Radar level meter plays an irreplaceable role in solid dust measurement. Jining Tongchuang Instrument Co., Ltd. is committed to the production of radar level meter and level meter with a dedicated attitude. Made a certain summary of the common problems of radar level gauges, and solutions and skills to solve some problems encountered
Tongchuang radar level meter has the advantages of small level measurement dead angle, high continuous wave measurement accuracy, little influence by the characteristics of the measured medium, wide measurement range, high temperature resistance, strong high pressure capability and non-contact measurement method. The coal industry has been widely promoted and applied.
Due to the complex environment of the measured object, the high temperature, high pressure and high corrosion, as well as the serious influence of dust, vibration, steam and many other reasons, the radar level meter frequently fails, and the technicians maintain a large amount of the instrument, which seriously affects the production equipment. Therefore, it is necessary to understand the daily failure problems of radar level gauges and their solutions. The following has sorted out the troubleshooting methods of the radar level gauge for you, hoping to help you.
The first point is to check whether the power supply of the radar level gauge is normal.
If it is found at the production site that the radar level gauge changes very slowly after the material level rises to a certain value, you should immediately check whether the power supply of the radar level gauge is normal, and the relevant staff should also check the radar level gauge in detail during daily maintenance. The power-on condition, whether there is normal output after power-on. If the material level changes slowly or does not change at all, it is necessary to check whether the fuse of the equipment is burned out at the first time. If there is no current output, it can basically be judged that there is a problem with the instrument, and it should be replaced or repaired according to the situation. In addition, the relevant personnel also need to strengthen the daily maintenance work, and conduct regular outages for maintenance, so as to ensure the normal operation of the radar level gauge instrument.
The second point is that the antenna is stained and crystallized
When the lightly polluted oil tank fails, the possibility of antenna contamination and crystallization should be considered first. The solution is to wear suitable protective equipment after the power is off, remove the radar and put it down tilted, and wipe off the dirt or crystals with a rag. Do not bend or damage the antenna, handle it with care, and avoid scratching with iron to avoid damaging the antenna skin. Check whether the communication equipment is normal
The third point, the use temperature
In order to make the Tongchuang radar level gauge measure normally, it should be ensured that the internal temperature of the radar level gauge is lower than 50°C. Generally speaking, radar level gauges are used to measure high temperature media. Therefore, the outer casing of the radar level gauge is made of materials with strong heat resistance. If the internal electronic components exceed this value, ice water must not be used for cooling. Even the radar level gauge will be paralyzed. A small amount of wind can be blown into the radar head with a copper pipe to scientifically reduce the internal temperature of the radar level gauge.
Fourth, the system displays an error message
The system of the radar level gauge often displays error messages. Generally, the cause of this failure is that the power supply is cut off before the end of data storage, and it is necessary to perform a calibration reset and re-calibration. If the alarm still sounds after the calibration is reset and re-calibrated, the electronic module of the radar level gauge needs to be replaced.
The fifth point, diffuse reflection
If the material level is low or there is no material level, the reason for the large ZUI may be that there are brackets and pipes at the bottom of the test container, or steam is generated during the process, which causes diffuse reflection to the radar wave and causes the material level to fail. After the process level is normal, restart it and it will automatically recover. The diffuse reflection caused by the steam caused by the radar level gauge will automatically recover when the temperature is normal.
