ZCQ vacuum degasser is a special equipment to deal with gas drilling fluid, which is applied to the mating of the other drilling equipment to eliminate the harmful gas of the fluid, to recover the specific gravity and stabilize the viscosity of the fluid. The vacuum degasser is an important part of drilling solid control system.
The theory of vacuum degasser
The degassers are used to clean the gas in the drilling fluid, to ensure the drilling fluid property relatively stable, to guarantee the steady operation of swirlers. The degassers can be grouped into two kinds: ordinary pressure type and vacuum type. The ordinary pressure degasser is to use the centrifugal to take out gas to invade the mud, with the help of centrifugal force to make the mud spraying in the jet tanks and striking on the wall to make gas releasing.The vacuum degasser is to use the suction of the centrifugal, forming negative pressure in the vacuum tanks, under the action of drilling fluid at atmospheric pressure, through the suction pipe into the hollow shaft, then by umbrella piece of around the hollow shaft assembly, they jet to the skin of tank.
The effect of vacuum degasser
Is a kind of diapose soak gas of drilling fluid, it can quickly get ride of the all kinds of the gas in drilling fluid, have important effect to recovery the proportion, stabily, the porformance of mud, at the same time, may as the agitator of high power, be appropriate to all kinds of mud purfication circulation system. The equipment belongs to degasser of negative pressure, the design structure of scientific and reasonabe, it can realise the effective separation of gas-liquid, to ensure the unblocked of the exhaust pipes.
