I.  Pressureless Dampers for Mining

1.Overview

        Mining pressureless dampers have made a number of, No.: ZL201320673493.6, ZL201420080758.6, ZL201620504125.2, ZL201620504194.3. Our company mass production of various kinds of pressureless dampers, after a few years of product improvement and process improvement, the production of the pressureless dampers regardless of the appearance or the quality of the inner have reached the domestic leading level. The appearance and inner quality of pressureless dampers have reached the leading level in China. We have developed intelligent controller and intelligent locker for pressureless damper, which can control the damper intelligently. The intelligent controller is equipped with 485 and Ethernet communication interface, which can monitor and control the pressureless damper remotely.

        Pressureless dampers are connected by two doors with equal area through connecting rods, the opening direction of the two doors is opposite, because of wind pressure in the same direction, one door opens and the other closes, because of equal area and wind pressure, the force on the two doors is equal in size and direction, and the distance of the two doors from the rotating axis is also equal, so the opening torque of the damper and the closing torque are equal, and the damper is in the state of force equilibrium, so it is not necessary to use much thrust or thrusting or thrusting or thrusting or thrusting. Therefore, the door can be opened with little push or pull. The two dampers use locker to ensure that the dampers can not be opened at the same time to realize locking, our company has developed a reliable, simple and practical intelligent mechanical locker, but also developed a pneumatic locking device, electric locking device to adapt to pneumatic and electric dampers.
