PJP Type Positive Pressure Dilute Phase Pneumatic Conveying Jet Pump

Long-Distance Powder Ejector Pump - Low Pressure Pneumatic Conveying System for Ash & Powders

Description

Positive pressure dilute phase pneumatic conveying jet pump is a device that uses the positive pressure generated by compressed air to transport granular materials in a dilute phase state. It is suitable for situations where the conveying volume is not very large and the conveying distance is medium.

PJP Type Positive Pressure Dilute Phase Pneumatic Conveying Jet Pump

Powder Conveying Equipment operational principle
The PJP jet pump pneumatic conveying system consists of a PJP jet pump, a pneumatic butterfly valve, a pump top compartment, a manual spiral gate, and a compressed air supply device. The main source of compressed air is the Roots blower. Powder and granular materials enter the PJP jet pump through manual spiral gates, pump top bins, and pneumatic butterfly valves. When compressed air for transportation passes through the nozzle inside the PJP type jet pump box, the high-speed airflow generated creates a negative pressure state inside the PJP type jet pump box. The materials in the top compartment of the pump are easily mixed with the high-speed airflow.

Then, when the material gas mixture passes through the expansion pipe of the PJP type jet device, the kinetic energy of the high-speed airflow is converted into static pressure energy, thereby conveying powder and granular materials to the terminal through the conveying pipeline. The manual spiral gate of the PJP jet pump is used for debugging and maintenance, and the pneumatic butterfly valve is used for automatically closing when the transportation of powder and granular materials is suspended or the system pressure is abnormal.
When the PJP type positive pressure dilute phase pneumatic conveying jet pump is installed at the bottom of the silo  to transport materials using the pressure of the materials in the silo , changes in the height of the materials in the silo will cause corresponding changes in the material conveying speed. Therefore, the conveying energy of the materials depends on the height of the materials in the silo .
When the PJP type positive pressure dilute phase pneumatic conveying jet pump is equipped with a locking device, the conveying capacity of the material depends on the locking capacity of the locking device.

Main features of the product
PJP type positive pressure dilute phase pneumatic conveying jet pump is a pneumatic conveying device with automatic control, which has a compact structure, reliable performance, simple maintenance, long service life, and low investment cost. The moving parts are only materials and air. When connected to the dust removal device, its fully enclosed system design can provide a completely dust-free working environment.
