테스트 인젝터용 ISO 교정 오리피스 플레이트
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.
Each plate features a single precision-drilled hole (Ø 0.4 – 0.8 mm) for controlled delivery under ISO 7440 / 14681 test conditions.
Calibrated orifice plates are precision reference elements used in ISO 7440 and ISO 14681 test injectors.
They define the flow-rate reference in the injector assembly, ensuring identical test conditions and comparable pump-delivery results worldwide.
Each plate corresponds to a Bosch reference and a nominal bore diameter between 0.4 mm and 0.8 mm.
Key Benefits

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.
