Nneɛma Titiriw a Ɛwɔ Nhyehyɛe Mu

1. Nsusuwii a Ɛyɛ Eccentric Mmienu
   • Eccentricity a Edi Kan: Thevalveshaft no yɛ offset fi diski no mfinimfini, ɛtew friction bere a wobue/to mu na ɛtew ɔsɛe wɔ sealing surfaces no so.
   • Eccentricity a Ɛto so Abien: Wɔde shaft no fi pipeline no mfinimfini bio, na ɛma “wedging effect” a ɛma sealing adwumayɛ yɛ kɛse bere a disc no to mu no.
   • Mfaso: Ɛma ahotoso a ɛkorɔn wɔ nsɔano so na ɛtrɛw ɔsom nkwa nna mu bere a wɔde toto nsusuwii a ɛyɛ soronko anaasɛ nea ɛwɔ mfinimfini ho no.
2. Adwinnade a Wɔde Nsɔ Nsɔano a Ɛyɛ Dwo
   • Valve no de nkatabo a ɛyɛ mmerɛw (a wɔtaa de EPDM, NBR, anaa PTFE na ɛyɛ) a wɔde ahyɛ valve nipadua anaa diski no mu di dwuma, na ɛhwɛ hu sɛ mframa ntumi nkɔ mu na ɛne nsɛm ho amanneɛbɔ ahorow (sɛ nhwɛso no, nsu, ngo, mframa, ne nsu a ɛnyɛ abrasive) hyia.
   • Mfaso: Leakage rates a ɛba fam (edu API 598 anaa ISO 15848 gyinapɛn ahorow) ne torque kakraa bi a ɛho hia ma adwumayɛ.
3. Dry Shaft Adansi a Wɔyɛ
   • Wɔatoto agyan no mu wɔ ɔkwan soronko so wɔ nsɛm ho amanneɛbɔfo a ɛsen no ho, na ɛmma nsu no ntumi nkɔ tẽẽ. Saa nhyehyɛe yi yi akwan a ebetumi ama nsu atumi afa shaft no mu no fi hɔ na ɛtew asiane a ɛwɔ hɔ sɛ ɛbɛsɛe no so, titiriw wɔ mmeae a basabasayɛ wɔ.
   • Key Component: Stem seals a ɛyɛ papa (sɛ nhwɛso no, V-type packing anaa mechanical seals) hwɛ hu sɛ zero leakage wɔ shaft no ho.
4. Flange Nkitahodi
   • Wɔayɛ no ne standard flange interfaces (sɛ nhwɛso no, ANSI, DIN, JIS) ma ɛnyɛ den sɛ wɔde besisi nsuo afiri mu. Flanged design no ma ɔdan no gyina pintinn na ɛma nsiesie yɛ mmerɛw.

Adwumayɛ Nnyinasosɛm

• Bue: Bere a shaft no di akɔneaba no,...nea ɛyɛ nwonwa mmɔho abiendisc no fi baabi a wɔato mu no, na ɛde nkakrankakra fi nsɔano a ɛyɛ mmerɛw no ho. Eccentric offsets no brɛ mfiase contact stress ase, na ɛma wotumi yɛ adwuma yiye na torque a ɛba fam.
• Ntotoe: Disk no dannan n’akyi, na geometry a ɛyɛ abien-eccentric no ma nsɔano adeyɛ a ɛkɔ so nkakrankakra ba. Wedging effect no ma contact pressure a ɛda disc ne seal no ntam no yɛ kɛse, na ɛma wotumi to mu denneennen.
• Hyɛ no nsow: Dry shaft nhyehyɛe no hwɛ hu sɛ shaft no kɔ so yɛ nea nsɛm ho amanneɛbɔfo hyew, nhyɛso, anaasɛ nea ɛporɔw no nnya so nkɛntɛnso, na ɛma ahotoso nyinaa yɛ kɛse.

Mfiridwuma Ho Nsɛm a Wɔakyerɛkyerɛ Mu

• Nsuo a Wɔde Yɛ Adwuma: Nsuo a wɔnom, nsuo fĩ, ne nsuo fĩ (ɛhwehwɛ sɛ wɔde nsɔano kɛseɛ hyɛ mu ma ahoteɛ gyinapɛn ahodoɔ).
• Nnuruyɛ Nnwuma: Nsu a ɛporɔw, acid, ne alkali (aduru a ɛyɛ dry bɔ ho ban fi nnuru ntua ho).
• HVAC Systems: Mframa a wɔde yɛ adwuma ne ɔhyew afiri (torque a ɛba fam ma ɛyɛ adwuma mpɛn pii).
• Petrochemical & Oil/Gas: Nneɛma a ɛnyɛ abrasive te sɛ ngo, gas, ne solvents (a wotumi de ho to so wɔ nneɛma a ɛho hia mu).
• Aduan & Nsã: Nneɛma a wɔde di dwuma wɔ ahotew mu (nsɔano a ɛne FDA hyia no hwɛ hu sɛ nneɛma no yɛ nea ahobammɔ wom).

• Mfaso a Ɛwɔ So Sen Amammerɛ Valve

  • Nsɔano a Ɛkorɔn: Nsɔano a ɛyɛ mmerɛw yi nsu a ɛtwetwe fi hɔ, ɛfata ma nneɛma a ɛhwehwɛ sɛ wɔbɔ nneɛma a atwa yɛn ho ahyia ho ban anaasɛ ɛho tew kɛse.
  • Ahoɔden a Wɔde Di Dwuma: Torque a ɛba fam adwumayɛ ma actuation ahoɔden a wɔhwehwɛ no so tew, na ɛtew adwumayɛ ho ka so.
  • Nkwa tenten: Nsusuwii a ɛyɛ nwonwa mmɔho abien no ma ɔsɛe pii, bere a dua a ɛyɛ dry no bɔ ho ban fi nsɛe ho, na ɛma nkwa nna kyɛ.
  • Ahunmu a Wɔkora So: Sɛ wɔde nhyehyɛe a ɛyɛ ketewaa toto apon anaa globe valve ho a, eye ma mmeae a wɔde nneɛma a ɛwɔ ahunmu kakraa bi si hɔ.

  Maintenance & Installation Afotusɛm

  • Fa si hɔ: Hwɛ sɛ flanges no ahyia na wɔakyekye bolts no mu den pɛpɛɛpɛ na wɔakwati nhyɛso wɔ valve nipadua no so.
  • Nsiesie: Hwɛ nsɔano a ɛyɛ mmerɛw no mu daa sɛ asɛe anaa na sɛ asɛe a, sesa. Fa srade gu shaft ne actuator no so bere ne bere mu na ama woahwɛ ahu sɛ ɛyɛ adwuma yiye.
  • Fa sie: Fa sie baabi a ɛhɔ yɛ kusuu a mfutuma nni mu a valve no abue kakra na ama nhyɛso a ɛwɔ nsɔano no so no afi hɔ.
  Saa valve yi ka mfiridwuma a ɛkɔ anim ne nhyehyɛe a mfaso wɔ so bom, na ɛde ano aduru a wotumi de ho to so na ɛho ka sua ma nnɛyi mfiridwuma mu nsu a ɛsen so hwɛ ahiade ahorow. Sɛ wopɛ sɛ woyɛ nsakrae pɔtee bi (sɛ nhwɛso no, nneɛma a wɔayɛ no foforo anaasɛ nea wɔde kata so titiriw) a, yɛsrɛ wo, kɔ nea ɔyɛe no nkyɛn.
