(Summary description)Positive pressure conveying system manufacturers: The positive pressure dense phase pneumatic conveying system uses the compressed air source as the conveying source. The medium conveying materials in the pipeline at low speed, sand dune state, fluidization or condensation state is called positive dense phase conveying. Usually, the air source is an air compressor or a high pressure Roots blower. According to the conveying characteristics, the system can be divided into positive pressure dense phase dynamic pressure conveying and positive pressure dense phase plug conveying. Dense phase dynamic pressure conveying is the conveying method of materials in pipelines in medium and low speed sand dunes or fluidized state; the way of conveying materials in pipelines at low speed in agglomerated state is called dense phase plug conveying.   Characteristics of Positive Pressure Dense Phase Pneumatic Conveying System 1. The working pressure is high, which can realize long-distance transportation; the supercharger can realize ultra-long-distance transportation. 2. Low wear of pipes and materials due to low material transport speed. 3. The material-to-gas ratio is high, and the gas consumption is small. 4. The conveying air volume is small, and the separation of material and gas is easy to achieve. Basic parameters of positive pressure dense phase pneumatic conveying (for reference only, depending on the specific material characteristics) 1. Positive pressure dense phase dynamic pressure conveying: air source type Roots blower, air compressor. 2. Positive pressure dense phase plug conveying: air source type high pressure air compressor.   The positive pressure dense phase pulse pneumatic conveying system uses the positive pressure air source as the conveying medium, and the material advances in the pipeline at a low speed in the form of a plug. The air source used is high-pressure compressed air. According to the working conditions, the delivery pressure is generally greater than 0.5MPa. Positive pressure dense phase pneumatic conveying system Dense phase pulse conveying system is mainly suitable for granular materials or powdery materials with good fluidity. Dense phase pulse conveying can realize slow pulsation of materials in the pipeline, and is suitable for fragile, heat-sensitive and explosive materials. Features of positive pressure dense phase pulse pneumatic conveying system: 1. High working pressure enables long-distance bolt conveying. 2. Due to the extremely low material conveying speed, the wear degree of pipes and materials can be ignored. 3. The material-to-gas ratio is high, and the unit gas consumption is very small. 4. The conveying gas is small, and the separation of material and gas is easy to achieve 5. The requirements for material properties are very strict. Users are advised to use positive pressure dense phase pulse pneumatic conveying with caution. Basic parameters (for reference only, depending on the specific material characteristics). Air velocity is high. Strong delivery capacity. The conveying distance is large. Air source type high pressure air compressor.
