Zeziphi ezinye izinto ezibalulekileyo ekufuneka ziqwalaselwe xa ukhetha imathiriyeli yokutywina echanekileyo yokufakwa kwesicelo?
Ixabiso elikhulu kunye nemibala efanelekayo
Ukufumaneka kwamatywina
Zonke izinto ezinefuthe kwinkqubo yokutywina: umz. uluhlu lobushushu, ulwelo kunye noxinzelelo
Zonke ezi zizinto ezibalulekileyo ekufuneka uziqwalasele kwinkqubo yakho yokutywina. Ukuba zonke izinto ziyaziwa, kuya kuba lula ukukhetha izinto ezifanelekileyo.
Kodwa into efunekayo kukuba izinto eziphathekayo kufuneka zihlale ixesha elide. Ngoko into yokuqala ekufuneka uyiqwalasele kukusebenza kobugcisa. Masiqale ngento yokusebenza.
Ubomi benkqubo kunye neendleko zizinto ezibalulekileyo (I-TIanjin Tanggu Water-Seal Valve Co., Ltd) ukucingela. Zonke izinto ziya kuchaphazela ukusebenza kwesicelo sakho. Kubalulekile ukuqwalasela imiba yoyilo ngokwesicelo. Oku kubandakanya izinto ezisetyenzisiweyo, iimilo zehardware kunye neenkqubo zokuvelisa. Kukwakho nemiba yokusingqongileyo ekufuneka iqwalaselwe kuquka: uxinzelelo, ubushushu, ixesha, indibano kunye nemidiya.
elastomer
Ii-elastomers zithandwa ngenxa yokuqina kwazo okulungileyo. Ayikho enye into enomgangatho ofanayo we-elasticity.
Ezinye izinto ezifana ne-polyurethanes kunye ne-thermoplastics zixhathisa kakhulu kuxinzelelo kune-elastomers.
Izinto zerabha zingasetyenziselwa kwiintlobo ezahlukeneyo zezicelo.
Iimpawu ezibalulekileyo zoomatshini ziquka
ukuqina
ubulukhuni
tensile strength
Ezinye iimpawu ezibalulekileyo ziquka
•Iseti yoxinzelelo
•ukumelana nobushushu
•ukuguquguquka kobushushu obuphantsi
•ukuhambelana kweekhemikhali
•Ukuchasa ukuguga
•ukuxhathisa kwe-abrasion
Eyona nto ibalulekileyo i-elasticity ye-rubber material. Masifunde ngakumbi ngale nto.
I-Elasticity sisiphumo sokuxhatshazwa. Iimathiriyeli ze-elastomeric, ezifana nerabha evulnisiweyo, ziya kubuyela kwimo yazo yantlandlolo ukuba ikhubazekile.
Izixhobo ze-inelastic, ezifana nerabha engavuthwanga, aziyi kubuyela kwimeko yazo yangaphambili ukuba zikhubazekile. Vulcanization (efanaivalve yebhabhathane ephindwe kabini) yinkqubo yokuguqula irabha ibe yimathiriyeli ye-elastomeric.
Ukhetho lwee-elastomers lusekwe ikakhulu:
•uluhlu lobushushu bokusebenza
•Ukumelana nolwelo kunye neegesi
•Ukumelana nemozulu, i-ozone kunye nemitha ye-UV
Ukhetho lwee-elastomers lusekwe ikakhulu:
•uluhlu lobushushu bokusebenza
•Ukumelana nolwelo kunye neegesi
•Ukumelana nemozulu, i-ozone kunye nemitha ye-UV
Imiba emithandathu ekufuneka iqwalaselwe xa kukhethwa izixhobo ezingaphezulu zokutywina ivalvu
Umphezulu wokutywina ngowona msebenzi ubaluleke kakhulu weivalve, umgangatho wokutywina uchaphazela ngqo ubomi benkonzo yeivalve, kunye nezinto eziphathekayo zokutywinwa yinto ebalulekileyo yokuqinisekisa umgangatho wokutywina. Ke ngoko, ezi zinto zilandelayo kufuneka ziqwalaselwe xa ukhetha imathiriyeli yokutywina ivalve:
①Ukumelana nokubola. "I-Corrosion" yinkqubo apho umphezulu wokutywina ubonakaliswe phantsi kwesenzo se-medium. Ukuba umphezulu wokutywina udlekile, ukusebenza kokutywinwa akunakuqinisekiswa, ngoko ke izinto ezibekwe kwindawo yokutywina kufuneka zixhathise i-corrosion. Ukuxhatshazwa kwe-corrosion of material ikakhulu kuxhomekeke ekubunjweni kwezinto kunye nokuzinza kwayo kweekhemikhali.
②Anti-abrasion. "Ukukrazula" kubhekiselele kumonakalo obangelwa kukukhuhlana kwezinto ngexesha lokuhamba okuhambelanayo kwendawo yokutywina. Olu hlobo lomonakalo ngokuqinisekileyo luya kubangela umonakalo kwindawo yokutywina. Ngoko ke, izinto zokutywina kufuneka zibe neempawu ezintle zokulwa nokukrala, ngakumbi kwiivalve zesango. Ukuchasana nokukrazula kwezinto kudla ngokugqitywa kwiimpawu zangaphakathi zezinto.
③Ukumelana nokhukuliseko. “Ukhukuliseko” yinkqubo yokutshabalalisa umphezulu wokutywina xa isiphakathi sihamba kwindawo yokutywina ngesantya esiphezulu. Olu hlobo lomonakalo lubonakala ngakumbi kwiivalve ze-throttle kunye neevalvu zokhuseleko ezisetyenziselwa ukushisa okuphezulu kunye noxinzelelo oluphezulu lweendaba zomoya, kwaye zinempembelelo enkulu kumonakalo wokutywinwa kokusebenza. Ke ngoko, ukuxhathisa ukhukuliseko yenye yeemfuno ezibalulekileyo zokutywina izixhobo ezingaphezulu.
④Kufuneka ibe nobunzima obuthile, kwaye ubunzima buya kuhla kakhulu phantsi kobushushu obuchaziweyo bokusebenza.
⑤I-coefficient yokwandiswa komgca wokutywinwa kwendawo yokutywina kunye nempahla yomzimba kufuneka ifane, eyona nto ibaluleke kakhulu kwisakhiwo sendandatho yokutywina, ukwenzela ukuba ugweme uxinzelelo olongezelelweyo kunye nokukhulula kwiqondo lokushisa eliphezulu.
⑥Ukusetyenziswa phantsi kweemeko eziphezulu zokushisa, kufuneka kubekho i-anti-oxidation eyaneleyo, ukuxhathisa ukukhathala kwe-thermal kunye nemiba yomjikelezo we-thermal.
Ngaphantsi kweemeko zangoku, kunzima ukufumana indawo yokutywina ehambelana ngokupheleleyo neemfuno ezingentla. Sinokugxila kuphela ekufezekiseni iimfuno zemiba ethile ngokweentlobo ezahlukeneyo zevalve kunye nokusetyenziswa. Ngokomzekelo, iivalve ezisetyenziswe kwimidiya ye-high-speed kufuneka zihlawule ngokukodwa kwiimfuno zokumelana nokukhukuliseka kwendawo yokutywinwa; kwaye xa i-medium iqulethe ukungcola okuqinileyo, izinto ezingaphezulu zokutywina ezinobunzima obuphezulu kufuneka zikhethwe.
