유압 피팅이란 무엇입니까?

Hydraulic fittings are components used in hydraulic systems to connect, route, and control the flow of hydraulic fluid. They are designed to create secure, leak-free connections between various hydraulic components, such as hoses, tubes, pipes, valves, and hydraulic cylinders.

Here are some key aspects of hydraulic fittings:

1. Types: Hydraulic fittings come in various types, each serving specific purposes and connection methods. Some common types include:
   • Hydraulic Hose Fittings: These fittings connect hydraulic hoses to other components. They can have threaded connections, flared ends, or quick-connect couplings.
   • Hydraulic Tube Fittings: These fittings connect hydraulic tubes or pipes. They often involve flared or compression connections and are used when a more rigid connection is required.
   • Hydraulic Adapters allow for compatibility between different types, sizes, or thread patterns of hydraulic components. They facilitate connections between mismatched parts.
2. Connection Methods: Hydraulic fittings use different connection methods to ensure a secure fit. These methods include threaded connections, flared connections, compression fittings, quick-connect couplings, and O-ring face seal fittings. The selection of the appropriate connection method depends on factors such as pressure, flow rate, and system requirements.
3. Materials: Hydraulic fittings are typically made from materials that offer strength, durability, and resistance to corrosion. Common materials include steel, stainless steel, brass, and aluminum. The choice of material depends on factors such as the application's operating conditions, compatibility with the hydraulic fluid, and environmental considerations.
4. Pressure Ratings: Hydraulic fittings are rated for specific pressure ranges to ensure safe operation. The pressure rating indicates the maximum pressure the fitting can withstand without failure. It is important to select fittings with appropriate pressure ratings that match the requirements of the hydraulic system.
5. Sealing Mechanisms: To achieve leak-free connections, hydraulic fittings incorporate sealing mechanisms such as O-rings or sealing washers. These seals prevent hydraulic fluid from escaping and maintain system integrity.
6. Installation and Maintenance: Proper installation and maintenance of hydraulic fittings are crucial for their performance and longevity. It involves ensuring correct tightening torque, inspecting fittings for damage or wear, and replacing seals. Regular maintenance helps prevent leaks, maintain system efficiency, and prolong the life of the fittings.

설치 지침

ROKE 유압 피팅의 너트는 모두 은도금 처리되었으며, 당사 특허 기술로 나노 윤활층을 분사합니다. 이를 통해 설치 토크를 적정 범위 내에서 제어할 수 있습니다.

특히 공간이 좁거나, 작업이 중단된 경우에도 설치가 매우 쉽습니다.

올바른 조립을 위해 조립 지침을 따라야 합니다. 부적절하게 조립하면 고장이나 안전 문제가 발생할 수 있습니다.

피팅 바디에 조립

1. 튜브 절단: 튜브 축에 대해 1/2˚ 각도 허용 오차는 허용됩니다. 튜브 커터는 권장하지 않습니다.

2. 튜브의 안쪽과 바깥쪽 절단면의 부스러기와 이물질을 가볍게 제거하세요. 최대 0.2mm × 45˚의 경사각이 허용됩니다.

3. 튜브 벤딩의 경우, 직선 파이프 끝에서 굽힘 반경까지의 최소 높이는 너트 높이의 두 배 이상이어야 합니다.

4. 피팅 본체의 나사산과 원뿔, 링, 너트의 나사산에 윤활유를 바릅니다.

집회

5. 너트를 끼운 후 튜브 끝에 링을 끼웁니다. 링이 제대로 끼워졌는지 확인하세요.
6. 너트를 피팅 본체에 손으로 돌려 단단히 조입니다. 튜브를 피팅 본체 원뿔의 어깨 부분에 대고 고정합니다.

7. 너트와 튜브에 표시를 하여 너트의 규정된 회전수를 측정합니다.
8. 너트를 1 1/4바퀴 조이세요. 튜브가 튜브와 함께 돌아가서는 안 됩니다. 링의 끝부분을 막으면 조임 토크를 높여 과도한 조임을 방지할 수 있습니다.

점검 및 최종 조립

9. 너트를 풀고 링이 장착된 튜브를 피팅에서 분리하세요. 첫 번째 절삭날 전에 파이프에 눈에 띄는 칼라가 형성되었는지 확인하세요. 그렇지 않으면 조금 더 조이세요.

10. 미리 조립된 튜브를 피팅에 삽입합니다. 렌치로 피팅 본체를 잡고, 뚜렷하게 느껴지는 저항 지점을 지나 약 1/4바퀴 정도 더 돌려 너트를 조입니다.
