Matters needing attention when repairing online checkweigher.
Online checkweigher machine is a testing instrument that uses the force of an object to determine the quality (net weight) of an object. It can also be used to clarify other quantities, main parameters or characteristics related to quality. It is the mechanical equipment and force transmission calibration system software between the weighing object and the transforming component (also called the scale body of the electronic scale). It generally includes the medium to receive the load of the weighing object, the bridge structure, and the suspension. Connecting components, ultimate shock absorption organization, etc. Online automatic checkweigher machine. The basic requirements of the online automatic checkweigher machine for the sensor are: the power and the entered net weight maintain a single value, the linear correlation is good, the sensitivity is high, the harm to the weighed object is small, the standard deviation in the work, the phase frequency characteristics Good, stable and reliable. Detailed introduction of common problems of online automatic checkweigher maintenance: 1. The scale of the case’s business scale is 1/3000~1/50000, and its sensitivity is very high. Therefore, a good application level must be selected. The national legal assessment level is 1 /3000. The applied sensor should be C3 level. 2. The left and right support frames of the sensor must be installed accurately and timely. 3. The sensor of the scale is small in volume and small in size, so the force should be light when disassembling, and the sensor should be well maintained. 4. The scales in some special cases have unique structures to ensure regulations. The sealant cover should be well packed, and the main circuit board should be coated with waterproof glue or silica gel. 5. Some unique common faults, such as abnormal display information, automatic code jump, etc. , May be caused by simple reasons, such as battery voltage drop, the dial rubbing on the case, etc. , So be careful when checking. The online automatic checkweigher has upgraded the sound alarm module for the electronic scale. When the customer puts the goods that exceed the load of the electronic scale on the electronic scale, it will give an audible reminder. Nowadays, the customer's rest weight is beyond the detection range, and an alarm with a different color tone was sent out to remind the customer. This product is a measuring instrument, and laymen cannot disassemble it casually. If there is an abnormal situation, when everything cannot be used normally, be sure to report for inspection and repair immediately, and regular inspections and repairs by technical professional staff. There is no need to disassemble and assemble parts independently.
