Key Maintenance Points for Nitrogen Generator in Summer day
► Daily Maintenance Measures
In the daily maintenance of the nitrogen generator under hot weather conditions, it is crucial to ensure that the generator operates under stable power supply, gas source, and temperature conditions. Special attention should be paid to the stability of the power supply voltage to minimize damage to the controller and solenoid valves. At the same time, closely monitor the pressure of the air storage tank and keep it within the appropriate range of 0.6 to 0.8 MPa to ensure it is not lower than the rated value.
In addition, every day, the automatic drainage port must be checked to prevent blockage that could lead to loss of drainage effectiveness. If the drainage port is found to be clogged, it can be disassembled and cleaned, and the manual valve can be slightly opened and the self-release valve closed for cleaning. During the cleaning process, it is recommended to use soap foam for thorough cleaning.
Regularly conduct detailed inspections of the three pressure gauges on the nitrogen generator. Especially when the equipment malfunctions, it is necessary to establish daily records of pressure changes so as to monitor the flow meter and nitrogen purity at any time. At the same time, it is essential to maintain the nitrogen purity in the exhaust gas to ensure the stability of the system. Additionally, it is necessary to regularly check the cooling effect of the cold dryer to prevent it from failing due to the machine generating nitrogen in water, thereby avoiding the risk of carbon molecular sieve poisoning.
During daily maintenance, it should be carried out according to the requirements of the actual equipment code. This includes checking the sensitivity of the solenoid valve and pneumatic valve at any time, confirming whether the pressure range of the pressure regulating valve is within a reasonable range, and also verifying the accuracy of the gas analyzer. It is also necessary to pay attention to the compression state of the absorption tower, whether the exhaust of the muffler is normal, and whether the cleaning degree of the inner tube of the flow meter meets the standard.
► Maintenance Precautions for Equipment
When repairing the nitrogen generator, a series of steps and precautions must be followed to ensure the safe operation of the equipment. These points cover all aspects from routine inspections to professional repairs, helping to promptly identify and solve potential problems.
When maintaining the nitrogen generator, several key aspects need to be paid attention to in order to ensure the continuous stability and operational safety of the equipment. This includes conducting tests on the air treatment process to ensure the cooling effect of the cold dryer; regularly replacing the tubular filters to optimize the air quality; and not neglecting the replacement of activated carbon, which is responsible for the oil removal process and reduces the oil content in the air, thereby preventing the carbon molecular sieve from being contaminated. Additionally, the testing and calibration of the nitrogen analyzer are also crucial. The p860 series nitrogen analyzer typically has a lifespan of 2-3 years, and it is recommended to replace it when the expiration date is reached to ensure that the nitrogen purity of the nitrogen generator is not affected. Moreover, the inspection of the solenoid valves and pneumatic valves should not be overlooked. To ensure the stable operation of the equipment, it is recommended that users have spare parts on hand. Finally, the nitrogen production analysis test of the carbon molecular sieve of the nitrogen generator will verify whether the output meets the standards. During maintenance, carbon molecular sieves need to be added or replaced according to the actual usage situation.
