Kabaliksan na Produkto

Saray Manunan Tampok na Istruktura

1. Doble ya Eksentrikon Desinyo
   • Inmunan Eksentrisidad: Saybalbulasay shaft et akaarawi ed sentro na disc, ya mamapaabeba na friction legan ya manlulukas/mansara tan mamapaabeba ed pakasulong ed saray sealing surfaces.
   • Komaduan Eccentricity: Say shaft et lalon arawi ed sentro na pipeline, ya manggagawa na “wedging effect” ya mamaaligwas ed performance na sealing legan ya onsara so disc.
   • Benepisyo: Mangiiter na superyor ya panag-seal tan mamalaknab na serbisyo no ikompara ed saray single-eccentric o concentric ya desinyo.
2. Soft Seal Mechanism
   • Say balbula et manguusar na soft sealing ring (kaslakan ya gawad EPDM, NBR, o PTFE) ya akaamot ed laman o disc na balbula, ya mangiseguro na ag-onlooban na dagem tan makapipara ed nanduruman media (alimbawa, danum, larak, gas, tan ag-abrasive ya pluido).
   • Bentaha: Abeba so leakage rate (ontutumbok ed API 598 o ISO 15848 ya estandarte) tan daiset so torque ya nakaukolan parad operasyon.
3. Dry Shaft Construction
   • Say baras et akasara ya nisian ed agos na media, ya ag direktan makapitongtong ed pluido. Sayan desinyo et mamaandi na posiblin dalan na panag-leak ed shaft tan mamapaabeba ed peligro na corrosion, lalo la ed saray agresibo ya kaliberliber.
   • Manunan Kabiangan: Saray de-kalidad ya stem seals (alimbawa, V-type packing odino mechanical seals) et mamaseguro ya anggapoy leakage ed shaft.
4. Koneksion na Flange
   • Ginawa ya walaan na estandarten flange interfaces (alimbawa, ANSI, DIN, JIS) pian mainomay ya i-install ed saray pipeline. Say desinyo na flanged et mangiiter na inkapekder na istruktura tan mamapasimpli ed panmintina.

Prinsipyo na Pankimey

• Panlukas: Legan ya onkukurang so shaft, saydoble-eksentrikosay disc et onalis manlapud akasara ya posisyon, ya kalkalnan onarawi ed anlemew ya selyo. Saray eccentric offsets et mamapaabeba ed inmunan contact stress, ya mamapawala na maabig tan abeban torque ya operasyon.
• Pansara: Say disc et onpawil, tan say double-eccentric geometry et manggawa na progresibon sealing action. Say wedging effect et mamaaligwas ed contact pressure ed baetan na disc tan seal, pian naseguro so malet ya shut-off.
• Tandaan: Say desinyo na dry shaft et mamaseguro ya say shaft et ag naapektoan na temperatura, presyon, odino inka-corrosive na media, ya mamaaligwas ed inkalapagan ya inkapanmatalkan.

Teknikal iran Detalyado

• Panlinis na Danum: Say danum ya inumen, basura, tan saray sistema na imburnal (kaukolan so atagey a seal parad estandarte na kalinisan).
• Industriya na Kemikal: Makaderal iran pluido, asido, tan alkali (say amagan baras et manproprotekta ed panangataki na kemikal).
• HVAC Systems: Air conditioning tan heating pipelines (abeban torque parad mabetbet ya operasyon).
• Petrochemical & Oil/Gas: Aliwan-abrasive ya media a singa say larak, gas, tan solvents (napanmatalkan ya pansara ed saray kritikal a proseso).
• Kakanen tan Iinumen: Sanitary applications (Saray selyo ya ontutumbok ed FDA et mamaseguro na kaligenan na produkto).

• Bentaha ed saray tradisyonal a balbula

  • Superior Sealing: Saray soft seals et mamaandi na leakage, matukoy parad saray aplikasyon ya mankaukolan na proteksion ed kaliberliber odino atagey a kalinisan.
  • Energy Efficiency: Say abeban torque ya operasyon et mamapaabeba ed pankaukolan na actuation power, ya mamapaabeba ed gastos ed operasyon.
  • Say andukey a bilay: Say doble-eksentrikon desinyo et mamalemew ed pakasulong, bangta say dry shaft et manproprotekta sumpad panag-apag, ya mamaparukey na serbisyo.
  • Makatipid na Espasyo: Kompakton istruktura no ikompara ed saray balbula na gate o globe, ya marakep parad limitadon espasyo.

  Saray Tip ed Panmintina tan Pangipuesto

  • Instalasyon: Seguroen ya aka-align iray flanges tan parepareho so inka-tighten na saray bolts pian napaliisan so stress ed laman na balbula.
  • Panmintina: Regular ya nengnengen no kasin aderal so soft seal tan salatan no aderal. Panapanaon ya i-lubricate so shaft tan actuator pian naseguro ya maabig so operasyon to.
  • Panangiyan: Isimpen ed amagan pasen ya anggapoy dabok ya medyo lukas so balbula pian naekal so stress ed selyo.
  Sayan balbula et mankokombina na maaligwas ya inhinyeriya tan praktikal a desinyo, ya mangiyoopresi na napanmatalkan tan epektibo ed gastos a solusyon parad modernon pankaukolan ed panangontrol na agos na industriya. Parad espisipikon panagpasadya (alimbawa, pananguman na materyales odino espisyal iran panag-coat), mitongtong ed manggagawa.
