Indlala uphawu futha. design Ukupakisha

Ngo kokuhlinzwa, ukulahlekelwa futha uketshezi zenzeka. Ngokuvamile, lokhu kwenzeka endaweni yokuxhumana kwawo ukuze iphayiphi. , Kumelwe usebenzise futha nokupakisha ukuyigwema. Yilokho kule divayisi okuzoxoxwa ngayo.

Indlala uphawu futha

On yesimanje inhlabathi centrifugal ezifakiwe izakhi ezihlukahlukene design nemininingwane. Kuyadingeka ukuqinisekisa operation evamile izingxenye ngabanye hhayi kuphela, kodwa futhi yonke imishini. futha nokupakisha isetshenziswa kanengi ukudlula ezinye izindlela. Isizathu salokhu iyona lula design and ukufakwa lula.

Izimfuneko uphawu

Household amaphampu isebenze ngokusebenzisa impeller, okuyinto ethatha ku injini. Njengomthetho, kuba kagesi. Ukujikeleza impeller kungenxa amandla motor nge elihlangana lokukhanda. Umphini motor alikho izindlu. Ngakho-ke, yobunzima yayo siphukile. Ngenxa yalokhu ukuvuza zenzeka esiningi uketshezi. Uma usebenzisa futha nokupakisha, inkinga kungagwenywa. Namuhla, izindlela ezahlukene ezisetshenziswa:

1. uphawu lokugxusha. Kulomjikelezo ukwakhiwa ehlanganisa impahla fibrous.
2. uphawu Lip. Njengoba phawu isetshenziswa izinto okuyinto ukusebenza kahle ukungezwani. Ukuze wandise rigidity isakhiwo usebenzisa ukugcizelela. Lolu hlobo lwe-amaphampu ogibele yasendlini lapho ijubane ukujikeleza kuyinto ephansi.
3. Gap lwezimpawu. It has elinye igama - the uxhaxha. Yilolu hlobo onokwethenjelwa kunayo yonke uphawu. Kuyinto isakhiwo isiyingi wenza elinama esithambile. Lolu hlobo igibele amaphampu multi-esiteji. Uma ukusungula nezinye izimvu zamanzi, lokho kuyoholela ekulahlekelweni ukusebenza iyunithi.
4. Mechanical nokupakisha indlala. Lolu hlobo umelwe ngesimo amasongo amabili eduze elise komunye nomunye. Eyokuqala haya ukunyakaza ukujikeleza kanye kushaft ezisebenza kanye static yesibili.

Kukhona imishini uzotshala, lapho ukusetshenziswa uphawu ayidingekile. Le divayisi, ehlanganisa i-elihlangana kazibuthe.

Ukusebenza lwezimpawu

I nokupakisha shaft futha lusetshenziswa ngophawu. Njengomthetho, basuke esetshenziselwa izinhlobo ngwenya njengoba ungazange izimfuno ezikhethekile kwi ukuvuza. Kulokhu, okubaluleke kakhulu yindlela impilo isevisi eside.

IziMpawu, mechanical bavele emakethe namadivayisi ngokudlulisela uketshezi. Kungani ebizwa? Uphawu has simise isiyingi ehlanganisa impahla fibrous. Leli fomu senziwa ngesisekelo lo ukugxusha. Indaba fibrous kumele njalo wetted esebenzisa ketshezi akhishwa. It uba hhayi kuphela uwoyela kodwa futhi njengendlela material lwaluyophola. Ngakho-ke, ukulahlekelwa uketshezi namanje awukwazi ugweme. Omunye ihora ngaphambi umsebenzi idliwe 15 amalitha amanzi. Uma ungenalo ezimanzisa impahla fibre, uzovutha ngokushesha futhi kufanele ufake entsha.

Kufanele kuqashelwe ukuthi izakhi abadinga ukunakekelwa njalo. Esikhundleni nokupakisha wenziwa ngaphandle yokwehlukanisa futha imoto. Lokhu kuyinzuzo enkulu. Awudingi ukubiza onguchwepheshe. cuffs Ukudonsa kwenziwa ngokuzimela.

design Ukupakisha

Kuze kube manje, emakethe inikeza anhlobonhlobo indlala lwezimpawu.

Izinhlobo ezinkulu yilezi:

1. Okuhlezi emqondweni impahla nomunye onqenqemeni. Usebenzela ukuvimbela ukuvuza.
2. Okuhlezi emqondweni cuff nge eyodwa onqenqemeni. Le divayisi isetshenziselwa izinhlangano zokuvikela izimvu zamanzi kusuka ukungcola kanye kusukela ukulahlekelwa uketshezi phakathi uzotshala.

Ngaphezu kwalokho, onqenqemeni zingaba ezinguqulweni eziningana:

• ejwayelekile;
• nge machining.

Sealers nazo ezihlukaniswe uhlobo indaba for iraba asetshenziswe cuffs. Phakathi kwabo kukhona izinto ezinjalo:

• Rubber. Lezi zincwadi zenziwa amamaki ezahlukene zenjoloba. inzuzo ngokuyinhloko ikhono lokubekezelela okushisa aphansi.
• Fluororubber. esetshenziswa kuphela emabanga iraba 1 no-2. Ingabe uyakwazi ukumelana okushisa afinyelela ku-170 ° C, okuyinto kuba yipumelelo lokha uzotshala amafutha viscous.
• Silicone. Kusebenza kuphela Class 1 zenjoloba. Uyakwazi ukumelana okushisa afinyelela ku -60 ° C.

cuff Modern ukukhiqiza kanye isiphethu, okuyilona elidingekayo ukuze umuntu uphawu imiphini ka diameters ezahlukene.

Izimpawu ezibonakalayo uphawu

Uma kuqhathaniswa namanye zamanzi, cuff sibonisa izakhiwo nezimo futhi ductile. izici Operational incike uhlobo uphawu impahla. Kuye isakhiwo, bangase babe aluka idayagonali, nenhliziyo. Ukwakheka wabo futhi ezahlukene, futhi kungaba:

• ingaqukatha asbestos;
• kube ifomu eyomile noma elifakwe;
• kwagcizelela futhi unreinforced.

Iphinde isetshenziselwe ukugxusha ibhokisi ukubekwa uphawu amaphampu centrifugal futhi ukucindezela wokubacindezela. Uma ufaka kufanele kuphawulwe ukuthi ezinye ketshezi akhishwa isetshenziswa ukumanzisa uphawu.

Izinzuzo uphawu indlala

Ngakho, cuff ukuthi isetshenziswa ukuze uthumele ketshezi has intambo ifomu aluka. Lokuluhlaza eyenziwe ukotini noma asbestos. Ngezinye izikhathi ifakwe wire ithusi. Phakathi senziwa ngomthofu. Lapho kungenzeka ukwelukwa esetshenziswa kusuka 4 izindikimba.

Kufakiwe lwezimpawu ohlangothini ukuncela. Nokho, bakwazi ukukhwezwa kwezinye izindawo. Inombolo ukuphrinta incike ubukhulu kushaft.

Njengoba le ndlala kuyakhethwa

Ngaphambi kokuthenga sealant, kubalulekile ukuba sicabangele eziningi izici. Udaba sokuqala nesibaluleke kakhulu iyona Inkomba nokwethenjelwa. Esinye isici esibalulekile - izindleko. Phakathi kwezinye nenqubo kubhekwe:

• ezisebenza isikhathi;
• Inkomba ethize ukulahlekelwa uketshezi;
• ukuphila;
• izindleko bayawukhanda noma esikhundleni.

Indlala uphawu Kufanele ukhethe, esekelwe osayizi. Lapha, ebuka yangaphandle futhi kwangaphakathi ububanzi futhi udonga ukujiya.

Izibuyekezo

Abasebenzisi abaningi bayajabula ngophawu indlala. Ukusebenzisa ke ukukhweza futha owodwa esigabeni, babona uphawu kufanelekile yimuphi isivinini input. Imodeli ethandwa kakhulu iyona olunegama lika-silicone grease. Bayakwazi ukumelana okushisa aphezulu. Ezinye imicu eminingana ziphathwe uketshezi ekhethekile, okuvumela uphawu ukumpompa uketshezi ezonakalisayo.

Abasebenzisi sinake design kophawu. Cuff siqukethe nokwelukiweyo asbestos ntambo. Ngezinye yokukhiqiza yayo liyasetshenziswa wire ithusi. Le nhlanganisela kwenza kube uqine ngokwanele, futhi ayikho ngaphansi izenzo ketshezi akhishwa.

izindleko

Njengoba kushiwo ngaphambili, kukhethwa uphawu kufanele kubhekwe izici ezithile. Ezisithintayo izindleko zedivayisi. intengo zabo zokhahlamba kusuka ruble 100 kuya ku-500.

isiphetho

Ukuze ugweme ukuvuza enkulu ketshezi, esetshenziselwa ukugxusha ibhokisi packings. Basuke lwenziwa embodiments ahlukahlukene. Yiqiniso, ukuphelelwa uketshezi kuyoba, kodwa incane. Umqulu uzobe kudliwe ogelezayo nokumanzisa okokusebenza uphawu. Abasebenzisi abaningi bayajabula nale divayisi. Njengomthetho, ubekwa phezu amaphampu ngwenya esetshenziswa ukumpompa amanzi angcolile. ukuphila inkonzo yabo mikhulu, futhi enokwethenjelwa. Ngo ngentengo elincane, ungathenga eliphezulu impahla, okuyinto izothatha isikhathi eside.

Ngakho, sabuka yiziphi indlala uphawu amaphampu centrifugal, futhi yiziphi izinhlobo zihlukaniswa.
