Mune ichangoburwa hydraulic maintenance workshop, mumwe munhu akandibvunza maonero angu pamusoro pevharuvhu yekuzviparadzanisa papombi yekudyara mutsara uye kana zvichisungirwa kushandisa mavharuvhu ebhora anodhura kana achienzaniswa neanowanzo kuchipa mavharuvhu e butterfly. Mudzi wedambudziko iri uri mumhedzisiro yakaipa yemhirizhonga mumutsara wekusveta pombi. Nharo yekushandisa bhora revhavha sevhavha yekuzviparadzanisa yemutsara wekutora ndeyekuti kana bhoti yebhora yakavhurwa, gomba rose revhavha rinogona kushandiswa pakuyerera kwemafuta. Nokudaro, kana iwe ukaisa 2-inch ball valve mumutsara we 2-inch intake line, apo valve yakazaruka, ichaita seisipo (kunyanya kubva pakuona kwemafuta).
Kune rumwe rutivi, shavishavivharuvhu haina kuzara nemakomba. Kunyange kana yakazarurwa zvakakwana, chimiro cheshavishavi chicharamba chiri mugomba uye chinoratidza kurambidzwa kwechidimbu, izvo zvisingawanzoitiki. Izvi zvinogona kukonzera mhirizhonga, iyo inogona kukonzera mhepo yakanyungudika kutiza kubva mumhinduro mumutsetse wekutora. Kana izvi zvikaitika, mabhuru aya anoputika kana akafumurwa kudzvanywa papombi yekubuda. Mune mamwe mazwi, butterfly mavharuvhu anogona kukonzera cavitation.
Saka ndeipi yakanakisisa: vharafu yebhora kana butterfly valve? Zvakanaka, sematambudziko mazhinji ane hydraulics, zvinoenderana. Munyika yakanaka, ndinogara ndichisarudza vharafu yebhora pamberi pevhavhavhavhavha. Kune pombi yekupinza ine dhayamita yakawanda ye3 inches, pane inenge isina kurasikirwa kwemari mukuita kudaro.
Asi kana ukawana 4 inches, 6 inches uye 8 inches mudhayamita, mavharuvhu ebhora anodhura zvakanyanya kana achienzaniswa nemavharuvhu eshavishavi. Vanotorawo nzvimbo yakawanda, kunyanya pamusoro pehurefu hwose. Naizvozvo, mumashandisirwo emafoni, semuenzaniso, haisi iyo chete mutengo weiyo yakakura-dhayamita bhora vharafu inorambidza yakakwira, asi panogona kunge pasina nzvimbo yakakwana pakati petangi yekubuda uye pombi yekuisa kuti iise.
Pane yechitatu sarudzo. Vanhu vazhinji vanotenda zvisiri izvo kuti iyo yekutora mutsara yekuzviparadzanisa valve yakakosha, asi chaizvoizvo haisi, asi pane zvishoma.
Mubvunzo wekutanga unotevera nzira yekutsiva pombi kana pasina valve yekuzviparadzanisa pamutsetse wekutora. Pane mhinduro mbiri. Chokutanga pane zvose, kana pombi ine kukanganisa kwakashata uye basa rako "rakarurama", unofanira kushandisa ngoro yekusefa kuti utore mafuta kubva mutangi uye uidururire mubhaketi rakachena kana chimwe chigadziko chakakodzera. Zvadaro tangi yemafuta inofanira kucheneswa zvakakwana, pombi inofanira kuchinjwa, uye ipapo ngoro yefirita inofanira kushandiswa kupomba mafuta (uchifunga kuti ichiri kushandiswa) kudzokera kutangi.
Kupokana kwakawanda pane izvi ndeichi: Ha, hatina nguva yekuita izvi!q kana pHapana 10, 20, kana madhiramu akachena akawanda akatitenderedza.q Kune avo vasingade kuita basa rakanaka, imwe mhinduro ndeyekuisa. yese Permeate inovharirwa kumusoro kwenzvimbo yetangi yekuchengetera, uyezve yeindasitiri vacuum cleaner yakabatana kune tangi vent. Paunenge uchitsiva pombi, batidza vacuum cleaner, wozodzokorora oparesheni apo marara kubva pakutadza kwepombi yakambokonzeresa kuti pombi yekuchengetedza ikundikane.
Hongu, pane zvisizvo, sekukwevera pombi inodarika imwe kubva mutangi rimwe chete, kana kupomba mazana matatu emazana emafuta kubva mutangi hazvigoneke. Dzimwe nguva valve yekuzviparadzanisa yemutsara wekutora inodiwa. Kana izvi zviri izvo, zvine hungwaru kuve nechokwadi kuti vane maswiti epedyo kudzivirira kutanga pombi mushure mekuvhara vharuvhu.
Nzira yangu yandinofarira ndeyekusaisa mavharuvhu ebhora kana butterfly mavharuvhu, kana zvichibvira. Kana iwe uchifanira kuva neimwe, shandisa vheji yebhora kana mutengo kana nzvimbo isiri nyaya. Zvisinei, kana chimwe chezvinetso izvi chiri dambudziko, butterfly valve ndiyo chete sarudzo.
Mune akawanda maapplication, butterfly mavharuvhu anoshandiswa sepombi yekudyara yekuzviparadzanisa mavharuvhu. Makuru ma hydraulic excavator muenzaniso wakajairika. Vane pombi dzakawanda dzinosveta kubva mutangi guru kuburikidza nehombe-dhayamita yekutora mutsara, uye hapana nzvimbo yakawanda-zvose zvikamu zvisingabatanidzi sarudzo yakanakisisa (hapana vharafu kana vheji yebhora) isingabatanidzwi.
Ini handiyeuke ndichimboona pombi pane hombe ye hydraulic excavator isiri kukuvadzwa neinenge imwe cavitation erosion, mune iyo nyaya kukuvara uku kunogona kutariswa kupfeka kukuru. Ko uku kukuvadzwa kwecavitation kungave kwakakonzerwa nemhirizhonga yakakonzerwa nevhavhavhavhavha? Hongu zvinogona, asi pangava nezvimwe zvikonzero zvakawanda. Nzira chete yekuve nechokwadi 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. Rumwe ruzivo rwekudzikisa mitengo yekushandisa uye kuwedzera mitengo…
