Precautions for the use of the rotary cup flowmeter

Abstract: The information on the precautions for the use of the rotary cup flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. Careful use and careful maintenance can ensure that the flow meter works properly and obtains reliable hydrological data. To this end, the following regulations should be noted: 1. The instrument and all accessories should be placed in the instrument case and stored in a wooden cabinet in a dry and ventilated room. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the article on the precautions for the use of rotary cup flowmeters. Careful use and careful maintenance can ensure that the flow meter works properly and obtains reliable hydrological data. To this end, the following regulations should be noted: 1. The instrument and all accessories should be placed in the instrument case and stored in a wooden cabinet in a dry and ventilated room. 2. Before disassembling and washing the instrument, you must be familiar with the structure of the instrument and the method of disassembling and washing. 3. All parts of the instrument can not collide arbitrarily, especially the rotating cup, rotating shaft, yoke and so on. 4. The thimble, top socket, steel ball and other parts that are easy to rust must be frequently added with instrument oil for protection. 5. The head oil chamber must be filled with instrument oil before use. After a certain period of continuous use, the oil storage must be checked. The specific time can be determined experimentally according to the local river characteristics (flow rate, sediment content and water depth). 6. The instrument oil adopts No. 8 instrument oil (GB487). Substitute oils are 25 or 104 to 6 cups of time. This can ensure good contact, clear and stable signal, and at the same time ensure the rotation sensitivity of the rotary cup. Install the counter and turn the rotary cup. At this time, the counter should transmit a signal every 5 times, and the signal should be uniform, clear and stable. The reasons for the failure are as follows: (1) Oxidation layer (burning black), patina or breaking occurs on the contact wire due to too strong current, too long energization time, or too long storage and use time. The former can be used to remove the oxide layer or patina with a sharp knife or fine sandpaper, and the latter should be replaced with a new one. (2) Due to the long use time, the contact wire has residual deformation, resulting in poor contact and unstable signal, which can be adjusted with tweezers. (3) Because the contact wire is pressed too tightly, the signal time is too long and the rotation sensitivity is poor, which can be adjusted with tweezers. (4) Due to the rotation of the transmission mechanism, the contact wire is twisted and twisted, which can be removed and adjusted, and then re-installed. The repair steps are: loosen the upper yoke top screw and remove the eccentric cylinder. (2) Lay the eccentric cylinder flat on the table, open the side cover, unscrew the gear shaft screw, and take out the gear and washer. (3) Unscrew the anti-drop screw. (4) Unscrew the thread crimping nut. (5) Loosen the small hexagon nut and the compression nut with a three-way wrench. (6) Pull out the conduction mechanism from the eccentric cylinder. (7) Use a clock driver to unscrew the set screw that presses the contact wire. (8) Repair according to the cause of the above failure. If it cannot be repaired, take out a new contact wire from the finger bottle and replace it. (9) Fix the contact wire with the set screw and apply butter to the head of the set screw. (10) Install the set of parts back to the eccentric cylinder in the corresponding order [(6) to (3)] above. When installing, it should be noted that the contact wire should be located just above the contact claw of the gear. If the position is incorrect, it should be removed and re-installed. (11) Reinstall the washer, gear and gear screw. (12) Test according to the aforementioned technical requirements, and adjust the contact condition of the contact wire. (13) Back up the side cover and screw it tightly. 3. Counting equipment Check according to the instruction manual of the counter. After the above tests have proved that the work of each part is indeed reliable, the indoor preparations are over. The above is the whole content of this article.
