Precautions and precision adjustment of weightless scale
In the whole process of application, the weightlessness scale can reasonably maintain the continuity of its loading and the accuracy of its measurement verification. The loading bin of the weightlessness scale must be reasonably equipped with a large hopper that can carry out continuous feeding and its operation. Fully automatic gate valve for refilling. In the weightlessness scale, if the net weight in the control instrument panel reaches the lower limit value of the replenishment, a data signal to open the replenishment gate valve will be transmitted reasonably, so that the gate valve will be opened, and the raw material of the large hopper It will be immediately placed in the upper bin according to the conductive soft connection, and the net weight in the scale body will increase. When the net weight of the scale body on the weightlessness scale reaches the limit value on the set fabric, a data signal to close the gate valve will be sent out reasonably, so that the gate valve will be closed, and the feeding motor will be in the whole process. It has been in operation, in other words the loading is continuous. In the whole process of the weightless scale operation, for these poorly circulating and lighter and thin raw materials, in a relatively short period of time after the gate valve is closed, there will be a part of the net weight that has not been added to the scale body. It is the basis for the machinery and equipment. The data signal transmitted by the sensor carries out PID control. The weight change experienced by the sensor of the weightless scale for a period of time will be reduced, which will immediately cause the data signal to lose frame and control the prohibition. The fabric time time is also set in the control panel, and that time is to close the gate valve. Just started to carry out the calculations. The weightlessness scale has finished the time when the fabric is refilled at the beginning. During this period of time, the feeding motor will keep the frequency before refilling unchanged. In other words, the machine and equipment are in the whole process. Fixed frequency operation.
