Detailed description of the invention
With reference to Fig. 1, a kind of fluid drives oil pumper, and the support assembly 1 comprising base assembly 25 and it connects, connects inclined support bar 18 therebetween; The top mounting rotary drum bearing 10 of support assembly, which is provided with cylinder 9, and cylinder 9 upper surface is wound with belt 5, drum shaft is provided with speed detector 11, and cylinder 9 also installs brake gear, and brake gear comprises brake 8 and brake drive unit 12; The upper and lower of support assembly 1 is fixed with upper and lower part fluid tank 14,20 respectively, and connected by the fluid lifts system 22 be arranged on base assembly 25, fluid lifts system 22 comprises pump (being driven by motor 23) and liquid carrying riser 17, the bottom of upper flow case 14 is provided with liquid conduits 16, and it installs electromagnetic valve; Support assembly 1 is provided with up and down righting guide rail, and it is installed the fluid driving box 19 that can move up and down along guide rail, fluid driving box 19 bottom is provided with bottom opening device 3, and it installs control valve; The upper and lower part of support assembly 1 is provided with lead limit switch 2 respectively, moves back and forth overshoot journey for preventing oil pumper; After cylinder 9 walked around by belt 5, one end is connected with polished rod eye 6, and the other end is connected with fluid driving box 19.Fluid driving box 19 is also provided with tandem-driving bogie fixed weight 4, and the two connects as one.Whole device is controlled by the electric control cabinet 24 on base assembly, is previously provided with control program, obtains Automated condtrol in the phase.
During use, oil pumper is not when installation and fluid lifts system start on request, and fluid driving box is positioned at the top of stroke under rod string Action of Gravity Field, and whole fluid is arranged in lower flow case.Start fluid lifts system works, fluid is successively risen to upper flow case, the electromagnetic valve controlling top is opened, fluid is by liquid conduits incoming fluid driving box, when in fluid driving box and balance weight assembly and case, the weight of fluid is greater than weight and the rod string resistance of motion of rod string, fluid driving box is descending together with balance weight assembly, after speed detector detection cylinder velocity of rotation reaches established standards, closes upper flow case electromagnetic valve.When fluid driving box and balance weight assembly are close to bottom of travel, bottom opening device opens drive fluid case electromagnetic valve, fluid flow in lower flow case, when the weight that the weight of fluid in fluid driving box and balance weight assembly and case is less than rod string is to certain value, fluid driving box and balance weight assembly start up, close the electromagnetic valve on fluid driving box simultaneously, and start fluid lifts system, by the fluid lifts in lower flow case in the fluid tank of top.When fluid driving box and balance weight assembly are close to top of stroke, the electromagnetic valve controlling upper flow case is opened, fluid by liquid conduits by incoming fluid driving box in upper flow case, when in fluid driving box and balance weight assembly and case, the weight of fluid is greater than weight and the rod string resistance of motion of rod string, fluid driving box is descending together with balance weight assembly.So, fluid lifts system constantly by the fluid lifts in lower flow case in upper flow case, fluid control systems controls fluid and flows out upper flow case, inflow and effluent fluid driving box by the program designed, along with increase and the minimizing of Fluid Volume in fluid driving box, achieve the descending and up of fluid driving box and balance weight assembly, realize pumping of rod string to the greatest extent and by its driving belt assembly connected, realize oil pumper continuous operation.Security protection system realize rod string disconnected de-time, speed detector exceedes setting speed, and brake gear works, and the fluid tank in protection frame is fallen, and protection safety of pumping unit, prevents mechanical accident.
