How to connect the electricity of the floor fume hood?

Floor-standing fume hood is an important ventilation equipment in laboratory work. The floor-standing fume hood effectively exhausts the gas in the cabinet through the ventilation system, which completely isolates the experimenters from the toxic and harmful gases and ensures the safety of the experimenters. It has the characteristics of strong explosion-proof, airtight and leak-proof, durable and anti-corrosion. The professional design and installation of the whole ventilation system can achieve effective discharge. Now all wood structures have been eliminated and all steel structures have been adopted.

Material description of floor-standing fume hood:

1. Description of the enclosure of the floor-standing fume hood: the enclosure is1.2mm.

High-quality cold-rolled steel plate is shaped in CNC machining center, cut, punched, bent and welded, then sprayed with epoxy resin powder, baked and cured at high temperature. High adhesion, strong surface hardness and corrosion resistance, beautiful appearance.

2. Description of the inner shell: It is made of 5mm ash, which is a corrosion-resistant material specially used in the laboratory to resist acid and alkali organic solvents. There are detachable holes, which are convenient for circuits, waterways and gas circuits.

3. Description of fluorescent lamp: The fluorescent lamp is hidden on the panel and does not contact with the airflow in the fume hood, so it is convenient to replace. 30W fluorescent lamp 1, 5mm tempered glass.

4. Description of floor handle: stainless steel bridge handle.

5. Description of guide plate of floor-standing fume hood: 5mm ash is used, which is a special corrosion-resistant material for laboratory and resistant to acid and alkali organic solvents.

6. Description of power supply for floor-standing fume hood: Special power socket for laboratory is adopted.

7. Window description: aluminum profile is matched with plastic profile frame. The window is made of 3 pieces of 5mm safety glass, which can move left and right. It adopts stepless balance device, which can move up and down and adjust freely.

8. Description of wind speed and noise of floor-standing fume hood: above 0.5m /sec and below 60-70dB.

9. Description of adjusting foot: The adjusting foot is made of stainless steel with a diameter of φ9mm, which is shockproof, moisture-proof and corrosion-resistant. The height of the cabinet can be properly adjusted according to the indoor floor, and the maximum adjustment range is 0-30 mm.

10. Description of gas collecting hood of floor-mounted fume hood: made of PP material.

1 1. Description of the distribution box: it meets the power supply requirements of 220V and 380V, and has leakage and motor protection devices.

12, description of control switch: 12V touch switch, centralized control of the whole circuit system.

13. process description: after all steel plates are welded, epoxy resin powder shall be sprayed, and the steel plates shall be visually smooth without solder joints. All water, electricity and gas lines are required to be safe, applicable and concealed. There is a hole in the back panel of the cabinet.

14, three guide plates make harmful gases in different height spaces be discharged from different sections respectively. The floor-standing fume hood exhausts the air in the fume hood at the speed of 0.5m/s on the working face to ensure no residual gas. The floor-standing fume hood has high efficiency, the exhaust air volume is about 1600m3/h, and the noise is low.

15. The floor-standing fume hood should be exhausted by a ventilator, controlled by an integrated panel of water, electricity, gas and ventilation, equipped with anti-corrosion and explosion-proof lighting and multifunctional (three-phase, single-phase) sockets. It is provided with a gas pipeline and a plurality of water pipe interfaces. It can meet the requirements of various tests for water, electricity and gas.

16, lower cabinet door panel:1.2mm.

High-quality cold-rolled steel plate (double layer), detachable with shock absorber, without welding connection. Cutting, positioning and punching, bending and welding, forming, pickling and phosphating, spraying epoxy resin powder, baking and curing at high temperature in a numerical control machining center.

17. the power connection of the floor-standing fume hood depends on whether it is a 220V motor or a 380V motor. 220V is better, and 380V motor must be connected by a professional electrician, for safety reasons.
