| Abstract: | The sealing of the intermediate rod on a reciproceating pump is of great importance. Thereby a new full floating seal assembly for the intermediate rod is developed. The center of the seal assembly can be adjusted automaically with the rod in operation to keep the center line of the oil seal coinside with the center of the rod permanently. The result of the field test shows that, by using the new sealing assembly, the oil seal wear caused by offset can be effectively prevented, therefore the service life of the oil seal can be improved and better sealing effect can be achieved. |
