分析 の 共通 問題 および トラブルシューティング 方法 対象 可燃性 ガス 検出器
差出人 経験 の 作業 入力 ガス 検出器 産業, there are 常に 一部 問題 それ 初めて ガス アラーム ユーザー しない 完全に 理解する 中 使用 プロセス. で 分析 の 共通 障害 の 可燃性 ガス 検出器, there are また 多くの 例 of 可燃性 ガス アラーム 障害 原因 by 不適切 使用 by ユーザー. this article focuses on the common problems of point type gas detectors, which lead to the problem of ユーザー 使用 ガス 検出 アラーム デバイス。
共通 障害 of 固定 ガス 検出器 are mainly caused by 不適切 use by users, lack of 理解 of 検出器 性能, 不適切 機器 選択, 失敗 of users to 構築 準拠 to 標準 要件, and 不十分 メンテナンス。 The フォロー 主に 分析 the 理由 for the 誤動作 of 可燃性 ガス 検出器 使用済み by users, and 提案 方法 使用 可燃性 ガス 検出器 正しく to 最小化 発生 の ガス アラーム 障害。
まず, 不適切 使用 作成者 ユーザー
第二に, the 構築 プロセス is not 標準化されています。
Non standardized construction processes can cause combustible gas detectors to detect faults during use. If the combustible gas detector is not located near the equipment where the combustible gas is easy to leak, or is installed adjacent to the Whole-house fan, the leaked combustible gas cannot be fully diffused near the combustible gas detector, so that the leakage danger cannot be detected by the combustible gas detector in time. For combustible gas detectors in residential areas, they should be installed near gas pipelines and stoves in the kitchen. When the household is using natural gas, the gas detector should be installed on the ceiling within 300mm of the ceiling; When households use liquefied petroleum gas, gas detectors should be installed within 300mm of the ground. If the combustible gas detector is not reliably grounded and cannot eliminate electromagnetic interference, it will inevitably affect the voltage and cause inaccurate detection data. Therefore, the combustible gas detector should be reliably grounded during the construction process. The combustible gas alarm and wiring terminals are located in areas prone to collision or water ingress, causing open or short circuits in electrical circuits. Welding must use non corrosive flux, otherwise the corrosion at the joint will detach or increase the line resistance, which will affect normal detection. Do not drop or throw the detector onto the ground. After construction, debugging should be carried out to ensure that the combustible gas alarm is in normal working condition.
第三に, メンテナンス および 維持
To detect the concentration of combustible gases, a combustible gas detector must communicate with the detection environment. Therefore, it is inevitable that various polluting gases and dust in the environment enter the detector, and the damage caused to the working conditions of the detector is objective. The working environment of combustible gas detectors is relatively harsh, and many are installed outdoors, Poor maintenance and upkeep will result in errors or failure to detect combustible gas alarms. Therefore, regular cleaning and maintenance of combustible gas detectors is an important task to prevent malfunctions. Grounding should be regularly tested. Failure to meet standard requirements or not being grounded at all can also make combustible gas detectors susceptible to electromagnetic interference and cause malfunctions. Prevent aging of components. From the perspective of reliability, it has also been proven in practice that systems with combustible gas detectors that have been in service for more than 10 years tend to experience an increase in faults caused by component aging. Therefore, if the service life exceeds the specified requirements, they should be replaced in a timely manner.
