At present, the majority of oil production plants use tubular pumps for exploitation, the depth of the pump under the pump is affected, the general depth of the underground pump is shallow, at 1400 ~ 1800m or so. For deep wells, the tube pump "out of the reach." In July 2005, the oil extraction plant introduced the rod pump efficient lifting supporting technology, using small diameter series oil pump continuous lifting, small pump deep pumping, pump depth up to 2200 ~ 2300m. The test was carried out in No.4 Mine LJL52-10 well and put into production on August 7, with good results. Re-testing is currently underway in LJL 52-12.
Driving & Driven Cylindrical Gear
Gear mechanism is used to transfer motion and power between two shafts,and is the most widely used transmission mechanism,It is through the meshing of gear teeth to achieve the transmission requirements,so compared with the friction wheel,pulley and other mechanical transmission,its remarkable characteristics are:stable transmission ratio,reliable work,high effciency,long life,suitable for a wide range of diameter,circumference speed and power.
Cylindrical gear is an important gear type in mechanical gear,but also the most common gear style.
Cylindrical gears accroding to the direction of the teeth,can be divided intospur cylindrical gears,helical
Cylindrical gears and herringbone cylindrical gears
