PJP type positive pressure dilute phase pneumatic conveying jet pump

 PJP type positive pressure dilute phase pneumatic conveying jet pump 

       PJP type positive pressure dilute phase pneumatic conveying jet pump is a kind of low pressure, dilute phase, continuous pneumatic conveying equipment. It is installed at the bottom of the silo (reservoir) and uses the pressure of the material in the silo (library) or the air-locking unloading device. Compressed air transports the particulate material through the delivery line to the desired material reservoir.

Working principle

PJP type jet pump pneumatic conveying system is composed of PJP type jet pump, pneumatic butterfly valve, pump top bin, manual screw gate and compressed air supply device. The compressed air source is mainly Roots blower. The powdery granular material enters the PJP type jet pump through a manual screw gate, a pump top chamber, and a pneumatic butterfly valve. When the compressed air for conveying passes through the nozzle of the PJP type jet pump casing, the high-speed airflow generated causes a negative pressure state in the PJP-type jet pump casing, and the material in the pump top bin is easily mixed with the high-speed airflow, and then the material is mixed. The gas mixture converts the kinetic energy of the high-speed gas stream into static pressure energy when passing through the expansion tube of the PJP type injection device, thereby conveying the powdery granular material to the terminal through the delivery pipe. The manual screw gate of PJP type jet pump is used for commissioning and overhaul. The pneumatic butterfly valve is used for the suspension of powdery granular material transportation and automatic shutdown when 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 (reservoir), the material is transported by the pressure of the material in the silo (warehouse). When the height of the material in the silo (warehouse) changes, the material transport will be caused. The speed changes accordingly, so the material handling capacity depends on the material height in the silo (warehouse).

When the PJP type positive pressure dilute phase pneumatic conveying jet pump is equipped with a lock air device, the material conveying capacity depends on the air lock capacity of the air lock device.

Main features of the product

PJP type positive pressure dilute phase pneumatic conveying jet pump is a pneumatic conveying device with automatic control, compact performance, reliable performance, simple maintenance, long service life and low investment cost. The moving part is just material and air. When connected to a dust removal unit, its fully enclosed system design provides a completely dust-free working environment.

Application field

PJP type positive pressure dilute phase pneumatic conveying jet pump is a kind of low pressure, dilute phase, continuous pneumatic conveying equipment, suitable for occasions where the conveying volume is not very large and the conveying distance is medium. Can be widely used in building materials, chemicals, electricity, food, metallurgy, foundry and other industries. The conveying materials are: cement, raw meal, fly ash, slaked lime, slag powder, steel slag powder, coal powder, alumina powder, phosphor powder, pyrophyllite powder and silicone powder.
