XH-SC series of positive pressure ventilation analysis proof cabin 1. Scope XH-SC series of positive pressure ventilation analysis proof cabin products. Used in oil refining, chemical, metallurgical, pharmaceutical and light industry production, a variety of process gas line analyzer and a variety of online water quality analyzers provide on-site security and protection of the installation space. 2, cabin size manufactured according to user needs. Generally outside cabin size 3000mm (length) × 3000mm (width) × 3000mm (height) said. Cabin is non-standard products, its size can be determined according to the number of maintenance space analyzer, type, complexity and operating system, and should leave appropriate room. By long-distance transport conditions, its dimensions are generally as follows: Length: Outdoor body 2.5 ~ 6.5m (taking into account the standard length and lifting steel, structural strength transportation problem, a single analysis cabin length should not exceed 6.5m, if the length of 6.5m, may A modular structure, split production, transportation to the site after it combined into one, but also can achieve two analysis cabins). Width: Outdoor body 2.5m, the broadest should not exceed 3.0m (by road transport width limits, the width should not exceed 3.0m). Height: Outdoor body 2.5 ~ 3.0m (subject through the overpass, tunnel height limits), the ceiling height 2.2 ~ 2.8m. 3, explosion-proof cabin mechanical structure and material requirements ⑴ skeleton, base and roof huts analysis of the skeleton, the base and the roof is metal components, welded using steel, we should have sufficient strength and rigidity to ensure that analysis hut in load lifting, translation and when transportation is not deformed. The main frame of the base should adopt 12 # to 20 # channel, under the floor of the keel with two 10 # to 12 # channel or beam as support beams, the main frame, floor keel and support beams should be welded connections, ensure maintenance personnel indoor walking floor without tremor. Roof frame and the main beam should adopt 10 # to 12 # channel, with 8 # to 10 # channel as the main beams and roof supports in the width direction of the keel shall be welded connections, to prevent distortion. Roof should have a certain inclination, the slope of at least 4%, may be in A-type or side slope structure does not allow the use of flat top, to prevent water accumulation. (2) the inner and outer walls and roof panel exterior wall panels should use 1.5mm # ~ 2.0mm steel plate, the plate can be assembled Π-type structure is formed facades, in the case of the welding process can be guaranteed, it can be ribbed galvanized plate welded to form the outer walls. Use Π type plate assembly structure of external wall panels should use stainless steel (304SS, is recommended to use stainless steel wire drawing film board), can also be also be used galvanized steel, spraying the surface treatment must be carried out using galvanized steel, sprayed color is white or international gray. Interior wall panels and ceilings should use 1.5mm # ~ 2.0mm steel production, co-Rong-proof cabin material galvanized steel or cold rolled steel, users may also require the use of stainless steel plate. Must be carried out when using galvanized steel or cold rolled plate surface spraying, spraying color: white lacquer ceilings, interior panel is white matte paint. Roof panels designed to be effective rain, use fastening design of Assembled rain or rain welded flat design. Material 1.5mm # ~ 2.0mm stainless steel, ensure long-lasting performance corrosion-resistant roof surface, the outer top load-bearing capacity ≥250kg / m2 (weight of two people) without permanent deformation. Padding between the inner and outer walls and roof insulation within ⑶ flame retardant insulation materials (mineral wool, etc.), insulation thickness is generally 70 ~ 75mm (3in), cold or hot areas should thicken to 80 ~ 85mm. ⑷ floor floor should be skid plate, use a 4 ~ 6mm steel production, materials can be used according to user requirements pattern stainless steel, galvanized steel may be used, or the pattern of hot-rolled steel, galvanized steel or hot-rolled sheet surface must spraying, spraying color is generally gray, necessary, to add a layer of anti-static plastic plate. Cabin avoid possible accumulation of gas inside the blind spot and grooves at the cabin level should have the right to open a manual or automatic vents to prevent gas accumulation. Sample preparation unit, carrier gas cylinder, standard cylinder and manual analysis laboratory sampling points should be located outside the cabin. 4. Distribution analysis cabins cabin lights, fans, air conditioners, repair outlets and other public facilities from industrial supply. Analyzer system, detection alarm and interlock system installed by a UPS power supply. 5, explosion-proof cabin safety analysis combustible gas detection and alarm system detector selection and signal detection probe transmitter integrated structure of the product, and with a local display headers and contact signal output. Toxic gas detector when the sample or the ambient gas contains toxic components shall be disposed of toxic gas detection alarm and asked for the same combustible gas detection alarm. Differential pressure transmitter analyzer houses according to the internal volume of the number of different size installed to detect differential pressure transmitter on Positive pressure inside the cabin. The principle of differential pressure transmitter signal to the PLC controller provides for 2 out of 3 that the PLC via a pressure signal analysis power of non-explosion-proof electrical equipment inside the cabin of cut control, must be subject to three differential pressure becomes hut the transmitter, there are two or more safe and gives lower than a predetermined pressure value, PLC was given in the analysis hut off the power of non-explosion-proof electrical equipment orders. Sound and light alarm devices means siren, lights (rotating flash type), mounted outside the hut. Explosion alarm control box mounted small programmable logic controller (PLC or processor), features a variety of lights and buttons on the panel. Its role is to secure detection and alarm system control, to achieve local alarm (hut indoor and outdoor), a control room alarm and interlock functions (eg start the fan and open the instrument air exhaust commutation). If you have any technical questions, please call us. 0552-7221188 Anhui, the new contract - a professional manufacturer of explosion-proof cabin! I. Overview analysis hut is used for material composition and content of the production process for continuous automatic spot measurement, analysis and control, to meet the special environmental conditions Online analytical instruments required for complete systems, such as temperature, humidity, dust explosion etc., can be widely used in petroleum, refining, metallurgy, light industry, medicine, biochemistry and other industries with flammable gases dangerous places. Second, the main technical parameters Rated voltage: AC220 / 380V explosion-proof air-conditioning power: 1.5 Ventilation: Continuous + gap explosion Ting electric power: 2KW Air pressure: 0.3 ~ 1.0MPa explosion-proof fluorescent lamp: 2x40W gas consumption: 2.0 ~ 25m3 / h Explosion Emergency Light: 1x40W Protection: IP65 air connection: G1 / 2 'The product features built-proof distribution box, explosion-proof junction box, LED explosion proof fluorescent lamp, explosion-proof emergency lights, explosion-proof air-conditioned interior as required, explosion-proof electric or steam heating Ting device has built-needed bench, analytical instruments and other analysis cabin shock, anti-static, fire flower, dust, interference, etc., for the instrument to provide a good operating environment analysis cabin dimensions determined according to user needs four, security measures 1 inside cabins have sustained a small flow of gas and the gap filled inflatable hut to ensure clean air, safe. 2, installed inside the cabin combustible gas alarm device, if combustible gases, the alarm work, warning lights, explosion-proof alarm bells, explosion-proof solenoid valve, explosion-proof exhaust fan automatically energized at this time a lot of fresh air into the cabin filled, will air containing explosive gases discharged from the hut, hut to ensure safety. 3, the cottage has a good internal and external grounding.
