Industry And Precautions for Using Oil-free Piston SF6 Compressors

Industry and precautions for using oil-free piston SF6 compressors

Industry of using oil-free piston sulfur hexafluoride (SF6) compressors

Oil free piston sulfur hexafluoride compressors have important applications in the following industries due to their oil-free design and high-purity gas processing capabilities:

1. Electricity and transmission and distribution industry

High voltage equipment manufacturing: used for the production of SF6 circuit breakers, gas insulated switchgear (GIS), high-voltage transformers, and transmission pipelines, utilizing the high insulation and arc extinguishing performance of SF6 to enhance equipment safety.

Gas recovery and treatment: In SF6 insulation equipment maintenance, compressors are used to recover and purify gases, reducing greenhouse gas emissions.

1. Medical and scientific research fields

In medical equipment: such as X-ray machines, laser machines, etc. that require high-purity inert gas, SF6 compressors provide a clean gas source.

Laboratory application: used for tracer analysis and inert gas environment construction.

2. Microelectronics and Semiconductor Manufacturing

Electronic etching: Electronic grade high-purity SF6 is used as an etchant for the manufacturing of chips and precision electronic components.

4. Metallurgical and chemical industries

Metal smelting protection: In the magnesium alloy melting furnace, SF6 serves as a protective gas to prevent oxidation, and the compressor ensures stable gas supply.

Chemical production: used for inert gas protection reactions and manufacturing of new fire extinguishers.

5.Mining and Tunnel Engineering

Mine safety: SF6 serves as an anti adsorbent to replace oxygen in the mine, reducing the risk of coal dust explosion.

6.Refrigeration and freezing industry

Low temperature refrigeration: SF6 compressor provides efficient refrigerant circulation in refrigeration systems ranging from -45 ℃ to 0 ℃.

Precautions for use

1. Installation and environmental requirements

Ventilation and Cleanliness: Avoid installation in damp, dusty, or flammable/explosive environments, ensure good ventilation to prevent gas leaks or equipment overheating

Fixed and shock-absorbing: It needs to be securely installed and equipped with shock-absorbing devices to prevent vibration from causing pipeline loosening or gas leakage.

2. Operating standards

Pressure control: It is strictly prohibited to operate under overpressure (usually with a maximum pressure of 8 bar). Regularly check the safety valve and pressure gauge to prevent the explosion of the gas storage tank.

3. Gas management

Leak prevention measures: SF6 is a potent greenhouse gas (with a greenhouse effect 22200 times that of CO ₂), and regular inspections of pipeline sealing are required. Gas recovery devices should be equipped to reduce emissions.

Do not mix gases: only for handling SF6 gas, not for other gases or liquids, to avoid chemical reactions or explosion risks.

4. Maintenance and Inspection

Regular maintenance: Clean the filter element and check the seals every quarter, replace key components (such as air valves) every year to ensure compressor efficiency and gas purity.

Emergency stop: Stop immediately upon discovering air leakage, abnormal noise, or abnormal temperature, and restart after troubleshooting.

5. Safety protection

Operator training: Professional training is required before operation, familiar with emergency handling procedures (such as leak emergency measures).

Anti electric shock and explosion prevention: Keep away from grounding conductors, prohibit non staff from approaching, and avoid accidents caused by static electricity or sparks.
