Nitrogen generator is a device for generating nitrogen, which plays a key role in many industrial applications. Due to its complexity, nitrogen generator repair may involve multiple aspects. Here are some general steps and precautions on equipment maintenance and fault investigation: maintenance includes daily maintenance, fault investigation, and specific repair steps. This article provides some detailed guidelines to help you better understand and handle related issues of nitrogen generator.
Nitrogen generator failure performance
There may be many reasons for the failure of nitrogen generator, and the main reasons are the following conditions: the purity of nitrogen is not up to standard, the nitrogen generator is abnormal operation, the exhaust tower exhaust is incomplete The cutter valve switching is unreasonable, carbon molecular sieve poisoning, adsorption pressure, and excessive adsorption pressure are manifested in the data as> 0.8MPa and the adsorption pressure is too low, the gas production is too large, and the decreased adsorption pressure causes the filter to be too large, as well There are many reasons such as the failure of the pneumatic valve or the failure of the air leakage nitrogen analyzer.

Fault investigation
If the leakage of the exhaust valve (replacing the air valve or the sealing part of the pneumatic valve) in the air exhaust valve is not completely exhausted, the air -to -air valve is overly adjusted to adjust the air -to -air valve. Too high need to reduce air intake pressure. The adsorption pressure is too low or unstable requires the air can to stabilize the pressure. The air leakage of the unidirectional valve replace the unidirectional valve or inner sealing parts. Compressed air intake pressure is too low, check the first -stage air pressure pipe pressure gauge of air compressor and exhaust pressure to confirm whether the pressure is greater than 0.6 MPa. It also checks whether the cooling dryer suction machine filter is blocked, causing low intake pressure. It is also necessary to consider whether it is a carbon molecule sinking. If it is triggering the carbon position, the carbon molecular sieve should be added to avoid carbon molecular sieve. And if the carbon molecular sieve has been severely powdered, and the nitrogen generator consumer and nitrogen storage gas tanks are directly sprayed out, and the carbon molecular sieve is needed to completely clean up and fill in the carbon molecular sieve. These problems are only a small part of the possible part of.

Repair work
Disclosure and power outage: Before performing any nitrogen generator repair, make sure the equipment stops running and disconnects the power, and abides by safety operating procedures. Disassembling and inspection, disassembled related components (such as filters, valves, coolers, etc.) according to the type of faulty type. Carefully check the wear, corrosion and sealing of each component. Replace the damaged parts in time, change the damage or failure components in time according to the results of the inspection to ensure the use of the original or qualified replacement parts. Be careful to re -assemble the equipment in the order of disassembly to ensure that all connections are tightened without leakage. During the assembly process, pay attention to placing the pads and sealing ring to prevent the air leakage. After the assembly is completed, the device is activated to observe whether the operation is normal. Check the flow, pressure and purity of nitrogen to ensure that the equipment works within the range of normal parameters.
Nitrogen generator repair requires certain professional knowledge and experience. When dealing with the electrical part, be sure to ensure that the equipment is powered off. During the maintenance process, be sure to wear appropriate personal protection equipment such as gloves, goggles and earplugs. Before repairing, it is recommended to read the device manual carefully and follow relevant operations and safety procedures. If you are not sure how to repair it, it is recommended to seek the help of professionals to ensure the normal operation of safety and equipment.
