Kodi pulley ndi chiyani?

Pulley ndi chida chosavuta chamakina kapena makina (omwe atha kukhala matabwa, zitsulo, kapena pulasitiki) omwe amakhala ndi chingwe, chingwe, unyolo, kapena lamba wonyamulidwa pamphepete mwa gudumu. Gudumu, lomwe limatchedwanso mtolo kapena ng'oma, likhoza kukhala la kukula ndi kutalika kulikonse.

 

Pulley ingagwiritsidwe ntchito payekha kapena kuphatikiza kufalitsa mphamvu ndi kuyenda. Izi zidapangidwa mwaluso, zamphamvu zimathandizira kusuntha ndikuwongolera kupsinjika. Mwanjira imeneyi, kupyolera mu mphamvu yawo yaing’ono, amalola kusuntha kwa zinthu zazikulu.

 

Pulley System

Ndi pulley imodzi, njira yokhayo yogwiritsira ntchito mphamvu ingasinthidwe. Pulley sikuti imangosintha njira yomwe imagwiritsidwa ntchito komanso imachulukitsa mphamvu yolowera pamene mphamvu ziwiri kapena zingapo zikugwiritsidwa ntchito mu dongosolo. Pulley system imapangidwa ndi magawo atatu:

chingwe

gudumu

gwero

Pulleys imapangitsa ntchito ngati kunyamula zolemetsa komanso kuyenda mosavuta. Imagwiritsa ntchito gudumu ndi chingwe kunyamula katundu wolemera. Amatha kuzunguliridwa. Mapuleti apulasitiki amapezekanso pamsika ndipo akugwiritsidwa ntchito kuthandizira kunyamula mitolo yaing'ono ndi katundu. Malingana ndi kusintha kwa njira ndi kukula kwa mphamvu, amagawidwa m'mitundu yosiyanasiyana.

 

Mitundu yosiyanasiyana ya ma pulleys imagwiritsidwa ntchito pazolinga zosiyanasiyana. Ali:

Pulley Yokhazikika

Kusuntha Pulley

Compound Pulley

Block ndi Tackle Pulley

Cone Pulley

Swivel Eye Pulley

Fixed Diso Pulley

 

Kugwiritsa Ntchito Pulleys

Mapulani ankagwiritsidwa ntchito makamaka kuti ntchito yonyamula zinthu zolemera ikhale yosavuta. Pulley itha kugwiritsidwa ntchito yokha kapena molumikizana ndi ma pulleys ena kunyamula zida. Zina mwazogwiritsidwa ntchito kwake ndi izi:

Mapulani amagwiritsidwa ntchito kunyamula madzi m'zitsime.

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

Pulleys amagwiritsidwa ntchito nthawi zonse popanga mafuta ndipo amatha kugwiritsidwa ntchito kukulitsa makwerero.

Amagwiritsidwa ntchito kwambiri m'malo otumizira komanso m'madzi.

Amagwiritsidwa ntchito kuwonjezera mwayi wamakina akamagwiritsidwa ntchito pazida zamafakitale komanso makina olemera.

Njira ya pulley imagwiritsidwa ntchito ndi okwera miyala kuti athandizire kukwera. Pulley imathandiza wokwera kusunthira mmwamba pamene amakoka chingwe kumunsi.

Pulleys amagwiritsidwa ntchito pazida zambiri zonyamulira zitsulo zomwe zimapangidwira kuchita masewera olimbitsa thupi. Amagwiritsidwa ntchito kuwongolera mbali yomwe miyeso imakwezedwa ndikusunga zolemera pamalo oyenera.
