The solution to the failure of the Roots gas waist wheel flowmeter

In the process of using the Roots flowmeter, there will inevitably be some difficult problems to solve the fault. For several problems, the editor has sorted out the following solutions. Let's take a look.

   For the precision measuring instrument such as Roots flowmeter, most of the faults cannot be solved by the user. Usually, once the Roots flowmeter fails, it still needs to be returned to the factory for maintenance, so as to avoid the low effect of instrument troubleshooting. Bury a safety hazard. Of course, for the user, whether the Roots flowmeter is faulty or not still needs to be checked and maintained, because returning to the factory will bring a certain cost burden and operational burden to the user, and among the reasons for the failure of the Roots flowmeter, There are also many problems caused by installation, maintenance, etc. Therefore, although the user unit cannot perform professional maintenance of the Roots flowmeter, it can still solve the internal fault of the Roots flowmeter through investigation, thereby reducing the failure frequency of the Roots flowmeter. , to improve the service life of the Roots flowmeter.

   1. Solutions to eliminate errors

  (1) In the process of selecting a Roots flowmeter, a flowmeter with a relatively suitable flow range should be selected, especially with reference to the actual situation of the measured fluid, and a reasonable flowmeter should be selected, so as to ensure the operation of the Roots flowmeter. effect, while avoiding flow and errors.

  (2) If the phenomenon of water accumulation and oil seepage occurs inside the flowmeter, the flowmeter can be disassembled, the accumulated water inside the flowmeter can be removed, the Roots flowmeter can be cleaned, and the Roots flowmeter can be lubricated according to the usage specifications of the Roots flowmeter. The addition of oil ensures that the Roots flowmeter can be used within standard technical specifications.

  (3) For the bypass pipe valve, the user needs to be able to close the bypass valve tightly and check the bypass valve for leaks to ensure that the bypass valve will not leak the fluid in the Roots flowmeter.

  (4) As for the specific error caused by which reason, the user needs to be able to screen and eliminate it, so as to choose a more targeted countermeasure to solve the error problem of the Roots flowmeter.

   2. Solutions that cannot be measured

   In response to the phenomenon that the Roots flowmeter cannot be measured, the countermeasures that can be taken include checking the air supply pressure to ensure that the air supply pressure is within a reasonable pressure range and adjusting the flow of the fluid to ensure the smoothness of the fluid flow.

  (1) It is necessary to determine the starting flow of the Roots flowmeter to be used, ensure that the fluid flow is within the starting flow range, and avoid the fluid flow being too large or too small to affect the use of the Roots flowmeter.

  (2) For the problem of foreign matter in the metering rotor, the user needs to disassemble the flowmeter and process and remove the foreign matter, so as to ensure the normal operation of the metering rotor and no jamming phenomenon.

  (3) If the Roots flowmeter cannot be measured due to the installation stress, the Roots flowmeter needs to be re-installed, and the reason for the excessive installation stress should be checked, and the pipeline installation stress should be eliminated during the re-installation process.

  3. Solutions to abnormal temperature and pressure

  Check and maintain the temperature sensor and pressure sensor for the abnormal temperature and pressure display of the Roots flowmeter. Because from the perspective of reasons, the reason why the Roots flowmeter has such an abnormal phenomenon is mainly whether the wiring and the temperature and pressure sensor itself are faulty. If it is a wiring fault, it can be adjusted. If the temperature sensor and pressure sensor are faulty, it needs to be returned to the factory for repair.

  4. Countermeasures for abnormal noise

  For abnormal noise and noise, before using the Roots flowmeter, you must first have a basic understanding of the Roots flowmeter, especially its technical indicators, including the selection of flow range, nominal pressure, jingque degree, etc., to choose suitable fluid measurement. Roots flowmeter, and use the Roots flowmeter in strict accordance with the technical indicators after selection. When the flow range is too large, the flow can be adjusted to the standard range, and if the metering rotor collides or the bearing is damaged, it can be returned to the field for maintenance, or the Roots flowmeter can be replaced by the manufacturer. If it is not such an extreme situation, consider whether it is caused by improper installation. If it is caused by improper installation, it can be reinstalled according to the instructions of the Roots flowmeter.

   5. The solution to the gas in the pipeline and no flow in the meter head

  (1) During the use of the Roots flowmeter, when the gas passes through, the metering rotor will make a certain sound, so if there is no rotating sound of the metering rotor, it means that the metering rotor is blocked by foreign matter, and it is only necessary to clean the foreign matter. The sound of the metering rotor running can be heard, indicating that the inside of the Roots flowmeter is not blocked due to foreign matter.

  (2) It is necessary to confirm whether there is a problem with the electronic meter, that is, open the electronic meter and check whether the pulse sensor line is in good contact. If the thread is loose, connect the thread and restart the flowmeter. If the device is normal, it can continue to be used. If the above reasons are all eliminated, it needs to be returned to the factory for repair or replacement by the manufacturer.

  (3) In the process of handling foreign objects, the watch can be removed, and the rotor can be reversed to remove the foreign objects.

  (4) If the metering rotor cannot be turned forward and reverse, it means that the failure is due to other reasons, and in-depth maintenance is required. This is a professional quality that most users do not have and needs to be returned to the factory.

   6. Countermeasures for automatic word movement without flow

  (1) Aiming at the phenomenon of the Roots flowmeter automatically running word without flow, the solution is to check whether there is a problem with the electronic meter, battery, pulse sensor, etc. according to this. Priority is given to checking the electronic watch head. If the electronic watch head is damaged, it will be directly returned to the factory.

  ①The electronic watch head is not damaged, but the battery is exhausted, then replace the battery. If the electronic watch head and the battery are not abnormal, check whether the pulse sensor is operating normally. Turn on the electronic meter and observe whether the connection line of the pulse sensor is loose or disconnected. If there is a problem, connect the connection line. If neither of these two situations occurs, return to the factory directly.

  ②The Roots flowmeter has no flow and automatic word movement is mainly due to the long service life of the flowmeter, and the failure phenomenon that the repair and maintenance are not timely. If the user wants to effectively avoid this kind of failure, it can shorten the maintenance cycle to a certain extent. Increasing the frequency of maintenance can greatly improve the efficiency of the Roots flowmeter.

  (2) Roots flowmeter, as a fluid measuring device with multiple features such as high precision, excellent performance, long life and easy operation, is of great importance in petrochemical, natural gas and other fields. For the user unit, to ensure the application effect of the Roots flowmeter, improve the use efficiency of the Roots flowmeter as much as possible.

  ①It is necessary to have a deeper understanding of the Roots flowmeter. In particular, it is necessary to have a sufficient understanding of the possible fault conditions in the text, and special personnel can be responsible for overhaul and maintenance for some simple fault problems, which can not only reduce the use cost of the user unit, but also improve the Roots flowmeter. use effect.

  ②In the process of using the Roots flowmeter, although the failure problem is inevitable, it is necessary to reduce the failure frequency as much as possible through a series of protection, maintenance, etc., especially the regular inspection of the Roots flowmeter by specialized personnel Work to ensure the safety of the application of the Roots flowmeter, find faults or abnormalities, and promptly check the faults, and return to the factory for repair or replacement in time if there are serious problems. Only in this way can the safety level of the Roots flowmeter be improved, because whether it is a petrochemical industry , or in the field of natural gas, the use of Roots flowmeters involves safety issues. Any minor failure may bring huge harm and hidden dangers. Therefore, it is imperative to improve the application level of Roots flowmeters and reduce maintenance cycles.
