主煙道底層有一補風口。其原理是通過抽油煙機將煙氣推入次煙道中，用抽油煙機推動力和油煙溫度上浮力使油煙上升一段距離后再進入主煙道排出屋面，外加不銹鋼煙道裝飾板，煙道口可改入吊頂內，如果是中式煙機由于煙道導管外一般無裝飾板，則煙道口需改在吊頂下適當位置，以便煙道導管經裝飾板或從煙機吊柜內同煙機連接。
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.
一般來說新開餐廳時都有很多、廚具公司的業務員來恰談業務，其中很多業務員甚公司本身都不具備這方面的知識，往往跟據經驗來設計，而整個工程卻達不到所需要求，濟南通風管道的設計和安裝不合理，往往會造成廚房排煙不通暢，直接影響油煙凈化器的使用，所以我們平時在給廚房安裝設計油煙機的時候，一定要注意油煙通風管道安裝的事項。請通風管道廠家前來安裝。油煙管道在安裝的時候需要從多方面的角度考慮，注意每個細節方面的安裝布置。
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.
以風管結構的革新為特征的共板法蘭銜接新工藝及其設備的應用，推進了金屬風管加工技術的科學開展。傳統的風管管段之間的銜接是將角鋼或扁鋼法蘭與管端采用翻邊、鉚接或焊接辦法固定后，再用多個螺栓把管段銜接的工藝辦法。共板法蘭風管銜接新工藝是采用滾壓成形原理在風管兩端滾壓出法蘭外形，再經過法蘭角碼和法蘭夾將風管管段組合銜接的一種新型工藝。
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.
風管加工的主要工序是咬口加工和法蘭制造，因角鋼(扁鋼)法蘭制造費工、費料、加工周期長、質量環節多等緣由，不斷成為通風空調系統施工效率和質量的主要要素。以風管本體自成法蘭替代角鋼(扁鋼)法蘭的共板法蘭風管新工藝及其設備因工藝特征突出，一經面世，便受到本行業設計、施工、驗收相關單位和人員的肯定和采用。
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.jzfckj.net
