An automatic tightening device for pumping unit packing with remote monitoring function

Abstract

The invention discloses an automatic screwing device of an oil pumping machine packing and with a remote monitoring function and belongs to the technical field of mechanical equipment. The automatic screwing device comprises a polished rod, an upper gland, two screwing nuts, the packing, a driven gear, a baseplate, a shell, a force sensor, a motor, a torquer, a remote measuring and controlling terminal, a mobile communication module, a network communication module and a driving gear, the screwing nuts are arranged on two sides of the polished rod respectively, both the upper gland and the packing are arranged below the screwing nuts, the motor is connected with the torquer, the force sensor is arranged at a shaft neck of the driving gear, the output end of the force sensor is connected with the remote measuring and controlling terminal, the output end of the remote measuring and controlling terminal is connected with the motor, and the mobile communication module and the network communication module are connected with the remote measuring and controlling terminal. The automatic screwing device can realize automatic detection and on-site or remote control and can screw the packing, so that manpower well inspection expenditure is saved, working efficiency and safety are improved, oil leakage is avoided, and energy resources are saved.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to a wellhead device for automatically tightening packing. Background technique [0002] Mechanical oil extraction is the main way to exploit crude oil in major oilfields in my country. Among them, the rod pumping equipment composed of pumping unit, pump and sucker rod occupies a dominant position in mechanical oil recovery, and the packing box polished rod sealer is a Polished rod sealing device is indispensable in rod production equipment. [0003] At present, known wellhead device is made up of casing head, tubing head, oil pumping tee pumping unit, oil well pump, sucker rod, packing box polished rod sealer. It is the key equipment for suspending downhole tubing string and casing string, sealing the annular space between oil casing and two-layer casing, reinjection and safe production. The sealing device is generally installed on the small spool of the wellhead devi...

Problems solved by technology

Due to the huge distribution range and quantity of pumping units, well inspection is very heavy. For oil wells in some harsh environments, such as deserts, Gobi, swamps, etc., special machinery is required to enter these areas, which not only increases the labor of inspection wells The labor intensity also greatly increases the cost of well patrolling. At the same time, due to the danger of these environments, well patrolling personnel are always facing the threat of life
