dry screw vacuum pump purification process

The purification and cleaning of screw vacuum pump is to remove the gas and compressed steam remaining in the dry screw vacuum pump during compression. When the dry screw vacuum pump is restarted, these residual materials may cause motor overload, which may produce excessive friction load or damage the screw or pump body. Therefore, in the case of a considerable amount of dirty substances in the pump, the pump should be cleaned.

The purpose of cooling and purification is to cool the pump body and screw. When the pump is running, the screw rotation makes the pumped gas enter the pump cavity and compress to the exhaust end. Due to the hot compression, the gas temperature will rise rapidly. In order to prevent the pump from being damaged, these heat must be eliminated immediately. For small screw vacuum pump, cooling purification is optional.

Air in the atmosphere is usually used as the cooling and purification medium. When the extracted process gas is not suitable for air purification, other cooling media, such as nitrogen, clean and dry air, should be used. For standard pumps, an interface is provided near the exhaust end of the pump body.
