Ona Mufananidzo Mukuru
Mavharuvhu anogadzirwa kuti agare kwenguva refu.Nekudaro, pane mamiriro ezvinhu ekuti mavharuvhu eindasitiri haagare nenzira yaanofanirwa kuita.Kuziva mamiriro aya kunogona kubatsira kurebesa hupenyu hwevhavha.Mukuwedzera, kugadziriswa kwevhavha chinhu chakakosha chehupenyu hwevhavha.
Kupfeka kwevhavha uye kubvaruka chinhu chinowanzoitika.Asi, nekumisikidzwa kwakanaka uye kugadzirisa, unogona kurebesa hupenyu hwako hwevhavha.Band-aid mhinduro haisi refu mhinduro kana zvasvika pakugadzirisa vharafu.
Kune nzira dzakawanda dzekuwedzera hupenyu hwebasa revhavha, zvinhu zvitatu zvakagara zvichiuya.Aya ndiwo maitiro ekusarudza, maitiro ekuisa uye maitiro ekugadzirisa.Kusarudza rudzi rwakafanira rwevharuvhu kwakakosha kune kutenderera kwehupenyu hwevharuvhu.Mamwe maviri anowedzera tarisiro yehupenyu hwevharuvhu.
Ichi chinyorwa chinokurukura nzira dzakasiyana-siyana dzekuwedzera hupenyu hwebasa remavharuvhu eindasitiri.
#1 Nzwisisa Mavharuvhu
Kune marudzi akawanda emavharuvhu mukuvhiya kumwe chete.Nhanho yekutanga mukuchengeta kutendeseka kwevharuvhu kuitira kuti iwe ugone kurebesa hupenyu hwayo kunzwisisa kuti imwe vharuvhu inoshanda sei.
Tarisa iyo XHVAL label pavharuvhu yako kuti uzive maratidziro evharuvhu, kusanganisira mhando yehurongwa iyo vharafu inofanira kushandiswa.Pamusoro pezvo, gara uchiverenga bhuku rinouya pamwe chete nevhavha kuti uzive kuti vharafu inogadzirwa nei, kudzvanywa uye tembiricha yemhando uye zvinoda.
Semuenzaniso, mavharuvhu ebhora anongoshandiswa pakuvhara kwakasimba.Gedhi vharafu ine throttling simba asi inowanzoitika kune friction.Butterfly mavharuvhu haaremi uye akanakira kutsaurwa nevezvenhau asi pane katsika kekuti substrates inoramba iri muvharuvhu.Ivhavha yekuyamura ingave sarudzo yakanaka yekupuruzira.
Chikamu chekunzwisisa vharafu yega yega kuziva kuiswa kwayo kwakaringana.Ziva kuti rudzii rwebore runofanira kushandiswa kuvhavha kana kumanikidzwa kuri kufunga kukuru.Ingave vharafu ichifanirwa kuvharwa, welded kana likes zvakare zvinhu zvikuru.Izvi zvinogona kureva kuvuza kunogona kuitika kana chisimbiso chakasimba.
Imwe yematambudziko kana iwe usingazivi nezvikamu zvevharuvhu, unogona kupedzisira waparadza valve nekuda kwekusaziva.Mumwe muenzaniso wakadaro kutendeuka kwekufamba kunomira pavharuvhu uye actuator.Kumira kwekufamba kunowanzoita semabhaudhi nenzungu.Izvi hazvifanirwe kubatwa nekuti izvi zvinoita kuti dhisiki risatenderera.
Nekudaro, nekuzvidzidzisa kuti mavharuvhu ekunze anotaridzika sei, uye kuziva panowanikwa mavharuvhu anogona kukuchengetedza kubva mukukuvadza mavharuvhu.
Mafungiro ehunyanzvi akadai sekumanikidza, mafambiro ekuyerera, tembiricha, pakati pezvimwe, zvakare chikamu cheiyo yekudzidza curve.Kuverenga iyo yakanakisa mashandiro poindi (BEP) inokupa iwe hunhu hunoshanda mavharuvhu pakunyanya kwayo.
#2 Ita shuwa Sarudzo Yekurudyi Yevhavha
Kusarudzwa kwevhavha kunogona kunge kwakaoma.Asi, nhanho iyi ndiyo nhanho yekugadzira-kana-kuputsa.Kana iwe ukanyora pamaitiro ekusarudza, unogona kusarudza vharafu isina kunaka.Izvi zvinogona kureva kurasikirwa kunogona kuitika.
Chimwe chezvikuru zvinokonzeresa kuvuza ndiyo dhizaini isiriyo yevharuvhu kana zvinhu zvine chekuita nenhepfenyuro.Mukufamba kwenguva, valve isina kururama yaizorasikirwa nekushanda kwayo kwakakwana.Izvozvo zvingareva kurasikirwa kwauri.
Zvaunofanira kuita kuziva mhinduro dzemibvunzo iyi:
1.Ndeipi chimiro chenhepfenyuro?
2.Ndeipi tembiricha yemhando yenhau?
3.Ndeipi iyo yekumanikidza siyana yevezvenhau?
4.Ivhavha ichange iri panzvimbo yakazaruka here kana kuti ichavharwa nguva dzose?
Kuti udzivise kutorwa mazwi evharuvhu isiriyo nevagadziri vevharuvhu, gara uchiongorora maratidziro evharuvhu uye gara uchibvunza mibvunzo yakakodzera.
#3 Ita shuwa Kuiswa Kwakakodzera
Kuiswa kwakakodzera kunotanga mukuchengetedza mavharuvhu mushure mekunge aya aendeswa.Mavharuvhu anogona kuwana kukuvadzwa kubva mukuora kunokonzerwa nekuregeredza, kunyanya kana mavharuvhu akasiiwa asina kufukidzwa mumhepo.
Imwe nyaya inowanzoitika pakati pevagadziri vevharuvhu ndeyekubviswa kwemavharuvhu ekupedzisira anoita sechidziviriro chemukati mavharuvhu.Kana izvi zvabviswa, mikana iripo, miviri yekunze inogona kupinda mukati mevhavha.Izvi zvinogona kukonzera kukuvadzwa kwezvigaro kana valve yatanga kushanda.Kana zvigaro zvakuvadzwa, pane mukana wepamusoro wekudonha.
Uyezve, valve inofanira kuongororwa zvakakwana isati yaiswa kune system.Izvi ndezvekuona kuti muviri uye zvikamu hazvina kukuvara panguva yekutumira.
#5 Vachenese
Kuti mavharuvhu agare kwenguva yakareba, zvakakosha kuti aya anofanira kucheneswa kamwechete pagore kana kana zvichidiwa, kunyanya kana nzvimbo yechirimwa yakasviba.Shandisa midziyo yakakodzera yakaita sejira, mafuta ekuzora kana mabhurashi ewaya kuchenesa muviri wevharuvhu uye zvinhu zvakaita seshinda, matanda, nzungu nezvimwe zvinoda.
Izvo zvakakoshawo kuti mavharuvhu acheneswe zvakanaka asati aaisa kune pombi system.Nenzira iyi, mavharuvhu haana zvinosvibisa zvinogona kukuvadza kwete vharafu chete asiwo midhiya inoyerera nemairi.
#6 Vapfekedze
Mune mamwe maapplication ane corrosive media kana ayo maapplication anoda high pressure uye tembiricha, kupfekedza mavharuvhu nemafuta ekuputira kunogona kuwedzera hupenyu hwesevhisi yemavharuvhu.Thermal coatings inofanira kushandisa high-velocity oxy-fuel process sezvo izvi zvakaratidzwa kuva zvakakura mukuputira mavharuvhu.
#7 Kugara Kuongororwa
Chokwadi, mavharuvhu anofanirwa kuongororwa nguva nenguva.Kunyange zvazvo basa iri richigona kunetesa, rinotofanira.Kune mavharuvhu ebhora uye mamwe mavharuvhu ane hukama, nekuita kudaro, uri kuona kuti mavharuvhu haana kukuvara uye achiri kuchengetedza yakasimba shutoff.Mavharuvhu ekupuruzira anoda kutariswa kukuvara kwefriction
Sekutonga kwechigunwe, mavharuvhu anoshandiswa nesimba anofanirwa kutsiviwa mukati memwedzi mitanhatu yekushandiswa.Zvisinei, pakushanda kwakakosha, mavharuvhu anofanira kuongororwa mwedzi mitatu yega yega.Kuongorora kwakadai kunofanirwa kusanganisira kutarisa kuti panobuda mvura here, corrosion uye nhengo dzakaremara.
Panguva yekuongorora nguva dzose waiwana pakatsemuka, kucheka uye kunyange kudonha pavharuvhu.Zviitiko zvakadaro zvinowanzoitika kana mavharuvhu achiwanzo shandiswa nekufamba kwenguva.
#8 Kudzivirira Maintenance
Kana mavharuvhu asingadziviriri, shandisa zvigadzirwa zvinofanirwa kudzivirira kutanga kwekuora kunogona kukanganisa valve.Kushandiswa kwakapfava pamwedzi kwechizoro chechinangwa chakajairwa kunogona kuita zvishamiso uye zvinogona kuwedzera hupenyu hwevharuvhu.Nekudaro, cherechedza mafuta ekushandisa sezvakakurudzirwa nevagadziri vevharuvhu.
Pamusoro pezvo, kuchengetedza kwekudzivirira kunofanirwa kutanga nekuita shuwa kuti zvinhu zvinoshandiswa mukugadzira vharafu zvinofanirwa kuenderana neyakatsanangurwa pepa rakapihwa kune yekupedzisira-mushandisi.Zvakare, sechikamu chekuchengetedza kuchengetedza ndeyekuita chokwadi chekuti mavharuvhu anogara achizorwa.
Panofanira kuitwa ongororo dzenguva dzose kuitira kuti pave nekukasika kuonekwa kwezvingabvira zvinobvinza uye zvinodaro.Kunyange izvi zvichionekwa sekuita kunodhura, imwe yedzakanakisa nzira dzekuwedzera hupenyu hwemavharuvhu eindasitiri ndeyekuita bvunzo dzekuvuza.
#9 Munda Machining
Kana mavharuvhu achishandiswa kakawanda, simba rekuvharisa rezvisungo rinopera.Kuve nechokwadi chekuti mavharuvhu haadonhe paflange pasina kubvisa vharafu kubva muhurongwa, machining emunda anoshandiswa.
Muchidimbu
Nokudzidza chimiro chevhavha chaiyo, kuchenesa valve uye kuita kudzivirira kuchengetedza, pakati pevamwe, kunogona kuwedzera hupenyu hwemaindasitiri mavharuvhu.Kana iwe uchida kudzidza zvakawanda nezve mavharuvhu eindasitiri, inzwa wakasununguka kutibata nesu.
