Pali zinayi zomwe zimayambitsa kulephera kwamphira zisindikizo: zolakwika zamapangidwe, zolakwika pakusankha zinthu, zovuta zamtundu wa chisindikizo, ndikugwiritsa ntchito molakwika.
1. Zolakwika za kamangidwe kaŵirikaŵiri zimadza chifukwa chakuti okonzawo samvetsa mokwanira za chinthucho.
Mwachitsanzo, kuyerekezera kosakwanira kwa kukakamizidwa koyendetsedwa ndi chinthu chosindikizira, kumvetsetsa kolakwika kwa kugawa kwa kupsinjika kwa kulumikizidwa pamalo osindikizira, ndi mapangidwe osayenera a poyambira poyika chinthu chosindikizira.Finite Element Analysis (FEA) nthawi zambiri amagwiritsidwa ntchito kuthandizira pakupanga ndi kulephera kusanthulazisindikizo.
2. Cholakwika chosankha zinthu
Zida zosindikizira za rabara zodziwika bwino zimaphatikizapo EPDM, NBR, VMQ, FKM, ndi CR.Ma rubber awa ali ndi mawonekedwe ndi ntchito zosiyanasiyana.Kusankhidwa kwa zipangizo kuyenera kuganiziridwa kuchokera kuzinthu zambiri, monga kutentha kwa ntchito, kaya zinthuzo zimagonjetsedwa ndi sing'anga, kuuma kwa zinthuzo, kuponderezedwa kwamuyaya, ndi kuvala kukana.
Zolakwika zosankha zinthu nthawi zambiri zimayamba chifukwa cha okonza sadziwa momwe zinthu zimagwirira ntchito.Wopereka chisindikizo cha rabara wodziwa bwino amatha kuwonetsa nkhani zosankhidwa kuyambira pachiyambi.
3. Kusindikiza khalidwe
Ubwino wopangira zisindikizo umagwirizana kwambiri ndi kudalirika kwa chinthu chomaliza.Mavuto omwe amapezeka nthawi zambiri amaphatikizapo kusakhazikika kwazinthu zopangira, kudyetsa kolakwika kwa zinthu zopangira mphira, kusungidwa kosayenera kwa zopangira kapena mphira wosakanizidwa (kuipitsidwa kwa mtanda), kusakanikirana kosagwirizana kwa zida za mphira, mikhalidwe yolakwika ya vulcanization (kutentha, nthawi, kuthamanga, etc.) kusungirako kosayenera kwa zinthu zosindikizira, ndi kugwiritsa ntchito molakwika nkhungu.Nkhanizi nthawi zambiri zimakhudza kuwongolera kwabwino pantchito yopanga.Gulu loyitanitsa liyenera kuwunika kangapo, kufufuza, ndi kuyesa zinthu posankha wopanga zida zosindikizira.Panthawi yoperekera, wopanga chisindikizo angafunikirenso kuti apereke lipoti loona komanso lolondola.
4. Kugwiritsa ntchito molakwika zisindikizo
Chisindikizo chabwino, ngati chikugwiritsidwa ntchito molakwika, chingathenso kulepheretsa mankhwala onse, monga kugwiritsa ntchito molakwika mafuta odzola.
Vuto lina lodziwika bwino ndi zolakwika za unsembe.Mwachitsanzo, kupotoza kunachitika panthawi ya msonkhano wa O-ring;Kupanikizana kosagwirizana kwa chinthu chosindikizira chifukwa cha kuyika kosayenera;Mafuta osakwanira a zisindikizo ndi zolakwika zina.Ngati zolakwikazi zimayambitsidwa ndi wopanga zisindikizo, ndiye kuti izi zimatengedwa ngati nkhani ya khalidwe la kupanga
