Learn YJD-A-type star discharge structure is composed of a rotor with a number of blades of the impeller housing, seals and reducer, motor and other components. First, the star dust unloading valve YJD and lower flanged base is square or round, can also be selected by the user. Second, when the upper silo filling material by weight fall in the gap between the blades, with the rotation of the blades in the lower discharge, therefore, star dust unloading valve can be quantitatively and continuously discharge. Third, wear closed impeller rotor of this type of star dust unloading valve is characterized by a rotor blade ends lining polyvinyl fluoride seal, to ensure that the ends of the blades have good contact with the inner wall of the shell, and can easily adjust the blade after wear ends, so that it remains in good contact with the inside of the housing, the air lock has better performance. Four, YJD-A star dust unloading valve used in pneumatic output system, the pressure output system or negative output system, star dust unloading valve YJD-A can be evenly and continuously to the conveying tube feeding, in order to ensure air force Gas output tube, solid stable, so that the pneumatic conveying can work, same time, but the ash discharge valve on the lower pressure air lock cut off and play a role. Therefore, star dust unloading valve YJD-A is a pneumatic conveying system is an important component commonly used. Fifth, the temperature conveying material temperature type it up to 280 degrees at both ends of the bearing and impeller has a certain isolation, ultra-fine powder to prevent contact with the bearing. Temperature high temperature type discharging valve delivery of materials up to 500 degrees, using sprocket connection, reducer and cinder valve housing having a certain distance. Six, star dust unloading valve YJD-A system can be used in the collection of materials, as the silo discharging valve. Star dust unloading valve is currently the most advanced discharging device, commonly used in dust removal system as one of the important equipment dust removal system, which is particularly suitable for dust, small particles of material, by environmental protection, metallurgy, chemical industry, food, cement , roads, drying equipment and other industries to select the best projects. YJD-A star-shaped cinder valve Features 1) by using planetary rotation principle, the input and output on the same axis, but also directly connected with the motor body is unique, and therefore compact shape beautiful novel, small size and light weight. 2) smooth and reliable operation, low noise, less failure, long life, ductile iron teeth engaging member and bearing steel. Good performance, high abrasion resistance. 3) bearings, gear box, away from the body, to avoid the impact of high temperature dust, front cover sealing performance, prevent dust leakage, extending motor parts, lifetime lubrication system. 4) The machine has strong overload capacity, impact resistance, small moment of inertia for frequent start and turn anyway. 5) Users For special specifications, motors, sprocket and other discharge, can contact with the factory, the system can do. Star discharge Botou our production base, we have a professional technical staff, has a one-stop production line of production, with three bags of sale, welcome to visit the factory inspection!
