Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a split-type multi-rotation electric actuator. Background Art

[0002] The split multi-turn electric actuator is a uniquely designed electric actuator. Unlike the one-way stroke actuator, the multi-turn actuator can realize multiple rotation directions or angles. This function makes it suitable for occasions that require complex movements or multi-angle control, such as valve control systems that need to frequently adjust the direction or angle. This actuator is usually controlled by an electric drive system and realizes rotation by inputting electrical signals or other control signals. Electric control makes it high-precision and high-reliability, and it can be integrated with the automation system to achieve remote monitoring and control.

[0003] The current split-type multi-turn electric actuator generally has the controller and the actuator body completely separated and connected. There is no connection structure between the controller and the actuator body, which makes the equipment only usable as a split type, which has certain limitations. When the actuator body needs to be inspected, the multiple bolts on the end cover need to be removed, which is not only time-consuming and labor-intensive, but also has low portability.
