(0 리뷰)

ISO 테스트 인젝터(ISO 7440 / ISO 14681)용으로 설계된 정밀 교정 오리피스 플레이트입니다. 0.4mm부터 0.8mm까지의 직경으로 제공되며, 디젤 펌프 교정 시 반복 가능하고 표준화된 유량 조건을 보장합니다.

Marbed 84.50.V series orifice plates are reference components for ISO test injectors.
Manufactured to ISO 7440-2 tolerances, they define the fuel-flow reference during pump testing and ensure consistent results across benches.

Each plate features a single precision-drilled hole (Ø 0.4 – 0.8 mm) for controlled delivery under ISO 7440 / 14681 test conditions.

자주 묻는 질문

이 오리피스 플레이트는 엔진에 사용하는 건가요?

아니요. 이는 교정 벤치에서 ISO 테스트 인젝터에만 사용되는 참조 구성 요소 입니다.

흐름 값은 어떻게 결정되나요?

각 플레이트의 보어 직경은 ISO 7440-2에 따른 기준 유량을 정의합니다. 유량은 교정 오일 ISO 4113을 사용하여 검증됩니다.

오리피스 플레이트는 언제 교체해야 합니까?

ISO 4008-3 부록 B 유지 관리 간격을 따르거나 유량 편차가 허용 오차를 초과하면 교체하세요.

이 제품이 Marbed 테스트 인젝터와 호환이 되나요?

네, ISO 7440/14681 인젝터(유형 II, III, VII, IX 및 동등 제품)를 사용할 수 있습니다.
