Radar level gauge common faults and processing methods

by:Sincerity Group     2021-06-21
Radar liquid level gauge with dead zone is small, continuous measurement of the level measurement precision, affected by the dielectric properties and large measuring range, high temperature and high pressure resistance ability and using the advantages of non-contact measurement method, widely promotion and application in the chemical industry. Due to the complex object, by the high temperature and high pressure, high corrosion and bubble, stirring, steam, and many other causes serious damage, radar level gauge is frequent malfunction, large amount of instrument maintenance, seriously affected the production plant. Therefore, understanding the radar level gauge daily failure problems and its processing method, it becomes very necessary. Everyone here is for clean the problem of processing method of radar level gauge, hope can help to you. 1. Check whether the power supply is normal if the production site found radar level gauge change very slowly after the level up to a certain value, should immediately check the power supply condition of radar liquid level gauge is normal, the related staff should also be in daily maintenance, check the current condition of radar liquid level gauge in detail, after electrify presence of normal output. Liquid level change slow or no change, need time to check whether a fuse of the device in * burn out, if there is no current output, is basic to judge instrument appear problem, should be replaced as the case or repair. In addition, the instrument should be link to strengthen the management of installation and debugging, to prevent the instrument parameter Settings is not accurate and impact the production. Relevant personnel also need to strengthen the daily maintenance work, regular shutdown maintenance, to ensure the normal operation of the radar level gauge. 2. Check whether the communication equipment is normal if they do not have the communication equipment is normal, can be installed by radar debugging software, read the configuration data of radar surveillance radar sensor. Mainly check the echo of radar sensor can accurate judgment and the difference between false echoes, the intensity of the reflected wave to the expected standard, if the test is no problem, you need to check for other electronic components, if tell the communications unit of radar level gauge case of damage, you will need to see a circumstance to replace components, so as to ensure the normal communication of radar level gauge. Relevant staff in the daily maintenance work, should also strengthen the communication of radar level gauge of inspection, debug software access line can use radar, using the regulator of radar level gauge communications equipment maintenance. 3. Use normal measuring temperature in order to make the radar level gauge, should guarantee the radar level gauge of the internal temperature is lower than 50 ℃. In general, radar level gauge is applied to the measurement of high temperature medium. Therefore, radar level gauge shell with heat resistance strong material, so in general the inside of a radar level gauge can't more than 50 ℃, if the internal electronic components for more than this value, must not use water for cooling, cooling water not only have the effect of temperature and cooling, even can make the radar level gauge. Can use the wind into a small amount of red copper pipe to the radar's header, reduce the internal temperature of the radar level gauge of science. 4. Display value is not accurate values are not accurate is problems common in radar level gauge, lead to the cause of the display values are not accurate, may be the initial set of contrast is not appropriate, or because the plug-in display module connection is not correct, the staff should try to avoid this problem, if they do not have the display value, should be checked the initial set of radar level gauge, and check the display module plug-in connection is normal, if the two are show normal, you will need to further check the output current of radar level gauge whether normal, if the output current is more than 22 ma, is to judge of radar level gauge display module failed, the need for timely replacement. If the output current is less than 3. 5 ma, can judge is the electronic module of radar level gauge appeared fault, need timely replacement of electronic module of radar level gauge. 5. System shows error of radar level gauge system often display an error message, generally the cause of this fault is to cut off the power before the end of data storage, the need for calibration check reset it and try again. If check reset and still alert after calibration, you need to replace the electronic module of radar level gauge. 6. Antenna contamination, crystal light malfunctioning of the slop tank, should first consider the possibility of contamination of antenna, crystallization, processing method, power outages, wear suitable protective equipment, remove the radar tilt down, use cloth to wipe the dirt or crystallization, don't let the noise of the antenna bending is damaged, pay attention to the light to take light put, iron scraping of avoid by all means, so as to avoid damage to the antenna skin. 7. Diffuse reflection if the liquid level is low or no level, ZUI big reason could be test at the bottom of the container has a stent, pipe, or the steam produced in the process, level of radar wave form diffuse and cause failure, at this point, can wait until the process level after normal, reset the automatically restored. While the diffuse reflection caused by steam, such as normal temperature automatically after recovery.
