The working principle of the material sealing pump is to use the action of airflow jet to drive the ash particles to the ash silo. The material sealing pump mainly consists of four parts: nozzle, cylindrical pump body, nozzle adjustment device, and bottom vaporization device. The energy of the material sealing pump during operation comes from two parts: one is the kinetic energy of the fan, and the other is the potential energy of the material column. The height of the material column, the potential energy, the pressure, and the corresponding conveying capacity are high, and vice versa, they are small. When the material sealing pump is working normally, it maintains a certain level of material height. When the electric dust discharge volume increases in a short period of time while the material sealing pump is still working normally, the level height naturally increases. As the level height increases, the material pressure increases, the potential energy increases, and the conveying capacity increases accordingly until the system automatically balances. When the electric dust discharge volume decreases in a short period of time while the material sealing pump is still working normally, the level height naturally decreases. As the level height decreases, the potential energy decreases, and the conveying capacity decreases accordingly until the system automatically balances.
performance advantages
1. The equipment investment is small, and one material sealing pump can replace two bin pumps, reducing equipment investment.
2. The gas pressure of the material sealing pump is 0.04Mpa-0.1Mpa, which reduces the gas supply pressure, saves gas consumption, and reduces motor power.
3. Reduced maintenance costs. After the system is installed, debugged, and put into operation, there is basically no need for operation and almost no maintenance. Maintenance workers only need to conduct regular inspections.
4. Low pressure conveying, good equipment sealing, reliable operation
