Vacuum degasser is one important part but not a phase of solids control, it is used to separate the gas and drilling fluids for safe and envioroment friendly. It is always installed after the shale shaker, and before the desander, desilter, or mud cleaner.
How vacuum degasser works?
Vacuum degassers work by creating lower pressure inside a vessel so air or other gaseous impurities can be removed from a substance, such as water or even molten steel. The air is siphoned from the vessel after pressure is lowered enough to force the gas from the substance. A high-vacuum process environment is maintained for a variety of product testing and laboratory applications. This allows the user to analyze products or materials under a wide range of conditions and under predetermined atmospheric or environmental parameters.
Some of the conditions that can be controlled by vacuum degassers include pressure and humidity, temperature, altitude simulation, electromagnetic radiation, microwave radiation, specific gravity, density and vapor pressure.
Vacuum degasser maintenance
1. After using vacuum degasser should wash rotor and suction tube in the vacuum tank. Turn off power, dismantle hole blocking plate and check spare parts whether are damaged. Clean foreign body in the tube, with the high pressure water pipe flushing tank wall and rotor.
2. The above cleaning work should be performed after each use, to ensure the normal use for again.
3. Every other month, use a grease gun to fill grease into main bearing, the amount is 200ml.
4. After using in winter, timely release water in separator and pump to prevent the cracking.
