M'dziko lovuta la makina ndi machitidwe a uinjiniya, kuchokera pampopi wamba kukhitchini kupita ku ma hydraulic ovuta a chombo cha m'mlengalenga, chigawo chimodzi chimagwira ntchito mwakachetechete koma chofunikira kwambiri kuwonetsetsa kukhulupirika kwa magwiridwe antchito: mphete yosindikiza, kapena O-ring. Lupu losavuta, lopangidwa ngati donati la elastomeric ndi luso lakapangidwe kake, lopangidwa kuti ligwire ntchito zingapo zofunika zomwe ndizofunikira pachitetezo, kuchita bwino, komanso magwiridwe antchito.
Pachimake chake, ntchito yoyamba komanso yofunika kwambiri ya mphete yosindikizira ndiyo kupanga ndi kusunga chisindikizo chodalirika pakati pa malo awiri kapena kuposerapo. Imakhala ngati chotchinga mkati mwa gland yotsekeka (poyambira pomwe imakhala), kuteteza kutuluka kwamadzi kapena mpweya wosafunika. Izi zimamasulira zinthu ziwiri zofunika: kuteteza kutulutsa kwazinthu zamkati (monga mafuta, mafuta, ozizira, kapena hydraulic fluid) kumalo akunja, ndikuletsa kulowetsa kwa zonyansa zakunja monga fumbi, dothi, chinyezi, kapena tinthu tating'ono takunja. Pokhala ndi media, imawonetsetsa kuti makina amagwira ntchito monga momwe adapangidwira, kusunga madzi ofunikira, kusunga kupanikizika, ndikupewa kuipitsidwa ndi chilengedwe kapena zoopsa zachitetezo monga poterera kapena zoopsa zamoto. Popatula zowononga, imateteza zida zamkati zomwe zimakhudzidwa kuti zisakhumudwitse, dzimbiri, ndi kuvala msanga, potero zimatalikitsa moyo wa gulu lonse.
Kupitilira kusindikiza kosavuta, mphetezi ndizofunikira pakuwongolera kuthamanga. M'machitidwe osinthika pomwe zigawo zimasuntha (monga ma pistoni a hydraulic kapena ma shaft ozungulira), mphete yosindikizira yopangidwa bwino komanso yoyikidwa imasintha kusintha kwamakanikizidwe. Pansi pa kukakamizidwa kwa dongosolo, imapunduka pang'ono, ikukanikizidwa pamakoma a gland ndi mphamvu yayikulu. Kudzilimbitsa nokha kumeneku kumakulitsa luso losindikiza molingana ndi kukanikiza komwe kumagwiritsidwa ntchito, ndikupanga chisindikizo cholimba kwambiri pomwe chikufunika. Kutha kuthana ndi zovuta zosiyanasiyana, kuchokera ku malo opanda kanthu mpaka kupanikizika kwambiri, kumawapangitsa kukhala osinthasintha m'mafakitale.
Chinthu chinanso chofunikira, ngakhale nthawi zambiri chimanyalanyazidwa, ntchito ndikugwirizanitsa ndi kugwedezeka. Kulekerera kwa kupanga ndi kupsinjika kwa magwiridwe antchito kumatanthauza kuti malo okwererako sakhala ogwirizana bwino ndipo amatha kusuntha. Mapangidwe a elastomeric a mphete zomata amawalola kuti azikakamira, kutambasula, ndi kusinthasintha, kutengera kusiyanasiyana pang'ono, ma eccentricities, ndi kugwedezeka kwamphamvu popanda kusokoneza chisindikizo. Kusinthasintha kumeneku kumakwaniritsa zophophonya zomwe zikanapangitsa njira zotayikira mu chisindikizo cholimba, kuwonetsetsa kuti zimagwira ntchito mosasinthasintha pansi pa zochitika zenizeni, zomwe sizili bwino.
Kuphatikiza apo, mphete zosindikizira zimagwira ntchito yofunika kwambiri pakulekanitsa ma media osiyanasiyana. M'makina ovuta, chinthu chimodzi chimatha kulumikizana pakati pamadzi awiri osiyanasiyana omwe sayenera kusakanikirana. Mphete yosindikizira yoyikidwa bwino imakhala ngati gawo, kusunga, mwachitsanzo, mafuta opaka mosiyana ndi ozizira kapena mafuta. Kupatukana kumeneku n'kofunika kwambiri kuti pakhale kukhulupirika kwa mankhwala ndi ntchito zamadzimadzi aliwonse, kuteteza machitidwe omwe angayambitse kupanga matope, kutaya mafuta, kapena kulephera kwa dongosolo.
Pomaliza, ntchito ya mphete yosindikiza imalumikizidwa mwachindunji ndi kapangidwe kake. Akatswiri amasankha mankhwala enieni-monga Nitrile (NBR) a mafuta opangidwa ndi petroleum, Fluorocarbon (FKM/Viton) chifukwa cha kutentha kwambiri ndi mankhwala amphamvu, kapena Silicone (VMQ) chifukwa cha kutentha kwakukulu-kuti azichita pansi pa zovuta za chilengedwe. Chifukwa chake, ntchito ya mpheteyo imafikira kupirira kutentha kwakukulu (konse kokwera ndi kotsika), kukana ma oxidation, ozoni, ndi cheza cha UV, ndikusunga mphamvu ndi kusindikiza kwa nthawi yayitali popanda kunyozeka.
Mwachidule, mphete yosindikizira yodzichepetsa ndi mwala wapangodya wopangidwa ndi makina ambiri. Sikuti ndi gasket wamba koma ndi gawo losinthika lomwe limapangidwa kuti lisindikize, liteteze, lilamulire kukakamiza, kubweza mayendedwe, ma TV olekanitsa, komanso kupirira madera ovuta. Ntchito yake yodalirika ndi yoyambira, kuwonetsetsa kuti machitidwe kuchokera ku zida za tsiku ndi tsiku kupita kuzinthu zapamwamba zamafakitale ndi zamlengalenga zimagwira ntchito motetezeka, moyenera, komanso modalirika, ndikupangitsa kuti ikhale ngwazi yeniyeni yosadziwika muukadaulo.
