Regarding the material accumulation issue with double-flange level gauges, seek a solution
Thread Content
Many of the level gauges on site have flanges in this upper and lower configuration; there’s no problem with the upper part, but the lower part is equipped with a manual valve, which causes materials to accumulate inside over time as a result of long-term use. It’s fine if production continues continuously, but if production is stopped for a couple of days, the materials will accumulate over time, leading to inaccurate level readings. Do anyone have any good solutions? Can I use a membrane that is convex? The pipe outlet cannot be changed; it cannot be modified.
To address the issue of material accumulation in double-flange level gauges, the following methods are recommended: 1. **Regular cleaning**: Implement a routine cleaning process to remove accumulated substances manually or automatically. 2. **Heating and insulation**: Install heating strips on the flanges or pipes to maintain the fluidity of the material and prevent it from solidifying. 3. **Use diaphragms made of special materials**: Replace them with diaphragms that are resistant to high temperatures or chemical corrosion, in order to reduce adhesion. 4. **Install purge ports**: Add purge ports to the flanges at lower positions, and use regular air blowing inward to remove accumulated debris. 5. **Optimized design**: Consider using a level gauge design that makes it difficult for materials to accumulate, such as sanitary or through-type level gauges. Choosing the appropriate solution based on actual usage conditions helps improve measurement accuracy and device stability. .
Regarding the issue of material accumulation in double-flange level gauges, you can consider the following solutions: 1. **Regular cleaning**: Install quick-release connectors between the manual valve and the level gauge to facilitate regular removal and cleaning of accumulated debris. 2. **Install a purging system**: Add a small purging interface below the level gauge, and use gas or other media to purge the interior regularly in order to remove residues. 3. **Change the material or coating**: Replace it with a material that is less prone to adhesion, or apply an anti-adhesive coating inside the existing flanges and pipes. 4. **Use a vibrator**: Install a small vibrator on the gauge housing; the vibration helps to loosen and remove any deposits inside. 5. **Temperature control**: Enhance the insulation or heating capabilities of the pipes to regulate the temperature of the material, preventing it from solidifying due to low temperatures. When implementing the plan, please choose the most suitable method based on the actual operating environment and the properties of the materials. Hope this helps! .
There is a problem with the installation of the lower flange; that area is meant for waste discharge, and the lower flange should be installed at a certain height above the bottom under high pressure.
The plug-in diaphragm type mentioned by the original poster isn’t unusable either, but if you insert it that far, won’t there be no root valve left? Will you be able to remove the gauge in the future? Based on the poster’s image, I have two suggestions: 1. It is recommended to add a tee at the current pressure sampling point, with the lower port used for waste discharge and the side port for pressure sampling. 2. It is recommended to add a purge ring and set a schedule to blow in nitrogen or circulate the solvent at regular intervals.
Materials tend to accumulate; adjust the expected height of the liquid level on the side. Conduct simulations regularly by the maintenance team, and use flushing water or nitrogen for purging； It’s not easy to accumulate dust; try adding purge ports on the side surfaces above the floor.
It should be placed at a certain height on the side, and then kept warm with steam or hot water. It can be rinsed periodically with nitrogen or water. At the bottom, there are three components: one is the bottom valve, which can be opened to clear blockages; on the side, there is a small pneumatic shut-off valve, followed by the lower flange of the double-flange level gauge. Nitrogen is connected in front of the pneumatic valve. If set for 2 hours, the automatic program raises the liquid level to the simulated value and then shuts off the pneumatic valve. Once the pneumatic valve is fully closed, nitrogen is turned on for one or two minutes; after that, nitrogen is turned off again, and once it is fully shut off, the pneumatic valve is opened to end the simulation.
