Mhosva yekuongorora uye yekudzivirira kuchengetedza nzira yemagetsi flange globe mavharuvhu
Abstract: Sechikamu chakakosha chemaitiro ekudzora mvura, iyo yakachengeteka, yakavimbika, uye yakagadzikana mashandiro emagetsi flange globe mavharuvhu anokanganisa zvakananga kushanda kwakajairwa kwehurongwa hwese. Nekudaro, mumashandisirwo anoshanda, magetsi flange eglobe mavharuvhu anogona kusangana nekusashanda kwakasiyana kunokanganisa mashandiro avo uye hupenyu hwesevhisi. Ichi chinyorwa chinoongorora kutadza kuongororwa uye nzira dzekudzivirira dzekuchengetedza emagetsi flange eglobe mavharuvhu, nechinangwa chekupa ruzivo rwakakosha rweinjiniya nevashandi vehunyanzvi.
1,Nhanganyaya
Electric flange globe mavharuvhu anoshandiswa zvakanyanya mumaindasitiri akadai sepetroleum, makemikari, simbi, uye simba, ane hunhu hwechimiro chakareruka, kuita chisimbiso kwakanaka, uye kushanda kuri nyore. Nekudaro, panguva yekushanda kwenguva refu, nekuda kwezvikonzero zvakasiyana, mavharuvhu emagetsi eglobe emagetsi anogona kusangana nekukanganisa kwakadai sekudonha, kudhumhana, uye kusachinjika, zvichitungamira kumhedzisiro yakakomba sekuvhara kwemidziyo uye tsaona dzekugadzira. Naizvozvo, kugona kuongororwa kwekukanganisa uye nzira dzekudzivirira dzekuchengetedza emagetsi flange eglobe mavharuvhu zvakakosha zvikuru.
2,Mhando uye zvikonzero zvekukanganisa mumagetsi flange globe mavharuvhu
1. Leakage
Leakage ndeimwe yezvikanganiso zvinowanzoitika zvemagetsi flange globe mavharuvhu, uye zvikonzero zvikuru ndezvizvi:
(1) Pfeka kana kukuvadzwa panzvimbo yekuisa chisimbiso: Munguva yekushandiswa kwenguva refu, nzvimbo yekuisa chisimbiso inotapukirwa nekukukurwa kwepakati uye kupera, zvichikonzera kudzikira kwekuita chisimbiso.
(2) Filler kuchembera: Filler chinhu chakakosha kuti ive nechokwadi chekuisa chisimbiso chemagetsi flange eglobe mavharuvhu. Mushure mekushandiswa kwenguva refu, inowanzoitika kukwegura, kupfeka, uye kubuda.
(3) Valve body kana valve cover deformation: Nekuda kwezvinhu zvekunze senge tembiricha uye kudzvanywa, muviri wevharuvhu kana chivharo chevhavha chinogona kukanganisa, zvichikonzera kuwedzera kwepakati pakati pekuisa chisimbiso uye kukonzera kuvuza.
2. Yakanamira
Chiratidzo chikuru chemagetsi flange yekuvhara-vhavha jamming ndeyekuti valve haisi panzvimbo kana haigoni kuvhurwa nekuvharwa, uye zvikonzero ndezvizvi:
(1) Kukweshana pakati pehunde yevharuvhu nekurongedza: Kukweshana kwenguva refu pakati pehunde yevharuvhu uye kurongedza kunokonzera kusakara kwepamusoro, zvichikonzera kuwedzera kukweshana pakati pehunde yevharuvhu nekurongedza.
(2) Zvimedu zviri pakati nepakati: Zvimedu zviri pakati zvinonamira pakati pevharuvhu disc nechigaro chevharuvhu, zvichiita kuti vharafu ijamu.
(3) Kuyera kwemukati mavharuvhu: Kusachena mukati medhipoziti yepakati mukati mevhavha, kuumba kuyera, kupfupisa nzira dzemukati dzevhavha uye kuita kuti vheji ijamu.
3. Inflexible mafambiro
Kusachinja-chinja kwechiito chemagetsi flange globe valve kunonyanya kuratidzwa nekunonoka kushandura kasi uye torque hombe, uye zvikonzero zvinotevera:
(1) Kusashanda zvakanaka kwemota: Iyo mota iri mumagetsi actuator yakakuvadzwa kana kuita kwayo kuderedzwa, zvichikonzera kusakwana kwekubuda kwe torque.
(2) Kutadza kwekutapurirana nzira: Iyo nzira yekufambisa yakapfekwa, yakasununguka kana kukuvara, iyo inokanganisa kuvhura nekuvhara kumhanya uye torque yevhavha.
(3) Chiratidzo chisina kujairika chekudzora: Iyo yekudzora sisitimu malfunctions, zvichikonzera kusagadzikana kudzora zviratidzo uye inflexible valve kushanda.
3,Fault diagnosis nzira yemagetsi flange globe mavharuvhu
1. Nzira yekucherechedza
Nekutarisa mamiriro ekushanda, mamiriro ekudonha, uye dhigirii yekurongedza kupfeka kwevhavha, tarisa kana paine kusashanda muvharuvhu.
2. Nzira yekuongorora inonzwika
Kushandisa manzwi ezwi kuunganidza masaini panguva yekushanda kwevharuvhu, kuongorora hunhu hwezwi kuti uone kana vharafu yakanganisa.
3. Nzira yekuona tembiricha
Monitor tembiricha shanduko panguva yekushanda kwevharuvhu kuburikidza nematembiricha sensors, ongorora nzvimbo dzisina kujairika tembiricha, uye ongorora chikonzero chekukanganisa.
4. Vibration yekuona nzira
Kushandisa vibration sensors kuunganidza zviratidzo zvekuzunguza panguva yekushanda kwevharuvhu, kuongorora vibration maitiro kuti uone kana vharafu yakanganisa.
5. Hydraulic diagnostic nzira
Ongorora maitiro ehurongwa uye ongorora chikonzero chekukanganisa nekuona maparameter akadai sekumanikidza uye kuyerera mukati mevhavha.
4,Kudzivirira kuchengetedza nzira yemagetsi flange globe mavharuvhu
1. Kuongororwa nguva dzose
Gara uchiongorora kutaridzika kwegetsi flange globe vharafu, tarisa kupera uye kukuvadzwa kwenzvimbo yekuisa chisimbiso, kurongedza, tsinde yevharuvhu uye zvimwe zvikamu, uye nekukurumidza kubata chero matambudziko anowanikwa.
2. Kuzora nguva dzose
Gara uchizora zvinhu zvakadai semagetsi actuators uye nzira dzekutumira kuti uve nechokwadi chekushanda kwevharuvhu.
3. Kuchenesa nguva dzose
Geza tsvina netsvina mukati nekunze kwevharuvhu kudzivirira jamming yevharuvhu, kuvuza, uye kumwe kusashanda.
4. Natsiridza mashandiro
Rongedza zvine mutsindo kuvhura kwevhavha uye kuvhara kumhanya, torque uye mamwe ma paramita kudzivirira yakawandisa kukanganisa uye kupfeka.
5. Anti ngura matanho
Sarudza zvakakodzera anti-corrosion zvinhu zvichibva pane hunhu hwepakati kuti uvandudze kushomeka kwevhavha.
6. Kudzidzira uye kuongorora
Simbisa kudzidziswa uye kuongorora kwevashandisi, kuvandudza hunyanzvi hwekushanda, uye kuderedza zvikanganiso zvevanhu.
5,Mhedziso
Iyo yekutadza kuongororwa uye yekudzivirira kuchengetedza maitiro emagetsi flange eglobe mavharuvhu ndiwo kiyi yekuve nechokwadi chekuchengetedza uye kugadzikana kushanda kwemvura yekudzora masisitimu. Nekuongorora mhando uye zvikonzero zvekukanganisa, zvakasanganiswa nemhosho yekuongorora nzira uye nzira dzekudzivirira dzekuchengetedza, zvinobatsira kuvandudza mashandiro uye hupenyu hwebasa remagetsi flange eglobe mavharuvhu. Mumashandisirwo anoshanda, nzira dzakasiyana-siyana dzinofanira kushandiswa zvakachinjika maererano nemamiriro ezvinhu chaiwo kuti ive nechokwadi chekushanda kwakajairika kwevhavha.
