倉(cāng)泵，作為氣力輸送系統(tǒng)的核心設(shè)備，廣泛應(yīng)用于電力、化工、冶金、建材等領(lǐng)域，其作用是通過(guò)壓縮空氣將粉狀或顆粒狀物料高效輸送至指定位置。根據(jù)不同的分類(lèi)標(biāo)準(zhǔn)，倉(cāng)泵可劃分為多種類(lèi)型，每種類(lèi)型在設(shè)計(jì)原理、適用場(chǎng)景及性能特點(diǎn)上均有顯著差異。以下從工作原理、結(jié)構(gòu)特征、輸送壓力、應(yīng)用領(lǐng)域等維度，詳細(xì)解析倉(cāng)泵的主要類(lèi)型。

　　Warehouse pumps, as the core equipment of pneumatic conveying systems, are widely used in fields such as electricity, chemical engineering, metallurgy, and building materials. Their function is to efficiently transport powdered or granular materials to designated locations through compressed air. According to different classification criteria, bin pumps can be divided into multiple types, each with significant differences in design principles, applicable scenarios, and performance characteristics. The following provides a detailed analysis of the main types of bin pumps from dimensions such as working principles, structural characteristics, conveying pressure, and application fields.

　　按工作原理與結(jié)構(gòu)特征分類(lèi)，倉(cāng)泵可分為上引式與下引式兩大類(lèi)。上引式倉(cāng)泵的進(jìn)料閥位于設(shè)備頂部，排氣閥則設(shè)置在側(cè)壁或底部。工作時(shí)，物料從頂部進(jìn)入泵體，壓縮空氣從底部或側(cè)部注入，推動(dòng)物料向上流動(dòng)并形成懸浮狀態(tài)，最終通過(guò)輸送管道排出。其優(yōu)勢(shì)在于進(jìn)料順暢、排氣徹底，尤其適用于易結(jié)塊或粘性較大的物料。下引式倉(cāng)泵的進(jìn)氣口則位于設(shè)備底部，物料從頂部加入后，在重力作用下自然堆積于泵體下部。壓縮空氣從底部進(jìn)入，將物料吹散并形成流態(tài)化，沿管道輸送。此類(lèi)倉(cāng)泵結(jié)構(gòu)簡(jiǎn)單、能耗較低，但對(duì)物料的流動(dòng)性要求較高，若物料含水量過(guò)高或粒度不均，易導(dǎo)致堵塞。

　　According to the working principle and structural characteristics, bin pumps can be classified into two categories: upward and downward. The feed valve of the upward suction bin pump is located at the top of the equipment, while the exhaust valve is set on the side wall or bottom. During operation, materials enter the pump body from the top, and compressed air is injected from the bottom or sides to push the materials upward and form a suspended state, ultimately being discharged through the conveying pipeline. Its advantage lies in smooth feeding and thorough exhaust, especially suitable for materials that are prone to clumping or have high viscosity. The inlet of the down drawn bin pump is located at the bottom of the equipment, and after the material is added from the top, it naturally accumulates at the lower part of the pump body under the action of gravity. Compressed air enters from the bottom, blows the material into a fluidized state, and transports it along the pipeline. This type of warehouse pump has a simple structure and low energy consumption, but requires high fluidity of the material. If the material has a high water content or uneven particle size, it is easy to cause blockage.

　　按輸送壓力范圍分類(lèi)，倉(cāng)泵可分為低壓、中壓與高壓三種類(lèi)型。低壓倉(cāng)泵的輸送壓力通常在0.1至0.2兆帕之間，適用于短距離、低阻力的輸送場(chǎng)景，如廠區(qū)內(nèi)物料轉(zhuǎn)運(yùn)。其特點(diǎn)是設(shè)備體積小、投資成本低，但輸送效率有限。中壓倉(cāng)泵的輸送壓力范圍為0.2至0.6兆帕，能夠應(yīng)對(duì)中等距離的輸送需求，如從倉(cāng)庫(kù)到生產(chǎn)車(chē)間的物料供應(yīng)。此類(lèi)倉(cāng)泵在能耗與效率之間取得平衡，是應(yīng)用最廣泛的類(lèi)型。高壓倉(cāng)泵的輸送壓力可達(dá)0.6兆帕以上，專(zhuān)為長(zhǎng)距離、高阻力或特殊物料輸送而設(shè)計(jì)，如跨區(qū)域粉煤灰輸送。其設(shè)備強(qiáng)度高、密封性能好，但制造與維護(hù)成本也相應(yīng)增加。

　　According to the range of conveying pressure, bin pumps can be classified into three types: low pressure, medium pressure, and high pressure. The conveying pressure of low-pressure bin pumps is usually between 0.1 and 0.2 megapascals, suitable for short distance, low resistance conveying scenarios, such as material transfer within the factory area. Its characteristics are small equipment size, low investment cost, but limited conveying efficiency. The delivery pressure range of the medium pressure warehouse pump is 0.2 to 0.6 megapascals, which can meet the demand for medium distance transportation, such as material supply from warehouses to production workshops. This type of warehouse pump achieves a balance between energy consumption and efficiency, and is the most widely used type. The conveying pressure of the high-pressure bin pump can reach over 0.6 megapascals, designed specifically for long-distance, high resistance, or special material conveying, such as cross regional fly ash conveying. Its equipment has high strength and good sealing performance, but the manufacturing and maintenance costs also increase accordingly.

　　按物料輸送方式分類(lèi)，倉(cāng)泵可分為連續(xù)式與間歇式。連續(xù)式倉(cāng)泵通過(guò)恒定的壓縮空氣流量，實(shí)現(xiàn)物料的持續(xù)、穩(wěn)定輸送。此類(lèi)設(shè)備適用于大規(guī)模、連續(xù)性生產(chǎn)場(chǎng)景，如水泥廠生料輸送。其優(yōu)勢(shì)在于輸送效率高、自動(dòng)化程度高，但對(duì)系統(tǒng)穩(wěn)定性要求嚴(yán)格，一旦出現(xiàn)故障可能導(dǎo)致整個(gè)生產(chǎn)線停機(jī)。間歇式倉(cāng)泵則采用周期性進(jìn)料與輸送模式，即每次進(jìn)料后，通過(guò)脈沖式壓縮空氣將物料一次性排出。此類(lèi)設(shè)備適用于小批量、多品種物料輸送，如實(shí)驗(yàn)室樣品分析。其特點(diǎn)是操作靈活、適應(yīng)性強(qiáng)，但輸送效率相對(duì)較低。

　　According to the material conveying method, warehouse pumps can be classified into continuous and intermittent types. Continuous bin pumps achieve continuous and stable transportation of materials through a constant compressed air flow rate. This type of equipment is suitable for large-scale, continuous production scenarios, such as raw material conveying in cement plants. Its advantages lie in high conveying efficiency and high degree of automation, but it has strict requirements for system stability. Once a fault occurs, it may cause the entire production line to shut down. The intermittent bin pump adopts a periodic feeding and conveying mode, that is, after each feeding, the material is discharged in one go through pulse compressed air. This type of equipment is suitable for small batch and multi variety material transportation, such as laboratory sample analysis. Its characteristics are flexible operation and strong adaptability, but the conveying efficiency is relatively low.

　　按應(yīng)用領(lǐng)域與行業(yè)特性分類(lèi)，倉(cāng)泵可分為通用型與專(zhuān)用型。通用型倉(cāng)泵設(shè)計(jì)標(biāo)準(zhǔn)統(tǒng)一，可滿足大多數(shù)常規(guī)物料的輸送需求，如糧食、塑料顆粒等。其結(jié)構(gòu)簡(jiǎn)單、價(jià)格親民，是市場(chǎng)上的主流產(chǎn)品。專(zhuān)用型倉(cāng)泵則針對(duì)特定行業(yè)或物料特性進(jìn)行優(yōu)化設(shè)計(jì)，如電力行業(yè)的粉煤灰輸送倉(cāng)泵，需具備耐高溫、耐磨損等特性；化工行業(yè)的原料輸送倉(cāng)泵，則需滿足防爆、耐腐蝕等要求。此類(lèi)設(shè)備技術(shù)含量高、定制化程度強(qiáng)，通常由專(zhuān)業(yè)廠商根據(jù)用戶需求定制生產(chǎn)。

　　According to the application field and industry characteristics, warehouse pumps can be classified into universal and specialized types. The universal bin pump has a unified design standard and can meet the transportation needs of most conventional materials, such as grain, plastic pellets, etc. Its structure is simple and its price is affordable, making it the mainstream product in the market. Specialized silo pumps are optimized for specific industries or material characteristics, such as the fly ash conveying silo pump in the power industry, which needs to have high temperature resistance, wear resistance and other characteristics; The raw material conveying bin pumps in the chemical industry need to meet requirements such as explosion prevention and corrosion resistance. This type of equipment has high technological content and strong customization, usually produced by professional manufacturers according to user needs.

　　倉(cāng)泵的類(lèi)型多樣，選擇時(shí)需綜合考慮物料特性、輸送距離、生產(chǎn)規(guī)模及成本預(yù)算等因素。隨著氣力輸送技術(shù)的不斷發(fā)展，倉(cāng)泵的性能將持續(xù)優(yōu)化，應(yīng)用領(lǐng)域也將進(jìn)一步拓展。

　　There are various types of warehouse pumps, and when selecting, factors such as material characteristics, conveying distance, production scale, and cost budget should be comprehensively considered. With the continuous development of pneumatic conveying technology, the performance of bin pumps will continue to be optimized, and their application fields will also be further expanded.
