For assistance, call toll-free at 800-343-4048These instructions must be thoroughly read and understood before installing and operat-ing this product. Modification of the unit will result in voiding the warranty. If you have any questions or concerns, please call the Technical Services Department at 800-343-4048,**********************************************************.Forotherlocationsoutside North America, please contact your local representative.Please save product packaging for future use.The Parker Balston 75-82S Explosion-Proof Zero Air Generator is certified to operate in a Canadi-an Standards Association (CSA) Class 1, Division 1, Groups B, C & D environment. The CSA logois displayed on the product label on the cover of the unit.The 75-82S will remove hydrocarbons from on-site compressed air to a total concentration of lessthan 0.1 ppm (measured as methane) at a capacity of 1000 cc/min (1). The Explosion-Proof Zero AirGenerator may be used to produce fuel air for a Flame Ionization Detector (FID) or as a zero refer-ence for any process instruments measuring hydrocarbon concentration.The Parker Balston 75-82S Explosion-Proof Zero Air Generator consists of an explosion-proofenclosure, two flame arrestors, a hydrocarbon catalyst module, and a 0.5 micron particulate filter.All internal components of the 75-82S are stainless steel to resist corrosion.Two versions of the Parker Balston Explosion-Proof Zero Air Generator are available to meetworld-wide electrical power supply specifications. The systems available are compatible with120VAC/60 Hz and 220VAC/50 Hz. Please see the ordering information on page 4 of this bulletinfor further information.Parker Balston 75-82S, 75-82S-220 Explosion-Proof Zero Air Generator ®System Description Installation, Operation and Maintenance (1) Note: The 75-82S-220 has a maximum flow capacity of 650 cm/min to meet rated hydrocarbonremoval to 0.1 ppm2Parker Hannifin Corporation Bulletin TI-7582S-KLocationTo prevent explosion and serious injury, the Parker Balston 75-82S Explosion-Proof Zero Air Gen-erator must be installed by a licensed electrician according to CSA, Class 1, Division 1, Groups B, C & D regulations. All connecting wiring for the 75-82S must be rated for at least Class A service (220°F/105°C). In group B atmospheres, conduit runs must not exceed 2" (50mm) in size. To prevent ignition in group B and C atmospheres, all conduit runs must have sealing fittings connected within 1 1/2" of the enclosure. Keep cover tightly closed while the unit is in operation.All installation, operation, and maintenance activities for the Parker Balston 75-82S Explosion-Proof Zero Air Generator should be performed by suitable personnel using reasonable care.The Parker Balston 75-82S Explosion-Proof Zero Air Generator should be located near the instruments which are being supplied with zero air from the unit. Care should be taken to protect the unit from se-vere weather conditions. There is no limit to the distance between the generator and the point of use as long as the tubing material, cleanliness, and pressure drop are taken into consideration. The zero air generator must be located in an environment where the ambient temperature is between 40°F and 100°F(4°C and 38°C).The 75-82S is designed to be wall-mounted. The unit must be mounted in the vertical position as shown in Figure 2. Do not install the unit in the horizontal position or the integrity of the zero-grade air will be compromised. The mounting holes located at the rear of the unit should be used to secure the unit to a wall using National Electrical Code (NEC) and local building code guidelines. All mounting hardware should be adequately sized to hold the weight of the 75-82S in place when pressed Air - The compressed air inlet and outlet ports on the 75-82S are 1/4" NPT. The com-pressed air supply for the 75-82S should be clean, dry, and at a pressure and flow rate greater than re-quired at the point of use. If extra prefiltration is required, contact your local representative for product recommendations.Note: The hydrocarbon catalyst module can be contaminated by high concentrations of lead, sulfur, or phosphorous compounds, heavy metals, chlorinated hydrocarbons, chlorofluorocar-bons, and long chain polymers. Care should be taken to avoid introducing these compounds into the Zero Air Generator. Specifically, assure that none of these compounds are stored near the inlet to the compressor supplying the system with compressed air. The intake for the com-pressor should be vented to the outdoors.Power - The electrical requirement for the 75-82S is 120 VAC/60 Hz, 0.5 amp. The electrical require-ment for the 75-82S-220 is 220 VAC / 50 Hz, 0.25 amp.Note: Do not install this product on a ground fault interrupt circuit (GFI). Generator electrical characteristics may cause the GFI to trip during operation.Tubing - The outlet port of the Parker Balston 75-82S Explosion-Proof Zero Air Generator is 1/4" female NPT and is located on the right side of the unit (see Figure 1). Tubing that is used downstream from the Zero Air Generator should be clean stainless steel or pre-cleaned refrigeration-grade copper tubing (1/4" O.D. x .030" wall ). Do not use plastic tubing downstream from the 75-82S. Outgas-sing from the plastic may contaminate the zero air. Use PTFE tape on all inlet and outlet NPT fittings. (Thread sealing compounds may contaminate the process stream.) All connections to the 75-82S should be suitable for use at 125 psig.If pre-cleaned copper tubing is unavailable, standard copper tubing may be cleaned by the customer. First, connect the tubing to a supply of clean inert gas (N 2, He). Next, initiate the gas flow through the tubing (5-10 cc/min.). Finally, heat the tubing with a propane torch, moving the flame at a rate of approximately 1/2 in./sec. in the direction of flow. This procedure removes waxes and oils used in the manufacture of the copper tubing.2002N-1B1-BX - If prefiltration of the compressed air is required, the Parker Balston 2002N-1B1-BX filter assembly (1/4" NPT) is ideal for removing oil, water, and particulate matter from the compressed air supply.IK76803 Installation Kit - The IK76803 Installation Kit includes all the fittings required to bring the 75-82S Explosion-Proof Zero Air Generator on line quickly and easily.72-130-V883 Pressure Regulator - To control the incoming air pressure to the zero air generator, Parker recommends the use of a pressure regulator. The 72-130-V883 is a pressure regulator with 1/2" NPT inlet and outlet ports, assembled with a 0-130 psig (0-9.3 barg) pressure gauge. For more information, please request the Analytical Gas Systems Product Catalog.W-FM7583 Flow Controller -To control the flow rate of air through the zero air generator, Parker rec-UtilitiesRecommended Accessories(see Figure 3)Figure 2 - 75-82S Mounting Dimensions and Orientation Figure 3 - 75-82S Recommended Installation Warning: Do not supply electrical power to the generator until the compressed air flow rate through the unit is at or near the rated capacity (1000 cc/min.). Operating the generator for ex-tended periods of time without compressed air will damage the heater within the catalyst module and void the warranty.Initiate the flow of compressed air to the generator and adjust the inlet pressure to the desired set-ting. The maximum inlet pressure is 125 psig. Set the flow through the generator to 1000cc/min. If the 75-82S output capacity is exceeded, the unit may not perform to specifications. It will take the 75-82S approximately 45 minutes to achieve the outlet purity specification of less than 0.1 ppm hydrocarbons. The Parker Balston 75-82S Explosion-Proof Zero Air Generator is designed to run continuously for 24 hours per day.Final Filter MaintenanceTo avoid explosion and serious injury, service must be performed by qualified service techni-cians. Disconnect the power, depressurize, and allow the 75-82S to cool for 2 hours before servicing any internal components.All maintenance activities should be performed by suitable personnel using reasonable care.The final filter cartridge should be replaced every two years or as needed to maintain flow char-acteristics. The final filter is located inside the 75-82S enclosure, downstream from the stainless steel cooling coil (see Figure 1). It is easily replaced using two 7/16" wrenches (or two adjustable wrenches). To remove the spent filter, simply use the wrenches (one as an anchor) to disconnect the filter from the tubing. Replace the spent filter with a new filter (P/N 75820) and re-assemble. Dispose of the spent filter according to local regulations.Replace the catalyst module every 2 years. Replacement of the module requires less than 30 minutes. Allow the generator to cool for 2 hours before changing the module. The only tools required are a flathead screwdriver and two 7/16" wrenches.1. Turn off the power to the generator and depressurize the unit. Allow the generator to cool for ommends the use of a high purity flow controller. The W-FM7583 Flow Controller is a flow meter and controller with 1/8" or 1/4" compression fitting ports.

气体发生器的结构及产品特点 发生器如何操作
气体发生器的结构及产品特点发生器如何操作气体发生器的结构及产品特点气体发生器壳体由上盖和下盖两部分构成。
上盖上制有若干个长方形或圆形充气孔，下盖上制有安装孔，以便用专用螺栓和专用螺母固定在气囊支架上，装配时只能用专用工具进行装配。
上盖与下盖压成一体，壳体内装有充气剂、滤网和点火器。
金属滤网安装在气体发生器的内表面，用以过滤充气剂和点火剂燃烧产生的渣粒。
气体发生器是利用热效反应产生氮气而充入气囊。
在点火器引爆点火剂瞬间，点火剂会产生大量热量，药片受热立刻分解，产生氮气并从充气孔充入气囊。
虽然氮气是无毒气体，但是副产品有少量的氢氧化钠和碳酸氢钠（白色粉末）。
这些物质是有害的，因此在清洁膨胀后的气囊时，应保持良好的通风并实行防护措施。
产品特点1.仪器通过系统压力可以自动调整氮气输出量；2.一次性加碱，日常只需补充蒸馏水；3.设有防返碱装置；4.仪器稳定，安全，输出氮气纯度更高。

一、概述 (1)
二、工作原理 (2)
三、使用与操作 (3)
四、维护与保养 (4)
五、故障诊断和排除 (4)
一、概述
•
Model 111型零气发生器是空气自动监测系统中一台关键设备。
它由零气发生器及外部的空压机系统两大部分组成。
零气发生器中有：压力调节装置、气体清洗器、反应室和温控器。
压缩机系统将空气压缩后输入到零气发生器中，零气发生器产生不含被测污染气体（如：SO2, CO, O3, NO, NO2 和 HC 等）的零气。
Model 111型零气发生器可以为各种空气自动监测系统提供足够稳定的零气。
二、工作原理
图(一)是Model 111的气体流程示意图。
图一气体流程图
图(二)是Model 111仪器组件的安装图(顶视图)。
图二仪器组件安装图
1、空气经压缩机压缩后，经过聚结过滤器将空气中的水份滤掉。
2、反应室起催化、氧化作用，它的最佳工作点在375℃，•反应室的主要做用是将空气中的CO氧化成CO2，HC及甲烷氧化成水和CO2后除掉。
3、清洁柱（PURAFIL，在氧化铝载体上涂有高锰酸钾)主要起氧化作用，•它是将NO氧化成NO2后除掉。
4、碘化后的活性碳主要起吸附作用，以除掉NO2，SO2，O3和HC等。
•••
三、使用与操作
1、将空气机的出气口接到Model 111仪器的进气口，将Model 111仪器的出气口接到Model 146仪器的进气口，或接到Model 200SPC 仪器的零气口。
2、关上压缩机的输出阀门，接上电源，调节压力控制器使得压力逐渐增加到80-90psi时，压缩机停止工作。
3、打开压缩机的输出阀门，调节聚结过滤器后面的压力调节器到 40-50psi。
4、打开Model 111仪器，仪器内部的冷却风扇将启动工作。
•温度控制器上的指示灯亮。
调节面板上的压力调节器到 30-40 psi，调节温度控制器到刻度盘上的375℃。
图(3)为Model 111仪器的面板图。
图三前面板图
5、半小时到一小时后温度控制器上的发光二极管指示灯将循环开关，使加热反应室的温度稳定，这时Model 111 仪器可以工作。
6、压缩泵将循环开关，压力被控制在80-90psi之间。
7、在实验室连续使用时，最好在Model 111仪器的进、•出口各串接一个干燥器，这是由于在实验室使用时，空压机工作时间比较长，机体发热，排出的气体遇冷凝结，水气较多，又因为气体中的水份对SO2有一定的吸附作用，使得零气的纯度不够。
经过干燥器可以提高零气质量，保证校正仪器的精度。
•
四、维护与保养
•
仪器的正确使用及经常的维护对仪器的使用寿命及产生零气的质量是一个重要保证。
因此，有必要了解仪器性能及必要的维修项目，以保证大气或污染源自动监测系统的运行。
•
1.每次巡检都要打开111零气泵的储气罐放水阀放掉积水，并检查111零气泵
是否能正常起动和停止。
如零气泵运行时不能保持一定的压力，就需要按说明书对泵进行检修。
2.检查压缩机上和零气系统中的各个气水分离器放掉其中的积水。
3.每月检查Purafil过滤器的情况。
有效的Purafil是紫色的，失效的是棕色
的。
当过滤器中的Purafil剩下20%是紫色的时候就需要更换失效的Purafil。
更换Purafil的时候，先关闭111零气泵的输出阀使111的压力降到0.0 psig. 然后从仪器上取下Purafil过滤器换上新的Purafil。
4.每年更换一次活性炭。
方法和更换Purafil的一样。
注意：Purafil和活性炭的更换频率，用户应按零气的使用情况进行调整。
5.如零气泵运行时不能保持一定的压力，就需要按说明书对泵进行检修。
6.要定期清扫仪器，特别是风扇，以保证仪器的清洁。
五、故障诊断和排除。
