Abstract
A hydraulic transmission device of pumping unit for improving working condition and saving energy is installed between speed reducer and motor of beam pumping unit, and is composed of casing assembled by front and back end covers, drive shaft, two sets of pump wheels, two sets of turbine, bearing, fusible plug, explosion-proof plug, connecting bolt and mechanical sealing element.
Description
Technical field
The utility model relates to a kind of device that the beam pumping unit transmission process improves the transmission working state that is used for.
Background technique
The load of pumping unit is the time varying load of unique characteristics: the branch that dynamic and static load characteristic is arranged.The starting torque of starting original state requirement dragging motor is 2-3 a times of pumping unit actual loading, and starting torque is the first element of pumping unit apolegamy motor.When the suitable then bearing power of starting torque must be mated not good, running load power is all much smaller than the rated power of motor, because will address the startup problem, motor capacity is selected greatlyyer, causes the motor phenomenon that power factor is low under the long-time running operating mode, operational efficiency is low in design.And pumping unit overall work situation is stable inadequately, and the impact that each component bore, vibration are bigger, and pumping unit is affected mechanical life.
Summary of the invention
The purpose of this utility model is to provide a kind of can reduce starting current, improve the pumping unit working condition, and the pumping unit dydraudynamic drive unit of overload protection can be provided.
The technological scheme that its technical problem that solves the utility model adopts is: adopt biliquid power Transmission Room structure, two chambers respectively are made up of one group of pump impeller, turbine, and transmission is realized by transmission fluid by two groups of pump impellers, turbines, can transmit bigger power.
The beneficial effects of the utility model are: can realize that pumping unit near zero load starting, will hang down starting current, alleviate impact electrical network, but and the rational Match power of motor, and can provide overload protection.

Embodiment
Front cover 1 and rear end cover 9 are formed the shell of a hollow dome body among Fig. 1, connect by attachment bolt 4.Driving shaft 15 is a hollow cylinder, is provided with the assembling step in its cylindrical place, by connecting rivet 16 turbine A2, pump impeller B6 and driving shaft 15 is coupled to one.Inner headed face one side is provided with the axle fixing bolt 14 that connects with motor shaft 22.Pump impeller A3, pump impeller B6 are the hollow wheel-shaped body, are uniformly distributed with 18-72 sheet blade on it along the circumference, and appearance profile matches with the front cover 1, the rear end cover 9 that serve as shell.The internal surface of front cover 1, rear end cover 8 is cast with and pump impeller similar number blade, forms turbine A2, turbine B8.
Behind the transmission oil of injection as the hydraudynamic drive working medium, can devote oneself to work by actuating motor in the device cavity from fusible plug 6 holes or to explosion-proof plug 16 holes before using.During work, the pump impeller A3 on the driving shaft 14 that motor drives links with it, pump impeller B6 rotation makes the transmission oil in the cavity produce kinetic energy, passes to turbine A2, turbine B8 and makes its rotation, drives drive wheel 18 rotations that link with it.Because the hysteresis of fluid power effect, the working condition in the time of can improving electric motor starting makes motor approach No Load Start.
This device is provided with fusible plug 7 and explosion-proof plug 16, and when the working medium temperature of device surpassed specified value, fusible plug 7 melted; When the working pressure of installing surpassed specified value, explosion-proof plug 16 was opened, and both of these case underdrive liquid can be discharged automatically, made motor dally, thereby realized the protection of motor and pumping unit.
Claims (5)
