Talk about how to calibrate the weight loss feeder?
Loss-in-weight feeders are the main equipment in BATTE manufacturing. A loss-in-weight feeder is not a simple scale. So what's the difference between the weight loss scales? Loss-in-weight scales consist of a variety of devices, such as agitators, load cells, etc.
After entering the calibration screen, start calibrating the high precision weightless scale. First, place a weight larger than 85% of the load cell's capacity on the weightless scale body, and then enter the corresponding weight in the weight input box. Then, click the Calibrate button. At this point, the real-time weight will be displayed as the weight value placed on the scale body. Then record the calibration factor value. Then, place the weights of 60%, 40%, 20% and 10% of the capacity of the load cell on the scale body respectively, and observe whether the value displayed by the real-time weight is consistent with the weight of the weight placed on the scale body. If they match, the calibration is correct. If the inconsistency indicates incorrect calibration, recalibration is required.
The following describes the use of each part from the use of the loss-in-weight feeder. The frame of the continuous gravimetric feeder is the overall support force, and the connection and support of all parts of the machine are completed by it. The material needs to pass through the feed valve before feeding. For the type of valve, ball valve, butterfly valve, gate valve, etc. are widely used. The performance of the equipment is mainly considered from the aspects of whether it can be sealed, whether the switch is flexible, and whether the feeding is fast and smooth. The weighed material is transported by the weighing hopper. In the case of weighing, it is necessary to consider whether they are resistant to corrosion and acids, i.e. corrosion and acid resistance.
Weightless scales have certain requirements on materials during use. The simplest point is good liquidity. For poorly flowing materials, use an agitator. It can help materials with poor fluidity to complete unloading. The above steps complete the steps of loading and processing the material. How should the unloading of the weightless scale be operated? Depending on the material, the unloading device will be different and the usage environment will also be different, so there will be screw and belt feeders.;
In summary, the above is to talk about the main content of how to calibrate the weightless scale. Standard error is the key to ensure the accuracy of test results and the reliability of measured values. The standard for the static test of the weightless scale is the standard weight, and the main standard for the dynamic test is the control weight of the standard weight used for the test, provided that these standard weights are calibrated or verified immediately before the type evaluation test, the error of the standard weight It shall not be greater than 1/3 of the maximum allowable MPE of the weightless scale under test. email@example.com
