Pumping machine and pumping system thereof

The utility model discloses a pumping system and a pumping machine. The pumping system comprises a driving device, a conveying cylinder, a push rod and a piston. The push rod is provided with a lubrication channel, the piston is provided with a lubrication opening, the push rod is sleeved with a lubricating sleeve ring capable of relatively rotating, and the lubricating sleeve ring is provided with a supply channel matched with the inlet end of the lubrication channel and can perform telescopic movement along with the push rod. According to the pumping system, by arranging the lubricating sleeve ring, a lubricating medium can enter the lubrication channel through the supply channel of the lubricating sleeve ring, and the lubricating sleeve ring can perform telescopic movement along with the push rod and can rotate relative to the push rod; when the push rod rotates in the operation process, the lubricating sleeve ring does not rotate along with the push rod, so that a lubricating hose connected to the lubricating sleeve ring cannot rotate along with the push rod and is prevented from being wound around the push rod, and the problem that lubrication is unsmooth due to the fact that the hose is wound around the push rod is solved.
