Mine automatic throttle, coal automatically without pressure damper, electric throttle without pressure, without pressure damper pneumatic, manual without pressure throttle, closed doors, blast doors manufacturer Jinan Dongshan Mine Equipment Co., Ltd. (0531--89004695) is an advanced equipment strong technical force, strict quality management of mine throttle enterprise entities, because the use of materials, exquisite workmanship and the trust of our customers. With the mine now continue to develop science and technology, in order to achieve a well-developed science and technology, intelligent modern coal business requirements, rely on modern science and technology to improve efficiency, promote sound and rapid development of the mine, which can strengthen the management promote the information technology industry, the pace of building the mine further improved. No pressure damper is a summary of the basis for the existing domestic non-pressure damper structure and technical performance of the research and development, the structure is simple, durable, and closed steady, safe and reliable. With these advantages, the use of which in peacetime, just a little maintenance, you can rest assured that use. Usually in the mine will be a lot of customers to save costs in order to achieve complete mechanical locking manual throttle opening. But for many of the roadway over the tub must have supporting automatic throttle control system, must automatically open dampers. So how to achieve the throttle is automatically open it? Tunnel walls two ends of the throttle infrared sensors were installed at both ends of the damper forming detector line, when the pedestrian or vehicle entering the tunnel by either party, the sensor automatically detect and provide a signal to the control device, when the main entrance was through A The sensor sends a signal, A main entrance of the power source is energized, open A damper is equipped with a sensor on the throttle, close, close state detection damper (This signal may be communicated to ground control room, in order to easily detect the damper closed), the anti-door usually normally open. When you open the A door, sound and light alarms get a trigger signal, alert warnings "throttle open, please pay attention to safety," and pass the red light flashes, B door audible alarm device will prompt "in front of the throttle open, Please you later "red light .B doors fitted with locking (Depending on the installation option), in order to prevent both doors are open and affect the safety of coal mine, after a suitable delay (which can be set according to need), A main entrance automatically shut down after the closure in place until the sensor detects, warning voice and the red light turned off, the green light throttle and B .A reverse reverse throttle is fully open .. We have the spirit for the sake of attitude, development, production, marketing, sale, transport one-stop service, Jinan Dongshan Mine Equipment Co., Ltd. cordially invites you to the company, to witness its production processes, combined with your guidance allows you a lot of satisfaction.
