Hupenyu hwesevhisi hwemavharuvhu eshavishavi hurefu hwakadini?

Hupenyu hwebasa rebutterfly mavharuvhuinokanganiswa nezvinhu zvakawanda zvakapindirana, kazhinji zvichichinja mukati memakore mashanu kusvika makumi maviri. 

Kutonga kwakananga kunoda kuitwa zvichibva pane zvinhu, mamiriro ekushanda, frequency yekushanda, uye nhanho yekuchengetedza. Musiyano wehupenyu hwepakati unokonzerwa nemisiyano yekugadzira mukuisa chisimbiso mavharuvhu: akapfava akavharidzirwa butterfly mavharuvhu anovimba nezvinhu elastic senge rabha kana polytetrafluoroethylene kuwana chisimbiso. Kunyangwe zvinhu izvi zvine mashandiro ekuisa chisimbiso akanakisa, anowanzo kukwira uye kuchembera kana akaiswa pasi pekumanikidzwa kwepakati, shanduko yetembiricha, uye kuvhurika nekuvhara kazhinji, zvichikonzera deformation kana kuputika kwechisimbiso chepamusoro. Semuenzaniso, pasi pekushisa kwemazuva ose uye mamiriro emvura yakachena, iyo yakapfava yakavharwa butterfly valve inogona kuvhurwa uye yakavharwa kanopfuura 50000 nguva, nehupenyu hunosvika makore mashanu kusvika ku8; Kana yakashandiswa mudhizaini yekufambisa ine granular media, kukukurwa kwechikamu kunomhanyisa kupera kwenzvimbo yekuvharisa, uye hupenyu hwesevhisi hunogona kupfupikiswa kusvika kumakore matatu kusvika mashanu. Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharuvhuvhu inotora simbi kusvika kusimbi chisimbiso (sesimbi isina tsvina,chromium molybdenum simbi), uye kusapfeka kwayo kunonatsiridzwa newelding hard alloy kana spraying wear-resistant coating. Yayo matatu eccentric chimiro inowana isina friction yekuvhura uye yekuvhara maitiro kuburikidza nematatu-dimensional offset yeaxis, cone pamusoro uye nzvimbo yekubata, zvakanyanya kudzikisa chiyero chekupfeka. Mupamusoro-tembiricha uye yakakwirira-kudzvanywa kwemhepo mapaipi, kuvhura uye kuvhara nguva dzevhavhavhavhavha yakavharwa yakaoma inogona kudarika 100000 nguva, uye hupenyu hwavo hunogona kusvika makore gumi kusvika makumi maviri; Kana iyo yepakati iri yakanyanya corrosive kemikari mhinduro, inodzivirira corrosion zvinhu zvakaita seHastelloy zvinofanirwa kushandiswa. Kunyangwe hupenyu hunogona kupfupikiswa zvishoma nekuda kwekushomeka kwemitengo yezvinhu, hunogona kushanda zvakatsiga kwemakore masere kusvika gumi nemashanu.

Mamiriro ekushanda ndechimwe chinhu chakakosha chinotarisa hupenyu hwebutterfly mavharuvhu. Mune midhiya yakachena, nharaunda dzakapfava, uye yakaderera-frequency maitiro ekushanda, zvikamu zvevharuvhu zvinoiswa pasi pesimba rakafanana, nekupfeka kushoma mwero uye hupenyu hunowanzo kusvika painogumira dzidziso. Semuenzaniso, mumaguta ekugovera mvura, mavharuvhu akavharidzirwa akavharwa anogona kuvhurwa uye kuvharwa zvisingasviki ka5 pazuva, uye nekuchengetedza kwakakodzera, hupenyu hwavo hunogona kusvika makore masere kusvika gumi. Kusiyana neizvi, mumamiriro ezvinhu akaomarara ekushanda akadai sesimbi nemakemikari engineering, tembiricha yepamusoro (inopfuura 400 ℃), kudzvanywa kwepamusoro (kupfuura 10MPa), kusimba kwakasimba (senge acid-base mhinduro), kana kupfeka kwakanyanya (senge slurry nemadota) midhiya inogona kukurumidza kuchembera kwezvinhu uye kukuvadzwa kwechimiro. Semuyenzaniso, mumoto unoputika gasi pombi yechirimwa chesimbi, vharuvhu yeshavishavi yakaoma yakavharwa inoda kushingirira tembiricha yepamusoro ye800 ℃ uye kupeperetswa kwemhepo ine huruva. Kunyangwe neceramic coating chengetedzo, hupenyu hwayo hwesevhisi hunogona kungochengetwa kwemakore mashanu kusvika masere.

Mhedzisiro yemaitiro ekushanda uye nhanho yekuchengetedza pahupenyu haigone kuregererwa. Kugara kuvhurika nekuvhara (kanopfuura ka10 pazuva) kunogona kuwedzera kupfeka pazvinhu zvinotapurirana senge valve stems uye mabearings, zvichikonzera kuwedzera kuvhura uye kuvhara torque uye kunyange jamming; Kukundikana kuchengetedza maererano nezvinodiwa (zvakadai sekusagara uchizora kana kuchenesa tsvina panzvimbo yekuisa chisimbiso) ichakurumidza kukwegura kwezvisimbiso uye kupfupisa hupenyu hwose hwevhavha. Semuenzaniso, mune imwe makemikari chirimwa, kutadza kugara uchitsiva chigaro chevhavha chisimbiso mhete kwakaguma nekudonha kwakanyanya kwevhavha mushure memakore matatu ekushanda, nepo vharafu inochengetwa maererano nemirairo pasi pemamiriro ekushanda akafanana inogona kuva nehupenyu hunosvika makore gumi nemaviri. Naizvozvo, kusarudzwa zvine musoro, kushanda kwakamisikidzwa, uye kugadzirisa nguva dzose ndiwo mazano makuru ekuwedzera hupenyu hwesevhisibutterfly mavharuvhu.
