Abstract

An oil pumping unit soft start coupler comprises an output shaft, a shell body, an input shaft, a centrifugal block, a coupling drum wheel, a drive wheel, a motor, a bearing and a connection disc, wherein the input shaft is fixedly connected with the drive wheel, the input shaft is provided an inner hole and a key groove, the drive wheel is provided with a side plate, the side plate shifts the centrifugal block to rotate, the centrifugal block is composed of four quarter circular rings, friction plates are attached to the external round face of the centrifugal block, when the coupling drum wheel achieves a certain rotating speed, the centrifugal block leans towards the coupling drum wheel under the action of centrifugal force and rubs against the coupling drum wheel to transmit torsion, the coupling drum wheel is fixedly connected with the output shaft, two ends of the coupling drum wheel and two ends of the output shaft are provided with rolling bearings, and the connection disc is arranged at the right end of the shell body. The oil pumping unit soft start coupler adopts mechanical friction separation and reunion, is simple in structure, achieves no-load starting of the motor, is small in starting current, lowers installed power, achieves soft start of an oil pumping unit, protects oil-pumping equipment, saves electricity energy, and improves mechanical transmission efficiency.

Description

Pumping unit soft start Coupler
Technical field
The utility model relates to oil-field oil pumper dynamic power machine transmission soft start coupling technique, specifically a kind of pumping unit soft start Coupler.
Background technique
Pumping unit all is that band carries startup when starting, it is larger to start load, the oil field is smooth in order to start when the apolegamy motor, do not affect production, general by maximum starting torque apolegamy motor, and pumping unit start after during normal operation average torque compare lowlyer with Maximum Torque, so power input to machine generally only has 1/3rd of rated power, this is the main cause that causes " low load with strong power ".Secondly, the oil field considers that oil well condition is unusual when the apolegamy motor, during such as sand card wax deposition, the reason difficulty in starting does not burn motor, frequent motor not when oil well load becomes large because of the reasons such as well workover load, and artificially increased the power of motor capacity, aggravate " low load with strong power " this phenomenon.Use the pumping unit soft starting device of some different principle and structure in the past, also produced some useful effects, but also in various degree some problems of existence.Adopt SCR control device soft start, played certain effect, but this scheme exist electric complicated, reliability reduces, the not enough problem of detent torque.Adopt pumping unit hydraulic couplers transmission system, can realize the soft start of pumping unit, but because hydraulic couplers is take liquid as medium, by the variation transferring energy of the liquid moment of momentum, so there is energy loss in hydraulic couplers itself, and mechanical efficiency is less than 1.Attached with frequency converters can reach preferably soft start effect by the electric properties that change actuator, and electric complexity, reliability reduce, the not enough problem of detent torque but this scheme also exists.Adopt double speed or multispeed electric machine to substitute the soft start scheme of common threephase asynchronous, can transfer ginseng, change swabbing parameter motor, but shortcoming be the motor low speed start that corresponding moment of torsion is difficult to improve, so the soft start DeGrain.Employing is installed accumulator flywheel and clutch device at motor output shaft, can realize the soft start of pumping unit, but needs Flywheel, and structure is complicated.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of pumping unit soft start Coupler is provided.
The utility model comprises: output shaft, housing, input shaft, centrifugal-block, coupling drum, driving wheel, motor, bearing, tie-plate.Input shaft and the driving wheel of its pumping unit soft start Coupler are fixedly connected, input shaft is provided with endoporus and has keyway, connect with motor shaft, driving wheel is provided with side plate, side plate is stirred the centrifugal-block rotation, centrifugal-block is that four quadrant rings form, post friction plate on its periphery, centrifugal-block relied on the coupling drum when driving wheel reached certain rotating speed under the effect of centrifugal force, with coupling drum generation overall viewing range, coupling drum and output shaft are fixedly connected, when the input shaft rotating speed reaches certain value, the friction torque of centrifugal-block is when starting load, and the coupling drum namely can drive the output shaft rotation.During normal operation, the moment of torsion that the centrifugal-block maximum static friction force produces is greater than Operating torque, so do not slide between centrifugal-block and the coupling drum, and input shaft equates with the output shaft rotating speed, can guarantee higher mechanical efficiency.Coupling drum and output shaft two ends are provided with rolling bearing, and the housing right-hand member is provided with tie-plate, and land connects with motor housing.
The beneficial effects of the utility model are: adopt the mechanical type friction clutch, and simple in structure, realize that empty load of motor starts, inrush current is little, the pumping unit soft start, the protection pumping unit, saving power improves machinery driving efficiency.
