Troubleshoot industrial ultrasonic humidifier

　　1, for completely fog-free fault, first detect whether the power supply voltage is normal, if there is no voltage, then check from the power supply path step by step, which is no different from the general power circuit maintenance, do not need to be described. However, it should be noted that because the fan is connected to the fuse and the switch, the fault location can be quickly distinguished by observing whether the fan is running after the switch is turned on. If the fuse or transformer burned, both may be caused by high mains power, it may also be caused by the damage of components in the circuit, should be cut off to measure the resistance of the relevant parts, eliminate the short circuit point, and then power into the next overhaul.

　　2, transducer is a unique component of this kind of electrical appliances, but also fault prone parts. Too much transducer scale deposition is a common reason for small fog volume, and transducer damage, depending on the degree of damage, may cause complete fog, may also cause small fog volume. The reasons for the transducer damage are: first, there is too much scale in the process of use, which is not removed for a long time and the electricity works, which is in a state similar to "dry burning", resulting in the transducer burning out; The other is rough operation during descaling, resulting in stripping and scrap of the electroplating layer. For users, it is required to observe often. When scale is large, it should be descaled in time. It is best to use special descaling agent for descaling. The inspection of the transducer is mainly to check whether there is corrosion, electroplating stripping blister, pitting, uneven convex and concave and defect, one of these situations should be replaced. If there is no problem, the multimeter can be used to measure the resistance between the two poles. If there is leakage resistance, it can be carefully cleaned with anhydrous alcohol, remove rust and dirt and dry it before installation. Generally, it can be used normally. Replace the transducer, the appearance specifications are best consistent with the original, otherwise the seal is not good will leak, it is difficult to deal with under general conditions.

　　3, high power tube is also one of the common fault components, generally breakdown damage, and breakdown of the reason, mostly because of transducer damage and joint damage, resulting in fuse burned off and completely fog free. A few also have performance deterioration, so that the circuit can not vibration and complete fog, or the oscillation is weakened so that fog can not be increased. The inspection of the high-power tube belongs to the routine inspection, and it is unnecessary to repeat, but it should be noted that the high-power tube used in the industrial ultrasonic humidifier has special requirements. The main parameters are: BVceo≥200v Icm≥6A Vces≤1.5V(Ic=2A) β≥ 50Ft ≥10MHz. Some EXCELLENT TRIODE IN OTHER CIRCUITS, IN THE INDUSTRIAL ULTRASONIC HUMIDIFICATION CIRCUIT is not necessarily competent, THE use OF INAPPROPRIATE TRIODE, WILL make THE circuit can not work or fog can not increase.

　　4, potentiometer and fine adjustment resistance need to pay attention to. Because the industrial ultrasonic humidifier is usually in the environment humidity is large, potentiometer and fine resistance easy to rust, and the panel of the potentiometer is often used for a long time wear, easy to produce poor contact fault problem, will cause no fog, spray when big or small or sometimes no, should be cleaned or replaced.
