一.倉泵主要構成

　　One The main components of the warehouse pump

　　1、進料裝置也叫進料閥，設置在氣力輸送倉泵上部，進料閥直接與倉泵相連接并結合為一個整體。

　　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、排氣裝置也叫排氣閥，設置在氣力輸送倉泵上部，其作用為通過氣缸的動作，打開或關閉閥門，使氣力輸送倉泵內余氣排出至貯料倉。

　　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、進氣/流態(tài)化裝置也叫氣化室，它設置在氣力輸送倉泵的底部，中部設置噴射管。

　　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、氣動出料閥設置于氣力輸送倉泵物料出口處，氣力輸送倉泵輸送時，該閥打開，氣力輸送倉泵輸送結束時，該閥關閉。工作時，氣缸通過活塞桿帶動雙閘板閥芯做上下運動，從而來打開或關閉閥門。

　　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、泵體作為整個輸送系統(tǒng)的發(fā)送時物料存貯裝置，它是一個耐磨損、抗疲勞的壓力容器，能長期經受氣流和物料的沖刷和磨損。

　　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、電氣控制柜通常是一臺氣力輸送倉泵一個控制柜。

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

　　7、氣動控制箱即電磁閥箱，箱內一般配置了控制每臺氣力輸送倉泵氣缸工作的電磁閥，通常是一臺氣力輸送倉泵配置一個電磁閥箱。

　　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．倉泵工作原理

　　2、 Working principle of warehouse pump

　　倉泵本體是能承受一定壓力與溫度的壓力容器，其上端為為氣動進料閥，內部為一上引式管道，與氣動出料閥及輸灰管道相連。氣動進料閥，氣動出料閥，進氣閥，二次氣閥均有電磁氣動換向閥控制。倉泵采用間歇式自動控制方式運行。每個輸送過程可分為四個階段，有感應信號及程序控制。

　　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.進料階段。進料閥開啟。進氣閥和出料閥在關閉狀態(tài)。倉泵內部與電除塵灰斗聯(lián)通，飛灰進入倉泵，當倉泵內灰位高至于料位計探頭接觸，則料位計產生一料位滿信號，并通過現(xiàn)場控制單元進入程序控制器，系統(tǒng)自動關閉進料閥。

　　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.加壓流化階段。進氣閥開啟。進料閥，出料閥及二次吹掃閥關閉，壓縮空氣通過流化盤進入倉泵，飛灰流化，當倉泵內壓力升高到某一設定數(shù)值時，出料閥打開，結束加壓流化。

　　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.輸送階段。進氣閥及出料閥開啟。進料閥及二次吹掃閥關閉，灰氣混合物進入輸送管道，此時倉泵內壓力保持平穩(wěn)(0.15~0.25MPA)。當倉泵內飛灰輸送結束時，管路阻力降低，倉泵內壓力下降，當降至下限壓力數(shù)值時，結束輸送狀態(tài)。

　　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.吹掃階段。二次吹掃閥開啟，進料閥關閉。進氣閥，出料閥仍保持開啟狀態(tài)，壓縮空氣清掃倉泵及管道內的余灰，此時倉泵內無飛灰，管道內飛灰逐步減少，非常后幾乎呈空氣流動狀態(tài)。系統(tǒng)阻力下降，倉泵壓力降至一穩(wěn)定值，定時一段時間后吹掃結束。進氣閥，出料閥及二次氣閥關閉，進料閥開啟，倉泵恢復到進料狀態(tài)。

　　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.
