Real time online measurement and control system for cutting fluid concentration

YR-C-350Real time online measurement and control system for cutting fluid concentrationUsing the current optical detection instrument, the cutting fluid concentration is continuously detected. The system calculates the concentration deviation based on the set concentration value and the actual concentration value detected. Through a certain control algorithm, the opening size of the control valve is obtained, and then the oil supply flow rate of emulsified oil to the cutting fluid tank is controlled. By controlling the inlet amount of emulsified oil, the ratio of emulsified oil flow rate to clean water flow rate can reach a certain range to ensure that the cutting fluid concentration value meets the set requirements.

Principle of detector: The light emitted from the LED enters the sapphire prism from one side through the optical fiber and reaches the contact surface between the prism and the cutting fluid. According to the different refractive indices of the cutting fluid at the contact surface, a part of the light is completely reflected to the other side of the prism, and the position of the total reflected light will change due to the change in critical angle (the critical angle will be different due to the different refractive indices of the liquid). The linear array CCD is used to detect the position of the light that is completely reflected back, and each position corresponds to the refractive index. There is a correlation between the refractive index and the concentration of cutting fluid.

CYR-C-350Real time online measurement and control system for cutting fluid concentrationIt is an online cutting fluid concentration measuring instrument developed based on the principle of refraction. Directly installed in the cutting fluid pool for concentration monitoring and control, or on pipelines, without mechanical action measurement, ensuring stability and long service life.
1. Real time measurement and control of cutting fluid concentration can be achieved; It can avoid situations where the concentration is too high or too low due to untimely manual measurement. By setting upper and lower limit alarms for cutting fluid concentration, on-site personnel can be reminded to handle it in a timely manner or automatically adjust it.
2. After adopting the cutting fluid online monitoring system, the labor intensity of manual labor can be reduced. Or reduce the number of testing personnel to achieve the goal of lowering labor costs.
3. Eliminate artificial imbalance of cutting fluid concentration and achieve automatic proportioning of cutting fluid concentration; It has a significant effect on improving product quality and enhancing work efficiency.
4. Capable of achieving effective supervision of equipment operation by scheduling and management departments; Through Ethernet networking, the concentration data of all machines can be transmitted to the manager's computer, providing reference for their decision-making.
5. Realize efficient operation and protection of equipment. Concentration management, as a data node, can be integrated into future smart factories.
6. After adopting the online detection system for cutting fluid concentration, the cost of annual cutting fluid usage and tool wear caused by improper concentration management will be significantly reduced.

Hunan Chuyi Measurement and Control was founded in 2008 as a high-tech company. Since its establishment, it has been specializing in the research and production of cutting fluid online concentration meters, real-time monitoring systems for cutting fluid concentration, and online cutting fluid concentration sensors. Cutting fluid online concentration meters are widely used in the machining and manufacturing industries. The real-time monitoring system for cutting fluid concentration launched by Chuyi Measurement and Control (CYMC) is very suitable for measuring and controlling cutting fluid concentration in precision machine tools due to the use of critical angle total reflection measurement technology. Due to its diverse range of installation adapters, the cutting fluid online concentration meter is suitable for installation in most workplaces.
