Pakati pevashandisi vanoshandisa mavharuvhu eglobe ane dhayamita yakakura zuva nezuva, vanowanzo taura nezvedambudziko rekuti mavharuvhu eglobe ane dhayamita yakakura anowanzo kuve akaoma kuvhara kana achishandiswa mumidziyo ine musiyano mukuru wekumanikidzwa, senge utsi, mvura ine pressure yakakwira, nezvimwewo. Pakuvhara nesimba, zvinogara zvichionekwa kuti panenge paine kubuda kwemvura, uye zvakaoma kuvhara zvakasimba. Chikonzero chedambudziko iri chinokonzerwa nekugadzirwa kwevharuvhu uye torque yakakwana yekubuda kwehuwandu hwemunhu.

Kuongororwa Kwekuoma Kwekuchinja Mavharuvhu Akakura

Simba remunhu mukuru rinosvika 60-90kg, zvichienderana nemuviri wake.

Kazhinji, nzira yekuyerera kwevharuvhu yepasi yakagadzirwa kuti ive yakaderera mukati nekunze. Kana munhu akavhara vharuvhu, muviri wemunhu unosunda vhiri reruoko kuti ritenderere rakatwasuka, kuitira kuti vharuvhu rifambe richidzika kuti rivhare. Panguva ino, zvinodikanwa kukunda musanganiswa wemasimba matatu, anoti:

(1) Simba rekusundidzira reAxial Fa;

(2) Simba rekukweshana Fb pakati pekurongedza ne vharuvhu;

(3) Simba rekukweshana kwekubatana Fc pakati pehunde yevharuvhu nepakati pedhisiki revharuvhu

Huwandu hwenguva ndi ∑M=(Fa+Fb+Fc)R

Zvinogona kuonekwa kuti kana dhayamita yakakura, simba rekusunda re axial rinokurawo. Kana riri pedyo nemamiriro akavharwa, simba rekusunda re axial rinosvika pedyo nekumanikidzwa chaiko kwenetwork yepombi (nekuda kweP1-P2≈P1, P2=0)

Semuenzaniso, vharuvhu yeDN200 caliber globe inoshandiswa papombi yesteam ye10bar, chete axial thrust yekutanga yekuvhara Fa=10×πr2=3140kg, uye simba rakatenderera rakatenderera rinodiwa pakuvhara riri pedyo nesimba rakatenderera rakatenderera iro miviri yevanhu inogona kuburitsa. Simba iri rinoita kuti zvive zvakaoma kuti munhu mumwe chete avhare vharuvhu zvizere mumamiriro ezvinhu aya.

Ehe, mamwe mafekitori anokurudzira kuisa mavharuvhu akadaro nekudzoka shure, izvo zvinogadzirisa dambudziko rekuoma kuvhara, asi panewo dambudziko rekuti zvakaoma kuvhura mushure mekuvhara.

Kuongororwa kweZvikonzero zveKubuda kweMavharuvhu eGlobe eDiameter Yakakura Mukati

Mavharuvhu epasi ane dhayamita hombe anowanzo shandiswa mumaboiler outlet, main cylinders, steam mains nedzimwe nzvimbo. Nzvimbo idzi dzine matambudziko anotevera:
(1) Kazhinji, musiyano wekumanikidzwa panzvimbo yekubuditsa bhoyira wakakura, saka mwero wekuyerera kwemhepo wakakurawo, uye kukuvara kwevhu panzvimbo yekuvharira kwakakurawo. Pamusoro pezvo, kushanda zvakanaka kwebhoyira hakugone kuva 100%, izvo zvichaita kuti mhepo iri panzvimbo yekubuditsa bhoyira ive nemvura yakawanda, izvo zvinozokonzera nyore nyore kukuvara kwekuvhara vharuvhu nekuvharira kukuvara panzvimbo yekuvharira vharuvhu.

(2) Pavharuvhu yekumisa iri pedyo nepanobva bhaira ne sub-cylinder, nekuti utsi huchangobva kubuda mubhaira hune chiitiko chekupisa kwakanyanya, panguva yekuzara kwayo, kana kunyorovesa kwemvura yebhaira kusina kunaka, chikamu chemvura chinowanzo kurutsa. Asidhi nealkali zvinokonzera ngura nekukukurwa kwenzvimbo yekuvhara; zvimwe zvinhu zvinokwanisa kufukidza zvinogonawo kunamatira pamusoro pevharuvhu uye kuita crystallize, zvichikonzera kuti vharuvhu isakwanise kuvharwa zvakasimba.

(3) Pamavharuvhu ekupinda nekubuda emasilinda epasi, kushandiswa kwemhepo mushure mevharuvhu kwakakura uye dzimwe nguva kudiki nekuda kwezvinodiwa pakugadzira nezvimwe zvikonzero. Zvinokonzera kukurwa, kuvhurika kwevhuruvhu uye kukuvara kumwe pamusoro pevharuvhu.

(4) Kazhinji, kana pombi yakakura yakavhurika, pombi inofanira kupiswa, uye maitiro ekupisa pakutanga anoda kuti mvura ipfuure nepakati, kuitira kuti pombi ikwanise kupiswa zvishoma nezvishoma uye zvakaenzana kusvika pamwero wakati vharuvhu yekumisa isati yavhurwa zvizere kudzivirira kukanganisa pombi. Kupisa nekukurumidza kunokonzera kuwedzera kwakanyanya, izvo zvinokuvadza zvimwe zvikamu zvekubatanidza. Zvisinei, mukuita uku, kuvhura kwevharuvhu kunowanzova kudiki, izvo zvinoita kuti mwero wekukurwa kwevhu uve wakakura kupfuura wekushandiswa kwakajairika, uye zvinoderedza zvakanyanya hupenyu hwebasa repamusoro pevharuvhu.

Mhinduro dzeMatambudziko eKuchinja Mavharuvhu Eguru reDiameter

(1) Chekutanga, zvinokurudzirwa kusarudza vharuvhu yeglobe yakavharirwa nebellows, iyo inodzivisa kukanganiswa kwekudzivirira kwekukweshana kwevharuvhu yeplunger nevharuvhu yekurongedza, uye inoita kuti switch ive nyore.

(2) Chigaro chevharuvhu nechigaro chevharuvhu zvinofanira kugadzirwa nezvinhu zvine simba rekudzivirira kukurwa kwevhu uye kushanda zvakanaka, zvakaita seStellite carbide;

(3) Zvinokurudzirwa kushandisa dhizaini yedhisiki ine mavharuvhu maviri, iyo isingazokonzere kukanganiswa kwakanyanya nekuda kwekuvhurika kudiki, izvo zvinokanganisa hupenyu hwebasa uye kushanda kwekuvhara.
