Specification

Equipment installation 

1. In general, it is appropriate to install the material seal pump at the bottom of the material warehouse, and the blanking is smooth. If it cannot be placed at the bottom of the silo, it can also be placed aside. However, the angle of blanking pipe shall be ≥ 45 °. If it is installed at the lower part of the electrostatic precipitator ash hopper, one bucket and one pump can be used, or two buckets, two inclined pipes and one pump can be used; Under special circumstances, four buckets and four inclined pipes can also be inserted into a material seal pump, but the inclination of all ash falling inclined pipes shall be ≥ 45 °.

2. Generally, the material seal pump can be placed on the hard horizontal ground without foundation and anchor bolts. When the air duct and discharge pipe are connected, they can be put into operation. However, a flexible joint shall be installed when the air inlet pipe is connected with the pump pipe.

3. The total height of the material seal pump (including the ash hopper of the material seal pump) is generally 3.5-4.5m, which can be changed according to the actual situation on site.

4. The outlet direction of the material seal pump can be determined according to the site situation. Generally, it is better to go beyond the direction where the ash silo is located, or according to the direction of the pipeline.

5. The device requires that the gas emission of the dust collector on the top of the silo shall be greater than the total amount of air carried by the material seal pump. The positive pressure shall not occur in the silo to avoid affecting the operation of the ash conveying system.

6. The air source, material seal pump and ash conveying pipe shall be well sealed, and the air leakage rate shall be less than 0.2%.
