Kodi maubwino a mchere akuponya ma bedi lotani?
Michere ya mchere (yopangidwa ndi anthu yopanga manrein konkriti) yalandilidwa kwambiri pamakina ogulitsa makina oposa 30 monga zinthu zochitira umboni.
Malinga ndi ziwerengero, ku Europe, imodzi mwa zida 10 zilizonse zimagwiritsa ntchito michere ya mchere ngati kama. Komabe, kugwiritsa ntchito zokumana nazo zosayenera, chidziwitso chosakwanira kapena cholakwika chimatha kukayikira komanso tsankho. Chifukwa chake, popanga zida zatsopano, ndikofunikira kupenda maubwino ndi zovuta zopukutira mchere ndikuwafanizira ndi zinthu zina.
Makina omangira kumanga nthawi zambiri amagawika chitsulo, kuponya michere (polymer ndi / kapena mawonekedwe ang'onoang'ono (oyenda / osakhalapo) ndi mwala wachilengedwe (monga mwala wachilengedwe). Nkhani iliyonse ili ndi mawonekedwe ake, ndipo palibe zinthu zabwino. Pokhapokha popenda zabwino ndi zovuta za nkhaniyi malinga ndi zomwe zikufunika, zomwe zingasankhidwe.
The two important functions of structural materials—guarantee the geometry, position and energy absorption of components, respectively put forward performance requirements (static, dynamic and thermal performance), functional/structural requirements (accuracy, weight, wall thickness, ease of guide rails) for materials installation, media circulation system, logistics) and cost requirements (price, quantity, availability, system characteristics).
I. Zofunikira za magwiridwe antchito
1. Makhalidwe okhazikika
Chizindikiro chokwanira chokhazikika cha maziko nthawi zambiri chimakhala chowuma chochepa kwambiri pansi pa zolekanitsa, osati mphamvu zambiri. Kwa kuphatikizika kwa zitsulo zotsekemera, kuponyera michere kumaganiziridwa kuti ndi zinthu za Isotropic hootogemeneous zinthu zomvera Hooke.
Kuchulukitsa ndi zotanuka za kuponyera mchere za mchere ndizaziyamodzi 1/3 za zoponyera chitsulo. Popeza kuponyera michere ya mchere ndikuyika zitsulo zimakhala ndi kuuma komweko, pansi pa kulemera kofanana, kulimba kwa michere ndi michere kwa mchere ndizofanana popanda kuganizira za mawonekedwe. Nthawi zambiri, makulidwe opangidwa ndi michere nthawi zambiri amakhala atatu omwe amataya zitsulo, ndipo izi sizingapangitse mavuto pazinthu zamakina za malonda kapena kuponyera. Kufuula kwamchere ndikoyenera kugwira ntchito m'malo okhazikika omwe amanyamula zigawo (mabedi, zithandizo, kapena matebulo ang'onoang'ono (mwachitsanzo, zosintha zida). Kulemera kwa zigawo kumachepera ndi zida zopangira mchere opanga, ndipo zinthu zoponya michere zopingasa pamwamba 15 zimakhala zosowa.
2. Makhalidwe Amphamvu
Kuthamanga kwakukulu ndi / kapena kupitilizidwa kwa shaft, ndikofunikira kwambiri momwe magwiridwe antchito amathandizira. Kusuntha mwachangu, chida chosinthidwa mwachangu, komanso kudyetsa kwambiri-kuthamanga kwambiri kumalimbitsa mosalekeza masinthidwe a makina. Kuphatikiza pa mawonekedwe a chigawocho, kusokonekera, kugawa kwakukulu, ndi kuuma kwazinthu zomwe zimakhudzidwa kwambiri ndi zomwe zingawonongeke.
Kugwiritsa ntchito michere kumapereka njira yabwino yothetsera mavutowa. Chifukwa imatenga kugwedezeka nthawi 10 kuposa zikhalidwe zachikhalidwe, zimatha kuchepetsa matalikidwe ndi chilengedwe.
Pogwiritsa ntchito magwiridwe antchito monga makina, zimatha kubweretsa kuwongolera kwambiri, kukhala bwino kwambiri, komanso moyo wa chidalile. Nthawi yomweyo, malinga ndi phokoso, kupondaponda micherenso kudzera mu fanizo ndi kutsimikizika kwa zitsulo, kufalitsa mafayilo ndi zinthu zosiyanasiyana ma injini osiyanasiyana ndi ma center. Malinga ndi kusanthula momveka bwino, kupondereza kwamchere kumatha kuchepetsedwa kwa 20% pakukakamizidwa.
3. Katundu wa mafuta
Akatswiri akuyerekeza kuti pafupifupi 80% ya zopakidwa pamakina zimayambitsidwa ndi zotsatira za mafuta. Njira zosokoneza monga matenthedwe amkati kapena kunja kutsatsa, kusintha magwiridwe antchito, etc. zonse zimayambitsa kuphatikizika kwa mafuta. Kuti athe kusankha bwino kwambiri, ndikofunikira kufotokozera zofunikira zakuthupi. Kutentha kwambiri komanso kutentha kochepa kumapangitsa kuponyeziritsa michere kuti mukhale ndi mankhwala othandizira kutentha kwa kutentha kwa kutentha kwa kutentha (monga kusintha kozungulira) kusinthasintha) kusinthasinthasintha. Ngati kutsatsa msanga kumafunikira ngati bebe lachitsulo kapena kutentha kwa bedi sikuletsedwa, kutentha kapena zida zozizira kumatha kuponyedwa mwachindunji mu mchere woponyera kutentha. Kugwiritsa ntchito mtundu wamtunduwu wolipiritsa kumatha kuchepetsa kuwonongeka komwe kumachitika chifukwa cha kutentha kwa kutentha, komwe kumathandizira kukonza kulondola kwa mtengo woyenera.
Ii. Zofunikira ndi Zofunikira
Umphumphu ndi chinthu chodziwika bwino chomwe chimasiyanitsa michere ya michere kuchokera kuzinthu zina. Kutentha kwakukulu kwa michere kutukuza michere ndi 45 ° C, komanso zoumba zambiri komanso zojambula, zigawo ndi michere zimaponyedwa pamodzi.
Njira zapamwamba zobwereza zobwezeretseranso zitha kugwiritsidwanso ntchito pa michere yam'madzi, zomwe zimapangitsa kuti zikhale zolondola komanso zapamwamba zomwe sizikufuna makina. Monga zida zina zapansi, kuponyera macheredwe amchere kumayang'aniridwa ndi malamulo apadera opangidwa. Makulidwe a khoma, zowonjezera zonyamula katundu, nthiti zonyamula, zotsitsa ndi zotsitsa ndi njira zonse ndizosiyana ndi zinthu zina pamlingo wina, ndipo zimayenera kulingaliridwa pasadakhale pakupanga.
Iii. Zofunikira
Ngakhale kuli kofunikira kulingalira kuchokera ku malingaliro aukadaulo, kuchita bwino kukuwonetsa kufunika kwake. Kugwiritsa ntchito michere ya mchere kumathandiza kuti mainjiniya asunge zochulukirapo komanso ndalama zothandiza. Kuphatikiza pa kupulumutsa ndalama zolipirira, kuponyera, msonkhano womaliza, ndipo kuchuluka kwa zinthu zowonjezera (zonyamula ndi mayendedwe) zonse zimachepetsedwa. Poganizira za ntchito yayikulu kwambiri ya michere, iyenera kuwonedwa ngati polojekiti yonse. M'malo mwake, zimakhala zomveka kupanga njira yofanizira mtengo pomwe maziko adayikidwa kapena kukhazikitsidwa. Mtengo wokwera kwambiri ndi mtengo wa michere ndikuwongolera, koma mtengo wake ukhoza kuchepetsedwa kugwiritsa ntchito (500-1000 zidutswa / chitsulo), ndipo pachaka chizidutswa cha pachaka cha 10-15.
Iv. Kuchuluka kwa ntchito
Monga mabungwe amiyala, kuponyera michere nthawi zonse kumabwezeretsa zinthu zachilengedwe, ndi chinsinsi cha kuuka kwake mwachangu kumagona, nkhungu, ndi nyumba yolumikizira. Pakadali pano, michere ya mchere imagwiritsidwa ntchito kwambiri pamakina ambiri amakina monga zokuza ndi makina othamanga kwambiri. Opanga makina amapanga apainiya mu chipangizo cha Chida chogwiritsa ntchito michere michere pamabedi a makina. Mwachitsanzo, makampani otchuka padziko lonse lapansi monga ABA Z & B, Bahmler, Mikshad, Scaudt, Stude, Slaven of Stremtures kuti adziwe zambiri.
Ndi katundu wowonjezereka wa Mphamvu wa Mphamvu, kuponyedwa m'matumbo a mchere kumayamizidwanso ndi makampani otsogola padziko lonse lapansi omwe ali m'munda wa zogulidwa. Bedi lopsinjika mineral lili ndi chifukwa chabwino kwambiri ndipo mutha kuthetsa mphamvu yomwe imapangidwira ndi matalala a mzere. Nthawi yomweyo, kuphatikiza kwachilengedwe kumayamwa zabwino zolimbitsa thupi ndi zomangamanga kumatha kukonza bwino ntchito yogwira ntchitoyo ndi moyo wautumiki wa gudumu lanji.
