How to purchase laboratory air compressors for laboratory equipment

As a professional equipment for long-term contact with laboratory personnel, the quiet air compressor in the laboratory has very high requirements for noise control of the machine. The purchase of laboratory air compressor needs to be oil-free and quiet to provide a good working environment for laboratory staff.

As we all know, air compressors are widely used in our national economy and industrial and agricultural production. It can be used in construction, metallurgy, textile, chemical industry, electronics, plastics, food, military industry and other industries.

As a scientific research place, the laboratory naturally has special requirements for the selection and use of air compressors. Most of the experimental equipment are high-precision and expensive imported instruments, including but not limited to spectral instruments, chromatographic instruments, mass spectrometers, etc. in addition to providing aerodynamic driving for the operation and execution unit, the air compressor also needs to provide the carrier gas required for the laboratory equipment, The requirements for all aspects of compressed air equipment are also very high.

The high requirements of the laboratory for air compressors are mainly shown in the following aspects:

1. Output air quality

Selection of oil-free and oil-free air compressors

The oil and gas in the oil-free air compressor will affect the valves, nozzles, pollute the air or tamper with the measurement data, affecting the test results. Therefore, the laboratory will generally use the oil-free air compressor for analysis, test or quality control.

Control of drying degree of output air

As the carrier gas for analysis, a membrane dryer or a freezing dryer is generally required to completely remove the liquid water in the air and reduce the pressure dew point of the output air to about 5 ℃. Some laboratory equipment even requires the pressure dew point to be reduced to - 40 ℃ or - 60 ℃, reaching the humidity level 4 to 1 specified in iso8573-1.

Control of dust particles in output air

The laboratory analysis and test instruments have high requirements for the filtration of particulate matter in the air, generally reaching the level 2 or level 1 of solid particulate matter specified in iso8573-1, so the general air compressors are equipped with precision dust filters.

2. Noise level

As a professional equipment for long-term contact with laboratory personnel, the quiet air compressor in the laboratory requires very high noise control of the machine. At the same time, the relatively quiet environment can provide a good environment for the laboratory staff. According to the code for design of noise control of industrial enterprises (GB / j87-1985), the noise of the central laboratory shall not exceed 60dB, so the noise generated by long-term contact with laboratory equipment shall not exceed 60dB. The relevant standards of the European Union are more strict, and the noise of laboratory equipment shall not exceed 55dB, otherwise the long-term contact will cause harm to human body.

3. Working stability

A good laboratory oil-free air compressor can work reliably behind the scenes, so that scientific researchers can focus on scientific research wholeheartedly. The air compressor provides power and carrier gas for laboratory equipment to ensure continuous and reliable laboratory data analysis and measurement results. It is necessary to ensure that the air compressor can continuously output compressed air under the pressure of 5 ~ 8bar, and the equipment can ensure continuous operation. At the same time, the maintenance of the laboratory air compressor should also be very simple and easy.

4. Size

The space of the laboratory is very limited. There are many kinds of analysis and test instruments in the room, and the space left for the air compressor is not large. Therefore, the air compressor equipped with the laboratory instruments generally needs to make reasonable use of the space. The air compressor system is highly integrated, and the pump head, air storage tank, control elements and air post-treatment equipment are generally integrated into a whole, with a small floor space. At the same time, the height of the entire air compressor system is generally less than 800mm, It can be placed under the laboratory console.
