Material seal pump structure material seal pump structure diagram

Sealing pump is a new type of jet injection jet pump. Sealing pump structure mainly includes reduction gear, material cylinder, injection tube, nozzle, diffuser and fluidization chamber. Schematic diagram of the material seal pump first jet pipe air or air and material mixture into the air nozzle. The nozzle converts the pressure of the air into kinetic energy of the air, which causes a partial negative pressure near the exit of the nozzle by the action of the air flow, aspirates the material into the conveying pipe and converts the kinetic energy of the air into pressure in the diffuser pipe. Gear reducer to adjust the position of the nozzle, in order to adjust the amount of material delivered. The fluidization chamber at the bottom of the barrel can partially fluidize the material of the barrel to facilitate material delivery. In addition to the material conveying pump, the material energy is also an important influencing factor in addition to the aerodynamic energy. The material level is high, the potential energy is large and the conveying capacity is correspondingly large, on the contrary, it is small. However, different applications or application of material seal pump structure is not the same. For example, there is difference between the low-pressure feed material seal pump structure and the cement feed material seal pump structure. Cement Conveying Material Sealing Pump Structure Cement Conveying Material Sealing pump has the advantages of simple structure, convenient operation, small maintenance, continuous and continuous conveying, automatic output adjustment of equipment, good effect of sending ash, low pressure of gray medium, Pipeline valves should not be worn. Equipment costs lower than other transportation equipment, the latter part of the operation basically no maintenance. Low-pressure feed material seal pump structure Low-pressure feed material seal pump structure includes: 1. Diffuser; 2. Cleaning valve; 3. Pump body; 4. Under the air box; 5. Tuyere; 6. Pressure gauges; Air valve 8 jet pipe 9 rack 10 adjustment device 11 intake manifold 12 check valve. Low-pressure feed material sealing pump tuyere designed to move through the adjustment device (gear, rack) to reciprocate the jet pipe, the distance moved by the wind pressure and adjust the dial on the device control. Pump does not work, the nozzle position A, when the pump work, the first open source cleaning pipe, and then through the adjustment device to the nozzle to the desired location, such as the location B. When the bunker arch phenomenon occurs, you can open the 13 intake valve purge. (Editor: Zhuang Ling)
