Jet conveying pump-low pressure continuous conveying pump

Overview of jet delivery pumps, low-pressure continuous delivery pumps
The PSB series continuous pneumatic conveying pump is an ideal low-pressure continuous conveying powdery material developed and designed by Gongyi Ruiguang Machinery Factory, and has obtained national patent. This product is widely suitable for medium and short-distance ash collection and transportation in industries such as electric ash removal, building material transfer, large construction sites, etc. It is not restricted by terrain, ground features, height differences, fully enclosed, pollution-free, simple structure, and small maintenance . The air source can be selected from centrifugal fans, roots fans, compressed air and other air sources according to the distance.

Various series of energy-saving low-pressure continuous conveying pumps (abbreviated as low-pressure continuous conveying pumps) produced by Henan Ruiguang Machinery Factory are newer generations of technical optimization and improvement by technical staff of our company through more than 20 years of production and operation experience. Sixth generation) Energy-saving low-pressure continuous pneumatic conveying equipment.
The continuous pump has been widely used in the transportation of powdery materials in water conservancy and hydropower construction sites and urban commercial concrete mixing buildings (stations) systems, the collection of ash under the ash bucket of the electric dust collector in thermal power plants, the transportation of petroleum coke, metallurgy, chemical industry, Building materials, wharf and other industries in the transportation of powdery materials.
The continuous pump has the characteristics of simple structure, reliable operation, low system cost and operation cost, and high degree of automation. For more than 20 years, it has been used in ash removal in thermal power plants, ash collection in boiler dust collectors, water conservancy and hydropower projects, terminal transfer station projects, urban commercial concrete mixing stations, and metallurgical powder transportation in chemical plants. Thousand sets.

Principle of ash conveying jet conveying pump <br /> The material enters into the jet conveying pump chamber uniformly and constantly from the air lock. After fluidizing once in the fluidization box, it has a tendency to flow to the nozzle. A negative pressure zone is formed between the inner tubes, and the fluidized material is rolled into the mixing tube, and then decelerated and pressurized by the diffusion pipe section, so that the material is transported to the destination.
The energy-saving and low-pressure continuous conveying pump uses Roots fan as the power source, uses the principle of gas-solid two-phase flow, combines fluidization technology, jet technology and pressure difference principle, and uses electric impeller air lock as the feeding device to feed materials. It is sent into the material-gas mixing chamber. While the material is fluidized in the material-gas mixing chamber, the material is sent into the acceleration chamber by the high-speed airflow generated by the double-ring nozzle, and enters the transportation pipeline in a suspended flow. Feed into the receiving bin. After filtering through a bag filter, the gas is separated and the gas is discharged into the atmosphere.

The advantages of jet conveying pump , low pressure continuous conveying pump and continuous jet conveying pump are simple structure and reliable operation: continuous conveying pump is composed of electric impeller air lock and feeder. The electric impeller air lock completes the balanced feeding and air lock. It presses the material from normal pressure into a low positive pressure system; the feeder uses a uniquely designed nozzle to uniformly mix the material and the conveying gas, and sends the material to the conveying. In the pipe, the pneumatic pressure difference is used to make the material along the pipeline to the receiving destination. The overall structure is simple, and only the electric impeller air lock is a rotating part, so the operation is extremely reliable.
The jet conveying pump has the advantages of low investment, low operating cost, and obvious energy saving. The low-pressure continuous conveying system composed of continuous pumps not only reflects its investment savings in project cost, but also has low operating costs. Because there are no inlet, outlet and exhaust valves, and no wearing parts, the operating cost is low. Due to the use of low-pressure roots blower air source transportation, it saves about 40% of energy consumption compared to traditional warehouse pump high-pressure air compressor system transportation.
Convenient operation, small wear of equipment and pipelines, and long service life. The main body control of the equipment only has electric impeller air lock. The main body control of the equipment only needs to be "started" or "stopped". The operation of the equipment only needs to be inspected, and no manual inspection is required. Because the process system of the continuous delivery pump is simple, the control system configured is correspondingly simple. Due to the low-pressure conveying, the flow velocity in the equipment and the ash conveying pipe is low, and the conveying concentration is constant. As a result, system equipment and piping are less abrasive and have a longer service life.
The system layout is convenient and flexible, and the quality of the gas source is not high. Due to the small size of the equipment and the low installation height, it is convenient and flexible in system layout, which can fully meet the needs of engineering layout. Roots blowers are generally used for the power source of continuous delivery pumps, and no air purification system is required. According to the system design, there are only certain requirements for air volume and pressure. According to the customer's situation, the existing air compressor can be used to compress the gas source.
The system has high reliability, economical and reasonable, low cost, and low system operating cost. The low-pressure pneumatic continuous conveying system composed of low-pressure continuous conveying pumps has reliability that cannot be achieved by any other pneumatic conveying equipment. This is due to the fact that the power source of the low-pressure continuous transmission system generally uses roots fans (also may use high-pressure centrifugal fans or air compressors as appropriate). The high reliability of roots fans determines the reliability of the system.  
The pneumatic conveying system is composed of a continuous conveying pump. Generally, the number and types of equipment are small, making the whole system simple and reliable. Continuous conveying pressure is stable without any impact load. The equipment itself is simple, there is no frequent action of the valve in the pneumatic conveying process of the conventional warehouse pump, and the equipment failure rate is greatly reduced. The low-pressure continuous pneumatic conveying system composed of low-pressure continuous conveying pumps, due to the above characteristics, also has the characteristics of low cost and excellent operating indicators. Therefore, the superiority of this system: not only reflects its investment savings when the project is launched, but also that it will continue to reflect lower operation and maintenance costs in the future operation and use process.

Operating conditions of continuous jet delivery pump <br /> Continuous jet delivery pump operating mode: continuous, discontinuous. The air source pressure has wide adaptability, and the working pressure is 50-100Kpa, depending on the conveying distance and conveying capacity. Conveying distance <250m, height <32m, temperature -20 ℃ ~ 150 ℃, conveying air volume and conveying pipe size also vary with different conveying capacity and conveying distance. Generally, it can be selected according to QLB continuous conveying pump series matching table.
