Moment-adjustable fume hood control system
The invention discloses a moment-adjustable fume hood control system. The system comprises a fume hood, a motor, a Hall element and a controller, wherein the motor is fixedly installed at the top of the fume hood; the Hall element is fixed on the motor; a fan and a gas concentration detector are also arranged in the fume hood; and the controller is arranged in the fume hood. The system has the beneficial effects that a Hall sensor is used for detecting a current value of the motor, the controller converts the current value of the motor into the torque of a moving door of the fume hood, when the moving door of the fume hood slides downwards under the action of external force, the torque of the moving door is increased, and after the torque reaches a set torque value, the controller increases the current value of the motor, and the working power of the motor is improved, so that the moving door of the fume hood can be automatically lifted, the moving door can be quickly lifted when encountering a relatively large torque in the descending process, an operator is better protected, and the use safety of the fume hood is ensured.
本发明公开了一种力矩可调式通风柜控制系统,包括通风柜、电机、霍尔元器件和控制器,所述电机固定安装在通风柜的顶部,所述霍尔元器件固定在电机上,所述通风柜内部还设置有风机和气体浓度检测仪,所述控制器设置在通风柜内部。本发明的有益效果是:霍尔传感器用于检测电机的电流值,控制器根据电机的电流值换算成通风柜的移动门的扭矩,在通风柜的移动门受外力作用下滑移动时,移动门的扭矩变大,达到设定扭矩数值后,控制器增大电机的电流值,提高电机的工作功率,使通风柜的移动门能够自动抬高,实现在移动门下降过程中遇见较大力矩的情况下快速回升抬起,以对操作者的进行更好的保护,保证了通风柜使用的安全性。
