The working process of the bin type pump is divided into 4 phases:
1. Feeding phase
When the feeding valve is opened, the materials fall in the pump body freely. When the rising materials in the pump body touch the level gage, the level gage gives out the full-material signal, and the feeding system is closed automatically to complete the feeding process.
2. Fluidifying and pressing phase
The air inlet valve is opened automatically, the compressed air enters the bottom of the pump body, and is diffused through the fluidized bed. With the full fluidization of the material, the gas inside the pump rises.
3. Conveying phase
When the pressure inside the pump reaches a certain value, the pressure sensor gives out a signal, the discharge valve is opened automatically, the materials on the fluidized bed are conveyed, the materials inside the pump decrease gradually. In this process, the materials on the fluidized bed are fluidized and conveyed simultaneously.
4. Blowing phase
When the materials inside the pump are conveyed completely, and the pressure drops to pipeline resistance, The indicator light gives out a signal. The air continues to be taken in for a given time. Compress the air, and clean the pipeline. And then close the air inlet valve at a regular interval, close the discharge valve, open the feeding valve and complete one conveying cycle.
The above processes are performed automatically.
