Installation of material sealing pump

Installation and operation of material sealing pump. Under normal circumstances, it is more suitable for the material sealing pump to be installed at the bottom of the silo, so that the material can be discharged smoothly. 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 installed in 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 seal pump, but the slope of all the inclined pipes should be the same. .
Generally, the material sealing pump can be placed on a hard horizontal surface. There is no need to lay a foundation to install anchor bolts. After the air duct and discharge pipe are 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 material sealing pump (including the ash hopper of the material sealing pump) is generally a minimum and can be appropriately changed according to the actual conditions on site.
The outlet direction of the material seal pump can be determined according to the on-site conditions. Generally, the direction beyond the location of the ash warehouse is appropriate, or it can be determined 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.
It is required that the entire system of the material seal pump and ash conveying pipe be well sealed, and the air leakage rate is less than .%.
Advantages of the material seal pump include long service life, reliable operation, almost no maintenance and wear parts, low equipment investment, small floor space, energy saving and emission reduction.
Problems with single silo pump and negative pressure conveying of fly ash
High power consumption and serious wear and tear
Since the silo pump uses high-pressure air supply, the elbow pipes have serious wear and tear. Welding and repair, frequent replacement, especially the discharge valve, feed valve, and exhaust valve are seriously worn and often stuck. In addition, the three major pneumatic parts are damaged and the repair cost is high. Workers climb on the pump body for repairs. The temperature is high and the environment Harsh and labor-intensive.
, complex operation
Since the warehouse pump adopts automatic control of material level and time, the wiring of the console is complicated and slightly problematic, involving multiple professionals from the three major departments of electrical, thermal engineering, and ash removal maintenance to the ash yard , delaying maintenance time brings a lot of trouble to management, making it difficult to ensure normal production.
, extremely poor environment
Due to the above reasons, in order to ensure operation, there are many emergency repairs, and the equipment leaks dust 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 comprehensive utilization of fly ash, companies have invested heavily in fly ash production lines. However, due to frequent damage to the conveying system, normal production of the air separation equipment system cannot be guaranteed, and some The ash pipe cannot be sent out, which affects the user's ash supply and damages the company's image and interests.
, affecting the normal operation of the sediment tank
Due to the design of ash separation and damage to the warehouse pump, water has to be flushed to the sediment tank, resulting in insufficient water for slag flushing, tight water supply, and due to the small fineness of the ash. It is easy to cause network pipe blockage, valves, and ash pump pipes to become damaged and scrapped, causing serious losses to the entire slag flushing system.
Although the wear of negative pressure conveying is relatively light, the air volume gradually decreases after the fan is used for several years, resulting in the phenomenon of insufficient ash delivery.
Advantages of using material seal pump
Low equipment investment. One material seal pump can replace two silo pumps, reducing equipment investment.
The air pressure of the material sealing pump is. The air supply pressure is reduced, the air consumption is saved, and the motor power is reduced.
, reduce maintenance costs. After the system is installed, debugged and put into operation, it requires basically no operations and almost no maintenance. Maintenance workers only need to perform regular inspections.
, low pressure transportation, good equipment sealing, reliable operation, no pipe blockage, and improved environmental appearance.
