Jet pump

The jet pumps produced by Gongyi Fucheng are not restricted by terrain, ground features, and height differences, and transport cement, raw materials, and fly ash. The process of powdery materials such as coal ash is completely closed and pollution-free, which minimizes the damage to the environment. The equipment has a simple structure and small maintenance. The jet pump equipment is a new type of low-pressure continuous conveying equipment. This powder conveying equipment can be widely used in industries such as electric ash removal, building material transfer, large construction sites and other industries.
Fucheng Machinery has three types of powder conveying jet pumps that use the air flow to transport loose materials along the pipeline: suction, pressure, and hybrid. For powder long-distance conveying equipment used in powder conveying applications, There is a good use effect in the construction, and its working principle is to use the kinetic energy of the airflow to make the granular material in a suspended state and transport it along the pipeline with the airflow :
Jet pump suction type. After the exhaust fan is started, the entire system assumes a certain degree of vacuum. Under the action of pressure difference, air flows into the suction nozzle and is sent along the conveying pipe to the separator at the discharge position. After being separated in the stream, it is discharged from the bottom of the separator, and the air stream is purified by the dust collector and then discharged into the atmosphere through the muffler. The advantage is that the supply is simple and the material can be sucked from several places at the same time. .
Jet pump pressure feed type, the blower presses the air into the conveying pipe, the material is supplied from the feeder, the mixture of air and material is pressured along the conveying pipe to the unloading place , the material is discharged after the separator, and the air is removed by dust The purifier is discharged into the atmosphere after purification. Its characteristics are opposite to that of the suction type . It can transport materials to several places at the same time . The conveying distance is longer, the productivity is higher, but the structure is complicated.
The injection pump constructed by Fucheng Machinery can also achieve the purpose of mixed conveyance through reasonable pneumatic mixing calculation, thus achieving the ideal powder conveying application. This technology is also widely used in the construction of material-sealed pumps .
Fucheng Machinery, the technology of powder conveying jet pump, summarizes it for everyone, so that the powder materials can reach the long-distance conveying application in the pipeline of the jet pump.
1. Material transportation : dry powdery materials, the surface moisture is allowed to be about 0 , 8% , otherwise it will cause stagnation or even blockage.
2. Conveying capacity : The conveying capacity of the chute is affected by many factors and often changes greatly. The table below shows the conveyance of cement and raw materials at 6% and 10% slope for reference.
3 , the slope : the slope of the chute can be changed within the range of 6% -14% , where the installation space allows, it is advantageous to use a larger slope,
4. Air volume: Air volume is affected by factors such as material status, chute slope, and ventilation layer conditions. It can vary between 1 , 5-3m3 / min . Generally, 2m3 / min can be considered.
5. Wind pressure : The wind pressure of the chute is generally between 400-600mm water column. Larger long chute should take a larger value.

The material enters the chamber from the airlock uniformly and in a constant amount, and after fluidizing once through the fluidization box, a negative pressure zone is formed between the nozzle and the inner venturi tube, and the fluidized stream is rolled into the mixing tube, and then Deceleration and pressure increase through the diffusion pipe section, so that the material is delivered to its destination.
