Product
bunker pump
It is a key equipment in the pneumatic conveying system used to intermittently transport powder or granular materials from one location to another. It achieves efficient material transmission through three stages of periodic filling, pressurization and discharge, and is especially suitable for long-distance, high-lift material transportation tasks. The design of the silo pump allows it to handle various types of dry bulk materials and adapt to different conveying conditions.
Principle
Charging stage: The bin pump is in a low-pressure state, the feed valve is opened, and materials enter the bin pump through gravity or auxiliary equipment (such as screw feeder). When the material reaches the preset amount, close the feed valve and prepare to enter the next stage.
Pressurization stage: The air inlet valve opens, and compressed air or other gases are injected into the warehouse pump, causing the pressure in the warehouse pump to gradually increase to the set value. As the pressure increases, the material is compacted and forms columns with a certain density.
Discharging stage: The discharge valve is opened, and the high-pressure gas pushes the materials to move along the conveying pipeline until they are all discharged. After the discharge is completed, the discharge valve is closed and the warehouse pump returns to the initial low-pressure state to prepare for the next filling.
Purge stage (optional): In order to ensure that the pipeline is unobstructed, sometimes a short purge is performed after discharging to remove the material remaining in the pipeline.
