Kuongororwa kwezvikonzero zve vibration ye vertical turbine pombi

1. Vibration inokonzerwa nekuiswa uye kutsauka kwegungano kwevertical turbine pombi
Mushure mekuisirwa, mutsauko uripo pakati pehupamhi hwepombi yepombi uye yekurovera pad uye verticality yepombi yekusimudza inokonzeresa kuzunguzika kwemuviri wepombi, uye aya matatu ekutonga maitiro ane hukama kune imwe nhanho. Mushure mekunge muviri wepombi waiswa, kureba kwepombi yekusimudza uye musoro wepombi (pasina sefa skrini) ndeye 26m, uye zvese zvakamiswa. Kana kutsauka kwakamira kwepombi yekusimudza kwakakurisa, pombi inokonzeresa kudedera kwepombi inosimudza uye shaft apo pombi inotenderera. Kana iyo pombi yekusimudza yakamira zvakanyanya, kushushikana kwekuchinja kunogadzirwa panguva yekushanda kwepombi, zvichikonzera kuputsika kwepombi yekusimudza. Mushure mekunge pombi yakadzika yegomba yaunganidzwa, kukanganisa kwekumira kwepombi yekusimudza kunofanirwa kudzorwa mukati me2mm mukati mehurefu hwakazara. Chikanganiso chakamira uye chakachinjika ndeche 0 pombi.05/l000mm. Iyo static balance kushivirira kwepombi musoro impeller haina kupfuura 100g, uye panofanirwa kuve ne8-12mm kumusoro uye kuzasi serial clearance mushure mekusangana. Iko yekumisikidza uye gungano clearance kukanganisa ndicho chikonzero chakakosha chekuzunguza kwemuviri wepombi.

2. Chamupupuri chedhiraivha shaft yepombi
Whirl, inozivikanwawo se "spin", ndiko kudzvinyirirwa kwega kweshaft inotenderera, iyo isina hunhu hwekuzunguza kwemahara kana isiri rudzi rwekudzvinyirirwa. Iyo inoratidzirwa nekutenderera kwekufamba kweshaft pakati pemabheya, izvo hazviitike kana shaft inosvika pakukurumidza kwakaoma, asi inoitika muhukuru hukuru, iyo isinganyanyi kushamwaridzana nekukurumidza kwegomba pachayo. Kuzungunuka kwepombi yetsime rakadzika kunonyanya kukonzerwa nekusakwana kutakura lubrication. Kana mukaha uri pakati pegomba nekutakura wakakura, kutungamira kwekutenderera kunopesana neiyo shaft, iyo inonziwo kuzununguka kwegomba. Kunyanya, iyo dhiraivha yepombi yakadzika yepombi yakareba, uye kubvumidzwa kwakakodzera pakati peiyo rubber bearing uye shaft ndeye 0.20-0.30mm. Kana paine kumwe kucheneswa pakati peshaft nebearing, shaft yakasiyana nebearing, kureba kwepakati kwakakura, uye clearance inoshaya lubrication, senge yakadzika tsime pombi rubber bearing lubrication Iyo pombi yemvura inoputsika. Yakavharwa. Kusashanda zvakanaka kunoita kuti pasave nemvura yakakwana kana nguva isati yakwana, uye inowanzozunguzika. Iyo magazini inobatana zvishoma neiyo rubber bearing. Iyo magazini inoiswa kune tangential simba rekubereka. Kutungamira kwesimba kunopesana nekwakananga kweshaft speed. Muchikamu chekucheka kwenzvimbo yekubatana yemadziro anotakura, pane katsika kekudzika pasi, saka jenari inongotenderera ichitevedza madziro anotakura, ayo akaenzana nepeya yegiya remukati, achigadzira kutenderera kwakatarisana negwara. shaft kutenderera.

Izvi zvakasimbiswa nemamiriro ezvinhu mukushanda kwedu kwezuva nezuva, izvo zvichaitawo kuti rubber bearing inopisa kunze kwechinguva chiduku.

3. Kudengenyeka kunokonzerwa nekuremerwa kwepombi ye vertical turbine
Iyo yekusunda pad yepombi muviri inotora tin-based babbitt alloy, uye inotenderwa mutoro i18MPa (180kgf/cm2). Kana pombi yepombi yatangwa, iko kutsvedza kwepadhi yekusundira kuri mumuganhu wekuzora. Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha yegedhi inoiswa panobuda mvura pombi. Kana pombi yatanga, vhura vharuvhu yegetsi. Nekuda kwekuiswa kwe silt, ndiro yevhavha haigone kuvhurwa kana vheji yegedhi remanyorero yakavharwa nekuda kwezvikonzero zvevanhu, uye kupera hakusi panguva, izvo zvichaita kuti muviri wepombi uzununguke zvine chisimba uye iyo yekukanda pad ichapisa nekukurumidza.

4. Kuzungunuswa kwemhepo panobuda pombi yeturbine yakatwasuka. 
Mapombi epombi akaiswa munhevedzano. Dg500 pombi pfupi. Tarisa vharafu. Electric butterfly valve. Manual valve. Main pombi uye mvura sando eliminator. Kubvongodzwa kwekufamba kwemvura kunoburitsa zvisingaite pulsation phenomenon. Mukuwedzera kune kuvhara kwevhavha yega yega, kupikisa kwemunharaunda yakakura, zvichiita kuti kuwedzerwa kwekukurumidza uye kudzvinyirira. Shanduko, ichiita pakudengenyeka kwemadziro epombi uye muviri wepombi, inogona kuona iyo pulsation phenomenon yeiyo pressure geji kukosha. Iyo pulsating pressure uye velocity minda mumhirizhonga inoyerera inoramba ichiendeswa kumuviri wepombi. Kana iyo yakakura frequency yekuyerera kwemhirizhonga yakafanana neyechisikigo frequency yeyakadzika tsime pombi system, iyo system inofanirwa kutora simba uye kukonzera vibration. Kuti uderedze mhedzisiro yekuzununguka uku, vharuvhu inofanira kunge yakavhurika zvizere uye spool inofanira kuva yehurefu hwakakodzera uye rutsigiro. Mushure mekurapa uku, kukosha kwekudengenyeka kwakaderedzwa zvakanyanya.

5. Torsional vibration yepombi yakatwasuka
Kubatana pakati peiyo refu shaft yakadzika tsime pombi uye mota inotora elastic coupling, uye hurefu hwakazara hwe drive shaft ndeye 24.94m. Panguva yekushanda kwepombi, kune superposition yekuzununguka kukuru kweakasiyana angular frequencies. Mhedzisiro yekubatanidza kwemaresonance maviri akareruka pane akasiyana angular frequency haingori nyore harmonic vibration, kureva, torsional vibration ine madhigirii maviri erusununguko mumuviri wepombi, izvo zvisingadzivisike. Kudengenyeka uku kunonyanya kukanganisa nekukuvadza ma thrust pads. Naizvozvo, kana iri nyaya yekuona kuti imwe neimwe ndege inorovera pad ine mafuta anoenderana, shandura iyo 68# oiri yakatsanangurwa mune yepakutanga mirairo isina kurongeka kuita 100# mafuta kuwedzera viscosity ye thrust pad yekuzora mafuta uye kudzivirira iyo hydraulic lubricating firimu. ye thrust pad. kuumba nekuchengetedza.

6. Kudengenyeka kunokonzerwa nekubatana kwemapombi akaiswa padanda rimwe chete
Iyo yakadzika tsime pombi uye mota yakaiswa pazvikamu zviviri zve 1450 mmx410mm pamatanda ekongiri yakasimbiswa, iyo yakadzika misa yepombi yega yega uye mota ndeye 18t, iko kumhanya kwemapombi maviri ari padhuze pane imwechete furemu danda imwe mbiri yemahara Vibration system. Kana kuzununguka kweimwe injini kunodarika mwero zvakakomba uye bvunzo inomhanya isina mutoro, ndiko kuti, iyo elastic coupling haina kubatana, uye amplitude kukosha kwemota yeimwe pombi mukushanda kwakajairika inokwira kusvika 0.15mm. Mamiriro ezvinhu aya haasi nyore kuona, uye kutarisirwa kunofanira kubhadharwa kwairi.
