Operating conditions of spoke type load cell in concrete mixing plant
A big difference from the electronic scales commonly used for business measurement is that the spoke type load cell in the concrete mixing plant station is in quite harsh operating conditions, the stress environment is very complicated, and the operating environment of general electronic products. Compared to, there is greater randomness. Here are four conditions for you to run:
1. Artificial Environment The human environment is one of the factors that must be considered when designing product reliability. Concrete mixing buildings are generally installed at the construction site. Temporary workers are heavily used on the construction site, and a considerable number of temporary workers have low levels of literacy and lack the necessary skills. In the maintenance and cleaning of equipment, it is very likely that the sensor is subjected to sputtering of high-pressure water, and overload caused by misoperation. Obviously, the sensor must be designed in such a long-term and reliable environment under such environmental conditions.
The above basic requirements and operating conditions can be used as the basis for the selection of load cells for concrete mixing plants (stations).
2. Ambient temperature and humidity The concrete mixing plant is usually installed in the open air. The spoke type load cell may be exposed to the sun and rain, and the temperature changes drastically. Many engineering projects are in mountainous or remote areas where natural conditions are rather harsh. Therefore, a greater temperature range and higher humidity conditions must be considered. Concrete requires water during the production process. In the process of water transportation and weighing, a lot of water vapor is also generated, and a relatively humid environment is formed in a certain small range. In the temperature-controlled mixing building, there are different requirements for high temperature conditions and low temperature conditions. In the summer, when running in low temperature conditions, it is necessary to pass cold air below zero and stir with ice. At this time, condensation will appear in the building, which shows the high humidity in the building.
3. Impact and vibration During the feeding process, the sand and gravel will have an impact. The sensor should be able to withstand an acceleration of 5g. During the agitation process, continuous vibration is generated, and the vibration generates fatigue damage.
4. Dust concrete requires a large amount of cement, coal ash and an appropriate amount of admixture in the production process. These powders produce dust during transport and weighing. Even in aggregates, dust is generated during transportation. Some of these dusts will adhere to the sensor surface. Under the combined action of dust and moisture, the sensor will be subject to more severe corrosion.
Therefore, the damage of the powder scale sensor is usually more frequent than the sensors of other scales.
