How to ensure the safety of the air compressor in the use environment?

To ensure the safety of the air compressor in the use environment, it is necessary environmental adaptability, equipment protection, operation specification, maintenance and emergency management five dimensions of comprehensive policy, covering the installation, operation, maintenance of the whole life cycle. The following are specific measures and technical points:

1. Environment Adaptability: Selecting and Transforming Safe Use Scenarios

1. ventilation and heat dissipation
   • installation position the air compressor should be placed in a well-ventilated independent machine room or open area to avoid heat accumulation in confined spaces (such as basements and narrow warehouses).
   • Heat dissipation channel: Ensure that the air inlet and exhaust port are not blocked, and keep a distance of at least 1 meter from the wall and other equipment to prevent hot air from returning.
   • forced ventilation in high temperature environment (such as summer workshop), exhaust fan or air conditioner shall be installed to control the temperature of the machine room ≤ 40 ℃ to avoid high temperature deterioration of lubricating oil or failure of electrical components.
2. Dust-proof and moisture-proof
   • filtration device: Install multi-stage air filters (such as primary, medium and high-efficiency filters) at the air inlet to intercept dust and particles and prevent wear parts from entering the compression chamber.
   • Moisture-proof measures: Moisture-proof mat shall be laid on the ground of the machine room, and waterproof coating shall be applied on the wall; Dehumidifier shall be provided in humid areas (such as coastal areas and underground areas) to keep the relative humidity ≤ 70% to avoid short circuit of electrical components or corrosion of metal parts.
3. Anti-corrosion and explosion-proof
   • corrosive environment in the chemical industry, electroplating and other places, the use of corrosion-resistant coating air compressor (such as stainless steel), or the room for anti-corrosion treatment (such as epoxy resin coating).
   • Explosion-proof requirements flammable and explosive places (such as gas stations and paint spraying rooms) need to use explosion-proof air compressors (in line with Ex d IIB T4 standard), and be equipped with explosion-proof electrical components and electrostatic grounding devices.

2. equipment protection: security reinforcement at the hardware level

1. mechanical safety protection
   • transmission component isolation: Install protective covers for rotating parts such as pulleys and couplings to prevent injuries caused by personnel contact.
   • Pressure Vessel Safety the gas tank and pressure pipeline shall be inspected regularly (once a year), and safety valve (set pressure ≤ 1.05 times of design pressure) and pressure gauge (accuracy ≥ 1.5) shall be installed to ensure automatic pressure relief in case of overpressure.
2. Electrical safety protection
   • earthing and leakage protection: The air compressor shell is reliably grounded (grounding resistance ≤ 4Ω), and the distribution box is equipped with leakage protector (operating current ≤ 30mA, operating time ≤ 0.1s).
   • Insulation monitoring: Regularly check the insulation performance of the motor and cable (insulation resistance ≥ 0.5 MΩ) to avoid electric shock or fire caused by leakage.
3. Temperature and vibration monitoring
   • temperature sensor: Install temperature sensors in key parts such as bearings, motors, exhaust ports, etc., to monitor the temperature in real time (such as bearing temperature ≤ 80 ℃), and give an alarm when the limit is exceeded.
   • vibration analysis: Monitor the vibration value of the equipment through the vibration sensor (such as ISO 10816 standard), and find the rotor imbalance, bearing wear and other faults at an early stage.

3. Operation Specification: Safety Constraints of Personnel Behavior

1. operator Qualification
   • training and induction: operators need to master the equipment structure, principle, operation process and emergency treatment through professional training (such as training courses provided by air compressor manufacturers).
   • Permit operation: special operation certificate (such as electrician certificate and explosion-proof electrical operation certificate) shall be obtained for operation in explosion-proof places.
2. Standardized operation process
   • pre-startup inspection confirm that the oil level, pressure gauge, safety valve and protective device are normal, and drain the condensed water.
   • Monitoring in operation: Record pressure, temperature, vibration and other parameters every 2 hours. Overpressure and overtemperature operation are strictly prohibited.
   • Maintenance after shutdown: After turning off the power, wait for the equipment to cool down (≥ 15 minutes), and then perform maintenance such as cleaning and lubrication.
3. Prohibited Acts
   • it is forbidden to disassemble pipes or valves under pressure;
   • it is forbidden to touch the rotating parts when the equipment is running;
   • it is forbidden to use open flame or flammable materials near the air compressor.

4. maintenance: preventive maintenance reduces risk

1. regular maintenance plan
   • routine maintenance: Clean the surface of the equipment daily, check the oil level and pressure gauge; drain the condensed water of the gas tank every week; check the belt tension and electrical connection every month.
   • Regular maintenance replace the air filter element and oil filter element every 500 hours; replace the lubricating oil (such as fully synthetic air compressor oil) every 2000 hours; overhaul every 4000 hours to check the wear of the rotor and bearing.
2. Critical Component Life Management
   • safety valve: Check once a year to ensure the accuracy of the jump pressure;
   • pressure gauge: Check once every half a year, with error ≤ ± 1.6%;
   • belt: Replace it every 2 years to avoid equipment downtime due to breakage.
3. Lubricant management
   • oil selection according to the type of air compressor (such as screw type, piston type), select special lubricating oil (such as ISO VG32 or VG46) to avoid mixing and causing performance degradation.
   • Oil quality monitoring: regular sampling analysis of oil acid value, viscosity, moisture content, exceed the standard immediately replaced.

5. emergency management: rapid response to unexpected risks

1. formulation of emergency plan
   • formulate emergency plans for fire, leakage, overpressure and other scenarios, and specify evacuation routes, alarm methods, and locations of emergency equipment (such as fire extinguishers and first aid kits).
2. Emergency equipment configuration
   • fire fighting facilities: The machine room is equipped with dry powder fire extinguishers (at least 2 per 50 ㎡) and automatic fire extinguishing system (such as heptafluoropropane gas fire extinguishing).
   • Leakage treatment: Prepare adsorption materials (such as sand, linoleum) and gas masks for lubricating oil or refrigerant leakage treatment.
3. Emergency drill
   • organize an emergency drill every six months to simulate equipment failure, fire and other scenarios, and test the response speed and disposal ability of personnel.

Intelligent 6. Monitoring: Technology Enabling Security Upgrade

1. remote monitoring system
   • through the Internet of Things sensor real-time upload pressure, temperature, vibration and other data to the cloud platform, to achieve remote monitoring and early warning.
   • Set threshold alarm (e. g. send SMS notification when exhaust temperature ≥ 100 ℃) to find hidden dangers in advance.
2. Predictive maintenance
   • use big data to analyze equipment operation data, predict the time of failure (such as bearing remaining life prediction), schedule maintenance in advance, and avoid unplanned downtime.

Case: Hospital air compressor safety practice

the compressed air system of a tertiary hospital adopts the following safety measures:

• environment the independent machine room is equipped with explosion-proof screw air compressor, dehumidifier and exhaust fan, and the temperature is controlled at 25 ℃;
• protection: The air tank is equipped with double safety valves (one for use and one for standby), and the pressure gauge is provided with a red warning line;
• operation: Operators shall take up their posts with certificates and fill in the Air Compressor Operation Record Form every day;
• maintenance: Replace the "three filters" (air filter, oil filter and oil) every 500 hours, and overhaul once every 2 years;
• emergency automatic fire extinguishing system is equipped in the machine room, and fire emergency drill is organized once a year.
  Effect: The system has no safety accidents for 5 consecutive years, energy consumption is reduced by 18%, and equipment life is extended by 30%.
