The function of mine two-way non pressure air door and mine anti ground pressure air doo

  The role of mining two-way non pressure damper and mining anti ground pressure damper everyone knows that mining two-way non pressure damper and mining anti ground pressure damper adopt the pressure balance principle
Each damper is a double leaf steel door frame, which is mainly composed of door frame, door leaf, balance structure and counterweight
Therefore, we must first prepare items for installation: spanner, level gauge, hanging wire, log and gasket
During installation, the damper shall be vertical and flat without distortion, and shall be flat when closed
First, dig pits at appropriate positions on both sides of the track, and then level; Then put two crossbeams in the roadway to put the door frame, and fix the door frame with bolts; Then set up the door frame, adjust the left and right distance, level, and the two door frames are in a vertical plane; Build the wall, fix the guide wheel in the wall at a proper position, and then clamp the door beam with wood; After the door wall solidifies, install the door leaf, balance structure, guide wheel, handle, bucket and other accessories, and then close the door for test until it is tightly closed, and then use a wrench to lock the nut; Install the oil cylinder on the door and connect the oil cylinder and the pump station with rubber hose; Then connect the wires according to the prompts of the wiring diagram, and then debug the reverse flow valve; Start the sensor and test whether the fan starts normally
By the way, the fasteners on the door must be oiled and maintained regularly so that the damper can be used for a long time

So what is the function of mine two-way non pressure damper and mine anti ground pressure damper? In general, the mine two-way non pressure air door and the mine anti ground pressure air door are used in the mine connecting roadway to block the air flow
Do not mix clean air with dirty air to block the airflow
Therefore, the sealing effect of the non pressure damper is required to be obvious, so the quality of the supporting sealing strip is better, and the sealing effect should be obvious
All in all, we strive for good quality and good results
