Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with accompanying drawing, the present invention is entered
Row is further described.
As illustrated, the invention provides a kind of torsional oscillation testing experiment stand with overload protection function, including：
It is connected to the power intake electromotor 1 and outfan motor at test rotary device 3 two ends by shaft coupling respectively
5, test rotary device 3 two ends are also separately installed with two torque rotary speed sensors 2,4, to monitoring test rotary device
The real-time torque of 3 inputs and outfan and rotating speed；Outfan motor 5 is load motor；
To testing the oil pressure pumping plant 12 that rotary device 3 is lubricated；
To the two data display instruments 7,8 for showing the torque rotary speed signal of two torque rotary speed sensors 2,4 respectively；
To the electric cabinet 6 for adjusting the torque rotary speed of outfan motor 5；
Adjust to collect the torque rotary speed signal of two torque rotary speed sensors 2,4 and control electric cabinet 6 according to the signal
The torque of outfan motor 5, the control box 9 of rotating speed.
By wire A31 short circuits, two turn the two rotating speed upper limit+connection jaws 19 in described two data display instrument 2,4
The fast upper limit-connection jaws 20 are connected by wire B32 short circuits and with the control box signal reception connection jaws 29 in control box 9, with this
By the signal input of torque rotary speed to control box 9.Load motor scram button 34 is provided with the control box 9, to defeated
Go out to hold the jerk of motor 5 to control.Motor output torque control knob 27 is provided with the control box 9, to outfan electricity
The moment of torsion of machine 5 is adjusted.Also include the power supply A10 being connected with two data display instruments 7,8, to two data display instruments
7th, 8 the energy is provided.Also include the power supply B11 being connected with oil pressure pumping plant 12 and electric cabinet 6 respectively, to oil pressure pumping plant 12 and electric cabinet
6 provide the energy.Electric cabinet 6 is connected with the attached resistance 13 of electric cabinet and resistor box 14.Control box 9 is connected by wire C33 with electric cabinet 6.
Specifically, as illustrated, two torque rotary speed sensors 2,4 are separately mounted to test the two ends of rotary device 3, to
The real-time torque of the input of monitoring test rotary device 3 and outfan and rotating speed.Test rotation in the 12 pairs of tests of oil pressure pumping plant
Device 3 is lubricated.Data display instrument 7,8 is used for showing the signal of torque and rotating speed, two rotating speeds in data display instrument 7,8
The upper limit+connection jaws 19 by wire A31 short circuits, the two rotating speed upper limit-connection jaws 20 by wire B32 short circuits and with control box 9
In control box signal receive connection jaws 29 connect, with this by the signal input of torque rotary speed to control box 9.The basis of control box 9
The torque rotary speed signal collected is controlled control signal to load motor by electric cabinet 6.
