济南通风管道加工加固全过程中，应依据管道工作压力尺寸、管经尺寸挑选相对应的加固方法，加固方式的挑选，对通风管道的使用寿命有关键性的危害，一般情形下，可使用下列几类方法开展加固：
In the whole process of processing and reinforcement of ventilation pipes in Jinan, the corresponding reinforcement methods should be selected according to the working pressure size and pipe diameter size of the pipes. The selection of reinforcement methods is critical to the service life of ventilation pipes. Generally, the following methods can be used for reinforcement:
(1)加强抱合的方式
(1) Strengthen the way of holding
常用原料也是轻钢龙骨隔墙一般用以较独特的管道加固，关键有900弯头，三通管和闷头管等。
Common raw materials are also light steel keel partition walls, which are generally used for more unique pipe reinforcement. The key points are 900 elbows, tees and bulkhead pipes.
(2)吊线加固
(2) Suspension wire reinforcement
该技术规定选用钢色、防水套管等原材料进行加固，正压力加固规定在500pa下列。
The technical regulations use steel color, waterproof casing and other raw materials for reinforcement, and the positive pressure reinforcement is specified below 500pa.
(3)加强架构法
(3) Strengthening the framework method
这类加固方法可以用轻钢龙骨隔墙进行法开展加固。对运送易燃性性、易燃易爆物品气体的碳钢板风管，在风道连接法兰片口要安装接地线，并与放电接地系统网连接。
This kind of reinforcement method can be carried out by using light steel keel partition wall. For the carbon steel plate air duct transporting inflammable, inflammable and explosive gases, the grounding wire shall be installed at the opening of the connecting flange of the air duct and connected with the discharge grounding system network.
当风管与除尘设备、加温设备等连接前，应待设备安装完成后，按实际测绘工程的施工图纸进行预制件构件和安装。
Before connecting the air duct with dust removal equipment and heating equipment, the prefabricated components and installation shall be carried out according to the construction drawings of the actual surveying and mapping project after the equipment installation is completed.
此外在一些加工厂、生产线有大批量的尘土，须特别的除尘器设备。螺旋风管可用以风大量管道总流量。在挑选厨房机器设备时，可以按照自身须的情形和应用需要完成挑选。选择时须要留意相对应的状况，由于厨具设备类型许多，须留意的小细节也比较多，应用时出差错会危害制成品的实际效果。因而，在挑选厨房机器设备主要用途时要需注意下列一些层面。
In addition, there are large quantities of dust in some processing plants and production lines, so special dust collector equipment is required. Spiral duct can be used to wind a large amount of total pipe flow. When selecting kitchen machinery and equipment, you can complete the selection according to your own needs and application needs. When choosing, you should pay attention to the corresponding situation. Because there are many types of kitchenware and equipment, and there are many small details to pay attention to, errors in application will endanger the actual effect of finished products. Therefore, when selecting the main uses of kitchen machinery and equipment, we should pay attention to the following aspects.
