentha, mongaPA46+GF.

5. Chophimba chamutu cha silinda

Chivundikiro chamutu cha cylinder ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pazinthu za nayiloni m'magalimoto, chachiwiri pakugwiritsira ntchito kambirimbiri.

Cholinga chachikulu cha kusonkhanitsa mankhwalawa ndi kuchepetsa phokoso. Chigawo ichi ndi gawo loyamba lofunikira pakuchepetsa phokoso m'dera la injini. Izi zimagwiritsa ntchitoPA66+GF ndi PA66+MFzida zosinthidwa.

6. Kudya mochuluka

Kuchuluka kwa madyedwe kumapangidwa makamaka ndiPA6+GFzida zosinthidwa, zomwe ndi gawo lalikulu kwambiri la zida za nayiloni. Tsopano opanga magalimoto onse amagwiritsa ntchito kuchuluka kwa nayiloni.

Zomwe zimapangidwira zopangidwa ndi zinthu zosinthidwa za nayiloni zimakhala ndi ubwino wolemera pang'ono, mtengo wotsika, wosalala wochuluka pamwamba, zabwino kwambiri zotetezera kutentha, zimatha kusintha injini, kuchepetsa phokoso, kutsika mtengo kwa zipangizo zopangira, komanso kukhala opindulitsa pachitetezo cha chilengedwe.
