The weight loss scale can be called a powder equipment scale or a weight loss feeder, and the weight loss scale has a very accurate measurement verification effect, which has already been effectively certified in the measurement verification of coal powder. The design principle of the weight loss scale is set according to the circulation performance of the material, so the weight loss scale principle is still very important. In the basic principle of loss-in-weight weighing, the electric vibrator for feeding and the bucket used for weighing are connected by conductive soft connection, so all the forces are completely separated, and the electric vibrator for cutting materials is used. The conductive flexible connection, but its force, and the weighing bucket in general, are mainly composed of three sensors with the same tensile force, and are connected by the inner material column in the weighing bucket. In the basic principle of loss-in-weight scale, when the electric vibrator starts to weigh the head feeder, and the hopper is basically qualified in the given amount, the instrument panel in the weight-in-loss scale will show Stop the signal of the feeder, after a period of time, the electric vibrator of the feeding will start to cut it, and when the feeding is limited in weight, it will stop all the feeding work middle.
In fact, the basic principle of weightlessness is such a continuous action, and whether it is the total flow of raw materials or the weight of the feeder, it is basically done using this basic principle, so people will use this kind of machine The device is called a weightless scale, but the basic principle of a weightless scale is far more than that. And in the principle of weight loss, pre-watering is an effective way to stabilize the automatic control system, while people often use high-frequency sampling and storage technology, the key is to properly control the change in the amount of dry material, And finally achieve the effect we expected, but not all effects are good. In terms of solving the problem of zero drift of the weightlessness scale, it can be detected and tested by the product, and at the same time ensure that the raw material is in a stable state, use the soft starter equipment to control all the water supply and drainage equipment, which can be effective Consider the problem of water flow adjustment in terms of adjustment.
However, the technical requirements in the basic principle of weightlessness are also relatively strict, because the soft starter has relatively good linear control characteristics, which can effectively ensure the precision requirements of all water supply and drainage, and also separate the two methods of opening and closing Open, for people to choose and use, it is very convenient for users.
