Ungahlola kanjani futhi ulungise izimpawu ze-polyurethane ezinezakhiwo ezinhle kakhulu?
Izigxivizo ze-polyurethane zenziwe ngerabha ezinezici ezilandelayo ezinhle kakhulu:
Izigxivizo ze-polyurethane zinokunwebeka okuhle kakhulu, ukumelana nokugqoka, ukumelana nowoyela, ukumelana nokubanda namandla aqinile, kodwa ukumelana namanzi, ikakhulukazi ukumelana ne-alkali, kubi.Atholakala ngezinhlobo ezishisayo ze-vulcanised, izinga lokushisa legumbi eline-vulcanised kanye nezinhlobo ezincibilikayo ezishisayo.Uhlobo lwe-vulcanisation lokushisa kwegumbi luhlukaniswe ingxenye eyodwa kanye nezingxenye ezimbili.Zisetshenziswa kakhulu ekuvaleni izinto ezakhiweni nasekuvaleni ekwakhiweni kwezimoto.
Ukutholwa nokugcinwa kwe-polyurethane O-rings (izici): hlola ukuthi izingxenye zokulawula i-hydraulic azinawo amaphutha, futhi umsebenzi wokulungisa ungena endaweni eyimpumputhe isikhashana.Hlukanisa futhi uhlole isilinda longitudinal yesibambi samathuluzi, uthole ukuthi isiyingi sikawoyela se-piston “O” seal sangaphandle siphansi, ngesikhathi esifanayo sathola ukuthi usayizi we-piston wangaphandle wombuthano awuhlangabezani nezidingo (izizathu zokukhiqiza ithuluzi lomshini) , isiqondiso sobubanzi singaphansi kosayizi ojwayelekile ongu-0.8MM, ukuphuma komzimba kwe-piston nesilinda kukhulu kakhulu, okuholela ku-cylinder ye-longitudinal cavity uwoyela oshintshashintshayo.Ukunakekelwa lapho kufakwa esikhundleni sepiston efanelekayo kanye “nohlobo lwe-O” kuvalwa ngemva kokuba ithuluzi lomshini lishaya ukuxazulula inkinga.Ukuhlaziywa kwembangela kuhlaka lommese phansi kommese osendaweni okwamanje, uhlaka lommese lulonke ngokucindezela, lungahlehliswa lube esimweni salo sokucindezela, ukulawulwa kwesivinini sokubuyisela uwoyela we-valve, umthelela wendawo yamandla. .
