Taabolo min bɛ ye ka tɛmɛn kosɛbɛ Hydraulic Directional Control Valve dilanni na

1. Dajirali min bɛ wele ko Hydraulic Directional Control Valves

Jiko siratigɛ kɔlɔsili bɔlɔn (a bɛ fɔ a ma kosɛbɛ ko sira caman sɛgɛsɛgɛlilan) ye fɛnba ye jiko siratigɛ bɛɛ la, min ka baara ye ka ji tulu jibɔ sira, a jibɔ hakɛ ani a tansiyɔn kɔlɔsi.
A ka c’a la, a bɛ kɛ ni valve farikolo ye, spool, ressort, sealing rings ani control mechanism .
Ni valve bɛ baara kɛ, hydraulique tulu bɛ se ka tila-tila sɛrɛkili suguya caman cɛ, o bɛ kɛ sababu ye ka actuator caman kɛ — i n’a fɔ hydraulique silinda walima hydraulique moteur — ka baara kɛ ɲɔgɔn fɛ.
Directional control valves bɛ baara kɛ kosɛbɛ sɛnɛ masinw na, jɔli minɛnw na, fɛnw kɔrɔtalanw na , ani jiko fanga suguya caman na , o b’a to u ye dɔ ye . kɔlɔsilifɛn kolomaw bi jiko siratigɛw

Olu cɛma, taabolo min ka gɛlɛn kosɛbɛ — wa tuma caman na, mɔgɔ bɛ ɲinɛ min kɔ kosɛbɛ — o ye kɔrɔbɔli ye.

Kɔrɔbɔli bɛ kɛ kɛrɛnkɛrɛnnenya la:

1. Fɛn minnu bɛ na, olu sɛgɛsɛgɛli

2. Spool fit sɛgɛsɛgɛli

3. Tumu bɔli sɛgɛsɛgɛli laban sani a ka ci

3. Fɛn minnu bɛ na, olu sɛgɛsɛgɛli

Nin ye lafasali sira fɔlɔ ye jogoɲini na.

Sɛgɛsɛgɛli baara kunbabaw ye :

• Casting yecogo: Aw bɛ a lajɛ ni cɛncɛn dingɛw, faraw, pores, inclusions, walima deformation.

• Dimensions correction: Aw bɛ baara kɛ ni calipers, bore gauges ani surface roughness testers ye walasa ka dimensions keys, centres distances ani machines allowances suman.

• Fɛnw dilanni : Aw bɛ nɛgɛ ni kemikali sɛgɛsɛgɛli kɛ k’a sɔrɔ a ma kɛ cogo si la walasa ka a jira ko masinw fanga ni degun kunbɛnni bɛ bɛn dilancogo sariyaw ma.

Fɛnɲɛnɛma minnu bɛ se ka kɛ, olu dɔrɔn de bɛ masin kɛcogo ɲuman sabatilen sabati ani u lajɛcogo ɲuman min bɛ se ka da a kan kɔfɛ.

4. Spool Fit Sɛgɛsɛgɛli

Bɛn min bɛ sumanmugu sɔgɔlan ni sumanmugu farikolo cɛ, o de bɛ baara kɛcogo nɔgɔya ani a datugucogo jira.
Masina baara waati, yɔrɔ fila bɛɛ bɛ ni tolerance deviations ye —ni clearance ka bon kojugu, o bɛ na ni kɔnɔna bɔgɔ ye, ka baara kɛ dɔɔnin dɔɔnin, walima ka degun sabatibali sɔrɔ ; ni a sirilen don kojugu, a bɛ kɛ sababu ye ka nɔrɔ, ka sumaya kojugu, walima ka fɛn caman wuli ka ɲɛ.

Walasa ka tiɲɛni kɛ, fɛɛrɛtigi setigiw bɛ bololabaara kɛ ka spool ni farikolo bɛnkan kɛ :

• Aw bɛ bɔgɔdaga don foroko kɔnɔ ka sɛgɛnlafiɲɛbɔlan jateminɛ ni bolo ye;

• Aw bɛ fila-fila minnu bɛ bɛn ɲɔgɔn ma, olu sɛbɛn ani ka taamasiyɛn kɛ walasa ka lajɛ kelen-kelen bɛɛ lajɛ.

Hali n’o kɛcogo in bɛ waati caman ta, o de ye fɛnba ye min bɛ danfara don valve ɲumanw ni minnu ka dɔgɔn.

5. Tumu bɔli sɛgɛsɛgɛli laban

Nin ye ka jogo sɛgɛsɛgɛli laban ye. valve lajɛlen

Kɔrɔbɔli in kɔnɔ, ninnu dɔw ye ninnu ye:

• Tumu bɔli sɛgɛsɛgɛli : Aw bɛ ji tulu pikiri kɛ ni tansiyɔn hakɛ ye walasa ka a lajɛ ni kɔnɔna ni kɛnɛma bɔgɔ tɛ.

• Baarakɛcogo ni sɛgɛsɛgɛli kɛcogo : Aw bɛ a lajɛ ni spool jɔyɔrɔ kelen-kelen bɛɛ bɛ baara kɛ ka ɲɛ ani ko jaabiw jaabiw sabatilen don.

• Flow ni temperature rise test : Aw bɛ valve sabatili ni funteni bɔli jateminɛ baara kɛtuma na.

Valve bɛɛ min bɛ se, o ka kan ka tɛmɛ banbali sɛgɛsɛgɛli dafalen na , wa hali sɛgɛsɛgɛlikɛla min bɛ se kosɛbɛ, o bɛ se ka unit 100 ɲɔgɔn dɔrɔn sɛgɛsɛgɛ tile kɔnɔ.

6. Kuncɛli

Kuma surun na, nin sɛgɛsɛgɛli fɛɛrɛ saba ninnu — sɛgɛsɛgɛli min bɛ kɛ ni donna ye, sɛgɛsɛgɛli min bɛ kɛ ni spool fit ye, ani tulu bɔli sɛgɛsɛgɛli laban — olu nafa ka bon kosɛbɛ.
Kɛrɛnkɛrɛnnenya la, spool fit ni sɛgɛsɛgɛli labanw bɛ a jira k’a ɲɛsin a ma ni valve dɔ bɛ baara kɛ ka ɲɛ foro kɔnɔ: baara kɛcogo ɲuman, jaabi tigitigi, ani baara kɛcogo min bɛ se ka da a kan.

A fɔ man di nka, bi sugu la, ɲɔgɔndanba bɛ min na, fɛn dilannikɛla dɔw bɛ u sinsin musakaw dɔgɔyali kan sanni ka fɛɛrɛ kuraw ni baarakɛcogo ɲuman yiriwa.
Walasa ka nkɔni tigɛ, bololabaarakɛlaw ka sɔgɔli ni tulu bɔli sɛgɛsɛgɛli dafalen bɛ tɛmɛ tuma dɔw la , o bɛ na ni fɛn dilannenw baaracogo jugu ye.
Jidagayɔrɔ min bɛ se ka da a kan tiɲɛ na, o bɛ bololabaara gɛlɛnw ni kɔrɔbɔli kololi de wajibiya , a tɛ kɛ sira surunw ye.

Jiko baara ka gɛlɛn ani a bɛ fɛn caman ɲini—a dilannikɛlaw ka kan ka tugu jogoɲumanya ni kokuradonni kɔ waatijan kɔnɔ , wa baarakɛlaw ka kan ka tɛmɛn yecogo kan walasa ka baara kɛcogo banbali ni lakana sabati.
