Comprehensive technical engineering guide on Fire Pump Design Nfpa20 Guide Guide. Detailed design principles, NFPA/EIT standards compliance, calculations, and safety maintenance workflows.
1. มาตรฐานและกฎหมายที่ใช้ออกแบบ Fire Pump
In industrial and commercial facility design, maintaining compliance with NFPA standards and local EIT building safety codes is the fundamental baseline for protecting human life and critical corporate assets. This technical section outlines the essential design criteria, operational boundaries, and code mandates governing this engineering domain.
2. ประเภทของเครื่องสูบน้ำดับเพลิง
System sizing and component selection require rigorous hydraulic, electrical, or thermodynamic calculations. Engineering parameters must account for worst-case environmental conditions, emergency back-up power constraints, and structural load limits.
| ชนิดปั๊ม | ลักษณะ | เหมาะกับ |
|---|---|---|
| Horizontal Split-Case | เสื้อปั๊มผ่าครึ่งแนวนอน ถอดซ่อมง่าย ทนทานสูง มีขนาดให้เลือกกว้างที่สุด (ถึง 5,000 GPM) | โรงงานและอาคารขนาดกลาง-ใหญ่ที่มีถังน้ำบนดินหรือระดับน้ำสูงกว่าปั๊ม เป็นชนิดที่นิยมที่สุด |
| End Suction | ทางดูดเข้าปลายเสื้อปั๊ม โครงสร้างกะทัดรัด ราคาต่ำกว่า Split-Case | ระบบขนาดเล็ก-กลาง (โดยทั่วไปไม่เกิน 1,500 GPM) พื้นที่ห้องปั๊มจำกัด |
| Vertical In-Line | ติดตั้งคั่นในแนวท่อ ประหยัดพื้นที่มากที่สุด | ระบบขนาดเล็ก อาคารพาณิชย์ที่พื้นที่จำกัดมาก |
| Vertical Turbine | ใบพัดหลายชั้นจุ่มลงในน้ำโดยตรง เป็นชนิดเดียวที่ NFPA 20 อนุญาตให้สูบจากระดับน้ำต่ำกว่าปั๊ม | ถังเก็บน้ำใต้ดิน บ่อน้ำ หรือแหล่งน้ำเปิดที่ระดับน้ำอยู่ต่ำกว่าห้องปั๊ม |
3. การเลือกขนาดปั๊มและเส้นโค้งสมรรถนะ (Performance Curve)
