Nekuti vharafu yechiteshi chemagetsi inoita basa risingadzokerike musimba rose remagetsi, zvinodikanwa kusarudza vharuvhu ine mhando yepamusoro uye yakagadzikana kuita. Nekudaro, mukushandiswa chaiko kweiyo nzira yevhavha, kuchine matambudziko mazhinji uye kukanganisa kweiyo magetsi chiteshi vharafu, mavharuvhu emhando yemhando haazadzise zvinodikanwa zveakakodzera zviyero uye zvakatemwa, iyo valve yekugadzira kushaya kwesainzi uye yakavimbika, simba. station valve control system inewo zvimwe zvikanganiso. Kuvapo kwematambudziko aya kunorambidza zvakanyanya kushandiswa kwemagetsi emagetsi mavharuvhu, nekudaro zvichitadzisa kuvandudzwa kwenguva refu uye kwakavimbika kweindasitiri yemagetsi. ? Kukuvadza kugedhi regedhi chikamu chakakosha chevhavhavha yegedhi, saka, kuitira kuti basa revhavha yegedhi riwane kutamba kunobudirira, zvakakosha kuisa kukosha kukuru pakusimwa kwayo, uye mukugadzirwa kana kuchengetedza kwezvikamu zvakakosha. . Mukuita kwekushandisa gondohwe, simba rinonyanya kutorwa kubva kune simba rekuita uye kumanikidza simba, uyezve, kune kukukurwa uye kukanganisa kunokonzerwa nemvura. Pamusoro pekuisa chisimbiso, iyo extrusion force uye friction force ndiyo inomanikidza. Dzvinyiriro yegedhi ndeyekusara kushushikana uye static kudzvanywa, uko kusara kunetseka kunokanganiswa nekugadzira zvinhu, static pressure inobatwa nevhavha chigaro uye mvura. Zvinoenderana nekuongorora kwesimba, kusiyana uye kuomarara ndiwo maitiro egondohwe, uye gondohwe richakuvadzwa kana raiswa mutoro unorema wekunze. Panguva imwecheteyo, pasi pesimba remasimba ose, mvura inosimbiswa, uye inobva yaora muviri wechisimbiso wegedhi, inoderedza chisimbiso chegedhi, iyo inotungamirira kukuvara kwegedhi. Kukundikana kwegadziriro Mutsaona yevhavha, nekuda kwevhavha yekudzora system kukundikana kunokonzerwa nenjodzi huru dzakaverengerwa chikamu chikuru. Kuburikidza nekutsvaga nekuongorora, kutadza kwehurongwa, kunyanya nekuda kwekushaikwa kwehungwaru uye nesainzi dhizaini yekuvhurwa kwevharuvhu, chimiro chekufambisa hachina kuchinjika zvakakwana, uye sitiroko haina kurongeka uye zvichingodaro, izvi ndizvo zvinhu zvakananga zvinokanganisa iyo valve control system kutadza. , kunyanya kukanganisa pakudengenyeka kwayo uye simba rinonyanya kuoneka. Valve yekuvhura dhizaini yakanyatso hukama nekurongeka kugadzirwa kwekugadzira, uye kutarisisa kwakanyanya kunofanirwa kubhadharwa kwairi. Parizvino, tsvakiridzo yekuvhura iri kuwedzera kunetsa, uye zvishoma nezvishoma inova dambudziko guru rekutsvaga. Munzira yekufambisa, nekuenderera mberi nekuvandudzwa kwesainzi uye tekinoroji, vharafu yakangwara inoiswa pamberi. Inogona kuziva chikamu chayo chehafu maererano nemamiriro akasiyana-siyana ekushanda, uye ine basa rekuzvitonga uye maitiro chaiwo-nguva, iyo inovimbisa kushanduka kwevhavha kusvika pamwero mukuru. Digital positioner ndiyo chikamu chekutanga chevhavhavha yakangwara, nerubatsiro rwemicroprocessor, kuvandudza kurongeka kwevhavha actuator positioning, uye valve ine chekuita ne data monitoring uye kurekodha. Mubvunzo wesimba Simba uye hupenyu hwebasa revhavha inotarirwa nehuwandu hwenguva iyo chikwata chinotanga, uye kukurumidza kutungamirirwa kwevhavha ndiyo inonyanya kutungamirira. Kuti uite kuti valve ishande, zvinodikanwa kuisa pfungwa pane simba, kusimba uye hupenyu hwebasa revhavha kuti uone. Kazhinji, kana chikwata chichiwanzotanga, valve haizokwanisi kuzadzisa zvinodiwa zvekushanda, izvo zvinonyanya kukonzerwa nekusakwana kwesimba revhavha. Mukugadzirwa kwevharuvhu, kuve yakavakirwa pamutoro wekutanga, mune yakarongeka dhizaini, chete teerera kune tembiricha, static kumanikidza uye zvinokambaira uye zvimwe zvinofurira zvinhu, hazvina kufunga nezve dambudziko rehupenyu hwekuneta, rinotungamira kune dhizaini yevhavha. haigone kusangana nezvinodiwa chaizvo zvekushandisa. Nokudaro, hupenyu hwekuneta hunofanira kuverengerwa mukugadzira kuti uone kuti chimiro chekugadzirisa chinopindirana nemamiriro ekushanda, kuitira kuti uwedzere hupenyu hwebasa revhavha. Tichifunga nezvemamwe matambudziko uye hurema huripo muvharuvhu yechiteshi chemagetsi, vashandi vakakodzera vakaita tsvakiridzo yakadzama uye ongororo, uye vakaisa kumberi kunoenderana kugadzirisa matanho. Panguva imwecheteyo, nzira yevhavha yechiteshi chemagetsi yakakurukurwa, iyo yakabatsira zvikuru kuti ive nechokwadi chekushandiswa kwakanaka kwevhavha yechiteshi chemagetsi. Nzira yekuchengetedza Kuti kuve nechokwadi chekuvimbika uye kuchengeteka kwevhavha yemagetsi mukushanda, inofanira kugara ichichengetwa kuti ive nechokwadi chekushanda kwemagetsi emagetsi nguva dzose. Kuburikidza nekuongorora uye kutsvagisa kwevashandi vakakodzera, nzira yekushandisa yevhavha inopfupikiswa, ndiko kuti, kushanda kwakachengeteka uye kurerutsa kugadzirisa, chete kuzadzisa zviyero zviviri izvi, kuve nechokwadi chekushanda kwevhavhavha yebasa, kuitira kuti uve nechokwadi chehutano uye hutano. kuvandudzwa kwakachengeteka kweindasitiri yemagetsi. Chidzidzo chedambudziko Maererano nekuongororwa kwemaitiro chaiwo ekushandiswa kwevhavha yemagetsi emagetsi, matambudziko makuru mukutonga, simba, uye vibration ndiyo valve. Kuburikidza nerondedzero iri pamusoro inozikanwa, magetsi echiteshi chevhavha matambudziko aripo mukusiyana uye kuoma, asi homogeneity, zvikonzero zvekuumbwa kwematambudziko aya kuitira kugadzirisa matambudziko aya, pesvedzero yevashandi vakakodzera vemagetsi chiteshi chevhavha * * * uye kuongororwa kwehurongwa, saka mhedzisiro yezvinetso zvevhavha ine kunzwisisa uye kugona. Pakati pavo, simba, static, simba, kupfeka kusagadzikana uye kugadzikana zvinhu zvinodzidzwa. Kutariswa kwevharuvhu Panguva ino yekugadziriswa kwedambudziko revhavha, kuvandudzwa kweiyo valve control system uye chaiyo-nguva yekutadza kuongororwa kune dzimwe nyika kwakatariswa, mumamiriro ezvinhu aya, nekuti vagadziri vevhavha vakaunza hupfumi hwakawanda, kuitira kusimudzira kukurumidza kusimudzira maindasitiri ane hukama. Nekuenderera mberi kwekuvandudzwa kwehunyanzvi hweruzivo rwemagetsi, indasitiri yemagetsi yenyika yedu inoshandisa tekinoroji yepamusoro yepamhepo, uye mamiriro ekushandiswa kwemavharuvhu ari kutarisisa zvine simba munguva chaiyo, nekudaro kuwana data rekushanda remavharuvhu. Panguva imwecheteyo, kushanda kwevhavha kunovandudzwa, nguva yekuchengetedza yevhavha inoderedzwa, mari yekuchengetedza inochengetwa, uye hupfumi hwehupfumi hunovandudzwa. Zvinogona kutaurwa kuti iyo inoshanduka yepamhepo yekutarisa mavharuvhu yakaisa hwaro hwakasimba hwekukurumidza kusimudzira kweindasitiri yevharuvhu, kuitira kuti igare ichienderana neyepasi rose tekinoroji level. Kuongororwa kweTekinoroji Ivhavha yemagetsi yemagetsi inonyanya kuzivikanwa nevevhavha disc kufamba, uye kufamba kune maitiro akasiyana, panguva imwe chete, gumbo revhavha rinovhura nekuvhara rine chirwere chipfupi, saka kuvimbika kwekucheka kwakakwirira. Iyo disc yeglobe valve inogadzirwa nesimbi yakakandwa kana simbi yakaumbwa. Kana dhisiki yakavhurwa, chigaro chevhavha uye chisimbiso chepamusoro che disc chichaparadzaniswa, kuitira kuti kupfekedzwa kwemagetsi kwechisimbiso kunenge kuduku uye nzvimbo yekuvhara ine pfuma yakanaka yekuvhara. Zvisinei, kukanganisa kwechisimbiso chepamusoro ndiko kusungirirwa kwezvikamu, uye diski yevhavha inoda kuitwa bhora reporcelain kana bhora resimbi. Kazhinji, dhisiki uye chigaro muvharuvhu yepasi zviri nyore kutsiva nekuchengetedza, uye vharafu uye pombi zvinogona kusungirirwa muchidimbu pasina disassembly yevhavha yese.
