Kodi mungamvetse bwanji kuti sensor yamafuta ndi yolakwika?

Kuthamanga kwa mafuta mu injini ya galimoto kumagwira ntchito yofunika kwambiri powonetsetsa kuti mafuta odzola afika pamalo ofunikira, kuphatikizapo ma camshaft, mainshaft ndi ma bearings a balanceshaft. Izi zimathandizira kuchepetsa kuwonongeka kwa magawo a injini,…

Kuthamanga kwa mafuta mu injini ya galimoto kumagwira ntchito yofunika kwambiri powonetsetsa kuti mafuta odzola afika pamalo ofunikira, kuphatikizapo ma camshaft, mainshaft ndi ma bearings a balanceshaft. Izi zimathandiza kuchepetsa kuvala kwa mbali za injini, kuonetsetsa kuti injiniyo siitenthedwa ndipo ikupitiriza kuyenda bwino. Mukayang'ana kuchuluka kwa kuthamanga kwamafuta, dziwani kuti nyengo yozizira kupanikizika kumakhala kokulirapo chifukwa chamafuta (omwe amadziwikanso kuti viscosity) yamafuta.

Kodi mafuta opangira mafuta amagwirira ntchito bwanji

Mapangidwe amkati a makina opangira mafuta amatengera mtundu wake: magetsi kapena makina. Makina oyesa kuthamanga kwamagetsi amagwiritsa ntchito kasupe yemwe amayendetsedwa ndi kuthamanga kwamafuta. Chubu chopiringidwa, chotchedwa babu, chimamangiriridwa ku nyumba yakunja ya geji yamafuta ndi njira yolumikizira pansi pa singanoyo. Mafuta amaperekedwa ku babu pansi pa kupanikizika, monga mu injini ya galimoto, kuchokera ku chitoliro choperekera chomwe chimapangitsa babu kuti ayese kudziwongola. Kuthamanga kumeneku kumasuntha singano ya mafuta pazitsulo kuti iwonetse kuchuluka kwa mphamvu ya mafuta mu injini.

Chiyerekezo chamagetsi chamagetsi chimagwiritsa ntchito cholumikizira ndi chozungulira kutumiza ma siginecha amagetsi kugeji yoyezera kuthamanga kudzera pa koyilo yamabala a waya. Zigawozi zimalola dongosolo kuti lisinthe singano ya gauge kuti iwonetse kuthamanga koyenera. Mafuta amalowa kumapeto kwa gejiyo ndi kukanikiza pa diaphragm, yomwe imasuntha chopukuta mkati mwa gejiyo mmwamba ndi pansi pa tsamba lotha kupirira, ndikupanga chizindikiro chomwe chimasuntha singanoyo.

Magalimoto ena amagwiritsa ntchito nyali yochenjeza za kuchuluka kwa mafuta m'malo mwa choyezera kuthamanga kwamafuta. Pankhaniyi, kuwala kochenjeza kumalumikizidwa ndi sensa yomwe imagwiritsa ntchito chosinthira chosavuta / chozimitsa chomwe chimawerengera kuthamanga kwamafuta kudzera pa diaphragm yomwe imalumikizidwa ndi injini.

Zizindikiro za kunenepa kwambiri kwa mafuta

Makina opangira mafuta akasiya kugwira ntchito bwino, onetsetsani kuti makinawo akugwira ntchito. Zizindikiro zina zodziwika kuti sensor yamafuta sakugwira ntchito bwino ndi izi:

• Sensor yamphamvu yamafuta sikugwira ntchito: Zifukwa zamtunduwu kuyambira pamagetsi olakwika mpaka kufunika kosintha mafuta. Wokonza makina awone kuchuluka kwa mafuta.

• Kuyeza kwa mafuta kumatsika kwambiri, nthawi zambiri pansi pa 15-20 psi osagwira ntchito. Kuzizira kungayambitsenso kuthamanga kwa mafuta mpaka pampu yamafuta ikapereka mafuta ku injini.

• Kuyeza kwa mafuta kumakwera kwambirikapena kuposa 80 psi pamene mukuyendetsa galimoto, makamaka pa rpm yapamwamba. Eni magalimoto amatha kuyang'ana zolemba zawo kuti adziwe zambiri za kuchuluka kwa mphamvu yamafuta pamene injini ikuyenda pa RPM inayake.

Zifukwa Zina Zowerengera Kuthamanga Kwambiri kwa Mafuta kapena Kutsika kwa Mafuta

Kuphatikiza pa choyezera cholakwika cholakwika, zovuta zamakina a injini ndi magawo ena zimatha kuyambitsa kuwerengera kwakukulu kapena kutsika. Makanika amayang'ana madera ovutawa kuti awonetsetse kuti magawowa akugwirabe ntchito bwino ndipo sakuyambitsa mavuto amafuta.

• Mafuta ayenera kusinthidwa: Pakapita nthawi, mafutawo amawola ndipo amataya kukhuthala kwake, zomwe zimapangitsa kuti aziwerengera zochepa. Makanika amayang'ana momwe mafuta alili ndikusintha ngati kuli kofunikira.

• Sefa yotsekeka yamafuta imatha kuyambitsa kuthamanga kwamafuta kwambiri.: Pamenepa, makaniko adzasintha fyuluta ndi mafuta.

• Malo osungiramo mafuta otsekedwa angayambitsenso kuwerenga kwakukulu.: Pamenepa, makaniko amatsuka mafuta pamene akusintha mafuta.

• Nthawi zina mafuta olakwika zimayambitsa kuthamanga kwa mafuta. Makaniko amawonetsetsa kuti galimoto yanu yadzazidwa ndi mafuta oyenera ndikuyisintha ndi giredi yoyenera ngati kuli kofunikira.

• Zovala zotha nthawi zina amachepetsa kuthamanga kwa mafuta. Ngati ndi kotheka, zimango adzalowa m'malo mayendedwe.

• Pampu yamafuta osweka zitha kupangitsa kuti muchepetse kuthamanga kwamafuta. Pankhaniyi, makaniko adzalowa m'malo pampu yamafuta.
