Guidelines on Installing Carbon‑Monoxide Gas Detectors
Installation of carbon monoxide gas detectors requires comprehensive consideration of multiple factors to avoid potential troubles. Personnel proficient in installing this type of instrument are generally capable of installing other gas detectors.
① For medium‑to‑large workshops with potential carbon‑monoxide leakage, relevant specifications recommend one monitoring point every 3‑6 meters.
② For unattended small pump houses with non‑continuous operation, potential CO leakage risks shall be taken into account. Especially in northern regions, doors and windows are closed in winter; slight CO leakage may rapidly reach toxic concentration levels. One monitoring point shall be arranged at the downwind side of prevailing wind; multiple points are required for large‑size workshops.
③ For sites with possible CO leakage such as large‑scale generator sets, hydrogenation units in refineries, electrolysis workshops and hydrochloric‑acid synthesis workshops in electrochemical plants, install detectors on the plane above potential leakage sources.
After installation is completed, inspection and trial‑run test shall be performed. Acceptance can be carried out only after normal operation is verified, so as to guarantee reliable long‑term performance.
Note：The following paragraphs describe hydraulic press equipment, irrelevant to CO gas detector, kept translated as per original text: The power unit and electrical system are arranged separately, equipped with plate‑type integrated oil circuit and program‑control circuit. Key components of hydraulic and electric control systems are imported. Centralized push‑button control supports two operation modes: adjustment mode and semi‑automatic mode. Semi‑automatic mode includes manual feeding with floating‑mold process and automatic injection feeding with floating‑mold process. Working pressure, pressing speed, high‑pressure down‑stroke, no‑load fast down‑stroke and ejection stroke can be adjusted according to forming requirements of different products. Four digital time relays for high‑speed mold‑closing pulse, slow‑press delay, pressure‑holding delay and demagnetization delay ensure finished‑product quality.
