Problems encountered in bar flowmeter

What is the problem of flowmeter

Common fault 1: crude oil flowmeter reversal

(1) The upstream and downstream suddenly shut down the pump, did not immediately notify, the flowmeter stopped operation, did not immediately close the import and export trade valve, when the level meter of the oil storage tank is very high, the flowmeter reverses and the crude oil flows back.

(2) When the working pressure at the inlet of the flowmeter is less than that at the inlet and outlet, the flowmeter reverses.

(1) Common internal cavity of flowmeter: first, the inlet valve of flowmeter is not fully opened, which makes the body of flowmeter cavity enter into many gases, causing abnormal noise; second, there is dirt in the body of flowmeter cavity or abnormal noise will occur due to loose screws; third, the rotating part of the body of flowmeter cavity, such as waist wheel or driving gear, motor rotor and middle baffle or There is friction with the metering chamber cover. Abnormal noise will also be found. Common fault 2: abnormal sound of flowmeter

(2) Flow of powder flowmeter: if the measured crude oil flow is too large and exceeds the allowable rated flow range, the rotating part of the metering chamber will rotate rapidly, and abnormal noise will occur immediately.

(1) The flow of measured crude oil is too low, which is less than the allowable flow range, so the marked value of crude oil flowmeter is slightly lower. Common fault 3: flow indicator value is slightly low

(2) If leakage occurs before entering the flowmeter, the flow measured by the flowmeter is less than the flow of specific oil. In addition, the operating pressure of the flowmeter will be slightly lower.

(3) Part of inner chamber of flowmeter: part of inner chamber of metering leaks.

(4) The liquid level of the measured liquid is too high. According to the analysis of the above several types of mechanical faults, we can compare the common faults that will occur in the normal operation of the flowmeter, do a good job in the normal maintenance work, reduce the incidence of common faults, and deal with the common faults timely and properly, so that the crude oil flowmeter can operate under all normal conditions, improve the metering degree, and ensure the smooth development of production safety.
