Baara siratigɛ la, jiko ɲɔgɔndanw ka kan ka sariya jɔnjɔn saba dafa waati kelen na: fɔlɔ, ka ji sira basigilen sigi senkan walasa ka tulu bɔli bali min tɛ bali; filanan, aw bɛ sistɛmu baara tansiyɔn muɲu (a ka c’a la 10-50 MPa, nka a bɛ tɛmɛ 100 MPa kan cogo jugu la) ni plastiki caman b’a la walima ka a tiɲɛ; ani sabanan, aw bɛ sigida tansiyɔn sabatilen mara ni kɔnɔna ni kɛnɛma bɔgɔbɔ siraw datuguli ye sigilan yɔrɔ la.
2. Siginiden: balansi barikama min bɛ boli ni degun ye .
Hydraulique fittings (ji-minɛnw) sigili baara ye u ka baara kɔnɔko jɔnjɔn ye. A ka sariyasen sinsinnen bɛ "dege self-Tightening" ani "pre{2}}compression compensation" fɛɛrɛ fila kan. Ni jibolisiraw bɛ baara la, ji bɛ tansiyɔn fɔlɔ sɔrɔ pɔnpe ka wale kɔrɔ. Nin yɔrɔ in na, fanga min bɛ siginiden yɔrɔ kan, o bɛ bonya ni degun bɛ ka bonya. Misali la, O-ring bɛ degun radiyali la, wa a ka ɲɔgɔn sɔrɔli yɔrɔ ni a ɲɔgɔnna degun bɛ bonya waati kelen na, ka yɔrɔ fitininw fa farikoloba ni ɲɔgɔndan cɛ (i n’a fɔ dingɛ minnu bɛ sɔrɔ dugukolo sanfɛla gɛlɛya fɛ). Ka ɲɛsin sigilanw ma (i n’a fɔ 74 degere taper angle of hydraulique pipe fittings), High{9}}Tressure tulu bɛ baara kɛ kɔfɛ ka kɛɲɛ ni tapered surface ye, ka sigilanw gɛrɛ ɲɔgɔn na ka gɛrɛ ɲɔgɔn na, ka jaabi ɲuman di: "Ni degun ka bon, seal bɛ gɛlɛya ka taa a fɛ.
A ka kan ka kɔlɔsi ko sigili tɛ tali kɛ fɛnw sɛgɛsɛgɛli dɔrɔn de la. Pre-compression design ye ko kɔrɔba ye. Misali la, O-Rings bɛ 15%-30% sɛgɛsɛgɛli hakɛ de wajibiya a sigili waati (nafa kɛrɛnkɛrɛnnen bɛ bɔ lastikuw gɛlɛya ni a baara funteni na) walasa ka sigili fɔlɔ sɔrɔ hali ni degun dɔgɔmanw bɛ.

3. Baarakɛcogo sabatili baarakɛcogo la min bɛ kɛ ni fanga ye .
Baara yɛrɛ la, jibolisiraw ka kan ka degun jiginniw muɲu tuma caman (i n’a fɔ waati tɛmɛnen- tansiyɔn jiginni minnu bɛ sɔrɔ jibolisiraw sɔgɔli fɛ), funteni caman yeli (o bɛ baara kɛ funteni hakɛ la min bɛ -40 degɛrɛ la fo ka se +120 degere ), ani masinw yɛrɛyɛrɛli ma (i n’a fɔ jɔli masinw yɛrɛyɛrɛli tuma bɛɛ). Walasa ka nin gɛlɛyaw ɲɛnabɔ, a baarakɛcogo bɛ sabatili sɔrɔ nin fɛɛrɛ ninnu fɛ:
A fɔlɔ, degun{0}}Baarakɛcogo dilancogo: sanfɛ-dafalenw ka teli ka damping structures (i n’a fɔ throttle grooves walima tampon chambres). Ni jibolisira dɔ sɔrɔla sistɛmu kɔnɔ, damping structure bɛ tansiyɔn wuli waati janya ani ka sigilan tiɲɛni bali ka da a kan a ka ca kojugu. Misali la, high-pressure hose connectors dɔw bɛ ni kɔnɔna spiral flow siraw ye minnu bɛ tulu bɔli sira janya walasa ka shock fanga dɔgɔya.
Filanan, funteni bonya musaka : funteni caman cili bɛ se ka kɛ sababu ye ka danfara don siginidenw ni nɛgɛ yɔrɔw ka funteni bonya ni u jiginni hakɛ la (misali la, lastikuw bɛ se ka bonya ni hakɛ ye min ka ca ni nɛgɛ ye siɲɛ 10 funteni na), o bɛ se ka kɛ sababu ye ka sigilan fɔlɔ tiɲɛ.

A laban na, yɛrɛyɛrɛ balili: Anti-Loosening design of the locking mechanism ye fɛnba ye. Misali la, joli-sira-funu minnu bɛ siri, olu ka teli ka fara ɲɔgɔn kan ni resɔn kolanw ye walima nilon locknuts, minnu bɛ kɛ ni frictionnel resistance ye walasa ka lajɔli bali min bɛ sɔrɔ yɛrɛyɛrɛ fɛ.
