Phốt chắn bụi tại Duy Lập Đồng Nai

[CH Duy Lập]

Phốt chặn bụi là loại phốt lắp ở đầu cần (rod) của xi lanh thủy lực hoặc khí nén, có nhiệm vụ ngăn bụi bẩn, bùn đất, nước và tạp chất bên ngoài xâm nhập vào trong xi lanh khi cần chuyển động. Đây là lớp bảo vệ đầu tiên, giúp kéo dài tuổi thọ phốt dầu và bề mặt cần.

Chức năng chính

• Ngăn bụi, cát, bùn, nước bám theo cần xi lanh đi vào trong.
• Bảo vệ phốt làm kín chính (oil seal).
• Giảm trầy xước cần xi lanh, hạn chế rò rỉ dầu về lâu dài.
• Tăng độ bền và độ ổn định của hệ thống thủy lực.

Phân loại phổ biến

1. Phốt chặn bụi 1 môi
   • Cấu tạo đơn giản, dùng cho môi trường ít bụi.
2. Phốt chặn bụi 2 môi (có gờ phụ)
   • Hiệu quả cao hơn, dùng cho môi trường nhiều bụi bẩn.
3. Phốt chặn bụi có lõi thép
   • Độ cứng vững cao, giữ hình dạng tốt khi lắp ép.
4. Phốt chặn bụi không lõi thép
   • Linh hoạt, dễ lắp, thường dùng cho kích thước nhỏ.

Vật liệu thông dụng

• PU (Polyurethane): bền mài mòn, dùng phổ biến nhất.
• NBR (cao su nitrile): giá thành tốt, dùng trong môi trường tiêu chuẩn.
• TPU / cao su tổng hợp: cho điều kiện đặc biệt.

Ứng dụng

• Xi lanh thủy lực máy công trình (xe xúc, xe đào).
• Máy ép thủy lực, máy cơ khí, máy sản xuất.
• Thiết bị ngoài trời, môi trường bụi bẩn, ẩm ướt.

Lưu ý khi chọn phốt chặn bụi

• Đúng đường kính cần (Rod) và kích thước rãnh lắp.
• Phù hợp môi trường làm việc (bụi nhiều, bùn, nước).
• Chọn vật liệu tương thích với nhiệt độ và điều kiện vận hành.
  
  Nếu quý khách cần tư vấn chọn phốt chặn bụi đúng kích thước cho xi lanh, hoặc cung cấp phốt chặn bụi PU/NBR chất lượng cao, vui lòng liên hệ với chúng tôi để được hỗ trợ kỹ thuật chi tiết.
