　　供料器與料封泵的介紹

　　Introduction to feeders and sealing pumps

　　旋轉供料器加工精度高，具有鎖氣功能，旋轉供料器又稱為旋轉閥、鎖氣閥，通常旋轉供料器的構造，是有數個葉片的轉子，在固定機殼內部的旋轉轉動，下去的物料填充在各個葉片相互間，伴隨著葉片的轉動，將物料輸送下去，其首要的作用的是輸送物料和控制物料的輸送。旋轉供料器加工精度高，具有鎖氣功能。料封泵是一種粉體氣力輸送設備，屬于低壓稀相輸送類別，利用高速氣流的引射作用來輸送粉狀物料，在當量距離450m，提升高度40m范圍內使用效果最佳。目前廣泛應用于粉煤灰、氧化鋁粉、干窯灰、焦粉、水泥粉料等干燥松散粉料的中短距離輸送。

　　The rotary feeder has high processing accuracy and air locking function. The rotary feeder, also known as the rotary valve or air lock valve, is usually constructed with a rotor with several blades that rotate inside a fixed casing. The material that goes down is filled between the blades, and along with the rotation of the blades, the material is transported down. Its primary function is to transport and control the transportation of materials. The rotary feeder has high processing accuracy and air locking function. Material sealing pump is a type of powder pneumatic conveying equipment, belonging to the category of low-pressure dilute phase conveying. It uses the injection effect of high-speed airflow to transport powdered materials, and has the best performance within an equivalent distance of 450m and a lifting height of 40m. At present, it is widely used for medium to short distance transportation of dry and loose powder materials such as fly ash, alumina powder, dry kiln ash, coke powder, cement powder, etc.

　　The difference between feeder and sealing pump

　　01輸送量與輸送距離一般情況下旋轉供料器與料封泵的氣源均為羅茨風機。所以輸送量是差不多的。旋轉供料器的輸送距離最佳距離為45-75m，最遠距離為300m。料封泵輸送距離約為30-500m。02工作壓力料封泵與旋轉供料器通常采用羅茨風機供氣，工作壓力一般在0.1Mpa以下 。03工作方式旋轉供料器與料封泵工作采用連續式工作,工作過程中進料和輸送同時進行。04輸送濃度旋轉供料器為懸浮流稀相輸送，物料為懸浮狀態，基本不會引起管道堵塞 料封泵只能進行低濃度輸送。在輸送過程中,必須防止因濃度升高而引起管道堵塞或吹穿料封層。05輸送速度旋轉供料器為稀相輸送，輸送速度比料封泵更快一點。旋轉供料器對管道的磨損要比料封泵稍大，但是差別不大。06輸送管道旋轉供料器可以多個下料口共管。料封泵一般不能多泵共管,只能一臺泵一根輸送管,當有多個下料口時管道布置復雜。?07價格同樣輸送量的旋轉供料器的價格相比料封泵要便宜很多。并且因為旋轉供料器的各種優勢，很多廠家已經在對料封泵進行了替換。在行業內也慢慢更傾向于選擇旋轉供料器來進行氣力輸送的設計。

　　Under normal circumstances, the air source for both the rotary feeder and the material sealing pump is a Roots blower. So the conveying capacity is similar. The optimal conveying distance of the rotary feeder is 45-75m, with a maximum distance of 300m. The conveying distance of the material seal pump is about 30-500m. The working pressure of the material seal pump and the rotary feeder is usually supplied by a Roots blower, and the working pressure is generally below 0.1Mpa. 03 Working mode: The rotating feeder and material sealing pump work continuously, with feeding and conveying carried out simultaneously during the working process. The 04 concentration rotary feeder is used for suspended flow dilute phase transportation, and the material is in a suspended state, which basically does not cause pipeline blockage. The material sealing pump can only carry out low concentration transportation. During the transportation process, it is necessary to prevent pipeline blockage or blowing through the sealing layer due to increased concentration. The 05 conveying speed rotary feeder is for dilute phase conveying, and the conveying speed is slightly faster than that of the material sealing pump. The wear on the pipeline caused by the rotating feeder is slightly greater than that of the sealing pump, but the difference is not significant. The 06 conveying pipeline rotary feeder can share multiple discharge ports. Material sealing pumps generally cannot have multiple pumps sharing the same pipe, and can only have one pump and one conveying pipe. When there are multiple discharge ports, the pipeline layout is complex.? The price of a rotary feeder with the same conveying capacity is much cheaper compared to a sealed pump. And due to the various advantages of the rotary feeder, many manufacturers have already replaced the material seal pump. In the industry, there is also a growing tendency to choose rotary feeders for pneumatic conveying design.
