Chingwe Chokweza cha 7112A Chotsegula Mtundu Wawiri Wopindika Waya Chokweza Pulley Block ndi mbedza

• Mafotokozedwe Akatundu

Pulley ya snatch, yomwe imadziwikanso kuti snatch block, ndi chipangizo chosavuta koma chanzeru chomwe chimagwiritsidwa ntchito kusintha njira ya chingwe kapena chingwe pamene chili ndi mphamvu. Chimakhala ndi gudumu lozungulira lomwe lili mu chimango, zomwe zimathandiza kuti chingwecho chilowe mu groove ndikutsogoleredwa panjira yake. Kapangidwe kameneka kamachepetsa kukangana ndipo kamaletsa kusweka kwa chingwe, zomwe zimapangitsa kuti chingwecho chizigwira ntchito bwino ngakhale mutagwira ntchito ndi katundu wolemera. Mu nthawi ya zodabwitsa zaukadaulo ndi makina ovuta, pulley yodzichepetsa imakhalabe chizindikiro cha kuphweka komanso kugwira ntchito bwino.

Pakatikati pake, pulley imagwira ntchito motsatira mfundo ya ubwino wa makina, zomwe zimathandiza ogwiritsa ntchito kunyamula kapena kusuntha zinthu zolemera popanda kugwiritsa ntchito mphamvu zambiri. Zinthu zofunika kwambiri pa dongosolo la pulley ndi izi:

Chingwe (Gudumu): Chigawo chapakati cha pulley, chomwe nthawi zambiri chimakhala chozungulira kapena chooneka ngati disk, chomwe chimazunguliridwa ndi chingwe kapena chingwe.
Chingwe kapena Chingwe cha Waya: Chinthu chosinthasintha chomwe chimazungulira chipolopolocho, kutumiza mphamvu kuchokera kumapeto ena kupita kwina.
Katundu: Chinthu chomwe chikunyamulidwa kapena kusunthidwa ndi makina opopera.
Khama: Mphamvu yomwe imagwiritsidwa ntchito pa chingwe kapena chingwe cha waya kuti inyamule kapena kusuntha katundu.
Ma pulley amagawidwa m'magulu kutengera kapangidwe kake ndi kapangidwe kake. Magulu awa akuphatikizapo ma pulley okhazikika, ma pulley osunthika, ndi ma pulley ophatikizika. Mtundu uliwonse umapereka zabwino zosiyanasiyana pankhani ya ubwino wa makina ndi kusinthasintha kwa magwiridwe antchito.

Pokhala ndi mitolo iwiri yoyikidwa pa axle yofanana, dongosolo la pulley ili limachulukitsa mphamvu yonyamulira poyerekeza ndi ina ya sheave imodzi. Kuphatikiza apo, kuphatikiza kwa mbedza kumawonjezera kugwiritsidwa ntchito kwake mwa kuthandizira kulumikiza mosavuta ku malo osiyanasiyana omangira kapena katundu.

Kukulitsa Mphamvu:
Chimodzi mwa zabwino zazikulu zapulley yolumikizira zingwe ziwiriIli ndi mphamvu zokulitsa mphamvu zake. Mwa kugawa katundu pakati pa mitolo iwiri, imachepetsa kukangana ndipo imachepetsa khama lofunika ponyamula zinthu zolemera. Mbali imeneyi ndi yothandiza makamaka pazochitika zomwe kunyamula kapena kukweza pamanja kumakhudzidwa, chifukwa zimathandiza ogwiritsa ntchito kuchita ntchito mosavuta komanso mwachangu.

Kuphatikiza apo, ubwino wa makina womwe umaperekedwa ndi kapangidwe ka double sheave umalola kuti ntchito iyende bwino komanso kuchepetsa chiopsezo cha kuvulala kokhudzana ndi kupsinjika pakati pa ogwira ntchito. Kaya ndi kunyamula zida pamalo omanga kapena kunyamula katundu m'mafakitale, makina opukutira awa amathandiza kuti ntchito ziyende bwino komanso kuti zinthu ziyende bwino.

Pewani Kudzaza Zinthu Mopitirira Muyeso: Musamachulukitse katundu wa pulley ya snatch. Kudzaza zinthu mopitirira muyeso kumawonjezera chiopsezo cha kulephera kwa zida ndipo kumaika pachiwopsezo antchito omwe ali pafupi.

Kukhazikitsa Koyenera: Onetsetsani kuti chingwe cha waya chalumikizidwa bwino kudzera mu pulley sheave ndipo chalumikizidwa bwino ku mfundo za nangula.

Pewani Kuyika zinthu m'mbali: Onetsetsani kuti chogwirira cha waya cholumikizidwa bwino ndi komwe chikukokedwa. Kuyika zinthu m'mbali kungayambitse kuwonongeka msanga kapena kulephera kwa dongosolo la chogwirira.
