Ukupakisha Seal Maintenance Indlela

1. Hlanza ibhokisi lokupakisha lephampu yekesi ehlukanisiwe, futhi uhlole ukuthi akukho yini imihuzuko nama-burrs ebusweni be-shaft. Ibhokisi lokupakisha kufanele lihlanzwe futhi indawo ye-shaft kufanele ibe bushelelezi.

2. Hlola ukuphela kwe-shaft. Ukungalingani kokuphuma kwe-rotor kufanele kube phakathi kwebanga elivumelekile, ukuze ugweme ukudlidliza ngokweqile futhi kube okuphambene nokupakisha.

3. Faka i-sealant noma i-lubricant efanelekile phakathi nendawo ebhokisini lokupakisha nangaphezulu kwe-shaft.

4. Ukuze uthole ukupakishwa okupakishwe kuma-roll, thatha induku yokhuni enobukhulu obufana nejenali, uvunguze ukupakisha kuyo, bese uyisika ngommese. Unqenqema lommese kufanele lube ngu-45 °.

5. Izigcwalisi kufanele zigcwaliswe ngamunye ngamunye, hhayi amaningana ngesikhathi. Indlela iwukuba uthathe ucezu lokupakisha, ugcobe okokugcoba, ubambe umkhawulo owodwa wesixhumi esibonakalayo sokupakisha ngezandla zombili, usikhiphe ngasohlangothini lwe-axial, ulwenze luthandelene, bese ulufaka kujenali ngokusebenzisa i-incision. Ungahlukanisi ngakundlela ye-radial ukuze ugweme isixhumi esibonakalayo esingalingani.

6. Thatha umkhono we-shaft wensimbi wosayizi ofanayo noma ubulukhuni obuphansi kune-shaft yebhokisi lokupakisha, phushela ukupakisha engxenyeni ejulile yebhokisi, futhi ufake ingcindezi ethile kumkhono we-shaft onendlala ukuze wenze ukupakisha kufinyelele. ukucindezela kwangaphambili. Ukuncipha kokulayisha kuqala kungu-5% ~ 10%, kanti ubuningi bungama-20%. Vula i-shaft komunye umbuthano bese ukhipha umkhono we-shaft.

7. Ngendlela efanayo, layisha okwesibili nokwesithathu. Qaphela: lapho inombolo yokugcwalisa ingu-4-8, i-interface kufanele inyakaze ngamadigri angama-90; ama-filler amabili kufanele aphazamiseke ngama-degree angu-180; Izingcezu ezi-3-6 kufanele zinyakaze ngamadigri angu-120 ukuvimbela ukuvuza ngokusebenzisa isikhombimsebenzisi.

8. Ngemuva kokuthi ukupakishwa kokugcina kugcwaliswe, i-gland kufanele isetshenziselwe ukuhlanganisa, kodwa amandla okucindezela akufanele abe mkhulu kakhulu. Ngesikhathi esifanayo, zungezisa i-shaft ngesandla ukwenza amandla okucindezela omhlangano athambekele ekusabalaleni kwe-parabola. Bese ukhulula ikhava kancane.

9. Yenza ukuhlolwa kokusebenza. Uma ingakwazi ukuvalwa, cindezela ukupakisha okuthile; uma ukushisa kukhulu kakhulu, kukhulule. Ingasetshenziswa kuphela uma izinga lokushisa lokupakisha liphakeme ngo-30-40 ℃ kunelemvelo.Izidingo zobuchwepheshe ze-split case pump packing seal, ukufakwa kwezigxivizo zokupakisha, kufanele kuhambisane nezinhlinzeko zemibhalo yobuchwepheshe.
