Principles and advantages of weightlessness scale
The weightlessness scale is a kind of connected weighing and measuring equipment that has been manually manipulated in various industrial scales in the mid-80s. Now, more and more generation workshops are beginning to use weightlessness scales. So what are the advantages of the principle of weightlessness scale? The working principle of the weightless scale: The powder material is added from the silo to the buffer silo. When the buffer silo material level reaches the upper limit, the buffer silo feed valve closes, and the weighing silo feed valve opens at the same time, and the material enters the weighing silo, and the weighing silo material reaches the upper limit. After that, the weighing bin feed valve is closed, and the buffer bin feed valve is opened for feeding. When the material in the weighing bin reaches the lower limit, the buffer bin feeds the weighing bin, so the cycle continues the feeding process. The material enters the weighing bin and is measured at the same time. The weight of the material in the heavy warehouse is detected by the sensor as the original weight value, and the reamer is turned on, and the material is conveyed along the rotation direction of the reamer. As much material is conveyed, the weighing warehouse will cut how much material to measure the conveying amount. For example, 1s ago The weight of the material in the weighing bin is measured as X, and the weight of the material in the weighing bin is measured as Y after 1s, then the weight of the material in the 1s is xy. Based on this calculation, the material lost in the system is accumulated in time , It will reach the total weight of the materials placed in a period of time. This is the root principle of the dynamic measurement of the FB-CWLF type high-precision loss-in-weight powder measurement control system. The advantage of the weight-loss scale is that the transmission is through and the measurement is accurate. Scales, reduction scales, weightless feeders) adopt private stainless steel materials and advanced flow aid systems to implement smooth material transportation, accurate measurement, and dexterity and low delivery costs; high-precision weightlessness scales (weightlessness metering scales, weightlessness batching scales, weightlessness Feeder, reduction scale, weightlessness batching scale) adopt a weighing method similar to static weighing to achieve measurement accuracy ≦±0.4%, which effectively improves product texture and saves cost; static standard general weightlessness scale system comes with 3 measuring forces For the sensor and calibration ring, the calibration is to put a calibration weight on it and directly calibrate it statically, which is not only accurate, but also simple and fast to operate.
