AI Technical Summary

Technical Problem

During long-term use, traditional fume hoods accumulate impurities such as oil and scale on the inner wall of the pipes, leading to blockages and damage. At the same time, the electrical control components have poor heat dissipation in high temperature and high humidity environments, affecting the stability and service life of the equipment.

Method used

A control chassis was designed, which includes a water supply system and heat dissipation components. The PLC controller manages the water pump and solenoid valve to realize automatic cleaning of the water supply pipeline. The cleaning efficiency is improved by combining backwashing components and regulating components, and the temperature of the electronic control components is reduced by cooling fans and water pipe network plates.

Benefits of technology

It effectively removes impurities from water supply pipes, extends equipment lifespan, ensures stable operation of electrical control components in high temperature and high humidity environments, and improves equipment efficiency and reliability.
