Njengomishini eyisisekelo yohlelo lwe-condenser vacuum yesitshalo samandla, indandatho yamanzi esiteji 2s-185aiphampu ye-vacuumInomthelela oqondile ekusebenzeni kahle kweyunithi kanye nokusetshenziswa kwamandla ngenxa yokuqina kwayo okusebenzayo. Kodwa-ke, ukugqokwa kwePump Shaft kungenye yehluleka okuvame kakhulu kwalolu hlobo lwemishini, okuvame ukuholela esikhathini sokuphumula esingahleliwe, ukuhlinzwa kwezindleko zokulungisa, kanye nempilo yokuthola imishini. Lo mbhalo uhlaziya izici ezihlelekile, indlela yokugqoka, kanye necebo lokuphatha ukuhlinzeka ngesisombululo esihlelekile sonjiniyela besitshalo samandla.

I. Izici zesakhiwo seShaft Pump 2s-185a kanye nezinselelo zemvelo yokusebenza

1.1 Isakhiwo esiyingqayizivele sephampu yendandatho yamanzi amabili

I-2S-185a vacuum pump amukelisa ukwakhiwa kwe-empoller esiteshini ezimbili ukufeza iziqu ze-vacuum ephakeme ngokucindezela iziteji ezimbili (i-vacuum yokugcina ingafinyelela ku-2.7kpa). Shaft yayo yepompo idinga ukushayela abalingisi abaneziteji ezimbili ngasikhathi sinye futhi baphathe imithwalo eyinhlanganisela:

• Ukufakwa kwemisebe: Ukufakwa kwe-eccentric of the impeller (eccentricity kumayelana ne-4-6mm) kubangela ukuthi amakhangi amaningi aphindiselwa kuma-blades, kanti amandla alinganiswe alinganiswe alinganiselwe angafinyelela ku-200-300n;
• I-Axial Thrust: I-gradient ye-gesi ekhiqizwe yi-compression yesigaba ezimbili yakha ama-axial axist, futhi uhla lwe-axial Force olungapheli lungama-500-800n;
• Umthwalo we-Vibration: Lapho umsizi ekhuphuka noma ibhalansi enamandla yehluleka, ukungalingani kwehluleka i-ISO1940 G2.5 ejwayelekile (≤0.5 ·), nejubane lokudlidliza lingadlula umkhawulo we-4.5mmm / speed.

1.2 Izindawo ezibalulekile zokuxineka kwe-Pump Shaft 2s-185a

Ukulinganiswa kwemininingwane ye-Power Plant Dismantling Case Show (Umdwebo 1) ukuthi ukugqokwa kwephampu kugxile kulezi zindawo ezilandelayo: Ukuthwala indawo yokuhlangana, i-Impeller Keyway

II. Ukuhlaziywa kwendlela ejulile yePump Shaft Wear

2.1 Umphumela wokuhlangana wokukhathala kwensimbi kanye nokugqokwa okuhamba kancane

Gardit Gqoka: Ngaphansi kwesenzo sokushintshana ngokushintshana, ukucindezelwa okuphezulu kakhulu kwe-shear emphemeni we-2s-185a shaft kungafinyelela amandla okuvuna kwezinto ezibonakalayo; Umjikelezo wokuqalisa: Lapho i-Stress Ampliquide Δσ >>PHA, impilo yokuqalisa ingaphansi kwemijikelezo ye-10⁶ (ehambelana nesikhathi esisebenzayo sezinyanga ezi-3).

Ukugqokwa kokunyakaza kwe-micro Ukuhlaziywa kwemboni yemfucumfucu yokugqoka kukhombisa ukuthi ama-akhawunti we-Feoo₄ angaphezu kuka-60%; Kokunye, lapho ingcindezi yokuxhumana yendawo yokuhlangana yehla kusuka kunani lokuklama le-80MPA liye ku-45mpa, izinga lokugqoka likhuphuke ngamahlandla ama-3.

2.2 Ukusabela kwe-Chain kwe-Lubrication Ukwehluleka

Izibalo zamaphampu amaningi amaphutha akhombisa ukuthi ama-60% wokugqoka ahlobene ngokuqondile nokuwohloka kokuthambisa:

a) Ukuqhamuka kwamafilimu amafilimu: Lapho izinga lokushisa elithwala lingu> 90 ℃, ukuvumelana kwamafutha e-lithium-based grease kusuka ku-NLGI Level 2 kuya ku-10μM kuya ku-10μM kuye ku-10μM kuya ku-10μM kuya ku-10μM kuya ku-10μM kuya ku-10μM kuya ku-10μM kuya ku-10μM kuye ku-10μM;

b) Ukungenelela kwePoltant: Ukungena kwamanzi kwe-vapor kubangela ukubaluleka kwe-grease acid ukwanda (> 1.5mgkoh / g), ukusheshisa i-oxidation kanye ne-gelation;

C) Ukuvunyelwa kokuvumelanisa okungafanele: Ngemuva kokudlula umjikelezo onconyiwe womkhiqizi (imvamisa 2000-3000h), ivolumu yokugqoka ikhuphuka ngokungenangqondo.

III. Izici ezinomthelela okhiye kanye nokuhlolwa kwenani

3.1 Amplification of Material and Process Defects

a) Ukuqhathaniswa kwamacala:

I-Shaft yePomc Trump (40cr icima futhi i-areanting yokwelashwa, ubulukhuni be-surceness ra0.4μm): Impilo ephakathi i-48000h;

I-B Porm Pump Shaft (45 Steel esezingeni elijwayelekile ukwelashwa, i-ra1.6μm): Impilo ingama-22000h kuphela, izinga lokugqoka likhuphuke ngezikhathi eziyi-1.8.

b) Ukuhlaziywa kweMetallographic:

Okwama-shaft angahlangabezani nezidingo zobulukhuni bakwa-HRC28-32, okuqukethwe kwe-wartensite komhlaba kungu- <70%, futhi ukumelana nokugqokwa kuncipha ngo-40%; Lapho ubukhulu be-nitride ungqimba bunganele (<0.2mm), impilo yokuxhumana yokuxhumana ifinyeziwe ku-1/3 yenani elijwayelekile.

3.2 Izingozi ezifihliwe zamaphutha wokufaka

a) umthelela wokuphambuka kwesikhungo esigxile: lapho i-coupling offset ingu-> 0.05mm, umzuzu owengeziwe wokugoba unyusa i-deflection shaft ngo-15%; Amandla we-axial akhiqizwe ukuphambuka kwe-angle ye-1 ° angafinyelela ama-20% womthwalo wokuklama.

b) Ukulawula Ukulawulwa Kwemvume: Ukuvunyelwa kwe-Axial of Roped Roller Rouller kufanele kulawulwe ngo-0.08-0.15mm. Kuqinile kakhulu (<0.05mm) kuzokwenza ukuthi kuphakame kakhulu izinga lokushisa, futhi kukhululeke kakhulu (> 0.2mm) kuzodala umthwalo wethonya.

Ukugqokwa kwe-2s-185a pump shaft empeleni kungumphumela wemiphumela ehlanganisiwe yemvelo yemishini, izakhiwo ezibonakalayo kanye nokuphathwa kokulungiswa. Ngokuhlaziya ngobuningiselo yokugqoka kanye nokwakha uhlelo lokulondolozwa kokuvimbela, impilo shaft yepompo inganwetshwa kakhulu. Kunconywa ukuthi ama-Power Plants asungule inqubo yokulawulwa kokuvaliwe efaka ukubuyekezwa komugqa, ukuqapha isimo, kanye nemisebenzi esezingeni elifanele ukunciphisa isilinganiso esingahleliwe phansi ngaphansi kwe-0,5% futhi uzuze i-leap ekuthembekeni kwemishini.

Lapho ufuna amaphampu wekhwalithi ephezulu, ethembekile ye-vacuum, akungabazeki ukuthi u-Yoyik ukhetha ukucatshangelwa. Inkampani isebenza ngokukhethekile ekunikezeni imishini ehlukahlukene yamandla kubandakanya izesekeli ze-turbine, futhi ithole isimemezelo esibanzi ngemikhiqizo nezinsizakalo ezisezingeni eliphakeme. Ngeminye imininingwane noma imibuzo, sicela uxhumane nensizakalo yamakhasimende ngezansi:
