Electric actuator detection device and detection method thereof

Abstract

The invention discloses a detection device for an electric actuator, which is used for measuring the torque and rotational speed of the electric actuator, comprising a transmission system, a torque feedback system, a rotational speed feedback system and an air path control system; the output end of the transmission system is a friction loading mechanism Driven, a circumferentially floating annular support plate suspended horizontally in the main bracket; the annular support plate floats circumferentially in the main bracket through a number of floating load-bearing mechanisms distributed around it, and the transmission system is driven by the floating load-bearing mechanism The gravity is transmitted to the main bracket; the floating load-bearing mechanism is fixed around the main bracket; the floating load-bearing mechanism is provided with a support frame, and relative to the annular support plate, a lower sliding assembly, an upper sliding assembly and a peripheral sliding assembly are provided. components. The invention has the advantages of simple structure, flexible installation, long service life, easy maintenance, and can reach a test capability of 10,000 N.M torque; it meets the test requirements for electric actuators and improves user experience.

Description

technical field [0001] The invention relates to the technical field of industrial automation control, in particular to an electric actuator detection device and a detection method thereof. Background technique [0002] The electric actuator is an industrial product that drives the valve by the torque at the output end to control the flow of the medium. The electric actuator detection device is the key equipment used to detect and check the torque capacity of the electric actuator. It is simulated by the brake system. Field loads to implement the testing process. The measurement range of the current electric actuator detection devices is within 2000N.M, basically there is no test capability of 10000N.M large torque, and at the same time, the cost of the integrated torque sensor is relatively high. [0003] In order to ensure the reliability of the electric actuator, a low-cost electric actuator detection device with a test capacity of 10000 N.M torque is needed at present. ...
