Technical field
The utility model relates to the technical field of electric device for valve motor being carried out to the comprehensive detection such as nominal torque, stall moment of torsion, electric current, rotating speed and noise, especially relates to a kind of electric device for valve motor experimental bench.
Background technology
To produce and in design process, the parameters of motor is mostly theory speculates, and partial parameters is provided by motor producer at electric device for valve in the past, lack instrument detection, therefore, cannot the actual performance parameter of accurate perception motor.When valve design valve electric device, because the parameter of electric machine grasps out of true, especially the detent torque of motor, no-load torque and locked-rotor torque, likely cause selected power of motor improper.If motor real power is excessive, then waste can be caused; If motor real power is too small, then electric device for valve Driving Torque can be caused inadequate, be unfavorable for design and the production of electric device for valve.Only according to the motor rated power that motor producer provides, the transmission efficiency calculating electric device for valve adds difficulty.Detect comparatively comprehensively performance parameter by this test unit, comparatively accurate transmission efficiency can be calculated.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome in prior art produce electric device for valve time, parameters due to motor is mostly theory speculates, each data parameters accuracy is not high, cannot the actual performance parameter of accurate perception motor, be unfavorable for the design of electric device for valve and the problem of production, now provide a kind of electric device for valve motor experimental bench, it accurately can detect every actual performance parameter of motor.
The utility model solves the technical scheme that its technical matters adopts: a kind of electric device for valve motor experimental bench, comprise electric machine joint, joint flange, torque sensor and base, base is installed the first support and the second support, one end of electric machine joint and transmission shaft is in transmission connection, the other end of transmission shaft and one end of torque sensor are in transmission connection, the other end of torque sensor is connected with magnetic powder brake, torque sensor is arranged on the first support, joint flange is fixedly installed on the second support, the axis of joint flange and the dead in line of transmission shaft.
Further, coupling shaft, drive sleeve and secondary coupling shaft are also installed between torque sensor and magnetic powder brake, described torque sensor and coupling shaft are in transmission connection, and described magnetic powder brake is in transmission connection with time coupling shaft, is in transmission connection between described coupling shaft and secondary coupling shaft by drive sleeve.By regulating the loading current of magnetic powder brake, form the braking gradually to magnetic powder brake axle, the rotating speed of brake shaft declines gradually.Now, there is speed discrepancy in the transmission shaft at torque sensor two ends, and then force torque-transmitter shaft to produce distortion, the output torque of motor finally detected by torque sensor.Because magnetic powder brake loading current is adjustable, so the output torque of motor under different loads state can be detected.
Further, also have the knotmeter for detecting motor speed, described knotmeter is arranged on drive sleeve side.
Further, also having can the noise level monitor of detection noise, and noise level monitor is arranged on base, and is positioned at by motor, the noise produced when can detect motor rotation.
Preferably, knotmeter is stroboscope.
The beneficial effects of the utility model are: the utility model can detect the actual performance parameter of motor, by the motor test data grasped, can improve and optimize electric device for valve in the flow process designed and produce, improve the quality of product and reduce costs.
