1. Maintenance of natural gas flowmeter
The maintenance of natural gas flowmeter needs to be carried out regularly, with the core of maintaining cleanliness, regular lubrication, checking sealing and accuracy, and establishing maintenance records. Ensure the cleanliness of the medium in daily life, regularly clean the filter, and prevent impurities from blocking and affecting the flow rate. According to the instructions, regularly add lubricating oil or cleaning solution to the flowmeter with a land-based oil injection port to protect rotating components such as impellers. Check the operating status, electrical connections, and leakage every month. Thoroughly clean, inspect, and recalibrate the impeller surge gauge every six months or so, and be careful not to damage the measuring chamber components during maintenance. When not in use for a long time, the internal cleaning medium should be emptied, dried, and protected with a protective cover, and stored in a dry place. To ensure the accuracy of trade settlement, it is necessary to regularly use standard equipment for calibration. It is recommended to use it at least once a year, and in critical situations, it can be shortened to six months. At the same time, establish a detailed maintenance file to record all maintenance and calibration information for easy management. The installation environment should avoid strong magnetic interference, severe vibration, and exposure to sunlight and rain. Outdoor installation should be covered. If abnormal display or large measurement deviation is found during use, first check the power supply, wiring, and front and rear valves. After confirming that there are no errors, consider whether the impeller is stuck by dirt or th
2. How do electromagnetic flow meters usually be maintained? Waiting for an answer:
The function of the electrode of an electromagnetic flowmeter is to generate an induced potential signal proportional to the measured value. If there is a problem with the electrode, the electromagnetic silver positive flowmeter will not be able to function normally. Therefore, electrode maintenance is very important. Regarding the electrode maintenance of an electromagnetic flowmeter, it is recommended to refer to the following:
1. Before using an electromagnetic flowmeter, it is necessary to calibrate it with a standard pH solution.
. After calibration, before operation, everyone must pay attention to cleaning the electrodes of the electromagnetic flowmeter with distilled water first, and then cleaning the electrodes again with measuring solution.2. If you do not use an electromagnetic flowmeter, when removing the electrode of the electromagnetic flowmeter, be careful not to let the tactile sensor of the electrode collide with a hard object, otherwise any damage will affect the use of the electrode.
