Advantages of Propane Diaphragm Compressors
01
Absolutely Oil-Free and Ultra-High Gas Purity
The diaphragm completely isolates the hydraulic oil from the compressed gas, ensuring 100% oil-free contamination of the propane medium during the compression process. This is critical for applications such as polymer-grade propane, food-grade propane, or specialty gas filling, safeguarding product quality and safety in downstream processes.
02
Zero Leakage and Intrinsic Safety via Static Sealing
The entire gas compression chamber adopts a static sealing structure, fundamentally eliminating process leakage. Combined with a three-layer diaphragm safety design and a rupture alarm system, it provides the highest level of intrinsically safe protection for compressing flammable and explosive propane, making it especially suitable for installation in safety-sensitive areas or for handling valuable gases.
Key Design Points for Propane Diaphragm Compressors
Diaphragm and Material Compatibility Design
To address the swelling effect of hydrocarbon gases like propane on certain rubber or polymer materials, metal diaphragms and sealing materials with excellent compatibility must be selected. Flow-wetted components such as the cylinder head and gas valves should also be preferentially made of 316L stainless steel to meet both corrosion resistance and swelling resistance requirements.
Precise Thermal Control and Anti-Liquefaction Monitoring
Based on propane's near-ambient critical temperature characteristics, accurate thermodynamic calculations must be performed to design efficient diaphragm chamber cooling channels. The control system must integrate high-high discharge temperature alarms and interlock shutdown functions to ensure the operating temperature always remains above the dew point temperature at the operating pressure, with a sufficient safety margin, to strictly prevent liquid formation.
Integrated Safety and Purging System
The compressor body shall be integrated with combustible gas detector connection ports. Safety valves must be provided, with a relief capacity greater than the maximum compressor discharge capacity, and the discharge port shall be routed to a flare or a safe area. In addition, nitrogen purging interfaces shall be reserved for thoroughly displacing air from the piping and compression chamber before startup to prevent the formation of explosive mixtures.
