Precautions for maintenance of duct production line

The normal operation and operation of the duct production line can not be separated from the normal operation of the air duct machine. Therefore, in order to ensure the normal operation of the machine, and ensure that the daily air duct production does not stop failure, it is necessary to maintain and maintain the pipe production machine. Comifo, the duct production line manufacturer, said that the maintenance of the duct line should be carried out from all aspects

1, for the duct cleaning system, flexible pipe material requirements are relatively high, must have dustproof, airtight, smooth and so on. The connection between the pipe and the duct equipment must be more strict. And the appearance of the tuyere requirements are more stringent, the quality should be qualified, border and blade to be smooth and smooth.

2, in the production of air valve, there should be signs of opening and closing. Multi blade valve blade joints need to overlap consistent, and wheelbase deviation in less than 1mm. For flexible pipe, the tightness should be suitable, the length should be within the scope of construction specifications, and meet the design requirements. Cracking and twisting are not allowed.

3, the hood production requirements, the specific performance of the complete rules, keep balance of shape, size deviation within 2mm per meter. Fire valve rotating parts need corrosion resistance is very strong, and its close to tight airtight.

Structure and function of fire damper

What are the structures and functions of fire dampers?

On the air duct of the air conditioning system, the purpose of the installation of fire dampers is to quickly cut off the air flow in case of fire, so as to prevent the fire from spreading. The fire valve diagram, when the fire duct, influence by ambient temperature and temperature, so that when the fire duct reaches a certain temperature, the fusible film fuse, the valve plate connected by the original fusible film and then fusible film closed stop airflow through off. In order to stop supplying air to the system and to install electrical signals and interlocks on the fire damper, the valve plate will signal when it is closed so that the fan will stop running.

Fire valve installation position:

(1) the main air duct on the air outlet of the air conditioning equipment (fresh air unit, unit, etc.).

(2) air passage through fire compartment.

(3) the air passage passes through the expansion and subsidence joint of the building structure.

(4) air passage, in unavoidable circumstances, through flammable workshops or rooms. The fire valve can be divided into self tipping, fire control valve type, manual reset, fusible film movement temperature is 70 DEG C.

The application of TDF flange machine in ventilation system

In recent years, the use of air duct as an important part of the ventilation system of the central air conditioning system has been increasing each year, and the production process of the air conditioning system has been increasing. And the advantage of TDF flange machine makes its application more and more extensive. The TDF flange air duct machine is also known as flangeless duct, and its production is faster, more convenient and less air leakage rate than the traditional rectangular duct. Its advantages are to save materials, reduce investment, reduce energy consumption, and save operating expenses, which are popular with construction enterprises.

Ventilation and air conditioning is to make indoor and outdoor return air treated as temperature, humidity, freshness air to meet the requirements of the environment, what doesn’t meet the requirements of the temperature, humidity, freshness air will be returned and treated or exhaust back  into the atmosphere. This process will be completed through ducts, which are mostly made of galvanized sheets.

Duct without flange connection construction technology is to keep the flange connecting duct and accessories cancelled, instead of direct occlusion, and middleware bite, such as pieces of auxiliary clamping way complete duct of lateral connection. Because no flange connection duct joint are usually simpler than flange connection, and together with the joint auxiliary parts no flange connection without auxiliary parts (some) weight is lighter, simple or standard parts can be used for batch production, can not only save a large number of steel, but also greatly simplify the construction process, improve the productivity, the experimental determination, no duct sealing flange connections is also better than the flange connection duct.  As TDF flange is with the same sheet metal plate with the duct, it seems to be designated as a kind of flangeless duct. It is widely used in the word and becomes more and more popular.

Comifo has been working hard for many years to provide competitive products for the majority of users. With excellent quality, novel design, reasonable price and perfect after-sales service, we have won the full trust and praise of our customers. It is a professional co-board flange duct production line manufacturer.
