Description

Technical Field

[0002] The oil pump is a kind of machine equipment for oil extraction, commonly known as "kowtow machine". The oil pump is the most important lifting equipment in the rod pumping system. The walking beam type oil pump is powered by the power machine, and the high-speed rotation of the power machine is converted into the low-speed rotation of the crank of the oil pump through the reducer, and the rotational motion is converted into the up and down reciprocating motion of the donkey head of the oil pump by the crank-connecting rod-walking beam mechanism, and the deep well pump is driven to work through the suspension rope assembly. Since the oil pump has been running in the oil field around the clock for a long time, oil leakage will occur at the output shaft of the reduction box. On the one hand, the oil leakage pollutes the on-site environment, and on the other hand, it affects the normal operation of the reduction box. In the publication number CN213206517U, a device for recovering oil leakage from the reduction box of the oil pump is disclosed. The oil leaked from the reduction box is collected by an oil receiving box, and the oil in the oil receiving box can be filtered and continued to be used, which reduces the production cost. However, since the oil collecting box is open in design, on the one hand, dust can easily fall into the oil collecting box and mix with the oil; on the other hand, when it rains, rainwater can mix with the oil, making the collected oil unusable.
