Method for physical calibration of electronic belt scale
First, the technical points in the plan (1), scale body structure design. (2) Requirements for symmetric heavy sensors. (3), speed sensor type. (4) Requirements for the display controller. Second, the correct selection When selecting an electronic belt scale , the user should generally consider the requirements of accuracy, weighing range, scale type, function and so on. First, choose the accuracy that meets your needs. Third, the correct installation and commissioning In order to ensure the accuracy and reliability of the electronic belt scale, the following points should be achieved. (1), the installation of scales and instruments should pay special attention to the selection of suitable environmental conditions, such as small surrounding vibration, low relative humidity, weatherproof erosion and sun exposure, especially should be far away from strong magnetic fields and high heat sources, good environmental health . The scale frame should not be too close to the active roller and the blanking point, and it must meet the specified requirements. (2) The conveyor truss of the fixed electronic belt scale must have sufficient rigidity. If the rigidity is not enough, it should be reinforced. (3) The inclination of the belt conveyor should not be too large to avoid large errors caused by the rolling of the material on the belt. Generally, the inclination angle must be less than 20°. When the belt has inclined and horizontal sections, try to install the scale in the horizontal section. (4) In order to ensure the normal fit of the belt and the weighing roller, so that the weight of the material is faithfully transmitted to the weighing roller, the scale should be installed at the position where the tension of the conveyor belt and its change are the smallest. (5) In order to ensure the minimum pressure change of the belt symmetrical heavy roller, the weighing section idler should be carefully adjusted so that the rollers are parallel to each other and in a plane. (6) For the grooved idler set, the belt must be in uniform contact with the three idlers, and there should be no gap between the belt and the bottom idler. (7) In order to reduce the change of belt tension, the belt conveyor should have only one fixed blanking point, and a height adjusting plate should be installed at the feeding opening to make the material on the belt even. Fourth, regular physical calibration In order to ensure the dynamic measurement accuracy of the electronic belt scale system, the key measure is to frequently perform calibration. (1) Whether the belt has deviation, breakage, whether the roller is stuck with material, whether the sensor has displacement and buried by the accumulated material. (2) Whether the meter switch is in the normal position and whether the meter indicates normal. (3) Whether the power supply voltage is too high or too low. (4) If the above conditions are normal, the counter should skip the word and the speed is normal. (5) If there is any abnormality in the position of each switch, it should be stopped for inspection and troubleshooting. Fifth, do a good job of maintenance To ensure the accuracy of the electronic belt scale, the maintenance work must be done carefully. In use, the following points are required. (1) Frequently remove the dust from the control display to prevent static damage to the components; clean the scale frame in time to prevent the scale from being damp, dust, moisture and rust cause the friction of the roller to affect the belt tension, resulting in changes in measurement accuracy. (2) Strictly prevent the human body or overweight objects from pressing on the weighing section to prevent the sensor from overloading and causing errors. (3), metal clips can not be used at the belt joints, must be glued, smooth and smooth, to meet the standard requirements of the belt. If the belt is found to be damaged or deteriorated, repair and replace the belt in time. (4) The conveying capacity of the belt conveyor should be lower than the rated value of the electronic belt scale. (5) The operation management personnel should master the standards and specifications of the electronic belt scales, establish and strictly implement the operation system, and analyze and eliminate the relevant faults in time.
