Supply Shenzhen proof horn

Explosion horn Shenzhen in Shenzhen Hong Mei ACE supply, Shenzhen, Hong Mei ACE is a specialized development and production of explosion-proof horn, powered speakers, active frets, IP network broadcasting a private enterprise voice equipment. Our production of explosion-proof horn has a quality advantage, after-sale protection products is unique. I. Overview 1 explosion-proof horn, explosion-proof type tweeter speakers are present proof speaker with good looks, the sound level intensity, noise, transmission distance, durable, good explosion-proof performance, etc., are very suitable for containing the presence of explosive gas or dust explosion in the use of the place. In accordance with the relevant provisions of the national oil industry, coal mines, coal processing enterprises, power plants, steel mills, industry, fuel repository safety and production shall be fitted with such speakers, with a variety of amplifier devices used in conjunction with a call for the PA. 2, the product is the use of special aluminum alloy series materials and special processing technology made of explosion suppression material. Over the years people door on gasoline, liquefied petroleum gas, natural gas, propane, methane and other flammable products in Meng Wei Hu, only passively careful caution and prevention, but despite this, due to some unforeseen, unexpected reasons , resulting in chemical plants, refineries, gas stations, car, tanker, oil depots, storage tanks and other accidents caused by explosions, to the state and people's property caused irreparable huge losses. Given the needs of the market, the world have developed a variety of explosion suppression materials, such as polyurethane foam, papier-mache material, film material, but some material difference in petroleum products, chemical stability, very easy cleavage broken, causing the liquid pollution, suitable for long-term use. Petroleum products of combustion explosion must have three elements, oxygen, fuel and temperature, as long as an element off the explosion would not have happened. We test a few years after repeated hundreds of times the recipe, adding a variety of trace elements, and strictly control the chemical weight percentage, made the best polygon mesh honeycomb structure materials, manufactured products and uniform internal crystal changes, increased Faren and extension, bending, elasticity. As the laminated structure in a special honeycomb mesh composition, the fuel tank cylinder cavity into a tank of countless thousands of tiny "little compartments," these "little compartments" can effectively inhibit the flame spread, while in this particular configuration unit volume has good thermal conductivity, can be quickly released most of the combustion heat absorbed, so that the final temperature of the combustion reaction greatly reduced, the reaction gas is reduced expansion program , a small increase in pressure vessels, in line with the effect that the aluminum alloy has good explosion suppression performance. 3, ACE-proof barrier effect material product advantages: You can suppress gasoline, methane, propane, diesel oil, acetone, toluene, ethane, petroleum solvents and similar substances exploded. Containing the material (metal) can effectively eliminate static electricity. When the container containing the material leak, can be directly under way with oil gas, welding repair welding. Transport tanker equipped with the material during transport, can reduce the level of the liquid sloshing. The material does not wear the container wall, the material itself is not contaminated oil, no deformation in the container, oil and other solvents in corrosion, wear and tear, not broken, do not plug all the oil, once into the long-term use. NOTE: This material is only filled container volume: cylinder ≤0.8%, spheres ≤1.0%, added in an amount of 28 ~ 32kg / m3. Second, the technical indicators 1, explosion-proof mark: ExdⅡBT6, ExdⅡCT65 2, rated power: 15VA (15W) 25VA (25W) 35VA (35W) 45VA (45W) 65VA (65W) (100 / 120V) 3, impedance: 8Ω, 16Ω 4 Audio Input voltage: 100 ~ 120V (or other value presented by the user) 5, protection: IP66 Third, the technical parameters 1, rated input: 15W 25W 35W 45W 65W 2, maximum power: 20W 30W 40W 50W 80W 4, work Voltage: 70-100V 5, the frequency response: 330-7000Hz 6, boost stage (1W / 1M): 109dB 7, the boost level (rated power / 1M): 121dB 8, mounting: bracket 9, temperature range: 50 ℃ ~ -50 ℃ 10, distortion (-6dB) 1kHz / 4kHz: 200 · / 50 · 11, Material: antistatic polyester fiber glass explosion-proof metal cavity ring 12, color: RAL7031 13, IP rating: IP67 14, Explosion-proof grade: Ex de mb IIB + H2 / IIC T5 Gb / 10ATEX 1053 Third, use 1. AEO-110 is a low-impedance load type speaker, 5VA load impedance of 8 ohms; 10VA, 15VA, 25VA, 35VA and 60VA speaker load impedance is 8 ohms or 16 ohms. Usually used close distance PA amplifier device. 2. AEO-1100 model is a fixed voltage input, input of 120V (or other value) of the audio signal through the audio transformer explosion-proof chamber and then sent to the speaker voice coil. Usually used for far distance PA amplifier device. Fourth, the method of assembly. Using three M5 screws megaphone fixed on the explosion, and the middle install rubber ring. 2. The reflective tube is screwed to the explosion-proof body. 3. The sound head is screwed to the explosion-proof body. 4. The mounting bracket is screwed to the explosion-proof body. 5. The fixation on the buildings. 6. Explosion speaker terminals in sound head, the cable passed the inlet tighten. Cable with an outer diameter of 8 mm, wire cross-sectional area of ??0.5 mm2 or more two-core cable can be. 7. M6 with internal hexagonal screws fixed to the explosion-proof chamber body, combined with top coat anti-rust oil proof, explosion-proof surface gap is less than 0.15 mm. If necessary, purchase explosion horn, speakers and other voice-proof equipment friend, can point directly to inquire and look forward to your call.
