RX730 floor regulator cabinet Run Feng provides three pressure detection measures
On the basis of technical parameters adjustment, the pressure of regulator outlet (P2), closing pressure (Pb) and fast safety shutoff valve cut-off pressure (Pq) are tested and debugged periodically. To guide the operation and maintenance management, eliminate faults in time and ensure normal operation. The detection methods are:
A. Pressure at the outlet of the regulator (P2) detection: using the station pressure automatic recorder, 24-hour running pressure test records, analysis of its pressure fluctuations and stability. When abnormal conditions occur, it is considered that the voltage regulator has a fault, should be repaired and maintained in normal operation.

B. Pressure regulator closing (P b) detection: in order to ensure the normal operation of one of the regulator station equipment to meet the gas supply network, first close the valve after another regulator, and then observe the pressure regulator outlet, at this time the outlet pressure will gradually increase, and reach a certain value (P). When P < 1.25P2, it is considered that the regulator is stable in performance and normal in operation; when P > 1.25P2, it is considered that the regulator is unstable in performance and malfunction, and should be repaired immediately.
