Abstract

The invention belongs to the technical field of pumping units, in particular to an automatic cleaning device for oil well polished rods, aiming at the inconvenient cleaning of the existing oil well polished rods due to the inconvenient cleaning of the suspended matter and impurities carried during use, resulting in a low service life of the polished rods and easy cleaning of the polished rods. As a result of the problem of poor sealing, the following scheme is now proposed, which includes a base, the top of the base is fixedly installed with a fixed seat, the fixed seat is movably connected with the polished rod body, and the outer fixed sleeve of the fixed seat is provided with a fixed plate to fix the There are four water guide chambers and four conversion chambers on the board, a cleaning chamber is provided on the fixed seat, and eight through holes are opened on the inner wall of the cleaning chamber, and the through holes are connected with the corresponding water guide chambers and conversion chambers In general, a cleaning mechanism is provided on the inner wall of the cleaning chamber. The invention is simple in operation and convenient in use, and can facilitate scraping and flushing of polished rods, and at the same time, can also recycle water sources and carry out filtering and exporting, which is convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of pumping units, in particular to an automatic cleaning device for oil well polished rods. Background technique [0002] The polished rod of the pumping well is at the uppermost part of the sucker rod, which bears the greatest force and has a smooth surface. It is combined with the packing in the packing box to seal the wellhead, prevent oil, gas, and water from leaking, and realize the connection between the sucker rod and the rope hanger. overconnection. In some oil wells, the viscosity of the produced fluid increases, and the ability to carry suspended solids increases, causing serious wear and corrosion, and aggravating bacterial reproduction, which makes bacterial corrosion worse. There is a problem of severe corrosion of polished rods. Large potholes appear in polished rods, resulting in poor sealing of the packing and leakage. Seriously oily. [0003] The existing oil well polished rods are inconve...
