المنطقة 1 والمنطقة 2 بطارية ليثيوم واقية من الانفجار الصف التمييز وإصدار الشهادات

في صناعة البتروكيماويات والتخزين والخدمات اللوجستية وسيناريوهات التشغيل الأخرى حيث توجد غازات قابلة للاشتعال والانفجار ، يجب تكييف بطاريات الليثيوم المقاومة للانفجار والمجهزة برافعات شوكية كهربائية مع مستويات مختلفة من المناطق الخطرة ، منها المنطقتان 1 و 2 هما الانقسامات المشتركة.

الاختلافات الأساسية في درجات واقية من الانفجار بين المنطقة 1 والمنطقة 2

الاختلافات تعريف المنطقة الخطرة

تشير المنطقة 1 إلى منطقة خطرة حيث تستمر مخاليط الغازات المتفجرة ، أو توجد لفترة طويلة ، أو تحدث بشكل متكرر ، ويكون خطر الانفجار في مثل هذه البيئة دائمًا على مستوى عالٍ ؛ تشير المنطقة 2 إلى منطقة لا تظهر فيها مخاليط الغازات المتفجرة إلا من حين لآخر أثناء التشغيل غير الطبيعي وتستمر لفترة قصيرة ، ويمكن التحكم في خطر الانفجار نسبيًا.

الاختلافات في متطلبات الأداء واقية من الانفجار

بالنسبة لبيئة المنطقة الأولى ، تحتاج بطاريات الليثيوم المقاومة للانفجار إلى قدرات حماية أكثر صرامة ضد الانفجار ، ويجب اعتماد هياكل مقاومة للانفجار مثل الهياكل المقاومة للانفجار والآمنة جوهريًا لضمان عدم تحولها إلى مصدر التفجير تحت أي ظروف عمل. بالنسبة لبطاريات الليثيوم المقاومة للانفجار في بيئة المنطقة الثانية ، يمكن اختيار هياكل مقاومة للانفجار مبسطة نسبيًا مثل زيادة السلامة ، طالما أنها لا تولد طاقة كافية للانفجار أثناء التشغيل العادي.

متطلبات الاعتماد لبطاريات الليثيوم المقاومة للانفجار في المنطقتين 1 و 2

شهادة أساس قياسي

يجب أن يفي كلا النوعين من بطاريات الليثيوم المقاومة للانفجار بمتطلبات المعايير الوطنية المقاومة للانفجار واجتياز اختبار الأداء المقاوم للانفجار وإصدار الشهادات للمؤسسات العادية. من بينها ، يعد مشروع اختبار الشهادة لبطاريات الليثيوم المقاومة للانفجار في المنطقة 1 أكثر شمولاً ، حيث يغطي الأداء المقاوم للانفجار وحماية الدائرة القصيرة وحماية الحمل الزائد والعديد من الاختبارات الصارمة الأخرى في ظل درجات الحرارة القصوى ؛ يركز مشروع اختبار بطاريات الليثيوم المقاومة للانفجار في المنطقة 2 على التحقق من الانفجار في ظل ظروف التشغيل العادية.

متطلبات الصيانة بعد التصديق

بغض النظر عما إذا كانت تتوافق مع بطارية الليثيوم المقاومة للانفجار في المنطقة 1 أو المنطقة 2 ، فمن الضروري إجراء إعادة فحص منتظمة للأداء المقاوم للانفجار بعد الحصول على الشهادة. في الاستخدام اليومي ، من الضروري أيضًا اتباع مواصفات التشغيل بدقة لتجنب فشل الأداء المقاوم للانفجار بسبب التلف أو الشيخوخة من صنع الإنسان ، ولضمان سلامة العملية في المنطقة الخطرة المقابلة.
