Installation of split-flow rotor type steam flow meter (superheated steam flow meter)

Abstract: The installation information of the shunt rotor type steam flow meter (superheated steam flow meter) is provided by the excellent flow meter and flow meter production and quotation manufacturers. In domestic industrial and mining enterprises, especially in chemical and light industry and electric power industries, steam is often used between enterprises and is often an energy that needs to be metered. The shunt rotor type steam flowmeter is due to its firm structure, long service life, less maintenance and easy operation. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the installation article details of the shunt rotor type steam flowmeter (superheated steam flowmeter). In domestic industrial and mining enterprises, especially in chemical and light industry and electric power industries, steam is often used between enterprises and is often an energy that needs to be metered. The shunt rotor type steam flowmeter is often selected as an instrument for measuring steam consumption by users because of its firm structure, long service life, less maintenance and maintenance, simple operation, no need for additional power supply, and low requirements for the working environment. The following situations are only for your reference. Installation and operation of the split-flow rotor steam flowmeter This requires that the pipeline cannot be close to the ground and there must be room for the installation of the indicator of the flowmeter. 2. The perpendicularity between the vertical axis of the split-flow rotor steam flowmeter and the ground should be less than 5 degrees, otherwise it will easily affect the measurement accuracy. The flowmeter should have a straight pipe section greater than 10D before the steam inlet and a straight pipe section greater than 5D after the exit. . 3. The inner diameter of the pipeline should be the same as the nominal diameter of the flowmeter. When the actual diameter of the pipeline used is inconsistent with the nominal diameter of the flowmeter, in addition to the required front and rear straight pipe sections installed before and after the inlet and outlet of the steam flowmeter, it can be installed according to the actual pipeline diameter. Expansion tube for transition connection. 4. A pressure gauge should be installed on the straight pipe section measured by the inlet of the steam flowmeter in order to detect the working pressure of the steam flowing through the pipe. The flowmeter should be installed under the steam trap to remove liquid phase water. 5. After the steam flowmeter is installed, the orientation of the indicator dial of the flowmeter is sometimes inconvenient for reading. At this time, it is easy to remove the bolt connecting the indicator and the damper and rotate the indicator 90 degrees or 180 degrees to set the orientation of the indicator dial. The location of the reading. 6. It should be reminded that the shunt rotor steam flowmeter must fill the damper cavity with damping fluid before running. The water injection hole, exhaust hole and the bolts on the drain hole on the damper can be removed and injected into the damping fluid to be drained. When the liquid flowing out of the hole is free of yellow rust and dirt, tighten the bolts on the drain hole and continue to inject damping fluid to the overflow for 30 seconds. When the liquid level does not change, tighten the bolts on the water injection hole and the exhaust hole. 7. The valves before and after the flowmeter pipeline should be slowly opened each time the steam is passed through to avoid damage to the flowmeter due to excessive instantaneous flow. When the pointer on the steam flowmeter indicator is rotating steadily, it means that the flowmeter is in normal operation. middle. For the accuracy of measurement, you can often check whether the working pressure and the pressure of the indicator pressure scale are consistent. If they are inconsistent, you can make appropriate adjustments to improve the measurement accuracy. The flowmeter can also calculate the instantaneous flow through manual timing. 8. The so-called damping fluid, antirust fluid and antifreeze fluid. Anti-rust liquid is a mixture of 0.5ml boiler anti-scaling agent, 0.5ml deoxidizer and clean water. In cold winter, such as intermittent use of flow meter, attention should be paid to adding anti-freezing liquid. Anti-freezing liquid is an aqueous solution containing about 50% ethylene glycol. The above is the whole content of this article instead of antifreeze for automobiles. You are welcome to inquire about the flowmeter selection and quotation of our factory.
