The notes of using vacuum degasser2012-09-13
1 The vacuum degasser should make drilling fluid discharged into downstream tank, Gas discharge pipe line should make gas at least can discharged directly up to the surface of the liquid.
2 The thruput of vacuum degasser should greater than the capacity of suction tank.
3 The tail of exhaust pipe should be installed in safety zone, and keep a certain safe distance from wellhead and ground waste water pool. The valve should be installed on the exhaust pipe and separated into two branches, in this way the gas will always be lighted on leeward side of ground waste water pool and wellhead.
Need to be reminded that some toxic gas is heavier than the air, and this toxic gas will gathered in low area, so if working at near exhaust pipe, the workers should watch out. 4 Before starting the vacuum degasser, the tail end of bleeder tube and suction pipe should be immersed in drilling fluid at the same time, otherwise the vacuum degasser cannot work.
5 For avoiding the granular objects enter into the pump, the strainer should be installed on the air inlet of exhaust pipe, the mesh number is 40~60.
6 Before starting, open the ball valve of vacuum pump feed pipe line, and then unscrew the plug of gas liquid separator, filling water, stop filling water when the water overflow, and then screw on plug. At last, turn the coupling by hand or pipe wrench, to ensure there have no stuck phenomenon or other damages.
7 After using, the water in the pump and separator must be discharged.
