倉 泵

　　Warehouse pump

　　倉泵又稱倉式泵，是在高壓下（約700kPa以下）輸送粉狀物料的一種比較可靠的密相動壓氣力輸送裝置。

　　Warehouse pump, also known as bin pump, is a reliable dense phase dynamic pressure pneumatic conveying device that transports powdered materials under high pressure (about 700kPa or below).

　　倉式泵的卸料方式有兩種，下引式和上引式；其中下引式是底部出料的常用方式，罐內(nèi)物料通過圓錐面充氣槽充氣、噴嘴噴氣或其它方法得以流態(tài)化；在底部設(shè)置流態(tài)化充氣板（層）可使物料在罐的下部卸出。上引式是從罐體的上部卸料，輸送氣體在罐中不同輸入平面上分布情況取決于輸送物料性質(zhì)。

　　There are two unloading methods for warehouse pumps, downward and upward; The downward drawing method is a common way of bottom discharge, where the material inside the tank is fluidized by inflating it through a conical surface inflation groove, spraying it with a nozzle, or other methods; Setting up a fluidized inflatable plate (layer) at the bottom allows the material to be discharged from the lower part of the tank. Upward loading refers to unloading from the upper part of the tank, and the distribution of the conveyed gas on different input planes in the tank depends on the properties of the conveyed material.

　　倉式泵輸送是一個不斷間歇性輸送過程。在倉式泵進(jìn)料以前，料倉內(nèi)裝有被輸送物料，閥門都是關(guān)閉的。

　　Warehouse pump conveying is a continuous intermittent conveying process. Before the silo pump feeds, the silo is filled with the conveyed material and all valves are closed.

　　操作工作過程如下；

　　The operation process is as follows:;

　　1、首先打開進(jìn)料閥和排氣閥，物料通過料倉在常壓下進(jìn)料，達(dá)到水平料位計設(shè)定倉滿指示信號為止；

　　1. Firstly, open the feed valve and exhaust valve, and the material is fed through the silo at normal pressure until it reaches the full level indicator signal set by the horizontal level gauge;

　　2、然后關(guān)閉進(jìn)料閥和排氣閥，打開高壓氣閥使罐內(nèi)加壓；

　　2. Then close the feed valve and exhaust valve, and open the high-pressure valve to pressurize the tank;

　　3、當(dāng)達(dá)到操作壓力后，打開輸送空氣閥門和卸料閥，物料開始輸送；

　　3. When the operating pressure is reached, open the conveying air valve and discharge valve, and the material begins to be conveyed;

　　4、由壓力開關(guān)、料位計或時間繼電器顯示出輸送結(jié)束。此時關(guān)閉高壓氣閥和卸料閥，使全部壓縮空氣都用來清吹輸送管道；同時打開排氣閥，使罐內(nèi)壓力減至常壓狀態(tài)。一個工作周期完成后，啟動另一周期繼續(xù)進(jìn)行。

　　4. The end of conveying is indicated by pressure switches, level gauges, or time relays. At this time, close the high-pressure air valve and discharge valve, so that all compressed air is used to blow the conveying pipeline; Simultaneously open the exhaust valve to reduce the pressure inside the tank to atmospheric pressure. After one work cycle is completed, start another cycle to continue.
