Silindri minnu bɛ kɛ ni fiɲɛ ye siɲɛ fila, olu bɛ u jigi da sigilan suguya caman kan walasa ka baara kɛ ka ɲɛ, ka fiɲɛ bɔli bali, ani ka baara kɛcogo ɲuman sabati waati kɔnɔ. Silindri minnu bɛ kɛ siɲɛ fila, olu ka teli ka kɛ sigilan minnu na, olu ye:
## 1. **Piston Seals**
- **Purpose**: Nin sigilanw bɛ sɔrɔ piston lamini na, ka sigilan sirilen siri piston ni silinda bara cɛ walasa fiɲɛ kana bɔn ni piston bɛ taa.
- **Suguyaw**:
- **O-rings**: Piston sigilan suguya min ka ca, a ka ca a la a bɛ kɛ ni lastikuw ye walima elastomɛri i n’a fɔ nitrile, viton, walima poliyuritani. O-ringw bɛ sigilan dafalen di ni barikalan ye min tɛ se ka degun.
- **u-cup seals**: U-cups (walima fila-fila sigilanw) cogoya bɛ i n'a fɔ "U" ani ka taamasiyɛn sɛgɛsɛgɛlen, sirilen di piston lamini na. U bɛ se ka fiɲɛ bɔli bali degun na, wa u bɛ kɛ ka caya degunba la.
- **Wiper Seals**: A ka ca a la, a bɛ kɛ ni piston sigilanw ye, o sigilanw bɛ nɔgɔ ni nɔgɔ bɔ bere la, ka nɔgɔ bali ka don silinda la.
### 2. **Rod sigilanw**
- **Purpose**: Bere sigilanw bɛ fiɲɛ walima tulu bali ka bɔ piston bere la, ka degun mara silinda kɔnɔ ani ka baara kɛ ka ɲɛ.
- **Suguyaw**:
- **O-rings**: Simple and efficace, O-ring rod seals ka teli ka kɛ pneumatic baara caman na.
- **V-ring seals**: sigilan V-cogo min dilannen don walasa ka sigilan sirilen di bere ma, tuma caman na, a bɛ kɛ ni kɔpi bololanɛgɛw ye walasa ka sigilan baarakɛcogo ɲɛ.
- **polyurethane seals**: Nin sigilanw bɛ mɛn ani u bɛ sɛgɛnba di, o b’a to u bɛnnen don teliya la.
- **Wiper Seals**: A bɛ fɔ fana ko "scraper" sigilanw, ninnu bɛ kɛ ka nɔgɔ walima nɔgɔ suguya o suguya bɔ piston bere la n'a bɛ don ani ka bɔ silinda kɔnɔ. U bɛ dɛmɛ don ka bere ni kɔnɔnafɛn wɛrɛw tanga sɛgɛn ma.
### 3. **End Cap Seals**
- **Purpose**: Nin sigilanw bɛ kɛ silinda dakun dakunw na walasa fiɲɛ kana bɔ ani ka kɔnɔna tansiyɔn to silinda kɔnɔ.
- **Suguyaw**:
- **O-rings**: O-ringw bɛ kɛ ka caya walasa ka ɲɔgɔndanw datugu dakun dakunw ni silinda tuubu cɛ. U ka nɔgɔn ani u musaka ka dɔgɔ.
- **Flat Seals**: A ka c'a la, ninnu bɛ dilan ni fɛnw ye i n'a fɔ lastikuw walima nɛgɛ ani u dilannen don walasa u ka se ka u ko u laban dakunw na walasa ka sigilan siri.
### 4. **Backup Rings**
- **Purpose**: Backup rings bɛ kɛ ka fara sigilan fɔlɔw kan (i n’a fɔ O-rings) walasa u kana bɔ kɛnɛ kan walima ka tiɲɛ ni degunba ye. O bololanɛgɛw bɛ dɛmɛ wɛrɛw di ani ka sigilan ɲɛnamaya janya.
- **Materials**: A ka c'a la, backup rings bɛ dilan ni fɛn gɛlɛnw ye i n'a fɔ PTFE (Teflon) walima Thermoplastiques walasa ka tansiyɔnba muɲu ani ka se ka sigilan fanga wɛrɛ di.
### 5. **Buffer Seals**
- **Purpose**: Tampon sigilanw bɛ dɛmɛ ka sɔgɔsɔgɔninjɛ minɛ ani ka tansiyɔnba wulilanw bali ka sigilanw tiɲɛ, kɛrɛnkɛrɛnnenya la, baara minnu bɛ kɛ ni degun caman yeli ye walima ni barika ye.
- **Materials**: Olu bɛ kɛ ni fɛn nɔgɔlenw ye i n’a fɔ lastikuw walima poliyuritan walasa ka cushioning sɔrɔ.
## # 6. **Rod Scrapers**
- **Purpose**: Nin sigilanw, minnu bɛ wele fana ko berew, olu bɛ bila silinda da la walasa ka nɔgɔw, nɔgɔ, walima ji bɔ bere la ni a bɛ janya ani ka segin kɔ. O bɛ dɛmɛ ka sigilan wɛrɛw ka dafalenya sabati.
- **Materials**: A ka c’a la, a bɛ dilan ni lastikuw, poliyuritan, walima fɛn kɛrɛnkɛrɛnnenw ye minnu bɛ kɛ ɲɔgɔn fɛ.
## 7.
- **Purpose**: Kusi sigilanw bɛ kɛ silinda la walasa ka dɔ bɔ a sɔgɔli ni a mankan na sɔgɔsɔgɔninjɛ laban na ni a bɛ piston sumaya ni a bɛ ka surunya silinda laban na. O sigilanw nafa ka bon kɛrɛnkɛrɛnnenya la baarakɛcogo la minnu teliya ka bon.
- **Suguyaw**: Ninnu bɛ se ka don dakunw na ani u bɛ dilan ni fɛn nɔgɔlenw ye i n’a fɔ ɛlasɔmu walima plastiki.
### Fɛn minnu bɛ kɛ ka fiɲɛ bila silinda sigilanw na:
- **Nitrile (NBR)**: A bɛ kɛ ka caya sigilanw na ka da a kan a bɛ se ka tulu, sɛnɛfɛnw, ani fɛn bɛɛ sɛgɛn.
- **Viton (FKM)**: A bɛ dɔn a ka funteni hakɛ caman na ani a ka kemikaliya sabatili la, a ka teli ka kɛ baara caman na.
- **Polyurethane (PU)**: A bɛ sɔgɔli kɛcogo ɲuman di ani a bɛ kɛ bere ni piston sigilan fila bɛɛ la.
- **EPDM**: A ka ca a la, a bɛ kɛ sigilanw ye sigidaw la minnu bɛ funteni jugumanba ni ozɔni kɛlɛ.
- **PTFE (Teflon)**: A bɛ kɛ kɔpi bololanɛgɛw la ani tuma dɔw la piston sigilanw na ka da a sɔgɔli dɔgɔyali kan ani a ka se ka kemikaliw kɛlɛ kosɛbɛ.
- **SiliCone**: A bɛ kɛ baara dɔw la funteni caman kɛlɛli kama, hali ni a man ca pneumatic silindaw la.
### Farankan
Silindri minnu bɛ kɛ ni fiɲɛ ye, olu bɛ se ka kɛ siɲɛ fila ye, o bɛ bɔ fɛnw na i n’a fɔ tansiyɔn, funteni, teliya, ani fɛn suguya min bɛ kɛ ni fiɲɛ ye (fiɲɛ, tulu walima ji) silinda bɛ sɔrɔ min na. Ni aw bɛ baara kɛ ni piston sigilanw, bere sigilanw, ani kɔkanna bololanɛgɛw faralen ye ɲɔgɔn kan cogo bɛnnen na, fiɲɛbɔlanw bɛ se ka baara kɛ ka ɲɛ, ni u bɔli ka dɔgɔn, baarakɛwaati jan, ani ladonni dɔgɔyali.
