Kodi pulley ndi chiyani?

Pulley ndi chipangizo chosavuta kugwiritsa ntchito kapena makina (omwe angakhale amatabwa, achitsulo, kapena apulasitiki) omwe ali ndi chingwe chosinthasintha, chingwe, unyolo, kapena lamba wonyamulidwa pamphepete mwa gudumu. Gudumu, lomwe limatchedwanso sheave kapena drum, likhoza kukhala la kukula kulikonse ndi kutalika kulikonse.

 

Pulley ingagwiritsidwe ntchito payekhapayekha kapena pamodzi kuti ipereke mphamvu ndi kuyenda. Zipangizozi zopangidwa mwaluso komanso zamphamvu zimathandiza kuyenda ndikuwongolera mphamvu. Mwanjira imeneyi, kudzera mu mphamvu zawo zochepa, zimathandiza kusuntha zinthu zazikulu.

 

Dongosolo la Pulley

Ndi pulley imodzi yokha, njira yokhayo ya mphamvu yogwiritsidwa ntchito ndiyo ingasinthidwe. Pulley sikuti imangosintha njira ya mphamvu yogwiritsidwa ntchito komanso imachulukitsa mphamvu yolowera pamene mphamvu ziwiri kapena zingapo zikugwiritsidwa ntchito mu dongosolo. Dongosolo la pulley limapangidwa ndi magawo atatu:

chingwe

gudumu

chitsulo

Ma pulley amapangitsa ntchito monga kunyamula katundu wolemera ndi kuyenda kukhala kosavuta. Amagwiritsa ntchito gudumu ndi chingwe kunyamula katundu wolemera. Amatha kuzunguliridwa. Ma pulley apulasitiki amapezekanso pamsika ndipo amagwiritsidwa ntchito kuthandiza kunyamula mitolo yaying'ono ndi katundu. Kutengera kusintha kwa njira ndi kukula kwa mphamvu, amagawidwa m'magulu osiyanasiyana.

 

Mitundu yosiyanasiyana ya ma pulley imagwiritsidwa ntchito pazifukwa zosiyanasiyana. Izi ndi izi:

Pulley Yokhazikika

Kusuntha Pulley

Pulley Yophatikizana

Block ndi Tackle Pulley

Pulley ya Cone

Pulley Yozungulira Yamaso

Pulley Yokhazikika ya Diso

 

Kugwiritsa Ntchito Pulleys Mwaluso

Ma pulley ankagwiritsidwa ntchito makamaka kuti ntchito yonyamula zinthu zolemera ikhale yosavuta. Pulley ingagwiritsidwe ntchito yokha kapena pamodzi ndi ma pulley ena ponyamula zida. Zina mwa ntchito zake zambiri ndi izi:

Ma pulley amagwiritsidwa ntchito kunyamula madzi kuchokera m'zitsime.

Ma pulley angapo amagwiritsidwa ntchito poyendetsa ma elevator ndi ma escalator.

Ma pulley nthawi zambiri amagwiritsidwa ntchito m'ma derick amafuta ndipo angagwiritsidwe ntchito powonjezera makwerero.

Amagwiritsidwa ntchito kwambiri potumiza katundu ndi ntchito zapamadzi.

Amagwiritsidwa ntchito powonjezera phindu la makina akagwiritsidwa ntchito pa zida zamafakitale ndi makina olemera.

Makina opukutira miyala amagwiritsidwa ntchito ndi okwera miyala kuti athandize kukwera. Makina opukutira amathandiza wokwerayo kukwera mmwamba pamene akukoka chingwecho motsatira njira yotsikira pansi.

Ma pulley amagwiritsidwa ntchito mu zida zambiri zonyamulira zolemera zomwe zimagwiritsidwa ntchito pochita masewera olimbitsa thupi. Amagwiritsidwa ntchito kuwongolera ngodya yomwe zolemera zimakwezedwa pamene akusunga zolemerazo pamalo oyenera.
