During the operation of nitrogen generation equipment, various problems may arise, so we need do the Nitrogen generator maintenance. The faluts involve mechanical components, electrical systems, control systems, and various parameters in the nitrogen production process. This article will enumerate two of the most common issues and provide corresponding solutions to customers.
Nitrogen generator faults 1: Cylinder Alarm
During prolonged use of nitrogen generation equipment, the molecular sieves inside the adsorption tower may settle to a certain extent. Under the synchronous compression of the compression cylinder, the molecular sieves can be prevented from pulverizing. However, when the molecular sieves settle to a certain extent, it may affect the output and purity of nitrogen gas.
Our company is equipped with a cylinder alarm device. When the cylinder stroke reaches the first alarm position, the control system emits intermittent audible and visual alarms, prompting the user to add molecular sieves as soon as possible. At this time, the nitrogen generation equipment can still continue to operate, while the audible and visual alarms persist simultaneously. The principle of cylinder alarm is usually to monitor the pressure, temperature, motion status, and other parameters of the cylinder through sensors or monitoring devices. When some parameters of the cylinder exceed the preset safety range or abnormalities occur, the alarm device will emit an alarm signal. Usually in the form of sound or light, to remind operators to pay attention and take timely measures to deal with it.
If the user continues to use the equipment and the molecular sieves continue to settle to a certain extent. When the cylinder stroke reaches the second alarm position, the nitrogen generator will automatically depressurize and stop. While the control system emits continuous audible and visual alarms. At this time, molecular sieves should be added immediately. Otherwise, the control system will refuse to work!
Note! To avoid affecting your nitrogen usage, please contact our after-sales service department to arrange a nitrogen generator maintenance during the first alarm. And complete the addition of molecular sieves before the second alarm.
Nitrogen generator faults 2:Nitrogen Purity Alarm
During the use of the nitrogen generator, improper operation, damage to the adsorption bed, or unstable supply gas pressure may cause the nitrogen purity to fail to meet standards.
When the product nitrogen does not meet the purity requirements, the control system will emit intermittent audible and visual alarms and automatically shut off the nitrogen supply. If the unqualified gas continues to be unqualified for more than 1 hour, it indicates that the equipment is operating abnormally and cannot produce qualified nitrogen. The control system will automatically depressurize and stop, emitting intermittent audible and visual alarms. At this time, the nitrogen generation equipment should be checked to find the cause.
Note! When the product nitrogen purity alarm occurs during equipment operation, users can first reduce the nitrogen production to ensure usage. And then check the nitrogen generation equipment to find the cause.
Other Nitrogen generator maintenance and faults
Gas Leakage: The pipeline, joints, or valves in the nitrogen generator system may leak, resulting in decreased nitrogen production or unstable pressure.
Solution: Regularly check for leaks in pipes and joints, ensure that valves are tightly closed, and replace seals when necessary.
Abnormal Pressure: The compressor or gas storage equipment of the nitrogen generator may experience abnormal pressure. Resulting in the inability of the nitrogen generator to operate normally or excessively high nitrogen pressure.
Solution: Regularly check the operating status of the compressor and gas storage tank. Maintain the equipment properly, and adjust the equipment parameters when necessary.
High Temperature: The nitrogen generator may experience high temperatures during operation, affecting the efficiency and purity of nitrogen production.
Solution: Check the cooling system of the nitrogen generator to ensure normal operation. Clean the cooler in a timely manner to maintain heat dissipation.
Unstable Gas Supply Pressure: The unstable gas supply pressure of the nitrogen generator affects the normal nitrogen generation process.
Solution: Check the pressure regulating device and pipeline of the gas supply system to maintain stable gas supply pressure.
Regular equipment maintenance and inspection, can effectively prevent and solve the problems that may occur during the use of nitrogen generators. As well as proper operation and problem-solving methods. If you encounter complex faults, please contact our company immediately.
