ميزات المنتج
- Integrated Vacuum/Atmosphere/Positive/Negative Pressure Multi-Mode System
Integrates temperature control, vacuum furnace, vacuum pump, gas path, pressure protection, gas flow control, positive/negative pressure display, and water circulation pump into one unit. The water circulation tank and furnace body are separate designs. It can accept various gases such as hydrogen, نتروجين, الأرجون, أول أكسيد الكربون, والأكسجين, and supports switching between vacuum (100Pa-10⁻¹Pa) and micro-positive pressure (≤10kPa) modes.
- Water-Cooling Protection System for Comprehensive Cooling of Key Components
Water cooling covers the furnace opening, furnace door, and furnace top of the furnace inner shell, with 1-inch water cooling pipe interfaces. This effectively reduces the temperature of seals and the furnace body, extending equipment lifespan and ensuring vacuum sealing performance.
- 6-20mm Thick Furnace Steel Plate, Pressure Resistance 0.1MPa
The furnace steel plate is 6-20mm thick, double-sided welded, and can withstand a positive pressure of 0.1MPa. The robust and durable structure ensures safe operation under both positive and negative pressure conditions.
- Pressure Protection System, Automatic Safety Pressure Relief
The system receives signals from an electrical contact pressure gauge or pressure sensor, driving the control module to close the electromagnetic inlet valve and activate the electromagnetic exhaust valve and alarm, releasing pressure from the exhaust port. An audible and visual alarm buzzer sounds. This effectively prevents dangers caused by exhaust port blockage or excessive pressure.
- Three-Temperature Zone Design, توحيد درجة الحرارة ممتازة
The system employs a three-temperature zone design, with silicon carbide heating elements installed on both sides of the furnace chamber, forming a double-sided heating field. دقة التحكم في درجة الحرارة هي ±1 درجة مئوية, and the maximum heating rate is 45℃/min, meeting the sintering process requirements of different materials.
