Kehua Heavy Industry will introduce the working principle of the screw scale in detail. The material is transported from the feeding port to the metering reamer connected below through the screw conveyor. The weighing sensor installed on the metering reamer detects the weight of the material and generates a The voltage signal proportional to the weighing load is sent to the controller, and calculated together with the preset reamer speed data to obtain the instantaneous flow rate and accumulated weight value. The control system compares the actual flow signal with the set flow signal, outputs the control signal to the frequency converter through PID adjustment, and dynamically adjusts the speed of the feeding reamer to achieve quantitative feeding. Kehua Heavy Industry is a professional manufacturer of spiral scales, electronic belt scales, loss-in-weight scales and quantitative feeders in the north. Welcome new and old customers to visit the factory.

　　The spiral scale produced by Kehua has the following advantages:

　　1. Adopt advanced feedforward adjustment system 3U-S control system.

 　　2. The powder balance lock is adopted to ensure stable feeding.

 　　3. It adopts dual control function and adjusts the powder balance lock and metering screw at the same time, which improves the metering accuracy.

 　　4. The large feeding port, variable diameter, variable distance and overflow outlet are adopted to ensure that the material sinks evenly, is stably controlled, does not collapse, and does not flood or channel material.

 　　5. Adopt high-precision digital weighing module and digital transmission technology, with simple lines, no adjustment components, high resolution, no signal attenuation, and strong anti-interference.

 　　6. The controller adopts touch display technology, Chinese and English graphical display, wizard operation mode, simple operation, no memory required.

 　　7. It can be connected to 485 communication, CAN communication, DCS, PLC and other interfaces.

 　　8. It adopts GPRS wireless data transmission function, which can provide functions such as short message report, remote diagnosis, and scale calibration.
