Weighing sensors should be handled lightly, especially small-capacity sensors made of aluminum alloy elastomers, any impact, drop, its measurement performance may cause great damage. For large-capacity load cells, in general, it has a large self-weight, so it is required to use appropriate lifting equipment (such as chain hoists, electric hoists, etc.) as much as possible during handling and installation.
The base mounting surface on which the sensor is mounted should be flat and clean, without any oil film, glue film, etc. The mounting base itself should have sufficient strength and rigidity, generally higher than the strength and rigidity of the sensor itself.
Level adjustment: Level adjustment has two aspects. First, the mounting plane of a single sensor mounting base should be leveled with a spirit level. On the other hand, the mounting surface of multiple sensor mounting bases should be adjusted to a horizontal plane (quasi-geometry) as far as possible, especially when the number of sensors is more than three. We should pay more attention to this point in the weighing system. The main purpose of this is to make the load on each sensor basically consistent.
The loading direction of each load cell is determined, and when we use it, we must load the load in this direction. Lateral forces, additional bending moments, and torque forces should be avoided as much as possible.
Use structural components with automatic positioning (reset) as much as possible, such as ball bearings, joint bearings, and positioning fasteners. They can prevent some lateral forces from acting on the sensor. It should be noted that some lateral forces are not caused by mechanical installations, such as lateral forces due to thermal expansion, lateral forces due to wind, and lateral forces caused by the vibration of agitators on certain vessel-type instruments. .
Some scales must have accessories attached to the scale body (such as conveyor scales for container scales, etc.), and we should allow them to be as soft as possible in the direction of the sensor loading the main shaft to prevent them from “eating†the true load of the sensor. Together, it causes errors.
Some “baffles†should be set around the load cell and even covered with a thin metal plate. This prevents impurities from contaminating the sensor and some moving parts. This “staining†tends to make the movable part uncomfortable and affect the weighing accuracy.
Tungsten carbide welding rope is a type of welding filler material that is used for hardfacing applications. It is made by combining tungsten carbide particles with a binding material, such as nickel or cobalt, to create a rope-like form.
Tungsten carbide is known for its exceptional hardness and wear resistance, making it ideal for applications where the welded surface needs to withstand extreme abrasion and impact. The welding rope is typically used in industries such as mining, oil and gas, construction, and agriculture.
When the tungsten carbide welding rope is heated during the welding process, the binding material melts and fuses the tungsten carbide particles to the base metal, creating a hard and durable surface. This helps to extend the lifespan of equipment and machinery by protecting it from wear and tear.
Tungsten carbide welding rope can be applied using various welding processes, including manual metal arc welding (MMA), gas tungsten arc welding (GTAW), and flux-cored arc welding (FCAW). The choice of welding process depends on the specific application and the equipment available.
Overall, tungsten carbide welding rope offers a cost-effective solution for protecting and repairing high-wear surfaces, making it a popular choice in industries where durability and longevity are essential.
