Problems solved by technology
The solid impurities deposited in the dynamic and static ring auxiliary seals will affect the floatability of the seal rings, and the deposition at the bellows will cause "lost bullet" phenomenon, and the medium containing particle impurities directly impacting the sealing end face will cause damage to the sealing end face

The present invention relates to a process pump, in particular to an automatic flushing filter device for the process pump, which comprises a flushing pipe joint and a pump joint, wherein the flushing pipe joint is in threaded connection with the pump joint; and filter screens are respectively arranged in the flushing pipe joint and the pump joint. The automatic flushing filter device has the benefits that the installation and maintenance are convenient, and the life cycle of the mechanical seal can be effectively prolonged. In addition, the filter device has a simple structure, and is low in manufacturing cost and easy to process, and can meet the requirement of filtering medium, thereby saving the material cost and manual maintenance cost of the mechanical seal.
Description
technical field [0001] The invention relates to a process pump, in particular to an automatic flushing and filtering device for the process pump. Background technique [0002] The process pump is a commonly used pipeline transportation device. The process pump currently used is suitable for transporting media that does not contain solid particles. When using it, it is found that the replacement cycle of the mechanical seal is relatively fast. The cause of the failure of the mechanical seal is analyzed: the reason for the failure of the mechanical seal itself is excluded, and it is considered to be Since the flushing medium contains particulate impurities, the particulate impurities entering the sealing cavity will scratch the sealing surface, and the fibrous material entering the sealing cavity will also damage the liquid film on the sealing surface. Solid impurities deposited on the auxiliary seals of the dynamic and static rings will affect the floatability of the seal rin...
