Steel fume hood: a description of the material, the overall size: L1200 * 1500 * 1800W800 * H2350mm; ☆ effective operation of internal space (windows closed): L1000 * 1250 * 1350W700 * H1150mm; two, cabinet parts: 1, cabinet portfolio : mining modular cabinets of the three sections of the upper cabinet (detoxification cabinet), intermediate (operating table), the lower end of the cabinet (includes freestanding storage cabinets and a separate water, electricity, gas pipeline system to accommodate cabinet design); 2, shell : The Shanghai Baosteel cold-rolled steel production bending shape, thickness of 1.2 mm, after pickling, phosphating, electrostatic spraying epoxy powder surface. 3, lined plate: with a thickness of 5mm anti accompany special plate. 4, spoiler: The material with lined plate, spoiler mounting position and angle required to exhaust distribution, no dead ends, to ensure that the proportion of different gases can effectively discharge. 5, the operating table: 12.7mm high quality solid physiochemical board table 6, the base cabinet: the Shanghai Baosteel cold-rolled steel production bending shape, thickness of 1.2 mm, after pickling, phosphating, electrostatic spraying epoxy powder surface. 7, the bottom door panel: Material with base cabinet, housing. 8, the auxiliary air inlet: detoxification cabinet mounted below the front cover plate, cold rolled steel with punched together. Available gas source in when the window is closed. 9, adjust the door: 1) Track: made of stainless steel. 2) Adjust the door about suspension cable installation, cable required to be completely hidden in the track. When pulling up and down, no friction with the rail, to ensure the safety of the cable, and to avoid chemical corrosion problems. 3 Adjust door handle design, ergonomic requirements needed to facilitate the users to pull down force. 4 Adjust the doors open opening height 760 mm (inclusive). 5 adjustable door glass: using 5mm thick safety glass. 10, rope pulley block: 1) Pulley Holder: using thick 2mm (more) steel pressure molding machine production, teamed with a double-sided anti-drop style designed to ensure stability. 2) Pulley: The Ф35mm made of nylon. 3) Weight: The weight is about double box design. 11, set the hood: the use of polymer plastic material forming one, at the bottom of the inlet opening is rectangular, the top outlet diameter of about Ф250, export convergence nozzle height 50mm (or more), to facilitate convergence duct cover. 12. Lighting equipment: the use of full-face design lamp holder (with vents), the bottom has a 5mm thick glass, shade included 220V, 30W fluorescent one. 13, air volume: Requirements to detox cabinet average surface wind speed 0.5m / s is calculated. (Provided with the amount of exhaust from the exhaust pipe system). 14, the average surface wind speed: the doors open in the regulation, the average surface wind speed 0.5m / s case, the surface wind speed measurement points at any point, the measured wind speed within the range of values ??required to 0.5m / s ± 10% range.
