[0002] The oil pump is a kind of machine equipment for oil extraction, also known as the kowtow machine. The oil pump is the most important lifting equipment in the rod pumping system. Depending on whether there is a walking beam, it can be divided into a walking beam type oil pump and a beamless type oil pump.
