Caused by the failure of the air-tightness of the implementing agencies

Performance caused by the failure of the air-tightness of the implementing agencies for the response time increases stem sluggish action. The analysis is as follows.
1 pneumatic diaphragm actuator diaphragm is not pressed. The diaphragm is not pressed or input signal of gas leakage caused by uneven force uniform, the executing agency to become sluggish response to signal changes, the response time increases. If you install a valve positioner, its effect will be reduced. Troubleshooting method is check, brushing with soap and water and eliminate the leakage point o
Pneumatic piston actuator piston seal ring wear. Causing the control valve can not respond quickly to stem insensitive action. Troubleshooting method is to replace the seal ring, and check whether the cylinder wall wear.standard air cylinder
Pneumatic diaphragm actuator diaphragm rupture. Performance of the stem insensitive can hear the sound of the gas leak. Troubleshooting replacement of the diaphragm, and should be checked limiting device or tray for burrs o
Connecting pipelines leak. Cause stem insensitive action, the response time increases. The troubleshooting methods brushing with soap and water connection pipes, check for leaks point, and replace or welding.
Unbalanced force caused by the failure
Unbalanced force caused by the failure of control valve is unstable, loose relationship. Failure analysis as follows.
1 flows to improper. The control valve is installed properly, resulting in actual fluid flow control valve marked the flow of inconsistency, the unbalanced force changes. For example, flow off control valve is installed to the open flow. The Troubleshooting method is reinstalled.
Implementing agencies do not match. To thrust or push torque caused by the control valve action is not in place. The Troubleshooting method is to replace the implementing agencies.hose adapters
