Vacuum degasser is a solids control equipment used in oil & drilling processing to remove the gases in the drilling fluids. If the gases that generates in the down hole drilling do not remove from the drilling mud, it may cause bubbles, and reduce the performance of other solids control equipment, and also may cause well kick. So to avoid potential problem in drilling, a degasser is a must for the solids control system. While for some shallow well, such as coal bed methane ( CBM ) exploration, or horizontal directional drilling, degasser is not a must.

Techniques to Extend Lifespan of Vacuum Degasser:

1. When the vacuum degasser is rolling, it is necessary to check its vacuum gauge all the time and adjust vacuum degree between 0.03~0.05 to ensure the normal operation.

2. The rotor and suction pipe inside vacuum chamber should be washed clean after the machine is used. Then cut off the electricity, unload the blind(i.e. the oval blind flange), examine the condition of parts, remove the foreign objects and wash clean the inner wall and rotor with high-pressure water pipe.
 

3. Weekly cleaning should be performed on the head cover of vacuum chamber to keep dirty stuff from blocking gas passage. The gas collector and bubble separator on head cover can be washed by clean water. While doing these, unconnect the vacuum pipelines, undo the pipe plug and gauge stand, then insert high-pressure water pipe for 3-5 mins each time.

4. The aforementioned cleaning should be carried out every time when drilling work is completed so as to ensure the normal operation for next time.

5. Lubricate the spindle bearing with 250-300mL grease every other month.

6. As far as vacuum pump is concerned, its bearing should be under frequent examination to keep its temperature, after being lubricated, 15-20 degrees higher than the ambient temperature. When it is above 30℃, vacuum gauge should be watched constantly, water in gas/liquid separator replaced promptly and the water temperature kept under 35℃.

7. In wintertime, immediately discharge the standing water inside gas/liquid separator and pump as the precautions of possible frost crack. After vacuum pump is dismantled and repaired, please note the concentricity of coupling.
