SWM type pressureless damper wuli dongda factory direct sales

I feel that sometimes there is no point in communicating with others. It will be different from what you think in your heart. When others hear it, it will have a different taste in their ears, which will cause misunderstandings. What people know best is themselves. Sometimes people's emotions are actually a manifestation of their own inability to digest them. If you are lucky enough to find someone to explain, if you are unlucky you may just give others another source of conversation and make you even more confused.
Type pressureless damper
Type pressureless damper uses
Type pressureless damper (pressure balanced damper) is mainly used for each section between the inlet and return air tunnels and the main inlet and return air tunnels in coal mines. The contact alley is an updated product of the currently used damper.
There are fully transparent and ordinary types.
Performance characteristics of pressureless damper
. Small opening force. The opening force has nothing to do with the wind pressure in the tunnel;
. The damper can automatically close after people or vehicles pass by;
. Bi-directional air leakage sealing The volume is small;
. 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 pass when the mine car passes. The side of the mine car collides with the damper striker to open the damper, eliminating the need for manual door opening;
. When the minecart loses control, the damper can be opened by the side of the minecart with the impact of the damper striker. It will not cause damage to the damper;
. The structure is simple and easy to maintain.
Type pressureless damper mechanical interlocking device
Install the B-type damper mechanical interlocking device between two dampers. When one damper is opened, the other damper cannot be opened, thereby realizing the interlocking of the two dampers.
