>Installation operation of material seal pump. Generally, it is more suitable for the material seal pump to be installed at the bottom of the silo for smooth material discharge. If it is not placed at the bottom of the library, it can be placed next to it. But the blanking tube is beveled. If it is installed at the lower part of the electrostatic precipitator, one bucket and one pipe can be used. In special cases, four buckets and four inclined pipes can be inserted into a material sealing pump. However, the slope of all the ash falling inclined pipes should be the same.
> The material seal pump is generally placed on a hard horizontal surface and can be put into operation without laying a foundation to install anchor bolts. After the air duct discharge pipe is connected, it can be put into operation. However, a flexible joint should be installed when connecting the air inlet pipe to the pump.
>The total height of the sealing pump (including the ash hopper of the sealing pump) is generally... - It can be changed appropriately according to the actual situation on site.
>The direction of the outlet of the material seal pump can be determined according to the site conditions. Generally, the direction beyond the location of the ash warehouse is appropriate or according to the direction of the pipeline.
>. This device requires that the gas emission volume of the dust collector on the top of the warehouse is slightly larger than the total air volume of the shoe material pump. Do not allow positive pressure to occur in the warehouse to avoid affecting the operation of the ash conveying system.
>. Origin of requirements: The entire system of material seal pump and ash conveying pipe is well sealed and the air leakage rate is less than .%.
>Advantages of the material seal pump: long service life, reliable operation, almost no maintenance and wear parts, less investment in equipment, small footprint, energy saving and emission reduction.
>Problems with a single silo pump and negative pressure transport of fly ash
>High power consumption and serious wear
>Since the silo pump uses a high-pressure gas supply elbow pipe Badly worn. Frequent wear and tear, welding, repair and replacement, especially the discharge valve, feed valve, and exhaust valve are severely worn and often stuck. In addition, the three major parts of the pneumatic are damaged and the maintenance cost is high. Workers rush to repair the pump body. The temperature is high and the environment is harsh and labor-intensive.
>. Complex operation
>Because the warehouse pump adopts material level and time automatic control console, the wiring is complicated, and slight problems involve multiple professionals from the three major departments of electrical, thermal, and ash removal maintenance to the ash yard. Delayed maintenance time brings a lot of trouble to management and makes it difficult to ensure normal production.
>. The environment is extremely poor
>Due to the above reasons, in order to ensure frequent emergency repairs, the equipment leaks ash everywhere, endangering the environment of the factory and the living environment of the surrounding people, and has a great impact on civilized production.
>, Affecting the comprehensive utilization of fly ash
>In order to carry out the comprehensive utilization of fly ash, enterprises have invested heavily in fly ash production lines. However, due to frequent damage to the transportation system, normal production of the air separation equipment system cannot be guaranteed. There are ash pipes. Failure to deliver will affect user supply and harm the company's image and interests.
>, affecting the normal operation of the sediment tank
>Due to the design of ash and slag separation, after the warehouse pump is damaged, water has to be flushed to the sediment tank, resulting in insufficient flushing water and tight water supply. Due to the small ash fineness, it is easy to cause network management problems. Blockage, valves, and ash pump pipelines were damaged and scrapped, causing serious losses to the entire slag flushing system.
> Although the wear of negative pressure conveying is relatively light, the gradual reduction of air volume after several years of use of the fan may cause the ash to be insufficiently delivered.
>Advantages of using material sealing pumps
>Low equipment investment. One material sealing pump can replace two silo pumps, reducing equipment investment.
>. The air pressure of the material seal pump is -. Reducing the air supply pressure saves air consumption and reduces the motor power.
>, Reduced maintenance costs. After the system is installed, debugged and put into operation, there is basically no operation and almost no maintenance required. Maintenance workers only need to perform regular inspections.
>The low-pressure conveying equipment has good sealing, reliable operation and no pipe blockage, and the environmental appearance has been improved.
