Classification :company newsDATE:2016-11-04

Ventilation ducts have the following four connection types:

1, hoop-type connection: mainly used for steel circular ventilation ducts and spiral duct connection, the first of each tube ends of the roll out of the tendons, and make one end reduced to small mouth. Installed by the air direction of the small mouth into the mouth, the outside with a steel hoop to the two ends of the drum hoop tightly connected, and finally with a bolt to wear in the middle of the earrings fixed tight.

2, plug-in connection: mainly for rectangular or circular duct connections. First make the connecting pipe, and then insert both sides of the duct, and then pull the rivet to tightly fixed.

3, cutting-type connection: mainly used for rectangular duct connections. Different forms of cuttings are inserted into both ends of the duct and then compacted.

4, hose connection: mainly used for air duct and components (such as radiators, static pressure side of the outlet, etc.) connected. Installation, the hose at both ends of the tube set in the connection, the use of a unique design of the filter media, not only has good ventilation performance, but also improve the effective filter area, long service life, dust removal efficiency. The filter element is automatically cleaned, eliminating the need to stop the machine and other operations. When the cartridge surface saturation resistance reaches a certain allowable value, the automatic cleaning function is turned on, and in the host work process in turn for each filter backflush cleaning to ensure that the dust is always in good working condition.
