Mawonekedwe a kuyimitsidwa kwa polyurethane pamagalimoto

Kufunika kwa m'malo kumasonyezedwa ndi phokoso la creaking pamene mukuyendetsa galimoto. Pogula magawo otsika achi China, vuto limawonekera pakatha miyezi 2-3 yogwira ntchito. 

Kuyimitsidwa kwagalimoto ya polyurethane ndi njira yotsika mtengo kuposa zida za rabara. Imathandizira kugwira ntchito kwa makina mu nyengo yoipa, poyendetsa panjira ndipo imakhala yolimba.

Kodi kuyimitsidwa kwa polyurethane ndi chiyani

Palibe kuyimitsidwa kopangidwa kwathunthu ndi polyurethane (elastomer yopangidwa yokhala ndi katundu wokhazikika). The stabilizer bushing ndi mwakachetechete chipika amapangidwa kuchokera nkhaniyi. Chotsatirachi ndi cholumikizira mbali zina za chassis, chimachepetsa kugwedezeka komanso kugwedezeka uku mukuyendetsa misewu yopingasa.

Zogulitsa za polyurethane ndizoyenera kuyendetsa pamalo osawoneka bwino, osayenda pamsewu, kupitilira mwamphamvu komanso kutembenuka kosalekeza. Zomangamanga zotere zimayikidwa makamaka muzochitika izi:

• kusintha kwa magalimoto amasewera, omwe madalaivala awo amatembenukira mwamphamvu ndikudutsana panjanji;
• kukulitsa kuwongolera kwagalimoto kwa mafani oyendetsa mwaukali;
• kubwezeretsanso kuchepa kwa mtengo pamakina amitundu yakale, yomwe yasokonekera chifukwa chogwira ntchito nthawi yayitali.

Sitikulimbikitsidwa kukhazikitsa zinthu za polyurethane pamagalimoto atsopano, chifukwa pakadali pano chitsimikizo chautumiki chidzathetsedwa.

Polyurethane ndi yopanda mtundu, koma yachikasu, yakuda, lalanje, yofiira, yabuluu imagulitsidwa. Opanga amasakaniza makamaka utoto kusonyeza kuuma.

Zoyenera kwa moyo wautali wautumiki

Zigawo za polyurethane zidzagwira ntchito kwa osachepera 50-100 makilomita zikwizikwi ndi 25-50 km zikwi pamene mukuyendetsa galimoto komanso kuyendetsa galimoto, ngati zinthu zingapo zakwaniritsidwa:

• kuyimitsidwa galimoto kwathunthu kukonzedwanso;
• midadada yopanda phokoso imayikidwa bwino;
• mapiri okhazikika opangidwa ndi mafuta osalowa madzi;
• ntchito ikuchitika pa kutentha osati pansi -40 ° C.

Kuyimitsidwa koyambirira kwa muffler

Ndipo chofunika kwambiri - zigawozo ziyenera kukhala zatsopano komanso kuchokera kwa wopanga wodalirika.

Zochita ndi Zochita

Zigawo za polyurethane zili ndi izi:

• Amasiyana ndi kukana kwamphamvu kwambiri. Zopangira zapamwamba za polyurethane zimatha nthawi yayitali kuposa zopangidwa kuchokera ku mphira wofewa.
• Pangani kuyimitsidwa kukhala zotanuka kwambiri. Galimoto ndiyosavuta kuyendetsa mumsewu woyipa komanso nyengo (ayezi, matalala, mphepo yamphamvu).
• Amalekerera zotsatira za mankhwala, omwe amawaza kwambiri m'misewu m'nyengo yozizira. Mphira umawonongeka msanga mukasakaniza anti-icing.
• Sinthani kasamalidwe kagalimoto. Chifukwa cha kukhalapo kwa mapangidwe a polyurethane mu kuyimitsidwa, zimakhala zosavuta kuti dalaivala aziwongolera galimoto. Imatha kulowa m'makona bwino pa liwiro lalikulu ndipo ndiyosavuta kupitilira ena.
• Amatha pang'onopang'ono kusiyana ndi mankhwala a labala ofewa.
• Oyenera kugwiritsidwa ntchito pa nyengo yoipa. Polyurethane, mosiyana ndi mphira, sichiphwanyidwa ndi kuzizira ndipo sichiuma m'chilimwe chotentha.

Koma zoyipa sizocheperapo kuposa zabwino:

• Opanga magalimoto samayika mbali za polyurethane, kotero simungathe kugula choyambirira. Pali chiwopsezo chachikulu chothamangira muchinyengo chapamwamba.
• Kuyimitsidwa kumakhala zotanuka kwambiri, kotero dalaivala amamva phokoso lililonse poyendetsa misewu yoyipa.
• Mbali za polyurethane zimatha kuphulika pozizira kwambiri (mpaka -40 ° C). Zogulitsa zabwino kwambiri sizingathe kupirira -20 ° C.
• Zimawononga ndalama zambiri kuposa zopangira mphira zoyambirira (koma sizotsika pakuchita).
• Polyurethane imakhudza kwambiri zolimbitsa zitsulo, motero ziyenera kusinthidwa pafupipafupi.

Choyipa china chofunikira ndikuti midadada yopanda phokoso ya polyurethane siyiyenera mtundu uliwonse wagalimoto. Kupaka ndi mankhwala kuyenera kukhala ndi mndandanda wa makina omwe angayikemo.

Komanso, polyurethane sichimamatira bwino kuchitsulo ndipo imatha kuchokapo. Nthawi zambiri, ndichifukwa chake midadada yatsopano yopanda phokoso iyenera kukhazikitsidwa.

Kufunika kwa m'malo kumasonyezedwa ndi phokoso la creaking pamene mukuyendetsa galimoto. Pogula magawo otsika achi China, vuto limawonekera pakatha miyezi 2-3 yogwira ntchito.

Kuyika kwa polyurethane bushings ndi midadada chete kumakhala koyenera ngati kuwonjezereka kwa kayendetsedwe ka galimoto kumawonekera, osati chitonthozo cha dalaivala ndi okwera.

Momwe mungasankhire gawo

Posankha mbali za polyurethane zoyimitsa galimoto, tsatirani malamulo awa:

Werenganinso: Chiwongolero chowongolera damper - cholinga ndi malamulo oyika

• Gulani zojambula kuchokera kwa opanga okhazikika. Iwo ndi apamwamba kwambiri, ngakhale kuti ndi okwera mtengo kuposa zosankha zaku China.
• Osalumikizana ndi ogulitsa omwe amapereka zida zomwe zagwiritsidwa kale ntchito.
• Sankhani gawo m'sitolo kuti muyang'ane ngati ming'alu, zokala, ndi zowonongeka zina.
• Osagula kuchokera kumasamba otsatsa.
• Chida chopanda phokoso chiyenera kugulitsidwa mu phukusi lamphamvu ndi chizindikiro chosonyeza dzina la gawolo, adiresi ndi nambala ya foni ya wopanga, imelo kapena mauthenga ena okhudzana ndi kulankhulana, kutsata miyezo ya GOST.
• Gulani midadada yachete yomwe wopanga amapereka chitsimikizo (nthawi zambiri zaka 1-2, mosasamala kanthu za mtunda).

Onetsetsani kuti muyang'ane pa satifiketi yovomerezeka. Ngati wogulitsa akukana kupereka chikalatacho kuti chiwunikenso, ndiye kuti muli ndi zabodza.

Momwe mungayikitsire kuyimitsidwa kwa polyurethane

Sizingatheke kudziyika paokha magawo opangidwa ndi polyurethane. Kuti muchite izi, mukufunikira chipinda chokhala ndi flyover, dzenje kapena kukweza ndi zipangizo zapadera kuti muwononge kuyimitsidwa. Perekani ntchitoyi kwa ambuye kuchokera ku ntchito zamagalimoto.
