air generatorCompressed air (or other gases) through a compressor and stored in a gas storage tank for use. It mainly consists of compressor, air storage tank, filter, drying room and other main components.

The air used in the laboratory has strict requirements. In order to ensure the normal operation of experiments, it is necessary to treat the air we come into contact with in daily life so that it can be used, thus giving birth to the air generator! The air generator has replaced the traditional high-pressure air bottle.

The structural principle of an air generator is generally composed of an air pump/compressor, a stabilizing system, a pressure control system, a purification system, and a display system.

The gas system adopts voltage stabilization and overvoltage protection devices to improve the stability of gas pressure and ensureair generatorSafe and reliable use. Equipped with drainage and dust filtration devices, and using stainless steel gas storage tanks instead of carbon steel storage tanks, the purity of compressed air is greatly improved, which can meet the matching needs of imported and domestic gas chromatographs.

The air generator purifies natural air to remove moisture, oil, and impurities, and outputs stable and clean air through a pressure regulator. It has the characteristics of stable output pressure and low noise, making it an ideal air substitute for high-pressure air bottles.

The usage method of the air generator is as follows:

1、 When removing the air generator from the packaging box, please check if the accessories and warranty card are complete.

2、 Check the appearance and interior of the air generator for any abnormal phenomena such as serious damage caused by transportation.

IIIair generatorPreparation and online connection before startup:

(1) Replace the sealing plug on the "air input" port on the rear panel of the instrument with the "filter" in the accessories.

(2) Tighten the sealing nut on the "air output" port on the rear panel to prevent air leakage.

(3) Connect the grounding terminal (middle piece) of the air generator power cord and the chassis shell to a reliable grounding point.

(4) Connect the power, turn on the switch, and the instrument will start working. At this point, the pointer of the output pressure gauge gradually rises to 0.4Mpa (set at the factory), and after a few minutes, the compressor stops working (set internally). At this point, loosen the sealing nut on air output A to allow it to slightly exhaust. Soon, the compressor will automatically start. During the repeated cycle of compressor start stop start, the pressure gauge should always be maintained at 0.4Mpa, which indicatesair generatorNormal. When the displacement exceeds the rated value, the pressure gauge will not be able to stabilize at 0.4Mpa.

(5) During the start stop cycle of the compressor, some water will be automatically discharged each time it stops working, but it cannot replace manual drainage, so manual drainage is still necessary frequently.

(6) After the above is normal, turn off the power, remove the pressure cap on the air output port, connect the instrument with an outer diameter pipe and ensure that it is sealed without air leakage.

(7) When working again, simply turn on the power switch.
