I. Overview of material seal pump
Fucheng low-pressure pneumatic conveying equipment material-sealed pump series of products, based on the introduction of foreign advanced technology, a new type of low-pressure pneumatic conveying pump equipment developed for the various problems of different types of pneumatic conveying equipment in the domestic industry.
The material seal pump is widely used in thermal power plant, thermal power plant pneumatic ash removal system, water conservancy and hydropower construction site and urban commercial concrete mixing building, mixing station system for powdery material transportation, cement homogenization and inverted storage, various powdery materials. Conveying, and powdery materials conveying and transferring process in metallurgy, chemical industry, building materials, docks and other industries. Fucheng series low-pressure pneumatic conveying equipment material seal pump has been successfully used in many powder engineering projects, and is one of the most ideal pneumatic conveying equipment for powdery materials.

Working principle and structural characteristics of material seal pump
The low-pressure pneumatic conveying equipment material seal pump is a combination of the principle of pneumatic pressure with jet flow technology and fluidization technology, fully absorbing the modern pneumatic conveying theory. After years of operation and practice summary, a large number of requirements for the powder pneumatic conveying process system Special equipment developed for continuous conveyance. Compared with other pneumatic conveying equipment, such as a silo pump, this equipment has the following characteristics:
1. Simple structure and reliable operation. The material sealing pump of the low-pressure pneumatic conveying equipment enters the material from the normal pressure into the material sealing pump. The uniquely designed ejection device is used to send the material into the conveying pipe. The pneumatic pressure difference is used to make the material move along the pipeline. To the receiving destination. The overall structure is simple and the operation is extremely reliable.
2. Low wear and long service life. Due to continuous conveyance, low pressure and large air volume, the flow velocity in the pipe is low and constant, so the wear is small and the service life of the entire system is long.
3. The arrangement is convenient and flexible. The material-sealed pump can be arranged as a single pump, a single pipe or a multi-pump common pipe, and a multi-pump common gas source according to the specific conditions of the system. The pipelines can be arranged horizontally, vertically, and obliquely up to meet the ever-changing layout requirements of the project.
4. Fully sealed and pollution-free conveying, which meets its own environmental protection and the quality requirements of the project. Since the material-sealed pump adopts low positive pressure and full-sealed conveying, external substances cannot enter the pipe, so it will not cause the required material properties. Any changes.
5. Stable transportation, because continuous transportation is used to utilize low pressure and large air volume, there is no pipe blocking phenomenon.
6. Simple operation. Since the equipment has only a limited number of operating parts and only supporting roots fans, the main body control only needs to be “started up” and “stopped”. It does not require manual inspection and inspection. Due to the simple process system of the continuous delivery pump, the logical relationship of the control system configured is simple, and the operation is simple and reliable.
7. The quality of the gas source is not high. Because it adopts the form of continuous conveyance and the power source of the power is generally a roots blower, the power source does not generally need to set up a purification system. It only has certain requirements for the volume and pressure of the gas. You can use an independent gas source or an air source (centralized gas source) commonly used in engineering.
8. High system reliability. The low-pressure pneumatic continuous conveying system composed of the material sealing pump of the low-pressure pneumatic conveying equipment has reliability that cannot be achieved by any other pneumatic conveying equipment. This is because: Low-pressure continuous conveying systems generally use 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 device itself is simple, and there is no frequent action of the valve in the conventional pneumatic conveying process, and the failure rate of the device is greatly reduced. The pneumatic conveying system is composed of the low-pressure pneumatic conveying equipment material sealing pump. Generally, the number and types of equipment are small, which makes the whole system simple and reliable. Continuous conveying pressure is stable without any impact load.
9. Economical and reasonable, low cost, low system operation cost, low pressure continuous pneumatic conveying system composed of low pressure pneumatic conveying equipment material sealing pump, 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!

Three. Material sealing pump selection principle and applicable conditions
1.Selection principle <BR> Select low-pressure pneumatic conveying equipment material seal pump as the core equipment to form a pneumatic conveying system. First of all, the user should provide: the required volume of the system, the conveying distance, or the physical and chemical parameters of the material, the maximum temperature and normal working temperature If it is under the boiler dust collector, basic parameters such as the dust bucket layout and ash distribution of the dust collector should be provided. Then the technical personnel of our factory first determine the basic transportation plan, such as the required air volume, how to group, the continuous pump model, the configuration of the intake and transmission pipelines, and the configuration of the deduster at the top of the warehouse.
2. Applicable conditions <BR> The material sealing pump of the low-pressure pneumatic conveying equipment uses low-pressure conveyance, so the range of use is limited. It can only be used normally and safely under the following conditions and achieve the expected effect.
Conveying distance ≯500m (equivalent distance).
Material bulk density: 2.0t / m3 (powder).
The maximum cascade pump is not more than 4 (that is, 4 ash conveying pipes in total).
The maximum instantaneous temperature of the material is ≯250 ℃.
(For the concrete mixing building and mixing station powder conveying system, if the air compressor is used as the power source, the conveying distance is ≥300m. The specific parameter configuration needs to be changed accordingly. It will be calculated and determined separately according to the site conditions and system process requirements.)
