Adjust the product introduction of baffle damper
Damper damper take sheet stamping overall welding structure, the regulating characteristics are within the scope of the blade opening 25 ° ~ 75 °, a linear relationship between resistance coefficient and the opening, Streamlined blades, can make the air flow wake distribution improved.
Smoke damper damper used in the wind for regulating work flow in pipeline at different positions of the blades rotate 90 °, by different work flow, it has flexible rotation, adjust the advantages of good performance. The damper is the introduction of the CE technology design and production, relative or parallel adjacent blades (only for centrifugal machine entrance) movement pattern, for hot air damper, positive pressure system at shaft end bearing is equipped with sealed air connector, can access the seal air blocking leakage of hot air.
Damper take sheet stamping overall welding structure, the regulating characteristics are within the scope of the blade opening 25 ° ~ 75 °, a linear relationship between resistance coefficient and the opening, Streamlined blades, can make the air flow wake distribution improved.

The performance characteristics of damper damper
A damper baffle vane at 90 ° Angle rotation schedule scope, whole journey opening and closing time usually 50 s or less (can also be selected according to user requirements).
B damper structure for the shutters baffle type structure, designs which have external linkage, made a number of blade at the same time open or closed.
C damper blade adopts the wing shape structure, good rigidity, high strength, small resistance.
D a number of damper blade rotation is "8" form to the direction of opening or closing, opening and flow linear adjustment.
E the drive mode usually for electric drive mode of damper. Throttle valve electric device with the installation of the form is divided into: straight association-like, crank bearing (local or distant) two types of installation.
F the valve electric actuator are usually choose electromechanical integration products, with 4-20 ma analog input, output, fast, and has the torque protection and the limit switch, can be local or remote control operation, electric device also has the function of hand, electric switch for installation and maintenance.
G damper and pipeline connection mode: flange, bolt connection; Flange welding connection or pipe direct plug-in welding three connection mode.
