Why are diaphragm compressors ideal for compressing gas mixtures?
Diaphragm compressors feature static seals with metal diaphragms that provide a 100% leak-free environment. This guarantees that different components in a gas mixture do not leak into the surroundings, and prevents external air or lubricating oil from contaminating the mixture, maintaining the exact ratio and purity of the gases.
How is explosion protection managed for hazardous gas mixtures?
The electrical systems and explosion-proof equipment are rated based on the most hazardous component in the gas mixture (the one with the lowest auto-ignition temperature and highest gas group). In addition, integrated combustible gas detectors monitor the ambient environment and interlock with emergency ventilation systems to mitigate risks.
What materials are used for wetted parts to resist corrosion?
Depending on the chemical reactivity and corrosiveness of the specific gas mixture, wetted components like the diaphragm head cavity and the diaphragms themselves are custom-fabricated from high-durability alloys, such as 316L stainless steel or Hastelloy.
What happens if a diaphragm ruptures during operation?
A built-in multi-layer diaphragm rupture monitoring system is standard. If any diaphragm layer fails, the pressure sensor immediately detects the change, triggers an alarm, and shuts down the compressor. This prevents process gas from entering the oil system and keeps oil out of the gas stream.
Why is nitrogen purging necessary for these systems?
Nitrogen purging is used during pre-startup to clear out oxygen and air that could create explosive mixtures when mixed with flammable process gases. Post-shutdown purging ensures no hazardous gas remains trapped inside the compressor heads, facilitating safe maintenance and pressure holding.
How do I choose the correct compressor model (GZ, GV, GL, GD) for my project?
Model selection depends primarily on your required flow rate, inlet/outlet pressures, and motor power constraints. GZ and GV models are generally suited for lower flow ranges (up to 200–500 Nm³/h), while GL and GD models handle high-capacity requirements up to 2000 Nm³/h with power ratings up to 200 kW.
