锻造石墨喷雾自动配比系统设计

Design on automatic proportioning system for graphite spray in forging

针对计量泵由于本身结构和石墨湾液物理特性限制所导致的无法长时间正常使用及价格昂贵的问题,设计了一种通过液位计以及折光仪判断浓度的锻造石墨喷雾自动配比系统,利用液位计实现了墨与混合溶液的体积配比,同时利用折光仪实时监控石墨溶液浓度。此设计能够排除人工配比干扰,有效地避免了现有控制方式伴随的问题,即使在长时间运行后也不会造成硬件损坏。并且利用配比后的浓度检测以及浓度微调功能,将配比浓度完全控制在设定的浓度范围内。同时具有非常好的可兼容性,便于衔接各种不同的喷雾系统。相较以往的配比系统更稳定、更实用、更具优势。

For the problems that the metering pump conldnot be used normally for a ling time caused by the limitation of its structure and the physical properties of graphite solution and the expensive price of metering pump a graphite spray automatic proportioning system in forging that judged the concentration by liquid level sensor and refractometer was designed,namely,the liquid level sensor was used to realize the volume ratio of graphite and mixed solution,at the same time,the refractometer was used to monitor the concentration of graphite solution in real time.Then,this system could eliminate artificial proportioning interference,effectively avoid the problems associated with the existing control mode,and do not cause the hardware damage even after long-term operation.Furthermore,this system uses the concentration detection and concentration fine-tuning function after the proportioning to completely control the proportioning concentration within the set concentration range.At the same time,it has very good compatibility,which is convenient for connecting various pray systems.Compared with the previous proportioning system,it is more stable,more practical and more advantageous.
