What is a positive pressure delivery system?

In industrial production, some such as plastics, rubber, pharmaceutical and other powder and granular materials in the processing of the production process, will use the positive pressure transport system for the transport of materials, positive pressure delivery system can be applied a wide range. But for some users, do not understand what is a positive pressure delivery system? Hengrong technician for the following details:

Positive pressure delivery system is the use of positive pressure air source as a transmission medium, the material at high speeds to disperse suspended state in the pipeline for transmission. General use of the gas source has centrifugal fan, Roots blower, air compressors. The delivery pressure varies from a few kilopascals to a few hundred kilopascals depending on the conditions. Positive pressure transmission for dynamic pressure delivery.

Positive pressure transmission system advantages Features:

1. The use of gas dynamic pressure, the material at a higher speed in the pipeline in advance (15m / s-30m / s), the transmission pressure along the pipeline gradually reduced;

2. It can realize multi-point simultaneous feeding and multi-point discharging, high production efficiency;

3. Conveyor capacity, especially suitable for short distance or medium distance pneumatic conveying;

4. Used in closed-loop system, do not increase the gas buffer device, easy to control;

5. Positive pressure conveying system has high reliability, and it is easy to maintain in the continuous conveying and conveying flow, conveying pressure and conveying speed, material gas ratio.
