Low pressure continuous delivery pump

Product Overview

The JT. G series low-pressure continuous conveying pump is a rotary feeding impeller structure, with sealing ensured by precision grinding. It is often powered by a Roots blower for conveying, with low flow rate and concentration, and minimal impact and wear on pipelines. It belongs to a low-pressure dilute phase pneumatic conveying system. The system has a simple structure, reliable operation, small installation space, and no frequent valve movements. It has the characteristics of low cost and low operation and maintenance costs, making it an ideal equipment for short distance continuous transportation.

Structural characteristics

JT. G series low-pressure continuous conveying pump is a pneumatic conveying system that combines high-speed jet, powder fluidization, and pneumatic pressure difference. The core components of the shell and impeller are both surface chrome plated after precision grinding. The impeller is designed with eight to ten T-shaped anti cross flow blades, effectively reducing the impact of reverse cross flow on feeding during transportation. The wing shaped annular nozzle produces turbulent flow while increasing the jet velocity, which has a good fluidization effect on the falling powder. The entire system is easy to operate, with uniform feeding, good fluidization, low backflow volume, and extremely smooth conveying. The comprehensive advantages of the system's process are obvious, and its technical content is superior to that of the domestic industry.

Transport principle

JT. G series low-pressure continuous conveying pump is a new type of conveying equipment designed by combining the principle of pneumatic pressure difference with modern gas-solid two-phase flow theory, with Roots blower as the power source. The powder falls into the wheel grid of the electric air lock through the discharge port under the action of gravity. The air lock enters the mixing chamber in a timed and quantitative manner through uniform rotation. The high-speed airflow and turbulent flow generated by the wing shaped ring nozzle push the mixed powder into the acceleration chamber and transport it along the pipeline to the terminal silo under the action of pneumatic pressure difference. The mixture of ash and gas is separated by gravity, and the powder falls into the bottom of the silo. The air is discharged into the atmosphere through the dust removal equipment.

Scope of application

The JT. G series low-pressure continuous conveying pump adopts impeller type rotating feeding and uses low-pressure Roots blower as the power source. Therefore, the system is only suitable for continuous transportation at close distances. Transport equivalent distance ≤ 300m, vertical height ≤ 30m, bulk density ≤ 2.0t/m3, powder fineness ≤ 20 mesh, moisture content ≤ 3% (based on no clumping during free fall after grasping), instantaneous temperature of powder ≤ 280 ℃.
