介本公司是开发和制造笑声设备的专业厂家,其前身北京北方消声设备厂。产品以结构先进、消声效果好、压力损失小和适用性强等优点博得广大用户欢迎,并获五项专利和科技成果奖。我厂在引进和消化国外先进技术的基础上,为淮南矿务局谢家集一矿“25”风井主扇(2K60-N028)风机设计制造了我国第一套OPKC型消声器,安装在垂直风道(扩散)内。经使用,用户十分满意并续订了四套。目前经过改进定型的OPKC系列消声器安装更加方便,已广泛使用OPKC系列消声声器后,噪音降到50分贝以下。为了适应水平风道安装需要,我厂开发了OPI型水平风道自联式组合消声器,安装在北京地铁前门站及和平门站,消声值达到35dB(A),受到北京地铁公司,上海地铁公司、北京地铁设计院以及各煤矿设计院等有关方面的广泛好评,目前已获国家专利权(专利号:89022213.2)。它的优点是:消声体自联组合安装;风道内不需要预埋件;不需要检修门推拉轨道结构及支架;占地空间小;安装容易、检修方便;消声效果好,压力损失小;使用寿命长、防火性能好等。不仅适用于地铁通风消声,也适合各种矿井主扇以及烧结炉抽烟风道消声等。我厂生产的OPTF行通用阻性消声器,使用在望亭电厂二十万机组、汉川电厂三十万机组锅炉鼓引风机消声、攀纲烧结炉抽烟风机消声,效果良好。为克服电厂送风机消声器布置安装困难,我厂配合华北电力设计院设计开发了OPKX型墙砌风道消声器,首先使用在大连石化公司热电厂。它克服了传统壳体消声器布置安装困难的缺点,使现场美观,安装维修方便。同时它不仅提高了消声性能,减小了二次噪音,降低了管路压力损失,而且大大降低了造价,深受用户欢迎。目前已被一些电力设计院推广到其他电厂及二十万以上机组使用,成为我厂系列产品。 我厂生产的OBZK型、OPZKY型阻抗复合消声器,性能全面超过国标T701型消声器,使用在北京机场、西郊宾馆等空调系统,效果也十分良好,被各设计单位广泛采用。我厂除上述产品外,还生产各种隔声罩、消声通风窗、隔声门、吸声屏、大型空气过滤器以及高压排放消声器等。同时,我厂以其雄厚的技术实力,承接噪声综合治理工程、各种非标消声设备的设计制造。 我厂产品质优价廉、供货及时、服务周到、代办托运、实行三包。我厂可派出包括高级工程师在内的技术人员赴现场服务,为用户解决技术难题。我厂欢迎与用户、尤其是设计部门合作开发更合适用户使用的新产品。相信我们优质的产品、优良的服务、优惠的合作定能取得您的信任和满意。一、DGW-A/B大型风道拐弯导流消声器本系列消声器为国家专利产品(专利号:ZL201020292274X)。使用在地铁、矿井等大型风道,可作为ZK60、T60、IK58、ZK58、K55、70B2等各型轴流风机的配套消声器。直接安装于风道拐弯处。它采用自联组合安装,不需要土建预埋件,安装维护方便。消声效果好自身阻损小且能消除拐弯处滑流。用它代替主扇水平和垂直风道消声器,解除证环境噪声达标,节约能源、节约土建占地,降低造价。本系列消声器安装结构图如图1。AB风道断面消声器大于42dB(A)消声器造型可按风机风量由表1选定订货。除表列规格外,尚可根据用户要求进行非标设计制造。
