　　供料器与料封泵的介绍

　　Introduction to feeders and sealing pumps

　　旋转供料器加工精度高，具有锁气功能，旋转供料器又称为旋转阀、锁气阀，通常旋转供料器的构造，是有数个叶片的转子，在固定机壳内部的旋转转动，下去的物料填充在各个叶片相互间，伴随着叶片的转动，将物料输送下去，其首要的作用的是输送物料和控制物料的输送。旋转供料器加工精度高，具有锁气功能。料封泵是一种粉体气力输送设备，属于低压稀相输送类别，利用高速气流的引射作用来输送粉状物料，在当量距离450m，提升高度40m范围内使用效果最佳。目前广泛应用于粉煤灰、氧化铝粉、干窑灰、焦粉、水泥粉料等干燥松散粉料的中短距离输送。

　　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.

　　01输送量与输送距离一般情况下旋转供料器与料封泵的气源均为罗茨风机。所以输送量是差不多的。旋转供料器的输送距离最佳距离为45-75m，最远距离为300m。料封泵输送距离约为30-500m。02工作压力料封泵与旋转供料器通常采用罗茨风机供气，工作压力一般在0.1Mpa以下 。03工作方式旋转供料器与料封泵工作采用连续式工作,工作过程中进料和输送同时进行。04输送浓度旋转供料器为悬浮流稀相输送，物料为悬浮状态，基本不会引起管道堵塞 料封泵只能进行低浓度输送。在输送过程中,必须防止因浓度升高而引起管道堵塞或吹穿料封层。05输送速度旋转供料器为稀相输送，输送速度比料封泵更快一点。旋转供料器对管道的磨损要比料封泵稍大，但是差别不大。06输送管道旋转供料器可以多个下料口共管。料封泵一般不能多泵共管,只能一台泵一根输送管,当有多个下料口时管道布置复杂。?07价格同样输送量的旋转供料器的价格相比料封泵要便宜很多。并且因为旋转供料器的各种优势，很多厂家已经在对料封泵进行了替换。在行业内也慢慢更倾向于选择旋转供料器来进行气力输送的设计。

　　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.
