Installation and use of pneumatic actuators need to pay attention to

pneumatic actuators actuators and regulating mechanism is unity. Actuators are piston, fork type frame two versions. Piston stroke length, suitable for the occasion of high thrust requirements. The diaphragm stroke is small, can only be direct drive valve stem. Through the above introduction, we have a certain knowledge of pneumatic actuators. Let's talk about the pneumatic actuator of what are the precautions for installation and use:

1, the pneumatic actuators must be cleaned. If there are impurities medium, please install a filter valve in front of the valve tube.

2, if the installation of the solenoid valve, please pay attention to the safety of the connection.

3, ensure that in the process of installation maintenance and remove the space required for the parts.

4, valve device and pneumatic valve between the axial clearance should not be less than 1 ~ 2 mm.

5, connecting bolt of pneumatic valve should be no less than 8. 8.

6, and open the valve stem when used together, check whether the stem extension is the same as the stem length of casing.

7, when the need to remove the manual hand wheel shall be rotated several times, then pneumatic valve slightly open.

8, used for electrical equipment installation, disassembly and debugging of hermetic seal, seal and explosion-proof surface shall not be damaged. Explosion-proof surface should be coated rust-proof oil, electrical cover should be tightly closed. Avoid rain or be affected with damp be affected with damp.

9, Windows can't collision with hard objects.

10, check whether the type and parameters of pneumatic actuators is conform to the installation requirements and technical requirements.

11, check valve cylinder and position indicator, and ensure that no damage.

12, when need to welding connection, avoid high temperature transferred to solder, etc.

13, if installed solenoid valve, please pay attention to the safety of the connection.

14, when the pneumatic valve is not often use, should be regular inspection, maintenance and operation. The doctor suggested that they at least once a month operation, no more than 10 minutes.

through the above description, we can be prepared before installation and check the pneumatic actuator, a careful study of pneumatic actuator manual, pay attention to the safety in the process of installation, to avoid omissions, reduce unnecessary problems in the installation process.
