- Рекомендации по выбору & Альтернативные решения
5.1 Три ключевых фактора выбора
Согласование нагрузки: Thrust ≥ Load × 1.5 safety factor; 40 mm bore provides 754 N thrust @ 6 бар, suitable for load ≤ 500 Н.
Stroke confirmation: Reserve ≥10 mm cushioning space for 50 mm stroke to avoid rigid impact.
Environmental adaptation:
Еда / pharmaceutical industry: Must adopt CRDSNU (полностью нержавеющая сталь + NSF‑H1 lubrication).
Высокая температура (>80°С): Equip with S6 high-temperature seal kit.
Chemical corrosion environment: Adopt FKM seals + CRC3 stainless steel.
5.2 Рекомендуемые альтернативные решения
| Сценарий применения | Рекомендуемое решение | Преимущества |
| Standard food-grade environment | ЦРДСНУ-40-50-ППВ-А | Полностью нержавеющая сталь + adjustable cushioning, suitable for dynamic loads |
| Static load working condition | CRDSNU-40-50-PPS-A | Self-adjusting cushioning, не требующий обслуживания, более низкая стоимость |
| Ultra-high temperature (>120°С) | Custom high-temperature cylinder | Special seals and materials for extreme temperature conditions |
| Budget-limited project | Domestic stainless steel cylinder (например. Airtac SI series) | Высокая стоимость исполнения, meets basic functional requirements |
| Clean room environment | ЦРДСНУ-40-50-ППВ-А + A1 wiper ring | Enhanced chemical resistance, meets clean room standards |
5.3 Установка & Рекомендации по техническому обслуживанию
- Clean cylinder ports before installation to prevent impurities from entering and shortening seal service life.
- Cushioning adjustment: Start with minimum cushioning, then gradually increase to proper effect; avoid over-cushioning causing cylinder creeping.
- Pipe length ≤ 5 м, inner diameter ≥ 6 mm to ensure stable air supply.
- Regular inspection every 6 месяцы: Check seal condition, piston rod surface and cushioning performance; replace parts in time if abnormal.
- Rinse with clean water after use in food processing environments to keep the cylinder clean.
