Abstract | The utility model relates to the technical field of oil extraction processes, in particular to a self-lubricating packing box of an oil pumping unit, which is characterized in that a first annular cavity between a packing box gland and a polish rod and a second annular cavity between the packing box gland and a packing box pressing cap are filled with lubricating oil; lubricating oil in the second annular cavity enters the first annular cavity through the second oil flow channel, lubricating oil in the first annular cavity enters the second annular cavity through the first oil flow channel, and internal and external circulation is formed. When the polish rod moves downwards, lubricating oil in the second annular cavity enters the first annular cavity through the first oil flow channel, lubricating oil in the first annular cavity enters the second annular cavity through the second oil flow channel, external and internal circulation is formed, and it is always guaranteed that the lubricating oil in the first an |
