Dalian 300*300 discharge valve cast steel star unloader wear-resistant welded star

The material is discharged at the discharge port of the unloader installed under negative pressure. The upper part receives the material discharged from the unloader. The rotating impeller plays the role of transporting the material and is also responsible for sealing to prevent the pneumatic conveying process. Air is sucked in from the discharge port to ensure normal discharge of the ash discharge valve. The ordinary type can be used on ordinary materials below
temperature and at normal temperature. It can continuously and evenly supply materials into the conveying pipe. material, and in the system and separation dust collection department, it can also function as an unloader.
The pressure type adopts a closed rotor and can be widely used in suction-type and pressure-type air flow conveying systems and negative pressure conveying equipment. It can ensure that the air flow pressure in the conveying pipe does not leak and can safely convey and collect. The material is knotted, so it is called a million-lock air device in this regard. It can not only withstand pressure, but also has ordinary functions.
The high-temperature type is based on the different temperature rises of the material conveying and the unloading port. Because the temperature has an impact on the expansion of the machine body and is detrimental to the bearing and oil seal system, our factory has designed a high-temperature-resistant external structure star unloader< br/>, it separates the running part from the box part in contact with the material, and can safely keep the bearing operation and oil seal system from being affected by cross-temperature and working normally. This type of product is not only resistant to high temperatures, but can also be used to protect against heat absorption. It has a very good effect in conveying and receiving non-toxic materials and metallic powders. Because this type of object has penetrating properties, the material penetrates the oil seal device and goes straight into the bearing, causing the machine to run uninhibited and damage the machine. It is precisely because of the characteristics of external packaging that it does not Will come into contact with materials.
