Cautions for Installation and Use of Scotch Yoke Pneumatic Actuator
发布时间：2018-12-29 来源：艾德威尔•瑞拓
Before Beijing Ruitou's small tape, you learned about the working principle and structural characteristics of the scotch yoke pneumatic actuator. Today, we will learn about the installation and use of the scotch yoke pneumatic actuator.
1. The pipeline of pneumatic actuator must be cleaned and purged. If there are impurities in the medium, filter valves should be installed on the pipeline before the valve.
2. If installing solenoid valves, pay attention to the connection to ensure good sealing;
3. Installation should ensure the space needed for repairing and disassembling components.
4. Installation and pneumatic valve connection teeth embedded axial clearance not less than 1-2 mm;
5. Bolts connected with pneumatic valves shall not be less than 8.8 grade.
6. When used in open stem valves, check whether the stem extension is consistent with the length of stem sheath.
7. When disassembly is needed, the manual handwheel should be rotated several times before the pneumatic valve is slightly opened.
10. Check the type of pneumatic actuator and whether the parameters meet the site installation requirements and technical requirements.
11. Check the cylinder and position indicator of pneumatic valve to ensure no damage.
12. When welding joints are needed, avoid high temperature transmission to fillers and other places.
13. If the solenoid valve is installed, pay attention to the connection to ensure good sealing.
14. When the pneumatic valve is not used frequently, it should be checked regularly, maintained and operated. It is recommended that the operation time should not exceed 10 minutes at least once a month.
Above is the preparation and inspection for the pneumatic actuator of the switching fork in Ruitou Xiaobian before installation. Here, Beijing Rituo is here. Before using the scotch yoke pneumatic actuator, you must read the instructions carefully to avoid unnecessary problems in the installation process.

8. Installation, disassembly and commissioning shall not damage the sealing surface, sealing parts and explosion-proof surface of explosion-proof electrical installations, and shall be coated with rust-proof oil on the explosion-proof surface, and the electrical cover shall be tightly sealed to prevent rainwater or moisture from entering.
