Ijoyinti Yerabha

1. Iyini ijoyinti yerabha? Uyini umsebenzi wayo ezinhlelweni zamapayipi?

Amajoyinti enjoloba, aziwa nangokuthi amajoyinti athambile enjoloba kanye namajoyinti enjoloba aguquguqukayo, ayizinto ezixhumanisayo eziguquguqukayo ezifakwe phakathi kwamavalvu namapayipi. Imisebenzi yawo eyinhloko ifaka amaphuzu amane: ukunciphisa ukudlidliza kanye nokunciphisa umsindo - ukumunca ukudlidliza kanye nomsindo womshini okhiqizwa ukusebenza kwamaphampu amanzi, ama-compressor kanye neminye imishini; isinxephezelo sokufuduka - ukugaya ukwanda kwe-axial kanye nokubhidlika kanye nokususwa kwepayipi eceleni ngenxa yokwanda nokuncipha kokushisa; ukukhululeka kwengcindezi - ukuvikela amavalvu namapayipi ekulimaleni kwamandla angaphandle; ukulula kokufakwa - ukuvumela iphutha elithile lokufakwa kanye nokunciphisa izidingo ze-coaxiality yepayipi.

2. Yiziphi izinhlobo eziyinhloko zesakhiwo samajoyinti enjoloba?

Kunezinhlobo ezintathu ezivamile: i-single sphere (eguquguqukayo kakhulu, efanelekile ekunciphiseni ukudlidliza okuvamile kanye nesinxephezelo sokufuduka), njengoba kuboniswe kuMfanekiso 01; i-double sphere (isinxephezelo esikhulu, esifanelekile ngezikhathi ezinkulu zokufuduka), njengoba kuboniswe kuMfanekiso 02; i-reducing joint (esetshenziselwa ukuxhuma amapayipi anobubanzi obuhlukene), njengoba kuboniswe kuMfanekiso 03, indlela yokuxhuma ekugcineni ihlukaniswe ngohlobo lwe-flange (ukuxhumeka kwe-bolt ne-valve flange) kanye nohlobo lwe-clamp (ukuxhumeka okusheshayo).

3. Ungakhetha kanjani izinto zerabha ngokwezimo zokusebenza?

Irabha yemvelo ifanelekela izindawo zokushisa ezijwayelekile njengamanzi nomoya; irabha ye-nitrile inokumelana okuhle kakhulu namafutha futhi ifanelekela izindawo zokushisa eziqukethe uwoyela kanye namapayipi kaphethiloli; irabha ye-EPDM imelana ne-ozone, imelana nesimo sezulu, imelana ne-asidi kanye ne-alkali, futhi isetshenziswa kabanzi emapayipini angaphandle namakhemikhali; irabha yerabha/i-silicone ye-fluorine isetshenziswa ngokukhethekile ezindaweni zokushisa eziphakeme (kufika ku-200°C noma ngaphezulu) noma ezindaweni zokushisa ezigqwala kakhulu. Ukukhetha izinto ezingalungile kuzokwenza ukuthi ilunga livuvuke, liqhekeke noma lithambe ngokushesha.

4. Yiziphi izinyathelo zokuphepha ezibalulekile ngesikhathi sokufakwa?

Okokuqala:Ubude bokufaka kumele buhambisane nobude obujwayelekile bomkhiqizo, futhi ukwelula noma ukucindezela ngokweqile akuvunyelwe (iphutha elivamile ukwelula imbobo ngenkani ukuze ifakwe, okuzonciphisa kakhulu impilo yesevisi);

Okwesibili:Amabholti kudingeka aqiniswe ngokulinganayo ngokuvundlile ukuze kugwenywe umonakalo ongaphelele obangelwa ukuthambekela;

Okwesithathu:Uma ifakwa endaweni yokuphuma kwephampu yamanzi, kufanele ibekwe ohlangothini olungezansi lwevalvu ukuze kugwenywe ukushayisana kwesando samanzi;

Okwesine:kufanele igcinwe kude nemithombo yokushisa kanye nemithombo ye-ozone (njengezinhlansi zemoto kanye nemisebenzi yokushisela);

Okwesihlanu:Akuvunyelwe ukusetshenziswa kumapayipi e-vacuum. Ngaphandle kokuthi kusetshenziswe i-negative pressure joint ekhethekile ene-skeleton yensimbi, ibhola lingase lisikwe libe yi-flat.

5. Ungabona kanjani ukuthi ijoyinti yerabha idinga ukushintshwa nini?

Kufanele ishintshwe ngokushesha uma kwenzeka noma yiziphi zezimo ezilandelayo: kukhona imifantu esobala, amabhamuza noma ukuguquka ebusweni; ukuvuza kokuvala i-flange kanye nokuqina kwayo akuphumelelanga; irabha iba lukhuni futhi ilahlekelwa ukunwebeka (akukho sibonakaliso sokubuyela emuva uma icindezelwa ngozipho); isikhathi senkonzo esiphawulwe kumkhiqizo sidlula (ngokuvamile iminyaka emi-5 kuya kwengu-8). Kunconywa ukwenza ukuhlolwa okuvamile, ikakhulukazi ezindaweni ezibalulekile njengezindawo zokufaka amanzi kanye nokuhlinzekwa kwamanzi ezakhiweni eziphakeme.

6. Isiphetho

Amajoyinti enjoloba anesibopho sokuxhumana okuguquguqukayo nokuvikelwa, kanyeI-TWSbanesibopho sokulawula okunembile kanye nokuvinjelwa kokugeleza kwamanzi. Kuphela uma lokhu kokubili kuhlanganiswa, uhlelo lwamapayipi luzophelela futhi luthembeke. Uma ukhetha ivalvu, khethaI-TWS—amavalvu ebhabhathane, amavalvu esango, futhiama-valve okuhlola, konke endaweni eyodwa! Siyakwamukela ukusishayela ucingo ukuze sithole ukubonisana nokuthenga.
