Zisindikizo zamakina za WMFWT Metal Bellow zimalowa m'malo mwa Burgmann MFLWT80 chifukwa cha kutentha kwambiri komwe kumagwiritsidwa ntchito mu mapampu amafuta ndi mapampu a mankhwala.

Ubwino wa zisindikizo zamakina zachitsulo

Zisindikizo zachitsulo zokhala ndi bellows zili ndi ubwino wambiri poyerekeza ndi zisindikizo zodziwika bwino. Ubwino woonekeratu ndi monga:

- Palibe mphete ya o-dynamic yomwe imachotsa mwayi wopachikidwa kapena kutayika kwa shaft.

- Mivi yachitsulo yolinganizidwa bwino imalola chisindikizocho kuthana ndi kupsinjika kwakukulu popanda kutentha komwe kukukulirakulira.

- Kudziyeretsa. Mphamvu ya centrifugal imataya zinthu zolimba kuchokera pamwamba pa chisindikizo - Kapangidwe kake kamalola kulowa m'mabokosi omatira olimba

- Ngakhale kukweza nkhope

- Palibe ma Springs otsekeka

Nthawi zambiri zisindikizo zachitsulo zimaonedwa ngati zisindikizo za kutentha kwambiri. Koma zisindikizo zachitsulo nthawi zambiri zimakhala zothandiza pa ntchito zina zambiri zosindikizira. Chofala kwambiri mwa izi ndi kugwiritsa ntchito mankhwala, mapampu amadzi wamba. Kwa zaka zambiri, mitundu yotsika mtengo ya zisindikizo zachitsulo zakhala zikugwiritsidwa ntchito bwino kwambiri m'makampani opanga madzi otayira / zimbudzi komanso m'minda yaulimi popopera madzi othirira. Zisindikizo zimenezi nthawi zambiri zimapangidwa ndi zisindikizo zopangidwa m'malo mwa zisindikizo zolumikizidwa. Zisindikizo zachitsulo zolumikizidwa zimakhala zolimba kwambiri ndipo zimakhala ndi mawonekedwe opindika komanso obwezeretsa omwe ndi abwino kwambiri pogwirizanitsa nkhope za zisindikizo koma zimawononga ndalama zambiri popanga. Zisindikizo zachitsulo zolumikizidwa sizimatopa kwambiri ndi zitsulo.

Popeza zisindikizo zachitsulo za bellows zimangofuna mphete imodzi yokha ya o-ring, ndipo chifukwa mphete ya o-ringyo imatha kupangidwa ndi PTFE, zisindikizo zachitsulo za bellows ndi njira yabwino kwambiri yogwiritsira ntchito mankhwala pomwe Kalrez, Chemrez, Viton, FKM, Buna, Aflas kapena EPDM sizigwirizana. Mosiyana ndi chisindikizo cha ASP Type 9, mphete ya o-ring sidzayambitsa kuwonongeka chifukwa siisinthasintha. Kuyika ndi mphete ya PTFE kuyenera kuchitidwa mosamala kwambiri pamwamba pa shaft, komabe zisindikizo za PTFE zomangidwa ndi capsule zimapezekanso m'makulidwe ambiri kuti zithandize kutseka pamwamba mosakhazikika.
