Indlela yokuqonda ukuthi inzwa yokucindezela uwoyela inephutha?
Okuqukethwe
Umfutho kawoyela enjinini yemoto udlala indima ebalulekile ekuqinisekiseni ukuthi izinto zokugcoba zifinyelela ezindaweni ezidingekayo, okuhlanganisa ama-camshaft, ama-mainshaft nama-balanceshaft bearings. Lokhu kusiza ukunciphisa ukuguga kwezingxenye zenjini,…
Umfutho kawoyela enjinini yemoto udlala indima ebalulekile ekuqinisekiseni ukuthi izinto zokugcoba zifinyelela ezindaweni ezidingekayo, okuhlanganisa ama-camshaft, ama-mainshaft nama-balanceshaft bearings. Lokhu kusiza ukunciphisa ukuguga ezingxenyeni zenjini, kuqinisekisa ukuthi injini ayishisi ngokweqile futhi iyaqhubeka nokusebenza kahle. Uma uhlola igeji yomfutho kawoyela, qaphela ukuthi emakhazeni amazinga okucindezela aphakeme ngenxa yokuqina (okubuye kwaziwe ngokuthi i-viscosity) yamafutha.
Isebenza kanjani igeji yokucindezela uwoyela
Isakhiwo sangaphakathi segeji yokucindezela uwoyela ngokuyinhloko sincike ohlotsheni lwaso: ugesi noma umshini. I-mechanical gauge ye-pressure gauge isebenzisa isiphethu esisebenza ngaphansi komfutho kawoyela. Ishubhu eligoqiwe, elibizwa ngokuthi i-bulb, lixhunywe endaweni engaphandle yegeji kawoyela kanye nasendleleni yokuxhumanisa phansi yenaliti. Amafutha anikezwa isibani ngaphansi kwengcindezi, njengasenjinini yemoto, ephuma epayipini lokunikezela elibangela ukuthi isibani sizame ukuziqondisa ngokwaso. Lokhu kucindezela kuhambisa inaliti yokucindezela uwoyela kuphaneli yensimbi ukukhombisa izinga lomfutho kawoyela enjinini.
Igeji ye-pressure gauge isebenzisa iyunithi yokudlulisela kanye nesekhethi ukuthumela amasignali kagesi kugeji yokucindezela ngekhoyili yenxeba lentambo. Lezi zingxenye zivumela isistimu ukuthi iguqule inaliti yegeji ukuze ibonise ukucindezela okulungile. Amafutha angena ekugcineni kwegeji bese ecindezela i-diaphragm, enyakazisa isesula ngaphakathi kwegeji phezulu naphansi kwensingo ephikisayo, okwenza isignali ehambisa inaliti yegeji.
Ezinye izimoto zisebenzisa isibani esiyisixwayiso sezinga likawoyela esikhundleni segeji yomfutho kawoyela. Kulesi simo, ukukhanya okuyisixwayiso kuxhunywe kunzwa esebenzisa inkinobho yokuvula/ukuvala elula efunda umfutho kawoyela nge-diaphragm exhunywe enjinini.
Izimpawu zegeji yomfutho kawoyela omubi
Uma inzwa yomfutho kawoyela iyeka ukusebenza kahle, hlola umakhenikha ukuthi iyasebenza. Ezinye zezimpawu ezijwayelekile zokuthi inzwa yomfutho kawoyela ayisebenzi kahle zihlanganisa:
Inzwa yomfutho kawoyela ayisebenzi: Izizathu zalolu hlu ukusuka kugeji yokucindezela enephutha ukuya esidingweni sokushintsha uwoyela. Yiba umakhenikha ahlole izinga likawoyela.
Igeji yomfutho kawoyela iphansi kakhulu, ngokuvamile ngaphansi kwe-15-20 psi ngokungenzi lutho. Isimo sezulu esibandayo singabangela nomfutho kawoyela wehle kuze kube yilapho iphampu kawoyela ihambisa uwoyela enjinini.
Igeji yomfutho kawoyela iphezulu kakhulunoma ngaphezulu kwama-psi angama-80 ngenkathi ushayela, ikakhulukazi nge-rpm ephezulu. Abanikazi bezimoto bangabheka amamanuwali abo ukuze bathole ulwazi lokuthi igeji yokulinganisa uwoyela kufanele ibe phezulu kangakanani uma injini isebenza nge-RPM ethile.
Ezinye Izimbangela Zokufundwa Kwezinga Lokucindezela Kawoyela Okuphezulu noma Okuphansi
Ngokungeziwe kugeji yokucindezela engalungile, izinkinga ngezinye izinhlelo zenjini nezingxenye zingabangela ukufundwa okuphezulu noma okuphansi. Umakhenikha uzohlola lezi zindawo eziyinkinga ukuze aqinisekise ukuthi lezi zingxenye zihlala zisebenza kahle futhi azibangeli izinkinga zokucindezela kukawoyela.
Uwoyela udinga ukushintshwa: Ngokuhamba kwesikhathi, amafutha ayabola futhi alahlekelwe yi-viscosity yawo, okuholela ekufundweni kwegeji ephansi. Umakhenikha uzohlola isimo samafutha futhi asishintshe uma kunesidingo.
Isihlungi sikawoyela esivalekile singaholela ekucindezelweni kawoyela okuphezulu.: Kulesi simo, umakhenikha uzoshintsha isihlungi namafutha.
Igalari yamafutha evinjiwe nayo ingabangela ukufundwa okuphezulu.: Kulesi simo, umakhenikha ususa uhlelo lukawoyela lapho eshintsha uwoyela.
Kwesinye isikhathi uhlobo olungalungile lwamafutha kubangela umfutho ophakeme kawoyela. Umakhenikha uzoqinisekisa ukuthi imoto yakho igcwele izinga elifanele likawoyela futhi esikhundleni salo uzofaka izinga elifanele uma kunesidingo.
Ama-bearings agugile ngezinye izikhathi kwehlisa umfutho kawoyela. Uma kunesidingo, umakhenikha uzothatha indawo yama-bearings.
Iphampu yamafutha ephukile kungaholela esilinganisweni esiphansi somfutho kawoyela. Kulesi simo, umakhenikha uzothatha indawo yepompo yamafutha.
