Okweza ma hayidiroliki: zomwe ali komanso chifukwa chake amagogoda

Injini yoyaka yamkati ndi gawo lovuta kwambiri mgalimoto, momwe ntchito yake imagwirira ntchito zimadalira kukonza kwamphamvu kwa chilichonse chomwe chimagwirizana nacho. Chitsanzo cha izi ndi kapangidwe ka makina ogawa mpweya. Amatsegula mavavu olowerera komanso otulutsira pansi pomwe pisitoni yoyenda mu silinda imamaliza kulumikizana kofanana.

Aliyense akudziwa kuti mkati mwa injini yoyaka mkati, ziwalo zake zonse zimatenthedwa. Nthawi yomweyo, zopangidwa ndi chitsulo zimakulitsa. Ndipo pamene galimotoyo ikuyenda, njira zambiri mmenemo zimachitika mu gawo lachigawo chachiwiri. Poterepa, micron iliyonse yamipata imakhala ndi gawo. Valve ikatsegulidwa kale pang'ono kapena pang'ono, izi zimakhudza kwambiri magwiridwe antchito amagetsi.

Pachifukwa ichi, muma motors akale, mipata idayikidwa pakati pa matepi a valavu ndi cam shaft shaft. M'magetsi amakono, njirayi ndiyosavuta momwe ingathere. Kunena zowona, kufunikira kwa izi kwatha, popeza mainjiniya apanga tsatanetsatane monga cholipirira ma hydraulic.

Kodi chimakweza bwanji ma hydraulic

Kuphatikizika kwamadzimadzi kumayikidwa pakati pa tepi yamagetsi ndi kamera ya camshaft. Gawoli limasintha palokha kukula kwa kusiyana kwa matenthedwe. Monga dzinali likusonyezera, kusintha kosinthika kumachitika chifukwa chama hydraulic mafuta pazinthu zolumikizana.

Ngati kale ntchitoyi inkachitika ndi zida zamakina zomwe zimafunikira kusintha kapena kusintha, zinthuzi zimagwira ntchito modzidzimutsa, kupangitsa moyo kukhala wosavuta kwa mwini galimoto.

Zakale za mbiriyakale

Mu injini zakale, mwachitsanzo, zapamwamba zaku Soviet, kunalibe ma hayidiroliki kapena makina okulitsa olumikizira mafinya. Pachifukwa ichi, kukonza kwakanthawi kwa galimotoyo kumaphatikizaponso kusintha kofunikira kwa izi. Opanga nthawi zambiri amakhala ndi nthawi yolowera makilomita 10.

Pamene njirayi idachitidwa, chivundikiro cha valavu chidachotsedwa ndipo phindu la kusiyana kwa matenthedwe lidasinthidwa ndi kafukufuku wapadera ndi kiyi. Sikuti aliyense ali ndi ufulu wochita izi, ndipo ngati izi sizinachitike, injiniyo idayamba kuthamanga mwamphamvu ndikutaya mphamvu zake.

M'makina amenewa, ma valve amayenera kusinthidwa nthawi zonse 40-50, zomwe zimawonjezera mutu kwa eni magalimoto oterowo. Kapangidwe kameneka kamayenera kukonzedwa, kotero makina ochapira makulidwe ena adayamba kukhazikitsidwa pakati pa pusher ndi cam. Tsopano sanali tsinde la valavu lokha lomwe linali likutha, koma gawo ili.

Ngakhale izi, kusintha kunayenera kupangidwabe, ndipo ntchito yokonzanso idachepetsedwa kuti isinthe makina ochapira. Opanga ena amagwiritsabe ntchito magawo ofanana mu injini zawo zamagalimoto.

Ngakhale kusintha kwakukulu pakugwiritsa ntchito njira yogawa gasi, kukonza kwa chipangizocho kumafunikabe kuchitidwa pafupipafupi.

Makina okulitsa amakanika adasinthidwa ndi makina oyambira omwe amakonza mipata yokha. Dongosolo lama hydraulic wokulitsa awonjezera nthawi yayitali yokonza makina oyaka mkati pafupifupi katatu, ndipo tsopano muyenera kuyang'ana pansi pa chivundikiro cha valavu kangapo - osapitilira makilomita 120.

Mulingo wamasika umasankhidwa kotero kuti valavu yomwe ili pamutu wamphamvu imatseguka molingana ndi malo amamera osachita khama. Kuchulukitsa kupanikizika pa tsinde la valavu, kuchuluka kwa mafuta mu sub-piston space kumagwiritsidwa ntchito.

Chifukwa chake, operekera ma hydraulic "amasintha" osati kokha kukulitsa kwamatayala a nthawi, komanso kuvala kwa makamu ndi zimayambira za valavu. Njira yoyambirira yotereyi siyikuphatikiza kusintha kwakanthawi kwa makina osinthirawa.

Mwachidule za momwe hydraulic compensator imagwirira ntchito amafotokozedwa muvidiyoyi:

Opereka ma hayidiroliki. Kodi okwera pama hayidiroliki amagwira ntchito bwanji ndipo chifukwa chiyani amagogoda?

Malo onyamula ma Hydraulic

Kuti mupeze compensator hydraulic mu mota, muyenera kumvetsetsa mawonekedwe a injini. M'magawo amagetsi amakono, mutu uli pamwamba pa silinda, ndipo camshaft imayikidwa mmenemo. Makamera ake amayendetsa ma valve olowera komanso otulutsa.

Ma compensators a Hydraulic, ngati akupezeka mu mtundu wa motayi, adzayikidwa pakati pa cam ndi tsinde la valve. The hydraulic compensator imakhala ndi chilolezo cha valve-to-cam nthawi zonse, mosasamala kanthu za kutentha (ndipo, ndithudi, kufalikira kwa tsinde la valve) kwa ma valve.

Kodi mitundu ndi mitundu iti yama hydraulic compensators

Mfundo ya ntchito imodzi mwa mitundu yolumikizira ikufotokozedwa pamwambapa. Akatswiri opanga kampani iliyonse yamagalimoto amatha kugwiritsa ntchito mitundu ina yamagetsi yonyamula:

• Hydraulic pusher monga tafotokozera pamwambapa. Imaikidwa pakati pa camshaft cam ndi tsinde la valavu;
• Thandizo la Hydro;
• Magalimoto akale amagwiritsidwa ntchito ndi hayidiroliki, yomwe idayikidwa m'miyala yama rocker kapena mu levers of the valve pusher;
• Wodzigudubuza pushers hayidiroliki.

Opanga magalimoto ambiri akuyesera kuti achoke pazowonjezera ma hydraulic, chifukwa zida zama hydraulic pusher ndizosavuta momwe zingathere. Ngakhale chida monga njira yogawa gasi sichingalole kugwiritsa ntchito njira yolumikizirana iyi. Chithunzichi m'munsimu chikuwonetsa malo omwe cholembera ma hydraulic chitha kukhala kutengera mtundu wa injini nthawi.

Ubwino ndi kuipa kwa cholumikizira hayidiroliki

Ma hydraulic lifters ali ndi zabwino zambiri. Izi zikuphatikiza:

• Low phokoso la galimoto;
• Palibenso chifukwa chokonzera kusintha kwa matenthedwe ndi mavavu omwe amayamba chifukwa chovala zachilengedwe;
• Kukonza kwaulere;
• Amapereka kupanikizika kosalekeza kwa tsinde la valavu motsutsana ndi camshaft cam, yomwe imawonetsetsa kuti imagwiranso ntchito bwino ngakhale pamagalimoto owonongeka kwambiri;
• Khola lamphamvu pamakina akale.

Komabe, ngakhale pali zabwino zambiri, ukadaulo wapamwamba uli ndi zovuta zazikulu zingapo:

1. Operekera ma hayidiroliki amagwiritsa ntchito mafuta, ndipo mabowo awo ndi ochepa kwambiri kotero kuti mafuta ochepa sangalowe mkatimo, makamaka ngati dongosololi silinakhale ndi nthawi yotentha. Pachifukwa ichi, mafuta apamwamba ayenera kutsanulira mu injini - nthawi zambiri zopangira. Koma mota yomwe ili ndi mileage yayikulu, m'malo mwake, imafunikira mafuta okutira okhwima - mphete za O zatha kale, motero ma synthetics sangathe kupanga mphero yamafuta apamwamba. Chifukwa cha izi, mphamvu zamagalimoto zikugwa;
2. Ngakhale atagwiritsa ntchito zinthu zina, mafutawo amafunikabe kusinthidwa pafupipafupi, chifukwa pakapita nthawi amataya madzi;
3. Ngati mungalephere, muyenera kugula gawo lomwelo, osati analogi yotsika mtengo (komwe operekera ma hydraulic omwe ali m'malo mwake salola kugwiritsa ntchito mapangidwe ena kupatula omwe amapangidwa ndi wopanga);
4. Popeza kuwonongeka kumachitika pambuyo pake, kukonza kudzakhala kotsika mtengo kuposa kukonza injini yoyaka mkati;

Chosavuta chachikulu ndikofunikira kwa mafuta. Ngati woyendetsa galimoto anyalanyaza zofunikira za parameter iyi, posachedwa akuyenera kufunafuna kugula malo ophatikizira atsopano. Pankhani yamagalimoto omwe apanga gwero lalitali, ma analogs amachitidwe ndi njira yabwino - amaletsa kuvala kwa valavu ndipo nthawi yomweyo amawongolera kusiyana kwa matenthedwe.

Momwe mungasankhire okwera pama hydraulic

Ngati lamba wamagalimoto okhala ndi ma hydraulic lifters, ndiye kuti funso loti mugule zida zatsopano kapena ayi siloyenera - gulani. Kupanda kutero, magawidwe azigawo zamagetsi sizigwira ntchito moyenera - kamera siyitha kutsegula valavu munthawi yake, ndipo mota itaya mphamvu yake.

Ngati sizikudziwika kuti ndi mitundu iti yomwe imayikidwa pagalimoto, ndiye kuti kusaka kwa ma hydraulic lifter kumachitika ndi nambala ya VIN yamagalimoto kapena mtundu wamagalimoto omwe ali m'ndandanda. Ndikofunikira kudziwa kuti ogulitsa ena amatcha njira iliyonse yokulumikizira mafupa. Mukamasankha gawo, mutha kuwuzanso wogulitsa mtundu wamagalimoto (SOHC kapena DOHC - werengani za kusiyana pakati pazosinthazi apa).

Mukamasankha bajeti kapena cholipirira choyambirira, muyeneranso kulabadira mawonekedwe ake - kulemera, masika, ndi zina zambiri. (ngati zalembedwa m'ndandanda). Ngati mavavu ali ndi sitiroko yaying'ono, ndiye kuti mapangidwe owonjezera opepuka amatha kukhazikitsidwa.

Omwe amanyamula ma hydraulic ali bwino

Posankha gawo ili, muyenera kukumbukira: bajeti yofananira nthawi zambiri imafuna kusinthidwa. Koma ngakhale pakati pazomwe zimatchedwa zida zoyambira zoyambirira, zimapezeka zabodza. Kuti musawononge ndalama pazinthu zotsika mtengo, samverani opanga omwe adziwonetsa okha pamsika wamagalimoto.

Onaninso kuti opanga magalimoto enieniwo samapanga zophatikizira zama hydraulic. Amagwiritsa ntchito ntchito zamakampani payokha, chifukwa chake gawo ili kulibe kuchokera kwa opanga - amagulidwa kumakampani odziyimira pawokha ndipo amagulitsidwa ngati choyambirira, koma pamtengo wokwera.

Mutha kuyimitsa kusankha kwanu kwa opanga awa:

• Wopanga waku Germany INA. Opereka ma hayidiroliki ndiabwino kwambiri ndipo samalephera nthawi yake isanakwane;
• Kampani ina yaku Germany ya Febi, koma mtundu wazogulitsa zawo ndiwotsikirako pang'ono poyerekeza ndi woimira wakale. Dziko lopanga likuwonetsedwa pakapangidwe ka gawolo - muyenera kulabadira izi, popeza mafakitale aku China samapanga zinthu za premium nthawi zonse;
• SWAG ndi kampani yomwe ntchito zake zimagwiritsidwa ntchito ndi omwe amapanga gulu la VAG (za mtundu wamagalimoto omwe akuphatikizidwa ndi nkhawa, adauza kale pang'ono). Zigawo za kampaniyi zili mgulu la bajeti, koma zabodza ndizofala kwambiri;
• Pansipa pamindandanda pali opangira ma hydraulic opangira ma AE kapena Ajusa. Zotsatira za mtengo wotsika ndizogwirira ntchito zochepa (pafupifupi 10 mileage). Vuto lina ndikofunikira kwambiri pamtundu wamafuta.

Kuzindikira ndikusintha kwa ma hydraulic lifters

Kulephera kwa ma hydraulic lifters kumapezeka powagogoda. Phonendoscope imagwiritsidwa ntchito kuwonetsetsa kuti mawuwo amachokera kwa omwe amapereka.

Ngati kusakhazikika kwa oyendetsa ma hydraulic kumakhazikitsidwa, ndiye kuti amachotsedwa ndi maginito, koma izi zimachitika ngati nthawi yoyera komanso yothandiza. Izi zimachitika kuti gawolo limangokhala pampando, ndichifukwa chake kudula kumayenera kuchitika ndi chopopera chapadera.

Pali njira zingapo zowunika momwe magudumu anyamula amagwirira ntchito. Choyamba, kuwunika kwakunja kwa gawolo kumachitika kuti apeze zolakwika. Malo ogwirira ntchito a elementi adzawoneka ndi maso. Chachiwiri, pali zolumikizira zomwe sizingatheke. Poterepa, mutha kuyang'anira magawo amkati kuti mudziwe kuchuluka kwa kuvala.

Njira ina yodziwitsira - mafuta amathiridwa mu cholumikizira chomaliza. Gawo logwira ntchito silingafinyidwe ndi zala zanu. Kupanda kutero, iyenera kusinthidwa.

Chifukwa chiyani ma hydraulic lifters amagogoda

Kuwomba kwa okwera pama hydraulic kumatha kuwonedwa ngakhale mgalimoto zatsopano, chifukwa izi sizomwe zimakhala chizindikiro cha kuwonongeka kwina. Zotsatirazi zitha kuwonedwa ponseponse pama injini oyaka moto amkati komanso pagawo lamagetsi lomwe lafika kale pantchito yotentha. Ngakhale izi zichitike, phokosoli siliyenera kunyalanyazidwa, chifukwa kusokonekera kumeneku kudzakhudza magwiridwe antchito a gasi.

Ganizirani zomwe zimayambitsa kugogoda okwera pama hydraulic m'malo osiyanasiyana a injini.

Zifukwa zogogoda kwa hydraulic compensator "zotentha" (injini ikatenthedwa):

Izi zimachitika pagalimoto yotentha chifukwa cha:

1. Mafuta oyipa a injini, kapena sanasinthe kwanthawi yayitali;
2. Fyuluta yakuda yamafuta - chifukwa cha iyo, mafuta samafika pama hydraulic lifters atapanikizika;
