Product Introduction
The SE series electric actuators are developed by Tianjin Baoheng Fluid Control Equipment Co., Ltd. based on the absorption of advanced technologies from mainstream electric actuators both domestically and internationally, combined with domestic market demands and the current development direction of international mainstream electric actuators. This product has independent intellectual property rights, is suitable for various industries, and can meet the requirements of explosion-proof occasions. Its performance indicators, protection level, and control methods all reach advanced levels both domestically and internationally.
Compared with traditional electric actuators, the SE series products have significant improvements in mechanical, electrical control, servo motors, manual mechanisms, etc., fully reflecting the advanced technology of the times. Users find it simpler to use, and it can achieve complete connectivity with various control systems.
A complete protection system includes stroke protection, over-torque protection, signal disconnection protection, motor overheating protection, phase correction, and phase loss protection, etc. At the same time, various faults and statuses have passive contact outputs. The actuator itself is equipped with an operation button, facilitating on-site debugging and maintenance.
The performance and technical indicators of the SE series electric actuators comply with the standards JB/T219-2016 "Electric Actuators for Industrial Process Measurement and Control Systems", JB/T 2920-81 "Type, Basic Parameters, and Connection Dimensions of Electric Devices for Valves", GB/T3836.1-2021 "General Requirements for Equipment in Explosive Atmospheres", GB/T3836.2-2021 "Equipment Protected by Flameproof Enclosure 'd' in Explosive Atmospheres", GB/T12476.1-2013 "Electrical Equipment for Flammable Dust Environments - Part 1: General Requirements", GB/T12476.5-2013 "Electrical Equipment for Flammable Dust Environments - Part 5: Protection by Enclosure Type tD", and GB/T4208-2017 "Classification of Degrees of Protection Provided by Enclosures".
Product Technical Features
• High protection level structural design
1. The SE series electric actuators pay full attention to the design of the sealing structure at the interface during the overall planning of the machine, using circular, long stop, sealing ring, and other combined sealing design methods to ensure that the protection performance of the joint surface reaches IP68.
2. Considering the actual working conditions of customers, a double sealing structure design is adopted. The external wiring terminals and control units are isolated and sealed.
3. The sensing element uses an 18-bit multi-turn absolute encoder, allowing the SE series products to truly achieve non-intrusive settings and debugging without opening the cover. This ensures that each product maintains the sealing surface in its factory state from start to finish.
• Advanced Design Concept
The SE series intelligent electric actuators are carefully designed by domestic experts and technical teams with over thirty years of experience in the electric actuator industry, utilizing currently advanced professional technology to develop advanced products with independent intellectual property rights, which will surely promote the upgrade of design, manufacturing, and use of electric actuator products in China.
• Good anti-interference technology
The SE series products greatly enhance the stability of actuator operation by selecting anti-interference components and applying technologies such as delayed sampling and noise filtering to mitigate signal interference from surrounding high-power, high-current, and high-frequency equipment.
