Abstract

The invention discloses an electric actuator detection device which comprises a transmission system, a brake system, a gas channel control system and a feedback system. The outer portion of the electric actuator detection device is connected with an electric actuator. The input end of the transmission system is provided with an input shaft of a brake pad of a friction loading mechanism and coaxially connected with a transmission shaft of the electric actuator. The output end of the transmission system is provided with an annular support plate driven by the friction loading mechanism, horizontally hung in a main support and capable of floating in the circumferential direction. The annular support plate floats circumferentially in the main support through a plurality of floating weight bearing mechanisms distributed around the annular support plate, and the gravity of the transmission system is transferred to the main support through the floating weight bearing mechanisms. The feedback system comprises a tension sensor and universal joints. The tension sensor is connected with a first universal joint and a second universal joint, the first universal joint is arranged on the main support, and the second universal joint is arranged on the annular support plate. The electric actuator detection device is simple in structure, compact in size, flexible to install, long in service life and easy to maintain, simplifies an installation process, enables gas channel sealing to be reliable and modularized, and can achieve batch production.

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. ...
