Product Introduction:

Dense phase storage pump pneumatic conveying system
Operating principle of positive pressure dense phase pneumatic conveying
The dense phase conveying pump is a relatively reliable dense phase dynamic pneumatic conveying equipment that transports powdered materials under high pressure (below about 1000kPa). There are two unloading methods for dense phase pumps, with bottom discharge being a commonly used method. The materials in the tank are fluidized through a conical inflatable tank, nozzle jet, or other methods; Setting a fluidized inflation plate layer at the bottom can allow the material to be discharged from the upper part of the tank, and the dispersion of the transported gas on different input planes in the tank depends on the properties of the transported material.
Positive pressure dense phase pneumatic conveying is a non continuous conveying process, equipped with inlet and outlet valves, material conveying pipelines, air input pipelines, and a standardized silo pump. Before the silo pump feeds, the silo contains the transported material, and all valves are closed.

The process of all positive pressure dense phase pneumatic conveying operations is as follows
1. Open the feed valve and exhaust valve, and the bin pump will feed at normal pressure until the level gauge announces that the bin is full and the indicator signal stops;
2. Close the feed valve and exhaust valve, and then open the high-pressure air valve to pressurize the tank;
3. When the operating pressure is reached, open the delivery air valve and discharge valve, and the material begins to be delivered;
4. The conveying end is displayed by the pressure switch, level gauge, or time relay. At this moment, the high-pressure air valve and discharge valve are closed, so that all compressed air is used to clean the conveying pipeline; Open the exhaust valve together to reduce the pressure inside the tank to normal pressure. After one homework cycle is completed, the other cycle continues.
Dense phase pneumatic conveying has the advantages of long conveying distance, low equipment noise, and long overall service life.
