TOWER-STYLE DOUBLE CYLINDER HYDRAULIC OIL PUMPING UNIT

' Tower-style Double Cylinder Hydraulic Oil Pumping Unit' ('the Unit') is an integrated electromechanical product developed for viscous oil well production needs, which adopts hydraulic technique to provide efficiency and reduce energy consumption. The Unit is composed of a Frame section ('tower') and a hydraulic pumping system. The Frame section includes: a Main frame; two oil Cylinders (A and B, see (17) and (18) in Graphic 2 for details), each of which includes a Tank ((2) in Graphic 1, same with below) and a Piston Rod (4); movable pulley group; Oxbow (Beam Hanger); counterweight fixed pulley groups; rim fixed pulley groups; top fixed pulley groups; lid; Sucker Rod pulling rope (steel wire); counterweight pulling ropes(steel wire); two triangular frames; counterweight steel wire ropes; fixed supporting frame; pulley fixer frame; counterweight; and mobile supporting-guiding frames and rails which move with the movable pulley groups. The Unit features two oil Cylinders in turn make telescopic movements, downward when stretching out (oil comes in) and upward when retracting (oil pumped out). A driving oil pump with electronic motor constantly pumps out high pressure hydraulic oil that drives the movements of the Cylinders. One Cylinder drives the Sucker Rod to make the upstroke and another drives the counterweight to make the down stroke. By adjusting the counterweight to make the loads of 2 Cylinders equal, the electronic motor operates with constant load and in single direction, therefore the Unit could realize high efficiency, save a significant part of power consumption, while also have a lighter, simpler structure than existing oil pumping units.

TOWER-STYLE DOUBLE CYLINDER HYDRAULIC OIL PUMPING UNIT

A tower-style double cylinder hydraulic pumping unit has a first cylinder and a second cylinder.

The cleaning structure is used for cleaning the marine life on the sealing surface of the gate when the cleaning structure moves to the corresponding position on the sealing surface of the gate. The rigging structure (3) is connected to the lifting device, so that when the cleaning device is moved to the corresponding position on the sealing surface of the gate by means of the lifting device, the cleaning structure can clean marine life. Not only are the problems of the efficiency of the cleaning manner of a diver being low and potential personal safety hazards avoided, but the problem of the movement stability of magnetic adsorption being poor is also obsolete.
