Makina Makina Ogula Chidwi (1)

Zowopsa zisanu zazikulu za kutentha kwambiri kukwera kwa makina jekeseni akamaumba ndi: matenthedwe matenthedwe makina, kuchepetsa kukhuthala kwa mafuta, kusinthika kwa zisindikizo za mphira, Kuchuluka kwa mafuta oxidation ndi kuwonongeka, ndi kuchepetsa mphamvu ya chigawo cha mpweya.
Chimodzi mwa zoopsa: matenthedwe matenthedwe makina
Zigawo zosuntha zokhala ndi ma coefficients osiyanasiyana akukula kwamafuta m'zigawo za hydraulic zimakakamira chifukwa cha mipata yawo yaying'ono yokwanira., kuchititsa malfunctions, kukhudza kulondola kwa kufalikira kwa ma hydraulic system, ndi kuwonongeka kwa magwiridwe antchito a magawo.
Kuwononga ziwiri: kuchepetsa mamasukidwe akayendedwe a mafuta
Kutentha kwambiri kwa makina omangira jekeseni kumapangitsa kuti kukhuthala kwamafuta kuchepe, onjezerani kutayikira, ndi mphamvu ya volumetric ya mpope ndi mphamvu ya dongosolo lonse zidzachepetsedwa kwambiri. Pamene mamasukidwe akayendedwe a mafuta amachepetsa, filimu yamafuta ya valve yotsetsereka ndi mbali zina zosuntha zimakhala zowonda komanso zodulidwa, ndipo kukana kukangana kumawonjezeka, kumabweretsa kuchuluka kwa mavalidwe.
Zowopsa 3: Kusintha kwa zisindikizo za rabara
Kutentha kwakukulu kwa makina opangira jekeseni kumasokoneza zisindikizo za rabara, onjezerani kulephera kwa ukalamba, kuchepetsa ntchito yosindikiza ndi moyo wautumiki, ndi kuyambitsa kutayikira.
Zowopsa 4: Imathandizira makutidwe ndi okosijeni komanso kuwonongeka kwa mafuta
Kutentha kwakukulu kwa makina omangira jekeseni kumafulumizitsa makutidwe ndi okosijeni ndi kuwonongeka kwa mafuta., kutulutsa zinthu za bituminous, ndikuchepetsa moyo wautumiki wamafuta a hydraulic. Madziwo amalepheretsa kutuluka kwa madzi ndi khomo la valve, kupangitsa kuti valavu yopondereza ikakamire ndikulephera kusuntha, ndipo chitoliro chachitsulo chatambasulidwa ndi kupindika, kapena ngakhale kusweka.
Zowopsa 5: Kupangitsa kuti pakhale kusagwira bwino ntchito kwa zigawo
Kutentha kwakukulu kwa makina omangira jekeseni kumapangitsa kuti magawowo awonongeke. Mpweya wosungunuka m'mafuta udzathawa, kumabweretsa matumba a mpweya, zomwe zidzachepetsa magwiridwe antchito a hydraulic system. Kutentha koyenera kogwira ntchito kwa hydraulic system kuyenera kukhala pakati 45 madigiri ndi 50 madigiri. Chifukwa chake ndikuti ma hydraulic system amapangidwa molingana ndi kukakamizidwa kosankhidwa kwamafuta viscosity.Koma mamasukidwe akayendedwe adzasintha ndi kutentha kwamafuta, zomwe zidzakhudza ntchito mu dongosolo. Zigawo, monga masilinda amafuta, ma hydraulic valves, etc., kuchepetsa kulondola kwa kuwongolera ndi kukhudzidwa kwa mayankho, makamaka makina ojambulira olondola. Nthawi yomweyo, ngati kutentha kuli kwakukulu, idzafulumizitsa kukalamba kwa chisindikizo ndikupangitsa kuti ikhale yolimba komanso yosweka.Ngati kutentha kuli kochepa kwambiri., mphamvu yogwiritsira ntchito idzagwiritsidwa ntchito ndipo liwiro la ntchito lidzachepetsedwa. Chifukwa chake, m'pofunika kumvetsera kwambiri kutentha kwa hydraulic mafuta. Pali zifukwa zambiri za kutentha kwa mafuta, koma ambiri a iwo ndi chifukwa cha kulephera kwa kayendedwe ka mafuta kapena kulephera kwa dongosolo lozizira.

Mtundu ndi kuchuluka kwa mapulasitiki omwe amagwiritsidwa ntchito (zopangira imodzi kapena mapulasitiki angapo);
Kukula kwa mawonekedwe (kutalika, m'lifupi, kutalika, makulidwe), kulemera, etc.. mankhwala opangidwa ndi jakisoni; amafuna akamaumba, monga zikhalidwe zabwino, liwiro kupanga, etc..

Pambuyo kupeza zambiri pamwamba, mukhoza kutsatira njira pansipa kusankha abwino makina jekeseni akamaumba:
1. Sankhani mtundu woyenera: Mtundu ndi mndandanda zimatsimikizika ndi malonda ndi pulasitiki.
Popeza pali mitundu yambiri ya makina opangira jekeseni, Ndikofunikira kudziwa kuti ndi makina ati a jekeseni kapena mndandanda wazomwe ziyenera kupangidwa kuyambira koyambirira, monga ma thermoplastics wamba kapena zopangira za bakelite kapena zopangira PET. Mtundu, mitundu iwiri, mitundu yambiri, interlayer kapena mtundu wosakanikirana, etc.. Kuphatikiza apo, mankhwala ena amafuna zinthu monga bata mkulu (kutseka kotsekedwa), mwandondomeko kwambiri, liwiro lowombera kwambiri, kuthamanga kwakukulu, kapena kupanga mwachangu (Mipikisano kuzungulira), ndi mndandanda woyenera ayeneranso kusankhidwa kupanga.
Ikhoza kuikidwa pansi: Sankhani ngati “Chigawo Chachikulu Chamkati”, “Makulidwe a nkhungu”, “Nkhungu Yochepa Kukula” ndipo “Die Plate Size” makina ali oyenera malinga ndi kukula kwa nkhungu kutsimikizira ngati nkhungu ikhoza kuyikidwa pansi.
M'lifupi ndi kutalika kwa nkhungu ziyenera kukhala zazing'ono kuposa kapena mbali imodzi yaying'ono kuposa mtunda wamkati wa ndime yayikulu.;
M'lifupi ndi kutalika kwa nkhungu ziyenera kukhala mkati mwa kukula kwa mbale ya nkhungu;
Makulidwe a nkhungu ayenera kukhala pakati pa makulidwe a nkhungu a makina opangira jekeseni;
M'lifupi ndi kutalika kwa nkhungu ziyenera kukumana ndi kukula kwa nkhungu komwe kumalimbikitsidwa ndi makina opangira jekeseni, ndipo sichingagwire ntchito ngati chiri chochepa kwambiri;
3. Pezani: The nkhungu ndi yomalizidwa mankhwala kudziwa ngati “nkhungu kutsegula sitiroko” ndipo “matenda a nkhungu” ndizokwanira kutulutsa chomaliza.
Kutsegula kwa nkhungu kuyenera kukhala kosachepera kuwirikiza kawiri kutalika kwa chinthu chomalizidwa potsegula ndi kutseka nkhungu., ndi kutalika kwa sprue kuyenera kuphatikizidwa;
Kugunda kwa nkhungu yothandizira kuyenera kukhala kokwanira kutulutsa chomaliza;
4. Zotseka: Kuchuluka kwa “clamping mphamvu” anatsimikiza ndi mankhwala ndi pulasitiki.
Zipangizo zikagwiritsidwa jekeseni wa nkhungu mopanikizika kwambiri, amapanga mphamvu yothandizira nkhungu. Chifukwa chake, Clamping wa makina jekeseni akamaumba ayenera kupereka zokwanira “clamping mphamvu” kuteteza nkhungu kuti isatsegulidwe. Kuwerengera kwa kufunikira kwa clamping force ndi motere:
Werengetsani malo omwe akuyembekezeka kwa chinthu chomalizidwa molunjika ku nkhungu yosinthira kuchokera pakuwoneka kukula kwa chinthu chomalizidwa;
Die support force = malo omwe akuyembekezeredwa omwe amalizidwa molunjika ku nkhungu yosinthira (cm2) × chiwerengero cha mphako nkhungu × kuthamanga mu nkhungu (makilogalamu / cm2);
Kupanikizika mu nkhungu kumasiyanasiyana ndi zipangizo, zambiri 350 ~ 400kg/cm2 kwa zipangizo;
Mphamvu yothina ya makinawo iyenera kukhala yayikulu kuposa mphamvu yothina, ndi chifukwa cha chitetezo, clamping mphamvu ya makina nthawi zambiri 1.17 nthawi zambiri kuposa mphamvu yothirira;
Panthawi ino, zofotokozera za clamping unit zidatsimikiziridwa poyambirira, ndipo tonnage ya chitsanzo yatsimikiziridwa pafupifupi, ndiyeno masitepe otsatirawa akuyenera kuchitidwa kuti atsimikizire kuti ndi jekeseni yanji yomwe ili ndi screw diameter yomwe imakwaniritsa zofunikira.
5. Jakisoni wathunthu: Dziwani zofunikira “kuchuluka kwa jakisoni” kuchokera kulemera kwa zomwe zatsirizidwa ndi kuchuluka kwa zikopa za nkhungu ndikusankha koyenera “wononga awiri”.
Kuwerengera kulemera kwa mankhwala omalizidwa, kuchuluka kwa zibowo za nkhungu (nkhungu imodzi ndi mabowo angapo) adzaganiziridwa;
Chifukwa chokhazikika, kuchuluka kwa jekeseni kumafunika kupitirira 1.35 nthawi zolemera za mankhwala omalizidwa, ndiye, kulemera kwa mankhwala omalizidwa kumayenera kukhala mkati 75% voliyumu ya jekeseni;
6. Jekeseni wabwino: Zinthu monga “kagwere psinjika chiŵerengero” ndipo “kuthamanga kwa jakisoni” zimatsimikiziridwa ndi pulasitiki. Mapulasitiki ena amisiri amafuna kuthamanga kwambiri kwa jekeseni ndi mapangidwe oyenera a kukomoka kuti akhale ndi zotsatira zabwino pakuumba. Chifukwa chake, kuti mankhwala omalizidwa awombedwe bwino, zosowa za kupanikizika kwa jakisoni ndi kuchuluka kwa psinjika ziyenera kuganiziridwanso posankha kagwere. .
Nthawi zambiri, wononga ndi awiri ang'onoang'ono angapereke apamwamba jekeseni kuthamanga.
7. Ponyani mwachangu: ndi kutsimikizira “liwiro lakuwombera”.
Zogulitsa zina zimafunikira jakisoni wokwera kwambiri komanso jakisoni wofulumira kuti apange kuumba kokhazikika, monga zinthu zowonda kwambiri. Pamenepa, kungakhale kofunikira kutsimikizira ngati kuchuluka kwa jakisoni ndi kuchuluka kwa jakisoni wa makina ndikokwanira, komanso ngati iyenera kukhala ndi zida zowonjezera, zotseka zotseka ndi zida zina. Nthawi zambiri, momwemonso, wononga yomwe ingapereke kuthamanga kwapamwamba kwa jekeseni nthawi zambiri imakhala ndi liwiro lotsika lowombera, m'malo mwake, wononga zomwe zingapereke kuthamanga kwapansi kuwombera nthawi zambiri zimakhala ndi liwiro lapamwamba. Chifukwa chake, posankha m'mimba mwake wononga, voliyumu ya jekeseni, jekeseni kuthamanga ndi mlingo jekeseni (liwiro la jakisoni) ziyenera kuwerengedwa pamtanda ndikusankhidwa.
Kuphatikiza apo, kapangidwe ka zingwe zingapo kangagwiritsidwenso ntchito kufupikitsa nthawi youmba ndi zochitika zofananira.
