Excellent Gas Chinese HUILINHUILIN Nitrogen GeneratorModel: WG-STD495-3 Instruction BookGuangzhou Huilin Air Separation Equipment Co,LTDPart 1: OverviewPSA (Pressure Swing Adsorption)nitrogen generator is widely used in the production of N2 way around the world. Huilin high purity nitrogen generator adopted the foreign advanced technology to make N2 process in two large capacity of adsorption tower at one time. The SKD units of our product are import, integrated circuit control, oil removal and water removal and filtration device, equipped with nitrogen gas purity on-line analyzer. It has fast producing , high purity, performance, novel appearance and simple operation, convenient maintenance. Widely used in foodstuff, chemical, electronics, oil, heat treatment of metals, medicine, transport, storage and other industries.Part 2: Principles And ProcessPSA nitrogen generator mainly composed of adsorption filled with carbon molecular sieve. Due to the volume of O2 molecules is smaller than N2 molecules in the air, when the compressed air through the carbon molecular sieve, O2 is carbon molecular sieve adsorption, because the large molecule volume of N2 , which cant be adsorption and enrichment of pure N2.When the carbon molecular sieve adsorption saturation, relief regeneration, and then into the next adsorption process, when a adsorption tower producing N2, the other one relief regeneration, cycle and cycle, producing stable N2. 1 Solenoid Check Valve 6 Adsorption Tower B 2 Air Solenoid Valve 7 N2 Solenoid Vale 3 Fast Drain Valve 8 N2 Buffer Tank 4 Fast Drain Valve 9 Emptying valve 5 Adsorption Tower A 10 N2 Tank Fig.1 Nitrogen Generator Flow DiagramPart 3: Main Technical PerformanceTable 1: the performance parameters of the tablePowerAC220V（50Hz/150W）Input Air Pressure7kg/cm39kg/cm3 Output N2 Pressure0kg/cm38kg/cm3N2 Purity99.995%N2 Flow3m3/hDisplay ModeContinuous Online N2 AnalyzerPressure SwitchAutomatic Pressure Switch ControlRun-up Time10minExternal Gas Storage Tank(100-200L)MatchDimensionsLWH:5606501830mmWeight205KgPart 4: Electrical schematic diagramFig.2 Electrical schematic diagramCircuit connection:Nitrogen generator power supply is 220V.Plug the power cord into the case, and the other end is inserted into the socket.Part 5: Main ComponentFig.3 Structure diagram of nitrogen generatorOperation method:1. Plugged in, start the nitrogen generator.2. Start the air compressor, when the air pressure after reaching 7MPa,open the ball valve at the entrance of air, the nitrogen generator begin to work. Adsorption tower by time relay set the time to work,the general will be set to 4060s.3. Nitrogen generator work about 10 minutes, nitrogen purity can reach more than 95%.4. Nitrogen generator power source controlled by the pressure switc the pressure is generally set to 4 6MPa Adjusting pressure screw. Differential pressurePressure setting5. In the process of the use of nitrogen generator, when the nitrogen pressure is higher than upper limit, nitrogen generator automatically stops running; When the nitrogen pressure is lower than lower limit, nitrogen generator and automatic start running. Usually, the user can adjust according to the required pressure. Adjustment method: The user can use a small screwdriver to adjust pressure switch at the top of the two small screws. On the left side of the screw is used to adjust the differential, on the right is used to the pressure required.Part 6: Common failure and maintenanceTable 1: The common failures and troubleshooting methodsCommon malfunctionReasonSolution method1Nitrogen gas flow rate is insufficient or excessive nitrogen flow caused by nitrogen gas purityControl of the flowof nitrogen to adjustthe throttle valveThe throttle valve to the appropriate state (annotated company production equipment according to customer requirements, all valves are transferred to the best, in not familiar with the machine before the machine, to adjust the nitrogen flow cut-off valve)2Fast row does not exhaust valve or in a state of long-term exhaust1. Quick discharge valve damage2. The purge valve opening is too large1. Replace the new quick exhaust valve2. Adjust the purge valve3Nitrogen purity is not stable1 sampling gas is too large nitrogen analyzer can not identify.2 nitrogen sensor damage, nitrogen analyzer cannot detect the purity of nitrogen.1. The small sampling gas cut-off valve2. Replace the nitrogen gas sensors4Nitrogen generator doesnt work, the N2 outlet without nitrogen1.circuit short circuit2.piping failure3.solenoid valve damage1.check whether the circuit is normal2 check whether the pipeline is broken down3 replace the solenoid valvePart 7: Attention1 Nitrogen generator is high voltage control, guard against electric shock.2 Nitrogen is inert gas, people smoking too much can lead to suffocation, so in the use of process should pay attention to personal safety.3 The service life of the molecular sieve is about 10 years. You need to replace the molecular sieve, please contact your gracious presence in the guangzhou air separation equipment co.,LTD.4 Nitrogen generator warranty period is one year.CertificationThis product after inspection, meet with quality standards, granted the factory.Equipment Name Equipment NO.
