Safety Distance Specification and Implementation Points of Air Compressor and Surrounding Workshops
as the core equipment in industrial production, the installation layout of air compressor should strictly follow the safety distance specification to ensure the stable operation of equipment, safe operation of personnel and reduce potential risks. According to industry standards and enterprise practice, the safety distance requirements and implementation points of air compressor and surrounding workshops are as follows:
1. Core Safety Distance Standard
- spacing between air compressor and wall
- basic requirements: A spacing of at least 70cm should be reserved between the air compressor and the wall. This space is mainly used to ensure equipment heat dissipation, daily maintenance and pipeline connection operations.
- Analogy Description: Like "Reserving breathing passages for air compressors" to avoid overheating or maintenance difficulties due to wall obstruction.
- Specification for Arrangement of Gas Storage Tank
- outdoor Priority Principle: Gas storage tanks (especially those with oil content> 1 mg/m & sup3;) should be preferentially arranged outdoors and located on the north side of the machine room to reduce sunlight and reduce the risk of explosion.
- Indoor layout conditions if indoor installation is required due to site restrictions, the clear distance between the gas tank and the outer wall shall not be less than 1 m, and ventilation and lighting shall not be affected.
- Risk warning: The gas storage tank is similar to a "pressure cooker" and should be kept away from high temperature sources and confined spaces to avoid overpressure explosion.
- Channel width requirements
- dynamic adjustment principle: The width of the channel shall be determined according to the displacement of the air compressor, ranging from 0.8 m to 1.5 m.
- Small air compressor (displacement <20m & sup3;/min): Channel width ≥ 0.8 m.
- Large air compressor (displacement ≥ 20m & sup3;/min): Channel width ≥ 1.5 m.
- functional analogy: The passage is like an "equipment corridor", which shall meet the requirements of equipment transportation, personnel inspection and emergency evacuation.
2. environmental risk prevention and control measures
- thermal and ventilation management
- high temperature equipment isolation: The air compressor should be away from the furnace, oven and other high-temperature equipment to avoid inhaling high-temperature air and causing the exhaust temperature to be too high.
- Confined space ventilation: If installed indoors, exhaust equipment must be installed, and the exhaust air volume must be greater than the air volume of the air compressor cooling fan to prevent hot air circulation.
- Figurative Description: Like "Equipping air compressor with independent air conditioner", ensure that its operating environment temperature is ≤ 40 ℃.
- fire and explosion-proof design
- risk classification of gas storage tank:
- high risk tank (oil content> 1 mg/m & sup3;): Forced outdoor layout, and install explosion-proof valve and pressure alarm device.
- Low risk tank (oil content ≤ 1 mg/m & sup3;) an independent exhaust system shall be added for indoor layout, with air changes ≥ 3 times per hour.
- Fire protection support: The engine room needs to be equipped with carbon dioxide fire extinguishers, and the manual switch is set outside the dangerous area.
- Hazardous substance isolation
- division of hazardous areas: The air compressor room should be far away from the spray booth, chemical warehouse and other places to avoid corrosive gas or dust entering the equipment.
- Protection level: If it is not possible to avoid harmful substances in the vicinity, a pre-filter device should be installed to ensure that the air cleanliness meets the ISO 8573-1 standard.
3. Implementation Points and Suggestions
- layout planning stage
- reserved expansion space: The design of the computer room shall consider the demand for future equipment expansion, and at least 1 meter of room for expansion shall be reserved around.
- three-dimensional space utilization: The top of the air compressor shall be kept at least 1 m to avoid affecting heat dissipation and hoisting operations.
- Routine maintenance management
- regular inspection check the channel smoothness every week and clean up the sundries to ensure that the safe distance is not occupied.
- Environmental monitoring: Install temperature and humidity sensors, monitor the environment of the computer room in real time, and automatically start the exhaust system when the temperature is over.
- Formulation of emergency plan
- explosive Disposal gas leakage alarm device shall be set in the gas storage tank area and linked with the exhaust system.
- Personnel training operators should be familiar with the safety distance requirements, and master the emergency evacuation route and the use of fire fighting equipment.
4. Summary
the safety distance between the air compressor and the surrounding workshop needs to consider the equipment characteristics, environmental risks and operation requirements. Through the strict implementation of wall spacing, gas tank layout and channel width standards, and supporting heat dissipation, fire prevention and harmful substance isolation measures, can effectively reduce the equipment failure rate and safety accident risk. Enterprises should incorporate the safety distance requirements into the equipment management system, ensure the standard landing through regular inspection and training, and provide a solid guarantee for safe production.
