I-Rubber Expansion Joint

Ukwandiswa kwerabha edibeneyo, ekwaziwa ngokuba yi-rubber joint, luhlobo lolwandiso lwejoyinti

1. Izihlandlo zokufaka isicelo:

Umdibaniso wokwandiswa kwerabha kukudityaniswa okuguquguqukayo kwemibhobho yentsimbi, equlunqwe yingqukuva yerabha eqiniswe ngongqimba lwangaphakathi lwerabha, ilaphu lentambo yenayiloni, umaleko werabha wangaphandle kunye neflange yentsimbi. Ineempawu zokumelana noxinzelelo oluphezulu, ukuqina okuhle, ukufuduswa okukhulu, ukutenxa kombhobho olungeleleneyo, ukufunxa ukungcangcazela, isiphumo esihle sokunciphisa ingxolo kunye nofakelo olufanelekileyo; Inokusetyenziswa ngokubanzi kunikezelo lwamanzi kunye nokuhanjiswa kwamanzi, ukujikeleza kwamanzi, i-HVAC, ukukhuselwa komlilo, ukwenza iphepha, i-pharmaceutical, i-petrochemical, inqanawa, impompo yamanzi, i-compressor, i-fan kunye nezinye iinkqubo zemibhobho.

2.Indlela yokugcina ijoyinti yokwandisa irabha:

Isixhobo salo sokuhambisa simisela ubomi bokwandiswa kwerabha. I-Corrosive acids, iziseko, i-oyile kunye neekhemikhali zinefuthe kwi-powder kwindawo eqinileyo, isinyithi kunye ne-steam kwi-gas. Zingasetyenziselwa ukutshintsha izinto eziphathekayo zokulawula imidiya eyahlukeneyo yokuhambisa, oko kukugcina i-valve ngeengxaki zezinto eziphathekayo. Iingxaki zokufakela Ngexesha lokufakela, indawo yokufakela iya kubonakaliswa elangeni, eya konakalisa irabha kunye nobudala, ngoko ke kuyimfuneko ukugubungela i-rubber yokwandisa i-rubber kunye nefilimu ye-sunscreen. Ngokufakela, i-rubber yokwandisa i-joint ngokwayo inokufakelwa kokuphakama okuphezulu, kwaye imfuneko yoxinzelelo inkulu kakhulu, ngoko i-rubber yokwandisa i-rubber ingafakwa ngeli xesha. Ezi ndlela zimbini zisebenzisa amandla angaphandle ukugcina ijoyinti yokwandisa irabha. Ngethuba lokusebenza, xa i-joint yokwandisa i-rubber ifakwe ekusebenzeni, kuyimfuneko ukujonga rhoqo ukunyanzeliswa kwe-bolt yecandelo lofakelo lwe-joint yokwandisa irabha. Ukuba isetyenziswe ixesha elide, i-screws iya kugqwala kwaye iphule, ngoko kufuneka itshintshwe. Le ndlela yokulondoloza yeyokutshintshwa kwamacandelo amancinci, anokugcina ubukhulu becala amacandelo amakhulu.

3. Indlela yokufakela:

Imodeli, inkcazo kunye nokulungelelaniswa kwemibhobho yejoyinti yokwandisa iya kujongwa phambi kofakelo ukuqinisekisa ukuba iyahlangabezana neemfuno zoyilo. Kwijoyinti yokwandiswa kunye nomkhono ongaphakathi, kuya kuqatshelwa ukuba isalathiso somkhono ongaphakathi siya kuhambelana necala lokuhamba kwe-medium, kunye ne-hinge ejikelezayo indiza yohlobo lwehinge yolwandiso lwejoyinti iya kuhambelana nenqwelomoya yokujikeleza. Kwimbuyekezo efuna "ukuqina okubandayo", izixhobo ezincedisayo ezisetyenziselwa ukuguqulwa kwangaphambili aziyi kususwa kude kube kufakwe umbhobho. Akuvumelekanga ukulungelelanisa ukufakwa ngaphandle kokunyamezela kombhobho ngokuguqulwa kwejoyinti yokwandisa i-corrugated, ukwenzela ukuba ingachaphazeli umsebenzi oqhelekileyo we-comensator, ukunciphisa ubomi benkonzo kunye nokwandisa umthwalo wenkqubo yombhobho, izixhobo kunye namalungu axhasayo. . Ngexesha lofakelo, i-welding slag ayivumelekanga ukuba itshize kumphezulu wecala lamaza, kwaye i-wave case ayivumelekanga ukuba ihlupheke komnye umonakalo womatshini. Emva kokuba inkqubo yombhobho ifakwe, amacandelo ancedisayo okubeka kunye nezibophelelo ezisetyenziselwa ukufakela kunye nokuthutha kwi-joint yokwandiswa kwamalahle ziya kususwa ngokukhawuleza, kwaye isixhobo sokumisa siya kulungelelaniswa kwindawo echaziweyo ngokweemfuno zoyilo, ukuze inkqubo yombhobho inomthamo owaneleyo wembuyekezo phantsi kweemeko zokusingqongileyo. Izinto ezihambayo zejoyinti yokwandisa aziyi kuvalwa okanye zithintelwe ngamacandelo angaphandle, kwaye ukusebenza okuqhelekileyo kwendawo nganye ehambayo kuya kuqinisekiswa. Ngethuba lovavanyo lwe-hydrostatic, ukuxhaswa kombhobho wesibini osisigxina kunye nokuphela kombhobho odibeneyo wokwandisa uya kuqiniswa ukukhusela umbhobho ukuba uhambe okanye ujikeleze. Kwi-comensator kunye nepayipi yayo yokudibanisa esetyenziselwa i-gas medium, qaphela ukuba ngaba kuyimfuneko ukongeza inkxaso yesikhashana xa ugcwalisa amanzi. Umxholo we-ion we-96 wesisombululo sokucoca esisetyenziselwa uvavanyo lwe-hydrostatic awuyi kudlula i-25PPM. Emva kovavanyo lwe-hydrostatic, amanzi aqokelelweyo kwiqokobhe lamaza aya kukhutshelwa ngokukhawuleza kwaye umphezulu ongaphakathi weqokobhe lamaza uya kuvuthelwa wome.

4. Iimpawu zejoyinti yokwandisa irabha:

Amalungu okwandisa irabha asetyenziswa ngaphambili nangasemva kwimpompo yamanzi (ngenxa yokungcangcazela); Ngenxa yezixhobo ezahlukeneyo, irabha inokufikelela kwiziphumo ze-asidi kunye nokumelana ne-alkali, kodwa ubushushu bokusetyenziswa kwayo ngokuqhelekileyo bungaphantsi kwe-160 ℃, ngakumbi ukuya kuma-300 ℃, kwaye uxinzelelo lokusetyenziswa alukhulu; Amalungu aqinileyo awanayo i-asidi kunye nokumelana ne-alkali. Ezikhethekileyo zingenziwa ngensimbi engenasici. Ubushushu bokusebenza kunye noxinzelelo luphezulu kunezo zokwandiswa kwerabha. Amalungu okwandisa irabha anexabiso eliphantsi kunamalungu aqinileyo. Kulula ukuzifaka ngasentla; Ijoyinti yokwandiswa kwerabha isetyenziselwa kakhulu ukunciphisa ukungcangcazela kombhobho.
