As an accurate, convenient and fast load bearing measuring equipment, electronic platform has been purchased and used more and more in recent years with the rapid development of market economy. However, in actual work, the author found that it may be because the electronic platform scales purchased by some enterprises are poor in material or performance, or because some enterprises do not understand the classification, structure and performance of electronic platform scales, or their behavior in the process of installation and use is not standardized, which caused the improper use of electronic platform scales and caused some unnecessary economic losses to enterprises. Now let's have a look with the manufacturer of - weighbridge:
3. Operating principle of electronic platform scale
The working principle of the electronic platform scale: first place the object to be weighed on the panel of the carrier, then output the corresponding electrical signal from the load bearing sensor at the bottom of the carrier according to the actual situation and transmit it to the display instrument of the electronic platform scale, and finally display the weighing result through the data calculation inside the display instrument.
4. Typical problems and solutions of some enterprises in the process of using electronic platform scales
(1) Problems caused by errors in the installation of electronic platform scales and solutions
(1) Phenomenon of the problem
In the actual work, the author found that many enterprises installed the bearing body of the electronic platform scale in the prefabricated trench in order to facilitate the use of the weighing process. However, some of them simply used the process of tamping and leveling with cement when building the trench, which caused the phenomenon of random drift of the display value of the electronic platform scale when weighing heavy goods.
(2) Analyze the cause of the problem
That is to say, some enterprises did not reinforce the ground of the supporting parts of the bearing body, which caused the inclination of the horizontal position of the bearing body when weighing heavy weights, and even caused the suspension of individual supporting points.
(3) Solution:
At this time, the author suggests that the enterprise should rebuild the cement trench of the bearing body and reinforce it at an appropriate location (by installing embedded steel bars or iron plates) to solve the problem.
(2) Problems and solutions caused by improper use of electronic platform scales
(1) Problem phenomenon
In actual work, the author found that a small number of enterprises in wire drawing, wire and cable industries may be to control production costs, or to facilitate the measurement and control of quality control points in a specific production link, so as to buy and use a large number of electronic platforms. However, the author found that enterprises often reported that some electronic platforms said that after 1 to 2 years of normal use, and often within a short period of time after normal inspection, there would be frequent errors in the display value of the display instrument.
(2) Analyze the cause of the problem
After careful observation and research on the emerging electronic platform scale, the author found that they have a common feature for the internal production process of wire drawing, wire, cable and other industries. That is, these enterprises often need to measure and weigh "spool like objects" in the production link. However, the author first found that individual front-line workers often roll the "spool like objects" onto the carrier of the electronic platform scale by rolling on the ground or lifting with a crane in the actual weighing work. Secondly, the author found that at this time, the contact area between the "bobbin like objects" and the surface of the bearing body is often small, and the "bobbin like objects" are often of large mass. In addition, the most critical point is that the panel of the bearing body called by some electronic platforms is thin and there is no reinforced steel beam installed. Therefore, after long-term use by enterprises, It will cause the iron plate on the surface of the bearing body of the electronic platform to appear "fixed point stress" deformation under specific circumstances. As a result, the display value of the display instrument frequently appears error.
(3) Solution
In this case, the author first suggests that enterprises eliminate the electronic platform scale and replace it with an electronic hook scale in the production process. Secondly, if the enterprise is unable to replace the special electronic hook scale in a short time due to some reasons, and still needs to continue to use the electronic platform scale, the author can only suggest that the enterprise add a thicker steel plate on the surface of the bearing body of the electronic platform scale to solve the problem. However, after a long period of practical work, the author found that more than 99% of electronic platforms said that they could recover "health!" and continue to use "healthy and long-term" after being covered with steel plates.
5. Concluding remarks
First of all, in terms of the installation and use of the electronic platform, some typical errors inadvertently have brought some unnecessary economic losses to some related enterprises. From this point of view, we should pay high attention. Secondly, the author hopes that the above work experience can become an effective way for some enterprises to solve relevant problems.
