Nei zvichinetsa kushandura hombe - caliber mavharuvhu? Ndeipi mhinduro?

(Pfupiso tsananguro)Pakati pevashandisi vanoshandisa yakakura - Diameter pasi rose mavharuvhu muhupenyu hwezuva nezuva.

Pakati pevashandisi vanoshandisa Huru - Divhesi Pasi rose muhupenyu hwezuva nezuva, ndiko kuti, DIEMATER CLOVES CLOVES ZVINOGONA KUTI VAVANZE MUDZIMAI KUTI UTSHURE DZIMAMBE Pakati pevashandisi vanoshandisa hombe - Divhesi remumumumu zuva nezuva, vanhu vanowanzo taura dambudziko racho, kuti Divhenekeri vanowanzove vari muzvenhau nenzira yakakura yekumanikidza, senge steam uye yakakwirira - kumanikidza mvura. Maitiro ekuvhara zvine simba zvine simba, zvinowanzowanikwa kuti kuchave nekudzikiswa, uye zvakaoma kuvhara. Chikonzero chedambudziko iri chinokonzerwa nechimiro chekugadzira vheji uye kushayikwa kwemunhu muganho wevanhu kubuda torque.

Kuongororwa kwezvikonzero zvekunetseka kwekuvhura uye kuvhara yakakura - Caliber Valves

Iyo yekupedzisira yakatwasuka inoburitsa simba remunhu mukuru ane makore makumi matanhatu -

Kazhinji, kutungamira kwekuyerera kweyekuvhara - kure nevharuvharuvhu kwakagadzirirwa kuve kwakaderera mukati nekukwira kunze. Kana munhu akavhara vharuvhu, muviri wemunhu unosundidzira ruoko rwakaipa kumusoro kuti ufambe iyo vhekita disc pasi kuzadzisa kuvharwa. Panguva ino, kusanganiswa kwemasimba matatu kunofanirwa kukurirwa, kureva:

1) axial kusundwa fa;

2) kupokana pakati pekurongedza uye vharuvhu stem fb;

3) Bata Friction FC pakati pevhu uye vharuvhu

Iyo huwandu hwenguva dziri σm = (fa + fb + fc) r

Inogona kuoneka kuti yakakura iyo yekubvisa diamita, iyo yakakura iyo inonhuwirira simba. Kana iri pedyo neiyo yakavharwa nyika, iyo axial yakakundwa simba iri pedyo nekumanikidzwa kweiyo pombi network (nekuda kweP1 - P2≈P1, P2 = 0)

Semuenzaniso, kana iyo DN200 yekumira vharuvhu rashandiswa pane 10bar pombi, chete chinhu chekutanga chinovhara chinongedzo chexping fa = Muganho wesimba, saka zvakaoma kwazvo kuti munhu mumwe chete arege zvachose vharuvhu mumamiriro ezvinhu akadaro.

Ehezve, mamwe mafekitori anoratidza kuti macves akadai anofanira kuiswa munzira yekudzoreredza, inogadzirisa dambudziko rekunetseka mukuvhara, asi dambudziko rekunetseka nekuvhurwa mushure mekuvharwa kwapera.

Kuongororwa kwezvikonzero nei kureba - Diameter Globe Mavharu mavharuvhu arikuwedzera kune yemukati kubhururuka

Harre - Diameter Kumira Mavharavira anowanzo shandiswa muBoiler Outlets, Main sub - Cylinders, Steam Main Mapipi, Etc. Izvi zvinzvimbo zvine matambudziko anotevera:

1. Uye zvakare, iyo boiler yekukwira kugona kugona kusakwanisa kuve 100%, iyo ichaita kuti mupinde mumubhadharo wekutora mvura, ayo anogona kukonzera kukuvadza uye kukuvadza kwekuvhara kune vhezheni kusimbisa.

2) Kune iyo yekuvhara - Bvisa vheji padhuze neiyo boiler uye subsam ichingopindirana nekupedza phenirs Zvishandiso zveAlkali zvichakonzera kuora uye kuumbwa kune chisimbiso pamusoro; Zvimwe zvinhu zvekristaro

3. Iyo vheti inosimbisa nzvimbo iyo inokonzera kukuvadza kwakadai sekuparadza nekukasira.

4. Nekudaro, muchimiro ichi, kuvhurika kweValve kunowanzove zvidiki kwazvo, zvichikonzera kuora kwemararamiro kuve kwakanyanya kupfuura kushanda kwakajairika, uye zvakanyanya kuderedza hupenyu hwebasa rekuisa chisimbiso.

Solutions yekuvhura yakaoma uye kuvhara kweakakura - Diameter Globe Mavharuvhu

1) Kutanga, inokurudzirwa kusarudza mabhebhi - Yakavharwa Svina - Bvisa Vharuvhu kuti udzivise kupokana kwekupokana kweVhebhu vakapfeka uye kurongedza vharuvhu uye ita kuti switch ive nyore.

2) iyo vheji core uye chigaro chinofanira kuve chakagadzirwa nezvinhu zvine midziyo yakanaka kupesana uye kupfeka zvivakwa, zvakadai sewete simented carbide.

3) Inokurudzirwa kutora maviri vheti yekuvhiringidzika kuti udzivise kuumbwa kwakawandisa nekuda kwekuvhura kudiki, iyo ichakanganisa hupenyu hwebasa uye chisimbiso. Kana zvavharwa, zvinogara zvichinge zvaonekwa kuti kuchave nekudzika, uye zvakaoma kuvhara. Chikonzero chedambudziko iri chinokonzerwa nechimiro chekugadzira vheji uye kushayikwa kwemunhu muganho wevanhu kubuda torque.
