为监控风量，抽风机65设有风压收集口和风压开关，风压收集口为倒喇叭口，其倒置于抽风机65出风口上方，用于收集风量至风压开关，风压开关电连接控制装置。工作时，风压开关在风量过低或过高时触发输出信号给控制器，控制装置据此执行声光示警，确保风机异常能及时报警。In order to monitor the air volume, the exhaust fan 65 is provided with a wind pressure collection port and a wind pressure switch. The wind pressure collection port is an inverted bell mouth, which is placed upside down above the air outlet of the exhaust fan 65, and is used to collect the air volume to the wind pressure switch.
