一.仓泵主要构成

　　One The main components of the warehouse pump

　　1、进料装置也叫进料阀，设置在气力输送仓泵上部，进料阀直接与仓泵相连接并融合为一个整体。

　　1. The feeding device, also known as the feeding valve, is located above the pneumatic conveying bin pump. The feeding valve is directly connected to the bin pump and integrated into a whole.

　　2、排气装置也叫排气阀，设置在气力输送仓泵上部，其作用为通过气缸的动作，打开或关闭阀门，使气力输送仓泵内余气排出至贮料仓。

　　2. The exhaust device, also known as the exhaust valve, is installed on the upper part of the pneumatic conveying bin pump. Its function is to open or close the valve through the action of the cylinder, so that the residual air in the pneumatic conveying bin pump is discharged to the storage bin.

　　3、进气/流态化装置也叫气化室，它设置在气力输送仓泵的底部，中部设置喷射管。

　　3. The intake/fluidization device, also known as the gasification chamber, is located at the bottom of the pneumatic conveying bin pump, with a spray pipe in the middle.

　　4、气动出料阀设置于气力输送仓泵物料出口处，气力输送仓泵输送时，该阀打开，气力输送仓泵输送结束时，该阀关闭。工作时，气缸通过活塞杆带动双闸板阀芯做上下运动，从而来打开或关闭阀门。

　　4. The pneumatic discharge valve is set at the material outlet of the pneumatic conveying bin pump. When the pneumatic conveying bin pump is conveying, the valve opens, and when the pneumatic conveying bin pump is conveying, the valve closes. During operation, the cylinder drives the double gate valve core to move up and down through the piston rod, thereby opening or closing the valve.

　　5、泵体作为整个输送系统的发送时物料存贮装置，它是一个耐磨损、抗疲劳的压力容器，能长期经受气流和物料的冲刷和磨损。

　　5. As the material storage device for the entire conveying system, the pump body is a wear-resistant and fatigue resistant pressure vessel that can withstand the erosion and wear of airflow and materials for a long time.

　　6、电气控制柜通常是一台气力输送仓泵一个控制柜。

　　6. The electrical control cabinet usually consists of one pneumatic conveying bin pump and one control cabinet.

　　7、气动控制箱即电磁阀箱，箱内一般配置了控制每台气力输送仓泵气缸工作的电磁阀，通常是一台气力输送仓泵配置一个电磁阀箱。

　　7. Pneumatic control box, also known as solenoid valve box, is generally equipped with solenoid valves that control the operation of each pneumatic conveying bin pump cylinder. Typically, one pneumatic conveying bin pump is equipped with one solenoid valve box.

　　二．仓泵工作原理

　　2、 Working principle of warehouse pump

　　仓泵本体是能承受一定压力与温度的压力容器，其上端为为气动进料阀，内部为一上引式管道，与气动出料阀及输灰管道相连。气动进料阀，气动出料阀，进气阀，二次气阀均有电磁气动换向阀控制。仓泵采用间歇式自动控制方式运行。每个输送过程可分为四个阶段，有感应信号及程序控制。

　　The main body of the warehouse pump is a pressure vessel that can withstand a certain pressure and temperature. Its upper end is a pneumatic feed valve, and the interior is an upward pipeline connected to the pneumatic discharge valve and ash conveying pipeline. Pneumatic feed valve, pneumatic discharge valve, intake valve, and secondary air valve are all controlled by electromagnetic pneumatic directional valves. The warehouse pump operates in an intermittent automatic control mode. Each conveying process can be divided into four stages, with induction signals and program control.

　　1.进料阶段。进料阀开启。进气阀和出料阀在关闭状态。仓泵内部与电除尘灰斗联通，飞灰进入仓泵，当仓泵内灰位高至于料位计探头接触，则料位计产生一料位满信号，并通过现场控制单元进入程序控制器，系统自动关闭进料阀。

　　1. Feed stage. The feed valve is open. The intake valve and discharge valve are in the closed state. The interior of the bin pump is connected to the electrostatic precipitator ash hopper, and fly ash enters the bin pump. When the ash level in the bin pump is high enough to contact the level gauge probe, the level gauge generates a level full signal, which enters the program controller through the on-site control unit, and the system automatically closes the feed valve.

　　2.加压流化阶段。进气阀开启。进料阀，出料阀及二次吹扫阀关闭，压缩空气通过流化盘进入仓泵，飞灰流化，当仓泵内压力升高到某一设定数值时，出料阀打开，结束加压流化。

　　2. Pressure fluidization stage. The intake valve is open. The feed valve, discharge valve, and secondary purge valve are closed, and compressed air enters the bin pump through the fluidized disc to fluidized fly ash. When the pressure inside the bin pump rises to a certain set value, the discharge valve opens to end pressurized fluidization.

　　3.输送阶段。进气阀及出料阀开启。进料阀及二次吹扫阀关闭，灰气混合物进入输送管道，此时仓泵内压力保持平稳(0.15~0.25MPA)。当仓泵内飞灰输送结束时，管路阻力降低，仓泵内压力下降，当降至下限压力数值时，结束输送状态。

　　3. Transport phase. The intake valve and discharge valve are open. The feed valve and secondary purge valve are closed, and the ash gas mixture enters the conveying pipeline. At this time, the pressure inside the bin pump remains stable (0.15~0.25MPA). When the fly ash transportation in the silo pump is completed, the pipeline resistance decreases and the pressure inside the silo pump decreases. When it reaches the lower limit pressure value, the transportation state is ended.

　　4.吹扫阶段。二次吹扫阀开启，进料阀关闭。进气阀，出料阀仍保持开启状态，压缩空气清扫仓泵及管道内的余灰，此时仓泵内无飞灰，管道内飞灰逐步减少，最后几乎呈空气流动状态。系统阻力下降，仓泵压力降至一稳定值，定时一段时间后吹扫结束。进气阀，出料阀及二次气阀关闭，进料阀开启，仓泵恢复到进料状态。

　　4. Purging stage. The secondary purge valve is open and the feed valve is closed. The intake valve and discharge valve remain open, and compressed air is used to clean the residual ash in the bin pump and pipeline. At this time, there is no fly ash in the bin pump, and the fly ash in the pipeline gradually decreases, finally almost in an air flow state. The system resistance decreases, and the pressure of the bin pump drops to a stable value. After a certain period of time, the blowing ends. The intake valve, discharge valve, and secondary air valve are closed, the feed valve is opened, and the bin pump returns to the feeding state.
