The safety inspection of air compressors involves many aspects to ensure the normal operation of the equipment and the personal safety of users. The following are air compressor safety inspection items based on multiple authoritative sources:
1. electrical system check
- grounding and leakage inspection: Ensure that the electrical system is connected to the ground wire to prevent electrical leakage. Check whether the insulation of the power cord is intact, whether there is any damage or aging phenomenon.
- Switch and controller inspection: Check whether the pressure switch and temperature control switch work normally. Ensure that the wiring in the control cabinet is neat and loose, and that all electrical components are not overheated or burnt.
- Safety device inspection: Check whether the safety devices of the electrical part are in good condition, such as overload protection, short circuit protection, etc.
2. Pressure System Inspection
- calibration of pressure gauge and safety valve regularly check the pressure gauge and safety valve to ensure accurate indication and sensitive action. The calibration cycle of pressure gauge and safety valve is usually at least once a year.
- Pipeline and valve inspection: Check whether the high-pressure pipeline valve is well sealed and free of leakage. At the same time, check whether the pressure sensor is working properly to ensure the accuracy of pressure control.
- Leakage inspection: Check the compressor for leakage, especially the connection parts and seals.
3. gas system inspection
- filter and meteorometer cleaning: Check whether the filter and meteorological meter are clean and clogged. Regularly clean or replace the filter element to ensure smooth gas flow.
- Inspection of oil filter and oil cleaning equipment: Check whether the oil cleaning equipment such as oil filter is working normally to prevent oil pollution from affecting the performance of the compressor.
- Gas quality inspection: For occasions that require high-purity gas, check whether the quality of the gas meets the requirements regularly.
4. equipment body inspection
- lubricating oil inspection: Check whether the lubricating oil of the oil pan is sufficient and has deteriorated. Regularly replace the lubricating oil, and clean the oil pool and oil circuit.
- Tightening and sealing inspection: Check whether the connection parts are tight and the sealing parts are well sealed. Special attention should be paid to the connection between moving parts and high-pressure pipelines.
- Inspection of cooling system: For water-cooled air compressors, check whether the cooling water system is unblocked and whether the cooling water flow is sufficient. At the same time, check whether the water quality of the cooling water is clean to prevent scale and corrosion.
Inspection of 5. fire and explosion prevention measures
- inspection of degreaser and brake pad: Check whether the oil remover works normally, scrub the brake plate and friction plate to prevent oil accumulation from causing fire.
- Nozzle and piping inspection: Check whether the nozzle is blocked to ensure smooth gas flow. At the same time, check whether there is any leakage point in the pipeline system to prevent gas leakage from causing fire or explosion.
- Inspection of fire fighting facilities: Ensure that the air compressor room or equipment is equipped with qualified fire-fighting facilities, such as fire extinguishers and fire hydrants. And regularly check the integrity and effectiveness of fire fighting facilities.
6. operation and maintenance inspection
- compliance with operating procedures: Check whether the operator strictly abides by the operating procedures and safety system of the air compressor. Ensure that the operator carries out the necessary inspection and preparation work before operation.
- Maintenance records: Check whether the maintenance records are complete and accurate. Ensure that the air compressor is maintained in accordance with the specified maintenance cycle, and record the content and time of each maintenance.
- Training and certification: Check whether the operators have received professional training and have certificates. For special operation posts, such as gas welding (gas cutting) operators, they must hold a special operation certificate before taking up their posts.
7. Other Considerations
- environmental and Ventilation Inspection: Ensure that the air compressor operation area is kept clean and dry with good ventilation. In particular, the air tank should be placed in a well-ventilated place to avoid direct sunlight and high temperature baking.
- Inspection of emergency shutdown device: Check whether the emergency shutdown device is intact and reliable. In an emergency, the operator can quickly cut off the power supply or take other measures to stop the air compressor.
- Identification and Warning Inspection: Set up obvious safety signs and warning signs in the air compressor and its surrounding area to remind operators and other personnel to pay attention to safety matters.
In summary, the safety inspection of air compressors involves electrical systems, pressure systems, gas systems, equipment bodies, fire and explosion-proof measures, operation and maintenance, etc. Through regular safety inspection and maintenance, the normal operation of the air compressor and the personal safety of users can be ensured.
