Shunt rotor scale steam flowmeter calibration and maintenance

Abstract: the scale of shunt rotor steam flowmeter calibration and maintenance information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Beijing flavoring wine co. , LTD. Is a production of liquor for the leading product of traditional industries, its energy consumption is the main water, electricity, steam, coal. The steam consumption accounts for a high proportion of liquor-making workshop energy consumption, so the amount of steam flow meter instrument accurately. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a shunt rotor scale steam flowmeter calibration and maintenance details. Beijing in producing liquor flavoring liquor shares for the leading product of the traditional industry, its energy consumption is the main water, electricity, steam, coal. The steam consumption accounts for a high proportion of liquor-making workshop energy consumption, so the steam flow measurement instrument is accurate for brewing workshop is particularly important. Used for steam flow measurement instrument of misalignment caused disputes phenomenon occurs frequently, in order to ensure the measuring fair, my company in June 1999 to spend more than 10, ten thousand yuan and construction the rotor steam flowmeter calibration is installed. To have problems of instrument calibration and maintenance, to keep the steam metering disputes happen again. Ensure the meter zui data accurate and reliable. 1. Verification steps steam flowmeter verification steps are as follows: first, the damping chamber filled with distilled water. Second, observe whether checked table pointer running is normal, beating, unsmooth phenomena. Third, the range of 100% and 50% respectively two flow point and make side, from the two flow test results to find the table correction, and according to the revised zui adjustments on the inspection table. 2. Regular maintenance flow meter in normal use process, should be regular maintenance and maintenance. Preventive maintenance and maintenance work is as follows: ( 1) Graphite bearing work under the harsh conditions, shall be subject to pressure flow zui maintenance cycle, generally on the rotor shaft clearance zui to 2 mm high, such as more than 2 mm gap. Graphite bearing which should be replaced. After replacement rotor clearance to 0. 3 to 0. Between 5 mm. （ 2) Work under normal flow conditions. If discover big pointer does not move. Can remove the counter mechanism in the indicator. Check whether there is any disconnect on the movement parts stuck phenomenon, should be timely repair or flush. If fault here should stop losing steam. Remove seal plate. Check whether the gear is normal, there is a problem should be timely maintenance and flush, then note 4112 meter of oil. （ 3) After long-term continuous operation of the flowmeter, zui good every few months to open the limit, Chambers, drain plug emits the damping liquid, from injection water mouth wash with water several times. （ 4) To avoid sediment impact on damping indoor and parts, as to make the performance and precision of the flowmeter to drop, should check once a year. 3 to repair, 1) Pointer rotational instability reason: indicator within each transmission mechanism is not flexible, a clamping phenomenon. Excluded methods: find out the flexible part for renovation and clean. （ 2) Nozzle or outlet turn water reason: sealing gasket sealing function loss. Method: the replacement of qualified sealing washer. （ 3) Pointer doesn't rotate or slowly reasons: (1) flow is less than the flow range requirement values; (2) flowmeter sticking a foreign body in it transmission parts; (3) a portion of the damage phenomenon. Method: (1) increasing flow IN replacing tap hole plate; (2) flowmeter unpick and wash, exclude foreign body; (3) replace the unqualified parts and note the vigilant the rational use of flowmeter. （ 4) Measuring accuracy out-of-tolerance reason (1) meter installation is unreasonable; (2) pipes with large amounts of water; (3) flow meter running pressure do not tally with the indicator value for pressure compensation agencies; (4) the actual flow is beyond the scope of reasonable traffic; (5) damping chamber damping liquid water dissatisfaction; 6. The factory check not elimination method (1) according to the instructions to install; (2) the drain valve installed before the meter; (3) adjusting pressure compensation mechanism, make its scale value consistent with flowmeter operation pressure; (4) according to the flow to replace tap hole plate; (5) filled with damping liquid water; 6 to verify the above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.

One increasingly popular managerial tactic to improve problem-solving performance of mass flow meter is to increase the connectedness, or what academics call clustering, of the organization

The Global mass flow meter Leader. Beijing Sincerity Automatic Equipment Co., Ltd will build a unique portfolio of Sincerity and related brands, striving to surpass our competitors in quality, innovation and value, and elevating our image to become the mass flow meter company most customer turn to worldwide.

mass flow meter can be applied in different ways as low flow turbine flow meter.

mass flow meter receives the updates through industry associations, internal legal counsel, regional associations and legal publications.
