Abstract：

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.
