Pressureless damper manufacturer direct sales Pressureless damper Specifications Pressureless damper performance: >Introduction to pressureless damper
Pressureless damper (pressure balanced damper) is mainly used in coal mines between the inlet and return air tunnels and the main inlet and return air lanes. In a communication lane, the pressureless damper is an updated product of the currently used damper.
Pressureless dampers are available in fully transparent and ordinary types.
: >Pressureless damper door body structure
The pressureless damper door body is mainly composed of door frame, door leaf, sealing baffle and sealing material, etc., and is sealed by felt peripheral bonding. The door frame is made of welded steel as shown in the picture (facing the direction of wind pressure).
: >Working principle of the pressureless damper
Under manual operation, when the mine car needs to pass the damper, manually press the door open r control button, the door will open, and door B will close at the same time, and the two doors will open and When closing, there is also a voice prompt signal. Similarly, when the door close r control button is pressed, the door closes and door B opens at the same time.
: >Performance characteristics of pressureless dampers
. The opening force is small, and the opening force has nothing to do with the wind pressure in the tunnel
. The damper can automatically close after a person or vehicle passes by
. Two-way Sealed, with small air leakage
. Locking can be achieved between the two dampers
. The damper opens and closes smoothly without impact, safe and reliable
. When the mine car passes, the impact-rod type pressureless damper will The damper can be opened by the side of the mine car squeezing the damper striker, eliminating the need to open the door manually
. When the mine car is out of control, the damper striker can be opened by the side of the minecart squeezing the damper striker. Opening the damper will not cause damage to the damper
. The structure is simple and easy to maintain.
