Uphawu lwesicatshulwa. Isityikityhi esicwangcisiweyo kabini: GOST

Isitywina somatshini iyunithi esetyenziselwa ukutywinwa kwiindawo zompom apho i-shaft idlula kwi-cover. Ubunzima obaneleyo bubunjwe ngokugxininisa ngamandla kwiindawo ezimbini - ukujikeleza kunye nokumiselwa. Amalungu kufuneka abe nokuchaneka okuphezulu, kufezwa ngokugaya nokugaya.

Izilwanyana zokumisela iimpompo ezinomileyo zithintela umbane ukungena kwindawo ejikelezile, kwaye kwiipompo ezingenakudlula, musa ukuvumela amanzi ukuba aqhubekele kwinjini, ngaloo ndlela ugweme isiphaluka esifutshane. Ukwandisa ukuchaneka kwi-shaft enye, kukho izibonda ezimbini usebenzisa i-dielectric (ioli okanye ukupholisa umzimba).

Icandelo elitywinwe linokulinganiswa, libe ne-cartridge okanye isakhiwo esingenakunyaniswa. Uxinzelelo olumanzi, uhlobo lwawo kunye nobushushu buchaphazela izinto ezinzima okanye ezithambileyo ezisetyenziswayo. Ukusabalalisa ngokubanzi kwatholakala i-alumina, igraphite kunye nokufakelwa, i-carbide. Njengesiqulatho sesibini, ukusetyenziswa kweerubha kunokwenzeka.

Indlela yokwandisa ubomi benkonzo

Kufuneka kuqatshelwe ukuba izinto ezinjalo zixhomekeke kwiingubo ezikhawulezayo kwaye zijongene nokusingqongileyo, kodwa nangona kunjalo, zona zichanekileyo. Uninzi lweengxaki ekusebenziseni iipompu zidibaniswa nokuchithwa kwesixhobo. Ubomi benkonzo buyancitshiswa ngenxa yezizathu ezininzi, umzekelo, ngenxa yempembelelo yeengqungquthela eziqhekezayo okanye ukushisa okuphakamileyo. Kuchaphazeleka nangokusetyenziswa kakubi. Ukuqinisekisa ukuba utywina lweempawu luhlala ixesha elide, kubalulekile ukukhetha ukwakhiwa okuhambisana nemisebenzi.

Iimvulsions kunye neoli azifanelekanga kwiirubha, njengoko kungenakunqandwa kwimveliso yokucoca. Kule meko, i-Viton isetyenziselwa ukuxubusha. Ukusebenza ngokukhawuleza, okubangela ukugqithisa, kunokukhokelela kumonakalo kwisixhobo. Ukukhutshwa komoya ngeendlela zokupasa iimpompo ezifunekayo.

Ixabiso elikhethekileyo lulungiso olulungelelanisiweyo lokuzenzekelayo. Kwakhona kunokwenzeka ukuba unamathele, apho iindiza zihlanganiswa ndawonye emva kwexesha elingenanto okanye i-rubber idibeneyo kwi-shaft. Ukuthintela ukuvimba, ngamanye amaxesha kuyimfuneko ukupheqa i-shaft.

Utywina kabini

Uluhlobo, izinto kunye nokwakhiwa kwetywina kuxhomekeka kwiimeko apho umsebenzi kunye neempawu ziselo lwamanzi okupompa zenzeka. Isitywina esisinye sisetyenziselwa utywala ezingenaziqhubi kunye nomlilo onobungozi, kunye nezixhobo eziqhubisayo zezigaba ze-T1, T2 kunye ne-T3.

Isitywina sibini sisetyenziselwa utywala olungafanelanga olunye. Ezi ziindawo ezinobungozi bendalo, ezinobungozi, eziyingozi okanye eziyingozi. Kuyafaneleka ukuba uqaphele ukuba phantsi kweemeko zokusebenza ezilukhuni, lo mlo usebenza ngokuphindwe kabini kunamanye. Ukongezelela, inxalenye yentsimbi yangaphakathi ayixhatshazelisi kwimpembelelo yendalo, kunye ne-thermoset, izihlwele ezixhamlayo zivalwe ngokukhawuleza ngaphandle kweendleko ezongezelelweyo.

Ngokuhambelana ne-GOST R 52743-2007, isitywina esicwangcisiweyo sesibini sisetyenziselwa ukusetyenziswa kwamanzi atyhafayo kwinqanaba le-T4. Imilinganiselo yokukhutshwa komonakalo, ixesha lokusetyenziswa kunye neendleko zokutywinwa ngokuphindwe kabini kuvumela ukukhetha kokugqibela.

Phakathi kweemfuno eziqhelekileyo zokumanyaniswa kwemigangatho yendlela yokuhambelana nokuhambelana nokuhamba kunye nobubanzi beepompo. Isakhiwo esiqhelekileyo kufuneka sinikeze imodeli yokusebenza yangaphambili kunye noxinzelelo oluphantsi kwetanki xa kuthelekiswa nomkhuhlane ukucatshiswa. Ukusetyenziswa kwesitywina esiphindwe kabini kuphelisa ithuba lokuvuza. Izinto eziphathekayo zezinto zomzimba mazizithobele ngokupheleleyo iimpawu zobuchwephesha zokusetyenziswa kwamanzi.

Umqobo weGesi

Kufana ne-cartridge ye-double seal, ngelixa igesi ye-inert isetyenziselwa ukupholisa kunye ne-lubricant, kunye nokuba endaweni yokuhlamba nge-jet yamanzi okanye ukupholisa amanzi. Inkqubo enjalo yasungulwa ngenxa yokuba ezinye zeendlela zokuqandwa ezisetyenzisiweyo kwangaphambili azikwazi ukusetyenziswa ngenxa yokungafani nemilinganiselo yokukhutshwa okuhlaziyiweyo.

Ukutywinwa kwendima yemingcele yegesi isebenzisa umoya ongenakonakalisa okanye i-nitrogen, evumela ukuthintela izinto ukungena kwindawo kwaye zihlangabezane nemigangatho yokukhangela. Kwiimeko ezifuna ukunyaniseka okwenyukayo, okanye xa kuthunyelwa amaqhinga enobungozi okanye obunobuthi, izakhiwo ezifunekayo kunye ne-gas grift double.

Ngendlela, intengo ephakathi (uphawu lwesitampu kunye nesithintelo segesi) malunga nama-ruble ayi-2 000.

Tandem

Imilinganiselo yendalo kunye nempilo ilawula ukusetyenziswa kwesithintelo sokutshintshwa kwezinto ezinjenge-hydrocarbons, i- carbon monoxide, i- vinyl chloride kunye nohlu olubanzi lwezinye iicomnogenic or compatile compounds.

Isixhobo esinjalo senza ukuba kunokwenzeka ukukhusela i-hydrocarbons ekhanyayo kunye neengxube ezibhekiselele kwiqondo lokushisa elingaphantsi kwinqanaba lomngcipheko wamanzi. Ipropanol kunye ne-methanol ziyimimiselo eqhelekileyo yemimiselo eneempawu ezixhamlayo. Kwakhona, i-tandem yandisa izinga lokuthembeka. Xa uyilo oluqhelekileyo luyehla, iqela langaphandle lithatha imisebenzi yokugcina.

Ngaphandle kwe-spinner

Ukuxhasa ukudibanisa kweeplanti zokutywinwa, akufuneki ukuhambisa isakhiwo kunye nomkhono okanye i-shaft. Phakathi kweenzuzo eziphambili kubaluleka ukugqamisa ukusebenza ngokubanzi lweqondo lokushisa kunye nokungabikho kwemfuneko yesetywina esongezelelweyo.

Umzuzu ongeyantlukwano yindlela yokuhlaziywa kwamacandelo ahlukeneyo xa isetyenziswe kwiimeko ezinzima.

Stalker

Ukuqinisekisa ukuba uqhagamshelwano lwee-unit, kufuneka udibanise isicatshulwa sesibini, eshukunywe ngaphaya kwe-axis ye-sleeve okanye i-shaft. Ngenxa yolu propati, umonakalo uyahlawulwa kwi-front front of the device. Iinzuzo zalo ziquka indleko ephantsi kunye nohlu olubanzi lwee-pushers, ezenziwe kwiivenkile kwiinkalo ezahlukeneyo kunye nobukhulu. Kodwa ku funeka kuqatshelwe ukuba kunokukhokelela ekumakaleni komonakalo kwi-bushing kunye nokunyuka kwetyikitya lesibini.

Izixhobo ezilinganisiweyo

Ukulinganisa itywina kubandakanya ukuguqulwa okulula kwesakhiwo, okunciphisa amandla omswakalo ovala uphawu lwe-shaft. Amanqanaba afanelekileyo ayahlukana nokukhululwa komlilo omncinci, umthwalo omncinci wokudibanisa iindiza kunye noxinzelelo olwandisiweyo. Ngenxa yoko, baba yinto ekhethekileyo yokudlulisa iingoma kunye noxinzelelo oluphezulu lwe-vapor kunye ne-lubricating capacity capacity.

Izinto ezingalinganiyo

Banokuzinza okukhulu xa beguqula i-cavitation kunye nokulungelelanisa, kunye nenani elincinci lokuvuza kunye neendleko eziphantsi. Inqanaba eliphantsi lokunyanzelisa uxinzelelo lugxininiso lwezakhiwo ezinjalo. Xa umda wokunciphisa umlinganiselo wokumisela ukulingana okwenziwa kwiindawo zokutywinwa kudlulile, ifilimu ephakathi kweendawo zifakwe ngaphandle kwaye umsebenzi ufumana uhambo olomileyo.

Umgangatho

Njengomzekelo, izilwanyana ze-Grundfos - mechanical, ezifuna ukunyuka kunye nokulungelelanisa kwi-bushing okanye shaft. Nangona indlela elula yokufaka ifowuni, iindleko zokugcinwa ngoku ziphambili, ezikhokelela ekuhanjisweni okukhulu kweendlela zeenqweloji.

Yangaphakathi

I-seal ye-Wilo yolu hlobo iyona ethandwa kakhulu. Kukhona inokwenzeka ukuba utshintsho olulula ukusekwa kwenkqubo yokuhlamba, ukulungelelanisa ukudlulisela uxinzelelo olongezelelweyo kwindalo. Kunconywa ukuba kusetyenziswe utywala obugwenxa nobunzima kunye neempawu ezaneleyo zokugcoba.

Cartridge

Olu hlobo luquka izilwanyana zokugqibela ezipompo ezifakwe kwi-hub, kuquka ne-sleeve ye-shaft kunye nebhokisi yengqungquthela enokutshatyalaliswa okufutshane kwi-shaft. Inzuzo yabo eyona nto ikukho kwi-intanethi yokuba akukho mfuneko yokusebenzisa izinto ezidibeneyo zokufakelwa kwazo. Ngenxa yokulolu hlobo, ubuchule beephene ngexesha lofakelo linciphile kwaye iindleko zokusebenza ziyancitshiswa .

Ongaphandle

Isityikitya esinjalo sesicatshulwa sibe yindlela enye yokuhlawula imali kwizinto ezincinci ezifunekayo ukwenzela ukunika uxinzelelo olusisigxina kwiimpawu zangaphakathi, ngaphandle kokuba kukho impawu ephezulu yokucoca. Enyanisweni, kuyafaneleka ukuphawula phakathi kwezinto ezingenakunceda ukunyanzeliswa kwamanzi kunye nefuthe lokutshatyalaliswa, oko kutheni iimpawu zolu hlobo zinemiqathango engaphantsi kwengcinezelo.
