IINitrogen hydrogen air integrated machineTechnical Specifications

3、 Instrument features:

1. Laboratory instrumentation can replace traditional high-pressure steel cylinders. Can be used separately or simultaneously; Intermittent use advocates continuous use; And the purity of the produced gas does not decrease.

2. Easy to operate, simply turn on the power switch to produce gas with stable output flow. The nitrogen and hydrogen systems are equipped withLEDDigital display, more eye-catching and intuitive.

3. The nitrogen part adopts a new technology of compound purification to improve purity, truly solving the problem of two gases and one bottle in the laboratory;

（2） The hydrogen section adopts a high barrel tower structure electrolytic separation cell, which can simultaneously store liquid, produce hydrogen, and discharge oxygen. It has a large electrolysis area, low cell temperature, and high purity, making it the best replacement for plate electrolysis cells.

（3） The air section has the advantages of three-level purification, two pole voltage regulation, and multi-level protection.

4. Both the nitrogen and hydrogen systems of this instrument are equipped with non reflux devices, which can effectively ensure that the instrument has no reflux phenomenon.

5. Daily use only requires adding distilled water.

6. Efficient and energy-saving, using advanced switching power supply can improve electrolysis efficiency.

4、 Usage and Online Connection

1. Remove the instrument from the packaging box, inspect the appearance and interior for any serious damage caused by transportation, and then verify if the power cord, accessories, and certificate of conformity are complete.

2Preparation of electrolyte: 100 grams of analytical gradeKOHPotassium hydroxide is used separately with 400mlDilute with distilled water, wait for KOH to dissolve and cool, and then inject into the injection tank (internal dissolution volume 1.6)L）Then add distilled water to the injection tank below the liquid level H. (The injection port is located on the upper part of the instrument. When injecting, the injection port cover needs to be removed. After completion, press the upper cover of the instrument.)

3. Move the back panel“nitrogen”“hydrogen”“air”The sealing cap on the output port is tightened without air leakage.

4. Then firmly plug the power cord into the power socket on the back panel of the instrument to ensure safety, and turn on the power start switch; air“Air”The work indicator light is on.“N2”“H2”The system has a digital display. A few minutes later,“Air”The system working indicator light is off; (Indicates that the compressor has stopped working and the pressure has reached the set value)“H2”The digital display of the system is“000”Or approaching“000”The pressure gauge indicates 0.3MpaAt this moment“N2 ”The system is undergoing purification and emptying, and the flow rate display is high (about 10 minutes); After 10 minutes, the traffic display shows as“000”Or connect in“000”，“N2”“Air”The pressure indication of the system is all 0.4Mpa. (Factory settings)

6. The above is normal. Turn off the power switch. Translate into English“N2”“H2”“Air”Remove the sealing cap on the output port and use the corresponding Φ3Connect the pipeline to the gas chromatograph and ensure that there is no air leakage.

7. After each work is completed, simply turn off the power, and when working again, simply turn on the power switch. After each power switch is turned on,“N2”The system needs to automatically purge the purification room and gas path system, so it takes about 10 minutes.

5、 Precautions

1. This instrument does not consume during useKOHPotassium hydroxide only consumes distilled water, so distilled water can be replenished according to the situation and the liquid level should be kept between the upper and lower lines. (It is recommended to replace the electrolyte every 6-7 months and reconfigure it using the same method as before)

2. This instrument“N2”“H2”The traffic display value is for reference only. It is converted from electrolytic current. due to“N2”“H2”It is output after buffering in the gas storage purification room, so the output flow rate is stable. Therefore, it is normal for the flow rate to display 1-2 changes in the ten digits.

3. Observe the moisture adsorption of the color changing silicone gel, and users can replace it according to 2/3 of the color change of the silicone gel.

4. After working for 1000 hours, the activated carbon in the oil purifier needs to be replaced.

6、 Method for replacing color changing silicone gel

Turn off the power switch, wait for the pressure indicator to reach zero, then rotate the drying and purification chamber clockwise, replace it, and install it in the opposite direction, ensuring that the seal does not leak.

7、 Replacement of activated carbon

Turn off the power switch and wait for the pressure indicator to reach zero. Open the top plate of the instrument, then remove the stainless steel degreasing purifier containing activated carbon. Rotate the bottom cover counterclockwise, pour out the activated carbon, and replace it. (Replace with 2-5mm pencil lead activated carbon) After that, install it in sequence, and use foam water to detect leakage to ensure that the seal is airtight.

8、 Special Reminder：

If the pressure indicated on the pressure gauge is low or the digital display is higher than usual, it is generally caused by air leakage. A comprehensive leak detection should be conducted using soap solution. Especially when replacing the color changing silicone, special attention should be paid to not squeezing foreign objects at the upper and lower thread sealing rings.

When the air system is frequently at traffic lights, it is generally due to excessive flow or air leakage. It should be checked for leaks in a timely manner, otherwise it will damage the machine and prevent it from working!

3. Air source instruments are strictly prohibited from starting up without load! When not turned on for a long time, the electrolyte should be discharged from the drain pipe behind the instrument.
