Sealed pump

In the production of chemical industry, there are also powder materials that need to be transported. We enter the transportation of chemical materials through a pneumatic conveying system such as a material sealing pump, which saves a lot of investment than mechanically transporting powder materials. Chemical powder material is a special kind of material, which needs to be transported in a closed environment to avoid chemical reactions due to contact with the air or accidental mixing with other materials. It is often necessary to send gas from one device to another. This requires a sealed environment for conveyance, and the sealed conveyance method of the material seal pump comes in handy. The material seal pump is widely used, and the common types of pneumatic conveying equipment have many structural features, which fully meet the requirements of powder material transportation.
The material sealing pump of pneumatic conveying equipment is composed of a volute casing and an impeller. There are many but short blades on the impeller, and the impeller is directly driven by a motor. Suitable for pneumatic conveying with outlet gauge pressure not greater than 15kpa and compression ratio of 1 ~ 1.15. In this state, the compressor in the sealed pump is divided into a centrifugal blower and a rotary blower. The former has a structure similar to a centrifugal pump, the shell diameter and width are large, and the latter has a similar roots fan and a gear pump. It is suitable for pneumatic conveying with an outlet gauge pressure of 15 ~ 300kp and a compression ratio of less than 4. Vacuum pumps (divided into water ring vacuum pumps and jet vacuum pumps can create vacuum in the pump body of the material seal pump. It is suitable for strong pressure or slightly higher outlet gauge pressure Atmospheric pneumatic conveying, with good control of the air pressure of the material sealing pump , the material being conveyed can be well conveyed, so that the material reaches the specified position. We can also make reasonable air inlet options for the material, such as some If low oxygen transportation is needed, we can add nitrogen or other gases to the transportation process to reduce the chemical reaction of the material in oxygen transportation. For more introduction of transportation methods, please call technical engineers to learn more.
