2022-07-01
Faults of float gauges include zero drift, inaccurate fullness, temperature effects on most electronic circuits, or vibrations in the environment in which the instrument is installed. This can be solved by adjusting the circuit parameters and calibrating the instrument. The process level has changed, but the buoy level indicator has not. Many fastening bolts are not tightened, or the bolts are loose due to vibration, and the connecting shaft is loose, causing the transmitter to separate from the buoy shaft. The liquid level of the heavy hammer buoy level gauge shows slowly, which may be damaged by excessive friction of the bearing. Sealing disc root aging, leakage is also a common fault.

1.Float level gaugeBuoy inspection and maintenance
The buoy is a mechanical structure that is installed in the tower and tank. It cannot be maintained during the production process, and this situation and failure can only be observed when the process is stopped. So in the maintenance process to carefully check. The mechanical structure of the buoy will directly affect the operation of the equipment. During the production process, the tower and tank pontoon fell off and the pontoon was corroded and failed. When there is a problem with the components of the tower buoy, the measurement work is very passive.
The buoy is a hollow ball that welds two hemispheres together. The inner wall of the buoy is relatively thin, and it is easy to corrode, perforate and wear when using the medium, and the welding hemisphere is also easy to corrode. Pay special attention to inspection. The buoy is connected with the connecting rod by bolts to prevent the mechanical parts of the buoy from falling off and loosening during use. All mechanical fastening parts, such as bolts, threaded joints, fixing nuts, etc., shall be spot welded after tightening.
2.Float level gaugeInspection and maintenance of connecting rod
The length of the buoy is very long, and it is easy to deform and bend under the influence of medium and high temperature, corrosion, and liquid waves, which will change the measuring range of the buoy and increase the dead zone. However, there will be a hidden danger of bending and breaking of the rod. The deformation of the bending rod found in the maintenance should be corrected, reinforced or even replaced. If the fastening nut of the buoy connecting rod is seriously corroded, it should be replaced.
3. Inspection and maintenanceFloat level gaugeConveying mechanism.
Float level gaugeThe mechanical structure is complex, with many parts and many testing sites. The moving parts or fixed parts of the transmission mechanism are easy to corrode in the medium. For example, the corrosion of movable limit holes becomes larger, and the corrosion of limit bolts becomes thinner and smaller. During maintenance, check the degree of corrosion of the limit bolts and hard nuts of the rocker arm. Do a detailed inspection of the drive mechanism, bushings and bolts. Replace and repair the severely corroded parts.
Due to the corrosion of the buoy converter, the gap between the club and the spindle becomes larger, resulting in a larger dead zone, resulting in a larger measurement error of the weight buoy level gauge. But as long as the gap is cleaned, the dead zone will be eliminated, and the club head can be welded to the notch of the spindle. It is also possible to lengthen the thread connecting the bat and the protective sleeve at the end of the floating rod, and drill the thread in the recessed part of the main shaft to make the end of the bat and the main shaft threaded connection.
