Amalungu okwandisa irabha adlala indima ebalulekileyo kwizicelo ezininzi zamashishini ezifuna ukuguquguquka kunye nokuhamba kweenkqubo zemibhobho.Zisetyenziselwa ngokubanzi ukuhlawulela ukwanda kwe-thermal, ukungcangcazela kunye nokungahambi kakuhle, ukuqinisekisa ukusebenza kakuhle kunye nokuthintela umonakalo kwiinkqubo zemibhobho.Nangona kunjalo, ukukhetha ijoyinti efanelekileyo yokwandisa irabha kwisicelo sakho kubalulekile ekuqinisekiseni ukusebenza kwayo kakuhle kunye nobomi benkonzo.Kweli nqaku, sixoxa ngezinto ezibalulekileyo ekufuneka ziqwalaselwe xa ukhetha ijoyinti yokwandiswa kwerabha.

1. Ubushushu kunye noxinzelelo
Enye yeengcamango eziphambili ekukhetheni i-rubber yokwandisa i-rubber yiqondo lokushisa kunye neemeko zoxinzelelo eziya kumelana nazo.Amalungu okwandisa irabha enzelwe ukumelana noluhlu lwamaqondo obushushu kunye noxinzelelo.Ke ngoko, kubalulekile ukwazi ubushushu obuphezulu kunye nobuncinci kunye noxinzelelo oluya kudibana noludibeneyo ukuze kuqinisekiswe ukuba lilinganiswe ngokufanelekileyo.Ukungaphumeleli ukukhetha ukulinganisa okuchanekileyo kunokubangela ukungaphumeleli kwangaphambi kwexesha lokudibanisa kunye nomonakalo onokuthi ube khona kwinkqubo yonke.

2. Iimfuno zesenzo
Amalungu okwandisa irabha athatha i-axial kunye nentshukumo yecala kwiinkqubo zemibhobho.Ngaphambi kokukhetha i-joint yokwandisa irabha, kubalulekile ukumisela ukunyakaza okulindelekileyo kunye nokufuduka okuya kwenzeka kwinkqubo.Oku kubandakanya izinto ezifana nokujikeleza kwe-angular, i-axial compression kunye ne-lateral deflection.Ngokuvavanya ngokuchanekileyo iimfuno zokunyakaza, unokukhetha amajoyina athatha ngokufanelekileyo kwaye ahlawule ukunyakaza okulindelekileyo, ukuthintela uxinzelelo kwinkqubo yakho yombhobho.

3. Ukuhambelana okuphakathi
Amalungu okwandisa irabha ayenziwe kwizinto ezahlukeneyo ezinokumelana neekhemikhali ezahlukeneyo.Kubalulekile ukuqwalasela i-media ejikelezayo kwi-joint yokwandisa kunye nokuqinisekisa ukuhambelana nezinto zerabha.Imichiza ethile okanye ulwelo lusenokonakalisa uhlobo oluthile lwerabha, lubangele ukusilela kwangaphambi kwexesha.Ukwazi ukubunjwa kweekhemikhali ze-medium kunye nokukhetha i-rubber material enganyangekiyo kwisenzo esinokonakala esinokwenzeka kubaluleke kakhulu kubomi obude kunye nokuthembeka kokubambisana kwandiso.

4. Ukwakhiwa kunye nokuqiniswa
Izicelo ezahlukeneyo zifuna ulwakhiwo oludibeneyo lwerabha olwandisiweyo kunye neentlobo zokuqinisa.Zinokuba yi-arch enye okanye uyilo lwe-arch eninzi, nganye inikezela ngamanqanaba ahlukeneyo okufunxa okushukumayo kunye nokuguquguquka.Ukukhethwa kwezinto zokuqinisa (ezifana nendwangu okanye isinyithi) kufuneka kusekelwe kwiimfuno ezithile zesicelo.Amalungu aqiniswe ngamalaphu afanelekile kuxinzelelo oluphantsi kunye nokunyakaza okuthambileyo, ngelixa iintsimbi eziqiniswe ngentsimbi zingcono kwiingcinezelo eziphezulu kunye nokunyakaza okukhulu.

5. Umgangatho kunye nesiqinisekiso
Xa ukhetha ijoyinti yokwandisa irabha, kubalulekile ukuqwalasela isidima somenzi, amava kunye nemigangatho yomgangatho.Ukukhetha umenzi othembekileyo kuqinisekisa ukuba ufumana imveliso ehlangabezana nemigangatho yoshishino kwaye iye yavavanywa ngokuqatha.Isiqinisekiso esivela kwimibutho eyaziwayo efana ne-ISO okanye i-ASTM ibonelela ngengqinisekiso eyongezelelweyo yomgangatho kunye nokusebenza kwamalungu okwandisa irabha.

Ukuqukumbela, ukukhetha umdibaniso ofanelekileyo wokwandisa irabha kufuna ukuphononongwa ngononophelo lobushushu kunye neemfuno zoxinzelelo, ulindelo lwentshukumo, ukuhambelana kwemidiya, ulwakhiwo, ukuqinisa kunye nodumo lomenzi.Ngokuqwalasela le miba, unokukhetha ijoyinti yokwandisa irabha ehlangabezana neemfuno zakho ezithile, ukuqinisekisa ukusebenza okuthembekileyo nokusebenzayo kwenkqubo yakho yombhobho.
