Wood and steel structure fume hood 1) The cabinet combinations: modular cabinet adopted three sections, the upper part of the cabinet (fume hood), middle (worktop), the lower end of the cabinet (includes one-sided freestanding storage cabinets and other side of independent water electricity, gas pipeline system to accommodate cabinet design); 2) OTC (fume hood) Cabinet: 16mm thick melamine use and medium density fiberboard production; OTC (fume hood) stent using 1.5mm thick cold-rolled square tube welded by , surface treatment epoxy coating; 3) OTC (fume hood) lining board: Europe and imported acid fume hood lining special thick 5mm, anti Beit board made. 4) deflector: deflector design, the material with lined plate, deflector mounting position and angle of the exhaust gas distribution, no dead ends, under standard conditions, the guide plate side and the bottom discharge outlet hood proportions of about 50 (± 10mm), to ensure that the proportion of gas can effectively exclude different, can increase the proportion of the exhaust hood outlet below 80% (or more), in order to meet the needs of different experiments. 5) operating table: 13mm solid physiochemical board table 6) base cabinet: 1.5mm thick cold-rolled steel frame of welded square tube, epoxy coating surface treatment, outside the use made of melamine board 18mm thick, and Annex height adjustment feet. 7) Bottom Door board: MDF production, and with 2mmPVC for water edge, nice. 8) Auxiliary air inlet: below on the fume hood front seal plate, cold-rolled steel with punched together. The window can be closed to provide air to reduce the rapids below the window opening. 9) Adjust the door frame and the track: A, material: stainless steel made. B, the left and right suspension damper installed cable, the cable need to be completely hidden in the track, pulling up and down, no friction with the rail, in order to ensure the safety of the cable, and to avoid chemical corrosion problems. C, adjust the door handle design, the need to ergonomic, user-friendly and down to promote biased. D, adjusting the door frame and the glass edges sandwiched embedded using combined to ensure the safety and durability. F, adjust the door full opening height 760 mm (inclusive). 10) Adjust the door glass: the use of thick 6mm (± 5%) safety glass. 11) Adjust the door suspension tightrope: Each fume hood sash around each pick one pair cable design, each cable can load 150kg (or more) is not broken, in order to ensure long-term safety. 12) rope pulley block: A, pulley holder: the thick 2mm (or more) pressure molding machine production of galvanized steel, with double-sided double-team style anti-drop design to ensure stability. B, pulley: use Ф35mm (more) integrally molded nylon lathe production. C, roller bearings: The ball bearings and steel center rod production. 13) counterweight: single counterweight box design, its vertical stroke Mute track be limited to avoid shaking collision. 14) set the gas hood: the use of polymer plastic material molded integrally molded cone shrinking acid gas collecting hood, bottom entry rectangular opening, the top outlet diameter of about Ф250mm, outlet adapter nozzle height 50mm (more) easy duct cover convergence, set hood with good gas collection angle and roundness, get a good set of gas uniformity and low pressure loss. 15) Lighting equipment: The full-face lamp holder design (with vents), at the bottom with a thick 5mm (± 5%) glass, shade included 220V, 40W fluorescent one. 16) switch: Preset the blower motor ON / OFF button switch, lighting switch, 220V10A two or three outlets, and individual instructions to be marked. 17) air flow: the requirements in a hood open windows between height 150-250mm, fume hood surface average wind speed 0.3 ~ 0.5m / s
