Verification and Maintenance of Diverter Rotor Type Steam Flow Meter

Abstract: The verification and maintenance information of the diverter rotor steam flowmeter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Anhui Gujing Tribute Wine Co., Ltd. is a traditional industry that produces liquor as its leading product, and its energy consumption is mainly water, electricity, steam and coal. Among them, the consumption of steam accounts for a large proportion of the energy consumption of the brewing workshop, so the steam flow meter is accurate. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the verification and maintenance of the diverter rotor steam flowmeter. Anhui Gujing Tribute Wine Co., Ltd. is a traditional industry that produces liquor as its leading product, and its energy consumption is mainly water, electricity, steam and coal. Among them, the consumption of steam accounts for a large proportion of the energy consumption of the brewing workshop, so the accuracy of the steam flow meter is particularly important for the brewing workshop. In the past, measurement disputes occurred frequently due to the inaccuracy of the steam flow meter. In order to ensure the fairness of measurement, our company spent more than 100,000 yuan in June 1999 to purchase and build a rotor-type steam flow meter calibration device. To check and repair the instrument in question, so as to prevent the recurrence of steam metering disputes and ensure the accuracy and reliability of the meter data. 1. Verification steps The steps of verifying the steam flowmeter are as follows: First, fill the damping chamber with distilled water. Secondly, observe whether the pointer of the inspected watch is running normally, and whether there is beating or jamming. Third, adjust the two flow basin points of 100% and 50% of the range respectively, and find out the adjustment correction amount from the verification results of these two flow points, and adjust the tested meter according to the correction. 2. Regular maintenance The flowmeter should be regularly inspected and maintained during normal use. The regular inspection and maintenance work is as follows: (1) The graphite bearing works under severe conditions, and the maintenance period should be determined according to the air pressure flow. Generally, the maximum clearance on the rotor shaft is 2mm. If the clearance exceeds 2mm, the graphite bearing should be replaced. After the replacement, the lifting clearance of the rotor is between 0.3~0.5mm. (2) Work under normal flow conditions. If it is found that the large pointer does not move, the counting mechanism in the indicator can be removed. Check whether the moving parts are disconnected and stuck. If there is, it should be repaired or cleaned in time. If the fault is not here, stop the steam transmission. Remove the sealing plate. Check whether the reduction gear is normal. If there is a problem, it should be repaired and cleaned in time, and then inject 4112 instrument oil. (3) For the flow meter that has been running continuously for a long time, it is best to open the plugs of the injection and drainage ports of the damping chamber every few months to release the damping fluid, and inject and flush with clean water from the injection port several times. (4) In order to avoid the influence of sediments in the damping chamber and various components, so as to reduce the performance and accuracy of the flowmeter, it should be verified once a year. 3 Troubleshooting (1) The pointer of the indicator does not rotate stably Cause: The transmission mechanism in the indicator does not rotate flexibly, and there is a clamping phenomenon. Remedy: Find out the inflexible parts for trimming and cleaning. (2) Water turned over at the water inlet or outlet Cause: The sealing gasket lost its sealing effect. Remedy: Replace the qualified sealing gasket. (3) The pointer of the indicator does not rotate or rotates too slowly Reasons: ① The flow rate is less than the required value of the flow range; ② There is a foreign body in the flowmeter stuck on a certain transmission part; ③ A part is damaged. Remedy: ①Increase flow IN and replace the shunt orifice; ②Remove and wash the flowmeter to remove foreign matter; ③Replace the qualified parts and use the flowmeter reasonably. (4) Reasons for out-of-tolerance measurement accuracy ①The installation of the flowmeter is unreasonable; ②There is a lot of water in the pipeline; ③The operating pressure of the flowmeter does not match the indication value of the indicator pressure compensation mechanism; ④The actual flow rate is not within the reasonable flow range; ⑤Damping The damping liquid in the chamber is not full; ⑥ Ex-factory calibration is not allowed to eliminate methods ① Reinstall according to the manual; ② Install a drain valve in front of the flow meter; ③ Adjust the pressure compensation mechanism to make the scale value match the operating pressure of the flow meter; ④ Press the Replace the flow meter with the diverter orifice; ⑤ Fill up with damping liquid water; ⑥ Re-calibrate The above is the entire content of this article.
