Abstract
The invention discloses a system for measuring response time of an electromagnet. The system comprises a valve block fixture, the electromagnet and a power module; the electromagnet is arranged on the valve block fixture; the power module is connected with the electromagnet which comprises a movable armature; the system further comprises an induction module which is arranged on the valve block fixture; movement of the movable armature inside the electromagnet can be detected though the induction module and then the response time of the electromagnet can be measured out. The system for measuring the response time of the electromagnet is convenient to operate and low in cost.
Description
Technical field
The present invention relates to a kind of electromagnet reaction time measuring system, especially a kind of electromagnet reaction time measuring system based on acceleration transducer.
Background technology
The electromagnet reaction time refers to electromagnet when power on/off, and needed time when inner armature arrives assigned address or reposition, it is an important parameter of work of electromagnet.In the hydraulic control circuit design, be directly connected to control accuracy and response speed.The measurement in existing reaction time is normally based on infrared distance sensor; Have higher requirements but based on the reaction time measuring system of infrared distance sensor, signal is processed, need to drop into more cost.
Therefore, be badly in need of a kind of new measuring system of design.

Embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, a kind of electromagnet reaction time measuring system, comprise valve piece tool 1, be installed on the electromagnet 6 of valve piece tool 1 and be connected in the power module 4 of electromagnet 6, this electromagnet 6 comprises movably armature 9, and wherein said electromagnet reaction time measuring system further comprises the induction module 2 that is installed on valve piece tool 1.Induction module 2 is for detection of the course of action of the armature 9 of electromagnet 6, and in the present invention, described induction module 2 is acceleration transducer.What described power module 4 adopted is the 24V direct supply.Described electromagnet reaction time measuring system further comprises the signal generator 7 that connects induction module 2 and the display module 3 that is connected with signal generator 7 other ends.Described display module 3 is voltage display module, is specially oscillograph in the present invention.Described valve piece tool 1 is solenoid valve.Described power module 4 comprises positive interface 41 and negative interface 42, is connected with resistance 5 between positive interface 41 and electromagnet 6, is used for measuring the electric current of this circuit.Positive interface 41 and 42 voltage U 1 of negative interface of power module 4 are connected to display module CH1 passage, and resistance 5 both end voltage U2 are connected to display module CH2 passage.Signal generator 7 converts the signal of induction module 2 of access to voltage signal U3 and is connected on display module CH3 passage.Signal generator 7 connects second source module 8, is specially the 220V AC power.
Can produce following sync waveform on display module, 42 voltage signal U1 of the positive interface 41 of power module 4 and negative interface, the voltage signal U3 that the voltage signal U2 on resistance 5, the signal of induction module 2 produce after processing through signal generator 7.After energising, armature 9 under the effect of electromagnetic field to the position movement of appointment, induction module 2 detects this motion, the output signal that is induction module 2 is corresponding with the motion of armature 9, and the voltage signal U3 of signal generator output also changes immediately, because acceleration in armature 9 motion processes is constantly to change, acceleration transducer detects this variation, voltage signal U3 is the value that constantly changes, and moves to after assigned address stops at armature 9, and voltage signal U3 returns to stable value.Be that voltage conduction time to armature motion puts in place by observing the variation of voltage signal U3, testing out the electromagnet reaction time.
The above is only the preferred embodiment of the present invention, should be pointed out that for the ordinary skill in the art, not breaking away under principle prerequisite of the present invention, can also make various deformation and improvement, and this also should be considered as protection scope of the present invention.
