专注通风管道加工·排烟罩

　　1. Ventilation piping design shall be carried out according to the site, structure and environment required for installation of the ventilation pipe to ensure the practicability of the ventilation duct.

　　2、一般送排风系统和空调系统的通风管道安装，需在建筑物的屋面做完，安装部位的障碍物已涪理干净的条件下进行。

　　2, general ventilation pipe ventilation system and air conditioning system installation, should be done in the roof of a building, the obstacle of the installation part has disposal of clean conditions.

　　3、一般除尘系统通风管道安装，需在厂房内与风管有关的工艺设备安装完毕，设备的接管或吸、排尘罩位置已定的条件下进行。

　　3, general dust removal system ventilation pipe installation, need to be in the workshop with the wind pipe related process equipment installation, equipment take over or suction and dust discharge hood position has been set under the conditions.

　　4、施工准备工作已做好，如施工工具、吊装机械设备、必要的脚手架或升降安装平台已齐备施工用科已能满足要求。

　　4, construction preparation work has been done, such as construction tools, hoisting machinery and equipment, necessary scaffolding or lifting installation platform has been completed, construction section has been able to meet the requirements.

　　5、要与土建施工密切配合，应预图的安装孔洞，预埋的支架构件均已完好，并经检查符合设计要求。

　　5, to work closely with the civil construction, should be pre installed holes, the pre embedded support components are intact, and checked to meet the design requirements.

　　6、通风及空调系统管路组成的各种通风管道、部件、配件均已加工完毕，并经质量检查合格。

　　6, ventilation and air conditioning systems composed of a variety of ductwork, parts and fittings have been processed, and the quality inspection qualified.

　　1)对于比较复杂的民用建筑，在设计阶段，各工种(暖通、给水排水，供电照明与建筑)应协商好空间分隔，定出每种管道的标高范围。一般情况下不得越出给自己规定的界限。遇有个别管段要越界时应与其他工程协商。

　　1) for more complex civil buildings, in the design phase, the various types of work (HVAC, water supply, drainage, power supply lighting and building professional) should first negotiate space separation, determine the elevation of each pipe range. The general case not set himself beyond the boundaries. In case a paragraph is crossed, consult with other projects.

　　2)解决各种通风管道相碰及协调的原则，一般为：“小管让大管，有压让无压”。例如，自来水管与风管相撞，则应当自来水管拐弯。冷、热水管与下水管相碰，则应改变冷、热水管道。

　　2) to solve all kinds of ventilation pipe collision and coordination principle, generally: "let the pressure get tubular bassoon, no pressure". For example, when the water pipe is in collision with the air pipe, the water pipe should be turned. The cold and hot water pipes and water pipes together, should change the cold and hot water pipe.

　　3)施工前应设备总管的工程师，将各工种的管线，单线画在一张平面图上。每种管道用一种彩色笔。在各交点处综合其标高，看是否有矛盾之处，及时发现，将问题解决在安装之前。

　　3) the engineer of the equipment main shall, before construction, draw the lines of each type of work on a single plan. Each pipe uses a color pen. At the intersection of each of its elevation, to see if there are inconsistencies, timely discovery, the problem before the installation.

　　4)为了减少投资，节省空间，降低层高，有些敷设无坡度要求的管道，可以穿梁敷设(如自来水管道，消防喷洒干管等)。

　　4) in order to reduce investment, save space and reduce storey height, some laying pipelines without slope requirements can be laid through beams (such as water pipes, fire fighting, dry pipes, etc.).
