It is necessary to install a vacuum degasser for their removal from the drilling fluids since the invading gases may impact mud properties, cause safety risks and affect the lifespan of some equipment. Vacuum degasser has found wide application in drilling fluids circulating system, forcing the gases(such as, CH4, H2S, etc.) out of entrained drilling fluids(mud) so that mud properties(including density, viscosity) are well preserved.

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, un-connect the vacuum pipelines, undo the pipeplug 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.
