我们综合了国内几种较先进的液面加压控制系统的特点,针对气控技术的关键,设计制造了适用于铝合金低压铸造的801型低压铸造液面加压控制系统.该装置经实验室冷态空调,热态实调以及生产实际使用(某厂浇注130汽缸盖)证明,它的工艺性能稳定可靠,加压速度线性范围宽,加压速度可调,稳压压;打和保压压力能跟踪液面变化自动补偿,加压工艺可完全再现.本装置并附有加压工艺检测装置和金属液面测量部分,后者是根据大连工学院成果设计的.
Based on the characteristics of several advanced liquid level pressure control systems in our country, we design and manufacture a 801-type liquid pressure control system for low pressure casting of aluminum alloy according to the key of gas control technology. Room cold air conditioners, hot real tune and the actual production (a factory pouring 130 cylinder head) proved that its process performance is stable and reliable, linear pressure range of speed, pressure speed adjustable, steady pressure; The pressure can track the liquid level automatically compensate for changes in the pressure process can be completely reproduced.This device is accompanied by a pressurized process detection device and the metal level measurement section, the latter is based on the results of Dalian Institute of Technology design.
