Muinjiniya yepombi, kusarudzwa kwakaringana kwemavharuvhu emagetsi ndeimwe yemamiriro ekuvimbisa kusangana nezvinodiwa zvekushandisa. Kana iyo valve yemagetsi inoshandiswa isina kusarudzwa zvakanaka, haizongokanganisa kushandiswa chete, asiwo inounza migumisiro yakaipa kana kurasikirwa kwakakomba, saka, kusarudzwa kwakarurama kwemavhavha emagetsi mukugadzirwa kwepombi engineering.
Nzvimbo yekushanda yevhavha yemagetsi
Mukuwedzera pakuteerera kumiganhu yepombi, kunyanya kukoshesa kunofanira kubhadharwa kumamiriro ezvakatipoteredza ekushanda kwayo, nokuti chigadziro chemagetsi muvhavha yemagetsi chigadziro che electromechanical, uye kushanda kwayo kunokanganiswa zvikuru nemamiriro ayo ekushanda. Kazhinji, nzvimbo yekushanda yevhavha yemagetsi yakaita seinotevera:
1. Kuiswa kwemukati kana kushandiswa kwekunze nematanho ekudzivirira;
2. Kuiswa kwekunze mumhepo yakashama, nemhepo, jecha, mvura nedova, chiedza chezuva uye kumwe kukukurwa;
3. Iine gasi rinopisa kana rinoputika kana nzvimbo yeguruva;
4. Humid tropical, dry tropical environment;
5. Kupisa kwepakati pepipeline kwakakwirira kusvika 480 ° C kana pamusoro;
6. The ambient tembiricha iri pasi -20°C;
7. Zviri nyore kuzarirwa kana kunyudzwa mumvura;
8. Mamiriro ezvinhu ane radioactive zvinhu (nuclear power plant uye radioactive material test equipment);
9. Mamiriro ezvinhu echikepe kana doko (nemunyu wakapfapfaidza, mold, uye mwando);
10. Zviitiko nekudengenyeka kwakanyanya;
11. Nguva dzinopisa moto;
Kune mavharuvhu emagetsi munzvimbo dzataurwa pamusoro apa, chimiro, zvinhu uye matanho ekudzivirira emagetsi emagetsi akasiyana. Nokudaro, chigadziro chemagetsi chevhavha chinoenderana chinofanira kusarudzwa maererano nemamiriro ekushanda ataurwa pamusoro apa.
Kushanda zvinodiwa zvemagetsimavharuvhu
Zvinoenderana nezvinodiwa zveinjiniya, yevhavha yemagetsi, basa rekutonga rinopedzwa nemagetsi emagetsi. Chinangwa chekushandisa mavharuvhu emagetsi ndechekuona isiri-manual kudzora magetsi kana komputa kutonga kwekuvhura, kuvhara uye kugadzirisa kubatanidza mavharuvhu. Midziyo yemagetsi yanhasi haingoshandiswe kuchengetedza manpower. Pamusana pekusiyana kukuru kwekushanda uye hutano hwezvigadzirwa kubva kune vakasiyana-siyana vanogadzira, kusarudzwa kwemagetsi emagetsi uye kusarudzwa kwemavhavha zvakakosha zvakaenzana kune purojekiti.
Kudzora kwemagetsi kwemagetsimavharuvhu
Nekuda kwekuenderera mberi kwekuvandudzwa kwezvinodiwa zveindasitiri otomatiki, kune rumwe rutivi, kushandiswa kwemagetsi mavharuvhu kuri kuwedzera, uye kune rumwe rutivi, zvinodiwa zvekutonga zvemagetsi mavharuvhu zviri kuwedzera uye zvakanyanya kuoma. Nokudaro, magadzirirwo emagetsi emagetsi maererano nekugadzirisa magetsi anogara achivandudzwa. Nekufambira mberi kwesainzi uye tekinoroji uye kufarirwa uye kushandiswa kwemakomputa, nzira itsva uye dzakasiyana-siyana dzekudzora magetsi dzicharamba dzichionekwa. Nokuda kwekutonga kwese kwemagetsivharafu, kutarisa kunofanira kubhadharwa pakusarudzwa kwemaitiro ekudzora evhavha yemagetsi. Semuyenzaniso, zvinoenderana nezvinodiwa zvepurojekiti, kungave kushandisa iyo centralized control modhi, kana imwe chete yekudzora modhi, ingave yekubatanidza nemimwe michina, chirongwa chekutonga kana kushandisa komputa chirongwa chekudzora, nezvimwewo, mutemo wekutonga wakasiyana wakasiyana. . Sample yemugadziri wemagetsi emagetsi evhavha inongopa iyo yakajairwa magetsi ekudzora musimboti, saka dhipatimendi rekushandisa rinofanira kuita kuburitswa kwehunyanzvi nemugadziri wemagetsi emagetsi uye kujekesa zvinodiwa zvehunyanzvi. Mukuwedzera, pakusarudza vheji yemagetsi, unofanirwa kufunga nezvekutenga imwe yevhavhavha yemagetsi. Nokuti kazhinji, mutongi anoda kutengwa zvakasiyana. Muzviitiko zvakawanda, kana uchishandisa kutonga kumwe chete, zvinodikanwa kutenga mutongi, nekuti zviri nyore uye zvakachipa kutenga mutongi pane kugadzira uye kugadzira iyo nemushandisi. Kana iyo yemagetsi kutonga kuita isingakwanise kuzadzisa injiniya dhizaini zvinodiwa, mugadziri anofanirwa kurongedzerwa kugadzirisa kana kugadzirazve.
Iyo valve yemagetsi mudziyo mudziyo unoona hurongwa hwevhavha, otomatiki control uye kuremote control *, uye mafambiro ayo anogona kudzorwa nehuwandu hwekurohwa, torque kana axial thrust. Sezvo maitiro ekushanda uye kushandiswa kwehuwandu hwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,mushonga wekushanda kwechigadziro, uye nzvimbo yevhavha papombi kana midziyo,kusarudzwa kwakaringana kwevhavharuvhuvhu kunokosha kudzivirira kuwandisa. iyo torque inoshanda yakakwira kupfuura torque yekudzora). Kazhinji, hwaro hwekusarudzwa kwakaringana kwemagetsi mavharuvhu emagetsi ndeaya anotevera:
Operating torqueIyo inoshanda torque ndiyo huru parameter yekusarudza valve yemagetsi mudziyo, uye inobuda torque yechigadzirwa chemagetsi inofanira kuva 1.2 ~ 1.5 nguva dzevhavha yekushanda torque.
Pane maviri makuru emuchina zvimiro zvekushandisa iyo thrust vharafu yemagetsi mudziyo: imwe haina kurongedzerwa ne thrust disc uye yakananga inobuda torque; Imwe yacho ndeyekugadzirisa ndiro yekurovera, uye torque inobuda inoshandurwa kuita inoburitsa kuburikidza ne stem nut mundiro yekukandira.
Huwandu hwematenderedzwa ekutenderera kweshaft inobuda yevhavhavhavhavha yemagetsi inoenderana nedhayamita yezita revharuvhu, kukwirira kwehunde uye nhamba yeshinda, iyo inofanirwa kuverengerwa zvichienderana neM=H/ZS (M ndiyo nhamba yese yekutenderera iyo mudziyo wemagetsi unofanirwa kusangana nawo, H ndiko kureba kwekuvhura kwevharuvhu, S ndiyo shinda yeshinda yevhavha stem transmission, uye Z ndiyo nhamba yemisoro yakarukwavharafudzinde).
Kana iyo dhayamita yetsinde yakakura inobvumirwa nemagetsi emagetsi haigoni kudarika nepakati pevhavha yakashongedzerwa, haigoni kuunganidzwa muvhavha yemagetsi. Naizvozvo, dhayamita yemukati yegomba rekubuda shaft yeactuator inofanira kunge yakakura kupfuura dhayamita rekunze rehunde yevhavha yakavhurika tsvimbo. Kune yevhavha yetsvimbo yakasviba muchikamu che rotary valve uye multi-turn valve, kunyangwe dambudziko rinopfuura revhavha stem dhayamita risingatariswe, dhayamita yevhavha tsinde uye saizi yekiyi nzira inofanirawo kutariswa zvizere pakusarudza, kuitira kuti ishande zvakajairika mushure megungano.
Kana iyo yekuvhura uye yekuvhara yekumhanyisa yevhavha yekubuda yakakurumidza, zviri nyore kugadzira sando yemvura. Nokudaro, kuzarura kwakakodzera uye kuvhara nokukurumidza kunofanira kusarudzwa maererano nemamiriro akasiyana ekushandisa.
Vagadziri vevhavha vane zvavanoda zvakakosha, kureva kuti vanofanirwa kutsanangura torque kana axial mauto. Kazhinjivharafuma actuators anoshandisa torque-yekumisikidza couplings. Kana ukuru hwechigadzirwa chemagetsi chatemwa, torque yayo yekutonga inotemerwa zvakare. Kazhinji kumhanya panguva yakatarwa, mota haizoremerwe. Zvisinei, kana mamiriro ezvinhu anotevera akaitika, zvinogona kukonzera kuwandisa: kutanga, simba rekupa simba rakaderera, uye torque inodiwa haigone kuwanikwa, kuitira kuti motokari irege kutenderera; yechipiri ndeyekukanganisa kugadzirisa torque yekumisa nzira kuti iite yakakura kupfuura yekumisa torque, zvichikonzera kuenderera kwakanyanyisa torque uye kumisa mota; chechitatu kushandiswa kwepakati, uye kuunganidza kwekupisa kunogadzirwa kunodarika iyo inobvumirwa tembiricha yekukwira kukosha kwemota; Chechina, dunhu reiyo torque yekudzikamisa meshini rinokundikana pane chimwe chikonzero, izvo zvinoita kuti torque iwedzere; Chechishanu, ambient tembiricha yakawandisa, izvo zvinoderedza kupisa kwemota.
Kare, nzira yekudzivirira mota yaive yekushandisa fuses, overcurrent relays, thermal relays, thermostats, nezvimwewo, asi nzira idzi dzine zvadzo zvakanakira uye nekuipa. Iko hakuna nzira yekudzivirira yakavimbika yemidziyo inotakura zvinhu zvakaita semagetsi emagetsi. Nokudaro, kusanganiswa kwakasiyana-siyana kunofanira kugamuchirwa, iyo inogona kupfupikiswa mumhando mbiri: imwe ndeyekutonga kuwedzera kana kuderera kwekupinza ikozvino kwemotokari; Chechipiri ndechekutonga mamiriro ekupisa emotokari pachayo. Chero nzira, chero nzira inofunga iyo yakapihwa nguva muganho wekupisa kwemota.
Kazhinji, nzira yekutanga yekudzivirira yekuremedza ndeye: kuchengetedzwa kwekuremerwa kwekuenderera mberi kwekushanda kana jog kushanda kwemota, uchishandisa thermostat; Nekudzivirira kwemota stall rotor, thermal relay inogamuchirwa; Kune tsaona dzenguva pfupi, ma fuse kana overcurrent relays anoshandiswa.
