I have two questions for the experts here
Thread Content
I encountered two problems on the night shift last night; I would appreciate it if you experts could give me some advice! 1. The Siemens positioner controls the cylinder valve; the valve is stuck and there is dirt in the pipeline. What is the fault code for the Siemens positioner in this situation? Second, the operating pressure is 10 Mpa; a differential pressure transmitter is used to measure flow rate. It is required that the gauge head be emptied. Considering safety factors, I did not carry out this task. The medium in question is oil vapor – was my decision correct? First, thank you all, masters!
I. When a Siemens positioner encounters a stuck valve or dirt in the pipelines, the specific error codes can be found in the manual corresponding to the model of the positioner; errors related to the movement of the actuator are usually displayed, such as travel limit or positioning errors. It is necessary to consult the manual for the corresponding model of locator to determine the exact fault code. II. At an operating pressure of 10 Mpa with oil and gas as the medium, it is correct to refuse to carry out the emptying operation for safety reasons. Evacuating oil and gas media under high pressure poses safety risks; appropriate safety measures and operating procedures must be followed before proceeding. .
Thank you! I’ll check the manuals related to Siemens positioners. As for work, I’ll be more careful during night shifts from now on!
As an additional suggestion, it’s best to take a look at the safety operating procedures for your position. One must act in a way that is based on reason and evidence. For reference.
