Manual pneumatic two-way non pressure damper

  Manual pneumatic control two-way non pressure damper | installation instructions for balanced non pressure damper introduction the use frequency of pneumatic full-automatic balance damper in major coal mines is increasing
People pay more and more attention to convenience and safety
As the saying goes, good and evil depend on each other
Pneumatic full-automatic balance damper brings convenience to people
At the same time, if it can be used without maintenance, it is easy to have some small problems, such as no door response when passing people or cars, and the mine car crashes the damper, Difficulty in opening the door leaf, etc
We should understand the cause of the fault in time and solve it as soon as possible to avoid unnecessary losses

Choose the right one instead of the expensive one
The non pressure damper can be divided into high polymer materials to play the role of flame retardant and antistatic
The commonly used Q235 steel plate material can withstand high wind pressure, and the bamboo type is more safe against corrosion and moisture

The damper is divided into groups, and one group is divided into two (1 set)
The width and height of the air door are the dimensions of the clear door, i
e
clear width and clear height
It is a double leaf opposed air valve, one group has 2 channels, and each channel has two air valves
The door is equipped with a rocker linkage control system, which can easily open two air doors without resistance

The pneumatic full-automatic balance damper passes through people or the car without door or response: This is really a depressing news, which delays the production and makes the working atmosphere worse
What should we do? In this case, we need to check ourselves first
Why is the damper unresponsive when passing the car? Is the sensor controlling the opening of the damper inoperative? When the sensor is normally powered on, the red light stops and the green light goes
If the light doesn't go on, it means that the sensor is broken
This sensitive accessory really can't be guaranteed to last a lifetime, but it doesn't matter
We will replace it for free within a year

It is difficult to open the door leaf: we all know that the coal dust is flying in the underground environment of the coal mine
The coal dust is everywhere
Our door shaft will suffer a lot
If we clean it up every other time, it is OK to inject oil
If we only inject oil and do not clean it up, it will be difficult to open the door leaf because of the sticky dust of the oil
It will be absorbed in some accumulation and drilled into the door shaft for a long time
In this case, it is only necessary to remove the slime
