主烟道底层有一补风口。其原理是通过抽油烟机将烟气推入次烟道中，用抽油烟机推动力和油烟温度上浮力使油烟上升一段距离后再进入主烟道排出屋面，外加不锈钢烟道装饰板，烟道口可改入吊顶内，如果是中式烟机由于烟道导管外一般无装饰板，则烟道口需改在吊顶下适当位置，以便烟道导管经装饰板或从烟机吊柜内同烟机连接。
There is a make-up air outlet at the bottom of the main flue. The principle is to push the smoke into the secondary flue through the range hood, use the driving force of the range hood and the upward buoyancy of the oil smoke temperature to make the oil smoke rise for a certain distance, and then enter the main flue to exhaust the roof, with stainless steel flue trim panels, and the flue opening can be changed into the ceiling. If the Chinese flue is generally without trim panels outside the flue duct, the flue opening needs to be changed to a proper position under the ceiling, So that the flue duct can be connected with the flue through the decorative plate or from the flue hanger.
一般来说新开餐厅时都有很多、厨具公司的业务员来恰谈业务，其中很多业务员甚公司本身都不具备这方面的知识，往往跟据经验来设计，而整个工程却达不到所需要求，济南通风管道的设计和安装不合理，往往会造成厨房排烟不通畅，直接影响油烟净化器的使用，所以我们平时在给厨房安装设计油烟机的时候，一定要注意油烟通风管道安装的事项。请通风管道厂家前来安装。油烟管道在安装的时候需要从多方面的角度考虑，注意每个细节方面的安装布置。
Generally speaking, when a new restaurant is opened, many salesmen from environmental protection and kitchen appliance companies come to talk about business. Many of them, even the company itself, do not have this knowledge, and often design based on experience. However, the entire project cannot meet the requirements. The design and installation of ventilation pipes in Jinan are unreasonable, which often causes the kitchen to smoke unobstructed, and directly affects the use of the lampblack purifier, Therefore, we should pay attention to the installation of lampblack ventilation pipe when installing and designing the lampblack ventilator in the kitchen. Please install the ventilation pipe manufacturer. The installation of lampblack pipe shall be considered from various perspectives, and attention shall be paid to the installation layout of each detail.
以风管结构的革新为特征的共板法兰衔接新工艺及其设备的应用，推进了金属风管加工技术的科学开展。传统的风管管段之间的衔接是将角钢或扁钢法兰与管端采用翻边、铆接或焊接办法固定后，再用多个螺栓把管段衔接的工艺办法。共板法兰风管衔接新工艺是采用滚压成形原理在风管两端滚压出法兰外形，再经过法兰角码和法兰夹将风管管段组合衔接的一种新型工艺。
The application of the new technology and equipment of the common plate flange connection characterized by the innovation of the air duct structure has promoted the scientific development of the metal air duct processing technology. The traditional connection between air duct sections is the process of connecting the pipe sections with multiple bolts after the angle steel or flat steel flange and the pipe end are fixed by flanging, riveting or welding. The new process of connecting common plate flange air duct is a new process that uses the rolling forming principle to roll out the flange shape at both ends of the air duct, and then combines and connects the air duct sections through flange corner pieces and flange clamps.
风管加工的主要工序是咬口加工和法兰制造，因角钢(扁钢)法兰制造费工、费料、加工周期长、质量环节多等缘由，不断成为通风空调系统施工效率和质量的主要要素。以风管本体自成法兰替代角钢(扁钢)法兰的共板法兰风管新工艺及其设备因工艺特征突出，一经面世，便受到本行业设计、施工、验收相关单位和人员的肯定和采用。
The main processes of air duct processing are seaming processing and flange manufacturing. Because angle steel (flat steel) flange manufacturing is labor-intensive, material consuming, long processing cycle, and many quality links, it has become the main factor of the construction efficiency and quality of the ventilation and air conditioning system. The new process and equipment of common plate flange air duct with self formed flange of air duct body instead of angle steel (flat steel) flange have been recognized and adopted by relevant units and personnel in design, construction and acceptance of the industry as soon as they came out due to their outstanding process characteristics.
Shandong Shenhe Ventilation Equipment Co., Ltd. focuses on the production of Jinan ventilation pipe processing and other related products. For more highlights, please click our website: http://www.1nightescorts.com
