Kunezimbangela ezine ezijwayelekile zokwehluleka kweizimpawu zenjoloba: amaphutha edizayini, amaphutha okukhetha impahla, izindaba zekhwalithi yophawu, nokusetshenziswa okungafanele.
1. Amaphutha edizayini ngokuvamile abangelwa abaklami abangawuqondi ngokwanele umkhiqizo.
Isibonelo, ukulinganisa okunganele kwengcindezi ethwalwa isici sokuvala, ukuqonda okungalungile kokusatshalaliswa kwengcindezi yokuxhumana endaweni yokuvala, kanye nomklamo ongenangqondo wegroove yokubeka isici sokuvala.Ukuhlaziywa kwe-Finite element (FEA) kuvame ukusetshenziselwa ukusiza ekuhlaziyeni nasekuhlulekeni kweizimpawu.
2. Iphutha lokukhetha impahla
Izinto ezijwayelekile zokuvala injoloba zifaka i-EPDM, i-NBR, i-VMQ, i-FKM, ne-CR.Lawa ma-rubber anezici ezihlukene kanye nezicelo.Ukukhethwa kwezinto ezibonakalayo kufanele kucatshangelwe ezicini eziningi, ezifana nezinga lokushisa lokusetshenziswa, noma ngabe impahla imelana nendawo, ubulukhuni bezinto ezibonakalayo, ukucindezelwa kwe-deformation unomphela, nokumelana nokugqoka.
Amaphutha okukhethwa kwezinto avame ukubangelwa ukuthi abaklami abajwayele ukusebenza kwezinto ezihlukahlukene.Umphakeli onolwazi lwerabha seal angakhomba izinkinga zokukhetha izinto kusukela ekuqaleni.
3. Ikhwalithi yophawu
Izinga lokukhiqizwa kwezimvu zamanzi lihlobene eduze nokuthembeka komkhiqizo wokugcina.Izinkinga ezivamile zihlanganisa ikhwalithi yempahla eluhlaza engazinzile, ukuphakelwa okungalungile kwezinto zokusetshenziswa ngesikhathi sokuxuba iraba, ukugcinwa okungalungile kwezinto ezingavuthiwe noma irabha exubile (ukungcola okuphambene), ukuxubana okungalingani kwezinto zenjoloba, izimo ezingalungile zokuvuthwa (izinga lokushisa, isikhathi, ingcindezi, njll.), ukugcinwa okungalungile kwemikhiqizo yokuvala, kanye nokusetshenziswa okungalungile kwesikhunta.Lezi zinkinga zivame ukubandakanya ukulawulwa kwekhwalithi kunqubo yokukhiqiza.Iqembu eli-odayo kufanele lenze ukuhlola okuningi, ucwaningo, nokuhlola umkhiqizo lapho kukhethwa umkhiqizi wengxenye yokuvala.Ngesikhathi senqubo yokuhlinzeka, umenzi wophawu angadingeka futhi ukuthi anikeze umbiko wokuhlola weqiniso nonembile.
4. Ukusetshenziswa okungalungile kwezimpawu
Uphawu oluhle, uma lusetshenziswe ngendlela engafanele, lungabangela ukuthi wonke umkhiqizo ungaphumeleli, njengokusetshenziswa okungalungile kwamafutha okugcoba.
Enye inkinga evamile amaphutha okufaka.Isibonelo, ukuhlanekezela kwenzeka ngesikhathi somhlangano we-O-ring;Ukucindezelwa okungalingani kwesici sokuvala ngenxa yokufakwa okungalungile;Ukugcotshwa okunganele kwezimpawu kanye namanye amaphutha.Uma lawa maphutha ebangelwa umenzi wezimpawu, khona-ke lokhu kubhekwa njengendaba yekhwalithi yokukhiqiza
