Detailed description of the invention
As it is shown in figure 1, a kind of integrated pumping unit load simulator of the present invention, including industrial computer and driving
Motor 1, driving the power output shaft of motor 1 to connect has a gear-box 6, and drive be provided with on the power output shaft of motor 1 with
The torque rotary speed sensor 5 that industrial computer signal connects, gear-box 6 connects magnetic powder brake 3 and magnetic powder cluth 4, magnetic
Powder clutch 4 connects negative load motor 2；Drive motor 1 to use the monopole asynchronous motor of band decelerator, and drive motor
Yielding coupling is used to couple between the power output shaft of 1 with magnetic powder brake 3 power shaft.
As in figure 2 it is shown, industrial computer connects analog output module and Analog input mModule, analog output mould
Two analog output channels of block are connected to a programmable power supply, two programmable power supplys respectively with magnetic powder brake 3 and
Magnetic powder cluth 4 connects；Two analog input channels of Analog input mModule are connected to a power transducer, and two
Individual power transducer is connected with driving motor 1 and negative load motor 2 respectively.Analog output module selects ADAM-4024 type
Number, described Analog input mModule selects ADAM-4017 model.Industrial computer is provided with RS232 or RS485 serial line interface,
And industrial computer connects operation control panel.Operation control panel is that operator provide visualization operation.
The operation principle of power transducer is to utilize mutual inductance principle tested electric current and ac voltage signal to be gathered simultaneously,
Calculate according to parameters such as phase places, be ultimately converted to the d. c. voltage signal linearly exported with active power.Simulation input
Amount module selection ADAM-4017, ADAM-4017 are the Analog input mModule of 16 A/D8 passages, can gather current/voltage
Analog input signal, its 3000V voltage that provides between analog input channel and module is isolated, and effectively prevents module
Damaged when by impacting with high pressure.When computer sends request command, module can pass to calculate by RS-485 interface
Machine.
Continuous control includes loading and the frequency of electromotor drive motor of magnetic powder brake 3 remote control voltage.Magnetic powders brake
The loading of the remote control voltage of device 3 is divided into manual loading and automatically loads two ways, and manual loading is mainly in the debugging of test
In the stage, manually load test magnetic powder brake 3 operation conditions.Automatically loading mainly includes each yeast inoculation wanting load operating
Line.Imitated output quantity module selects ADAM-4024, ADAM-4024 to be 4 analog output channels, tunnel.Current/voltage can be exported
Analog signals, the voltage signal of output 0-10V.
Every the voltage signal of the ADAM-4024 output 0-10V that 1s is connected by RS485, programmable power supply produces 0-1A's
Exciting current signal.Magnetic powder brake 3 produces braking torque under the control of exciting current, and in the cycle completing load, segmentation adds
Carry.In order to verify the stability of complementary power supply system under periodic loading, and the running status of driving load motor, examination
In testing, operation power to motor carries out on-line checking, and monitors the output of motor in real time by torque rotary speed sensor 5 and turn
Speed and torque.The starting current of motor is beyond the current range of transmitter, therefore selection type current transformer, Jing Guo electricity in test

Input is to industrial computer.
Its operation principle is: drive motor 1 to be equivalent to the motor of oil pumper, and negative load motor 2 is mainly used to simulate undershoot
Negative load during journey.When simulating positive load change, magnetic powder cluth 4 does not works, and magnetic powder brake 3 is used for loading positive load
Analog parameter.Fictitious load lotus change time, magnetic powder brake 3 does not works, and magnetic powder cluth 4 is connected with gear-box 6, magnetic powder from
The negative load analog parameter that clutch 4 loads passes to drive the output shaft of motor 1 by gear-box 6, completes negative load and loaded
Journey.
When magnetic powder brake 3 works, when exciting curent is when there being electric current to pass through, yoke produces operating magnetic field flux, work
Magnetic powder in chamber is that chain couples together formation magnetic powder chain along flow direction, and magnetic powder brake 3 is by now magnetic powder and magnetic powder, magnetic powder
And the shearing force between frictional force and magnetic powder chain between work surface transmits torque, magnetic powder brake 3 is in on-position, disconnected
Open the electric current in magnetizing coil, the magnetic powder in working chamber under gravity in loose condition (of surface), and produced by power shaft from
Under mental power function, magnetic powder is got rid of uniformly on the inwall of power rotor, interaction unable between power shaft and fixing end,
Magnetic powder brake 3 is in released state, does not has the transmission of torque.For magnetic powder brake 3 provide exciting curent for matching
Programmable power supply.It has simple in construction, it is easy to control, and has RS232 (or formulate RS485) serial line interface, can with computer,
PLC communication connects, and working method has hand controlled, remote controlled, communication and manual 3 kinds.
The above is only the preferred implementation of this patent, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from the art of this patent principle, it is also possible to make some improvement and replacement, these improve and replace
Also should be regarded as the protection domain of this patent.
