Performance detection system and detection method for rotary valve actuator

Abstract

The invention discloses a performance detection system and detection method of a rotary valve actuator, the detection system comprises a computer system, a control system, a data acquisition system, a tool clamp system and a driving system, and the stroke driving test, the position breakthrough test and the locked-rotor torque test of the valve actuator are realized. The method provided by the invention solves the problem that various different test systems need to be provided when various types of rotary valve actuators are subjected to performance tests at present, and is more universal; and furthermore, the performance detection problem of the actuator under the condition of working state change under different actual working conditions is solved. When the actuator works in the forward and reverse directions, the testing system provides a same-direction driving torque for the actuator and detects the working performance of the actuator; or the testing system provides different-direction driving torque to detect the working performance of the actuator.

Description

technical field [0001] The invention belongs to the technical field of valve detection, and in particular relates to a performance detection system and a detection method of a rotary valve actuator. Background technique [0002] Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. Electric actuators can be used to control valves of all sizes. The actuator has intelligent torque control, which can perform stall protection for the motor, while maintaining low-power operation in the standby state, and is the core component of the valve. At present, the performance testing of various valve actuators is a single type of valve testing method, which does not have universality and integrity. The existing technologies are mostly single-function detection of the actuator, such as stroke detection, position...

Problems solved by technology

At present, in the performance testing of various valve actuators, there is a single type of valve testing method, which does not have versatility and integrity

Most of the existing technologies are single-function detection of the actuator, such as stroke detection, position control, etc., whether the change of the working state of the actuator caused by the torque change, angle change and electrical parameter change in the actual working condition of the actuator is satisfied. Performance index requirements, cannot be effectively verified
