NMT precision feeding injection pump is based on the dense phase transfer pump configuration volume metering feeding device, can achieve stable, adjustable, high dynamic precision metering of material injection, compared with the traditional fluidized pressure differential injection tank, injection is more stable, more accurate, easier to operate, more reliable, the technology is widely used in various production processes of raw materials, fuels or additives of high-precision metering feeding system, such as blast furnace coal injection system, electric furnace toner injection system, molten iron pretreatment desulfurizer injection system, Circulating fluidized bed boiler limestone injection system, lime kiln pulverized coal injection system, Ausmelt furnace and Isasmelt furnace pulverized coal injection system, bottom blowing furnace, side blowing furnace and smoke furnace pulverized coal injection system, copper smelting converter copper concentrate injection system, gasifier pulverized coal injection system, etc.
Unique rotary feeding design.
It can be used for both single-point and multi-point injection.
The conveying medium is wide, whether it is powder material or granular material, or highly abrasive and corrosive substance, etc
The injection accuracy is high, up to ±0.5%.
The conveying distance can reach thousands of kilometers.
The conveying capacity can reach up to 300m3/h.
The feeding amount can be controlled by adjusting the speed of the inverter motor, and the maximum speed ratio of the motor can reach 10:1.
The material can be injected directly into a pressurized environment and can withstand back pressures in excess of 30 barg.
The system adopts a dome valve, and the dome valve spool does not contact with any metal surface when opening and closing, which greatly reduces the valve wear on the system Performance impact. The valve can operate continuously for 1 million cycles, so the maintenance cost is low. The dome valve is tightly sealed and not easy to leak, ensuring the reliability of the system.
The whole system adopts a fully enclosed and environmentally friendly design, and there is no dust leakage.
It can be arranged in parallel or tandem according to the space conditions.
