무엇 상황 필요 가져 가기 고려 사항 언제 보정 가연성 가스 감지기 % 3f
before the calibration of the combustible gas detector, it should be ensured that there is no combustible gas in the surrounding environment of the combustible gas detector. If there is combustible gas, the rainproof cover should be removed first, and a certain amount of clean air should be filled in, and then the sample gas should be continuously introduced. , to ensure the accuracy of the calibration.
In principle, the calibration of combustible gas detectors should use the standard gas that has been certified by metrology and matches the gas to be detected.
the measured gas is a hydrocarbon mixture, isobutane is selected as the sample gas, followed by propane.
For non-hydrocarbon mixtures or hydrocarbon mixtures with a large difference in heat generated during combustion of gases with lower explosive concentration, as a last resort, easily available and stable single-component fuels such as butane, isobutane, and propane can be used as samples. gas. At this time, the range of the alarm must be adjusted according to a certain detection signal conversion relationship.
Fault Analysis of Combustible Gas Detector
가연성 가스 검출기 are 검출기 설치 및 사용 산업 및 토목 건물 저것 응답 to single or multiple 가연성 가스 농도. 거기 있다 two types of 가연성 가스 검출기 저것 대부분 사용 in daily life: 촉매 가연성 가스 검출기 및 반도체 가연성 가스 검출기. 레스토랑, 게스트하우스, 홈 워크샵 및 기타 장소 저것 용도 가스, 천연 가스, 및 액화 석유 가스 주로 사용 반도체 유형 가연성 가스 검출기, and 산업 장소 저것 방출 가연성 가스 및 가연성 증기 주로 사용 촉매 유형 가연성 가스 감지기.
가능 고장 및 원인 분석 의 가연성 가스 검출기:
1. 거기 is no display when the combustible gas detector is turned on. Cause of failure: Membrane switch failure; battery lead broken: The battery voltage is seriously insufficient.
2. 거기 is only a minus sign when the combustible gas detector is turned on, and there is no count when you press the "voltage" button. Cause of failure: The regulated power supply is faulty or its output side is short-circuited.
3. There is only a decimal point when the combustible gas detector is turned on. Cause of failure: There is a damaged ring in the sensing element; or a component in the bridge circuit is desoldered.
4. The 가연성 가스 감지기 does not alarm if it exceeds the limit. 원인 of failure: The ring of the ringer is damaged: the alarm circuit is disconnected.
5. The accuracy of the 가연성 가스 검출기 cant be adjusted to the standard gas sample. Cause of failure: the explosion-proof cover is seriously dusty; the sensor is aging.
