Industrial oxygen generators are responsible for compressing air and providing high-pressure oxygen. Due to the particularity of their working environment and high-pressure characteristics, safe operation of oxygen generators is crucial. Any improper operation or failure may lead to production interruption, equipment damage or even personal injury.
1. Safety operating procedures for industrial oxygen generators
1. Inspection before operation
Before starting the industrial oxygen generator each time, a comprehensive inspection should be carried out to ensure that the equipment is in a safe and stable working state. The inspection items include:
Electrical system inspection: Confirm that the power supply line and switch equipment are normal, check whether the wiring of the electrical control system is firm, and avoid equipment shutdown due to electrical failure.
Air pipeline inspection: Check whether the air intake pipeline, exhaust pipeline and connection parts are well sealed to ensure that there is no air leakage, prevent gas waste and potential safety hazards.
Lubricating oil and coolant inspection: Ensure that the quality and quantity of the lubricating oil meet the requirements and whether the cooling system is operating normally. Lack of lubricating oil or coolant will cause the equipment to overheat and reduce the service life of the equipment.
2. Equipment startup and operation
Slow start: When the air compressor is started, a slow start procedure should be used to avoid the instantaneous impact force caused by sudden acceleration from damaging the equipment.
Monitoring operating parameters: During the operation of the equipment, the operator needs to monitor key parameters such as pressure, temperature, and flow in real time to ensure that they are within the safe range. Any situation that exceeds the set parameters should be handled immediately to avoid overload and equipment failure.
Avoid overload operation: During the operation of the oxygen generator, long-term overload operation must be avoided, especially in high temperature environments. Overload work will not only cause equipment damage, but may also cause safety accidents.
3. Inspection and maintenance after operation
During the use of the air compressor, regular inspections should be carried out, especially after the equipment has been running for several hours, to check whether the equipment has abnormal vibration, noise or heating. In addition, daily maintenance tasks such as cleaning the filter element and replacing the lubricating oil also need to strictly abide by the operating procedures to ensure the long-term and stable operation of the equipment.
2. Emergency treatment measures
During the operation of the industrial oxygen generator, some emergency situations may be encountered, such as equipment overheating, abnormal pressure, gas leakage and other problems. In these cases, operators should take prompt and effective measures to reduce accident losses.
1. Equipment overheating
If the oxygen concentrator overheats, first check whether the cooling system is working properly. Possible causes include insufficient coolant, cooling fan failure, or cooling system pipe blockage. The treatment methods are as follows:
Stop immediately: First cut off the power supply and turn off the air compressor to prevent the equipment from continuing to operate at overtemperature.
Check the cooling system: Check the flow state of the coolant and whether the cooling fan is operating normally, and clean the pipes or replace the coolant in time.
Cooling treatment: If necessary, external cooling equipment can be used to help cool the oxygen concentrator. After the temperature returns to a safe range, the equipment can be restarted.
2. Abnormal pressure
If the oxygen concentrator has too high or too low pressure, measures must be taken immediately:
Excessive pressure: The pressure control valve should be closed quickly, the amount of gas output by the compressor should be reduced, and the exhaust valve and pressure valve should be checked for normal operation. Check whether there is a pressure sensor failure or system leakage.
Too low pressure: If the pressure is insufficient, first check whether the air filter is blocked. If the filter element is normal, check whether there is wear inside the compressor, and repair or replace related parts in time.
3. Gas leakage
Gas leakage is a common safety problem of industrial oxygen generators. It may be caused by loose pipe connections, aging of seals, etc. The treatment measures are as follows:
Cut off the gas source: Stop the operation of the oxygen generator immediately, turn off the gas source, and avoid leakage expansion.
Find the source of the leak: Use a leak detection instrument to locate the leak point, check all joints and seals, and replace the seals or reinforce the connection parts in time.
Ventilation and evacuation: In the event of a gas leak, the ventilation system should be started immediately to evacuate the on-site personnel to avoid accidents such as fire or poisoning.
4. Electrical failure
Electrical failure may cause the air compressor to shut down or run unstably. The treatment methods include:
Power-off inspection: In the event of an electrical failure, first cut off the power supply to prevent electrical fires.
Check electrical components: Check whether the power cord, switch, and terminal are loose or damaged, and replace damaged components if necessary.
Professional maintenance: Electrical failures should be handled by professional electrical engineers to avoid secondary damage caused by improper operation.
