Overview of pressureless damper
Pressureless dampers (pressure balanced dampers) are mainly used in each contact lane between the inlet and return air tunnels and the main inlet and return air tunnels in coal mines. The pressureless dampers are an updated product of the currently used dampers.
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 pressureless damper
Under manual operation, when the mine car needs to pass the damper, manually press the door opening control button, the door opens, and door B closes at the same time, and the two doors open and close at the same time. , also accompanied by a voice prompt signal. Similarly, when the door closing control button is pressed, the door closes and door B opens.
Performance characteristics of pressureless damper
. 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
3. Two-way sealing , small air leakage
. Locking can be realized between the two dampers
. The damper opens and closes smoothly without impact, safe and reliable
. The striker type pressureless damper can be used when the mine car passes. The damper is opened by the side of the mine car squeezing the damper striker, eliminating the need to manually open the door
. When the minecart is out of control, the damper can be opened by the side of the minecart squeezing the damper striker. When the damper is opened, it will not cause damage to the damper
. The structure is simple and easy to maintain.
