Safety Regulations and Precautions

As a pressure vessel, the pressure tank must strictly adhere to safety operation regulations to prevent accidents caused by pressure loss of control or material leakage:

1. Pressure Safety: Overpressure operation is strictly prohibited (the internal pressure must not exceed the design pressure). Regular pressure vessel inspections must be conducted (once every 3 years).
2. 
   
3. Anti-static Measures: The tank must be reliably grounded (grounding resistance ≤4Ω). When conveying flammable or explosive materials (such as bituminous coal), nitrogen must be used as the fluidizing gas (inert protection).
4. Operation Standards: Strictly follow the "loading - pressurization - conveying - pipeline clearing" process. It is forbidden to open the feed valve or manhole under pressurized conditions.
5. Emergency Response: In case of tank leakage, immediately shut down and depressurize, purge and dilute the material with inert gas. Direct water flushing is strictly prohibited (to avoid agglomeration and clogging).
6. 
   

Summary

The pressure tank is the core equipment of the positive pressure pneumatic conveying system, and its performance directly determines the efficiency, stability, and safety of material transportation. During selection, it is necessary to prioritize the appropriate type of pressure tank based on material characteristics, conveying distance, and flow requirements (e.g., dense phase pressure tanks for long distances, dual-tank systems for continuous conveying). In daily operations, it is essential to closely monitor pressure and fluidization parameters and promptly address issues such as blockages and leaks. With the advancement of intelligent technology, future pressure tanks will gradually achieve integrated management features such as "automatic cycle control, fault warning and diagnosis, and energy consumption optimization," further enhancing the economy and reliability of industrial material transportation.
