1.Pneumatic conveyor with delivery压送式气力输送机

The working principle of工作原理
由于高压气体的作用，物料从发送罐进入输送管，压缩气体经电磁阀的开闭形成脉冲气流，（气刀）当气刀压力大于发送罐压力时，气流将物料切割成料，依靠料栓前后的静压差作推动力，将物料推向前进，到达分离装置实施料气离后，物料落入料仓，气体排入大气实现输送。Due to the effect of high pressure gas, material from sent tanks into the duct, compressed gas by the solenoid valve opening and closing of the pulse jet formation, (air knife) when air blade pressure is greater than send tank pressure, airflow to the material cutting ChengLiao, rely on the material before and after the static pressure difference as a driving force of bolt, the material forward, reach the separation device to implement material gas, after the material into the bin, gas atmosphere  implementation.

6、维护要求很高对维护技术人员的素质要求亦很高。

1, delivery speed, smaller pipe less wear and tear.
2, control must be automated, high to the requirement of all kinds of electrical components.
3, long transmission distance, can reach more than 1000 m.
4, can fill in conveying tube peripherals trachea, and use a variety of ways to fill gas,but electric control complex.  
5, send tank (also known as warehouse pump) is a pressure vessel, for mandatory sign equipment.
6, a high maintenance requirements in maintaining the quality requirements of technical personnel is also very high.

2.Carrying the pneumatic conveyor吸送式气力输送机

The working principle of工作原理

吸送气力输送一般用罗茨真空泵作动力源，将管路及罐式仓抽成一定的真空状态促成进风口在大气压的作用下形成物料粉粒料与气体的两相流，经输送管道输入旋风分离器。两相流在旋风分离器内由于离心力及重力作用下，使大部分物料与气体分离。少量的物料与气体进入除尘器。通过滤袋作用使粉料与气体分离。气体排入大气。

Carrying the pneumatic conveying roots vacuum pump as power source, is commonly used in the pipeline and tank storage into a vacuum state  to air inlet formed under the action of atmospheric pressure, material powder material and the two phase flow of gas, the pipeline type cyclone separator.Two phase flow in the cyclone separator due to centrifugal force and gravity, so most of the material and gas separation.A small amount of material and gas into the dust.Through the filter bag make powder and gas separation.Gas discharged into the atmosphere.

 The characteristics of优势
1，环保、可靠性最好，管路内的粉尘不会泄漏于环境。

2、设备的制造、维护要求低，工人的可操作性强。

3、使用的压力(真空度)小，安全性高。

4、气体(一般为气体)取自大气，气体的温度即为当时当地的气温，对热敏性物料尤为适宜。

5、输送为连续式、亦可间断，管道内无积存。

6、易实现多点进料，多点卸料的输送工程目标。

7、气体动力源一般为离心风机、罗茨风机(泵)，使用寿命长

 8、适宜短距离输送一般不超过100m。

9、对管道的密封要求高不得漏气。

10、对输送物料的应性强粉料、颗粒料均可顺利输送。

1, environmental protection, reliability, best line in the dust will not leak in the environment.
2, equipment manufacturing, and low maintenance requirements, the maneuverability of the workers.
3, using small pressure (vacuum), high safety.
4 (general) for gas, gas from the atmosphere, the temperature of the gas is at that time, the local temperature, particularly suitable for heat-sensitive materials.
5, a continuous conveying for continuous, also no accumulated in the pipe.
6, easy to implement multipoint feeding and multipoint discharge goal in transportation engineering.
7, gas power source is commonly centrifugal blower, roots blower (pump), long service life
8, suitable for short distance transportation  is generally not more than 100 m.

3、Hybrid pneumatic conveyor混合式气力输送机
The working principle of工作原理
在通过吸嘴抽一部分材料与空气混合物吸喂食管,然后分离器的材料和流动分离。材料然后通过分离器的底部放电器,和交付给料机的一部分。放电,在交付运输管道的一部分。和空气的尘埃风机压力进入输送管道的一部分。然后用材料,混合输送物质的形式交付In pumping part through the suction nozzle material in mixture with air suction feeding tube, then the separator materials and the flow separation.Material then through a discharger at the bottom of the separator, and delivery part of the feeder. Discharge, and into the delivery part of the transporting pipe.And the air out of the dust  the fan pressure into the part of thetransporting pipe. Then mixed with material, conveying material in the form of delivery.
