Be Sure To Ensure That The Location Of The Experimental Platform Is Reasonable!

Generally, we will consider a series of problems when choosing the experimental platform, so that in the process of use can be more safe, so that its performance can be fully played. But what is the best way to choose the position of the experimental platform? In fact, you can take a look at the following article introduced content:

In order to ensure the safety, effectiveness and economy of the laboratory test bench in the operation process, it is necessary to reasonably determine the position of the test bench so as to discharge the harmful gas generated in the experiment process as soon as possible, so as to avoid pollution to the laboratory environment, and it is also necessary to effectively control the pollutants in the experiment. When determining its location, it should be combined with the technological situation of the building and the experimental platform to avoid the facilities in the position where the air flow is closely connected and the personnel frequently passes by. It should be set to the position where the air flow interference is less, so as to prevent the impact on the exhaust air of the experimental platform.

Secondly, attention should be paid to avoid placing the test platform around the precision instrument, otherwise it will have an impact on the precision instrument due to the exhaust of the test platform. According to relevant standards, when the experimental platform is parallel to the drafts, the distance from the door should be kept at about 1m. If it is perpendicular to the drafts, there is a position of 3m between the two cabinets arranged face to face on the basis of about 1m from the door at the near end.

In laboratory construction, the selection of fume hood and determine the installation position of fume hood, need to choose the type of fume hood, material, shape, etc., according to the content of the experiment, usually to consider. The following:

Use of drugs: When using organic matter or other special reagent experiments, to give full consideration to its control of wind speed. Heat source: When using equipment with heat source, the amount of ventilation required to remove heat should be considered to determine the power of the fan when the heat exceeds 2000 kcal/hour.

When there are radioactive substances or perchloric acid experiments: special fume hood should be selected, and the inlet wind speed must be set greater than 0.5m/s.

When using large equipment for experiments: consider the effective size of the interior and leave the necessary space for exhaust air.

Material: When using special acid laboratory fume hood, it is necessary to consider the material of fume hood, such as semiconductor industry, corrosion industry, etc., must be manufactured with anti-corrosion materials.

External size: Select its external size according to the experimental content, too large volume will cause wave waste, too small affect the use.

Environmental protection: If the harmful gas discharged must be ensured in lower than the national environmental protection requirements if it exceeds the national health standards, the corresponding purification device should be installed.

Energy saving: As far as possible to save energy, in the room with heating or air conditioning should be used to supplement the air shape fume hood or choose a fume hood with air volume control. When choosing the fan, its power should also be determined according to the need, and it is not suitable to blindly increase the exhaust air volume and pressure. The power consumption can be reduced by frequency converter or variable wind speed fan.

In short, when you choose the position of the experimental platform, you can refer to the above content, and you don't have to worry about choosing the position of the experimental platform.
