How to choose the correct conveying equipment in pneumatic conveying system
? ? ? In pneumatic conveying systems, conveying equipment is essential, so how to choose the appropriate conveying equipment correctly.
? ? ? Pneumatic conveying is divided intoDense phase (solid phase) pneumatic conveying, dilute phase pneumatic conveying,Dilute phase pneumatic conveyingIt is divided into positive pressure and negative pressure conveying, and both conveying systems require the use of conveying equipment
? ? ? Firstly, let's talk about dense phase pneumatic conveying. In dense phase pressure conveying systems, compressed air is used as the air source to blow materials. The pressure inside the pipeline is greater than atmospheric pressure, so the conveying equipment is selected as a bin pump or AV pump to complete the conveying of materials. Bin pumps and AV pumps have the characteristics of high pressure resistance, low air consumption, good sealing, and long conveying distance. Suitable for conveying various powder materials.
? ? ? Dilute phase positive pressure pneumatic conveying is a blowing conveying method, using Roots blower as the gas source for conveying. The conveying equipment can choose wear-resistant rotary feeders, material sealing pumps or continuous conveying pumps as conveying equipment. The material sealing pump can transport without a power source during the conveying process, and has good conveying effect for powder materials; Continuous conveying pumps are suitable for short distance powder pneumatic conveying systems; The rotary feeder includes but is not limited to the advantages of the above two, and is widely used for conveying powders, particles or irregular materials. It has the characteristics of good sealing, wear resistance, high temperature resistance, anti jamming, anti-corrosion, etc., and is widely used by users.
? ? ? The dilute phase negative pressure pneumatic conveying is a suction conveying method, which also uses a Roots blower as the gas source for conveying. During the conveying process, a wear-resistant rotating feeder is installed in conjunction with a negative pressure separator to continuously transport materials into the silo. The negative pressure pneumatic conveying system can be used for materials in the silo or in bulk on the ground. The conveying process is dust-free and highly sealed.
