Kodi malamba a nthawi ndi chiyani?

Malamba okhala ndi nthawi ndi magulu okhuthala opangidwa ndi mphira omwe amakhala ndi mano olimba komanso zitunda mkati mwake zomwe zimawathandiza kuti azilumikizana ndi ma cogwheels a crankshafts ndi camshafts. Amagwiritsidwa ntchito kupatsa mphamvu ndikuwongolera magwiridwe antchito pamapampu amadzi, mapampu amafuta, ndi mapampu a jakisoni, monga momwe zimafunira ndi kapangidwe ka injini. Amagwiritsidwa ntchito kwambiri m'mainjini oyatsira mkati kuti mavavu a injini atseguke ndi kutseka motsatizana ndi nthawi.

 

Kodi malamba a nthawi ndi chiyani?

Malamba anthawi yabwino kwambiri ali ndi ntchito ndi ntchito zotsatirazi:

Zimagwira ntchito yofunika kwambiri pakuyendetsa bwino ntchito yoyatsira poyendetsa bwino pisitoni ndi mavavu.

Imayendetsa ntchito ya valve polumikiza crankshaft ndi camshaft pamodzi.

Zimasamalira kutsegulira kophatikizana ndi kutseka kwa ma valve a injini.

Zimathetsa kufunika kwa mphamvu zakunja kuti zigwiritse ntchito kutsegula ndi kutseka kwa ma valve pogwiritsa ntchito mphamvu zamakina a injini yoyaka moto.

Chimodzi mwazinthu zofunika kwambiri komanso kugwiritsa ntchito malamba a nthawi ndikuti amaletsa pisitoni kuti isamenye ma valve.

Ngakhale ndi lamba limodzi kapena chipangizo chimodzi, zimathandizira kwambiri pakugwira ntchito kwa zigawo zingapo monga sprocket yapamwamba ya shaft, low balance shaft sprocket, camshaft belt drive gear, balance belt drive gear, balance belt tensioner roller, ndi timing belt tensioner roller.

 

Kodi njira yogwirira ntchito ya malamba a nthawi ndi iti?

Malamba a nthawi amagwirizanitsa ntchito yotseka-kutsegula ndi nthawi ya crankshaft, camshaft, ndi valve exhaust. Zimathandizira kutulutsa mafuta ndi mpweya kulowa mu injini yoyaka, komanso kuwongolera valavu yotulutsa mpweya kuti utsi kapena utsi utuluke. Lambayo imasunga injiniyo kuti ikhale yogwirizana ndikusunga luso lake ndi zokolola.

 

Ndi liti pomwe mungasinthe lamba wanthawi?

Kupezeka kwa zizindikilo izi kukuwonetsa kufunika kosintha lamba wakale komanso wotha ndikusintha lamba watsopano wanthawi:

Kuchepetsa mphamvu ya injini

Kutentha kwa injini

Kuchitika kwa kugwedezeka kapena kugwedezeka mu injini

Kuvuta kuyambitsa makina kapena galimoto

Kusisita kapena kusisita phokoso lochokera pa lamba

Mkokomo wa phokoso umamveka kuchokera mu injini

Mafuta akutuluka mu injini

Kusakhazikika pakugwira ntchito kwa kuwala kwa injini
