Nzira yekushanda nekuchengetedza valve panguva yekushanda, uye ndeipi mitemo inofanira kushanda nekugadzirisa kwevhavha kutevedza

Mazhinji mainjiniya e hydraulic ane hunyanzvi mukugadzirisa kwezuva nezuva kwevharafu mukati mekushanda, uye pane zvinenge zvisina kukanganisa, asi vanowanzofuratira zvinetso zvinogona kuitika zvevhavha mubasa rekushanda. Nzira yekushanda uye kuchengetedza valve mukushanda? Ndeipi mitemo inofanirwa kushanda uye kuchengetedza mavharuvhu kutevedzera? Sevharuvhu anovapindura mumwe nemumwe!

1,Maitiro ekushanda uye kuchengetedza valve panguva yekushanda

① Chengetedza zvikamu zvekunze uye zvinofamba zvevhavha yakachena uye chengetedza kuvimbika kwepende yevhavha. Iyo trapezoidal tambo, stem nut, inotsigira inotsvedza zvikamu, giya, worm uye zvimwe zvikamu pamusoro pevhavhavha, dzinde uye stem nati zviri nyore kuisa huwandu hwakawanda hweguruva, tsvina yemafuta, masara epakati uye imwe tsvina, zvichikonzera kupera uye kuora vharafu.

Nokudaro, chengetedza valve yakachena nguva dzose. Iyo huru huru pavharuvhu yakakodzera kucheneswa kwebhurashi uye kuchenesa mweya wakatsikirirwa, kunyangwe nemhangura waya bhurashi kusvika iyo yakagadzirwa nemichina ichiratidza simbi inopenya, uye pendi yependi inoratidza iwo chaiwo ruvara rwepende.

Muteyo weutsi uchave uri mukutonga kwemunhu akasarudzika uye kuongororwa kamwechete pashift; Vhura vharuvhu yekugezesa uye tepi yeutsi nguva nenguva, kana kusunungura uye kupuruzira nguva nenguva kudzivirira tsvina inovharira vharafu.

② Chengetedza mafuta evharuvhu, tambo yevharuvhu, stem nati uye tsigiro inotsvedza zvikamu, inotakura chinzvimbo, giya uye worm meshing zvikamu uye zvimwe zvinoenderana zvinofamba zvikamu. Mamiriro akanaka ekuzora anodiwa kuti uderedze kupokana uye kudzivirira kupfeka. Kune zvikamu zvisina kapu yemafuta kana muromo zviri nyore kukuvara kana kurasika panguva yekushanda, masisitimu ese ekuzora anozogadziriswa kuti ave nechokwadi chekudonhedzwa kwedunhu remafuta.

Iyo lubrication chikamu ichazadzwa nguva nenguva zvichienderana nemamiriro chaiwo. Kana iyo inowanzovhurwa, vheji yepamusoro yekushisa inokodzera kuwedzera kamwe pavhiki kusvika pamwedzi; Kana iyo isina kuvhurwa kazhinji, iyo refueling cycle yepasi-tembiricha valve inogona kureba. Mafuta ekuzora anosanganisira mafuta, bota, molybdenum disulfide uye graphite. Injini yemafuta haikodzeri kukwirisa tembiricha mavharuvhu; Butter haina kukodzera kana. Icharasika nekuda kwekunyunguduka pakupisa kwakanyanya. Ivhavha yekushisa yakakwirira yakakodzera kuwedzera molybdenum disulfide uye kupukuta graphite powder.

Kana zvikamu zvakafumurwa zvekuzora, senge trapezoidal tambo, pakati pemeno, nezvimwewo, zvichishandiswa negirizi, zviri nyore kusvibiswa neguruva. Kana molybdenum disulfide uye graphite poda inoshandiswa pakuzora, hazvisi nyore kusvibiswa neguruva, uye iyo lubrication effect iri nani pane bhotela. Graphite powder haisi nyore kushandisa zvakananga. Inogona kusanganiswa kuita paste nemafuta mashoma kana mvura.

Iyo plug valve ichazadzwa nemafuta panguva yakatarwa, zvikasadaro zviri nyore kupfeka uye kubuda.

③ Chengetedza zvidimbu zvese zviri zviviri. Mabhaudhi eflange nerutsigiro achave akasimba uye haazosununguke. Kana iyo yekusimbisa nati pavhiri reruoko yakasununguka, ichasimbiswa nenguva kuti isapfeke chibatanidzwa kana kurasikirwa nevhiri reruoko.

Gumbo reruoko harizorasikike uye kuchinjwa nenguva. Iko kurongedza kusiyanisa kudzvanywa hakuzorerekera kana kuve kusina preload clearance. Munharaunda yakasvibiswa nyore nyore nemvura, chando, guruva, nezvimwewo, tsvimbo yevhavha ichave yakagadzirwa nevhavha yekudzivirira. Mutongi ari pavharuvhu achave akakwana uye akarurama. Chisimbiso chinotungamira, chivharo uye pneumatic accessories zvevharuvhu zvichave zvisina kusimba. Iyo insulating jacket ichave isina kushushikana uye kutsemuka.

Mukuwedzera, hazvibvumirwi kugogodza valve, kutsigira zvinhu zvinorema kana kumira vashandi kuti varege kusvibisa valve uye kukuvadza valve. Kunyanya, kwete-metal mesh uye cast iron valves zvinorambidzwa.

Chengetedza kuchengetedza kwezuva nezuva kwemidziyo yemagetsi. Kugadziriswa kwemagetsi emagetsi kunowanzova kwete pasi pekamwe pamwedzi. Zvinyorwa zvekuchengetedza zvinosanganisira: kuonekwa kuchave kwakachena pasina kuunganidza guruva, uye midziyo haifaniri kusvibiswa nemhepo, mvura nemafuta; Nzvimbo yekuisa chisimbiso nemapoinzi zvichave zvakasimba uye zvakasimba. No leakage;

Chikamu chekuzora chichazadzwa nemafuta maererano nemitemo, uye nut yevhavha ichazadzwa nemafuta; Chikamu chemagetsi chichave chakasimba pasina kutadza kwechikamu, iyo otomatiki switch uye thermal relay haifanirwe kuvharwa, uye mwenje wechiratidzo ucharatidzwa nemazvo.

2,Ndeipi mitemo inofanirwa kushanda uye kuchengetedza mavharuvhu kutevedzera

Kugadziriswa uye kutariswa kwemavharuvhu kunoenderana nezvinodiwa zvinotevera:

1. Iyo yekubatsira solenoid valve yevhavha yesango rinonaya ichaongororwa mwedzi wega wega uye ichave pasi pekuedzwa kwekutanga. Kana chiito chisina kujairika, chinotsiviwa nenguva;

2. Simba rekupa uye kuzarura nekuvhara kushanda kwevhavha yemagetsi uye solenoid valve ichaongororwa mwedzi woga woga;

3. Mavharuvhu ekudzora ese ari pahurongwa achagadziriswa munzvimbo yakazaruka kana yakatsanangurwa ine zvisimbiso zvinotungamira kana maketani. Zvisimbiso zvinotungamirira nemaketani zvichaongororwa kamwe chete pamwedzi. Muchiitiko chekukuvara kana kukanganisa, ivo vachagadziriswa uye vanotsiviwa nenguva;

4. Ivhavha yekudzivirira muvharuvhu yekunze uye papombi yemvura inopinza ichaongororwa kamwe chete pakota, uye ichaonekwa kuti yakazaruka zvakakwana;

5. Kuonekwa kwevharuvhu yekudzivirira kwemvura uye boka revharuvhu yearamu ichaongororwa zuva rega rega, uye hurongwa huchave husina kukanganisa;

6. Muedzo wekuyerera kwemvura uchaitwa kune ese ekupedzisira mavharuvhu ekuyedza emvura uye mavharuvhu ekuyerera emvura evhavha yearamu yegadziriro kota yega yega, uye kana kutanga kwehurongwa, basa rearamu uye mamiriro ekubuda kwemvura zvakajairika zvichaongororwa;

7. Kana mavharuvhu ekupa mvura yemunisiparati akazaruka zvizere, kudzvanyirira kweanodzivirira kubuda kwemvura kunoyedzwa mwedzi wega wega, uye kunoenderana nezvinodiwa zvezviyero zvepasirese zvazvino: kudzvanya kudzikisa backflow kudzivirira GB / T 25178, kuderera kwekushomeka kwekudzoka. mudziviriri JB / T 11151 uye kaviri cheki vharafu backflow kudzivirira CJ / T 160.
