Seal lwezimpawu ukumpompa: incazelo ezihlukahlukene kanye nokubuyekeza

Kwezinga lemikhiqizo yezimboni ngesikhatsi operation iphayiphi, ezihlukahlukene izinhlobo amaphampu nakanjani kuphakama ukulahlekelwa uketshezi. Prevention zamacala la lwezimpawu eziningi, omunye okuzoxoxwa ngokuningiliziwe kulesi sihloko.

Seal lwezimpawu ukumpompa

amaphampu zanamuhla anemisila inqwaba izakhi. Kulokhu, ngqo umsebenzi edingekayo ukugxila ukusebenza evamile futhi abushelelezi umkhiqizo wonkana. Uphawu nezindlala iphampa Ngenxa inkimbinkimbi wakhiwe futhi kalula isicelo isetshenziswa kakhulu kaningi kunakuqala namanye amadivayisi uphawu.

izidingo yokusebenza

Impeller zonke izinhlobonhlobo uzotshala isisetjenziswa sisebenza sibonga injini. Ngokuvamile kuba kagesi. Ngokusebenzisa elihlangana mechanical ngobulili amandla kusuka kushaft injini kuze impeller ngayo, okubekela ke siyahamba. kushaft ngokwalo ngaphandle imishini izindlu, okwenza igobolondo abavuzayo. Ngenxa ukulahlekelwa ongenakugwenywa uketshezi ukusebenza.

Uma usebenzisa uphawu ukugxusha amabhokisi amaphampu, ukuvuza ketshezi akhishwa kungagwenywa. Isebenzisa ubuchwepheshe olulandelayo:

1. Ramming (indlala) uphawu. Limelela aletha impahla fibrous.

2. Lip. Ukuze uthole uphawu ezinjalo, izinto nezimo ukuthi Zingagandelelwa ukwandisa ukuqina. Isetshenziselwa obandayo e imishini ukudonsa nge ongaphakeme ijubane ukujikeleza.

3. Mechanical. Siqukethe amasongo amabili eduze zishiyane komunye nomunye ku kushaft. Omunye uzungeza ne shaft, kanye nezinye uhlala kungahambi ngokuphelele.

4. Umqhewu. Eyesibili igama - uxhaxha. It kubhekwa yesimanje okunokwethenjelwa uphawu ukubukwa kakhulu. Kwethulwa njengoba indandatho kusuka ingxubevange esithambile. It is lisetshenziswe amaphampu multistage, lapho ukusetshenziswa nobunye ubuchwepheshe kungaba ngokuphawulekayo nomthelela ukusebenza kahle.

Ngaphezu kwalokho, kukhona amadivayisi angadingi zamanzi, ezifana amaphampu nge elihlangana kazibuthe kanye Rotor ezimanzi.

Incazelo Seals, mechanical

izinto Slotted ezisetshenziswa kakhulu ukunikeza uphawu amaphampu ngwenya. Ababona kuncike nezidingo esikhethekile ukuvuza uketshezi. Lapha ineqhaza elikhulu isikhathi wokusebenza.

Uphawu nezindlala amaphampu uvele cishe ngasikhathi sinye nge imishini ngokwayo for uzotshala eziwuketshezi. Le ndandatho eziyingqayizivele impahla lunemicu okuyinto zisekelwe ukugxusha, yingakho amagama abo. I nokupakisha kufanele wetted uthuthwa uketshezi iphayiphi. Kubalulekile Ukupholisa ngomoya kanye Lubrication of indlala. Zona efanayo ogelezayo nokumanzisa ketshezi igcwele ukulahlekelwa. futha ihora kuhilela ukulahlekelwa 1-15 amalitha amanzi. Uma gasket is hhayi wetted, indaba ilahlekelwa iwusizo ngokushesha "zishe."

Kuyadingeka njalo ukugcina gaskets. Compressors namaphampu ngesikhathi esifanayo awukwazi ukuya kulelo, futhi ingenye Izinzuzo ebaluleke lwezimpawu. Kuyiwona gqwa "silingo-up" cuff.

ukuhlukahluka ejwayelekile zamanzi ngoba imishini futha

Izinto zesimanje emakethe linikeza ezihlukahlukene seal for amaphampu; seal ezivamile amelwa izinhlobo ezimbili eziyinhloko:

1. Akukona ukuhlakanipha ukufihla nge onqenqemeni nakakhulu. Inhloso esemqoka - ukuvimbela ukulahleka ketshezi akhishwa.

2. Sleeves kwagcizelela zibhonge nokukodwa onqenqemeni. Isetshenziselwa lokuvikeleka kwezifiso ezisemqoka ezingumphumela kwakwakhe kusuka izintuli nokungcola. Futhi, ungavumeli fluid ukushiya izinto zokuthutha.

Uma sicabangela indlela zokukhiqiza, singakwazi ukuhlukanisa lwezimpawu:

• nge onqenqemeni olubunjiwe;

• nge onqenqemeni, le machining zokugcina.

Kuye uhlobo iraba kukhona cuffs ezifana:

1. Ngokusekelwe iraba nitrile. Imikhiqizo ezenziwe kusukela 1, 2 neye-3 womnyaka iraba banga. Libhekene kuqhathaniswa okusezingeni eliphezulu negative embundwini yokusebenza lokushisa (-30, -45, futhi -60 ° C ngokulandelana).

2. Ngesisekelo iraba fluoro. Raw impahla - amaqembu iraba 1 futhi 2. Uma uzotshala uwoyela ukudluliswa noma amaminerali ukumelana okushisa afinyelela ku-170 ° C.

3. Of abicah zenjoloba. Ngo womshini amathayi isetshenziswa kuphela iqembu elilodwa. umkhawulo engezansi nokupakisha lokushisa zokusebenza -55 ° C.

Njengomthetho, cuffs yesimanje ihambisane iziphethu. Ziyakwazi efanelekayo seals lapho imiphini ka diameters ezahlukene.

Entwasahlobo kungenzeka enikeziwe ngokuhlukile le ndlala uma kulindeleke ukuba asebenze nakhu sekuvela umsebe wokukhanya 20 mm noma ezingaphezu kwezingu-120 mm.

Nemthombo ibhokisi: ukusebenza izici ngoba epompa ukusebenzisa kangcono

Njengoba umthetho, cuffs abahluke ngaso kwezinye izimvu zamanzi ngoba ivumelana nezimo, plasticity. High bafake ukumelana nakho a inzuzo enkulu yemikhiqizo. umphumela azinakwa ku kushaft wenabisa ingxenye isicelo.

Ukusebenza izici encike ngqo kwi isakhiwo kanye nendlela okwakheke ngayo sealant, eye yasetshenziswa ekukhiqizeni. Kuye aluka kukhona idayagonali (le ngokusebenzisa futhi kuhlanganisiwe) nokukodwa multilayer gaskets (ebhekisela isakhiwo core). Ngokusho ukubunjwa cuff yilezi:

• asbestos futhi okungezona asbestos;

• omisiwe futhi elifakwe (njengoba lisetshenziswe impregnation amafutha, graphite futhi ingxube ingcina);

• kwagcizelela futhi unreinforced.

Seals esetshenziselwa uphawu compounds centrifugal, piston amaphampu futhi ukucindezela wokubacindezela. Padding singasetshenziswa imishini for uzotshala plunger uketshezi. Uma ufaka umkhiqizo akufanele ilibaleke ukuthi amaphampu indlala uphawu uyolahlekelwa ethile ketshezi, okukhulunywe ngaso ngenhla.

seal Graphite-Ceramic

Lena ngenye yama-izinhlobo cuffs for uzotshala imishini. Ukusetshenziswa lolu hlobo uphawu ngakususi ngokuphelele ingress ukusebenza uketshezi ukuhlomisa motor. Kuphi lwezimpawu isicelo ohlangene graphite-Ceramic? amaphampu amanzi, kanti lokhu kuhambisana uphawu mechanical, hhayi okungaka. Ngokuvamile, isicelo evinjelwa kuphela izindlela ebusweni ingxenye.

ukuphila Izikhungo ongafinyelela iminyaka engu-10. Kufanele banamathele ukusetshenziswa ngemfanelo esiteshini ukudonsa. Izidingo main wenza ngesikhathi imishini:

1. Ukuswelakala kokusebenza ngokuhlanganyela "run owomile." It is nhlobo ukugcina futha kule "ku" Imodi, uma kukhona uketshezi ohlelweni.

2. Kungcono ukuletha izidakamizwa elicwengiweyo kunazo. Ukuba khona ukungcola ngeke unciphise inkonzo cuff.

3. Qiniseka ukuthi unamathele umbuso lokushisa.

Izinzuzo seal for amaphampu amanzi uphawu

Cuffs imishini ukumpompa amanzi libukeka Nokwelukiweyo lace sikwele. Asbhestosi (ukotini noma Bast) ntambo kungenzeka ukufakwa zethusi noma zethusi wire. Seals amanzi uphawu has a core eyenziwe phambili. usayizi Tape 5 * 0.5. Kungase kusetshenziswe esikhundleni inetha 4 phambili izintambo.

gaskets osetshenziswayo ngamanzi uphawu, njengoba umthetho, ohlangothini ukuncela. Kodwa kungenzeka ukuzisebenzisa, futhi ngaphesheya. usayizi nokupakisha kuhlobene ububanzi kushaft. Inombolo enkulu izindandatho uphawu - 5.

Indlela ukukhetha nomlilahlo

Ukukhethwa ezimpawu olwenziwa eziningi izici. Ngokungangabazeki, le ebaluleke kakhulu umbuzo nokwethenjelwa. Phakathi kokunye, indlela ebalulekile kubhekwe izindleko. imingcele engeziwe ukuze ayicabangele lapho ekhetha kudivayisi:

• namahora okusebenza;

• ukulahlekelwa uketshezi;

• eshalofini-ukuphila;

• izindleko ukuthi kwakuyovela uma ukulungisa.

Ngaphezu kwalokho, ukukhethwa seal for amaphampu liyakushunyayelwa osayizi based. Lezi zihlanganisa diameters bangaphakathi nabangaphandle, ukuphakama kanye ukushuba substrate.

What do abathengi

Abaningi baye bathola inhlangano indlala ngoba futha owodwa esigabeni. Ngokuvamile imakwe yizinhlobonhlobo nokupakisha. Ukusetshenziswa lwezimpawu akugcini ngesivinini imiphini.

Kuyaphawuleka ukuthi lezi zimvu zamanzi azizange uphawu amaphampu nivame ziphephile abicah ezisekelwe ukuzinza enkulu ezishisayo.

Ukuhluka ngokuqukethwe okusezingeni eliphezulu carbon iyehlisa isilinganiso ukunwetshwa ngokwandisa lokushisa uketshezi. A aramid fibre afuthwe ngesibulali PTFE ku nokupakisha vumela ukusebenza endaweni egqwalisayo zamakhemikhali umkhakha, izitshalo amandla futhi umkhakha ephepheni.
