| In order to improve the reliability of the actuator used outdoors, waterproof countermeasures of actuator are studied. According to the actuator′s structure and heat transfer theory, a temperature and humidity model for gas inside the actuator is established to achieve an online calculation of temperature and humidity of gas inside the actuator. By the comparison of the simulation value and experimental measurement of temperature and humidity, the temperature and humidity model is verified and the production reason of accumulated water inside the actuator is analyzed. According to the calculation results of the temperature and humidity model, the solution of installing waterproof ventilated valve to solve the problem of accumulated water inside the actuator is proposed, and experimental comparison is conducted. |
