Cov welded bellows nyob rau hauv lubhlau bellows mechanical sealstsis tsuas yog muaj cov nyhuv ntawm lub caij nplooj ntoos hlav nro, tab sis kuj muaj cov qauv sib khi. Yog li ntawd, tus qauv tsim tsis xav tau lub nplhaib txav O- nplhaib, thaum cov nyhuv ntawm lub caij nplooj ntoos hlav nro nyob rau hauv cov khoom siv sib khi dav dav (lub nplhaib thawb hom) tsuas yog tswj xyuas qhov compression thiab sib npaug ntawm qhov sib txhuam. Piv nrog rau cov khoom siv hluav taws xob dav dav, cov hlau nqus hlau tshuab ntsaws ruaj ruaj muaj ntau yam zoo, uas tuaj yeem ua tiav raws li hauv qab no.
1. High precision: lub welded bellows muaj cov nyhuv ntawm nro caij nplooj ntoos hlav thiab yog ib tug ua ke ntawm countless nro springs, yog li nws daws tau qhov teeb meem ntawm lub caij nplooj ntoos hlav nro deformation vim centrifugal quab yuam, rotates ntawm qhov siab tsim nyog, thiab sealing nto yog nias tusyees.
2. Zoo oscillation kuj thiab saj zawg zog: lub bellows muaj siab saj zawg zog thiab zoo nqus nyhuv ntawm oscillation, yog li nws muaj peev xwm muaj peev xwm ntawm radial runout, axial clearance, oscillation thiab viav vias kom tsis txhob to.
3. Cov qauv yooj yim: qauv yooj yim thiab sib dhos yooj yim. Tsis zoo li lub caij nplooj ntoos hlav nro, uas yog tsim los ntawm ntau qhov chaw, kev siv yog complex.
4. Adapt to a variety of temperature conditions: the welded bellows has a small coefficient of thermal expansion and can be used at low or high temperature. And there is no o - ring disjoint temperature limit, the design is more comfortable
5. Adapt to high pressure: due to the balance effect of the bellows itself, the sealing surface area can be adjusted to offset the fluid pressure, reduce the friction of the sealing surface, and then reduce the amount of heating and wear. It can be applied to high pressure.
6. Los tiv thaiv lub tshuab: lub tshuab foob ntawm welded bellows tsis muaj O- nplhaib, yog li kev hnav ntawm ncej lossis lub tes tsho los ntawm kev puas tsuaj ntawm O- nplhaib yuav tsis tshwm sim. Nws muaj cov nyhuv tiv thaiv cov ncej, yog li tsis tas yuav tsum tau nruab lub tes tsho ncej.
7. Habitual corrosive kua: cov welded bellows yog ua los ntawm corrosive heev Hastelloy 276 thiab lwm yam ntaub ntawv kom tsis txhob muaj corrosion ntawm nro lub caij nplooj ntoos hlav thiab O- nplhaib, yog li lub sealing tiav.
8. Tsis muaj kev ncua: siv lub nplhaib sib tsoo tshuab foob, ib qho me me ntawm cov kua xau ua kom ruaj khov thiab tso rau hauv huab cua los tiv thaiv kev txav ntawm lub nplhaib txav O- nplhaib. Yog li ntawd, lub adhesion quab yuam ntawm lub sealing kawg lub ntsej muag ua tsis muaj zog los yog ploj mus, thiab ces ua rau to. Lub tshuab foob ntawm welded hlau bellows tsis muaj O- nplhaib, uas yuav tsis raug cuam tshuam txawm tias muaj cov khoom ruaj khov. Nws tuaj yeem tig tau nyab xeeb thiab txuas ntxiv nws lub neej kev pabcuam.
9. Screw pumping effect: lub tshuab nqus dej nws tus kheej muaj cov ntsia hlau siv cov nyhuv, uas tuaj yeem ua tau zoo sib xws rau cov kua dej uas muaj cov khoom siv thiab pab ua kom dej ntws.
