Nitrogen generator is a very important gas production equipment, which can provide high-quality nitrogen supply for production in different industries. In order to ensure its normal operation, it is necessary to take some maintenance measures. The following is an introduction to the maintenance of the nitrogen generator.
1. Daily maintenance
Daily maintenance is the monitoring and maintenance of the basic operating status of equipment, mainly including the following contents:
① Check whether the operation of each mechanism and instrument is normal, and whether there is looseness, wear, vibration, etc;
② Check whether the indications of the oxygen supply pressure gauge and the nitrogen flow meter are normal;
③ Check the cleanliness of gas processing equipment (such as filter elements, etc.). If dust, oil, etc. are found, they need to be cleaned in a timely manner;
④ Check whether the cooling water system of the air compressor and cold dryer is normal, and if necessary, add water in a timely manner;
⑤ Clean the surface of the equipment to keep it clean and tidy.
2. Regular maintenance
In addition to daily maintenance, it is also necessary to inspect the equipment one by one and troubleshoot and handle existing problems, mainly including the following:
① Conduct a comprehensive inspection of the equipment, such as checking whether there is abnormal wear or damage to the gas generating device, cold dryer, air compressor, adsorption column, and other equipment, and timely replace the required spare parts;
② Check the air filter of the equipment and ensure its cleanliness is maintained in good condition. If it needs to be replaced, replace it in a timely manner;
③ Check the connection of each pipeline, and the pipeline connection should be well sealed without air leakage;
④ Clean and maintain gas processing equipment, such as replacing filter elements, draining water, etc;
⑤ Check and clean the control circuit, such as checking whether the performance of the sensor is normal, and checking the connection of the power line;
⑥ Regularly check the water level in the machine. If the water level is too low or too high, it should be handled in a timely manner.
3. Annual Maintenance
Annual maintenance refers to thorough maintenance and inspection of equipment to ensure long-term stable operation of the equipment. The specific content is as follows:
① Disassemble the equipment, clean and inspect all components, such as checking the fastening of screws, lubrication of bearings, and balance of the base;
② Replace severely worn parts;
③ Further maintain and interpret the equipment to ensure that it achieves better working conditions;
④ Inspect key components such as safety valves and pressure gauges to ensure the safety and reliability of the equipment.
It should be noted that maintenance should be carried out in accordance with strict operating procedures to ensure the safety of operators, while also extending the life of the equipment. When using a nitrogen generator, it is necessary to strictly comply with the operating requirements, such as regulating the gas pressure and flow rate used to ensure the normal operation and service life of the equipment.
