Abstract
The invention discloses static characteristic test equipment for a proportional electromagnet. The equipment comprises a servo motor, a ball screw, a displacement sensor, a force sensor, a control panel and a computer. The proportional electromagnet is placed on a testing fixed platform, the ball screw is driven by the servo motor to keep contact with an armature on the proportional electromagnet all the time, the displacement sensor is used for collecting the axial displacement value of the ball screw and inputting the value to the computer, the electromagnetic force generated by the proportional electromagnet is input to the computer through the force sensor, the control panel can be used for controlling the correctness of data input into the computer, and after the processing of the computer, the curve graph of force and displacement relationship is automatically displayed on a display device.
Description
Technical field
The proportion electro-magnet static characteristic testing apparatus that is used for proportion magnetic valve.
Background technology
Proportion magnetic valve is widely used in the automatic control loop in various fields as the electromechanical conversion element of electric-hydraulic proportion control element, and its function is that electricity is converted to power or displacement output.Because its control accuracy height, contamination resistance is strong, and functions such as guide's control load and pressure compensation have the trend that replaces servo-valve.Proportion magnetic valve adopts PWM(pulse-length modulation Pulse Width Modulation, also claims the dutycycle control technology) control, and its drive part proportion electro-magnet characteristic and solenoid valve mate, and directly influence the performance of solenoid valve.In the static characteristics of proportion electro-magnet, under the certain situation of input current, the external acting force location independent residing of moving component in the solenoid valve with it, the displacement-force curve that is level concerns.The theoretical research of present domestic Comparative Examples electromagnet performance test is more deep, but generally all is to be undertaken by other equipment for Performance Detection, does not have the checkout equipment of specialty.
Summary of the invention
The object of the present invention is to provide a kind of static characteristic testing apparatus that is used for proportion magnetic valve, just can obtain accurate experimental data on stream, have very strong specific aim.
Above-mentioned purpose is achieved through the following technical solutions:
Proportion electro-magnet static characteristic testing apparatus, it is characterized in that: include servomotor, ball screw, displacement transducer, force transducer, control panel and computing machine, proportion electro-magnet is positioned on the test fixed station, ball screw is remained by driven by servomotor and armature on the proportion electro-magnet and contacts, the axial displacement value that displacement transducer is gathered ball screw inputs to computing machine again, the electromagnetic force that proportion electro-magnet produces is imported computing machine by force transducer, control panel can be controlled the data correctness in the input computing machine, after the Computer Processing power and displacement relation curve map is presented on the display automatically.
Advantage of the present invention: have total digitalization and show, good man computer interface improves measuring accuracy and testing efficiency, just can obtain accurate experimental data on stream and can store consulting.
The present invention can also be in order to compression spring and the power of flat spring and the curve of displacement of test solenoid valve except the static characteristic that can test proportion electro-magnet.
Description of drawings
Fig. 1 is a fundamental diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, proportion electro-magnet static characteristic testing apparatus, this operation of equipment: first Comparative Examples electromagnet 5 preheatings 15 minutes, leave 0 for preventing armature, guarantee by servomotor 1 follow-up characteristic.Ball screw 2 is remained with armature by servomotor 1 driving and contacts.The different dutycycle precision of each input will lean on the high precision of servomotor corner to guarantee.The axial displacement value of ball screw 2 is gathered input computing machine 7 by displacement transducer 3.The electromagnetic force that proportion electro-magnet produces is imported computing machine 7 by force transducer 4 by amplifier.By Computer Processing, power and displacement relation curve are presented on the display of computing machine 7 automatically.Different dutycycles can be imported continuously, the parallel curves of many power and displacement can be shown at display.PWM control panel 6 guarantees that computing machine input data are accurate.
