Problems solved by technology

Regardless of the type of actuator, when the actuator fails and cannot be repaired immediately, it will stop the operation of the driven device and other parts connected to the actuator because it needs to be replaced with a new actuator , which in turn causes the shutdown of the process or production line that applies the entire actuator system, which is not economical

Abstract

The invention discloses an actuator with a failure self-prediction function. The actuator has a sensor assembly and a controller electrically connected to each other. The sensor assembly is used for outputting a time-dependent sensing signal which is related to an operation parameter of the actuator and changes along with time change in the operation process of the actuator. The controller is provided with a storage unit, a calculation unit and a notification unit. The calculation unit is used for calculating operation parameter trend lines corresponding to the time-dependent sensing signals of the last plurality of operation parameters stored in the storage unit and an accumulated time critical value of the actuator corresponding to the intersection point of the critical value of the operation parameters and the operation parameter trend lines. The notification unit is used for outputting the cumulative time critical value to a remote control center of the actuator.

Description

technical field [0001] The present application belongs to the field of actuators, and in particular, relates to an actuator with a failure self-prediction function. Background technique [0002] Actuators include pneumatic actuators, hydraulic actuators and electric actuators, which are commonly used in valve motion control of fluid valves ( valve motion control). Pneumatic or hydraulic actuators use the pressure of compressed gas or liquid to drive the movement of a specific mechanism to provide the linear or rotational motion required by the driven device, while electric actuators use electrical energy to convert into mechanical energy. The required motion of the driven device. No matter what type of actuator, when the actuator fails and cannot be repaired immediately, it will stop the operation of the driven device and other parts connected to the actuator because it needs to be replaced with a new one. , thereby causing the shutdown of the process or production line a...
