Installation method of construction air duct for fire and smoke exhaust works Installation method of construction air duct for fire and smoke exhaust works Air duct can be installed in place according to the site conditions, which can be connected to the length of a piece on the ground and installed in place by hoisting method, or the air duct can be placed on the support section by section and connected section by section. The general order is the main pipe first, then the branch pipe. The riser is generally installed from bottom to top. Leveling and alignment shall be carried out after installation in place to meet the requirements specified in the design. The problems that should be paid attention to in the installation of air ducts for ventilation engineering construction: when the air ducts are connected by non flange

What should be paid attention to in the construction of ventilation ducts What should we pay attention to in the construction of ventilation ducts? The construction of ventilation ducts is a kind of air exchange equipment. It uses mechanical or natural methods to send enough fresh air into the indoor space, and at the same time, it discharges the dirty air that does not meet the sanitary requirements, so that the indoor air can meet the sanitary requirements and production process needs. The construction of ventilation projects has a very wide range of use. Today, the facilities that complete ventilation work in buildings are collectively referred to as ventilation duct equipment. Duct Equipment Split Fan

Key points for calculation of construction and installation quota of ventilation pipeline engineering Key points of quota calculation for construction and installation of ventilation duct works 1. Ventilation duct construction and components: power system: supply fan, return fan; Air handling system; Air delivery system: silencer, balance valve; Air distribution system: louver, exhaust outlet, air supply outlet Ventilation engineering construction: sheet steel, glass fiber reinforced plastic and composite. 2. Measurement principle: elbow, tee and reducer are not deducted; Special parts of the deduction valve: elbow guide vane, which does not deduct the quota of the use, manufacture and assembly during measurement; Cancel

Key points for quick installation of ventilation pipeline construction In today's building facilities, we are not unfamiliar with the construction and application of ventilation ducts. We can often see the construction of natural gas, water pipes and cable ducts in the days. However, do you know about the quick installation of pipeline devices? Let's see what the key points are for the completion of ventilation pipeline construction: 1. Operators should strictly implement the special construction plan and the disclosure of safety technical measures. 2. During the horizontal transportation or hoisting operation of ventilation pipeline construction and subordinate equipment, the operators shall be mainly crane operators

What should be done for the connection of ventilation pipe construction During the construction of ventilation pipes, the pressure drop is relatively low. As we all know, some ventilation methods should be given priority as technical measures to ensure the air quality of the working and living environment and prevent indoor environmental pollution. Next, the spiral ventilation duct has a fine seaming forming process. The mold used for its imported equipment is also a special steel structure. Even if it has been used for three or five years, the appearance of its pressing mold will remain unchanged. When Shenyang ventilation pipe air

Preparation before construction of ventilation pipeline The function of ventilation ducts is to circulate air. They are mainly used in industrial and construction projects. They are widely used in industrial equipment, workshop purification systems, hotels, shopping malls, hospitals, factories and office buildings. But what preparatory work should we do in the construction of ventilation ducts? 1、 Construction preparation (I), operation condition 1, the equipment of general blower system and air conditioning system should be completed in the building enclosure, the obstacles have been cleared, and there is no

Preconditions for ventilation pipe construction If we are careful, we can find that there are many rectangular pipes on the exterior walls of some factories. From the appearance, they are made of iron sheet. Do we know what the role of this pipe is? In fact, they are used for ventilation. Because the production operations in the factory often release some gases, some are harmless gases, but some are harmful gases, so in order to ensure the health of workers in the factory, these gases need to be discharged outside. To think about this

Main application of ventilation pipe construction At present, more and more consumers choose to construct ventilation ducts, so let's briefly understand the application of ventilation duct construction in the industry together: 1. Ventilation duct construction: supply fresh air and exhaust, exhaust harmful gases outside, and send outdoor fresh air indoors. Generally speaking, the flow of the ventilation system is very large, so it is required to use the air transmission pipeline with small resistance to save the cost and operating costs - the construction of the ventilation pipeline is applicable. Generally

What application parameters are involved in the construction design of ventilation ducts Ventilation duct construction is the general term of air supply, exhaust, dust removal and smoke exhaust system engineering. Its construction projects include the layout of pipelines and the planning devices of motors and air conditioning equipment. In order to ensure the application of the overall ventilation project, it is necessary to summarize various elements in the project planning and installation link, and use relevant parameters to make reasonable planning. The ventilation duct is an important part of the ventilation system. The purpose of the ventilation duct system planning is to reasonably arrange the air flow to ensure the use of
