How to minimize the amplitude of the zero drift of the electronic belt?
- 2019-05-15-

The stability of the zero point of the electronic belt directly affects the accuracy of the weighing to the guessing. However, the zero drift of the electronic belt scale in actual use is a common phenomenon. How to reduce the amplitude of the zero drift as much as possible? Several measures are available for our reference.

First of all, of course, it is necessary to find out the cause of the zero drift of the electronic belt scale during the weighing process. Generally, the small-scale zero drift is a normal phenomenon, which can be adjusted through intensive maintenance and often zero calibration, and the large zero drift is If you are not normal, you should investigate the problem.

In fact, the main faults in this area are caused by two major parts, mechanical and electronic. At the same time, attention should also be paid to the influence of interference during weighing. The mechanical primary view of the force of the scale body equipment and the weighing roller, the quality of the equipment is critical to the stability of the zero point of the electronic belt scale.

Therefore, in the equipment, the primary scale body should be reasonably resistant to interference, and there should be no uncertain external force acting on the scale. And in normal use, pay attention to the weighing roller to be freely stressed, no material can be stuck between the weighing roller and the stringer, if it is necessary to eradicate in time.

The electronic part of the electronic belt scale for weighing and feeding is mainly due to the appearance and the sensor. The overload or damage of the sensor may cause the inaccuracy of the AD value, causing the drift of the zero point. If this is the case, the sensor is loaded multiple times. For objects of the same weight, investigate whether the AD value of the sensor output is consistent and normal.

If the above reasons have been cleaned, but the zero drift of the electronic belt scale is still too large, then only reduce the speed of the belt conveyor as much as possible, increase the weight of the material per meter on the belt, so that the accuracy of the forward weighing measurement The sexual effect is very significant.

If the weighing material of the biomass material is also selected as the electronic belt scale, since the density of the material is relatively small, the same bandwidth flow rate is much smaller, which causes the weight change to be insignificant, and the sewage treatment equipment increases the metering. The negligence, the special zero point has a significant impact on the metering effect.

In order to solve this problem, on the one hand, it is necessary to lower the speed of the belt conveyor, and the slower the better, the more accurate the metering is. On the other hand, it is necessary to increase the amount of transportation, and as far as possible, the amount of transportation should be advanced and the belt speed should be lowered. Others can often perform zero calibration to reduce the impact of zero-point negligence on the metering effect.
