China Positive pressure conveying manufacturers - Allway

        The positive pressure conveying system uses pneumatic conveying to convey powder materials, which can be arranged according to the specific terrain to achieve centralised, dispersed, large height and long distance conveying, the conveying process is not affected by the weather conditions and can ensure that the materials are not affected by moisture, which is conducive to production and environmental protection, with high efficiency, energy saving and environmental protection. The positive pressure conveying system is widely used in the electric power, metallurgy, petrochemical, plastics, food, building materials and hydropower industries.

　　The conveying principle of positive pressure conveying system.

　　Due to the role of pressure, materials from the sending tank into the conveying tube, compressed gas through the solenoid valve a certain frequency of opening and closing the formation of pulse gas flow (gas knife), with the gas knife pressure is greater than the sending tank pressure will be cut into material bolts, relying on the static pressure difference before and after the bolts as a driving force, the material will be pushed forward to reach the separation device to implement the material gas separation, the material falls into the silo, gas discharge into the atmosphere, to achieve transport.

　　Positive pressure conveying system features.

　　1、System has high pressure and small gas consumption;

　　2、Low flow rate but large conveying capacity, almost no effect on material quality;

　　3、The control system is automated, with high requirements for various electrical components;

　　4, can be multi-point feeding and multi-point unloading;

　　5, large conveying capacity, suitable for short or medium distance of pneumatic conveying.
