Overview
GSB solid jet pump is a combination of principle of pneumatic pressure difference with the most advanced jet flow and fluidization technology,  it is fully absorbs the theory of modern pneumatic conveying two-phase flow. The feeding part is an electric air lock. the powder material is sucked into the air ash mixing chamber after the electric air lock completes the balanced feeding function , and the material and gas are evenly mixed by the jet nozzle (defined by the company as the de Laval 's principle) , and the material is sent to the conveying pipeline and arrived at the destination along the pipeline by the pneumatic pressure difference. The overall transmission efficiency is 3 to 4 times higher than that of traditional injectors.
The core technology is the jet nozzle and the shape is ring,  adding a tongue in the middle of the nozzle to form a ring with a solid center when manufacturing it . It is also subsonic, sonic, and supersonic, but the gradual expansion of the supersonic area is focused inward rather than outward, and produces focus in the hybrid section of the venturi tube. the most important point that the equipment is different from other conveying pumps is that  jet can produce a higher vacuum without causing turbulence and energy loss, 

Main component 
The GSB solid jet pump is composed of three parts:  intermediate bin,  electric air lock and  feed emitter (gas-ash mixing chamber, nozzle and venturi tube).

Application industry
all kinds of bulk and powder material transportation on Power, building materials, large concrete mixing station, metallurgy, steel, chemical, grain and other industries
Main innovations:
● Continuous transmission, the valve does not need to open and close frequently, and the failure rate is very small.
● Multi-pump multi-stage series transmission compared with a large number of hopper single-stage transmission pump mode, reduce the investment cost of at least 5%, simple operation, easy operation, reduce the point of failure.
● Multi-pump multi-stage series transmission mode, can reduce the frequent transmission times, reduce energy consumption, and transport at the same time, always ensure that the ash down the hopper can be emptied at the same time and in time, not easy to cause ash accumulation in the hopper.
● Low pressure Roots fan is used for power gas source, which has low energy consumption and low operating cost, saving 20% compared with dense phase ash transport system.
● The use of low-pressure power source for continuous transmission, the flow rate in the pipeline is low and constant, the pipeline wear is small, long service life.
● Continuous transmission, the system runs smoothly, basically no blocked pipe phenomenon, safe and reliable, can be unattended.
● Continuous transmission, the tube flow rate is low and constant, so less wear, the power fan without any impact load, so the system and all equipment long life.
● Small size, simple installation, easy maintenance.
● No leakage, in line with environmental requirements.
