倉(cāng)泵是氣力輸送系統(tǒng)中不可或缺的組成部分，它具有輸送距離遠(yuǎn)、輸送能力大、管道布置靈活、減少設(shè)備投資等特點(diǎn)。由于其應(yīng)用場(chǎng)景多集中在工業(yè)領(lǐng)域，很多行業(yè)外的人對(duì)它并不熟悉，甚至聞所未聞，對(duì)其工作原理更是知之甚少。下面就來(lái)詳細(xì)了解一下倉(cāng)泵的相關(guān)知識(shí)。

　　Warehouse pump is an indispensable component of pneumatic conveying system, which has the characteristics of long conveying distance, large conveying capacity, flexible pipeline layout, and reduced equipment investment. Due to its application scenarios mostly concentrated in the industrial field, many people outside the industry are not familiar with it, or even unheard of, and know very little about its working principle. Let's take a detailed look at the relevant knowledge of warehouse pumps below. 

　　倉(cāng)泵的卸料方式主要有兩種，其中底部出料是最為常見的一種。在這種方式中，罐內(nèi)的物料通過(guò)圓錐面充氣槽的充氣、噴嘴噴氣或其他專門設(shè)計(jì)的方法實(shí)現(xiàn)流態(tài)化，使物料能夠順利從底部排出。另一種卸料方式是上部出料，通過(guò)在罐底部設(shè)置流態(tài)化充氣板，讓物料在氣體的作用下向上流動(dòng)，從而從罐的上部卸出。不同的卸料方式適用于不同的物料特性和輸送需求，比如對(duì)于流動(dòng)性較差的物料，可能需要更強(qiáng)勁的充氣裝置來(lái)輔助卸料，而輸送氣體在罐內(nèi)不同輸入水平上的分布情況，會(huì)根據(jù)輸送物料的顆粒大小、比重、濕度等性質(zhì)進(jìn)行針對(duì)性設(shè)計(jì)，以確保卸料過(guò)程穩(wěn)定高效。

　　There are two main unloading methods for warehouse pumps, among which bottom discharge is the most common. In this method, the material inside the tank is fluidized through the inflation of the conical surface inflation groove, nozzle spraying, or other specially designed methods, allowing the material to be smoothly discharged from the bottom. Another unloading method is upper discharge, which involves setting up a fluidized inflatable plate at the bottom of the tank to allow the material to flow upward under the action of gas and be discharged from the upper part of the tank. Different unloading methods are suitable for different material characteristics and conveying needs. For example, for materials with poor fluidity, stronger inflation devices may be required to assist in unloading. The distribution of conveying gas at different input levels in the tank will be designed according to the particle size, specific gravity, humidity, and other properties of the conveyed material to ensure a stable and efficient unloading process. 

　　從工作原理來(lái)看，倉(cāng)泵的運(yùn)行緊密依托氣力輸送系統(tǒng)的整體協(xié)作。當(dāng)系統(tǒng)啟動(dòng)后，物料首先從料倉(cāng)落入倉(cāng)泵內(nèi)部，此時(shí)倉(cāng)泵會(huì)先完成進(jìn)料階段，待物料達(dá)到預(yù)設(shè)的裝載量后，進(jìn)料口關(guān)閉，進(jìn)入加壓階段。隨后，來(lái)自氣源裝置的高壓氣體被通入倉(cāng)泵罐內(nèi)，使罐內(nèi)形成一定的壓力，在壓力的作用下，物料被充分流態(tài)化，呈現(xiàn)出類似流體的狀態(tài)。當(dāng)罐內(nèi)壓力達(dá)到設(shè)定值時(shí)，出料閥打開，流態(tài)化的物料便在高壓氣體的推動(dòng)下，沿著輸送管道被輸送至末端的收料倉(cāng)。在整個(gè)輸送過(guò)程中，倉(cāng)泵就像一個(gè) “加壓輸送站”，通過(guò)周期性地完成進(jìn)料、加壓、輸送、排氣等環(huán)節(jié)，實(shí)現(xiàn)物料的連續(xù)或間斷輸送。

　　From the perspective of working principle, the operation of the bin pump relies closely on the overall cooperation of the pneumatic conveying system. After the system is started, the material first falls from the silo into the interior of the silo pump. At this time, the silo pump will complete the feeding stage first. When the material reaches the preset loading capacity, the feeding port will be closed and enter the pressurization stage. Subsequently, high-pressure gas from the gas source device is introduced into the bin pump tank, creating a certain pressure inside the tank. Under the action of pressure, the material is fully fluidized, presenting a fluid like state. When the pressure inside the tank reaches the set value, the discharge valve opens, and the fluidized material is transported along the conveying pipeline to the receiving bin at the end under the push of high-pressure gas. Throughout the entire conveying process, the bin pump acts as a "pressurized conveying station", periodically completing processes such as feeding, pressurization, conveying, and exhaust to achieve continuous or intermittent conveying of materials. 

　　氣力輸送系統(tǒng)一般采用空氣壓縮機(jī)作為氣源，除了倉(cāng)泵，還會(huì)配備高壓旋轉(zhuǎn)閥、螺旋泵等作為供料裝置，它們共同構(gòu)成了完整的物料輸送體系。物料由料倉(cāng)落入供料裝置后，系統(tǒng)向輸送管道內(nèi)輸入高壓氣體，讓氣體和物料充分混合，使物料流態(tài)化，之后通過(guò)高壓氣流將物料輸送到末端收料倉(cāng)，而氣體則經(jīng)分離裝置過(guò)濾后排出大氣，避免對(duì)環(huán)境造成影響。

　　Pneumatic conveying systems generally use air compressors as the gas source. In addition to bin pumps, high-pressure rotary valves, screw pumps, and other feeding devices are also equipped, which together form a complete material conveying system. After the material falls from the silo into the feeding device, the system inputs high-pressure gas into the conveying pipeline to fully mix the gas and material, making the material fluidized. Then, the material is transported to the end receiving silo through high-pressure airflow, and the gas is filtered by the separation device and discharged into the atmosphere to avoid affecting the environment. 

　　倉(cāng)泵的控制系統(tǒng)具有自動(dòng)化程度高的特點(diǎn)，操作起來(lái)十分簡(jiǎn)便，能夠自動(dòng)完成計(jì)量、計(jì)數(shù)、顯示及報(bào)警等功能，大大減少了人工操作的工作量和誤差。同時(shí)，其控制系統(tǒng)用氣、泵頂料倉(cāng)氣化等所需的氣體，不需要另外配備氣源，可直接從系統(tǒng)的氣源裝置獲取，節(jié)省了額外的設(shè)備投入。此外，倉(cāng)泵的密封性良好，運(yùn)行過(guò)程可靠，易損部件較少，這不僅降低了日常維護(hù)的難度，也延長(zhǎng)了設(shè)備的使用壽命，能夠在長(zhǎng)期運(yùn)行中保持穩(wěn)定的輸送效率，滿足工業(yè)生產(chǎn)中對(duì)物料輸送的持續(xù)需求。

　　The control system of the warehouse pump has a high degree of automation, which is very easy to operate. It can automatically complete functions such as metering, counting, display, and alarm, greatly reducing the workload and errors of manual operation. At the same time, the gas required for the control system, pump top silo gasification, etc., does not require an additional gas source and can be directly obtained from the system's gas source device, saving additional equipment investment. In addition, the sealing performance of the warehouse pump is good, the operation process is reliable, and there are fewer vulnerable parts. This not only reduces the difficulty of daily maintenance, but also extends the service life of the equipment, which can maintain stable conveying efficiency in long-term operation and meet the continuous demand for material conveying in industrial production.
