What should be paid attention to in the installation and use of pneumatic actuators
The actuator and regulating mechanism of the pneumatic actuator are unified. There are two versions of the actuator: piston and fork rack. Suitable for high thrust requirements, long piston stroke. Diaphragm stroke is small and can only drive the stem directly. Through the above introduction, we have a certain understanding of the pneumatic actuator. Let's talk about the installation and use of pneumatic actuators for attention:
1. The pipeline of the pneumatic actuator must be cleaned. If there are impurities in the medium, install a filter valve in front of the valve tube.
2. If a solenoid valve is installed, ensure that the connection is secure.
3. Ensure space for repairing and removing parts during installation.
4. The axial clearance between the valve device and the pneumatic valve is not less than 1~2mm.
5. Bolt connecting pneumatic valve shall not be less than 8.8.
6. When used with an open stem, check that the stem extension is the same length as the stem casing.
7. When disassembly is required, the manual wheel should be rotated several times, and then slightly open the pneumatic valve.
8. The window cannot collide with hard objects.
9. Check whether the type and parameters of the pneumatic actuator meet the installation requirements and technical requirements.
10. When welding is required, avoid transferring to solder at high temperature.
11 pneumatic valve is not commonly used, should be regularly checked, maintenance and operation. They were advised to have the procedure at least once a month, lasting no more than 10 minutes.
Through the above description, the pneumatic actuator can be fully prepared and checked before installation, carefully study the manual of the pneumatic actuator, pay attention to the safety in the installation process, avoid omissions, and reduce unnecessary problems in the installation process.
