The Explosion-Proof Weight Filling Machine is specially designed for safely and precisely filling flammable or volatile liquid products. Built with an anti-explosion electrical system, it ensures secure operation in hazardous environments while maintaining exceptional filling accuracy.
This above-surface filling system allows the operator to easily position the drum under the filling nozzle. Once the start button is pressed, the machine automatically tares the weight and performs a two-speed filling process—fast for bulk flow and slow for precision. Upon completion, the filling valve automatically retracts, and a drip collection system prevents product leakage, ensuring a clean and efficient workflow.
Ideal for chemical, petrochemical, coating, and solvent industries, this explosion-proof liquid filling machine offers a combination of safety, reliability, and high-speed performance, making it an essential solution for modern hazardous-area liquid packaging.
Explosion Proof Weight Filling Machines Features
1. Advanced Explosion-Proof Control System
Built with explosion-proof protection, this weight filling system is designed for safe operation in hazardous environments. Every electrical component meets strict explosion-proof standards, ensuring reliability and operator safety in volatile conditions.
2.High-Speed & High-Precision Weighing
The system features a 200 times/sec A/D conversion rate and an internal resolution of 1/1,000,000, providing rapid and ultra-precise weighing feedback. Combined with a 1/60,000 display resolution, it guarantees accuracy even in dynamic industrial environments.
3.Intelligent Dual-Display Interface
Equipped with a dual-display panel, the system simultaneously shows real-time weight, target fill, and operational data. The LED screen with status indicators gives operators clear visibility for efficient monitoring and control.
4.Smart Filling Control & Anti-Vibration Software
The explosion-proof liquid filling controller incorporates dynamic and static anti-tremble algorithms, along with refined feeding and pre-compensation modes. These ensure stable operation, even under vibration or pressure fluctuation.
5.Multi-Stage Filling Accuracy Optimization
The system uses slow feeding with frequency and amplitude correction, improving filling precision and minimizing product loss. The automatic tare removal function ensures consistent accuracy across multiple batches.
6.Data Management & Traceability
Capable of storing up to 30 preset filling recipes, the system supports auto printing, batch accumulation printing, and formula printing. Operators can easily recall settings, track performance, and maintain production traceability.
