Design of a High-precision and Corrosion-resistant Liquid Inlet System
摘要
Aiming at the shortcomings of the current liquid inlet, such as insufficient precision and corrosion resistance, a high-precision corrosion-resistant liquid inlet device is designed. This design consists of three parts: the host computer, the switching valve and the injection pump. The upper computer controls the channel switching of the switching valve and the injection of the injection pump through the CAN (Controller Area Network) bus. The switching valve and injection pump are protected by corrosion-resistant materials and track protection measures, respectively. In the experiment, the experiment was repeated 5 times with different volumes of ultrapure water, and the calibration curve was established, and the relative standard deviation (RSD) was calculated to be between 0.03% and 2.02% and the correlation coefficient (R2) was 0.99999. The experimental results show that the device has good linearity and high precision, and provides a practical solution for the development of the drive device of the liquid feeder.
