Kodi mungasankhe bwanji chingwe cholimba choyenera?

Zingwe zokwera zingagawidwe m'zingwe zosinthasintha ndi zingwe zosasunthika. Chingwe chosinthasintha chimakhala ndi mphamvu yosinthasintha kotero kuti pakagwa nthawi, chingwecho chikhoza kutambasulidwa pang'onopang'ono kuti chichepetse kuwonongeka komwe kumachitika chifukwa cha kugwa mwachangu kwa wokwera.

Pali njira zitatu zomwe chingwe chosinthasintha chimagwiritsidwa ntchito: chingwe chimodzi, chingwe cha theka, ndi chingwe chachiwiri. Zingwe zomwe zimagwirizana ndi njira zosiyanasiyana zimasiyana. Chingwe chimodzi ndi chomwe chimagwiritsidwa ntchito kwambiri chifukwa kugwiritsa ntchito kwake n'kosavuta komanso kosavuta kugwiritsa ntchito; Chingwe cha theka, chomwe chimadziwikanso kuti chingwe chachiwiri, chimagwiritsa ntchito zingwe ziwiri kuti zimangidwe pamalo oyamba oteteza nthawi imodzi pokwera, kenako zingwe ziwirizo zimamangidwa m'malo osiyanasiyana oteteza kuti njira ya chingwe isinthidwe mwanzeru ndipo kukangana kwa chingwe kuchepe, komanso chitetezo chowonjezereka chifukwa pali zingwe ziwiri zotetezera wokwera. Komabe, sizigwiritsidwa ntchito kawirikawiri pokwera mapiri, chifukwa njira yogwirira ntchito ya chingwe chamtunduwu ndi yovuta, ndipo okwera ambiri amagwiritsa ntchito njira yoponyera ndi kupachika mwachangu, zomwe zingasinthe bwino njira ya chingwe chimodzi;
Chingwe chachiwiri chimapangidwa kuti chiphatikize zingwe ziwiri zopyapyala kukhala chimodzi, kuti chiteteze ngozi ya chingwe kudulidwa ndikugwa. Kawirikawiri, zingwe ziwiri za mtundu womwewo, chitsanzo, ndi gulu zimagwiritsidwa ntchito pokwera zingwe; Zingwe zokhala ndi mainchesi akuluakulu zimakhala ndi mphamvu yabwino yonyamula, kukana kukwawa, komanso kulimba, komanso zimakhala zolemera. Pa kukwera chingwe chimodzi, zingwe zokhala ndi mainchesi a 10.5-11mm ndizoyenera kuchita zinthu zomwe zimafuna kukana kuwonongeka kwambiri, monga kukwera makoma akuluakulu a miyala, kupanga mapangidwe a chisanu, ndi kupulumutsa, nthawi zambiri pa 70-80 g/m. 9.5-10.5mm ndi makulidwe apakati omwe amagwiritsidwa ntchito bwino kwambiri, nthawi zambiri 60-70 g/m. Chingwe cha 9-9.5mm ndi choyenera kukwera mopepuka kapena kukwera mwachangu, nthawi zambiri pa 50-60 g/m. M'mimba mwake wa chingwe chomwe chimagwiritsidwa ntchito pokwera theka la chingwe ndi 8-9mm, nthawi zambiri 40-50 g/m yokha. M'mimba mwake wa chingwe chomwe chimagwiritsidwa ntchito pokwera zingwe ndi pafupifupi 8mm, nthawi zambiri 30-45g/m yokha.

Zotsatira
Mphamvu yokhudza chingwe ndi chizindikiro cha momwe chingwe chimagwirira ntchito, zomwe zimathandiza kwambiri kwa okwera mapiri. Mphamvu yotsika ikakhala yokwanira, chingwe chimagwirira ntchito bwino, zomwe zingateteze bwino okwera mapiri. Nthawi zambiri, mphamvu yokhudza chingwe imakhala pansi pa 10KN.

Njira yeniyeni yoyezera mphamvu yogwira ntchito ndi iyi: chingwe chomwe chimagwiritsidwa ntchito koyamba chimagwa chikalemera makilogalamu 80 (makilogalamu) ndipo chinthu chogwera (Factor Yogwera) ndi 2, ndipo mphamvu yayikulu yomwe chingwecho chimagwira. Pakati pawo, coefficient yogwera = mtunda woyima wa kugwa / kutalika kwa chingwe kogwira ntchito.

Chithandizo chosalowa madzi
Chingwe chikanyowa, kulemera kwake kudzawonjezeka, kuchuluka kwa mathithi kudzachepa, ndipo chingwe chonyowa chidzazizira kutentha kochepa ndipo chidzasanduka ngati popsicle. Chifukwa chake, pokwera pamwamba, ndikofunikira kwambiri kugwiritsa ntchito zingwe zosalowa madzi pokwera ayezi.

Chiwerengero chachikulu cha kugwa
Chiwerengero chachikulu cha kugwa kwa chingwe ndi chizindikiro cha mphamvu ya chingwe. Pa chingwe chimodzi, chiwerengero chachikulu cha kugwa chimatanthauza chiŵerengero cha kugwa cha 1.78, ndipo kulemera kwa chinthu chogwa ndi 80 kg; Pa theka la chingwe, kulemera kwa chinthu chogwa ndi 55 kg, ndipo zinthu zina sizisintha. Kawirikawiri, chiwerengero chachikulu cha kugwa kwa chingwe ndi nthawi 6-30.

Kukulitsa
Kupindika kwa chingwe kumagawidwa m'magulu awiri: kupindika kwa chingwe ndi kupindika kwa chingwe. Kupindika kwa chingwe kumayimira kuchuluka kwa chingwe chotambasula pamene chingwe chili ndi kulemera kwa makilogalamu 80 ndipo nthawi yocheperako ndi 2. Kupindika kwa chingwe kumayimira kuchuluka kwa kutalika kwa chingwe pamene chili ndi kulemera kwa makilogalamu 80 panthawi yopuma.
