Changzhou Chang Heng Deyu Powder Integrative System Co., Ltd., the main project: pneumatic conveying, weighing packaging, ingredients delivery system Description: DMP DMP automatic batching system Description of batching system main components: raw materials storage silos, single screw or twin screw feeder, the star is expected to spin valve, closed electromagnetic vibrating feeder, feeding high-precision flow control valve, four types or conical metering hopper, high torque closed doors and PLC electric discharge control section and so on. Changzhou Chang Heng Deyu Powder Integrative Systems, Inc., a leader in pipeline custody transfer, bauxite conveyor systems, pneumatic conveying dedicated fifteen years, bauxite transportation, design, development, production and manufacturing as one of the research-technology enterprises, the main Camp: pneumatic conveying, weighing packaging, ingredients packaging systems. Description: XZJ series rotary air lock valve (2) the number of blades: the right to determine the number of impeller blades to reduce leakage, improve performance unloader is also critical, bauxite transportation equipment, in general, six blades During operation of the impeller, to ensure that each side of the inlet and discharge opening between the at least one blade effectively functions as a labyrinth seal; eight impeller blades are at least two blades, 10 impeller blades least three blades can play the role of the labyrinth seal. Starting from the consideration of pressure leakage limit, the blades of the impeller 10 applies pressure to 50 ~ 100kPa (gauge pressure), the pressure applied to the blade 8 to 50kPa, 6 blades to apply pressure to 20kPa. For high-vacuum pumping system, bauxite transportation project, unloader impeller operation should guarantee from the inlet to the discharge port of each side of the at least two blade to maintain contact with the housing. Certainly not enough to play a number of blades is too small leak effect, the number is much smaller angle between the blades, the blades form of Geocell narrowed, which may make the material more difficult to fall down from the impeller, and would prevent the more into and out of large pieces of material. For good fluidity powder materials and when seals require a higher number of leaves may be more, but up to not more than 10.
