The self-tight rotary vane damper is a quick opening and closing and sectional adjustable damper specially developed for realizing non-stop wind down. The self-sealing rotary vane damper is used as the regulating damper of the main fan. It has the characteristics of high automation, fast switching speed and uniform force, and flexible opening and closing. It can effectively avoid the damper with the opening and closing of the valve and the accident. It is mainly composed of 46 blades (depending on the size of the duct section), door frame and actuator. The inside of the blade has shaft and steel structure support, and the outside is covered with stainless steel, which has high strength and corrosion resistance. The door frame is made of high-strength alloy steel, followed by heat treatment, anti-corrosion and other processes, sealed, flexible and corrosion-resistant. The actuator can choose hydraulic drive and motor drive, especially hydraulic drive. It has high execution precision and stable system. It can realize automatic, manual, electric and non-electric, on-site and remote three opening and closing modes. It is currently the preferred mode for each mine. . For the first time in the system, the patented product of the main fan regulating damper is hermetically sealed. The adoption of this technology product can completely solve the problem of air leakage of the damper, improve the operating efficiency of the fan, and save considerable electricity expenses. As the main provider of ventilation, there is a close relationship between the performance and working efficiency of the main fan and the gas content of the mine. When the fan is started, the magnitude and duration of the starting current are related to the wind resistance.
1.Vertical opening and closing mold and in-line screw injection for easyinlay and injection molding.
2. Double sliding plate with two lower moulds sliding out left and right, taking the product and arranging the inserts without taking up the forming time.
High efficiency, Energy-saving and high precise proportional pressure and flow variable displacement pump system make the out of the hydraulic system matching the required power for entire machine operation without loss of high pressure throttle and overflow energy. As comparedwith constant displacement pump, t saves power by 30%~60%.A motor with same power may be fitted with an oil pump of bigger displacement and thus accelerates the speed of machine.Besides, the low oil temperature will prolong the service life of sealing elements.
