Suction and Discharge valves

Automated pV diagram analysis ( pressure/ volume diagram) is one of the most important methods to determine the condition of valves. The dynamic pressure curve measured is converted to a pV diagram. Feature Automated pV diagram analysis ( pressure/ volume diagram) is one of the most important methods to determine the condition of valves. The dynamic pressure curve measured is converted to a pV diagram, for which particular characteristic values are calculated. These values assigned warning thresholds which result in warning messages when exceeded. Acquisition and analysis of the vibration on the cylinders assists the early detection of mechanical damages. Damaged valves as well as shifted valve opening are detectable.The measurement of valve temperature is the traditional method. But, if there are several valves on the cylinder, costs are a factor as a temperature sensor is required for each valve. Despite having individual measuring locations for each valve, clear assignment of the faulty valve is frequently difficult, due to gas mixing causing “ crosstalk” between the valves.
