2.2 피스톤 씰 구조

피스톤 씰 압력 테스트 포인트 어댑터는 주로 피스톤, O- 링 및 스프링으로 구성됩니다. 씰링 링은 피스톤 홈에 있습니다.

스프링 사전 압축 추력을 통해 씰링 콘 (방사형 씰) 또는 평평한 표면 (축 씰)에 부착하십시오.

2.3 콘 실링 구조

콘 씰 압력 테스트 커플 링은 콘 밸브 코어, 콘 씰 및 스프링으로 구성됩니다.

원추형 씰과 원추형 밸브 코어는 스프링의 사전 압축 추력 아래에서 밸브 본체의 원추형 결합 표면에 단단히 부착됩니다.

콘 밀폐 압력 시험의 내부 구조

콘 씰 특징 : 원추형 밸브 코어와 원추형 씰이 함께 작동하고 씰링이 표면 접촉이며 씰링 효과가 더 좋고 가스와 액체가 보편적입니다.

스프링은 밸브 본체에 통합되어 있으며 풀기가 쉽지 않습니다. 그러나 밸브 몸체와 스풀의 처리 정확도는 상대적으로 높습니다.

업계에서 일반적으로 사용되는 장비로서 유체 압력 테스트 포인트는 광범위한 실제 범위와 편리한 연결 및 샘플링으로 유명합니다. 특히 고압 및 유속에서 유체를 사용하는 경우 많은 장점과 편리함이 있습니다.

그렇다면 장점은 무엇입니까?

장점 1 : 작업은 고압에서 수동으로 완료 할 수 있습니다.

유체가 고압 상태 일 때 작동이 부주의하면 고압이 쉽게 액체가 누출되어 돌이킬 수없는 공정 사고를 일으키고 생명을 위협 할 수 있습니다.

그러나 압력 테스트 호스 커넥터는이를 충분히 고려하여 고압 상태에서 양손으로 간단히 커넥터를 분리하고 닫을 수 있습니다.

장점 2 : 작은 구조

샘플링 및 압력 테스트 위치는 고정되지 않는 경우가 많기 때문에 특정 조건 및 요구 사항에 따라 작업을 수행해야합니다.

따라서 콤팩트 한 형태는 운반 및 엔지니어링에 큰 편의를 제공합니다.

그런 다음 미터와 쉽게 연결할 수있는 기능이 있습니다.

고유 한 목적으로 인해 악기와의 연결을 완전히 고려하여 조작이 쉽고 연결이 견고합니다.

3. 요약

테스트 포인트 어댑터는 유압 시스템의 매우 작은 구성 요소이지만 유압 시스템의 디버깅, 테스트 및 진단에 중요한 역할을 합니다.

압력계 또는 센서를 통해 분해 및 조립없이 다양한 압력 테스트를 완료 할 수 있으며 누출이 없습니다.

유압 시스템에서 압력 테스트 지점 피팅을 합리적으로 설정하면 디버깅, 테스트 및 진단에 많은 편의를 제공합니다.

좋은 적용 효과를 보장하기 위해서는 고품질의 안정적인 제품을 선택하는 것이 매우 중요합니다.

압력 테스트 포인트의 현재 평가가 매우 좋고 제품 디자인이 우수합니다.

큰 유량 출력을 보장하는 동시에 엄격한 품질 심사 기준을 보장하여 제품의 사용 가치를 높일 수 있습니다.

현재 상황에서 볼 때 압력 테스트 커플 링은 주로 다양한 유체 시스템에 유연하게 적용됩니다.

그러나 다른 유체 시스템의 내부 배선과 커넥터의 크기가 다르므로 해당 압력 테스트 지점을 구매하기 전에 미리 흐름 제어를 수행해야합니다.

사이즈가 맞지 않으면 귀찮은 일이기도합니다.

유압 호스 어셈블리 및 피팅의 유형은 무엇입니까?

중국 건설 기계의 급속한 발전으로 유압 호스 어셈블리의 신뢰성은 업계에서 가장 우려되는 문제 중 하나가되었습니다.

유압 호스 어셈블리는 유압 전송 시스템의 기본 요소입니다. 호스 어셈블리의 품질은 유압 시스템과 메인 엔진의 성능에 직접적인 영향을 미칩니다. 호스 어셈블리 고장의 일부는 조인트 코어의 구조에서 비롯됩니다.

호스 커넥터 코어는 주로 SAE 표준, ISO 표준 및 KES 표준을 기반으로하는 연결 구조입니다. 다른 부분은 압착 부 (꼬리 구조)의 구조로, 호스의 외부 재킷과 내부 및 외부 고무층과 일치하여 호스 어셈블리의 성능을 충족시키기 위해 신뢰할 수있는 압착 변형을 형성합니다.

이음 심 압착 부의 구조가 호스의 종류에 따라 설계가 부적절 할 경우 제품 품질 문제가 크게 발생합니다.

따라서 다른 작업 환경에서 호스에 대해 선택된 (설계된) 조인트 코어의 유형도 다르며 합리적인 설계로 고장 발생을 피하거나 줄일 수 있습니다.

1. 호스 피팅의 종류와 특징

전체 호스 조립 산업 전반에 걸쳐 호스 조인트와 호스 사이에는 주로 두 가지 유형의 안정적인 연결이 있습니다. 즉, 완전 보류 호스 조인트와 분리형 호스 조인트입니다.

전체 압착 조인트는 압착기의 8 부분 압착 모듈이 조인트 코어, 호스 및 아우터 재킷을 조립 한 후 호스 조인트를 어느 정도 균일하게 압착하여 호스 조인트와 호스가 전체가되도록하는 공정입니다. .

탈착식 호스 커넥터는 외부 콘과 커넥터 코어가있는 커넥터 코어를 통해 호스를 압축하여 호스가 커넥터 슬리브의 내부 콘에 가까워져 더 큰 결합력을 가진 연결을 형성합니다.

1.1 호스 압착 형태 및 특성

호스 보류 유형은 주로 호스 유형 (또는 내부 및 외부 고무의 크기)과 호스 어셈블리의 압력 환경에 따라 다릅니다.

주로 비 필링 고무 압착, 필링 외부 고무 압착, 내부 및 외부 고무 필링 압착의 세 가지 범주로 나뉩니다.

각 유형의 특성은 다음과 같습니다.

(1) Non-peeling 및 crimping : 호스의 내부 및 외부 고무를 벗길 필요가 없으며 호스 설치 후 압착으로 제품을 완성 할 수 있습니다. 처리 기술은 간단합니다.

이러한 유형의 크림 핑은 GB / T3683, EN853 및 SAE 표준과 같이 상대적으로 얇은 외부 고무 층이있는 강철 와이어 브레이드 호스에 자주 사용됩니다.

(2) 스트리핑 및 압착 : 호스의 외부 고무층을 일정 길이 (외부 고무층이 두꺼움)로 벗겨야하는데, 이는 강선 보강층이이 홈과 더 잘 접촉하도록하는 데 사용됩니다. 자켓.

외력에 의해 재킷이 수축 및 변형되면 강철 와이어가 단단히 고정되어 고압 충격을받을 때 조인트가 빠지는 것을 방지합니다.

이러한 유형의 압착은 주로 GB / T10544, EN856 및 SAE 표준과 같은 강선 권선 호스에 적용됩니다.

(3) 내부 및 외부 고무 스트리핑 및 크림 핑 : 내부 및 외부 고무 층을 일정 길이 (내부 및 외부 고무의 두께)로 벗겨야하며 강선 층과 내부 고무 층이 물결 모양으로 압출됩니다. 일반적으로 GB / T10544, EN856-R13, R15 등에 적합합니다. 사양 (32 개 이상 32 개 포함) 초고압 강선 나선형 호스.

1.2. 원천 징수 형 호스 커넥터

원천 징수 형 호스 조인트는 주로 조인트 코어, 외부 재킷 (너트는 옵션 부품) 및 기타 부품으로 구성됩니다.

1) 공동 핵심 재료, 유형 및 특성

일반적으로 조인트 코어에 사용되는 재료는 20, 35 및 45 강철입니다. 직선 조인트 코어의 경우 변형에 강한 저항력을 가진 35 및 45 강철이 자주 사용됩니다. 벤딩 조인트 코어의 제조 가능성을 고려할 때 일반적으로 20 또는 35 강이 사용됩니다.

열간 굽힘 기술이 대중화됨에 따라 35 강과 45 강을 팔꿈치 조인트 코어에도 사용할 수 있습니다.

조인트 코어의 구조적 특성은 호스 압착 형태와 밀접한 관련이 있으며 구조의 규칙성에 따라 조인트 코어의 유형은 크게 지그재그 구조, 직사각형 구조, 내부 잠금 구조 등으로 구분됩니다.

(1) 일반적으로 미늘 유형으로 알려진 톱니 구조 조인트 코어는 주로 톱니 홈으로 구성되며 빗변과 축 사이의 각도는 일반적으로 20 ° 이하입니다.

세 레이션의 상단은 원 호형 또는 평평하며, 세 레이션의 평면과 짧은면은 매끄럽고 둥근 모서리 (0.2 ~ 0.5mm)로 조립 및 압착시 호스의 내부 고무층 손상을 방지합니다.

이 구조의 조인트 코어는 강한 밀봉 및 인발 저항을 가지며 주로 강철 권선 고무 호스에 사용됩니다.

(2) 직사각형 구조 조인트 코어 : 주로 여러 개의 직사각형 홈으로 구성되며 5 ~ 7 홈 바디는 밀봉 홈을 형성하며 홈 깊이는 일반적으로 0.3 ~ 0.6mm입니다.

홈 상단과 홈 하단 사이의 전이 표면은 일반적으로 반경 0.1mm ~ 0.3mm의 둥근 모서리로 매끄 럽습니다.

조립 및 압착 중에 호스의 내부 고무층 손상을 방지하십시오. 전체 구조는 간단하고 밀봉 성능이 우수하지만 인발 저항이 낮습니다. 이 구조는 수지 호스, 강선 편조 호스 및 기타 유형의 호스에 자주 사용됩니다.

열간 굽힘 기술이 대중화됨에 따라 35 강과 45 강을 팔꿈치 조인트 코어에도 사용할 수 있습니다.

중국 건설 기계의 급속한 발전으로 유압 호스 어셈블리의 신뢰성은 업계에서 가장 우려되는 문제 중 하나가되었습니다.

이음 심 압착 부의 구조가 호스의 종류에 따라 설계가 부적절 할 경우 제품 품질 문제가 크게 발생합니다.

따라서 다른 작업 환경에서 호스에 대해 선택된 (설계된) 조인트 코어의 유형도 다르며 합리적인 설계로 고장 발생을 피하거나 줄일 수 있습니다.

따라서 다른 작업 환경에서 호스에 대해 선택된 (설계된) 조인트 코어의 유형도 다르며 합리적인 설계로 고장 발생을 피하거나 줄일 수 있습니다.

(3) 내부 잠금 구조 조인트 코어, 안티 풀 아웃 구조라고도합니다.

이 유형의 구조는 호스가 호스 조인트에서 빠지는 것을 방지하도록 특별히 설계되었으며 직사각형 구조로 인해 견고성이 보장됩니다.

따라서 내부 잠금 구조 조인트 코어는 실제로 풀 아웃 방지 구조와 직사각형 구조의 조합입니다.

이러한 종류의 조인트는 높은 신뢰성과 긴 수명의 특성을 가지고 있습니다. 주로 가혹한 작업 조건에서 초고압 및 대구경 강선 권선 호스 및 동적 강선 권선 호스 어셈블리에 사용됩니다.

2) 외부 캡 재질, 유형 및 특성

외부 재킷의 재료는 일반적으로 20 강철이며 재료의 우수한 소성 변형은 외부 재킷 치아 압출 고무 튜브와 조인트 코어 씰링을 맞추는 데 사용됩니다.

주로 서로 다른 조인트 코어, 서로 다른 작업 환경, 서로 다른 특정 작업 조건 및 필요한 서로 다른 구조적 형태를위한 많은 유형의 외부 캡이 있습니다.

일반적으로 재킷의 안쪽은 홈이나 톱니 모양으로 구성됩니다. 사각형 홈, 사다리꼴, 지그재그 등이 있으며 다른 유형의 조인트 코어와 함께 사용해야합니다.

일반적으로 사용되는 외부 캡의 구조 유형은 대략 다음 세 가지 유형으로 나뉩니다.

(1) 물결 모양의 톱니 홈 재킷. 물결 모양 재킷의 외부 표면은 주로 매끄러운 원통이며 내부 치아의 빗변과 축 사이의 각도는 25 ° ~ 45 °입니다.

요골 측과 빗변은 0.2 ~ 0.5mm의 둥근 모서리로 연결되며 일반적으로 3 ~ 5 개의 내니로 구성됩니다. 주로 수지 튜브 및 강선 편조 호스와 같은 비 박리 중압 및 저압 호스 어셈블리에 적합합니다. 약한 인발 저항과 간단한 가공 기술로 톱니 구조 및 직사각형 구조 조인트 코어와 함께 사용할 수 있습니다.

(2) 사다리꼴 톱니 홈 재킷. 외부 표면은 매끄러운 원통이고 내부 표면은 일정한 수의 사다리꼴 톱니가있는 홈입니다.

빗변과 축 사이의 각도는 25 ° ~ 45 °이며 각 톱니는 직사각형 홈입니다. 톱니 모양의 상단은 너비가 1 ~ 2mm 인 평면이고 날카로운 모서리는 0.2mm의 둥근 모서리로 전환됩니다.

직사각형 구조 조인트 코어와 함께 사용하여 효과적인 인발 저항을 형성 할 수 있으며, 중압 및 고압 편조 파이프와 와인딩 파이프를 스트리핑하는 데 적합합니다.

(3) 복합 폐포 덮개. 외부 표면은 내부 치아 탈구에 해당하는 T 자형 홈이고 내부 표면은 일정 수의 양측 사다리꼴 치아가있는 홈입니다.

내부 잠금 구조 조인트 코어와 함께 사용하기에 적합하며 초고압 및 대 유량 호스 어셈블리에 사용됩니다.

대규모 건설 기계의 점진적 발전과 함께 유압 시스템도 고압 방향으로 지속적으로 발전하고 있으며 이러한 구조적 형태의 적용이 점점 더 광범위 해지고 있습니다.

2. 조인트 압착 량 선택

다양한 호스 유형 및 조인트 유형에 따라 적절한 압착 량도 호스 어셈블리에 문제가 없도록하는 핵심 요소입니다.

크림 핑의 양은 밀봉 성능, 풀 오프 강도 및 서비스 수명에 직접적인 영향을 미칩니다.

일반적으로 압착 변형의 품질을 판단 할 때 외부 슬리브의 내부 톱니 표면과 조인트 코어의 톱니 홈 사이의 간격이 고무 튜브로 채워져 있는지 확인하십시오.

변형이 만족 될 때만 인발 저항과 밀봉 성능을 보장 할 수 있습니다.

일반적으로 니트릴 고무와 같은 내부 고무 호스의 압착 량은 내부 고무층 압축 (강선 편조 호스의 경우 40% ~ 45%, 4 층 및 6 층 강선 권취 호스의 경우 50% ~ 55%); 수지 튜브와 PTFE 호스의 압착 량은 내부 고무층의 압축 량이 25% ~ 30%가되도록 보장합니다.

봉인을 확보하는 경우 원천 징수 금액이 적을수록 좋습니다. 계산 및 검증을 통해 일정 금액의 원천 징수를 선택합니다.

3. 결론

이 기사에서는 원천 징수 호스 어셈블리에 사용되는 조인트 코어 및 외부 캡의 유형에 대해 설명합니다.

호스 압착에 품질 문제와 고장 유형이있는 경우.

불합리한 호스 압착 구조로 인한 낮은 호스 조립 성능 문제를 피하기 위해 합리적인 압착 구성 및 압착 조인트를 사용하는 이유와 방법을 분석했습니다.

호스 어셈블리의 신뢰성을 효과적으로 개선 및 제어하고 다양한 유압 엔지니어링 기계의 신속한 개발을 강력하게 지원합니다.
