A necessary condition for the proper operation of the material conveying pump is maintaining a specific material seal height. The pressure exerted by the material level in the silo must exceed the positive operating pressure within the pump; this pressure differential isolates the positive and negative pressure zones, allowing the blower's airflow to transport the material. Therefore, a sufficient material level height is essential.
A dust collector must be installed on the receiving silo, and its exhaust capacity must exceed the blower's intake airflow. If the intake airflow exceeds the exhaust capacity, the pressure inside the receiving silo rises, causing system imbalance and increased pipeline resistance. This forces air to backflow from the conveying pump into the upper section of the silo, preventing the pump from operating correctly.
