Mune imwe nguva ichangoburwa hydraulic repair shop, ndakabvunzwa zvandinofunga pamusoro pevharuvhu yekuzviparadzanisa papombi yekusveta mutsara uye kana zvakakosha kushandisa bhora rinodhura rinodhura panzvimbo pevhavhavhavhavhavhavhavha inodhura. Mudzi wedambudziko iri uri mumhedzisiro yakaipa yemhirizhonga mumutsara wekusveta pombi. Nharo yekushandisa bhora revhavha sevhavha yekuzviparadzanisa yepombi yekupinza ndeyekuti kana yavhurwa, bhomba rakazara revhavha rinobvumira mafuta kuyerera. Nokudaro, kana iwe ukaisa 2-inch ball valve mumutsara we 2-inch intake line, kana valve ichizarura, ichaita sekuti haipo zvachose (kunyanya kubva pane imwe nzvimbo yemafuta).
Ukuwo, butterfly mavharuvhu haana kuzara. Kunyange kana yakazarurwa zvizere, shavishavi rinoramba riri mugomba uye rinoratidza kurambidzwa kwezvimiro zvisina kurongeka. Izvi zvinokonzera mhirizhonga, iyo inokonzera mhepo yakanyunguduka kuti ibude kunze kwekugadzirisa mupombi yekupinza. Kana izvi zvikaitika, mabhuru aya anoputika kana kudzvanywa kuchiiswa pombi yekubuda. Mune mamwe mazwi, butterfly mavharuvhu anogona kukonzera cavitation.
Saka ndeipi yakanakisisa: vharafu yebhora kana butterfly valve? Zvakanaka, sematambudziko mazhinji mu hydraulic system, zvinoenderana. Munyika yakakwana, ndinogara ndichisarudza mavharuvhu ebhora pamberi pemavharuvhu eshavishavi. Pamapombi ekudya anosvika masendimita matatu mudhayamita, panenge pasina kurasikirwa kwemutengo kuita kudaro.
Zvisinei, paunopinda 4 inch, 6 inch, uye 8 inch dhayamita, mavharuvhu ebhora anodhura zvakanyanya kana achienzaniswa nemavharuvhu eshavishavi. Vanotorawo nzvimbo yakawanda, kunyanya pakureba kwese. Nokudaro, semuenzaniso, mumashandisirwo emafoni, kwete chete mari yevhavha yakakura-caliber bhora inogona kunge yakanyanyisa, asi pangave pasina nzvimbo yakakwana pakati pematangi ekubuda uye pombi yepombi kuti iise.
Pane yechitatu sarudzo. Vanhu vazhinji vanotenda zvisiri izvo kuti iyo yekupinda pombi yekuparadzanisa valve yakakosha, asi chaizvoizvo haisi, asi pane zvishoma chete.
Mubvunzo wekutanga unobuda mukupindura dambudziko iri nderekuti ungatsiva sei pombi kana pasina vharafu yekuzviparadzanisa pamutsara wekutora. Pane mhinduro mbiri kune izvi. Chekutanga, kana pombi ikakundikana zvine njodzi uye uri kuita “chakanaka”, unofanira kushandisa ngoro yekusefa kudhonza mafuta kubva mutangi woiisa mubhaketi rakachena kana chimwe chigaba chakakodzera. Tangi yemafuta inofanira kubva yacheneswa zvakakwana, pombi inofanira kutsiviwa, uye ngoro yekusefa inofanira kushandiswa kupomba mafuta (kuchifunga kuti achiripo) kudzokera kutangi.
Kupokana kwakawanda pane izvi ndeichi: Ha, hatina nguva yekuita izvi!q kana pHatina gumi, 20, kana akawanda madhiramu akachena.q Kune avo vasingade kuti basa riitwe nemazvo, mhinduro imwe ndeyeSima zvese. zvikamu zvinopinda mukati metangi yepamusoro nzvimbo, uye batanidza iyo yeindasitiri vacuum cleaner kune inopindika chikamu chetangi yekufema. Batidza vacuum cleaner paunotsiva pombi, wozodzokorora chiitwa apo marara kubva pakutadza kwepombi yekupedzisira kwakaita kuti pombi yekutsiva itadze.
Chokwadi, pane anosiiwa. Semuenzaniso, kana paine mapombi akawanda anoyamwa kubva mutangi rimwechete, kana kupomba 3,000 marita emafuta kubva mutangi hazvigoneke. Dzimwe nguva pombi yekupinza yekuparadzanisa valve inodiwa. Kana izvi zviri izvo, zvine hungwaru kuve nechokwadi kuti vane maswiti epedyo kudzivirira pombi kubva pakutanga kana vharuvhu yakavharwa.
Kana zvichibvira, nzira yandinofarira ndeyekuisa kana vharafu yebhora kana butterfly valve. Kana iwe uchifanira kuva neimwe, kana mutengo kana nzvimbo isiri nyaya, shandisa vharafu yebhora. Zvisinei, kana pane dambudziko kune chero ipi zvayo, ipapo butterfly valve ndiyo chete sarudzo.
Mune akawanda maapplication, butterfly mavharuvhu anoshandiswa sepombi inlet isolation mavharuvhu. Makuru ma hydraulic excavator muenzaniso wakajairika. Vane pombi dzakawanda dzekusveta kubva mutangi hombe kuburikidza nepombi yakakura yekudyara, uye hapana nzvimbo yakawanda-zvose zvinoumba zvisingabatanidzi sarudzo inodiwa (hapana vharafu kana vharafu yebhora).
Handiyeuke ndakamboona pombi pane hombe ye hydraulic excavator isina kana imwe cavitation kukuvara, iyo inogona kunzi yakajairika kupfeka mune iyi application. Uku kukuvadzwa kwecavitation nekuda kwemhirizhonga inokonzerwa nevhavhavhavhavha? Hongu zvinogona, asi zvimwe zvakawanda zvinogona kukonzera. Nzira chete yechokwadi ndeyekuenzanisa mapombi maviri anoshanda pasi pemamiriro akafanana-imwe ine butterfly valve uye imwe isina butterfly valve.
Brendan Casey ane anopfuura makore makumi maviri echiitiko mukugadzirisa, kugadzirisa uye kugadzirisa nharembozha uye maindasitiri michina. Ruzivo rwakawanda nezve kudzikisa mitengo yekushandisa uye kuwedzera…
