AI Technical Summary

Technical Problem

Traditional membrane electrode surface cleaning relies on manual experience to control temperature, lacking a precise real-time monitoring and feedback mechanism, resulting in large temperature fluctuations, affecting the performance of ultrasonic cavitation effect and easily damaging the membrane electrode material.

Method used

A temperature sensor is used to monitor the temperature of the cleaning solution in real time, and the power of the electric heating element is automatically adjusted by a PLC controller to achieve precise temperature control. At the same time, the use of an ultrasonic generator and an electric telescopic rod ensures the stable fixation of the membrane electrode and the uniformity of the cleaning solution.

Benefits of technology

Precise temperature control was achieved during the membrane electrode cleaning process, avoiding damage to the membrane electrode due to improper temperature, enhancing cleaning efficiency and effectiveness, and ensuring the service life of the membrane electrode.
