Changzhou Chang Heng Deyu Powder Integrative Systems, Inc., a leader in pipeline custody transfer, focusing pneumatic conveying fifteen years, set design, development, production and manufacturing as one of the research-based technology company, Main: pneumatic conveying, weighing and packing, Ingredients packaging systems. Description: XZJ series rotary air lock valve 4. The factors affecting performance impeller unloader (1) leak: Because the feed side and discharge side of the discharge of the pressure difference, the leakage through the gap and the impeller Cell with high-pressure air into the rise, will hinder the smooth material particles into the stripper - cell, resulting in the discharge by the fill factor and capacity reduction, while also accelerating the discharge internal component wear. Reverse flow through the unloader large spills, but also to reduce the flow of gas through the transfer line, transmission speed decreases, the oil additive delivery system, which is likely to lead to the deterioration of transport conditions and reduced productivity. When the leak is serious, even cause pipeline blockage. For the system to normal and stable transportation, petroleum additive delivery, in the selection of the fan air flow must be considered to have more production, energy consumption and this means that the system should also be increased. Thus, the oil additive delivery program, leak affecting unloader and pneumatic conveying system performance must be given the first question, the design should be seriously considered. Unloading is usually the amount of leakage of up to 15% to 50% of the total air volume of the fan.
