In flammable and explosive scenarios such as chemicals, oil and gas, pharmaceuticals, explosion-proof weighbridges are essential equipment, but the quality of explosion-proof weighbridges in the market is uneven. Xuzhou Speyer has compiled a pit avoidance guide for the purchase of explosion-proof weighbridges, and the four core certifications and configurations are indispensable.
1. The explosion-proof certification must be complete and meet the scene level
For example, in the explosive gas environment of the chemical industry, it is necessary to choose the Exib II BT4 level of the scale, and the dust explosion environment must match the dust explosion-proof certification of DIP A21 TA and T6.
2. The core components need to be explosion-proof, and eliminate "pseudo-explosion-proof"
Some manufacturers only do explosion-proof treatment for weighing instruments, and the sensor and junction box are still ordinary configurations, which belong to "pseudo-explosion-proof" equipment. Qualified explosion-proof weighbridges, all electrical components such as sensors, junction boxes, instruments, and power cables need to be explosion-proof, and adopt explosion-proof or intrinsically safe design to ensure that no electrical sparks will be generated when any component failure occurs, eliminating potential safety hazards from the source.
3. It has anti-corrosion and sealing properties, and is suitable for complex chemical environments
The chemical industry not only has the need for explosion-proof, but also has the problem of corrosive media eroding equipment. Therefore, the explosion-proof weighbridge needs to use stainless steel core components, the scale body is corrosion-resistant spraying, and all interfaces should be sealed to prevent corrosive gases and liquids from entering the equipment, which not only meets the explosion-proof requirements, but also adapts to the corrosion challenges of the chemical environment.
4. Support data linkage, taking into account security and management efficiency
The explosion-proof weighbridge of chemical enterprises can not only meet safety needs, but also need to be linked with the workshop production system. High-quality explosion-proof weighbridges can be equipped with explosion-proof data transmission interfaces, which automatically synchronize the weighing data to the batching system or storage system of chemical enterprises, without manual transfer of data, which not only avoids the stay time of personnel in the explosion-proof area, but also improves the efficiency of production management.
The full range of explosion-proof weighbridges of Xuzhou Speyer has passed the national explosion-proof certification, and can customize exclusive solutions according to different chemical scenarios to ensure both safety and efficiency.
