Chii chinonzi mechanical seals? Michina yemagetsi ine shaft inotenderera, senge pombi uye compressor, iyo inowanzonzi "inotenderera muchina". Mechanical chisimbiso imhando yekurongedza yakaiswa pane magetsi ekufambisa shaft yemuchina unotenderera. Vane zvakasiyana-siyana zvekushandisa, kubva kumotokari, ngarava, maroketi uye zvigadzirwa zvemaindasitiri ezvirimwa kusvika kune zvekugara.
Ndeipi basa guru re mechanical seal?
Themechanical sealsyakagadzirirwa kudzivirira mvura (mvura kana mafuta) inoshandiswa nemushini kubva pakudonha kuenda kunharaunda yekunze (atmosphere kana mvura). Iri basa remakanika chisimbiso rinobatsira kudzivirira kusvibiswa kwezvakatipoteredza, kuchengetedza simba uye kuchengetedza kwemuchina nekuvandudza kushanda kwemuchina.
Kana mechaniki chisimbiso kana gland kurongedza ikasashandiswa, mvura inodonha kuburikidza nepakati pakati pe shaft nemuviri. Kana chiri chekudzivirira kudonha kwemuchina, zvino shanda kushandisa chisimbiso chinhu chinodaidzwa kuti chisimbiso kurongedza pane shaft. Mhete yakaparadzana inoiswa pane shaft uye ganda remuchina kudzikisa kubuda kwemvura inoshandiswa mumushini pasina kukanganisa simba rekutenderera re shaft. Kuti uve nechokwadi cheizvi, chikamu chimwe nechimwe chinogadzirwa kune dhizaini chaiyo. Mechanical chisimbiso chinogona kudzivirira kuvuza kwezvinhu zvine njodzi kunyangwe pasi pemamiriro akaomarara ekuoma kwemakanika kana kudzvanywa kwakanyanya uye kumhanya kwakanyanya.
Iyo tekinoroji kuseri kwema mechanical seals
Nekuda kwemabasa ari pamusoro uye mashandisirwo, mechanical seal tekinoroji ndiyo hwerengedzo yemakanika engineering uye tekinoroji yekuita tekinoroji. Kunyanya, musimboti wemakanika chisimbiso tekinoroji iTribology (kukwenya, kupfeka uye lubrication) tekinoroji, iyo inoshandiswa kudzora kukweshera (kutsvedza) pamusoro pakati pemhete yakagadziriswa uye inotenderera mhete. Iyo mechaniki chisimbiso ine basa iri haingodzivise mvura kana gasi rinogadziriswa nemuchina kubva pakubuda kunze, asi zvakare kuvandudza kushanda kwemuchina, kuitira kubatsira kuchengetedza simba uye kudzivirira kusvibiswa kwezvakatipoteredza.
