(1)机具启动使用三相电源,起动后观察电机旋转方向是否正确,观察其工作电压是否符合要求,一般应在标定值±10%范围内变化;使用单相电源的,应检查线路和输电设备容量是否足够。燃烧器点火不着,稍停片刻再点火,如三久ACF型烘干机第一次点不着火,要求过30s再按“再点火”键,再按“干燥”键。(2)进料要求进入烘干机的谷物,含杂一般应小于2%~3%。含 (1) Start the machine with three-phase power supply, after starting to observe the motor rotation direction is correct, observe its working voltage is in line with the requirements, generally should be within ± 10% of the calibration value range change; use single-phase power supply, should check the line and power transmission Equipment capacity is sufficient. Ignition of the burner, a short pause then ignition, such as three long ACF-type dryer for the first time point is not fire, asked for 30s and then press “and then ignition ” button, and then press “dry ” button. (2) feeding requirements into the dryer grain, mixed should generally be less than 2% to 3%. Contains
