Uphawu lokukhanda. Double uphawu mechanical: Standard

I mechanical uphawu inhlangano isetshenziselwa uphawu izingxenye futha lapho shaft sidlula ikhava. kwakhiwa ukuminyana eyanele enamandla ngokucindezela we evele of izakhi ezimbili - umile futhi ukuphotha. Izinto kumele abe ukunemba okuphezulu, ke ibangelwa ethi awafike futhi wokucwebezelisa.

seal Mechanical ngoba amaphampu uhlobo ezomile ukuvimbela ketshezi angene imvelo hhayi motor ngwenya sidlulile emanzini, ukugwema okuvela short circuit. Ukuze kwandiswe ukucacisa ku umgodi uphawu olulodwa elise usebenzisa Kwe-dielectric Heating ezimbili (uwoyela noma kokupholisayo mass).

Umhlangano uphawu kungenziwa ukulinganisela ukuze abe igobolondo noma isakhiwo egoqekayo. ingcindezi Fluid, uhlobo lokushisa kuthinte sebenzisa izinto kanzima noma soft. Itholiwe okwandile alumina, graphite elifakwe Carbide. Njengoba kophawu yesibili zingasebenzisa zenjoloba.

Kanjani ukunweba ukuphila

Kumele kuqashelwe ukuthi lezi zinto angaphansi bafake ngokushesha futhi ukuzwela ezahlukene imvelo, kodwa naphezu kwale mizamo, kukhona inembe kunazo. Iningi nobunzima emsebenzini amaphampu elihlobene ne-ukuhlukaniswa idivayisi wathi. Impilo inkonzo kuyehla ngenxa yezizathu ezithize, isib, ngenxa yokuchayeka izinhlayiya olwalwenza noma okushisa aphakeme. Futhi ithinta kabi. Ukuze uphawu mechanical ihlala isikhathi eside, kubalulekile ukuba ukhethe ukwakheka elihambisana umsebenzi.

Emulsions futhi amafutha ayifanele iraba, ngoba akuwona uzinze emikhiqizweni ye uwoyela. Kulesi simo isetshenziselwa Viton uphawu. ukugijima Dry itshe esivivaneni okweqile, kungabangela ukulimala kudivayisi. Kudinga Ukubonakalisa ehlelekile ngokusebenzisa okukhiphayo futha isethi.

Okubaluleke kakhulu yiyona abanekhono kulungiselelwa othomathikhi. Futhi kukhona kungenzeka yokunamathela, lapho indiza ethe njo ngemva amathayi ingenzi lutho noma soldered le kushaft. Ukuvimbela clumping ngezinye izikhathi kudingekile ukupheqa kushaft.

uphawu double

Uhlobo impahla kanye uphawu design zincike esimweni lapho indawo umsebenzi kanye nezici eziwuketshezi. uphawu Single isetshenziselwa uketshezi, non-obhubhisayo oluvuthayo kanye alufakwa izinto izigaba T1, T2 kanye T3.

uphawu Double esetshenziselwa uketshezi elingalingani olulodwa. Lokhu compounds imvelo enobungozi, ezinobuthi, impahla ezonakalisayo noma athile. Kuyinto ephawulekayo ukuthi lo mshumayeli design usebenza ngaphansi kwezimo ezinzima kahlanu kunonyaka nezinye. Ngaphezu kwalokho, metal okuyingxenye kwalo amelana amathonya kwemvelo, futhi thermosetting, mass viscous uphawu ngokushesha ngaphandle kwezindleko ezingeziwe.

Ngokuhambisana GOST P 52743-2007, kabili uphawu mechanical esetshenziselwa uketshezi enobungozi T4 isigaba. amazinga Emission uma umonakalo, inkathi yokusetshenziswa kanye nezindleko uphawu ezimbili evumela ukuba senze ukukhetha sokugcina.

Phakathi nezidingo jikelele ngokuba uphawu mechanical kuyafaneleka ukuhambisana indiza Ubukhulu iphampa. isakhiwo Jikelele kufanele ahlinzeke imodi wangaphambili wokusebenza mass ngomfutho ongaphakeme echibini njengoba kuqhathaniswa medium uphawu. Isicelo seal double aqede kungenzeka ukuvuza. Indaba for the izakhi izindlu kufanele uhambisane ngokugcwele izici zobuchwepheshe uketshezi ngcono.

igesi isithiyo

It sifana ezimbili uphawu igobolondo, lapho njengoba Ukupholisa igrisi futhi igesi engaxubani namakhemikhali isetshenziswa, futhi esikhundleni ugeza ngamanzi jet noma coolants. uhlelo ezinjalo yasungulwa Ngenxa yokuthi ezinye izingoma isithiyo angaphambilini ingasetshenziswa hhayi ngenxa lokungafani olusha nezindinganiso ekushayweni.

Seals endimeni igesi isithiyo ayinangozi ukusetshenziswa emoyeni noma nitrogen, ukuvumela ukuvimbela ingress izinto zibe imvelo futhi uhambisane namazinga amukelekile ekushayweni. Nakuba usezimweni ezidinga ukuba nokwethenjelwa yanda, noma ukuthuthwa compounds eziyingozi noma enobuthi ozofakwa ukwakha double igesi isithiyo.

By the way, isilinganiso senani (uphawu mechanical nge isithiyo igesi) - ruble mayelana 2000.

Ngohlelo

Amazinga lokuvikela imvelo kanye nempilo Ngohlelo zilawula ukusetshenziswa izinto uzotshala, ezifana hydrocarbon, i-carbon monoxide, vinyl chloride futhi nohlu olubanzi lwezinhlangano umdlavuza noma ezinye compounds oluyingozi.

Leli lungiselelo kuvimbela Uqweqwe ukukhanya uhlobo hydrocarbon futhi uketshezi, izimpawu nokuncipha lokushisa ngaphansi kwezinga-qhwa yamanzi. Propanol kanye methanol izibonelo ejwayelekile compounds kokuba sesikhashana izakhiwo. Futhi Ngohlelo kwandisa nokwethenjelwa. Uma wephula ezivamile design ingxenye engaphandle eqala imisebenzi yesondlo.

ngaphandle stripper

Ukuze sisekele evele contact uphawu ukunyakaza engathandeki isakhiwo emikhonweni noma shaft. Phakathi izinzuzo main ukunikeza operability phezu ububanzi lokushisa ububanzi futhi asikho isidingo ukusebenzisa ukubekwa uphawu ezengeziwe.

torque engu Negative ithuthukela lwezigaba engu- ukusetshenziswa ezindaweni nokhahlo.

Jogger

Ukuqinisekisa evele contact ISIZINDA iyadingeka ukuxhuma secondary uphawu mechanical, ezithathekayo kanye eksisi emikhonweni noma shaft. Ngenxa enjalo offset ukulimala kwempahla ngezihluthu indiza. Izinzuzo zihlanganisa eziphansi kanye ububanzi sasivumela olubanzi tappets, owethulwa ezitolo ezihlukahlukene ukucupha nosayizi. Kodwa kufanele kuphawulwe ukuthi kungabangela umonakalo ukugqwala we emikhonweni kanye ukufuduka kophawu yesibili.

amadivaysi olinganiselayo

I okulinganisa kophawu kuhlanganisa umklamo ukuguqulwa elula ukuthi kunciphisa amandla wokubacindezela esivala mechanical kushaft uphawu. Olinganiselayo ezahlukene Kwabiwa amayunithi lemali encane ukushisa, i-viral load elincane evele uphawu nokukhuphula degree of ingcindezi. Ngenxa yalesi baba omunye elikhulu ukuthuthwa compounds nge high umusi ingcindezi kanye enganele yezihlanganisi ikhono.

izakhi ongenakulinganisela

Sinenkosi ukuzinza enkulu lapho beshintsha cavitation kanye nokuqondanisa nge inani elincane ukuvuza kanye eziphansi. Ngokwanele ongaphakeme ingcindezi esiteji kuyinto embi ngamacebo ezinjalo. Lapho edlula umngcele set yokucindezela inzuzo nomphumela esebenza engxenyeni ukubekwa uphawu elise phakathi evele of ifilimu extruded, futhi umsebenzi uthola ukugijima ezomile.

ejwayelekile

Njengoba isibonelo Grundfos - lwezimpawu mechanical ezidinga ukufakwa kanye nokuqondanisa emtapwei noma shaft. Naphezu indlela okulula ukufakwa kudivayisi, ke okwamanje igunya ukwehla nokugcinwa izindleko, kuphumele ukusabalala enkulu igobolondo-imiklamo.

yangaphakathi Single

Wilo uphawu mechanical lolu hlobo ithandwa kakhulu. Kungenzeka ukushintsha ukukhanya ukwakha ukugeza uhlelo sesikhashana ngoba silinganisa ingcindezi-ngokudlulisela imvelo kuma. Kunconywa ukusebenzisa i-uketshezi nolaka futhi okungezona ngendlela enobudlova lubricating izakhiwo okwanele.

igobolondo

Lesi sigaba sihlanganisa lwezimpawu mechanical ngoba amaphampu ogibele ihabhu kuhlanganise emikhonweni ku shaft futhi ikhava ukugxusha ibhokisi kokuba ngumuntu okwaziyo Friend le kushaft. Ingabe inzuzo yabo eyinhloko ukuthi asikho isidingo ukusebenzisa lokukhuphula izakhi yokuxhuma. Ngenxa ukwakhiwa okunjalo kunciphisa amathuba amaphutha ngesikhathi sokufaka futhi yehlise izindleko zokugcina.

olulodwa yangaphandle

uphawu okunjalo mechanical iba isabelomali okunye esikhundleni of izinsimbi ezibizayo, okuyinto edingekayo ukuze lidlulisele ukugqwala ukumelana lwezimpawu yangaphakathi, kuncike ukutholakala ukusebenza high e nolaka yezihlanganisi eziwuketshezi. Nokho, kufanele nemiphumela ethile engathandeki phakathi ukuchayeka ingcindezi wokubacindezela nethonya uthuthumele, ngenxa okuyinto uphawu lolu hlobo babe ingcindezi encane ngaphandle waphawula.
